Description

  The present invention relates to a slot machine, and more particularly, to processing related to determination of whether or not derivation of a winning display result is allowed.

  In general, a slot machine generally has a plurality of types of symbols such as “red 7”, “white 7”, “BAR”, “watermelon”, “bell”, “cherry”, “JAC” drawn on the outer periphery. A variable display device having three (usually three) reels is provided, and each reel starts to rotate when the player operates the start lever, and the player is provided corresponding to each reel. The rotation is stopped by operating the stop button. Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  The types of winning combinations include small roles with payout of medals, replay roles that allow the next game to be started without setting the number of bets, and transition to a gaming state that is advantageous to the player such as regular bonuses and big bonuses. There is a bonus role with. Among these roles, the small role and the replay role can only be profitable by the player for only one game, but the bonus role can be profitable by the player over the subsequent several games. Therefore, it is a role with high expectations for the player.

  Which display mode is derived for each combination is determined according to the gaming state, and in order for any combination to win, before the display result is derived It is necessary to win the internal lottery performed in advance and set the corresponding winning flag. In addition, whether or not the winning flag is set does not depend only on whether or not the winning display mode is derived. Losing eyes may be derived on the condition that no winning flag is set.

  By the way, the winning flag for a small role or a replay role is erased only for the game regardless of whether or not a prize has been won, but the winning flag for a bonus role is generally carried over from the next game until a winning occurs. It is. Therefore, in some cases, the winning combination of the bonus combination is carried over to the small combination or the replay combination, and the winning flag of the small combination or the replay combination may be set redundantly. However, in the internal lottery in the conventional slot machine, only one combination is won for one game (for example, see Patent Document 1).

  In addition, the winning probability of each combination in the internal lottery is not completely fixed for each slot machine, and can be changed by selecting any one of the setting values from, for example, six levels. (For example, refer to Patent Document 1). The setting value is selected by a store clerk at the amusement store, and the selected setting value may be stored in the RAM inside the slot machine. However, the data in the RAM including the setting value may be damaged for some reason. is there. If the data in the RAM remains broken, a normal game cannot be performed. In such a case, the progress of the game is once disabled.

Japanese Patent No. 3474804 (paragraphs 0035 to 0040, Table 2)

  As described above, in the internal lottery in the conventional slot machine, only one combination is won per game. Therefore, for example, if a small role is won in the current game after the losing eye has been derived in the previous game, it will be understood that the bonus role cannot be won here. For this reason, it becomes impossible to make the player expect more profit than the profit obtained by winning the small role.

  In addition, the state in which the game cannot be progressed because the data in the RAM is broken is released after the data in the RAM is initialized by a predetermined reset operation, and the progress of the game is resumed. ing. Here, when data in the RAM is initialized by a reset operation, a default value (usually, setting 1 with the lowest winning probability) is automatically selected as a setting value. For this reason, the internal lottery may not be performed with the probability that the game store intended, and in particular when the setting 1 is automatically selected, the disadvantage of the player is increased. was there.

  The present invention can give a player a sense of expectation that the derivation of the special display result accompanying the transition of the gaming state is allowed even in a game in which the derivation of the general winning display result other than the special display result is allowed. The purpose is to provide a slot machine.

  The present invention also provides a slot machine that always determines with a proper probability whether or not to allow the derivation of a winning display result including a special displaying result and a general winning display result other than the special displaying result.

Range determining means for determining to be included in the range of the determination value specified by the specified range specifying data,
It is determined whether or not the derivation of the plurality of types of winning display results is allowed according to the determination result of the range determination means, and the determination numerical data input to the determination area is specified by the overlapping range specifying data. When it is determined by the range determination means that the value is included in the range of the determination value, it is determined that the derivation of both the special display result and the general winning display result is permitted (steps S514 and S518).
It is characterized by that.
Instead of the adding means and the range determining means, the prior determining means
Data indicating the number of determination values respectively indicated by a plurality of range specifying data stored in the range specifying data storage means corresponding to the types of allowable steps set by the allowable step setting means, sequentially, in the determination area Subtracting means for subtracting from the numerical value data for determination input to, and when the subtraction result of the subtracting means exceeds the predetermined range, the numerical value data for determination input to the determination area Range determination means for determining that the data indicating the number of determination values when exceeding the range of the determination value specified by the range specifying data targeted for subtraction may be included.

  In the slot machine, when the numeric data for judgment input in the judgment area is included in the judgment value range specified by the overlapping range specification data, both the special display result and the general winning display result are derived. It will be decided to allow this. In this case, even if the general winning display result is derived as the display result of the variable display device based on the determination that the deriving of the general winning display result is one of the determinations, the special display result is allowed to be further derived. It may be decided to do so. As a result, the player's sense of expectation for the derivation of the special display result can be increased, and the interest of the game can be improved.

  Further, when the data stored in the data storage means is not normal, the game cannot be progressed properly because the game cannot be progressed properly. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the game cannot be progressed here. In this case, the data indicating the allowable stage is also initialized. End up. However, in the slot machine, the state in which the game cannot be progressed based on the data in the data storage means being normal is canceled unless a new allowable stage is set based on the operation of the setting operation means. There is nothing. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

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 RAM 112 uses a DRAM (Dynamic RAM), and requires a refresh operation to maintain the stored data contents. The CPU 111 is provided with a refresh register for performing this refresh operation. The refresh register is composed of 8 bits, which is the size of one word, and the lower 7 bits are automatically incremented every time the CPU 111 fetches an instruction from the ROM 113, and the value is updated by 1 instruction. It is performed at every execution time. The configuration of the RAM 112 area will be described later.

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 circuit 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. Each of these commands consists of 8 bits. 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.

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 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. 3 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 An area for setting a winning combination flag to be described later is provided in the general work 112-2. 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. Hereinafter, a setting value changing operation using 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. Then, when the setting key switch 92 is turned off, the state shifts to a state in which the game can proceed.

  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) is determined. When the set value is within the normal range, it is determined that the RAM is abnormal, and a RAM abnormal error code is set and controlled to a RAM abnormal error state to disable the progress of the game.

  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).

  When the control unit 110 of the game control board 101 is activated, the RAM parity is calculated based on all data other than the data stored in the parity storage area 112-7 among the data stored in the RAM 112. Compared with the RAM parity stored in the parity storage area 112-7. If the comparison results match, the state before power-off is restored based on the state stored in the RAM 112.

  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. Unlike the other error states, the RAM abnormal error state is not canceled even if the first reset switch 48 or the second reset switch 93 is operated, and a new set value is set in the setting change mode. It comes to be canceled by this.

  In the slot machine 1, a winning is awarded when the symbols are arranged on the active line set according to the betting number 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 that involve the transition of gaming status, small roles that involve the payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. In order for each winning combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag for the winning combination.

  FIG. 4A 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. In this case, the combination determined as the lottery target is shown. As for the role in this slot machine 1, regular bonus, big bonus (1), big bonus (2), JACIN as special roles, cherry, JAC, watermelon, bell as small roles, and replay as replaying roles are determined. ing.

  In addition, for cherry and watermelon, a regular bonus, a big bonus (1), or a big bonus (2) and an internal lottery may be used simultaneously for lottery. However, the regular bonus, the big bonus (1), and the big bonus (2) are won at the same time as other roles due to the relationship between the symbol arrangement on the reels 3L, 3C, and 3R and the stop symbols registered in the reel control table. There is no.

  In the regular bonus game state, small roles such as cherry, JAC, watermelon and bell are defined as winning combinations. In the game state of the big bonus, the regular bonus and JACIN which are special roles and the cherry, watermelon and bell which are small roles are determined as winning roles. In a normal gaming state, regular bonuses and big bonuses that are special roles, cherry, watermelon and bell that are small roles, and replay that is a re-playing role are determined as winning roles.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is arranged on any of the active lines (five) in the normal gaming state, the RT or the small role game in the big bonus. When the regular bonus is won, the gaming state shifts from the normal 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. While the gaming state is in the regular bonus, the 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 comes in either the red 7-red 7-red 7 combination or the white 7-white 7-white 7 combination on the active line (5) in the normal gaming state or RT. Sometimes wins. When the big bonus is won, the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. 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. In the following description, when it is necessary to distinguish between the big bonus by “Red 7-Red 7-Red 7” and the big bonus by “White 7-White 7-White 7”, the big bonus (1), It shall be called a big bonus (2).

  JACIN is awarded when a combination of “watermelon-JAC-JAC” is placed on any of the active lines (5) in the small role game in the big bonus, but in a game state other than the small role game, Even if the combination is complete, JACIN won't win. When winning JACIN, the above-mentioned regular bonus is provided in the big bonus, and the regular bonus medium flag is also set in the RAM 112 in addition to the big bonus medium flag. When the regular bonus in the big bonus exceeds the above-mentioned 465, the regular bonus is terminated together with the big bonus.

  JAC is awarded when the combination of “Bell-JAC-JAC” is aligned on the active line (1 line) in the regular bonus, but in a gaming state other than the regular bonus, even if this combination is aligned, Don't be. A watermelon is awarded when the combination of “watermelon-watermelon-watermelon” is aligned on any of the active lines (one or five) in any gaming state. A bell is awarded when the combination of “bell-bell-bell” is aligned on any of the active lines (one or five) in any gaming state. Cherry is awarded when the symbol “cherry” is derived on one of the active lines (one or five) for the left reel 3L in any gaming state.

