Abstract

<P>PROBLEM TO BE SOLVED: To prevent the player's prompt detection of a change in permissible level defining probability for determining an allowed derivation of prize winning display result in each game. <P>SOLUTION: Winning probabilities of respective winning combinations in internal lottery is determined according to the difference between set values. An RAM is provided with a set-value work area for storing set values independently of work areas for storing data on game status (credit, game state, or the like) other than the set values. When a power source is turned ON while a setting key switch provided in a slot machine is turned ON, setting is changed, and the set values stored in the set-value work area of the RAM can be rewritten. Data stored in the work areas other than the set-value work area of the RAM are not cleared only by turning ON the power source while turning on the setting key switch, and the data are cleared on the condition that the power source is turned ON while the data clear switch besides the setting key switch, is turned ON. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to setting of an allowable stage indicating a probability that it is determined that the derivation of a winning display result is permitted, and initialization of data indicating the progress of a game other than data indicating the allowable stage.

  The slot machine generally includes a variable display device having a plurality of reels on which a plurality of types of symbols are drawn on the outer periphery, and a winning is generated according to a display mode when rotation of each reel is stopped. Depending on the type of winning, the medal as a valuable value is not paid out, but the game shifts to a special gaming state called a big bonus or a regular bonus (hereinafter collectively referred to simply as a bonus). The game progresses in a state advantageous to the player.

  In order for a winning combination including a bonus to occur, it is necessary to win the winning combination in an internal lottery performed in advance (usually when the start lever is operated) and to set a corresponding winning flag. The winning probability of the internal lottery greatly affects the medal payout rate. In the slot machine, it is common to change the set value of the payout rate calculated based on the winning probability of the internal lottery.

  However, since the difference in the set value directly affects the profit obtained by the player, a certain strict procedure is defined for changing the set value. For example, by inserting a predetermined key (managed at an amusement store) into the keyhole and rotating it by a predetermined angle, the power is turned on while the setting key switch is turned on, and the setting change mode is entered. In the setting change mode, the setting switch is operated to change the setting value in sequence, then the start lever is operated and then the key is rotated to return the setting key switch to the original OFF state and determine the setting value. It was. Here, when shifting to the setting change mode, the RAM for storing various data relating to the progress of the game is initialized with the intention of starting a new game with a new set value ( For example, see Patent Document 1).

JP 2004-337272 A (paragraph 0062)

  By the way, since the set value is directly related to the profits that the player can obtain, it is the information that the player wants to know most, but the game store is information that is not desirably detected by the player. Therefore, the setting value is changed in the game store when there is no player in the store, that is, in the time period from closing to opening the next day. Of course, by performing a considerable number of games, it is possible to predict the difference in the set value to some extent by the difference in the percentage of the winning display result derived from the difference in the winning probability of the internal lottery. It was planned and does not cause any problems.

  However, conventionally, when the set value is changed, the data related to the game that was performed immediately before being stored in the RAM is erased. For example, when the bet number set for the credit or the next game is stored as data in the slot machine, the credit or bet number is cleared to 0 when the set value is changed. In addition, when the game state is controlled to be more advantageous to the player than the initial game state such as a big bonus, a challenge bonus, or RT, the game is returned to the initial game state when the set value is changed.

  For this reason, when the closing time of a game store is reached and the player leaves the store while accumulating credits or bets, or when the customer leaves the store while being controlled in a gaming state that is more advantageous than the initial gaming state If the state of the stand is observed when the store opens next morning, the player will know whether or not the setting value has been changed between the closing of the previous day and the opening of the store. It is not desirable for a game store to detect a change in the setting value in this way, and a change in the setting value is detected especially on a table that can be predicted to be a high setting value on the previous day. In some cases, there is a risk that the player will not be able to come close and the operating rate will be reduced.

  The present invention provides a slot machine that prevents a player from being immediately informed even if the permissible stage for determining the probability of permitting the derivation of the winning display result in each game is changed. For the purpose.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using game values (medals), and a variable display device (variable display device 1) that displays a plurality of types of identification information in a variable manner. ) In the slot machine (slot machine 1) in which one game is ended by deriving the display result and winning can be generated according to the display result derived in the variable display device.
Before the display result of the variable display device is derived for each game, the display result of the variable display device is a re-game display result (re-game player ( A pre-determining means (step S403) for determining whether or not to permit the derivation of a plurality of types of winning display results including replay));
Based on an operation of a predetermined setting operation means (starting with the setting key switch 92 turned on, operation of the setting switch 91), it is determined by the predetermination means that derivation of at least one type of winning display result is permitted. Setting value setting means (steps S203 to S207) for selecting one of setting values (setting values 1 to 6) having different probabilities and setting the selected setting value;
A setting value data area (setting value storage work 112-4) for storing setting value data indicating setting values set by the setting value setting means, and means for storing data in a readable and writable manner, and the setting Game data areas (important work 112-1, general work 112-2, special work 112-3, non-saved work 112-5, stack area 112-6) for storing data indicating the progress of games other than values Including data storage means (RAM 112);
When a new set value is set by the set value setting means, the set value data stored in the set value storage area is newly set without rewriting the data stored in the game data area. Set value data rewriting means (step S208) for rewriting the set value data indicating the set value,
Data stored in the game data area on condition that an initialization operation (starting with the setting key switch 92 and the data clear switch 95 turned ON), which is an operation separate from the operation of the setting operation means, has been performed. Data initialization means for initializing (step S111);
A predetermined gaming state, and a gaming state that transitions when a predetermined transition condition is satisfied in the predetermined gaming state and ends when a predetermined termination condition is satisfied. A game state control for controlling a game state among a plurality of types of game states including a re-game different probability state different from the predetermined game state in which it is determined that the derivation of the re-game display result is permitted. Means ,
Holding means for holding data stored in the data storage means even when power supply to the slot machine is interrupted;
The data storage held by the holding means without individually determining whether the set value data among the data stored in the data storage means is appropriate or not when the power to the slot machine is turned on Stored data determination means (steps S104 to S106, S201 to S203, S704 to S707) for determining whether or not the data stored in the means matches the data before power-off.
When it is determined by the stored data determination means that the data stored in the data storage means held by the holding means does not match the data before power-off, the progress of the game is disabled (RAM abnormal error) State) first disabling means (steps S106 (NO), S203 (NO), S706 (NO), S707 (NO)),
Each time a game start operation is performed, the set value data is read from the data storage means, and the set value indicated by the read set value data is within a set value set value range that can be set by the set value setting means. Setting value determination means that determines that the read setting value data is appropriate in some cases and determines that the read setting value data is not appropriate if it is not within the settable setting value range (step S708, S709),
Second disabling means for disabling the progress of the game (RAM abnormal error state) when the setting value determining means determines that the read set value data is not appropriate (step S709 (NO)). When,
Even if the game progress is disabled by the first disabling means and the game progress is disabled by the second disabling means, the game initialization data is generated by the data initialization means. On condition that the data stored in the area is initialized (step S203 (YES)) and a new set value is set by the set value setting means based on the operation of the setting operation means (step S208). And a disabling canceling means (step S112) for canceling the state where the progress of the game is disabled and enabling the progress of the game ,
When the pre-determining unit determines that the read set value data is appropriate by the set value determining unit, the winning display result in the game at a rate according to the set value indicated by the read set value data Whether to allow derivation of
When the setting operation means is operated while being controlled to the re-playing different probability state, and is changed to a setting value different from the setting value set before the setting operation means is operated In addition, after the set value is changed, the re-game different probability state controlled before the set value is changed is continued (the game state controlled before the set value is changed is set) Will continue after the value change (paragraph 0286)),
In the re-playing different probability state after the setting value is changed, the determination probability of the pre-decision means is set to a probability corresponding to the setting value after the change (internally by changing the setting value). Only the winning probability of the lottery changes (paragraph 0287))
It is characterized by that.

In the slot machine, when a new set value is set by operating a predetermined setting operation means, set value data indicating the new set value is stored in the set value data area. Subsequent games are played according to the set values indicated by the set value data newly set and stored in the set value data area. However, even if a new set value is set by the operation of the setting operation means, a separate initialization operation (even if a part of the setting operation means is common, it is not necessary to completely match ), The data stored in the game data area will not be initialized by the data initialization means.

For example, even if the probability of determining that the pre determining means before and after setting the set value to allow derivation of winning display result is changed, the situation in the game that has been performed before setting a new setting value (pre (Except for the determination probability of the determination means) is inherited in the game after setting a new set value . For this reason, since there is no difference in the game situation before and after the setting value is changed, the player does not know that the setting value has been changed.

On the other hand, even if the pre-decision means decides to allow the derivation of the winning display result according to the set value difference, it is only a problem of probability, so the number of games executed is particularly small In the meantime, in the display result derived to the variable display device, the change of the set value is not known to the player. Even if the set value can be predicted to some extent depending on the rate at which the winning display result is derived to the variable display device, a considerable number of games must be played to reach that value . For this reason, in a situation where multiple slot machines are operating in a game store, there is no table that can immediately detect changes in the setting value and the player will not be able to lean on, and the operating rate of each device can be reduced. There is no lowering.

Further, the setting value data stored in the setting value data area is read to determine whether or not the setting value is appropriate. If the set value is not appropriate, the game cannot be progressed properly because the game cannot be progressed properly. Here, in a state where the progress of the game is disabled based on the fact that the set value stored in the set value data area is not within the proper range, the data stored in the game data area is initialized and a predetermined setting is made. If a set value is not newly set based on the operation of the operation means, it is not canceled. For this reason, an appropriate set value is not arbitrarily set on the machine side, and it is ensured that the game is played based on the newly set value, so that the fairness of the game can be achieved.

Conventionally, when the data stored in the data storage means (especially the game data area) in the slot machine is broken, the game cannot be progressed. Once released, it was released and the progress of the game was resumed. Here, when the data in the data storage means is initialized by the reset operation, the default setting value (usually, the setting value with the lowest probability that it is determined that the derivation of the winning display result is permitted) is automatically set. Was to be selected. For this reason, the pre-determining means may not be determined with the probability that the amusement store has intended. Especially when the setting value with the lowest probability is automatically selected, it is disadvantageous for the player. There was a problem that would become larger.

On the other hand, when data including data other than the set value data among the data stored in the data storage means is not normal, the game cannot be progressed properly because the game cannot proceed properly. Become. In order to cancel the state where the game cannot be progressed here, it is necessary to initialize the data stored in the game data area . If a set value is not newly set based on the operation, it is not canceled. For this reason, an appropriate set value is not arbitrarily set on the machine side, and it is ensured that the game is played based on the newly set value , so that the fairness of the game can be achieved.

In a third aspect of the slot machine according to the present invention,
The gaming state control means is a special advantage that is more advantageous for a player than a normal gaming state (initial gaming state, first RT, second RT) including the predetermined gaming state and the re-playing different probability state as a display result of the variable display device. Special gaming state control means for controlling the gaming state to the special gaming state (big bonus) when a special display result (big bonus (1), big bonus (2)) accompanying the transition to the gaming state is derived. comprising the step S1007, S1009),
The slot machine is
The game in the normal gaming state indicates that the pre-determining means allows the derivation of the small role display result (watermelon, bell, cherry) accompanied by the provision of the gaming value when a predetermined special condition is established. Special game control means (steps S1011 and S703) for controlling a special game (regular bonus) determined with a high probability for a predetermined period;
Special game determining means (steps S701 and S702) for determining whether or not the game is controlled by the special game in the special game state is further provided.

As a first example in the slot machine of the third aspect,
The special game control means starts control of the special game in the special game state as establishment of the special condition when the special game determination means determines that the special game is not controlled. (Step S703).

As a second example in the slot machine of the third aspect,
The special game control means starts control of the special game as establishment of the special condition when controlled to the special game state, and starts control of the special game in the special game state. When the predetermined period expires and the control of the special game ends, the special condition is satisfied, and the control of the special game can be resumed in the special game state (variation: end of the big bonus) At the end of the regular bonus, set the regular bonus medium flag).

  In the special game, since it is determined that the derivation of the small role display result is allowed with high probability, it can be expected that the number of game values obtained by the player is increased. In the special gaming state, if it is determined that each game is not controlled by the special game, the game is immediately controlled by the special game. For example, one game is consumed by deriving a display result for controlling the special game. It will not happen. For this reason, the player can quickly obtain the benefit of providing gaming value in the special gaming state. This effect is particularly prominent when the special gaming state is ended when the number of gaming values given to the player reaches a predetermined number.

  In the first example, even when the special game is first controlled after the special state display result is derived, the special game is controlled again when the special game period has ended and the special state has not ended yet. In this case, the same processing is performed. On the other hand, in the second example, when the special game period ends and the special state has not ended yet, the special game can be immediately returned to.

In the fourth aspect of the slot machine according to the present invention,
The variable display device rotates display bands (reels 3L, 3C, and 3R) each having a plurality of types of identification information that can be identified by driving a stepping motor (stepping motors 3ML, 3MC, and 3MR). A display result may be derived from each of a plurality of variable display units capable of variably displaying. in this case,
The slot machine is
A plurality of stop operation means (stop buttons 12L, 12C, 12R) provided corresponding to the plurality of variable display sections and operated respectively when deriving display results in the corresponding variable display sections;
The apparatus further comprises derivation control means (step S404) for causing the variable display device to derive a display result in accordance with an operation procedure of the prior determination means and the stop operation means.

As a first example of the slot machine according to the fourth aspect,
The derivation control means includes
In a situation where a display result has not yet been derived for any of the plurality of variable display units, a variable display unit for which a display result has not yet been derived is displayed at the time when the stop operation means corresponding to the variable display unit is operated. From a plurality of control patterns (FIG. 10: stop control table) that uniquely specify a display result derived with respect to the number of steps of the stepping motor, a control pattern corresponding to the determination result of the predetermining unit is uniquely set Includes a control pattern selection means for specifying (step S905),
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S915).

  In the first example, in a situation where display results are not yet derived for all of the plurality of variable display portions, the stepping motor at the time when the stop operation means is operated for the variable display portions for which the display results have not yet been derived. The control pattern corresponding to the combination of the determination results of the predetermining means of the game is uniquely selected from the plurality of control patterns that uniquely specify the display result derived for the number of steps, and the corresponding variable display Control for causing the display unit to derive the display result is performed. That is, there is only one control pattern that is applied to one determination result of the prior determination means. For this reason, there is no need to further select any one control pattern from a plurality of control patterns with respect to one determination result of the prior determination means as in the prior art by lottery or the like different from the prior determination means. The control for deriving the display result is not complicated.

As a second example of the slot machine according to the fourth aspect,
The derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 10: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the unit is operated Control pattern selection means (step S905) for uniquely identifying the control pattern corresponding to the number of steps when the corresponding stop operation means is operated in the variable display unit for which the determination result of the determination means and the display result has already been derived. Including
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number can be derived as the display result in the variable display unit (step S915).

As a third example in the slot machine according to the fourth aspect,
The derivation control means includes
In a situation where a display result is derived to at least one of the plurality of variable display sections and a display result is not derived to another variable display section, the variable display section for which the display result has not been derived yet From a plurality of control patterns (FIG. 10: stop control table) that uniquely specify the display result derived with respect to the number of steps of the stepping motor at the time when the stop operation means corresponding to the unit is operated Control pattern selection means (step S905) for uniquely specifying a control pattern corresponding to the combination of the determination result of the determination means and the display result in the variable display unit from which the display result has already been derived;
When the stop operation unit corresponding to the variable display unit for which the display result has not yet been derived is operated, the control pattern selected for the variable display unit by the control pattern selection unit is the step at the time of operation of the stop operation unit The display result uniquely specified for the number may be derived as the display result in the variable display unit (step S915).

  In the second and third examples, the display result has already been derived to any one of the plurality of variable display units, and the display result has not yet been derived to the other variable display units. For a variable display unit for which a display result has not yet been derived, a predetermining unit from a plurality of control patterns that uniquely specify a display result derived with respect to the number of steps of the stepping motor at the time when the stop operation unit is operated And the combination of the display results of the variable display section from which the display results have already been derived (or the number of steps when the corresponding stop operation means is operated in the variable display section from which the display results have already been derived). A control pattern is uniquely selected, and control is performed so that the corresponding variable display unit derives a display result. That is, the combination of the determination result of the predetermining means and the display result of the variable display section for which the display result has already been derived (or the number of steps when the corresponding stop operation means is operated in the variable display section for which the display result has already been derived) ) Has only one control pattern applied. For this reason, it is not necessary to further select any one of the plurality of control patterns, and the control for deriving the display result of the variable display device is not complicated.

In the fifth aspect of the slot machine according to the present invention,
The gaming state control means may display a special display result with a transition to a special gaming state that is more advantageous to the player than the normal gaming state including the predetermined gaming state and the re-playing different probability state as a display result of the variable display device ( When the regular bonus, the big bonus (1), and the big bonus (2)) are derived, the special gaming state control means (steps S1007, S1009, etc.) that controls the gaming state to the special gaming state (regular bonus, big bonus). S1011) ,
The pre-determining means is 1 to permit the derivation of both the special display result and the non-special display result (cherry) accompanied by a predetermined payout other than the control to the special gaming state as the winning display result. It includes duplication determining means (regular bonus + cherry, big bonus (2) + cherry, big bonus (2) + cherry) determined in the game.

  When it is determined that the derivation of both the special display result and the non-special display result is permitted in this way, the special display result is derived by deriving the non-special display result as the display result of the variable display device. It is possible to cause the player to expect that it is determined that the game is permitted, and the interest of the game can be improved.

In a sixth aspect of the slot machine according to the present invention,
The gaming state control means may display a special display result with a transition to a special gaming state that is more advantageous to the player than the normal gaming state including the predetermined gaming state and the re-playing different probability state as a display result of the variable display device ( Including special game state control means (steps S1007 and S1009) for controlling the game state to the special game state (big bonus) when the big bonus (1) and big bonus (2)) are derived ;
The slot machine is
A game value storage means (credit counter (important work 112-1)) for storing a game value (credit) owned by the player;
Bet number setting means (one BET button 14 and MAX BET button 15) for setting a bet number using at least the game value stored in the game value storage means;
Game value return operation means (payment button 16) operated when returning the game value stored in the game value storage means;
Return control means (steps S512, S1121: FIG. 17) for performing return control for returning the game value stored in the game value storage means in response to the operation of the game value return operation means;
Bet number setting prohibiting means (step S520) for prohibiting setting of the bet number by the bet number setting means when the game is started;
Return control prohibiting means (step S520) for prohibiting return control by the return control means when the game is started;
Bet number setting prohibition canceling means (step S1124) for canceling prohibition of setting of the bet number by the bet number setting prohibiting means after the game is over;
Return control prohibition canceling means (steps S1101 (NO), S1102) for canceling the prohibition of return control by the return control prohibiting means after the game is over;
Special gaming state ending means (step S1116) for ending the special gaming state when a predetermined special ending condition is established in the special gaming state;
Special termination disabling means (steps S1118 to S1123) for controlling to a disabling state (freezing state) that disables setting of the number of bets for starting a new game when the special gaming state ends. Prepared,
The betting number setting prohibition canceling unit cancels the prohibition of setting of the betting number by the betting number setting prohibiting unit when the disabled state is canceled when the disabled state is controlled.
When the return control prohibition control unit is controlled to the disabled state, the return control prohibition control unit cancels the prohibition of the return control by the return control unit without waiting for the disabled state to be released.

  The disabling means at the time of special termination can cancel the disabled state (freeze state) when a certain period of time has passed since the control to the disabled state started. In addition, the disabled state (stopped state) may be canceled on condition that a predetermined operation has been performed after being controlled to the disabled state.

  In this case, when the disabled state is controlled, the prohibition of the return control is canceled without waiting for the end of the disabled state. For this reason, it is possible to return the gaming value stored in the gaming value storage means even when the setting of the bet number is prohibited because it is controlled in an impossible state. As long as the player's will is reflected, the game value stored as owned by the player can be returned.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. One word of data handled by the CPU 111 is 8 bits (1 byte), and the addresses of the RAM 112 and the ROM 113 are also assigned in units of 8 bits.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The ROM 113 stores programs executed by the CPU 111 and fixed data. The allocation of the addresses of the RAM 112 and the ROM 113 is different between the development model in the manufacturer and the mass production model delivered to the hall. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The random number generation circuit 115 is configured by a counter that counts up and updates the value every time a predetermined number of pulses are generated, as will be described later, and the sampling circuit 116 acquires the numerical value counted by the random number generation circuit 115. . The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function). As a random number for internal lottery described later, a numerical value obtained by processing a numerical value extracted by the hardware random number function by software is used.

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption process described later.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 controls the reel motors 3ML, 3MC, 3MR via the reel relay substrate 103 and stops the reels 3L, 3C, 3R with reference to a winning flag set in the RAM 112 by an internal lottery described later. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer and receives a big bonus medium signal, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  Next, the configuration of the RAM 112 of the game control board 101 will be described. FIG. 4 is a diagram showing the configuration of the storage area of the RAM 112. As shown in the figure, the RAM 112 stores an important work 112-1, a general work 112-2, a special work 112-3, a set value work 112-4, a non-saved work 112-5, a stack area 112-6, and a parity storage. A plurality of storage areas including the area 112-7 are provided.

  Among these storage areas, in particular, the set value work 112-4 is an area for storing a set value for determining a winning probability of internal winning to be described later, and the parity storage area 112-7 is a RAM parity at the time of power-off. Is an area for storing The winning flag storage register and the winning flag storage register, which will be described later, are provided in the general work 112-2, and the special role temporary storage register and the general role temporary storage register are provided in the important work 112-1. A credit counter, which will be described later, is also provided in the important work 112-1. The general work 112-2 is cleared for each game, but the important work 112-1 is not cleared for each game. The RAM 112 is supplied with power from a backup power source even in the event of a power failure, and stores stored data.

  In the slot machine 1, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. The medal payout rate is calculated by the ratio of the expected value of the number of medals that will be paid out to the small role won in the internal lottery described later to the number of medals that the player inserts to set the number of bets Is done. It is not calculated based on the number of medals that will be paid out for the small role that is actually won. As will be described later, when the gaming state is different, the medal payout rate also changes.

  Here, a setting value changing operation by the setting switch 91 will be described. In order to change the setting value, it is necessary to turn on the power of the slot machine 1 by the main switch 94 after the setting key switch 92 is turned on. When the slot machine 1 is started without changing the setting value, the setting key switch 92 may be turned off and the power may be turned on by the main switch 94.

  When the setting key switch 92 is turned on and the power is turned on, a setting change mode in which a setting value can be changed is entered. When the setting switch 91 is operated in the setting change mode, the setting value is updated one by one (when further operation is performed from the setting 6, the setting is returned to the setting 1). Then, when the setting key switch 92 is turned OFF after the start lever 11 is operated, the determined setting value after the change is stored in the setting value work 112-4. However, even when a new setting value is selected and stored in the setting value work 112-4 in the setting change mode, data in an area other than the setting value work 112-4 in the RAM 112 is not always cleared. Absent.

  If the data clear switch 95 is in the OFF state when the setting key switch 92 is turned on and the power is turned on, the data in the RAM 112 is not cleared and the setting change mode is entered, and the setting value changing operation is performed. It becomes possible. On the other hand, if the data clear switch 95 is also in the ON state when the power is turned on with the setting key switch 92 in the ON state, the setting change mode is entered after the data in the RAM 112 is cleared and the setting value is changed. Operation becomes possible. When the setting value changing operation is performed without clearing the data in the RAM 112, the state shifts to a state in which the game can be progressed in the gaming state controlled immediately before the changing operation. When the setting value changing operation is performed after the data in the RAM 112 is cleared, the state shifts to a state in which the game can proceed in the initial game state.

  When the game can be progressed, the games in the slot machine 1 progress one game at a time, but the set value stored in the set value work 112-4 in the internal lottery performed in each game is within the normal range (1 -6) and whether the number of bets is within a normal range (1 for regular bonus, 3 for other). If the set value is not in the normal range, or if the bet number is not in the normal range, it is determined that the RAM is abnormal, and the RAM abnormal error code is set and controlled to the RAM abnormal error state, so that the progress of the game is disabled. It is supposed to let you.

  Further, when the CPU 111 of the game control board 101 detects the voltage drop signal, the power interruption processing is executed. In the power interruption processing, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 of the RAM 112, and stored in the parity storage area 112-7. ing. Here, the RAM parity is the least significant bit of the sum total of data strings (bits at the same position in each address).

  The data stored in the RAM 112 except when the setting key switch 92 and the data clear switch 95 are in the ON state and the data in the RAM 112 is cleared when the control unit 110 of the game control board 101 is activated. RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7, and compared with the RAM parity stored in the parity storage area 112-7.

  If the comparison result of the RAM parity matches when the setting key switch 92 is in the OFF state, the state before the power is turned off is restored based on the state stored in the RAM 112. On the other hand, if the comparison result of the RAM parity matches when the setting key switch 92 is in the ON state, the mode can be changed to the setting change mode and a new setting value can be set based on the operation of the setting switch 91. It becomes possible.

  On the other hand, if the comparison result of the RAM parity does not match, it is determined that the RAM is abnormal again, and the RAM abnormal error code is set to control the RAM abnormal error state, thereby making the progress of the game impossible. ing. The RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated. The RAM abnormality error processing is canceled by setting a new setting value in the setting change mode after the data in the RAM 112 is cleared by setting the data clear switch 95 to the ON state.

  Similarly to the RAM abnormality error state, the setting abnormality error state is not canceled by operating the first reset switch 48 or the second reset switch 93. However, even if the data clear switch 95 is turned off and the data in the RAM 112 is not cleared, the setting error error state is canceled by setting a new setting value in the setting change mode. . On the other hand, error states other than the RAM abnormality error state and the setting abnormality error state are canceled by operating the first reset switch 48 or the second reset switch 93.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles with transition to special gaming status (regular bonus, big bonus) and small roles with payout of medals. There is a re-player who can start the next game without setting the bet amount. FIG. 5A is a view for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when the combination of “BAR-BAR-BAR” is aligned on any of the winning lines (five) in the initial gaming state or RT (first RT or second RT described later). When the regular bonus is won, the gaming state shifts from the initial gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. After the regular bonus (except when provided during the big bonus), the game is controlled to the initial gaming state. Further, while the game state is in the regular bonus, a regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when the combination of “7-7-7” is arranged in any of the winning lines (five) in the initial gaming state or RT. The big bonus (2) is awarded when the combination of “BAR-7-7” is aligned on any of the winning lines (five) in the initial gaming state or RT. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus. In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112.

 The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. After the end of the big bonus, all operations of the player are invalid except for the payment of credits, and the game is controlled to a freeze state in which the game cannot be progressed for a certain period of time. In addition, after the big bonus ends, the game state is controlled to the initial gaming state.

  Even if the regular bonus, big bonus (1) or big bonus (2) is won in the internal lottery to be described later, both “7” and “BAR” are within 5 frames for all reels 3L, 3C, 3R. Since they are not arranged at intervals, if the stop buttons 12L, 12C, and 12R are not operated according to an appropriate operation procedure that makes it possible to win the winning combinations, the winning combinations will not be won. Of course, if you don't win any of these roles without being operated in the proper operating procedure, you will be able to derive a chance that you can derive when you win or not win these roles ( From a point of view, there may be a case where a loss)

  Watermelons are also won in regular bonuses (including those offered during a big bonus) when the combination of “Bell-Watermelon-Bell” is aligned on one winning line, and 15 medals are paid out. . Since the “watermelons” are not arranged at intervals of 5 frames or less for the reels 3L, 3C, and 3R, even if the watermelon is won in the internal lottery described later, the operation timing of the stop buttons 12L, 12C, and 12R May not win a watermelon. In addition, after winning a watermelon in the initial gaming state, the gaming state is controlled to a second RT described later for 100 games.

  Bell is awarded when any combination of “Bell-Bell-Bell” is aligned on any winning line (5 or 1) in any gaming state, and 9 medals are paid out. Since all of the reels 3L, 3C, and 3R have “bells” arranged at intervals of 5 frames or less, the operation timing of the stop buttons 12L, 12C, and 12R if the bell is won in the internal lottery described later. Regardless, you can win the bell. Further, after winning the bell in the initial gaming state, the gaming state is controlled to a first RT described later for 1000 games.

  Cherry will be awarded when the “Cherry” symbol is derived on any of the winning lines (5 or 1) for the left reel 3L in any gaming state. Medals will be paid out. When “Cherry” is stopped at the upper or lower stage of the left reel 3L in a gaming state other than the regular bonus, a total of four medals are paid out since the derivation is made on two pay lines. Since the “bells” are not arranged at intervals of 5 frames or less on the left reel 3L, even if the watermelon is won in the internal lottery described later, depending on the operation timing of the stop buttons 12L, 12C, 12R, May not win. In addition, after winning the cherry in the initial gaming state, the gaming state is controlled to the second RT described later until the next regular bonus, big bonus (1) or big bonus (2) is won.

  The game state is controlled by the second RT not only when winning a watermelon or cherry but also when winning a regular bonus, a big bonus (1) or a big bonus (2). If the regular bonus, the big bonus (1), or the big bonus (2) is won while the gaming state is already controlled by the second RT, the second RT continues until winning of these roles. The RAM 112 of the game control board 101 is provided with a first RT counter and a second RT counter that are decremented each time one game is consumed when the gaming state is the first RT and the second RT, respectively. However, the initial value of 102 is set in the second RT counter as a result of winning a cherry prize, regular bonus, big bonus (1) or big bonus (2). Regular bonus, big bonus (1) or big bonus (2) It will not be deducted until the winning. Details of the first RT or the second RT will be described later.

  Replay is awarded when the combination of “Replay-Replay-Replay” is aligned on any of the winning lines (5) in the initial gaming state or RT. Since the “replays” for the reels 3L, 3C, and 3R are all arranged at intervals of 5 frames or less, when a replay is won in an internal lottery that will be described later, a replay winning is always made. When you win a replay, you won't be paid out medals, but you can start the next game without setting the number of bets again, so the number of bets that you don't need to set in the next game (the regular bonus won't be replayed for 3) This is substantially the same as paying out three medals corresponding to.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 16383) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  FIG. 5B is a diagram showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. It shows the role that has been determined. In the game state of each game, a combination that is a lottery target is referred to. Here, a plurality of winning combinations may be subject to lottery at the same time.

  When the gaming state is a regular bonus (including a case where the bonus is provided during a big bonus), watermelon, bell, and cherry are sequentially read out as a target for internal lottery. When in the initial gaming state, regular bonus + cherry, regular bonus, big bonus (1) + cherry, big bonus (1), big bonus (2) + cherry, big bonus (2), watermelon bell, cherry, replay (initial) ) Are sequentially read out as a target combination of the internal lottery. When the gaming state is the first RT (shown as RT1 in the figure) and the second RT (shown as RT2 in the figure), instead of the replay (initial) in the initial gaming state, replay (RT1) and replay (RT2), respectively. Are sequentially read out as the target combination of the internal lottery. Replay (initial), replay (RT1), and replay (RT2) have different winning probabilities because the storage areas for the number of determination values described later are different, but the other points are common.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is read in accordance with the storage address of the number of determination values registered in the role table stored in advance in the ROM 113. FIG. 5C is a diagram illustrating an example of the role-specific table. The number of determination values may be 256 or more, and cannot be stored for one word. Therefore, each determination value is registered using a storage area for two words. The number of determination values corresponding to the number of bets of each lottery object combination is common regardless of the set value, and is different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Regular Bonus + Cherry, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry are small lottery games, initial gaming state, and a combination subject to internal lottery in the first RT or second RT. The value of the common flag for these roles is 1, and a storage address for a common number of determination values is registered regardless of the set value. The regular bonus, the big bonus (1), and the big bonus (2) are roles that are subject to internal lottery in the initial gaming state, the first RT or the second RT. For these combinations, the value of the common flag is 0, and the storage address for the number of determination values is individually registered according to the set value.

  Watermelons, bells and cherries are roles that are subject to internal lottery in any gaming state. For the watermelon and the bell, the common flag is 1, and the storage address of the common determination value number is registered irrespective of the set value corresponding to the number of bets. For cherry, the common flag is 0, and the storage address for the number of determination values is registered individually according to the set value corresponding to the number of bets.

  Replay (initial) is a role that is subject to internal lottery only in the initial gaming state. Replay (RT1) is a role that is subject to internal lottery only in the first RT. Replay (RT2) is a role that is subject to internal lottery only in the second RT. The common flag for these roles is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  FIG. 6 is a diagram illustrating a storage area for the number of determination values acquired based on the addresses registered in the role-specific table. The storage area for the number of determination values is provided in the RAM 112 for the development model and in the address area allocated to the ROM 113 for the mass production model.

  For example, the address ADD + 0 is an address that is referred to when an internal lottery target role is regular bonus + cherry and a set value is 1-6. The address ADD + 14 is an address that is referred to when the target combination of the internal lottery is big bonus (1) + cherry and the set value is 1-6. The address ADD + 28 is an address that is referred to when the target combination of the internal lottery is big bonus (2) + cherry and the set value is 1-6.