  Replays are awarded when a combination of “JAC-JAC-JAC” is placed on either of the active lines (5) in normal gaming state or RT, but regular bonuses and big bonuses (small game and regular bonus) Bonus) will not win a replay even if this combination is available. When a replay is won, no medals will be paid out, but the next game can be started without setting the number of bets again, so the number of bets that are no longer required to be set in the next game (the regular bonus will not be replayed 3), In other words, it is substantially the same as paying out three medals corresponding to the bet number 3 set in the previous game in which the replay winning was generated.

  Only the small roles such as cherry, watermelon, bell, and JAC are eligible for payout of medals when winning a prize. The regular bonus, the big bonus (1), the big bonus (2), and the winning of JACIN are accompanied by the transition of the game state to the regular bonus or the big bonus, and are not eligible for paying out medals. If you win a cherry or watermelon in a game state other than the regular bonus or big bonus, the game state will be transferred to RT for the subsequent 3 games (if already RT, RT will continue until the next 3 games) To do). An RT counter for counting the number of remaining RT games is provided in the RAM 112.

  Cherry, watermelon and bell can be awarded when the bet number is 1 (regular bonus) or 3 (game state other than regular bonus), but for the bell, when the bet number is 1, That is, when the gaming state is a regular bonus, 15 medals that are more than the other 8 are paid out. Regardless of the number of bets, the number of medals to be paid out when winning a cherry is 2 per active line. If 3 wagers and the cherry stops in the upper or lower tier, the total number of medals is four. The number of medals to be paid out when winning a watermelon or JAC is 15 in both cases.

  The display mode of winning as a display result of the variable display device 2 is as described above. However, from the viewpoint of winning or losing, even if the display mode is losing, setting of winning flags such as reach eyes, chance eyes, and losing eyes is set. There are three types of display modes with different meanings depending on the situation. Here, the reach is derived as a display result of the variable display device 2 only when any of the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set. It is a certain display mode.

  The chance chance may be derived as a display result of the variable display device 2 regardless of whether the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set. It is a display mode. Losing eyes is a display mode that is not derived as a display result of the variable display device 2 when the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set. .

  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.

  The reference of the combination according to the gaming state is performed according to the winning combination table by gaming state shown in FIG. In the winning combination table according to gaming state shown in FIG. 4A, regular bonus + cherry, big bonus (1) + cherry, or big bonus (2) + cherry, or regular bonus + watermelon, big bonus (1) + watermelon Or, the big bonus (2) + watermelon means that the regular bonus, the big bonus (1), or the big bonus (2) and the cherry or watermelon are simultaneously subject to the lottery.

  When the gaming state is a regular bonus (including the case where it is provided during the big bonus), cherry, watermelon, bell, and JAC are sequentially read out as the internal lottery target roles, and the small state game with the gaming state being in the big bonus Regular Bonus + Cherry, Regular Bonus + Watermelon, Regular Bonus, Big Bonus (1) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, Cherry , Watermelon, bell, and JACIN are sequentially read out as the subject combination of the internal lottery.

  When in normal gaming or RT, regular bonus + cherry, regular bonus + watermelon, regular bonus, big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (1), big bonus (2) + Cherry, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, Bell, and Replay are sequentially read out as the subject combination of the internal lottery. Although the replay in the normal gaming state and the replay in RT are separately determined as the target for internal lottery, the replay winning flag set when winning is the same.

  In the normal gaming state or RT, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the game before the previous time, and the game is carried over without winning based on the flag. The regular bonus, the big bonus (1), and the big bonus (2) are not eligible for internal lottery.

  In the normal gaming state or RT, when the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is already set, the regular bonus + cherry or watermelon, big bonus (1 ) + Cherry or Watermelon, Big Bonus (2) + Even if Cherry or Watermelon is read out as a target for lottery, the regular bonus, Big Bonus (1), and Big Bonus (2) are actually won. You won't win, only cherries or watermelons. The same applies to the big bonus (1) and the big bonus (2) when the gaming state is a small role game in the big bonus.

  In the internal lottery, the number of judgment values determined for the target part of the internal lottery is sequentially added to the random number for the internal lottery, and when the result of the addition overflows, it is determined that the target part is won. Is done. 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. 4B 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 number is registered using a storage area for two words.

  The number of determination values of the combination to be a lottery target is registered corresponding to the number of bets (BET) set by the player in the game for each combination. This is because even if the winning combinations are the same, the winning probability in the regular bonus may be different from the winning probabilities in other gaming states. In addition, the number of determination values according to the number of bets of the combination to be a lottery object may be common regardless of the set value, and may be 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, Regular Bonus + Watermelon and Regular Bonus are subject to internal lottery in small game in normal gaming state, RT or big bonus, 3 bets in normal gaming state, RT and small role game The storage address of the number of judgment values corresponding to is registered. The value of the common flag of regular bonus + cherry and regular bonus + watermelon is 1, and the storage address of the common number of judgment values is registered regardless of the set value. The value of the common flag for the regular bonus is 0, and the storage address for the number of determination values is individually registered according to the set value.

  Big Bonus (1) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Cherry, and Big Bonus (2) + Watermelon are internal in the normal gaming state, RT or Big Bonus in a small role game The storage addresses of the number of determination values corresponding to the number of bets 3 in the normal gaming state, RT, or small role game are registered. For these roles, the value of the common flag is 1, and a storage address for the common number of determination values is registered regardless of the set value. In the small bonus game during the big bonus, the big bonus (1) and the big bonus (2) are not actually won, and here, cherry or watermelon is won.

  The big bonus (1) and the big bonus (2) are subject to internal lottery in the normal gaming state or RT, and the storage address of the judgment value number corresponding to the betting number 3 in the normal gaming state or RT is registered. Yes. 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.

  Cherry is subject to internal lottery in any gaming state, and corresponds to the storage address of the number of judgment values corresponding to the bet number 1 with the regular bonus and the bet number 3 in the normal gaming state, RT or small role game. The storage address of the number of judgment values is registered. The value of the common flag for this combination is 0, and the storage address for the number of determination values is individually registered according to the set value corresponding to the number of bets.

  The watermelon is subject to internal lottery in any gaming state, and corresponds to the storage address of the judgment value number corresponding to the bet number 1 with the regular bonus and the bet number 3 in the normal gaming state, RT or small role game. The storage address of the number of judgment values is registered. The common flag of this combination is 1, and the storage address of the common determination value number is registered regardless of the set value corresponding to each bet number. Also for the bell, the storage address of the number of determination values is registered as in the case of the watermelon.

  JACIN is subject to internal lottery only in the small role game in the big bonus, and the storage address of the number of determination values corresponding to the bet number 3 in the small role game is registered. The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value. The JAC is subject to internal lottery only with the regular bonus, and the storage address of the judgment value number corresponding to the bet number 1 with the regular bonus is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  The replay is subject to internal lottery in the normal gaming state or RT, but the storage address of the judgment value number is set to 3 bets in each gaming state as a separate lottery target in the normal gaming state and RT. Correspondingly registered. For both the replay in the normal gaming state and the replay in RT, the common flag is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  FIG. 5 is a diagram illustrating a storage area for the number of determination values acquired based on 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, in the addresses ADD + 0, ADD + 2, ADD + 16, ADD + 18, ADD + 32, and ADD + 34, the internal lottery targets are regular bonus + cherry, regular bonus + watermelon, big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (2) + Cherry, Big Bonus (2) + Watermelon and the number of bets is 3, that is, an address that is referred to regardless of the set value in the normal gaming state, RT or small role game, 10 which is the value stored in is acquired as the number of determination values.

  Addresses ADD + 4, ADD + 6, ADD + 8, ADD + 10, ADD + 12, and ADD + 14 are addresses that are referenced when the internal lottery is a regular bonus, the number of bets is 3, and the set value is 1-6. Regarding the regular bonus, the number of determination values is individually stored according to the set value, but since the same number of determination values 11 is stored, the winning probability of the regular bonus is the same at any set value. ing. Regardless of the set value, the regular bonus + cherry and regular bonus + watermelon judgment values are the same regardless of the set value, so the probability of winning the regular bonus is the same regardless of the set value. Become.

  Addresses ADD + 20, ADD + 22, ADD + 24, ADD + 26, ADD + 28, and ADD + 30 are addresses that are referenced when the internal lottery target is the big bonus (1), the bet number is 3, and the set value is 1-6. For the big bonus (1), the number of determination values is individually stored according to the set value, and different determination value numbers are stored, so that the winning probability of the big bonus (1) varies depending on the set value. It becomes. Big bonus (1) + cherry, big bonus (1) + watermelon judgment value number is common regardless of the set value, so even if you win simultaneously with cherry or watermelon, the winning probability of big bonus (1) Depends on the set value.

  The addresses ADD + 36, ADD + 38, ADD + 40, ADD + 42, ADD + 44, and ADD + 46 are addresses that are referred to when the internal lottery target role is the big bonus (2), the number of bets is 3, and the set value is 1-6. For the big bonus (2), the number of determination values is individually stored according to the set value, and different determination value numbers are stored, so that the winning probability of the big bonus (2) is different according to the set value. It becomes. Big bonus (2) + cherry, big bonus (2) + watermelon judgment value number is common regardless of the set value, so even if you win simultaneously with cherry or watermelon, the winning probability of big bonus (2) Depends on the set value.

  Addresses ADD + 48, ADD + 50, ADD + 52, ADD + 54, ADD + 56, and ADD + 58 are each when the number of bets is 3, that is, when the set value is 1 to 6 in the normal game state or the small role game and the target lot of the internal lottery is cherry The address to be referenced. Addresses ADD + 60, ADD + 62, ADD + 64, ADD + 66, ADD + 68, and ADD + 70 are addresses that are referenced when the bet number is 1, that is, when the target character of the internal lottery is a cherry and the set value is 1 to 6 in the regular bonus It is.

  With respect to cherries, the number of determination values is stored individually according to the gaming state and the set value, and different determination value numbers are stored, so that the winning probabilities differ according to the gaming state and the set value. Regular bonus + Cherry, Big bonus (1) + Cherry, Big bonus (2) + Cherry The number of judgment values is the same regardless of the set value, so regular bonus, big bonus (1), or big bonus (2) Even when winning at the same time is included, the winning probability of cherry varies depending on the set value.

  The address ADD + 76 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state, RT or small role game, when the target combination of the internal lottery is a watermelon. The address ADD + 78 is an address that is referred to regardless of the set value when the bet number is 1, that is, in the regular bonus, when the target character of the internal lottery is a watermelon. The number of determination values for watermelon is registered according to the number of bets, but since the same value is registered, the winning probability of watermelon is the same in any gaming state.

  The address ADD + 76 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state, RT, or the small lottery game, when the internal lottery target role is a bell. The address ADD + 78 is an address that is referred to regardless of the set value when the number of bets is 1, that is, in the regular bonus, when the target character of the internal lottery is a bell. The number of judgment values for the bell is registered according to the number of bets, but since different values are registered, there is a case where the game state is a regular bonus and a small value in the normal game state, RT or big bonus. The probability of winning the bell will differ depending on the role game.

  In addition, addresses ADD + 80, ADD + 82, ADD + 84, and ADD + 86 respectively have an internal lottery subject of JACIN with 3 bets, JAC with 1 bet, normal replay with 3 bets, RT with replay with 3 bets Is an address referred to regardless of the set value, and 27, 4431, 2245, and 12552 are acquired as the number of determination values, respectively, regardless of the set value.

  FIGS. 6A and 6B are diagrams showing an example of the relationship between the value of the random numbers for internal lottery and the number of determination values of each combination and the winning combination. FIGS. 6A and 6B show examples in which the set value is 6 when both are in the normal gaming state. FIG. 6A shows an example in which none of the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set. FIG. 6B shows an example in which any of the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set.

  For example, as shown in FIG. 6 (a), when the bonus winning flag is not set in the normal gaming state, the roles that are subject to the internal lottery are regular bonus + cherry, regular bonus + watermelon, regular Bonus, Big Bonus (1) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (1), Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, Bell, normal replay. In the set value 6, the number of determination values is 10, 10, 11, 10, 10, 10, 10, 10, 10, 243, 38, 3370, 2245.

  First, the regular bonus + cherry that is the target of the internal lottery will be awarded when 16374-16383, which will result in an overflow of the addition result by adding 10 judgment values, is acquired as a random number for internal lottery. Become. Next, the regular bonus + watermelon that will be the subject of the internal lottery will add 20 that is the sum of the regular bonus + cherry judgment value number 10 and the regular bonus + watermelon judgment value number 10. Are obtained when 16364 to 16373 are acquired as random numbers for internal lottery. Next, the regular bonus that will be the target of the internal lottery is 31 which is the sum of the regular bonus + cherry judgment value number 10, the regular bonus + watermelon judgment value number 10, and the regular bonus judgment value number 11. The winning result is obtained when 16353 to 16363, which will cause the addition result to overflow, are acquired as random numbers for internal lottery.

  Similarly, when Big Bonus (1) + Cherry is acquired as a random number for internal lottery from 16343 to 16352, Big Bonus (1) + Cherry is acquired as a random number for internal lottery from 16333 to 16342 Sometimes, the big bonus (1) is determined to be winning when 16323 to 16332 are acquired as random numbers for internal lottery. Big Bonus (2) + Cherry is obtained when 16313-16322 is acquired as a random number for internal lottery, Big Bonus (2) + Watermelon is acquired when 16303-1631 is acquired as a random number for internal lottery, Big bonus (2) is determined as winning when 16293-16302 are acquired as random numbers for internal lottery.

  Further, when 16060-16292 is acquired as a random number for internal lottery, Cherry is acquired as a random number for internal lottery when 16012-16160 is acquired as a random number for internal lottery. The replay is determined to be a win when 10397 to 12461 are acquired as random numbers for internal lottery. When 0-10396 not corresponding to the above is acquired as a random number for internal lottery, all combinations are lost.

  The approximate winning probabilities calculated based on the number of judgment values are as follows: regular bonus + cherry, regular bonus + watermelon, regular bonus, big bonus (1) + cherry, big bonus (1) + watermelon, big For each of Bonus (1), Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, Bell, and Replay, 1 / 1638.4, 1 / 11638.4, 1 / 11489.5, 1 / 11638.4, 1 / 11638.4, 1 / 11638.4, 1 / 11638.4, 1 / 11638.4, 1 / 11638.4, 1 / 67.4, 1 / 431.2, 1 / 4.7, and 1 / 7.3.

  Further, as shown in FIG. 6B, when the bonus winning flag is set in the normal gaming state, the winning role for the internal lottery is cherry (regular bonus + cherry, big bonus (1 ) + Cherry, big bonus (2) + cherry is read out as an internal lottery target, and only the cherry lottery is substantially performed (the same applies to the explanation of FIG. 6B), watermelon (Regular Bonus + Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon is read out as a target for internal lottery, and the case where only watermelon lottery is actually performed is included. The same applies to the explanation of (b)), bell, and normal replay are the subject of internal lottery.

  Cherry, watermelon, bell, and replay have 30 + 243, 30 + 38, 3370, and 2245 judgment values, respectively, so that when a random number for internal lottery with values as shown in FIG. It is determined. When 0-10427 is acquired as a random number for internal lottery, all the combinations are lost. In addition, the approximate winning probabilities of each combination are 1 / 60.0, 1 / 240.9, 1 / 4.7, and 1 / 7.3.

  For a combination determined to be won in the internal lottery, a winning flag for the combination is set in the RAM 112. The regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag set in the normal gaming state or RT is carried over after the next game if no winning is generated based on them. It will be a thing. In other cases, the winning flags for each combination are deleted only for the game. The watermelon winning flag and the cherry winning flag set by winning at the same time as the regular bonus, the big bonus (1) or the big bonus (2) are also deleted as long as the game is concerned.

  Even if the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over in the normal gaming state or RT, the small role and replay lottery is performed (regular bonus + Cherry or watermelon, Big Bonus (1) + Cherry or Watermelon, Big Bonus (2) + Cherry or Watermelon is read as an internal lottery target, and only a lottery of cherry or watermelon is actually performed If you win a small role or replay, the regular bonus winning flag, big bonus (1) winning flag, big bonus (2) winning flag, and the winning flag for small role or replay will be set redundantly. .

  Next, acquisition of random numbers for internal lottery will be described in detail. 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 extracted from the random number generation circuit 115 or processed from 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.

  First, extraction of random numbers from the random number generation circuit 115 will be described. 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. A carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. 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 is configured by a latch circuit, and latches the 16-bit data signal output at that time from the random number generation circuit 115 based on a sampling command from the CPU 111 and outputs the latched 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.

  Next, processing of random numbers extracted from the random number generation circuit 115 by software will be described. 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 determines the determination value (actual value) of each combination registered in the winning determination table. Are sequentially compared with the upper limit judgment value only). 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 during the period 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.

  When the winning flag is set according to the result of the internal lottery, the rotation of the reels 3L, 3C, 3R is stopped according to the setting state of the winning flag (including those carried over from the previous game) A reel control table for selecting a stop symbol is selected. FIG. 8 is a diagram illustrating an example of a reel control table selected for each setting state of the winning flag and the control contents.

  In FIG. 8, the control content of the reel control table indicates that the priority of derivation is higher in the display mode shown on the left. For example, “regular bonus> reach eye> chance eye” in the 0th table selected when only the regular bonus winning flag is set is 190 milliseconds from the operation of the stop buttons 12L, 12C, 12R. If the display mode of the regular bonus can be derived in the range of the maximum stop delay time (that is, the range of pulling in 4 frames), it indicates that the control content for deriving the display mode of the regular bonus is written in the table.

  If the reach can be derived even if the display mode of the regular bonus cannot be derived within the range of the maximum stop delay time of 190 milliseconds, it indicates that the control content for deriving the reach is written in the table. If the reach is not derived in the range of the maximum stop delay time of 190 milliseconds, it indicates that the control content for deriving the chance eye in the range of the maximum stop delay time of 190 milliseconds is written in the table. Further, when the 0th table is selected, a display mode not described here, that is, a display mode or a dismissal that is a winning combination of another combination is not derived.

  Further, for example, in the seventh reel control table selected when the regular bonus winning flag and the watermelon winning flag are set to overlap, only “watermelon” is described as the content of the reel control. This indicates that the control content for deriving the display mode of “watermelon” is always written in the range of the maximum stop delay time of 190 milliseconds from the operation of the stop buttons 12L, 12C, and 12R. This is based on the fact that “watermelon” symbols are arranged at intervals of 5 frames at the maximum in the reels 3L, 3C, 3R.

  Further, as can be seen from FIG. 8, even when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set, the watermelon winning flag, the bell winning flag or the replay winning is set. If the flag is also set redundantly, the display mode of watermelon, bell or replay is always derived. Even when the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set, if the cherry winning flag is also set, the cherry display mode Is preferentially derived. In other words, the priority of derivation is higher for non-special roles such as small roles and replays.