  The address ADD + 2 is an address that is referred to when the target character of the internal lottery is a regular bonus and the set value is 1, and at this time, the value 11 stored here is acquired as the number of determination values. Addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, and ADD + 12 are addresses that are referred to when the target character of the internal lottery is a regular bonus and the set value is 2 to 6, respectively. Regarding the regular bonus, the number of judgment values is individually stored according to the set value, but since the same number of judgment values is stored, the winning probability of the regular bonus is the same at any set value. Yes. Since the regular bonus + cherry has the same number of determination values as the setting values 1 to 6, the winning probability of the regular bonus is the same regardless of the setting value even when the case of overlapping winning with the cherry is included.

  The addresses ADD + 16, ADD + 18, ADD + 20, ADD + 22, ADD + 24, and ADD + 26 are addresses that are referred to when the internal lottery target role is the big bonus (1) and the set value is 1 to 6, respectively. Addresses ADD + 30, ADD + 32, ADD + 34, ADD + 36, ADD + 38, and ADD + 40 are addresses that are referred to when the internal lottery target is the big bonus (2) and the set value is 1 to 6, respectively. With regard to the big bonuses (1) and (2), the number of determination values is individually stored according to the set value, and a different number of determination values is stored, so that the big bonus (1), ( The winning probabilities in 2) will be different.

  The address ADD + 42 is an address that is referred to when the bet number is 3, that is, in the gaming state other than the regular bonus, the target combination of the internal lottery is a watermelon and the set value is 1-6. The address ADD + 44 is an address that is referenced when the number of bets is 1, that is, when the target character of the internal lottery is a watermelon and the set value is 1 to 6 in the regular bonus (including the case where it is provided during the big bonus) . Since the same determination value number 454 is registered in the address ADD + 42 and the address ADD + 44, the winning probability of the watermelon does not differ depending on the gaming state.

  The address ADD + 46 is an address that is referred to when the number of bets is 3, that is, in a gaming state other than the regular bonus, the target combination of the internal lottery is a bell and the set value is 1-6. The address ADD + 48 is an address that is referenced when the number of bets is 1, that is, in a regular bonus (including a case where the bonus is provided during a big bonus), the target part of the internal lottery is a bell and the set value is 1-6. . Since the number of determination values registered in the address ADD + 46 is larger than the number of determination values registered in the address ADD + 48, the winning probability of the bell in the regular bonus is higher than the winning probability of the bell in other gaming states.

  Addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60 are addresses that are referenced when the number of bets is 3, that is, in a game state other than the regular bonus, the internal lottery target is a cherry and the set value is 1-6 It is. Addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 have a bet number of 1, that is, in a regular bonus (including the case where the bonus is provided during a big bonus), the target part of the internal lottery is cherry and the set value is 1 This address is referred to when 6. The number of determination values registered in the addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 is 60 larger than the number of determination values registered in the addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60, respectively. In game states other than the regular bonus, the cherries are subject to lottery overlapping with the regular bonus, the big bonus (1) and the big bonus (2), and the total number of these judgment values is 60. The probability of winning a cherry does not vary depending on the gaming state.

  The address ADD + 74 is an address that is referred to when the target combination of the internal lottery is replay (initial) and the set value is 1-6. The address ADD + 76 is an address that is referred to when the target part of the internal lottery is replay (RT1) and the set value is 1-6. The address ADD + 78 is an address that is referred to when the target part of the internal lottery is replay (RT2) and the set value is 1-6.

  By performing the internal lottery with such a number of determination values, in the initial gaming state, the medal payout rate is smaller than 1 (that is, the internal lottery wins the number of medals inserted for setting the bet number). The smaller the number of medals that will be paid out for a small role). In the first RT, although the replay winning probability is higher than the initial gaming state, the number of replay judgment values is only 1 different from the initial gaming state, so the medal payout rate is almost the same as the initial gaming state and smaller than 1. It has become a thing. In the second RT, the replay winning probability is extremely higher than in the initial gaming state, so that the medal payout rate is increased and is larger than 1 (that is, the internal number of medals to be inserted for setting the number of bets). The number of medals that will be paid out for the small role won in the lottery is larger).

  Further, it goes without saying that the medal payout rate in the big bonus and the regular bonus exceeds 1, and is higher than the medal payout rate in the second RT. That is, the big bonus or the regular bonus is the most advantageous gaming state for the player, and the second RT is the next advantageous gaming state. The relation of the medal payout rate according to the gaming state described here is the same when the set value is any one of 1-6.

  Furthermore, considering the winning probability of watermelon, bell, and cherry in the initial gaming state, the winning probability of the bell that controls the gaming state in the first RT is extremely higher than the winning probability of watermelon and cherry that controls the gaming state in the second RT. high. Also, considering the winning probabilities of watermelon, bell and cherry in the initial gaming state, the number of games from the initial gaming state to the first RT or the second RT is only a few games. The winning probability of the regular bonus, the big bonus (1), and the big bonus (2) is very low compared to the winning probability of watermelon, bell, and cherry. Therefore, in the slot machine 1 according to this embodiment, the number of games executed in the state controlled by the first RT is the largest, and the first RT is the normal gaming state in the slot machine 1.

  Note that the expected value of the number of staying games in the initial gaming state is approximately 4 games, which is the reciprocal of the probability of winning a certain role in the initial gaming state, assuming that the winning combination is not missed. The expected value of the number of stay games in the first RT is 1000 games if only 1000 games are completed. However, when the regular bonus, the big bonus (1) or the big bonus (2) is won, 1RT will end. In this case, the expected value of the number of staying games can be calculated by the reciprocal of the sum of the product of the probability of reaching the 1, 2,..., 1000th game and the probability of ending the normal gaming state in each game. .

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. The random numbers for the internal lottery are acquired by extracting random numbers from the random number generation circuit 115 by the hardware random number function and processing them by software by the CPU 111. When acquiring a random number for internal lottery, a random number for determining notification for determining whether or not to turn on the bonus notification lamp 66 is also acquired. The least significant bit of the random number generated by the random number generation circuit 115 is referred to as the 0th bit, and the most significant bit is referred to as the 15th bit.

  FIG. 7A is a block diagram showing the configuration of the random number generation circuit 115 in detail. As shown in the figure, the random number generation circuit 115 includes a pulse generation circuit 115a, a lower counter 115b, and an upper counter 115c. The lower counter 115b and the upper counter 115c are both 8-bit (1 byte) counters, the lower counter 115b is the 0th bit to the 7th bit, and the upper counter 115c is a total of 16 bits from the 8th bit to the 15th bit. The data signal is output.

  The pulse generation circuit 115a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 111 and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 115a is clocked into the lower counter 115b.

  The lower counter 115b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 115a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. Further, when the level of the seventh bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the seventh bit data signal changes from 1 to 0, a carry signal is output. The carry signal output from the lower counter 115b is clocked into the upper counter 115c.

  The upper counter 115c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 115b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of the 16-bit data signal in which the data signal of the lower counter 115b is the lower 8 bits and the data signal of the upper counter 115c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 115a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 115.

  The sampling circuit 116 includes a latch circuit. Based on a sampling command from the CPU 111 (when the start lever 11 is operated), the sampling circuit 116 latches and latches the 16-bit data signal output from the random number generation circuit 115 at that time. Output the data signal. The CPU 111 extracts numerical data corresponding to the data signal input from the sampling circuit 116 via the I / O port 114 as a random number generated by the random number generation circuit 115. Hereinafter, the data signal output from the random number generation circuit 115 will be described as a random number corresponding to the logical value.

  FIG. 7B is an explanatory diagram until the CPU 111 processes the random number extracted from the random number generation circuit 115 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 115 is stored in a 16-bit general-purpose register 111GR included in the CPU 111.

  When the random number extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR, the CPU 111 uses the other general-purpose register or the work area of the RAM 112 to lower byte of the general-purpose register 111GR (value extracted from the lower counter 115b). And the value of the upper byte (the value extracted from the upper counter 115c) are exchanged.

  Next, the CPU 111 performs an AND operation on the value of the random number obtained by exchanging the upper byte and the lower byte for the extracted random number with 8080h. Since the processing word of the CPU 111 is 1 byte, the logical product operation is actually performed sequentially on the upper byte and the lower byte. The 15th bit and the 7th bit are always 1 by this logical product operation. Further, the CPU 111 shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 111 acquires the value stored in the general-purpose register 111GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 112, and sequentially adds the number of determination values of each combination to this. It becomes. Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 111 are prohibited from the extraction of random numbers from the random number generation circuit 115 to the end of processing. This is to prevent the contents of the general-purpose register 111GR from being rewritten in the interrupt processing routine when an interrupt occurs to the CPU 111.

  Next, storage of results of internal lottery and management of winning combinations will be described. FIG. 8 is a diagram for explaining an area for storing the results of the internal lottery and an area for managing winnings. That is, in the RAM 112, the winning flag storage register (2 bytes) shown in FIG. 8A, the special role temporary storage register (1 byte) shown in FIG. 8B, and the general role shown in FIG. A temporary storage register (1 byte), an index search register (1 byte) shown in FIG. 8D, and a winning flag storage register (2 bytes) shown in FIG. 8E are provided.

  Here, since the winning flag storage register and the winning flag storage register are provided in the general work 112-2, they are always cleared at the end of one game, but the special role temporary storage register is stored in the important work 112-1. Since it is provided, it is not cleared for each game. In addition, a bit that is “unused” in the winning flag storage register and the winning flag storage register is a bit that does not correspond to any combination, and its value is always 0 (provided that the illegal winning is inverted) Except when the data in the winning flag storage register is inverted).

  The winning flag of the lottery role determined to be won in the internal lottery is first set in the winning flag storage register. Here, the fact that the winning flag is set means that the corresponding bit changes from 0 to 1. For example, when the regular bonus is won, the regular bonus winning flag in the most significant bit of the upper byte of the winning flag storage register is set. When the regular bonus + cherry is won, two flags, a regular bonus winning flag and a cherry winning flag, are set in the winning flag storage register.

  When the winning flag for a special role (regular bonus, big bonus (1) or big bonus (2)) is set in the winning flag storage register by internal lottery, the value corresponding to the special role for which the winning flag is set is the special role Written to temporary storage register. If data indicating the winning of a special role (that is, data other than 0) is written in the special role temporary storage register in the normal gaming state or RT, the special role lottery is not performed and the contents can be rewritten. Absent. In this case, a regular bonus winning flag, a big bonus (1) winning flag, or a big bonus (2) winning flag is set in the winning flag storage register according to the value of the special role temporary storage register.

  Even when data indicating the winning of any special role is written in the special role temporary storage register, regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry Although the number of judgment values is acquired, only the watermelon is actually a lottery target and the contents of the special combination temporary storage register are not updated. The data in the special role temporary storage register is cleared to 0 when a special role is won.

  Even in the small role game, the number of determination values of regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry is acquired, but only cherry is actually the lottery target role.

  In addition, when the winning flag of the general combination (small combination or replay) is set in the winning flag storage register by the internal lottery, a numerical value corresponding to the general combination for which the winning flag is set is written in the general combination temporary storage register. The data in the general combination temporary storage register is overwritten and updated for each game according to the general combination winning flag set in the lower byte of the winning flag storage register according to the result of the internal lottery in each game. That is, data corresponding to the result of the internal lottery in the previous game is not written here.

  In the index search register, data in the special role temporary storage register is written in the upper 4 bits, and data in the general role temporary storage register is written in the lower 4 bits. It corresponds directly to the data in the flag storage register. When a stop control table to be described later is created, a table index stored in the ROM 113 is referred to according to the data in the index search register.

  The winning flag storing register has the same configuration as the winning flag storing register, and if a display mode of a winning combination is derived on any winning line as a display result of the variable display device 2, it corresponds. A winning flag is set. Again, the winning flag is set when the corresponding bit changes from 0 to 1. For example, when a symbol combination of “BAR-BAR-BAR” is derived on any winning line, a regular bonus winning flag is set in the winning flag storage register. When the symbol combination “cherry-ANY-ANY” is derived, a cherry winning flag is set in the winning flag storage register.

  When the winning flag is set in the winning flag storage register, it is determined whether or not there has been an illegal winning of the winning combination by using the data in the winning flag storing register and the data in the winning flag storing register. Specifically, all the data of each bit of the winning flag storage register is logically inverted, and this and the data of the winning flag storage register are ANDed for each bit. If the result of the logical product operation is 0, it is determined that there has been no illegal winning, and if it is not 0, it is determined that an illegal winning has occurred.

  For example, consider a case where a replay symbol is derived on a winning line in a state where the regular bonus winning flag and the replay winning flag are set. The data in the winning flag storage register before the logic inversion is “10000000 10000000”. The data in the winning flag storage register after examining the display result of the variable display device 2 is “00000000 10000000”, and logical operation is performed for each bit with “01111111 01111111” obtained by logically inverting the data in the winning flag storage register. The result is “00000000 000000000”, which indicates that no illegal winning has occurred.

  Further, consider a case where a regular bonus symbol is derived on the winning line in a state where only the replay winning flag is set. The data in the winning flag storage register before the logic inversion is “00000000 10000000”. The data of the winning flag storage register after examining the display result of the variable display device 2 is “10000000 00000000”, and “11111111 01111111” obtained by logically inverting the data of the winning flag storage register is logically calculated bit by bit. The result is “10000000 00000000”, indicating that an illegal prize has occurred.

  Next, stop control of the reels 3L, 3C, 3R will be described. The CPU 111 refers to the table index and table creation data stored in the ROM 113 when the reel starts rotating and when the reel is stopped and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to, and the referred stop control table is drawn. Based on the number of frames, control is performed to stop the rotation of the reels 3L, 3C, 3R corresponding to the operated stop buttons 12L, 12C, 12R.

  FIG. 9 is a diagram showing a table index stored in the ROM 113. As shown in the figure, the table index stores the top address of the area where the data for table creation is stored for each internal winning situation. The internal winning status is not determined according to the winning flag storage register shown in FIG. 8A, but is determined according to the index search register shown in FIG. 8D. That is, the start address of the area where the table creation data is stored is registered in association with the value that the data of the index search register can take.

  Even if the internal winning situation is different, if the same control is applied, the same address is stored as the start address of the area where the data for table creation is stored. In this case, the stop control table is created with reference to the same table creation data. Here, the table creation data is made up of drawn-in frame number data indicating the number of drawn-in frames corresponding to the stop operation position, and the address of the drawn-in frame number data to be referred to according to the reel stop status.

  The number-of-drawing frame data referred in accordance with the reel stop status indicates whether all the reels 3L, 3C, 3R are rotating, only the left reel 3L is stopped, only the middle reel 3C is stopped, or the right reel Depending on whether only 3R is stopped, left and middle reels 3L and 3C are stopped, left and right reels 3L and 3R are stopped, and middle and right reels 3C and 3R are stopped. In addition, in a situation where any of the reels 3L, 3C, 3R is stopped, it may differ depending on the stop position of the stopped reel.

  In the table creation data, the address of the drawing frame number data to be referred to is registered for each reel being rotated for each situation. The address of the number of frames to be drawn that should be referred to according to each situation can be specified based on the top address of the table creation data. From this specified address, the number of frames to be drawn that are necessary for each situation can be obtained. It can be specified. Even if the reel stop status and the stop position of the stopped reel are different, the same address is registered as the address of the number of frames to be drawn when the same number of frames to be drawn is applied. In such a case, the same data for the number of drawn frames is referred to.

  Further, the number of drawn frames data is data that can specify the number of drawn frames for each timing when the stop operation is performed. For the reel motors 3ML, 3MC, and 3MR, stepping motors that make one round with a cycle of 168 steps (0 to 167) are used. That is, when the reel motors 3ML, 3MC, and 3MR are driven in 168 steps, the reels 3L, 3C, and 3R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) are defined for one reel. These areas are areas 1 to 21 from the reel reference position. A number is assigned (see FIG. 10).

  On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 1 to 21 from the reel reference position are assigned to symbols on each reel, so symbols 1 to 21 are assigned to each reel. , Area numbers 1 to 21 are assigned in order. The number of drawn frames by area number is compressed and stored according to a predetermined rule in the number of drawn frames data so that the number of drawn frames by area number can be acquired by expanding the number of drawn frames data. It has become.

  FIG. 10 is a diagram illustrating an example of the stop control table. As described above, the stop control table is created with reference to the table index and the table creation data. In the stop control table, as shown in FIG. 10, the timing (reel reference) corresponding to the area number, the area corresponding to each area number is positioned at the stop reference position (in this embodiment, the lower symbol area). The number of frames to be drawn when the operation of the stop buttons 12L, 12C, 12R is detected at the timing at which the number of steps from the position is included in the range of the number of steps of each area number is set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the internal winning status in the game, that is, the top address of the table creation data corresponding to the data in the index search register is acquired. Then, the table creation data is specified based on the acquired head address, and the address of the drawing frame number data of each reel corresponding to the state in which all the reels 3L, 3C, 3R are rotating is acquired from the specified table creation data. Then, the drawing frame number data of each reel stored at the acquired address is developed to create a stop control table for all the reels 3L, 3C, 3R.