  The CPU 121 of the effect control board 102 performs an effect by original control based on various commands sent from the CPU 111 of the game control board 101. As an effect controlled by the CPU 121 of the effect control unit 102, the player is shown that a bonus is won in RT that continues in three games after winning the small part of “Cherry” or “Watermelon” There is a bonus production that continues until the end of RT.

  When the start lever 11 is operated when the gaming state is at RT, the bonus roll effect is selected from a plurality of types of effect patterns, and an image of the selected effect pattern is displayed on the liquid crystal display. 4 is displayed. The selection ratio of the production pattern is when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set, and the regular bonus winning flag or big bonus (1) winning flag. And Big Bonus (2) It differs depending on when no winning flag is set. That is, the degree of expectation for the setting of the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag differs depending on the effect pattern.

  The CPU 121 of the effect control board 102 must be able to recognize the setting status of the winning flag in the RAM 112, whether or not the gaming state is in RT, and the number of remaining games in the RT in order to perform such bonus incentive effects. For this reason, when the CPU 111 of the game control board 101 performs an internal lottery by operating the start lever 11, it generates a winning status notification command indicating the setting status of the winning flag in the RAM 112 and transmits it to the effect control board 102. In addition, at the end of each game, a state command indicating a gaming state applied to the next game (for RT, up to the remaining number of games) is generated and transmitted to the effect control board 102.

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. 9 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 the reset signal is input from the reset circuit 118 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). In this embodiment, whether or not the RAM 112 is normal based on the RAM parity is determined only in the startup process.

  If the RAM parities do not match in step S106, the data stored in the RAM 112 is not normal, and the routine proceeds to the RAM abnormality error processing 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, all the data stored in the RAM 112 is initialized except for the area in use in the stack area 112-6 (other than the setting value work 112-4). Is rewritten to 0 and the set value work 112-4 is rewritten to 0) (step S109), the prohibition of interruption is canceled (step S110), and the process proceeds to the setting change process shown in FIG. 10 (step S111). Then, after the setting change process is completed, the game can be progressed and the process proceeds to the game control process.

  FIG. 10 is a flowchart showing in detail the setting change process executed by the CPU 111 in step S111. 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 (setting change) stored in the setting value work 112-4 is set. Before shifting to the processing, the value of the set value work 112-4 has been rewritten to 1, so it is 1 here) (step S202).

  Thereafter, the operation waits for detection of the operation of the setting switch 91 and the start switch 41 (steps S203 and S204). When the operation of the setting switch 91 is detected in step S203, 1 is added to the setting value read in step S102 (step S205), and whether or not the setting value after the addition is 7, that is, whether the normal range has been exceeded. No, it means halfway (step S206). If the set value after addition is not 7, the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204. If the set value after addition is 7, the set value is corrected to 1 (step S207), and the process returns to the state of waiting for detection of the operation of the setting switch 91 and the start switch 41 in steps S203 and S204.

  When the operation of the start switch 41 is detected in step S204, 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). Then, when returning to the flowchart of FIG. 9, the game can be progressed and the game control process is started.

  FIG. 11 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 game number display unit 51 is controlled to display the RAM abnormality error code on the game number display unit 21 (step S301), and then the process proceeds to a loop process in which no process is performed.

  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 game number 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. In other words, since no new RAM parity is calculated and stored in the power interruption process, the RAM parity is always set except when the setting key switch 92 is activated even when the control unit 110 is activated. Since they do not match, the control unit 110 cannot be activated to start (resume) the game.

  Once the RAM abnormal error state is entered, the setting key switch 92 is turned on, the setting key switch 92 is turned on, setting change processing is performed, and a new set value is selected and set by operating the setting switch 91 until the game is played. It becomes impossible to progress. That is, in the state that has shifted to the RAM abnormal error mode state, the state in which the game cannot be progressed is canceled and the game is started (resumed) on condition that a setting value is newly selected and set by operating the setting switch 91. ). In the error state other than the RAM abnormal error, there is no problem of the RAM parity mismatch, so that the state where the game cannot be progressed is canceled only by the operation of the first reset switch 48 or the second reset switch 93, and the game is resumed. Can be made.

  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. 12 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, an initial process including a process of clearing a predetermined area of the RAM 112 is first 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). In the BET processing, when the operation of the start lever 11 becomes valid as shown below, that is, when the setting of the bet number is confirmed, a BET command is generated and transmitted to the effect control board 102.

  Here, when the gaming state is a regular bonus (including the case where the bonus is provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is operated effectively. It becomes. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, 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 flag (the replay flag is erased at this stage) and remains as it is. The start lever 11 becomes effective.

  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 this lottery process, a winning flag is set in the RAM 112 based on each lottery result, and a reel control table is selected. In addition, a winning status notification command indicating the setting status of the winning flag 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 fluctuation start process is performed (step S404). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed 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. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. Here, when a predetermined time has not elapsed since the start of rotation in the previous game, the rotation is awaited for rotation, and the weight display unit 31 is notified by lighting the weight lamp 61. Also, the timing of one game timer for the next game is started.

  Thereafter, reel fluctuation stop processing is performed (step S405). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R are made effective, and each is operated by a player to stop driving the reel motors 3ML, 3MC, 3MR with reference to a reel control table preselected according to the setting status of the winning flag, The rotation of 3C and 3R is stopped.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the active 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 S406). 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. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S407). 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. Various processes not related to winning are also performed, and a state command indicating a gaming state to be applied in the next game is transmitted 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 lottery process in step S403 will be described in detail. FIG. 13 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S403. In the lottery process, a random number acquisition process is performed, and a random number generated by the random number generation circuit 115 is output by the sampling circuit 116 by outputting a sampling command, and the extracted random number is processed into a random number for internal lottery. It is stored in a random number storage area for internal lottery (step S501). Details of the random number acquisition process will be described later.

  Next, the set value stored in the set value work 112-4 of the RAM 112 is read (step S502), and 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 S503). 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. 11 is performed.

  If the read set value is in the range of 1 to 6, the lottery target combination registered in the winning combination table according to gaming state in FIG. 4A is read in order corresponding to the current gaming state ( Step S504). Next, the number of BETs set in the current game is read out, and the setting state of the common flag in the combination table in FIG. 4B is acquired corresponding to the number of BETs read out for the lottery target combination (step) S505). As a result, it is determined whether the common flag is set (step S506).

  If the common flag is set, the number of determination values stored in the address registered in the role-specific table of FIG. 4B corresponding to the number of BETs for the lottery target role is acquired (step S507). ). Then, the process proceeds to step S509. 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 role-specific table corresponding to the BET number and the read setting value for the lottery target role. The number of determination values that are present is acquired (step S508). Then, the process proceeds to step S509.

  In step S509, the number of determination values acquired in step S507 or S508 is added to the internal lottery random number value stored in the determination area of the RAM 112, and the addition result 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 S510).

  If no overflow has occurred, it is determined whether or not there is a combination that has not yet been processed among the lottery targets in the gaming state (step S511). If there is something that has not yet been processed, the process returns to the processing of step S504, and the processing is continued with the next lottery target registered in the winning combination table according to gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S523.

  If an overflow occurs, it is determined whether or not the winning combination is regular bonus + cherry or regular bonus + watermelon (step S512). If the lottery target is neither regular bonus + cherry nor regular bonus + watermelon, the process directly proceeds to step S515. In the case of regular bonus + cherry or regular bonus + watermelon, the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is already set in the RAM 112 in the previous game, and the winning Based on the flag, it is determined whether or not it has been carried over without winning (step S513).

  If neither the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the regular bonus winning flag and the cherry winning flag or the watermelon winning flag are set in the RAM 112 (step S514). ). Then, the process proceeds to step S523 as it is. If the winning combination is regular bonus + cherry or regular bonus + watermelon, and the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is already set, step S519 Proceed to processing.

  In step S515, it is determined whether or not the winning combination is one of big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (2) + cherry, big bonus (2) + watermelon. . If the lottery target is neither big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (2) + cherry, big bonus (2) + watermelon, the process proceeds to step S520. In the case of big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (2) + cherry, big bonus (2) + watermelon, the big bonus medium flag is set in RAM 112. Whether or not the current gaming state is in the big bonus is determined based on whether or not there is (step S516).

  If the current gaming state is not a big bonus, a regular bonus winning flag, a big bonus (1) winning flag, or a big bonus (2) winning flag is already set in the RAM 112 in the game before the previous game, and based on the winning flag. Then, it is determined whether or not it is carried over without winning a prize (step S517). If neither the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the RAM 112 stores the big bonus (1) winning flag or the big bonus (2) winning flag and cherry. A winning flag or a watermelon winning flag is set (step S518). Then, the process proceeds to step S523 as it is.

  The lottery is one of Big Bonus (1) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, and the current gaming state is Big Bonus Or if the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag has already been set, the process proceeds to step S519. In step S519, a cherry winning flag or a watermelon winning flag is set in the RAM 112. Then, the process proceeds to step S523.

  In step S520, it is determined whether the lottery target is a regular bonus, a big bonus (1), or a big bonus (2). If the lottery target is not any of the regular bonus, the big bonus (1), and the big bonus (2), the process proceeds to step S522. If the winning combination is a regular bonus, a big bonus (1) or a big bonus (2), the regular bonus winning flag, the big bonus (1) winning flag, or the big It is determined whether or not the bonus (2) winning flag has already been set and is carried over without winning based on the winning flag (step S521). If the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set, the process proceeds to step S523 as it is.

  If none of the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is set, the process proceeds to step S522. In step S522, a winning flag (in this case, only one of them) for the winning combination is set in the RAM 112. Then, the process proceeds to step S523.

  In step S523, a reel control table corresponding to the setting status of the winning flag in the RAM 112 is selected. Further, it is determined whether or not the value of the RT counter in the RAM 112 is 0, that is, whether or not the gaming state is other than RT (step S524). If the value of the RT counter is 0, the process proceeds to step S526 as it is. If the value of the RT counter is not 0, the RT counter value is subtracted by 1 (step S525), and the process proceeds to step S526. Proceed to processing. In step S526, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is generated and transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the random number acquisition process in step S501 will be described in detail. FIG. 14 is a flowchart showing in detail the random number acquisition process executed by the CPU 111 in step S501. In the random number acquisition process, first, an interrupt to the CPU 111 is prohibited (step S601). 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 S602).

  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 (step S603). Next, the value of the random number stored in the general-purpose register 111GR is ANDed with 8080h (step S604). 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 S605). Then, after permitting the interrupt prohibited in step S601 (step S606), the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S406 will be described in detail. FIG. 15 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S406. First, it is determined whether a regular bonus display mode (BAR-BAR-BAR) or a JACIN display mode (watermelon-JAC-JAC) is derived on any active line (step S701).

  If the display mode of the regular bonus or the display mode of JACIN is derived, the gaming state becomes the regular bonus from the next game. Therefore, the number of games in the regular bonus in the RAM 112 and the counter value for counting winnings are initialized, and a regular bonus flag is set in the RAM 112. If the regular bonus winning flag is set in the RAM 112, it is deleted (step S702). In any case, the JACIN winning flag is deleted in step S810, which will be described later, so it is not necessary to delete the JACIN winning flag here even if JACIN wins. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If neither the regular bonus display mode nor the JACIN display mode is derived, the big bonus (1) display mode (red 7-red 7-red 7) or the big bonus (2) is displayed on any active line. It is determined whether an aspect (white 7-white 7-white 7) has been derived (step S703).

  If the display mode of the big bonus (1) or the big bonus (2) is derived, the gaming state becomes the big bonus from the next game. Therefore, a counter value for counting the number of payout medals in the big bonus in the RAM 112 is initialized, and a big bonus medium flag is set in the RAM 112. Further, the big bonus (1) winning flag or the big bonus (2) winning flag set in the RAM 112 is erased (step S704). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  When neither the display mode of the big bonus (1) nor the display mode of the big bonus (2) is derived, it is determined whether or not the display mode of cherry (cherry-ANY-ANY) is derived on any active line. Determination is made (step S705). If the cherry display mode is derived, 2 or 4 is set as the planned medal payout number according to the number of active lines from which the cherry display mode is derived (step S706).

  Also, it is determined whether the regular bonus flag and / or the big bonus flag is set in the RAM 112 (step S707). If the regular bonus medium flag and / or the big bonus medium flag are set, the winning determination process is terminated and the process returns to the flowchart of FIG. If neither the regular bonus medium flag nor the big bonus medium flag is set, 3 is set in the RT counter of the RAM 112 because it is a normal game state or a cherry winning in RT (step S708). As a result, the next and subsequent three games RT are continued. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the display mode of cherry is not derived, it is determined whether or not the display mode of watermelon (watermelon-watermelon-watermelon) is derived on any effective line (step S709). If the display mode of the watermelon has been derived, 15 is set as the planned payout number of medals (step S710).

  Further, it is determined whether the regular bonus flag and / or the big bonus flag is set in the RAM 112 (step S711). If the regular bonus medium flag and / or the big bonus medium flag are set, the winning determination process is terminated and the process returns to the flowchart of FIG. If neither the regular bonus medium flag nor the big bonus medium flag is set, 3 is set in the RT counter of the RAM 112 because it is a normal gaming state or a watermelon winning in RT (step S712). As a result, the next and subsequent three games RT are continued. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the display mode of the watermelon has not been derived, it is determined whether or not the display mode of the bell (bell-bell-bell) has been derived on any effective line (step S713). If the bell display mode is derived, 15 (regular bonus) or 8 (normal game state, RT or small role game) is set as the expected payout number of medals (step S714). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the bell display mode is not derived, it is determined whether or not the JAC display mode (Bell-JAC-JAC) is derived on any valid line (step S715). If the display mode of JAC is derived, 15 is set as the planned payout number of medals according to the bet number set in step S402 (step S716). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the JAC display mode has not been derived, it is determined whether or not the replay display mode (JAC-JAC-JAC) has been derived on any active line (step S717). If the replay display mode is derived, a replay flag is set in the RAM 112 (step S718). This replay flag is deleted when the bet number is automatically set in the next game. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG. When the display mode of replay is not derived, the winning determination process is terminated as it is, and the process returns to the flowchart of FIG.

  Next, the payout process in step S407 described above will be described in detail. FIG. 16 is a flowchart showing in detail the payout process executed by the CPU 111 in step S407. In the payout process, until the planned payout number set in the RAM 112 becomes 0, the hopper 80 is controlled while subtracting the payout number one by one and the medals are discharged one by one, so that it corresponds to the winning combination Pay the number of medals to the player. However, if the number of credits has not reached 50, the number of credits is incremented by 1 instead of discharging medals one by one (step S801).

  Next, 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 (step S802). If the current gaming state is not a big bonus, the process proceeds to step S806. If the current gaming state is a big bonus, the number of payout medals in the big bonus is counted using the counter of the RAM 112 (step S803). The number of payout medals counted here exceeds 465, and it is determined whether or not the big end condition is satisfied (step S804).

  If the number of payout medals does not exceed 465, the process proceeds to step S806. If the number of payout medals exceeds 465 and the big bonus ending condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus flag is set, it is also deleted (step S805). Then, the process proceeds to step S810.

  In step S806, 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 S810. If the current gaming state is a regular bonus, the number of games and winnings in the regular bonus are counted using the counter of the RAM 112 (step S807).

  As a result of the count, it is determined whether the number of games has reached 12 or the number of winnings has reached 8, which is a regular bonus termination condition (step S808). If the number of games is less than 12 and the number of winnings is less than 8, the process proceeds to step S810 as it is. If the number of games has reached 12 or the number of winnings has reached 8, the regular bonus flag in the RAM 112 is erased (step S809). Then, the process proceeds to step S810.

  In step S810, if the small role winning flag, the JAC winning flag, the replay winning flag, and the JACIN winning flag are set in the RAM 112, these are deleted. The regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are not deleted from the RAM 112 unless they have won the corresponding role in the game, and are carried over to the next game.

  Further, based on whether or not the big bonus medium flag and / or the regular bonus medium flag are set in the RAM 112, and the RT counter value of the RAM 112, the game state applied in the next game and the number of remaining RT games are indicated. A game state command is generated and transmitted to the effect control board 102 (step S811). Then, the payout process is ended, and the process returns to the flowchart of FIG.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, RT, regular bonus, and big bonus, and issues a command according to the progress of the game. It is transmitted to the production 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. In the following, processing executed by the CPU 121 of the effect control board 102 for performing various effects (particularly, bonus bonus effects when the gaming state is at RT) will be described.

  FIG. 17 is a flowchart showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S901). When any command is received from the game control board 101, the type of the received command is determined (step S902).

  If the received command type is the state command transmitted in step S811, the state command stored in the previous game is overwritten and stored in a predetermined area of the RAM 122 (step S903). Then, the process returns to step S901.

  If the received command type is the winning status notification command transmitted in step S526, it is determined whether or not the status command stored in the RAM 122 indicates that the gaming status in the game is RT. (Step S904). If the game state in the game is RT, the effect pattern is selected according to the number of remaining RT games indicated by the status command, the regular bonus indicated by the received winning status notification command, etc., and the bonus in the selected pattern is selected. The turning effect is performed on the liquid crystal display 4 (step S905). Then, the process returns to step S901.

  If the gaming state in the game is not RT, the gaming state indicated by the state command stored in the RAM 122 (usually, a regular bonus or a small role game in the big bonus) and a winning flag indicated by the received winning situation notification command A predetermined effect is performed according to the setting status (step S906). Since the effects here are not related to the present invention, a detailed description thereof will be omitted. Then, the process returns to step S901.

  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 S907). Thereafter, the process returns to step 901.

  As described above, in the slot machine 1 according to this embodiment, the number of determination values in the normal gaming state includes both the regular bonus, the big bonus (1), or the big bonus (2) and the cherry or the watermelon. Are registered for the 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 big bonus (1) or big bonus (2) and cherry or watermelon will be won.

  Here, based on the display result of the variable display device 2 based on the cherry winning flag or the watermelon winning flag set based on the winning of the cherry or watermelon that is one of the lottery targets, the small value of “cherry” or “watermelon” Even if the winning combination is won, there is still a possibility that any of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag is set. For this reason, even when winning the small role of “Cherry” or “Watermelon”, the player can expect to win the regular bonus, the big bonus (1), or the big bonus (2). Can improve the interest of

  Regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry, regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon However, the number of determination values for cherry only is different from the number of determination values for watermelon only. Therefore, the probability of winning the regular bonus, big bonus (1) or big bonus (2) when winning the “cherry” small role, and the regular bonus when winning the “watermelon” small role, The probability of winning the big bonus (1) or the big bonus (2) will be different. Thereby, it is possible to give the player a sense of expectation that is different between when winning the “cherry” and when winning the “watermelon”, thereby improving the fun of the game.

  Also, when winning a small role of “Cherry” or “Watermelon”, the gaming state is controlled to RT only for three games from there. When the gaming state is controlled by RT, the probability of winning a replay becomes very high, and considering the probability of winning a “watermelon” or “bell” that is not missed, replay, watermelon or The winning flag for the bell is set.