  Further, when any one of the reels 3L, 3C, 3R is stopped, or when any two are stopped, the top address obtained at the start of reel rotation, that is, the internal winning status in the game, that is, the index search register The table creation data is identified based on the head address of the table creation data according to the data, and the stopped reel and the unreserved reel pull-in corresponding to the area number of the stop position of the reel are identified from the identified table creation data The address of the frame number data is acquired, the drawing frame number data of each reel stored at the acquired address is expanded, and a stop control table is created for the unstopped reel.

  Next, when the CPU 111 effectively detects any one of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described.

  When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of drawn frames corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of drawn frames until it is stopped is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, an area (stop point in the figure) corresponding to the area number that is the stop position ahead of the number of frames to be drawn from the area (stop operation point in the figure) corresponding to the area number of the stop operation position where the stop operation is detected The vehicle stops at the stop reference position (in this embodiment, the lower symbol area).

  The table index stores only one address as the first address of the storage area of the table creation data corresponding to one internal winning status, that is, one data of the index search register. In the creation data, only one address is stored as the address of the storage area for the number of drawn frame data corresponding to the stop status of one reel (and the stop position of the stopped reel). In other words, the table creation data corresponding to one internal winning situation and the number-of-drawing frame data corresponding to the reel stop situation (and the stop position of the stopped reel) are uniquely determined. The created stop control table is also unique with respect to one internal winning status and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the internal winning status and the reel stop status (and the stop position of the stopped reel) are the same, the reel stop control is performed based on the same stop control table, that is, the same control pattern. Will be performed.

  In addition, a value of 0 to 4 is determined as the number of drawn frames, and it is possible to stop the reel by drawing a maximum of four symbols after detecting a stop operation. That is, the symbol stop position can be designated from a range of up to five frames including the stop operation position at which the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In addition, in the table index, the number of drawn-in frames is drawn so that the winning combination is drawn to the maximum in the range of 4 frames and no winning combination is arranged, corresponding to the case where any combination is won. A predetermined table creation data address is stored. Corresponding to the case of a loss, a table creation data address is stored in which the number of frames to be drawn is determined so that none of the roles can be obtained. Therefore, if any winning combination is won, there will be a stop control table in which the winning combination is drawn to the maximum in the range of 4 frames and the number of drawing frames to be drawn is set so that the winning combination is not aligned. It is created and reel stop control is performed. On the other hand, in the case of losing, a stop control table in which the number of frames to be drawn that do not have any combination is created, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  In the table index, when a special combination and a small combination are won at the same time, or when a special combination is won with the special combination carried over from the previous game (Big Bonus (1) + Cherry, Big Bonus ( In response to 1) + Bell, etc., the number of draws is determined so that the winning special role is drawn to the maximum in the range of 4 frames, and the winning special role is drawn in the range of up to 4 frames. For the non-stop operation position, the address of the table creation data in which the number of drawn frames is determined so that the selected winning combination is drawn to the maximum within the range of four frames is stored, and reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the special roles that have been elected within the draw range of up to 4 frames can be aligned and stopped on the winning line, the control is performed to align and stop them. If you can't draw a special role that you have won in the drawing range of up to 4 frames on the winning line, you can align the symbols of the small role that has been won in the drawing range of up to 4 frames on the winning line. If they can be stopped, control is performed to stop them together, and the symbol of the winning combination is controlled to be stopped in the drawing range of 4 frames. That is, in such a case, priority is given to the control for aligning the special combination on the winning line over the small combination, and the small combination can be won only when the special combination cannot be drawn.

  In addition, the table index includes a range of 4 replays corresponding to the case where a replay player is elected with a special role carried over from before the previous game (such as big bonus (1) + replay). The address of the table creation data in which the number of frames to be drawn is determined so as to be pulled in as much as possible is stored, and reel stop control is performed. As a result, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of up to four frames. “Replay” which is a symbol constituting the re-gamer is arranged at an interval of 5 frames or less for each of the reels 3L, 3C and 3R, and is always stopped at an arbitrary position within the drawing range of 4 frames. be able to. When a special game is carried over from before the previous game and a re-game player is elected, the re-game game will always be awarded regardless of the operation timing of the stop buttons 12L, 12C, 12R by the player. It will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a winning status notification command, a reel rotation command, a reel stop command, a winning information command, and a gaming state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The reel rotation command indicates the timing at which the reels 3L, 3C, and 3R start to rotate, and is transmitted when the rotation of the reels 3L, 3C, and 3R is actually started. The reel stop command indicates the number of symbols stopped at the middle and the other of the reels 3L, 3C, and 3R, and is transmitted when the reels 3L, 3C, and 3R are stopped. The winning information command indicates the type of winning generated according to the display result of the variable display device 2 and the number of medals to be paid out with the winning. The display result is derived to the variable display device 2 and the winning determination is made. Sent when done. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As the effects executed by the control of the CPU 121, a continuous effect that is continuously performed for three game periods, a bonus winning effect that is performed when a regular bonus, a big bonus (1), or a big bonus (2) is won, and a big When the game is started in the initial gaming state, the freezing effect that is performed when the game is in the frozen state after the end of the bonus, the chance effect that is performed when a chance eye is derived as the display result of the variable display device 2 (In fact, there is an initial notification performed at the end of the previous game).

  The freeze effect is an effect in which the image display on the liquid crystal display 4, the sound output from the speakers 7L, 7R, and 7U, and the lighting of various lamps are all stopped for a certain period. This is performed in a period in which the substrate 101 is controlled to be in a frozen state. The CPU 121 of the effect control board 102 can recognize that it is controlled in the freeze state with reference to two game state commands. That is, if the gaming state command received in the previous game indicates the big bonus and the state command received in the current game indicates the initial gaming state, the big bonus ends in the current game and is controlled to the frozen state. I understand that. For this determination, the RAM 122 is provided with an area for storing the past two gaming states.

  In addition, the continuous performance starts with a game that has not won any combination in the second RT, and ends after continuing for three game periods. Whether the second RT to start the continuous performance is the second RT controlled by winning a watermelon or cherry, or the second RT controlled by winning a regular bonus, a big bonus (1) or a big bonus (2) It doesn't matter. The RAM 122 has an area for storing the winning status for the past two times.

  Continuous production is performed regardless of whether the regular bonus, the big bonus (1) or the big bonus (2) is won (including carryover) or not. If it is lost in the internal lottery at the time, it will be done with a probability of 100%, but if the winning flag for these roles is not set, it will not necessarily be done even if it is lost in the internal lottery, so the bonus notice effect It has the character as.

  In order to control the execution of the continuous effect, the RAM 122 is provided with an area for storing a continuous counter for counting the number of remaining games of the continuous effect. If the regular bonus, the big bonus (1), or the big bonus (2) is won at the end of the continuous performance, a bonus confirmation notification that informs the player that the winning combination has been won. Is done.

  In addition, the chance effect is performed when the chance is derived in the variable display device 2, but from the viewpoint of winning, the chance is lost, so whether the chance is derived even if the winning information command is referred to. The CPU 121 of the effect control board 102 cannot recognize how. The display mode derived to the variable display device 2 is determined based on the reel rotation command and the reel stop command.

  The RAM 122 is provided with a stop symbol table for determining the display mode of the variable display device 2 based on the reel stop command. However, since the reel stop command includes only the type of the stopped reel and the number of the symbol stopped in the middle as information, it is impossible to determine what symbol is stopped by this alone. Tables indicating all symbols arranged in 3C, 3R are stored in advance, and symbols stopped on the reels 3L, 3C, 3R are registered in the stop symbol table with reference to this table.

  The initial notification is performed when the received winning situation notification command indicates that the game is in the initial gaming state. The bonus winning effect is performed when the received winning information command indicates winning of a regular bonus, a big bonus (1), or a big bonus (2). At this time, the continuous production being executed is forcibly terminated, and if a bonus winning notification is performed, this is also terminated.

  Hereinafter, processing in the slot machine 1 according to this embodiment will be described. In the slot machine 1, the game is progressed by repeatedly performing the game process one game at a time. For this purpose, the game must be in a state where the game can be progressed. In order to be able to advance the game, the setting value of the normal range is stored in the setting value work 112-4 with the control unit 110 including the CPU 111 activated, and the data stored in the RAM 112 is stored in the data stored in the RAM 112. The condition is that there is no abnormality.

  FIG. 11 is a flowchart showing a startup process executed by the CPU 111 of the game control board 101. This activation process is a process performed when a reset signal is input from the reset circuit of the game control board 101 and the control unit 110 is activated. Since the reset signal is a signal that is output when the power is turned on and when the operation of the control unit 110 is stagnant, the activation process is accompanied by the activation of the control unit 110 that accompanies power-on and a malfunction of the control unit 110. This process is performed when restarting.

  In the startup process, first, the built-in device, peripheral IC, stack pointer, and the like are initialized (step S101), and access to the RAM 112 is permitted (step S102). Then, it is determined whether or not the setting key switch 92 is in an ON state (step S103). If the setting key switch 92 is not ON, the RAM parity is calculated based on all the data stored in the RAM 112 except the parity storage area 112-7 (step S104).

  Next, the RAM parity calculated here is compared with the RAM parity stored in the parity storage area 112-7, that is, the RAM parity calculated and stored at the previous power-off (step S105). Whether or not the data stored in the RAM is normal (step S106).

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the process proceeds to the RAM abnormality error process shown in FIG. If the RAM parities match, the data stored in the RAM 112 is normal, so the register stored in the stack area 112-6 is restored (step S107), and the interrupt prohibition is canceled (step S107). S108), the process returns to the state before the power is turned off.

  If the setting key switch 92 is on in step S103, it is further determined whether or not the data clear switch 95 is on (step S109). If the data clear switch is not on, even if the setting key switch 92 is on, if the data clear switch 95 is not on, a RAM abnormality error will occur depending on whether the RAM abnormality error code is set or not. Then, it is determined whether the activation process has been performed (step S110).

  If the RAM abnormality error code is set, the data in the RAM 112 remains not normal data, and the routine again proceeds to the RAM abnormality error processing shown in FIG. If the RAM abnormality error code is not set, there is no problem in the data in the RAM 112, and only the setting value may be changed, so the process proceeds to step S112. On the other hand, if the state of the data clear switch 95 is ON in step S109, all the data stored in the RAM 112 is initialized except for the used area and the set value work 112-4 in the stack area 112-6. (Set value work 112-4 is rewritten to 0) (step S111). Then, the process proceeds to step S112.

  In step S122, the setting change process shown in FIG. 12 is executed to set a new setting value and store it in the setting value work 112-4. When the prohibition of interruption is canceled after the setting change process is completed (step S113), the game can proceed and the process proceeds to the game control process.

  FIG. 12 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S112. In the setting change process, first, a setting changing flag indicating that the setting changing mode is being set is set in a predetermined area of the RAM 112 (step S201), and the setting value stored in the setting value work 112-4 is read. Temporary storage is performed in a predetermined area of the RAM 112-4 (step S202).

  Next, it is determined whether or not the read set value is in a normal range of 1 to 6 (step S203). If the set value is not within the normal range, the process proceeds to step S205. If the set value is not within the normal range (including the case where the RAM abnormality error processing has been performed due to the abnormality of the set value and the case where the set value is added in the next step S206 and becomes 7 after exceeding the normal range) The read set value is corrected to 1 (step S204), and the process proceeds to step S205.

  In step S205, it is determined whether an operation of the setting switch 91 has been detected. When the operation of the setting switch 91 is detected, the read setting value is incremented by 1 (step S206). Then, returning to the process of step S203, if the set value is 7 as a result of the addition, the set value is corrected to 1 in step S204. If the operation of the setting switch 91 is not detected, it is determined whether or not the operation of the state switch 41 is detected (step S207). If the operation of the start switch 41 is not detected, the process returns to the process of step S203, and again enters the state of waiting for the detection of the operation of the setting switch 91 and the start switch 41.

  When the operation of the start switch 41 is detected in step S207, the changed set value selected at that time is stored in the set value work 112-4 and the set value is confirmed (step S208). Thereafter, the process waits until the setting key switch 92 is turned off (step S209). If it is determined in step S209 that the setting key switch 92 has been turned off, the setting changing flag set in step S201 is cleared (step S210). And it returns to the flowchart of FIG. Returning to the flowchart of FIG. 11, after the prohibition of interruption is canceled in step S <b> 113, the game can be progressed and the game control process is started.

  FIG. 13 is a flowchart showing in detail the RAM abnormality error process executed by the CPU 111 of the game control board 101. In the RAM abnormality error process, the payout display 51 is controlled to display the RAM abnormality error code on the payout display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed. Note that the RAM abnormality error processing shown in FIG. 13 is also performed when an abnormality in the set value or an abnormality in the number of bets is detected during an internal lottery to be described later.

  As described above, in the startup process, when the setting key switch 92 is not in the ON state, the data stored in the RAM 112 is compared by comparing the RAM parity calculated at the time of power-off with the RAM parity calculated at the time of startup. It is determined whether or not it is normal, and the routine proceeds to RAM abnormality error processing. In the RAM abnormality error process, since the RAM abnormality error code is displayed on the payout display unit 21, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled.

  If the RAM parity does not match, the interrupt is not permitted. Therefore, once the process proceeds to the RAM abnormality error process, the setting key switch 92 is activated in the ON state until the interrupt prohibition is canceled. Even if the power is cut off, no power interruption processing is performed. That is, since no new RAM parity is calculated and stored in the power interruption process, the setting key switch 92 is turned on and the data clear switch 95 is turned on even when the control unit 110 is activated. Except in some cases, the RAM parities do not always match, so that the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormality error state is entered, the setting key switch 92 is turned on and the data clear switch 95 is turned on, the data in the RAM 112 is cleared, setting change processing is performed, and the setting switch 91 is operated. As a result, the game cannot be progressed until a new set value is selected and set. That is, after the transition to the RAM abnormal error state, the data in the RAM 112 is cleared, and the state where the game cannot be progressed is canceled on the condition that the setting value is newly selected / set by operating the setting switch 91. The game can be started (restarted).

  On the other hand, even if the setting key switch 92 is in the ON state, if the data clear switch 95 is started in the OFF state, the data in the RAM 112 is not cleared, and only a new setting value can be selected and set. However, if the setting key switch 92 is ON and the data clear switch 95 is OFF while being controlled to the RAM abnormality error state, the RAM abnormality error processing is controlled from the beginning to select a new setting value. Cannot set. Also, the RAM abnormal error state controlled by the fact that the set value or the number of bets is not appropriate in the internal lottery is not canceled unless the data in the RAM 112 is cleared and a new set value is set.

  In an error state other than a RAM abnormal error, there is no problem of a RAM parity mismatch or a problem that the set value is not in the proper range, so that the game progresses only by operating the first reset switch 48 or the second reset switch 93. It is possible to cancel the disabled state and resume the game.

  As described above, when the game can be progressed, the game processing is repeated one by one in the slot machine 1. Hereinafter, each game in the slot machine 1 will be described. The “game” in the slot machine 1 is, in a narrow sense, from the operation of the start lever 11 to the stop of the reels 3L, 3C, 3R. Since the bet number before the operation is set, the medals are paid out and the game state is shifted after the reels 3L, 3C, and 3R are stopped, these accompanying processes are also included in the “game” in a broad sense. . It should be noted that the transmission of commands from the game control board 101 to the effect control board 102 will be described only for those necessary for the description of the present invention, and the description of the transmission of other commands will be omitted.

  FIG. 14 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S401).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S402). If the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay game flag (the replay game flag is erased at this stage). ). Details of the BET process will be described later.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S403). In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel rotation process is performed (step S404). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. . When the rotation of the reels 3L, 3C, 3R is started and stopped, a reel rotation command and a reel stop command are transmitted to the effect control board 102, respectively. Details of the reel rotation process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, is any of the above-mentioned role symbols derived and displayed on the winning line according to the bet number set in the BET process in step S402? A winning determination process for determining whether or not is performed (step S405). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning information command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S406). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the BET process in step S402 will be described in detail. 15 and 16 are flowcharts showing in detail the BET process executed by the CPU 111 in step S402. In the BET process, the value of the BET counter in which the value of the bet number is stored in the RAM 112 is cleared (step S501). Next, whether or not the game is a replay game is determined based on whether or not the replay flag based on the replay winning of the previous game is set in the RAM 112 (step S502).

  If it is determined that the game is a replay game, the value of the BET counter is incremented by 1 (step S503), whereby the value of the BET counter is a specified number corresponding to the gaming state (the replay winning is the initial gaming state) Alternatively, since it occurs at RT, it is always determined whether or not 3) (step S504). Steps S503 and S504 are repeated until the value of the BET counter reaches the specified number. When the value of the BET counter reaches the specified number, the start switch 41 waits for detection of the operation of the start lever 11. Wait (step S505). When the operation of the start lever 11 is detected, the process returns to the flowchart of FIG.

  If the game is not a replay game, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S506). If the value of the BET counter is a specified number, it is determined whether or not the value of the credit counter in which the credit value is stored in the RAM 112 is 50 (step S507). If the value of the credit counter is 50, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path as the payout side (step S508). Then, the process proceeds to step S510. When the value of the BET counter is not a prescribed number according to the gaming state, or when the value of the credit counter is not 50, the flow path switching solenoid 49 is turned on and the medal flow path is set to the hopper 80 side to insert the medal. Is possible (step S509). Then, the process proceeds to step S510.

  In step S510, it is determined whether or not both the value of the credit counter and the value of the BET counter are zero. If neither the value of the credit counter nor the value of the BET counter is 0, it is determined whether or not the operation of the settlement button 16 is detected by the settlement switch 47 (step S511). If the operation of the checkout button 16 is detected, a checkout process is performed to control paying out medals for the values stored in the credit counter and the BET counter (step S512). Details of the settlement process will be described later. Then, the process returns to step S506.

  If both the value of the credit counter and the value of the BET counter are 0, or if the operation of the checkout button 16 is not detected, it is determined whether or not the inserted medal sensor 44 detects passage of the inserted medal (step S513). . If the passage of the inserted medal is detected, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S514). If the value of the BET counter is not a specified number, the value of the BET counter is incremented by 1 (step S515), and the process returns to step S506. If the value of the BET counter is a specified number, it is determined whether or not the value of the credit counter is 50 (step S516). If the value of the credit counter is not 50, the process directly returns to step S506. If the value of the credit counter is 50, the credit counter value is incremented by 1 (step S517), and the process returns to step S506.

  If the passage of the inserted medal is not detected, it is determined whether or not the value of the BET counter is a specified number corresponding to the gaming state (step S518). If the value of the BET counter is a specified number, it is determined whether or not the start switch 41 detects the operation of the start lever 11 (step S519). If the operation of the start lever 11 is not detected, the process returns to step S506. If the operation of the start lever 11 is detected, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path as the payout side. Further, the operations of the single BET button 14, the MAXBET button 15, and the settlement button 16 are invalidated (step S520). Then, the BET process is terminated and the process returns to the flowchart of FIG.

  If the value of the BET counter is not a specified number, it is determined whether or not the value of the credit counter is 0 (step S521). If the value of the credit counter is 0, the process returns to step S506. If the value of the credit counter is not 0, it is determined whether or not an operation of the single BET button 14 is detected by the single BET switch 45 (step S522). If the operation of the single BET button 14 is not detected, it is determined whether or not the operation of the MAXBET button 15 is detected by the MAXBET switch 46 (step S523). If the operation of the MAXBET button 15 is not detected, the process returns to step S506.

  If the operation of the single BET button 14 is detected, the credit counter value is decremented by 1 (step S524), and the BET counter value is incremented by 1 (step S525). Then, the process returns to step S506.

  If the operation of the MAXBET button 15 is detected, it is determined whether or not the value of the credit counter is 0 (step S526). If the value of the credit counter is not 0, the value of the credit counter is decremented by 1 (step S527), and the value of the BET counter is incremented by 1 (step S528). Here, it is determined whether or not the value of the BET counter has reached a specified number corresponding to the gaming state (step S529). If the value of the BET counter is a specified number, the process returns to step S506. If the value of the BET counter is not the specified number, the process returns to step S526. If it is determined in step S526 that the value of the credit counter is 0, the process returns to step S506.

  Next, the payment process in step S512 will be described in detail. FIG. 17 is a flowchart showing in detail the settlement process executed by the CPU 111 in step S512. In the settlement process, the flow path switching solenoid 49 is turned off, and the insertion of a new medal is prohibited with the medal flow path set as the payout side (step S601). Further, the hopper motor 82 is driven in an ON state (step S602).

  Next, it is determined whether or not the value of the credit counter is 0 (step S603). If the value of the credit counter is 0, it is determined whether or not the value of the BET counter is 0 (step S604). If either the credit counter value or the BET counter value is not 0, it is determined whether or not the payout sensor 81 detects the payout of medals (step S605). If no medal payout is detected, the process returns to step S603.

  If a medal payout is detected, it is further determined whether or not the value of the credit counter is 0 (step S606). If the value of the credit counter is not 0, the credit counter value is decremented by 1 (step S607), and the process returns to step S603. If the value of the credit counter is 0, the value of the BET counter is decremented by 1 (step S608), and the process returns to step S603.

  If the value of the credit counter and the value of the BET counter are both 0 in steps S603 and S604, the hopper motor 82 is turned off to stop driving (step S609). Then, the settlement process is terminated and the process returns to the original process.

  Next, the lottery process in step S403 will be described in detail. FIG. 18 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S701). If the gaming state is not the big bonus, the process proceeds to step S704 as it is.

  If the gaming state is in the big bonus, it is determined whether the gaming state is in the regular bonus depending on whether the regular bonus flag is set in the RAM 112 (step S702). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. A regular bonus medium flag is set to the game state and the gaming state is controlled to the regular bonus (step S703). Then, the process proceeds to step S704. If the gaming state is a regular bonus, the process proceeds to step S704 as it is.

  In step S704, the bet number set in the current game is read. Next, based on whether or not the regular bonus flag is set in the RAM 112, it is determined whether or not the gaming state is a regular bonus (including a case where the bonus is provided during the big bonus) (step S705). If there is a regular bonus, it is determined whether or not the read bet number is 1 (step S706). If not in the regular bonus, it is determined whether or not the read bet number is 3 (step S707). If the bet number read in step S706 is not 1, or if the bet number read in step S707 is not 3, a RAM abnormality error occurs, and the RAM abnormality error process shown in FIG. 13 is performed. When the bet number read in step S706 is 1, or when the bet number read in step S707 is 3, the process proceeds to step S708.

  In step S708, the setting value stored in the setting value work 112-4 of the RAM 112 is read. Here, it is determined whether or not the read set value is in the range of 1 to 6 that is a value that should be originally taken (step S709). If the read set value is not in the range of 1 to 6, a RAM abnormality error occurs and the RAM abnormality error process shown in FIG. 13 is performed.

  If the read set value is in the range of 1 to 6, random number acquisition processing is performed, and a sampling command is output to cause the sampling circuit 116 to extract the random number generated by the random number generation circuit 115. The random number for lottery is processed into a random number storage area for internal lottery in the RAM 112 (step S710). Details of the random number acquisition process will be described later.

  Next, in correspondence with the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 5B is sequentially read (step S711). Next, the common flag setting status registered in the role-specific table of FIG. 5C for the read lottery target role is acquired (step S712). As a result, it is determined whether the common flag is set (step S713).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 5C corresponding to the read number of bets for the lottery object to be read is acquired ( Step S714). Then, the process proceeds to step S716. If the common flag is not set, the setting value set in the RAM 112 is read out and stored in the address registered in the combination table corresponding to the number of bets read and the setting value for the lottery target combination. The number of determination values is acquired (step S715). Then, the process proceeds to step S716.

  In step S716, the number of determination values acquired in step S714 or S715 is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S717).

  If no overflow has occurred, it is determined whether there is a combination that is not yet a processing target among the lottery targets in the gaming state (step S718). If there is something that has not yet been processed, the process returns to the process of step S711, and the process continues with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S728.

  If an overflow occurs, it is determined whether or not the lottery target combination read in the previous step S711 is any of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry ( Step S719). In the case of regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, at least the game state in the current game is a regular bonus (if provided during the big bonus) Not included).

  Here, whether the value of the special role temporary storage register is 0, that is, whether the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag has been carried over from the previous game. Is determined (step S720). If the value of the special role temporary storage register is 0, regardless of the current value, the value of the first RT counter is initialized to 0 and 102 is set in the second RT counter (step S721). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Furthermore, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set in the winning flag storage register and the cherry winning flag is set in the winning flag storage register according to the read lottery target (Step S722). Then, the process proceeds to step S728.

  If the value of the special role temporary storage register is not 0 in step S720, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is carried over from the previous game. Only the cherry winning flag is set in the winning flag storage register (step S723). Then, the process proceeds to step S728.

  In step S719, when the lottery target is neither regular bonus + cherry, big bonus (1) + cherry or big bonus (2) + cherry, the lottery target is regular bonus, big bonus (1) or big It is determined whether the bonus is (2) (step S724). If the lottery target is neither the regular bonus, the big bonus (1), or the big bonus (2), the process proceeds to step S727. If the bonus is one of the regular bonus, the big bonus (1), or the big bonus (2), whether or not the value of the special role temporary storage register is 0, that is, the regular bonus winning flag and the big bonus from the previous game. (1) It is determined whether the winning flag or the big bonus (2) the winning flag is carried over (step S725).

  If the value of the special role temporary storage register is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag has been carried over from the previous game, so the process of step S728 is continued. Proceed to If the value of the special role temporary storage register is 0, the regular bonus, the big bonus (1) or the big bonus (2) is won, and the value of the first RT counter is set to 0 regardless of the current value. Initialization is performed and 102 is set in the second RT counter (step S726). Thus, the gaming state is controlled to the second RT until the regular bonus, the big bonus (1), or the big bonus (2) is won. Then, the process proceeds to step S727. In step S727, the winning flag of the lottery object combination is set in the winning flag storage register. Then, the process proceeds to step S728.

  In step S728, the lower byte of the winning flag storage register, that is, a value corresponding to the setting status of the winning flag for the general combination is stored in the general combination temporary storage register. Next, it is determined whether or not the upper byte of the winning flag storage register is 0, that is, whether the regular bonus, the big bonus (1), or the big bonus (2) is not won in the current game ( Step S729). If the upper byte of the winning flag storage register is not 0, the upper byte of the winning flag storage register, that is, a value corresponding to the setting state of the winning flag of the special role is stored in the special role temporary storage register (step S730). Then, the process proceeds to step S733.

  If the upper byte of the winning flag storage register is 0, whether the value of the special role temporary storage register is 0, that is, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2 from the previous game) ) It is determined whether or not the winning flag has been carried over (step S731). If the value of the special role temporary storage register is not 0, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in the upper byte of the winning flag storage register according to the value ( Step S732). Then, the process proceeds to step S733. If the value of the special role temporary storage register is 0, the process proceeds to step S733 as it is.

  In step S733, the value stored in the special role temporary storage register is written in the accumulator of the CPU 111. Further, the value of the lower 4 bits of the accumulator is shifted to the upper 4 bits (step S734). Next, the value stored in the general combination temporary storage register is added to the value stored in the accumulator, and this is stored in the accumulator (step S735). Then, the value stored in the accumulator is stored in the index search register (step S736).

  Furthermore, a winning status notification command is generated according to the setting status of the winning flag of each combination indicated by the winning flag storage register or the index search register, and is transmitted to the effect control board 102 (step S737). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S710 will be described in detail. FIG. 19 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S710. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S801). Next, a sampling command is output to the sampling circuit 116, the random number generated by the random number generation circuit 115 is latched, and the value of the latched random number is input from the I / O port 114 and extracted. The random number value extracted from the random number generation circuit 115 is stored in the general-purpose register 111GR (step S802).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 111GR are exchanged with each other using the work area of the RAM 112 (step S803). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S804). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 111GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 112 (step S805). Then, after permitting the interrupt prohibited in step S801 (step S806), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel rotation process in step S404 will be described in detail. FIG. 20 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S404. In the reel rotation process, first, it is determined whether or not a wait time (for example, about 4.1 seconds) has elapsed since the reel rotation start time of the previous game (step S901). If the wait time has not elapsed, Wait until the wait time has elapsed. If the wait time has elapsed, the timing of the wait time is newly started (step S902).

  Next, the work initialization code at the start of the reel motor rotation is set in the register, and the reel rotation is started (step S903). At this time, a reel rotation command indicating that the reels 3L, 3C, 3R have started rotating is generated and transmitted to the effect control board 102 (step S904).

  Thereafter, the table creation data is identified by referring to the table index corresponding to the value of the index search register, and based on the identified table creation data, the game state of the game, the internal winning status, and the stop of other reels A stop control table corresponding to the situation is created for each rotating reel (step S905). In addition, a work initialization code at the completion of stop preparation is set in the register (step S906). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether any one of the stop buttons 12L, 12C, and 12R has been detected (step S907). If no stop button operation is detected, it is determined whether a reel rotation error (an error determined when the reel reference position is not detected by the reel sensors 3SL, 3SC, 3SR for a certain period or more) has occurred. (Step S908). If no reel rotation error has occurred, whether or not a further insertion error (an error determined when a medal insertion is detected outside the period during which medal insertion is permitted) has occurred, and a payout error It is determined whether or not an error has occurred (error determined when medal payout is detected outside the period in which medal payout is permitted) (steps S909 and S910). If no error is determined in steps S908 to S910, the process returns to step S907.

  If it is determined in step S909 that a loading error has occurred, or if it is determined in step S910 that a dispensing error has occurred, an error code indicating a loading / dispensing error during reel rotation is set in the register (step S910). In step S911, the process proceeds to predetermined error processing (step S912). If the error is released, the process returns to step S907 again.

  If it is determined in step S908 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (step S913), and the process proceeds to a predetermined error process (step S914). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. When the error is released, the process returns to step S903 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  When the operation of the stop button 12L, 12C, or 12R is detected in step S907, the reel motor (any of 3ML, 3MC, and 3MR) corresponding to the operated stop button from the reel reference position at that time is detected. The number of steps (the number of steps as the stop operation position) is acquired and set to the work corresponding to the stop reel (step S915). Here, a reel stop command indicating the type of reel to be stopped and the symbols to be stopped for the reel is generated and transmitted to the effect control board 102 (step S916). Then, it waits until rotation of the reel (any one of 3L, 3C, 3R) corresponding to the operated stop button stops (step S917).

  Then, when the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button is stopped, it is determined whether or not all of the reels 3L, 3C, and 3R are stopped (step S918). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S905. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  As described above, in the reel rotation process, after the rotation of the reels 3L, 3C, and 3R is started, the rotation of the reels for which the stop operation has not been detected is continued until the operation of the stop buttons 12L, 12C, and 12R is detected. Then, on the condition that the operation of the stop buttons 12L, 12C, and 12R is detected, control for stopping the display result on the corresponding reel is performed. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop button 12L, 12C, 12R is detected after the reel rotation is restarted. Control is performed to stop the display result on the corresponding reels on the condition that the operation of the stop buttons 12L, 12C, and 12R is detected by continuing the rotation of the unreeled reels. This is not the case when the data in the RAM 112 is destroyed and cannot be restored to the original state.

  Next, the winning determination process in step S405 will be described in detail. FIG. 21 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S405. In the winning determination process, a winning flag corresponding to the role symbol derived on any winning line of the display result of the variable display device 2 is set in the winning flag storage register of the RAM 112. For example, when the regular bonus symbols are arranged on the winning line of the variable display device 2, the value of the most significant bit of the upper byte of the winning flag storage register is 1 and the values of the other bits are 0 (step) S1001).

  Next, the value of each bit in the winning flag storage register of the RAM 112 is inverted. For example, when only the regular bonus winning flag is set, the value of the most significant bit of the upper byte of the winning flag storage register is 0 and the value of the other bits is 1. Then, the data of the winning flag storage register and the data of the winning flag storage register are logically ORed for each bit (step S1002). Then, it is determined whether or not the result of the logical sum operation in step S1002 becomes 0 (step S1003).

  If the result of the logical sum operation in step S1002 is not 0, it means that the winning combination for which the winning flag has not been set has been won. In this case, the process proceeds to a winning abnormality error process. In the prize abnormality error process, a prize abnormality error code is displayed. Unlike the above-described RAM abnormality error process, it can be canceled by operating the reset switch 48 or the second reset switch 93. The winning abnormality error processing is not directly related to the present invention, and thus detailed description thereof is omitted.

  If the result of the logical sum operation in step S1002 is 0, it is determined whether or not a replay winning is made based on whether or not the replay winning flag is set in the winning flag storage register (step S1004). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S1005). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S1019.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the winning flag storage register (step S1006). If the big bonus (1) is won, the big bonus medium flag is set in the RAM 112 and the value of the special combination temporary storage register is initialized to zero. Also, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1007). Then, the process proceeds to step S1019.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won based on whether or not the big bonus (2) winning flag is set in the winning flag storage register (step S1008). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the value of the special combination temporary storage register is initialized to zero. Also, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1009). Then, the process proceeds to step S1019.