  When the replay, watermelon or bell win flag is set, regardless of whether the regular bonus, big bonus (1) or big bonus (2) win flag is set, the replay, watermelon or bell will always be The reel control table to be won is selected. Even when the missed cherry winning flag is set, even when the regular bonus, big bonus (1), or big bonus (2) winning flag is set, the winning of the cherry wins. The reel control table is selected.

  In this way, when the winning of “Cherry” or “Watermelon”, which is likely to be won for regular bonus, big bonus (1) or big bonus (2), is often controlled by the control to RT. Will not know whether the player has actually won the regular bonus, big bonus (1), or big bonus (2) over the next three games. , You can improve the fun of the game. Moreover, when the gaming state is at RT, a bonus squealing effect is also performed, so that the player's sense of expectation for winning the regular bonus, the big bonus (1) or the big bonus (2) by this bonus squeezing effect. Can increase the interest of the game.

  Furthermore, the bonus squeak effect is not simply performed based on whether or not the gaming state is controlled by RT, and the regular bonus, the big bonus (1) or the big bonus (2) winning flag is set. The production pattern is selected at a different rate depending on whether or not it is performed. For this reason, it is possible to give the player a sense of expectation having a different degree according to the difference in the production pattern in the bonus production effect, so that the interest of the game can be further improved.

  In addition, if it is determined that the regular bonus, big bonus (1), or big bonus (2) and both the cherry or watermelon are selected, the regular bonus is won from the previous game. If none of the flag, big bonus (1) winning flag, and big bonus (2) winning flag are carried forward, the regular bonus, big bonus (1), or big bonus (2 ) And cherry or watermelon, and if any of the regular bonus winning flag, big bonus (1) winning flag, big bonus (2) winning flag is carried over from the previous game, All you need is a watermelon. For this reason, in the internal lottery in the normal gaming state, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is read out from the previous game. There is no need to change the number of judgment values.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. In the role-specific table, for the cherry, watermelon, and bell that are determined as winning combinations in any gaming state, the storage address of the determination value number is registered for each bet number, and the determination value number according to the bet number Will be acquired.

  Here, the number of bets in the regular bonus is fixed at 1, but the number of bets in the gaming state other than the regular bonus is fixed at 3. As a result, the cherry, watermelon, and bell internal lottery can be performed with the winning probability corresponding to the gaming state only by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified.

  Moreover, the betting number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the betting number is 3, so that the player's expectation in the regular bonus is further increased and the interest of the game is improved. Can do. Furthermore, since the number of bets paid out in the 1st bet corresponding to the regular bonus is more than the number of bets paid out at the time of winning the bell, the player's expectation in the regular bonus is further enhanced. Interest can be improved.

  In addition, the storage address of the judgment value number of each combination registered in the combination table may differ depending on the set value, but the winning probability is the same regardless of the set value. For the winning combination, 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.

  By the way, in the slot machine 1 according to this embodiment, when the number of determination values corresponding to the combination to be selected for the lottery is sequentially added to the random number for internal lottery according to the gaming state, and the result of the addition overflows It is determined that the winning combination has been won. When the internal lottery is performed in this way, the processing efficiency is high, but the determination value as to whether or not each winning combination is won is determined and determined for each winning combination.

  However, 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. Thereby, it is possible to prevent the player from hitting as much as possible by losing the periodicity of the random numbers for internal lottery 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. For this reason, the effect of preventing aiming by the player is further enhanced.

  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.

  Further, in the slot machine 1 according to this embodiment, when an abnormality occurs in the data stored in the RAM 112, the RAM is controlled to an abnormal error state of the RAM, the progress of the game is disabled, and the setting change mode is set. If the setting value is not newly selected / set based on the setting change operation, the game disabled state is not released. That is, even if an abnormality occurs in the data stored in the RAM 112, the setting value selected and set based on the setting change operation (in general, the setting value) is not set automatically by the slot machine 1. Since the change operation is performed by an employee of the game shop, it is ensured that the game is played based on the setting value selected by the game shop), so that the game can be fair.

  In addition, when determining whether or not to win the winning combination in the internal lottery, the set value stored in the set value work 112-4 must be an appropriate value (a value in the range of 1 to 6). For example, instead of deciding whether or not to win based on a probability based on a default setting value (for example, setting 1), in this case as well, the game is controlled to a RAM abnormal error state and the progress of the game is disabled. If the setting change mode is entered and a new setting value is not selected or set based on the setting change operation, the state where the progress of the game is disabled is not released. In other words, even when it is not possible to properly determine whether or not to win the winning combination in the internal lottery, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, the fairness of the game can be achieved.

  Further, the data stored in the RAM 112 is abnormal in most cases when the control cannot be continued due to a malfunction in the control such as a power failure or the control unit 110 running away. Since it is determined whether or not the data is normal only when the control unit 110 is activated after recovering from these states, the determination whether or not the data stored in the RAM 112 is normal is abnormal. Can only be done in situations where there is a high probability that 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. is 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, when an abnormality occurs in the data of the RAM 112 and the progress of the game is disabled, a setting change mode in which a setting value changing operation that becomes a condition for releasing the disabled state of the game is enabled The data stored in the RAM 112 is initialized in accordance with the transition to (setting change processing). For this reason, the initialization of data associated with the occurrence of an abnormality in the data in the RAM 112 and the initialization of data associated with selection / setting of the set value can be performed at one time, so that useless processing can be omitted. .

  Further, when the control unit 110 is activated, it is determined whether or not the setting key switch 92 is ON before determining whether or not the data in the RAM 112 is normal. At that time, the setting key switch 92 is If it is determined that the data is in the ON state, the process proceeds to the setting change mode without determining whether the data in the RAM 112 is normal. In this way, a new set value is selected and set without determining whether or not the data in the RAM 112 is normal, so that useless processing can be omitted.

  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, in the winning combination table according to the game state, the winning combinations are regular bonus + cherry, regular bonus + watermelon, regular bonus, big bonus (1) + cherry, big bonus (1) + watermelon, Big Bonus (1), Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, Big Bonus (2), Cherry, Watermelon, ..., replay order, for example, regular bonus + cherry Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Cherry, Regular Bonus + Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon, Watermelon, ..., Replay, Regular Bonus, Big Ascending in order of bonus (1) and big bonus (2) It may be intended to.

  Thus, regardless of whether the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set, the range of determination values to be won at least for cherry and watermelon is the same. Therefore, for the bells and replays that are subsequently subject to internal lottery, the range of determination values to be won is the same regardless of whether the bonus winning flag is already set in the normal gaming state or RT. be able to.

  In the above embodiment, the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag accompanying the transition to the regular bonus or the big bonus are carried over after the next game if no winning occurs. However, the JACIN winning flag that accompanies the transition to the regular bonus is deleted only for the game regardless of whether or not a prize has been won. Of course, the JACIN winning flag can also be carried over from the next game until a winning occurs. Even when the gaming state is a small role game with a big bonus, a regular bonus lottery may not be performed separately from JACIN.

  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 determination values of a combination such as regular bonus, big bonus (1), big bonus (2), big bonus (3) is set to exceed 255 in any gaming situation. It is impossible. 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, the number of determination values acquired according to the set value or the like is sequentially added to the random number value for internal lottery. That is, in the slot machine of the present invention, when the range specifying data is determination value data indicating the number of determination values,
The range determining means sequentially adds the range specifying data stored in the range specifying data storage means corresponding to the allowable stage set by the allowable stage setting means to the determination numerical data input to the determination area. It is possible to determine whether or not the addition result of the adding means has exceeded the predetermined range (overflow) (step S510).

  Thus, after the determination value data is taken out from the range specifying data storage means, the determination value numerical data is added to this, and the determination numerical data is determined by whether or not the result of the addition exceeds a predetermined range. It can be determined whether or not it is included in the range of determination values specified by. In other words, since the process of registering the range of the determination value specified by the range specifying data anew in the data storage means is not required, the processing efficiency is high.

  However, the number of determination values acquired in accordance with the set value or the like may be sequentially subtracted from the acquired internal lottery random value, and the subtraction result 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, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not In this case, in the slot machine of the present invention,

  The range determination means uses the determination value data stored in the determination value data storage means corresponding to the type of allowable level set by the allowable level setting means, instead of the addition means, Subtracting means for subtracting from the numerical value data for determination input to the determination area sequentially every time, and the determination means determines whether or not the subtraction result of the subtraction means has become smaller than the predetermined range. can do.

  In the above embodiment, the internal lottery is performed by sequentially adding the number of determination values of the lottery target according to the game situation to the acquired random number for internal lottery, and when the addition result overflows The role was determined to be a winner. On the other hand, according to the number of determination values of each combination according to the game situation, using the winning determination table that determines the determination value for determining each combination as winning, the acquired internal lottery random value value It is good also as what performs an internal lottery by comparing with the determination value of each combination.

  In the above embodiment, the number of determination values sequentially added to the random numbers for internal lottery wins both regular bonus, big bonus (1) or big bonus (2) and cherry or watermelon. was there. That is, the special bonus lottery of the regular bonus, the big bonus (1) or the big bonus (2) and the non-special lottery of the small role cherry and watermelon are simultaneously performed with the same number of determination values. On the other hand, the lottery for special roles and the lottery for non-special roles may be performed separately.

  The following is an example of internal lottery using separate winning determination tables for special roles and non-special roles, depending on the random number for internal lottery. An example of an internal lottery that may be won simultaneously will be described. The slot machine that performs such an internal lottery can also be configured to achieve the same purpose as the slot machine 1 in the above embodiment.