  If the big bonus (2) has not been won, it is determined whether or not the regular bonus has been won based on whether or not the regular bonus winning flag is set in the winning flag storage register (step S1010). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the value of the special combination temporary storage register is initialized to zero. Further, the values of the first RT counter and the second RT counter in the RAM 112 are both initialized to 0 (step S1011). Then, the process proceeds to step S1019.

  If there is no regular bonus winning, the regular bonus medium flag is not set in the RAM 112, and the game state in this game is the initial game state depending on whether both the first RT counter and the second RT counter are 0 or not. Is determined (step S1012). If the game state in the current game is not the initial game state, the process proceeds to step S1019.

  If the game state in the current game is the initial game state, it is determined whether or not a bell is won depending on whether or not a bell winning flag is set in the winning flag storage register (step S1013). If the bell is won, 1001 is set as the initial value of the first RT counter in the RAM 112 (step S1014). Here, in order to set 1001 as an initial value, the value of the first RT counter is decremented by 1 in step S1109 (described later) until the next game is started. This is to secure 1000 games as the number of games. Then, the process proceeds to step S1019.

  If the bell has not been won, it is determined whether or not a watermelon has been won according to whether or not a watermelon winning flag is set in the winning flag storage register (step S1015). If the watermelon has been won, 101 is set as the initial value of the second RT counter in the RAM 112 (step S1016). Here, to set 101 as the initial value, the value of the second RT counter is decremented by 1 in step S1111 (described later) until the next game is started. This is to secure 100 games as the number of games. Then, the process proceeds to step S1019.

  If there is no watermelon winning, it is determined whether or not a cherry is won according to whether or not a cherry winning flag is set in the winning flag storage register (step S1017). If the cherry is won, 102 is set as the initial value of the second RT counter in the RAM 112 (step S1018). Here, by setting 102 as the initial value, how many games have elapsed until the value of the second RT counter is initialized to 0 after winning the regular bonus, the big bonus (1) or the big bonus (2). However, the gaming state is controlled to the second RT. Then, the process proceeds to step S1019.

  In step S1019, the type of winning combination based on the winning flag set in the winning flag storage register (however, the winning flag is not set in case of losing) and the number of medals to be paid out in accordance with the winning are determined. A winning information command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S406 will be described in detail. FIG. 22 is a flowchart showing in detail the payout process executed by the CPU 111 in step S406. In the payout process, it is determined whether or not there is a small prize winning accompanied by a medal payout depending on whether or not any of the watermelon, bell and cherry winning flags is set in the RAM 112 (step S1101). If the small role is not won, the process proceeds to step S1103.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, the number of credits is increased instead of paying out medals until the number of credits accumulated as data reaches 50 (step S1102). Then, the process proceeds to step S1103.

  Here, it is determined in step S1101 that the small role has not been won, or it is determined that one game has been completed by finishing the medal payout in step S1102. That is, when the small role is won, it is determined that the game is over when the payout of the medal is completed. When the small role is not won, the variable display device 2 displays the medal without paying out the medal. This is the same as determining that the game is over when the result is derived. The operation of the checkout button 16 is effective here, but the operations of the single BET button 14 and the MAXBET button 15 are not yet effective.

  In step S1103, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. If the current gaming state is not a regular bonus, the process proceeds to step S1107. If the current gaming state is a regular bonus, the counter of the RAM 112 is used to count the number of games and the number of winnings in the regular bonus (step S1104).

  As a result of the counting, it is determined whether or not a regular bonus end condition has been met (step S1105). If the regular bonus end condition is satisfied, the regular bonus medium flag in the RAM 112 is deleted. In addition, a counter value for counting the number of games and the number of winnings in the regular bonus is initialized (step S1106). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state. Then, the process proceeds to step S1107. Even if the regular bonus is not terminated, the process proceeds to step S1107.

  In step S1107, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. If the current gaming state is not a big bonus, it is determined whether or not the value of the first RT counter in the RAM 112 is greater than 0 (step S1108). If the value of the first RT counter is larger than 0, the value of the first RT counter is subtracted by 1 (step S1109), and the process proceeds to step S1112. If the value of the first RT counter is 0, it is further determined whether or not the value of the second RT counter is larger than 0 and smaller than 102 (step S1110). If the value of the second RT counter is larger than 0 and smaller than 102, the value of the second RT counter is decremented by 1 (step S1111), and the process proceeds to step S1112. If the value of the second RT counter is 0 or 102, the process proceeds to step S1112 as it is.

  In step S1112, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter, a game state command indicating a game state applied in the next game is generated, Transmit to the control board 102. Then, the process proceeds to step S1124.

  If the current gaming state is a big bonus in step S1107, the number of payout medals in the big bonus is counted using the counter of the RAM 112. The number of payout medals counted here exceeds 465, and it is determined whether or not the big end condition is satisfied (step S1114). If the big bonus end condition is not satisfied, a game indicating a game state applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. A state command is generated and transmitted to the effect control board 102 (step S1115). Then, the process proceeds to step S1124.

  If the big bonus end condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus medium flag is set, it is also deleted. In addition, since there may be a regular bonus in the big bonus that initializes the value of the counter for counting the number of paid-out medals in the big bonus, the value of the counter for counting the number of games and winnings in the regular bonus Is initialized (step S1116). Here, since the value of the first RT counter and the value of the second RT counter are both 0, the gaming state in the next game is the initial gaming state.

  Further, a gaming state command indicating a gaming state (here, always a big bonus) applied in the next game based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the first RT counter and the second RT counter. Is generated and transmitted to the effect control board 102 (step S1117). Here, timing of the wait time is started using the internal timer of the CPU 111 (step S1118).

  When the timing of the wait time is started, it is determined whether or not the value of the credit counter in the RAM 112 is 0 (step S1119). If the value of the credit counter is 0, the process proceeds to step S1123. If the value of the credit counter is not 0, it is determined whether or not an operation of the settlement button 16 is detected by the settlement switch 47 (step S1120). When the operation of the settlement button 16 is detected, the settlement process shown in FIG. 13 is performed (step S1121). Then, the process proceeds to step S1123. In step S1123, it is determined whether or not the time being measured has reached the specified weight time. If the specified time has not been reached, the process returns to step S1119. If the specified time has been reached, the process proceeds to step S1124.

  In step S1124, the winning flag set in the winning flag storage register and the winning flag set in the winning flag storage register are all erased. This process is realized by a process of clearing the general work 112-2 for each game. In this game, the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set and the regular bonus, big bonus (1) or big bonus (2) is not won. Even in such a case, since the value of the special role temporary storage register is not cleared, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over to the next game. On the other hand, since the value of the general combination temporary storage register is always rewritten according to the result of the internal lottery of the next game, the winning combination flag of the general combination is not carried over to the next game.

  Further, when the general work 112-2 is cleared in step S1124, the operation of the single BET button 14 and the MAX BET button 15 is also valid here. Then, the payout process is ended, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 14, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs the transition of the game state among the initial game state, the first RT, the second RT, the big bonus, and the regular bonus, depending on the progress of the game. The command is transmitted to the effect control board 102. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  23 and 24 are flowcharts showing processing executed by the CPU 121 of the effect control board 102. On the effect control board 102 side, it is determined whether or not a command sent from the game control board 101 has been received (step S1201). When any command is received from the game control board 101, it is determined what kind of the received command is (step S1202).

  If the received command type is the winning status notification command transmitted in step S737, the winning status saved in the winning status saving area of the latest game in the previous game (that is, the winning flag in the previous game) Is set in the RAM 122, and the winning status (that is, the setting status of the winning flag in the current game) indicated by the received winning status notification command is provided in the RAM 122. The latest game winning status is saved in the save area (step S1203).

  Next, it is determined whether or not the gaming state stored in the storage area of the latest game in step S1227 of the previous game (that is, the gaming state in the current game) indicates a big bonus or a regular bonus (step S1204). ). If the game state in the current game is not a big bonus or a regular bonus, it is determined whether or not a bonus winning notification has already been made in the previous game (step S1205). If the game state in the current game is a big bonus or a regular bonus in step S1204, or if a bonus winning notification has already been made in step S1205, the process directly returns to step S1201.

  If no bonus winning notification has been made in the previous game, it is determined whether or not the value of the continuous counter in the RAM 122 is 0, that is, whether or not a continuous effect has not yet been executed (step S1206). If the value of the continuous counter is not 0, continuous production has already started, and the process proceeds to step S1210.

  If the value of the continuous counter is 0, it is determined whether or not the gaming state saved in the save area of the latest game in step S1227 of the previous game (that is, the gaming state in the current game) is in the second RT. (Step S1207). If the game state in the current game is the second RT, the stop symbol table in which the stop symbol is stored in step S1212 (described later) in the previous game (at this time, the stop symbol of the previous game has not yet been cleared) ), It is determined whether or not any combination is won in the current game (step S1208).

  If no winning combination has been won in the previous game, 3 is set as an initial value in the continuous counter of the RAM 122 (step S1209). Then, the process proceeds to step S1210. If it is not in the second RT in step S1207, or if any winning combination is won in step S1208, the process returns to step S1201 as it is. In step S1210, in accordance with the value of the continuous counter in the RAM 122, the effect for the current game is started from the continuous effects that are continued in three games. Then, the process returns to step S1201.

  If the received command type is the reel rotation command transmitted in step S904, the information regarding the stop symbols of the reels 3L, 3C, 3R stored in the RAM 122 in the previous game is cleared (step S1211). Then, the process returns to step S1201.

  If the received command type is the reel stop command transmitted in step S916, the symbol is identified by referring to the table of the ROM 123 according to the received reel stop command, and the reel indicated by the reel stop command is stopped. The symbol is stored in the stop symbol table of the RAM 122 (step S1212).

  Next, with reference to the stop symbol table, it is determined whether all of the reels 3L, 3C, 3R are stopped and a chance is derived to the variable display device 2 (step S1213). If the chance is not derived, the process directly returns to step S1201. If the chance is derived, a chance effect indicating the possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) is performed (step S1214). Then, the process returns to step S1201.

  If the received command type is the winning information command transmitted at step S1019, whether the winning information command indicates a regular bonus, a big bonus (1) or a big bonus (2). It is determined whether or not (step S1215). If any one of the regular bonus, the big bonus (1), and the big bonus (2) is shown, it is determined whether or not the value of the continuous counter in the RAM 122 is 0, that is, whether or not the continuous effect is executed. (Step S1216). If the value of the continuous counter is 0, that is, if the continuous effect is not executed, the process proceeds to step S1219.

  If the value of the continuous counter is not 0, that is, if the continuous effect is being executed, the continuous effect being executed is forcibly terminated (step S1217), and the value of the continuous counter is cleared to 0 (step S1218). Then, the process proceeds to step S1219. In step S1219, if a bonus winning notification has been made, this is terminated. Thereafter, by displaying a predetermined image on the liquid crystal display 4, etc., a bonus winning effect indicating a winning of the regular bonus, the big bonus (1) or the big bonus (2) is performed (step S1220). Then, the process returns to step S1201.

  If none of the regular bonus, the big bonus (1), and the big bonus (2) has been won in step S1215, whether or not the value of the continuous counter in the RAM 122 is 0, that is, a continuous effect has been executed. It is determined whether there is any (step S1221). If the value of the continuous counter is 0, that is, if the continuous effect is not executed, the process returns to step S1201 as it is.

  If the value of the continuous counter is not 0, that is, if the continuous effect is being executed, the result of the continuous effect for the current game is shown (step S1222), and the value of the continuous counter in the RAM 122 is decremented by 1 (step S1223). As a result of this subtraction, it is determined whether or not the value of the continuous counter is 0, that is, whether or not the continuous production is to be ended in the current game (step S1224). If the value of the continuous counter is not 0, the process returns to step S1201.

  When the value of the continuous counter becomes 0, it is determined whether or not the winning status stored in the RAM 122 in step S1203 indicates winning of the regular bonus, the big bonus (1), or the big bonus (2). (Step S1225). If any of the regular bonus, the big bonus (1), and the big bonus (2) is not indicated, the process returns to step S1201. If the bonus of regular bonus, big bonus (1) or big bonus (2) is shown, the bonus winning that informs the player of the winning of these roles by displaying a predetermined image on the liquid crystal display 4, etc. Notification is performed (step S1226). Then, the process returns to step S1201.

  When the received command type is the gaming state command transmitted in step S1112, S1115, or S1117, the gaming state stored in the storage area of the gaming state of the latest game in the previous game (that is, the current gaming state command) The game state in the game) is moved to the previous game state storage area provided in the RAM 122, and the game state indicated by the received game state command (that is, the game state in the next game) is stored in the RAM 122. The game state is saved in the save area (step S1227).

  Next, it is determined whether or not the game state of the next game stored in the latest game storage area indicates the initial game state (step S1228). If the game state of the next game is not the initial game state (in this case, the game state of the current game is not a big bonus), the process directly returns to step S1201. If the game state of the next game is the initial game state, for example, an image displayed on the liquid crystal display 4 notifies that the game state of the next game is the initial game state (step S1229). Then, the process proceeds to step S1230.

  In step S1230, it is determined whether or not the big bonus has ended in the current game with reference to the game state for two times stored in the RAM 122. If the big bonus has not ended in the current game, that is, if the game state of the next game is also a big bonus, or if the game state in the current game is not a big bonus, the process returns to step S1201.

  When the big bonus is ended in this game, since the game control board 101 is controlled to be in a frozen state, the display of the image on the liquid crystal display 4, the output of sound from the speakers 7L and 7R, The lighting of all the lamps such as the game effect LEDs 75A to 75M is stopped, and all the effects being executed on the effect control board 102 side are stopped (step S1231).

  Next, timing of the wait time is started using the internal timer of the CPU 121 (step S1232). Then, it is determined whether or not the time being counted has reached the specified wait time (step S1233). If the specified time has not been reached, the process of step S1233 is repeated. If the specified time has been reached, the end of the big bonus is notified by the image displayed on the liquid crystal display 4 and the sound output from the speakers 7L and 7R (step S1234). Then, the process returns to step S1201.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S1235). Thereafter, the process returns to step S1201.

  Note that the specified time (effect side specified time) in step S1233 is set to be shorter than the specified time (game side specified time) in step S1123 of FIG. Since the effect side specified time is set shorter than the game side specified time, the player is notified of the end or continuation of the big bonus while in the freeze state.

  As described above, in the slot machine 1 according to this embodiment, the RAM 112 has the set value work 112-4 for storing the set value and the other work 112 for storing data corresponding to the progress of the game. -1 to 112-3 and the like. The setting value stored in the setting value work 112-4 determines the winning probability of the internal lottery. When the setting value is changed, in the subsequent games, the winning according to the newly set setting value is performed. An internal lottery will be performed with probability.

  In order to change the setting value, the setting machine switch 92 is turned on to start the slot machine 1, and the setting switch 91 is operated in the setting change mode shifted here to select a desired setting value. It is necessary to set the setting key switch 92 to the OFF state after operating. Here, when only the setting key switch 92 is turned on and the data clear switch 95 is turned off, the setting value can be changed, but the other works 112-1 to 112-3 of the RAM 112, etc. Will not be cleared. In order to clear the data of other works 112-1 to 112-3 etc. of the RAM 112, it is necessary to activate not only the setting key switch 92 but also the data clear switch 95 and activate the slot machine 1.

  For this reason, when only the setting value is changed without turning the data clear switch 95 ON, the data relating to other games remains stored in the RAM 112, and therefore, the setting was made before the setting value was changed. The situation in the game (excluding the internal lottery winning probability) is inherited in the game after the set value is changed. For example, the credits and the number of bets accumulated before the setting value is changed are kept as they are, and the gaming state controlled before the setting value is changed continues after the setting value is changed. For this reason, there is no difference before and after the setting value is changed except for the winning probability of the internal lottery.

  Changing the set value only changes the winning probability of the internal lottery, but there is only a difference as a problem of probability, and as long as the number of digest games after changing the set value is small, the winning of the internal lottery The player cannot predict that the probability has changed, that is, that the set value has been changed. Even if the set value can be predicted to some extent depending on the probability of winning an unmissable role such as a bell or replay, a considerable number of games must be completed before reaching that point. For this reason, in situations where multiple slot machines are in operation at the amusement store, the player immediately knows that the set value has been changed between the closing and opening of the previous day. As a result, there is no stand that prevents the player from approaching, and the operating rate of each stand does not decrease.

  On the other hand, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, it is controlled to a RAM abnormality error state and the progress of the game is disabled. In this case, not only the setting value is changed, but also the data clear switch 95 is activated with the setting key switch 92, the data in the RAM 112 is cleared, and a new setting value is set in the subsequent setting change mode. Otherwise, the state where the progress of the game is disabled is not released. Even if the setting key switch 92 is activated with only the ON state, it is controlled again to the RAM abnormal error state before the setting value is changed. The same applies when the number of bets and set values are not appropriate in the internal lottery of each game.

  In this way, when an abnormality occurs in the data stored in the RAM 112, not only the setting value is changed, but a new game cannot be started unless the data in the RAM 112 is cleared. The game is not played based on the above, and the fairness of the game can be achieved. Moreover, if there is an abnormality in the set value and the number of bets, there is a high possibility that fraud is being performed, but since this is determined for each game, the game is performed with unauthorized data. Can be prevented as much as possible.

  However, it is the same in the conventional slot machine that a new game cannot be started unless the data in the RAM 112 is cleared. However, in the conventional slot machine, the setting value is changed and the data in the RAM 112 is cleared by a series of operations. In such a case, the default setting value (usually the setting value 1) is automatically set. It was to be selected and set. For this reason, the winning probability of the internal lottery becomes different from the probability that was intended on the side of the amusement store, and in the setting value 1 that is generally automatically selected, the amusement store inherently sets the setting value 1. There was a problem that the disadvantage of the player would be large except when intended.

  When an abnormality occurs in the data stored in the RAM 112, it is necessary to first clear the data in the RAM 112. In this case, instead of the setting value automatically set by the slot machine 1, a setting change operation is performed. It is guaranteed that the game is played based on the set value selected and set based on the game (generally, since the setting change operation is performed by an amusement store employee, the set value is selected by the amusement store side). Therefore, the fairness of the game can be achieved.

  In addition, the data stored in the RAM 112 is abnormal when the player is not cheated or when the control unit 110 runs out of control, such as when a power failure occurs or the control unit 110 runs out of control. Is almost. In addition to the determination of the setting value and the number of bets that are likely to be determined to be fraudulent, it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from the state in which the control has failed. Therefore, it is possible to determine whether or not the data stored in the RAM 112 is normal only in a situation where there is a high possibility that the data is abnormal. That is, in a situation where there is a low possibility that an abnormality has occurred in the data stored in the RAM 112, it is not necessary to perform the determination, and the load on the control unit 110 can be reduced.

  In particular, in the power interruption interrupt process executed by the input of the voltage drop signal generated when the power is cut off, the RAM parity is calculated based on the data stored in the RAM 112 and stored in the parity storage area 112-7. At the next startup, the RAM parity obtained by the calculation is compared with the RAM parity stored in the parity storage area 112-7 to determine whether the data in the RAM 112 is normal. doing. In this way, it is possible to determine whether or not the data in the RAM 112 is normal only by comparing the RAM parity at the time of input of the voltage drop signal generated when the power is shut off and at the time of startup, so that the determination is performed accurately and simply. Can do.

  In addition to the initial gaming state, the regular bonus, and the big bonus, there are RTs as the gaming state in the slot machine 1 according to this embodiment. There are two types of RTs, a first RT and a second RT. Here, in the first RT, the number of replay judgment values is only 1 in the initial gaming state, and the medal payout rate is almost the same as in the initial gaming state, and is smaller than 1, but the second RT is in the replaying. The winning probability is extremely high compared to the initial gaming state, and the medal payout rate exceeds 1.

  When the watermelon is derived in the initial gaming state, the second RT of 100 games, to the first RT of 1000 games when the bell is derived, and when the cherry is derived, the next regular bonus, big bonus (1) or big bonus ( It is controlled by the second RT until winning 2). However, when it is already controlled to the first RT or the second RT, even if watermelon, bell, or cherry is derived as the display result of the variable display device 2, it is not controlled to a new RT. As described above, since there are a plurality of types of RTs having different degrees of advantage, the progress of the game becomes various, and the interest of the game can be improved.

  Also, depending on whether watermelon, bell, or cherry is derived as the first role to be derived after being controlled to the initial gaming state, there is a difference in the replay winning probability and the number of continuous games in RT, so the initial gaming state In this case, the player can be interested in the display result derived to the variable display device 2, and the interest of the game can be improved. Moreover, in the first RT, the medal payout rate is smaller than 1, and the player's handed medal decreases, but in the second RT, the medal payout rate is larger than 1, and the player's handed medal is Since it will increase, the player's interest in which kind of small role will be derived first after being controlled to the initial gaming state is extremely high.

  In addition, even if there is no regular bonus, big bonus (1) or big bonus (2) after the first gaming state is controlled to the first RT, the first RT is completed after the completion of 1000 games, and the initial game is started again. It will return to the state. Even if there is no regular bonus, big bonus (1), or big bonus (2) after being controlled to the second RT based on the watermelon prize, the second RT will be completed with 100 games and the initial game will start again. It will return to the state. As described above, the first RT or the second RT may return to the initial gaming state again without endlessly, so that the manner in which the gaming state is transitioned is varied, and the interest of the game can be further improved.

  Even if it is controlled to the first RT once, it will return to the initial gaming state by digesting 1000 games, so that if the watermelon or cherry is newly derived here, it can give the player a sense of expectation that it will be controlled to the second RT. . For this reason, even if it is once controlled to the second RT, the player's sense of expectation is not completely lost. Even if the second RT based on the derivation of watermelon is terminated by the digestion of 100 games and returns to the initial gaming state again, if the watermelon or cherry is newly derived here, it is controlled again to the second RT, The player's expectation will not be lost just because the second RT has ended.

  Further, when the bell is won in the initial game state, the first RT is controlled. However, since the bell is not missed at the time of winning, the winning probability is the same as the winning probability. Here, the winning probability of the bell in the initial gaming state is 3370 / 16384≈1 / 4.8. The probability of winning one of watermelon, bell, and cherry is 4087 / 16384≈1 / 4.0 (when the set value is 1). For this reason, since the initial gaming state is expected to be completed in several games, there is no possibility that the game continues in the initial gaming state and the player is irritated.

  The first RT cannot be said to be an advantageous gaming state compared to the initial gaming state because the initial gaming state and the replay winning probability can only be equated, but the second RT has a replay winning probability compared to the initial gaming state. Can be said to be a very advantageous gaming state. Therefore, not only the expectation of whether the first RT or the second RT, but also the expectation that the player wants to leave the initial gaming state and shift to the second RT at an early stage can be given to the player. be able to.

  In addition, the advantage of the controlled RT varies depending on the type of the small role derived first after being controlled to the initial gaming state, but the next game is played in the initial gaming state. When it becomes, it will be notified to the player to that effect. Therefore, the variable display device can be used when there is no possibility that the player has been controlled from the initial gaming state to RT (first RT or second RT) without being noticed, and there is a possibility that the player will be newly controlled by RT. It becomes possible to attract the player's interest in the display result derived to 2.

  Also, the role that triggers the control of the gaming state from the initial gaming state to the RT (first RT or second RT) is a small role of watermelon, bell, cherry, and a separate role for controlling the gaming state to RT is provided separately There is no need. For this reason, the types of winning combinations can be suppressed to a certain type, and the game in the slot machine 1 is not complicated. Further, since the types of winning combinations are not increased, the internal lottery process and the reel 3L, 3C, 3R stop control are not complicated.

  Furthermore, the bell that will be controlled to the first RT whose medal payout rate is smaller than 1 is a role that will be won without missing if it is won by internal lottery, but the medal payout rate Even if the watermelon and cherry to be controlled to the second RT larger than 1 are won by the internal lottery, depending on the operation timing of the stop buttons 12L, 12C, and 12R, it is a role that causes the loss. Thus, in order to control the second RT, which is advantageous to the player, it is necessary for the player to intervene in the technology, so that the player's profits differ depending on the skill, and the game's interest is further improved. Can be made.

  Even after being controlled to the first RT by deriving the bell, if the regular bonus, the big bonus (1) or the big bonus (2) is won, the second RT is controlled. If no winning combination is won in 2RT, continuous production over three games will be started. Even when the display result of losing is derived without winning any of the roles, the player can feel the expectation of the player by starting the continuous production, and the interest of the game can be improved. .

  Here, if the regular bonus, the big bonus (1), or the big bonus (2) is won when the continuous effects over the three games are finished, a bonus winning notification is performed. In this way, the continuous production is a game that makes the player expect the winning of the regular bonus, the big bonus (1) or the big bonus (2) from the game before the result is shown, and has a very high production effect. As a result, the interest of the game can be improved.

  The continuous performance is an effect that makes the player expect the regular bonus, the big bonus (1), or the big bonus (2) to be won, but even if these roles are won in the first RT, the game state in the second RT The continuous production is started after is controlled. The second RT has a very high replay winning probability, and even when the regular bonus, big bonus (1), or big bonus (2) is also won, the replay is given priority and the start of continuous production From the end of the game to the end, the player's expectation can be raised without winning the regular bonus, the big bonus (1) or the big bonus (2) as much as possible.

  Furthermore, although it is stipulated that none of the roles has been won as an opportunity to start the continuous production, regular bonus, big bonus (1) or big bonus ( Since the winning of 2) is not possible, it will not be known that the regular bonus, the big bonus (1) or the big bonus (2) is not won in the game where the continuous production is started, and the production is meaningless It can be made not to let it be. On the other hand, the fact that he did not win any role in the 2nd RT, which has a very high replay win probability, means that he may have won the regular bonus, big bonus (1) or big bonus (2). Therefore, the player can be expected to win the regular bonus, the big bonus (1), or the big bonus (2) without discouraging the player.

  If the chance is derived as the display result of the variable display device 2, it means that the regular bonus, the big bonus (1) or the big bonus (2) may be won. In this case, the liquid crystal display Chance production is also performed in the vessel 4. For this reason, even if the beginner is relatively unfamiliar with the game and cannot determine whether the display result of the variable display device 2 is a chance, the regular bonus, the big bonus (1), or the big bonus (2) You will be able to know for sure that you may have won.

  By the way, the big bonus ends when the number of medals paid out exceeds 465, regardless of the number of digest games. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for terminating the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

  Further, when the gaming state is controlled to the big bonus, if the regular bonus medium flag is not set in the RAM 112 when the start lever 11 is operated, the regular bonus medium flag is newly set at this time, and the gaming state Is controlled to a regular bonus. Thus, the big bonus can be provided by repeating the regular bonus until the number of payout medals reaches the specified number, and the player can obtain the maximum profit in the big bonus. Moreover, even when the regular bonus is controlled for the first time after winning the big bonus (1) or the big bonus (2), the regular bonus is controlled again when the regular bonus has been completed and the big bonus has not yet ended. In this case, the same processing is performed.

  In addition, all the reels rotate among a plurality of stop control tables in which stop positions (display results) are uniquely determined with respect to stop operation positions (areas assigned to the number of steps from the reel reference position). In the middle, a stop control table uniquely determined for the internal winning state for each gaming state is selected, and reel stop control is performed according to the selected stop control table. On the other hand, if any of the reels has already stopped, select a stop control table uniquely defined for the internal winning state for each gaming state, the stop position of the stopped reel, The reel stop control is performed according to the selected stop control table, and all of the gaming state, the internal winning state, and the reel stop state (and the stop position of the stopped reel (display result)) are the same condition. When this happens, reel stop control is performed based on the same stop control table, that is, the same control pattern. Therefore, as in the prior art, one stop control table is further selected from a plurality of stop control tables for one internal winning state by a lottery different from the internal lottery (for example, a lottery lottery for reel control, etc.). This is unnecessary, and the control for stopping the reel does not become complicated.

  As described above, the storage address of the judgment value number of each lottery target role registered in the role-specific table for each gaming state may differ depending on the set value, but regardless of the set value. For the combination having the same winning probability, the number of determination values is stored in common regardless of the set value. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. However, in the role-specific table, even if the target number of the internal lottery is the same as the number of bets set and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

  In general, in the development stage, the simulation is performed while adjusting the number of determination values according to the set values for at least some of the combinations (that is, adjusting the winning probability of internal lottery). As the initial number of determination values, a different number of determination values is registered according to the set value. However, as a result of adjustment by simulation, the number of determination values when the set values are different may be the same. Although the same number of judgment values was registered as the initial number of judgment values according to the set value, the number of judgment values registered from the beginning may be used as it is depending on the result of simulation (result of simulation). The number of judgment values different from the initial value, that is, the number of judgment values may differ depending on the set value). Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set for the mass production model.

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the determination value number is stored in the ROM 113 by the same address assignment as the address assignment in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. It should be noted that when the winning determination table is generated before the actual winning determination is made, the loop processing is required twice, but according to this embodiment, the loop processing in the lottery processing is only required once. Thus, the processing efficiency in the entire lottery process is high.

  In addition, in the initial gaming state or RT, the number of determination values includes those for which both regular bonus, big bonus (1), big bonus (2) and cherry are subject to lottery. Here, if none of the regular bonus winning flag, big bonus (1) winning flag, and big bonus (2) winning flag has been carried over from the previous game, depending on the value of the random number for internal lottery, Both the big bonus (1) or the big bonus (2) and the cherry are won.

  Here, even if the winning of the cherry is won based on the display result of the variable display device 2 based on the cherry winning flag set based on the winning of the cherry which is one of the lottery objects, the regular bonus winning flag, the big bonus There is a possibility that either (1) a winning flag or a big bonus (2) a winning flag is set. For this reason, even when winning the cherry, the player can be expected to win the regular bonus, the big bonus (1), or the big bonus (2), and the fun of the game can be improved.

  Even if the cherry winning flag is set, the cherry may be missed depending on the operation timing of the stop button 12L, and the payout number of medals is relatively small, but if you win in the initial gaming state, the next regular This is a role for controlling the gaming state to the second RT until a bonus, a big bonus (1) or a big bonus (2) is won. In addition, the winning of the regular bonus, the big bonus (1) or the big bonus (2) can be expected by winning. Thus, even if the number of medals to be paid out is small, it is possible to further improve the interest of the game by providing a small role with a great expectation given to the player.

  In addition, in order to check whether or not an illegal winning of a combination for which no winning flag is set has occurred, a winning flag storing register having the same form as the winning flag storing register is prepared, and the winning display line on the variable display device 2 is provided. A winning flag corresponding to a combination of symbols is set. Then, after logically inverting the data in the winning flag storage register, the logical product operation is performed for each bit of the data in the winning flag storage register. As a result, it is not necessary to individually compare the winning flag and the derived display result, and it is possible to easily determine the illegal winning.

  Here, since the contents of the winning flag storage register are rewritten by logically inverting the data of the winning flag storage register in order to make an illegal winning determination, the winning flag storage register is provided in the general work 112-2. The data is cleared for each game, that is, all winning flags are erased for each game. Of course, although it is also used for selection of reel control, the winning of the regular bonus, the big bonus (1) or the big bonus (2) is written in the special combination temporary storage register which is not updated until the winning. As a result, the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag can be carried over until winning.

  Moreover, instead of deleting only the winning flags other than the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag for each game, the general work 112-2 including the entire winning flag storage register. Is cleared for each game. For this reason, it is not necessary to prepare a winning flag storage register across the general work 112-2 of the RAM 112 and other works, and the position of the winning flag storage register at the time of design is improved. In addition, since it is not necessary to delete only the replay or small winning combination flag in units of bits, the processing becomes easy.

  The random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 115 by the sampling circuit 116 but is used after being processed by software. The random number generation circuit 115 generates a random number by updating at a high speed with the frequency of the pulse signal of the pulse generation circuit 115a. However, in the random number for internal lottery processed by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, by sequentially adding the number of determination values corresponding to each combination to the value of the random number for internal lottery, the value of the random number for internal lottery winning each combination is It will harden. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 115a to update the values of the counters 115b and 115c of the random number generation circuit 115 is higher than the frequency of the operation clock of the CPU 111, and is not an integral multiple. For this reason, the update of the random number generated by the random number generation circuit 115 becomes difficult to synchronize with the processing performed by the CPU 111. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 115a, the update speed of the random number generated by the random number generation circuit 115 can be made extremely fast.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 115 by the sampling circuit 116, masking the 15th and 7th bits, and then bit-shifting the upper byte. Good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  By the way, each game in the slot machine 1 is started when the control is shifted to start the rotation of the reels 3L, 3C, 3R by the operation of the start lever 11, and is the display result derived to the variable display device 2? When the small combination is won according to the display result, the process ends when the medal payout is completed. During the period from the start to the end of the game, setting of the number of bets and the settlement of credits are prohibited. Here, the freeze state when the big bonus ends is controlled after it is determined that one game has ended.