Such a slot machine (hereinafter referred to as a slot machine of another invention)
By setting a predetermined number of bets for one game, the game can be started, and the display result is displayed on a variable display device (variable display device 2) that variably displays a plurality of types of identification information each of which can be identified. In a slot machine in which one game is completed by being derived and winning can be generated according to the display result derived to the variable display device,
Numerical data input means (step S501) for inputting numerical data to be updated within a predetermined range into a determination area predetermined as determination numerical data for each game at a predetermined timing;
Range determination for determining which of a plurality of predetermined range of determination values is included in the determination numerical data input to the determination area before the display result of the variable display device is derived And a special display result (regular bonus, big bonus (1), big bonus) accompanied by a transition to a special gaming state that is more advantageous to the player than the normal gaming state according to the judgment result of the range judging means (2)) and a pre-determining means for determining whether or not to allow derivation of a plurality of types of winning display results including the general winning display results (cherry, watermelon, bell, replay) other than the special display results (step S1004) To S1013),
Range specifying data storage means (ROM 113, FIG. 18) for storing a plurality of range specifying data determined so that each of the plurality of types of determination value ranges can be specified;
The range specifying data storage means includes
When it is determined that the determination numerical data input in the determination area is included, it is possible to specify a range of determination values determined by the prior determination unit to permit the derivation of the special display result. Special range specifying data storage means (FIG. 18: bonus winning determination table) for storing special range specifying data determined to be;
It is possible to specify a range of determination values determined to allow the derivation of the general winning display result by the pre-determining means when it is determined that the determination numerical data input is included in the determination area General range specifying data storage means (FIG. 18: small role winning determination table) for storing general range specifying data determined to be
The range determination means includes
Special range determining means (step S1010 to S1013),
It is determined whether or not the same numerical value data for determination used for determination by the special range determination unit is included in the range of the determination value specified by the general range specification data stored in the general range specification data storage unit General range determination means (steps S1004 to S1007)
The pre-determining means is determined when both the special range determining means and the general range determining means determine that the numerical value for determination is included in the range of determination values corresponding to each of them (FIG. 18: Regular bonus) + Cherry, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Regular Bonus + Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon Range), Special Display Results and General It is characterized by deciding to allow the derivation of both winning display results.

  In the slot machine of another invention, it is determined that the derivation of both the special display result and the general winning display result is permitted when the determination numerical data input to the determination area is included in the overlapping range. It will be. In this case, even if the general winning display result is derived as the display result of the variable display device based on the determination that the deriving of the general winning display result is one of the determinations, the special display result is allowed to be further derived. It may be decided to do so. As a result, the player's sense of expectation for the derivation of the special display result can be increased, and the interest of the game can be improved.

The slot machine of another invention is
When the special display result is not derived based on the determination that the derivation of the special display result is allowed by the pre-determining means, the special determination is carried over from the next game until the special display result is derived. A carry-over means (step S810) may be further provided. In this case,
Regardless of whether or not the decision to allow the derivation of the special display result is carried over by the special decision carry-over means (there is no judgment step as in step S1009), the general range judgment means has the judgment numerical value. Determining whether the data is included in the range of the determination value specified by the general range specifying data stored in the general range specifying data storage means;
The special range determination means is on condition that the decision to allow the derivation of the special display result is not carried over by the special decision carry-over means (step S1009 (NO)), and the numerical value data for determination is the special data It can be determined whether or not it is included in the range of the determination value specified by the special range specifying data stored in the range specifying data storage means.

  In this case, it is not necessary to basically change the process when the predetermination means makes a decision depending on whether the decision to allow the derivation of the special display result is carried over, and the derivation of the winning display result is allowed. It is possible to efficiently determine whether or not. In addition, when the decision to allow the derivation of the special display result is carried over, the decision by the special decision means is not required, so that the process is simplified.

In the slot machine of another invention, the general winning display result includes a first general winning display result (cherry) and a second general winning display result (watermelon),
The range of determination values specified by the general range specifying data stored in the general range specifying data storage means is a range of determination values determined to permit the derivation of the first general winning display result. A first overlap range (FIG. 18: regular bonus + cherry, big bonus (1) + cherry, big bonus (2) + cherry) that is a range of determination values that overlap with the range of determination values specified by the special range specifying data. Range), a range of determination values that is determined to permit the derivation of the second general winning display result, and a range of determination values that overlaps with the range of determination values specified by the special range specifying data The second overlapping range (FIG. 18: Regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon range), the first general winning display A first single range (FIG. 18: cherry only) that is a range of determination values that are determined to permit the derivation of results and that do not overlap with the range of determination values specified by the special range specifying data And a range of determination values that are determined to permit the derivation of the second general winning display result and that do not overlap with the range of determination values specified by the special range specifying data A certain second single range (FIG. 18: range of watermelon only) may be included. In this case,
The ratio between the number of determination values included in the first overlapping range and the number of determination values included in the first non-overlapping range is the number of determination values included in the second overlapping range and the second non-overlapping range. It is preferable that the ratio is different from the ratio to the number of determination values included in.

  In this case, the derivation of the special display result is allowed both when the first general winning display result is derived as the display result of the variable display device and when the second general winning display result is derived. We can expect to be decided. However, the ratio between the number of determination values included in the first overlapping range and the number of determination values included in the first single range is determined by the number of determination values included in the second overlapping range and the determination included in the second single range. Since it is different from the ratio to the number of values, it is also determined that the special display result is allowed to be derived when the first general winning display result is derived and when the second general winning display result is derived. The possibilities are different. Since the player can be given a different sense of expectation with respect to the decision to permit the derivation of the special display result due to the difference in the general winning display result thus derived, the interest of the game can be improved.

In the slot machine of another invention,
The general winning display result is a replay display result (replay) accompanied by a regame that can be played without using a valuable value that can be used for setting the bet amount as a display result of the variable display device. And a re-game high probability state (RT) in which the game state is different from the special game state and the pre-determining means determines that the re-game display result is allowed to be derived with a higher probability than the normal game state. Including replay high probability display result (cherry, watermelon) with the transition of the game state to
The range of determination values specified by the general range specifying data stored in the general range specifying data storage means is a range of determination values determined to permit the derivation of the replay display result. Overlapping range that overlaps the range of the judgment value specified by the range specifying data (FIG. 18: regular bonus + cherry, regular bonus + watermelon, big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (2 ) + Cherry, Big Bonus (2) + Watermelon Range). In this case,
The slot machine of another invention is
Re-game high probability state control means (steps S708, S712) for shifting the game state to the re-game high probability state when the re-game high probability display result is derived as the display result of the variable display device;
When the special display result is not derived based on the determination that the derivation of the special display result is allowed by the pre-determining means, the special determination is carried over from the next game until the special display result is derived. Carryover means (step S810);
Stop operation means (stop buttons 12L, 12C, 12R) for instructing to stop the variable display of the identification information in the variable display device by the player's operation;
It is determined that the derivation of both the special display result and the replay high probability display result is permitted, and the special display result and the replay high probability display result are determined according to the operation timing of the stop operation means. When both can be derived, the replay high probability display result is derived with higher probability than the special display result (FIG. 8: Tables No. 3, 4, 5, and 7), and the special display result and the replay are displayed. When it is determined that the derivation of both of the display results is permitted and both the special display result and the replay display result can be derived according to the operation timing of the stop operation means, Deriving control means (steps S1014 and S405) for deriving the game display result with a high probability (FIG. 8: Table No. 9);
When the replay high probability state control means has shifted to the replay high probability state, the replay high probability effect (bonus squeezing effect) is executed by the effect means (liquid crystal display 4). Production control means (step S905) can be further provided.

  In this case, when the determination numerical data input to the determination area is included in the overlapping range, it is determined that both the special display result and the replay high probability display result are allowed, so the display result of the variable display device When the replay high probability display result is derived, it is highly possible that the special display result is permitted to be derived together with the replay high probability display result. Thereby, it is possible to increase the player's expectation that it is determined that the derivation of the special display result is permitted. This player's expectation can be further enhanced by the re-game high probability production by the re-game high probability production control means. However, a special display result is derived immediately after the replay high probability display result is derived, or a display result is derived that indicates that it is not decided to permit the special display result. However, it is not possible to sufficiently improve the interest of the game by raising the player's expectation.

  In contrast, when the re-game display result is derived, the game state is shifted to the re-game high probability state. In the replay high probability state, the display result is determined so that the replay display result can be derived with a higher probability than the normal game state, and the replay display result is derived with a higher probability than the special display result. Therefore, it is possible to control the display result so as to prevent the display result from being derived as much as possible. Thus, in a game in the replay high probability state after the replay high probability display result is derived, the game is digested without knowing whether the player is allowed to derive the special display result. By doing so, the player's expectation can be continued during this time, and the interest of the game can be improved. Moreover, the replay high-probability effect that is continuously executed during this period can increase the player's expectation and further enhance the interest of the game.

Another invention slot machine,
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of permissible stages (settings) with different probabilities that the predetermination means determines that the derivation of the winning display result is permitted. Value), an allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages,
Data storage means (RAM 112) for storing data for controlling the progress of the game including data indicating the allowable stage set by the allowable stage setting means in a readable and writable manner;
Stored data determination means (steps S104 and S105) for determining whether or not the data stored in the data storage means is normal;
Disabling means (step S106 (NO), step S301) for disabling the progress of the game when the stored data determination means determines that the data stored in the data storage means is not normal;
In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. It is possible to further include disabling canceling means (step S111, FIG. 11) for canceling the disabled state and allowing the game to proceed.