  In the frozen state, the progress of the game is disabled, so the setting of the number of bets remains prohibited. However, the credit settlement is canceled when it is determined that the game has ended before being controlled to the frozen state. Has become. For this reason, even if the bet number setting is prohibited due to the controlled freezing state, it is possible for the player to settle the credit, so that the player's will is reflected as much as possible. A medal can be paid out according to the credit stored as the medal owned by the user.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the operation of clearing the data in the RAM 112 is to turn on the data clear switch 95 when the setting key switch 92 is turned on to start the operation. Some operations were common to the change. On the other hand, the data in the RAM 112 may be cleared by an operation completely different from the operation of changing the set value. Further, by performing different operations on the same operation means, it may be possible to simply perform a setting value change operation and clear data in the RAM 112. In any case, the operation for clearing the data in the RAM 112 may not be completely the same as the operation for changing only the set value.

  In the above embodiment, when the data in the RAM 112 is cleared in step S111, only the data of the set value work 112-4 is not cleared. Of course, when the data in the RAM 112 is cleared, the setting value stored in the setting value work 112-4 may be set as an initial value (for example, 1), and subsequently, the setting value changing mode may be entered.

  In the above embodiment, the cherries have been defined as the possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) at the same time in one game. It may be a small role or a replay. When there are a plurality of types of replay roles, one of them can be a regular bonus, a big bonus (1), or a big bonus (2) that can be won simultaneously in one game. Furthermore, a role that may be won simultaneously in one game with a regular bonus, a big bonus (1), or a big bonus (2) controls the gaming state to the RT without paying out medals or granting a replay. It is also possible to serve only.

  In the embodiment described above, when determining an illegal winning, the data of each bit of the winning flag storage register is logically inverted, and the logical product operation is performed on the data of each bit of the winning flag storage register. On the other hand, the data of each bit of the winning flag storage register may be logically inverted, and this and the data of each bit of the winning flag storage register may be ORed. In this case, if the calculation result is 1, there is no illegal prize, and if it is 0, an illegal prize has occurred. Note that these operations can be appropriately changed depending on whether the bit indicating winning or winning is set to 0 or 1 or using positive logic or negative logic for the operation.

  In the above embodiment, the continuous production is only performed according to the number of games from the start, and the production has different contents depending on the winning status of the regular bonus, the big bonus (1) or the big bonus (2). It never became. On the other hand, when starting the continuous production, the production pattern selected according to the winning situation of the regular bonus, the big bonus (1) or the big bonus (2) is selected, and the continuous production is performed according to the selected production pattern. It is good also as what produces each game in the period which should be performed, and alert | reports the presence or absence of a bonus winning at the end.

  In this case, a new regular bonus, big bonus (1), or big bonus (2) may be won in the game after the continuous production is started. In this case, after notifying the bonus non-winning in the first selected pattern, the bonus effect can be notified again by executing an additional effect. Further, a part of the selected pattern, for example, the contents of the effect in the last game of the continuous effect can be replaced. Execution of the additional effect and replacement of the content of the effect may be used together, and one of them may be selected. Whether the regular bonus, the big bonus (1) or the big bonus (2) is newly won in the game after the continuous production is started is determined by each game during the continuous production. However, it may be determined after the internal lottery ends in the game where the continuous performance ends.

  In the above embodiment, the continuous production is started when the display result of the loss is derived to the variable display device 2 in the second RT. However, the continuous performance is to finally notify the winning of the regular bonus, the big bonus (1), or the big bonus (2), and makes the player expect the winning of these roles. Therefore, when the regular bonus, the big bonus (1) or the big bonus (2) is won in the internal lottery, or when all the combinations are lost, the continuous production may be started.

  In the above embodiment, when a game state command is received at the end of one game, an initial notification is made based on this. Therefore, in the first game after the data in the RAM 112 is cleared, the player is not notified that the game is performed in the initial game state although the game is controlled in the initial game state. Therefore, a game state command may be transmitted from the game control board 101 to the effect control board 102 at the start of one game, and based on this, an initial notification may be made at the start of one game.

  Furthermore, the initial notification indicating that such a gaming state is controlled to the initial gaming state may not be performed at all. Here, the first RT has no difference in replay winning probability that can be distinguished from the initial gaming state. For this reason, even if it is actually controlled by the first RT, the player can be expected to be controlled in the initial gaming state that may be controlled by the second RT.

  In the above embodiment, when the regular bonus, the big bonus (1) or the big bonus (2) is won while being controlled by the first RT, the first RT is terminated and the gaming state is controlled by the second RT. I was supposed to do. However, in such a case, although the first RT is terminated, the gaming state may be controlled to the initial gaming state instead of the second RT.

Further, when a predetermined special combination other than the regular bonus, the big bonus (1) and the big bonus (2) described above is provided and a predetermined special combination is won in the first RT or the second RT, the predetermined special combination is determined from the first RT or the second RT. The gaming state is controlled to a predetermined gaming state (for example, a bonus with a smaller expected value of the number of paid-out medals than a regular bonus or a big bonus, such as a bonus that lasts for one game or two games). After the gaming state is ended, the gaming state may be controlled to the initial gaming state. The predetermined special role may not be missed when winning. Even if there is no missing case, the first RT or the second RT may be terminated when a predetermined special role is won.
Here, it is preferable that the winning probability of the predetermined special role is smaller than the reciprocal of the number of continuing games of the second RT based on the derivation of watermelon (that is, 1/100).

  In this way, even after being controlled to the first RT or the second RT according to the type of the small role first derived in the initial gaming state, when the predetermined special role is won, the gaming state is controlled to the initial gaming state again. It has become. For this reason, since it is controlled to any type of RT and before the regular bonus, big bonus (1) or big bonus (2) is won, it may be controlled to a different type of RT. The progress mode of the game becomes abundant and the interest of the game can be further improved. Further, if the winning probability of a predetermined special role is made smaller than the reciprocal number of the second RT continuous game, it is advantageous for the player while avoiding frequent occurrence of the second RT puncture which is highly advantageous for the player. It can be said that the player's expectation is maintained even after the first RT is controlled to a low degree.

  Further, the RT that is terminated by a predetermined special combination may be only the first RT having a low advantage for the player. In this case, the winning probability of the predetermined special combination may be higher or lower than the reciprocal of the number of continuing games of the second RT based on the derivation of watermelon (that is, 1/100). In this case, even when the gaming state is in the first RT, the game is controlled to the initial gaming state after passing through the predetermined gaming state by winning a predetermined special role, and further, the first small role winning type there Accordingly, the player can be given a sense of expectation of being controlled by the second RT, and the interest of the game can be improved.

  In the above-described embodiment, the number of replay determination values in the first RT is one greater than the number of replay determination values in the initial gaming state, and the replay winning probability in the first RT is very small but the replay winning probability in the initial gaming state is very small. Was supposed to be higher than. However, the replay determination value number in the first RT may be smaller than the replay determination value number in the initial gaming state, and the replay winning probability in the first RT may be lower than the replay winning probability in the initial gaming state.

  In the above embodiment, the gaming state is controlled to the first RT or the second RT according to the type of the small role derived first in the initial gaming state, and the replay is derived in the initial gaming state. However, the first gaming state is not controlled by the first RT or the second RT. However, when the replay is derived in the initial gaming state, the gaming state may be controlled to either the first RT or the second RT (the one determined in advance corresponding to the replay). In addition, two types of replay A (for example, JAC-JAC-JAC) and Replay B (JAC-JAC-Bell) are prepared as replaying roles (each of which is separately subject to internal lottery), and in the initial gaming state When the replay A is first derived, the gaming state may be controlled by the first RT, and when the replay B is derived, the gaming state may be controlled by the second RT.

  In this way, when the gaming state is controlled to the first RT or the second RT by derivation of the replay, the winning probability of the initial gaming state A and the role to shift the gaming state to the second RT is higher (other roles ) And the initial gaming state B may be provided. When there are two types of replays, Replay A for shifting the gaming state to the first RT and Replay B for shifting the gaming state to the second RT, the first RT and the second RT are the same for the winning combination of the small role, Assuming that the game is not shifted to any of the above, (the winning probability of Replay B / the winning probability of Replay A) may be higher in the initial gaming state B than in the initial gaming state A.

  Here, in order to increase (winning probability of Replay B / winning probability of Replay A) in the initial gaming state B from the initial gaming state A, the winning probability as a whole replay is the same, but the winning probability of Replay B is Even if it is higher in the initial gaming state B than in the initial gaming state A, the winning probability of Replay A is the same, but the winning probability of Replay B may be higher in the initial gaming state B. That is, the initial gaming state B can be a chance RT that has a higher probability of shifting to the second RT than the initial gaming state A.

  When there are two types of initial game states A and B in this way, for example, the game state is controlled to the initial game state A after the regular bonus ends, and the game is moved to the initial game state B after the big bonus ends. It is good also as what controls a state. In addition, when the first RT is completed due to the digestion of the prescribed number of games, the gaming state can be controlled to the initial gaming state A. It should be noted that the gaming state can be controlled to the initial gaming state A after the setting value changing operation is completed after clearing the data in the RAM 112.

  As described above, the gaming state is controlled to the initial gaming state A after the end of the regular bonus, but after the big bonus is finished, the gaming state is controlled to the initial gaming state B where the medal payout rate easily exceeds the second RT. By doing so, the player can often receive the next bonus (regular bonus or big bonus) without reducing the medals on hand after the end of the big bonus. Thereby, the player's expectation for the big bonus can be further increased, and the interest of the game can be improved. Even when a bonus announcement is made, the player's interest in the type of bonus that has been won can be further increased.

  On the other hand, the initial gaming state B after the regular bonus has ended may be shifted to the second RT, so the player's expectation will not be reduced just because the regular bonus has been reached. Furthermore, the player's expectation for the big bonus can be further enhanced by controlling to the initial gaming state A instead of the initial gaming state B after the first RT is ended by digestion of the prescribed number of games. The interest of the game can be improved. Since the initial gaming state controlled after the RAM 112 data is cleared and the setting value changing operation is completed is the initial gaming state A, the initial gaming state B having a high probability of shifting to the second RT is associated with the big bonus. Thus, it is possible to achieve a special initial gaming state, to further increase the player's expectation for the big bonus, and to improve the interest of the game.

  Furthermore, the display mode for shifting the game state from the initial game state to the first RT or the second RT does not necessarily have to be a display mode of a winning combination such as a replay or a small role. It is good also as a predetermined display mode among the display modes of the losing that is derived by the operating procedure of the stop buttons 12L, 12C, 12R even when all the roles are lost in the internal lottery or even if any winning combination is won. .

  In the above embodiment, the gaming state is controlled to the first RT when winning a bell in the initial gaming state, and the gaming state is controlled to the second RT when winning a watermelon or cherry. In the second RT, the winning probability of a role other than replay is the same as that of the first RT, but the replay winning probability is higher than that of the first RT, so that the gaming state is more advantageous for the player than the first RT. However, the gaming status controlled when winning a watermelon or cherry is the same as the gaming status controlled when winning a bell, but the winning probability of each role is the same. Announce the operation procedure of the stop buttons 12L, 12C, 12R for winning (the player determines the operation timing of the stop buttons 12L, 12C, 12R to enter the winning combination by announcing the type of winning combination itself) It may be in a gaming state (so-called AT) that can be recognized, or that informs the operation sequence of the stop buttons 12L, 12C, and 12R in which a winning combination can be won or facilitated. AR which combined RT and AT may be sufficient.

  In the above embodiment, at the end of the big bonus, the freeze effect is controlled such that the progress of the game is disabled for a certain period of time and all the effects are stopped. It may be performed at the start of the game, that is, immediately after winning the big bonus (1) or the big bonus (2). Even when the freezing effect is performed at the start of the big bonus, only the settlement of credits can be performed as in the case of performing the freezing effect at the end of the big bonus. Furthermore, it is also possible to perform stop control that disables the progress of the game until a predetermined operation (such as a reset operation) is performed after the big bonus has ended. Even when the stop control is performed, only the credit settlement can be performed as in the case where the freeze effect is performed.

  In the above embodiment, when some of the three reels 3L, 3C, 3R are already stopped, the internal winning state for each gaming state and the stop position of the stopped reel are unique. A stop control table that is determined in a specific manner is selected, and reel stop control is performed in accordance with the selected stop control table. Here, instead of the stop position of the stopped reel, the position when the stop buttons 12L, 12C, and 12R are operated to stop the reel (that is, the number of steps of the reel) may be applied. Good. Also in this case, similarly to the selection of the stop control table in the above embodiment, it is possible to obtain an effect that the control for stopping the reel does not become complicated.

  In the above embodiment, the number of determination values stored in the address registered in the role-specific table is added to the random number for internal lottery, and when an overflow occurs as a result of the addition, the winning combination is won. I was supposed to. On the other hand, the acquired number of determination values may be sequentially subtracted from the acquired internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  In the above embodiment, the internal lottery sequentially adds the number of judgment values of each combination according to the game situation to the acquired random value for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 115 is replaced with the low-order byte, and the whole low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 115 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. Alternatively, the random number value extracted from the random number generation circuit 115 may be directly acquired as a random number for internal lottery. Furthermore, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 115, that is, the random number extracted by the hardware random number function is processed by software has been described. However, the random number processing by the software described above may be applied to a random number that is periodically updated by software. For example, the microcomputer constituting the control unit 110 is an I / O port that causes the CPU 111 to send an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in the first microcomputer. It can be input to the CPU 111 via 114 and stored in the general-purpose register 111GR. The function of the second microcomputer may be included in the microcomputer constituting the control unit 110. Also in this case, the random number value obtained after processing can be varied, and the effect of preventing the player from aiming can be achieved.

  In the above embodiment, the determination value number storage area uses a 2-byte area to store the determination value number in each case. However, in a general slot machine, the number of judgment values for a combination such as a regular bonus, a big bonus (1), or a big bonus (2) may be set to exceed 255 in any gaming situation. Absent. Thus, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  In the above embodiment, the number of determination values is stored in common for all of the setting values 1 to 6 or individually stored for each of the setting values 1 to 6. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common.

  In the above embodiment, in the initial gaming state, the first RT or the second RT, the game can be started only by setting 3 as the bet number. On the other hand, even in the initial gaming state, the first RT or the second RT, the game can be started by setting 1 as the bet number, and further, the game can be started by setting 2 as the bet number. You may be able to do that.

  In the initial gaming state, when 1 or 2 is set as the bet number in the first RT and the second RT, the winning probability of the small role in the internal lottery is lowered and smaller than the case where 3 is set as the bet number. It is possible to increase the number of medals to be paid out when winning. In addition, in a slot machine in which any of 1, 2, or 3 can be set as the number of bets in the initial gaming state, the first RT and the second RT, the number of determination values is stored in common for all of the setting values 1 to 6. In addition, there may be a combination that is stored in common for all bets 1 to 3. In this case, the storage area for the number of determination values can be reduced according to the number of bets, and the storage capacity can be further reduced.

  In the above embodiment, in the game in which the gaming state is the big bonus and the big bonus medium flag (the big bonus (1) medium flag or the big bonus (2) medium flag) is set in the RAM 112, the operation of the start lever 11 is performed. It is sometimes determined whether or not the regular bonus medium flag is set in the RAM 112, and if the regular bonus medium flag is not set, it is set and controlled to the regular bonus. Even when the regular bonus is controlled first after the big bonus (1) or the big bonus (2) is won, the regular bonus is controlled again when the regular bonus for one time is finished and the big bonus is not finished yet. Even in this case, the same processing should be performed.

  On the other hand, when the big bonus (1) or the big bonus (2) is won, a regular bonus medium flag is set in the RAM 112 together with the big bonus medium flag, and when the regular bonus end condition is established in the big bonus, Clear regular bonus medium flag. Here, when the regular bonus medium flag is deleted, if it is determined that the big bonus end condition is not satisfied and the big bonus medium flag is set in the RAM 112, the regular bonus medium is again set. The flag may be set in the RAM 112 and controlled to a new regular bonus as it is. In this case, when the big bonus is controlled by winning the big bonus (1) or the big bonus (2), it can be controlled to the regular bonus at the same time. When the bonus is not finished, you can immediately return to the regular bonus.

  The game state of the big bonus provides a small role game by winning the big bonus (1) or the big bonus (2), and further, JACIN (for example, “Replay-Replay-” based on the JACIN winning in the small role game. It is also possible to provide a regular bonus among the big bonuses in the gaming state by winning a prize in an internal lottery during a small role game in “JAC”. If the regular bonus for one set is completed during the big bonus and the number of payout medals has not exceeded 465, it can be controlled again as a small role game.

  In the above embodiment, the reel control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the reel control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to be aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn. If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When game balls are used as game media, for example, one medal can correspond to five game balls, and when three bets are set in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.