  Conventionally, when the data stored in the data storage means (RAM) in the slot machine is broken, the game cannot be progressed. The data in the data storage means is initialized by a predetermined reset operation. It was released above and the game progress was resumed. Here, when the data in the data storage means is initialized by a reset operation, the default permissible stage (usually the permissible stage with the lowest probability of being determined to permit the derivation of the winning display result) is automatically performed. Was to be selected. For this reason, the pre-determining means may not be determined with the probability that the amusement store has intended, and it is disadvantageous to the player especially when it is automatically selected at the allowable stage with the lowest probability. There was a problem that would become larger.

  On the other hand, even in the slot machine according to another invention, when the data stored in the data storage means is not normal, the game cannot be progressed properly because the game cannot be progressed properly. It is necessary to initialize the data stored in the data storage means in order to cancel the state where the game cannot be progressed here. In this case, the data indicating the allowable stage is also initialized. End up. However, in the slot machine, the state in which the game cannot be progressed based on the data in the data storage means being normal is canceled unless a new allowable stage is set based on the operation of the setting operation means. There is nothing. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

In this case,
When the determination by the range determination unit is performed, the predetermining unit reads data indicating the allowable level stored in the data storage unit, and the data indicating the read allowable level is read by the allowable level setting unit. Permissible stage data determining means (steps S1002 and S1003) for determining whether or not the data is appropriate data indicating a settable allowable stage may be included. here,
The disabling means can disable the progress of the game even when the allowable stage data determination means determines that the data indicating the allowable stage read from the data storage means is not appropriate data ( Step S1003 (NO), step S301).

  Here, even when the determination is made by the range determination means included in the prior determination means, the allowable stage stored in the data storage means is read out to determine whether the allowable stage is appropriate. If the allowable stage 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 allowable stage stored in the data storage means is not within an appropriate range, a new allowable stage must be set based on the operation of the setting operation means. It will not be released. For this reason, since it is ensured that the game is played based on the newly set allowable stage, the fairness of the game can be achieved.

Another invention slot machine,
Based on the operation of predetermined setting operation means (setting key switch 92, setting switch 91), a plurality of types of permissible stages (settings) with different probabilities that the predetermination means determines that the derivation of the winning display result is permitted. Further, an allowable stage setting means (steps S201 to S210) for selecting and setting one of the allowable stages from (value) may be further provided. In this case,
The range specifying data storage means includes
A first storage area for storing first range specification data among the plurality of range specification data in common for the plurality of types of allowable stages (FIG. 5: regular bonus + cherry, regular bonus + watermelon, big bonus (1) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Cherry, Big Bonus (2) + Watermelon, JACIN, JAC, Watermelon, Bell, Replay),
A second storage area for individually storing second range specifying data different from the first range specifying data among the plurality of range specifying data for each type of the permissible stage (FIG. 5: regular bonus, big bonus (1 ), Big bonus (2), cherry).

In this case,
The second storage area includes the same number of storage areas (FIG. 5: regular bonus) for individually storing range specifying data capable of specifying the same determination value range regardless of the allowable stage type, and the allowable stage type. It is possible to include different number storage areas (FIG. 5: Big Bonus (1), Big Bonus (2), Cherry) for individually storing range specifying data that can specify different determination value ranges depending on the case.

  Here, in the range specifying data storage means, since the first range specifying data is stored in common in a plurality of types of allowable stages in the first storage area, the storage capacity required for storing the range specifying data is small. I'll do it. On the other hand, in the second storage area, the second range specifying data is individually stored for each type of allowable stage.

  The pre-determining means determines the derivation of the winning display result according to the range specifying data determined according to the permissible stage. If the range specifying data is different, it is determined that the derivation of the winning display result is allowed. Probability will be different, but in development models, it is normal to perform simulation while finely adjusting this range specification data (the same as when the original range specification data is different) It may be left as a thing). The appropriate range specifying data obtained as a result of the simulation is applied to a model for mass production.

  Here, even if there is the range specifying data that is the same regardless of the allowable stage as a result of performing the simulation while changing the range specifying data according to the allowable stage, for such range specifying data, It is sufficient to store the same number of storage areas as they are for each type of allowable stage. If there is range specifying data that differs depending on the allowable stage as a result of the simulation, it can be stored as data in the different number storage area. For this reason, since the storage mode of the range specifying data in the development model can be used as it is in the mass production model, development from the initial design stage to the mass production model can be easily performed.

  Note that storing the range specification data individually for each type of allowable level does not necessarily mean that the range specification data is stored individually for the number of types of allowable levels, but for all types of allowable levels. If the range specifying data is not stored in common, it is included in this. For example, when there are six types of allowable stages (first stage to sixth stage), the range identification data is allowed in the case where the first to third stages are common and the fourth to sixth stages are common. Each type is stored separately.

  Note that the configuration for obtaining the determination value numerical data in the slot machine of another invention has three types of configurations shown in the slot machine of the present invention described above (the slot machine described in the means for solving the problems). Either of them can be used.

  Hereinafter, a configuration example for specifically realizing the slot machine of another invention will be described. FIG. 18 is a diagram schematically showing a winning determination table used in a slot machine that specifically realizes another invention. FIG. 19 is a flowchart showing in detail a lottery process in a slot machine that specifically implements another invention. In the example shown in FIG. 18 and FIG. 19, it is assumed that there is no regular bonus lottery in the small role game in the big bonus, and other configurations and processes are the same as those of the slot machine 1 in the above embodiment. Shall.

  As shown in FIG. 18, the winning determination table includes a small role winning determination table (not shown for RT) and a bonus winning determination table for each gaming state, which are stored in the ROM 113 in advance. Here, as shown in FIG. 18A, in the normal gaming state, the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is not carried over from the previous game. Sometimes, an internal lottery is performed using both the small role table (1) corresponding to the normal gaming state and the bonus winning determination table.

  In FIG. 18 (a), the hatched range is a range in which both the non-special role and the special role are won if the random value for internal lottery is within this range. Here, for example, the regular bonus, the big bonus (1) or the big bonus (2) and the range of determination values to be won by cherries, the regular bonus, the big bonus (1) or the big bonus (2) and the watermelon The determination value range that is won in duplicate is the same size range. On the other hand, the range of determination values for winning independently for cherry and the range of determination values for winning independently for watermelon are different. In other words, the ratio of whether or not a special combination is won differs depending on whether or not at least a cherry is won and at least a watermelon is won.

  On the other hand, even in the normal gaming state, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over from the previous game, FIG. As shown in (), only the small role table (1) corresponding to the normal gaming state is used, and the internal lottery is performed. Also in RT, it is the same as that of the case of FIG. 18 (a), (b). When the gaming state is a small-bonus game with a big bonus or a regular bonus, the regular bonus, the big bonus (1), and the big bonus (2) are not drawn in the first place, so that FIG. 18 (c), (d) As shown, an internal lottery is performed using only the small role tables (2) and (3) corresponding to each gaming state.

  In the lottery process shown in FIG. 19, the process of steps S1001 to 1003 and the point of shifting to the RAM abnormality error process when it is determined in step S1003 that the set value is not in the range of 1 to 6 are described above. This is the same as the lottery process (steps S501 to S503 in FIG. 13). Further, the processing in steps S1014 to S1017 in which the winning flag setting status in the game is determined is the same as the lottery processing in the above embodiment (steps S523 to S526 in FIG. 13).

  When it is determined in step S1003 that the set value is in the range of 1 or more and 6 or less, the small combination winning determination table prepared according to the current gaming state (normal, RT, regular bonus or small combination game) The winning determination table used for the internal lottery is set (step S1004). Next, a determination value for winning each combination registered in the set small role winning determination table is sequentially compared with a random number value for internal lottery acquired in step S1001 (step S1005) and set. It is determined whether or not any combination registered in the small combination winning determination table is won (step S1006). When any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1007), and the process proceeds to step S1008. If no winning combination is won, the process proceeds to step S1008.

  In step S1008, it is determined whether the current gaming state is a regular bonus or a big bonus depending on whether a regular bonus flag or a big bonus flag is set in the RAM 112. If the current gaming state is a regular bonus or a big bonus, the process proceeds to step S1014.

  If the current gaming state is neither a regular bonus nor a big bonus, it is either a normal gaming state or an RT. In this case, the regular bonus winning flag, big bonus (1) winning flag or big bonus ( 2) It is determined whether or not the winning flag has already been set in the game before the previous time and has been carried over without winning (step S1009). If the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set, the process proceeds to step S1004.

  If none of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are set, the bonus winning determination table is set as the winning determination table used for the internal lottery (step S1010). ). Next, the determination value for winning each combination registered in the set bonus winning determination table is sequentially compared with the random value for internal lottery acquired in step S1001 (step S1011), and the set small value is determined. It is determined whether or not any combination registered in the combination determination table is won (step S1012). If any winning combination is won, the winning flag of the winning combination is set in the RAM 112 (step S1013), and the process proceeds to step S1014. If no winning combination is won, the process proceeds to step S1014.

  In this way, separate winning determination tables are prepared for special roles and non-special roles, and the random number value for internal lottery corresponds to the value that wins the special role in the normal gaming state, and non-special roles In the case of corresponding to the winning value, the special combination and the non-special combination will be won simultaneously. In this case, even if the display result of the variable display device 2 is a prize for a small role or a replay based on a winning flag for a non-special role such as a small role or a replay, the special role is still won. there is a possibility. Thereby, the player's expectation with respect to the winning of the special role can be enhanced, and the interest of the game can be improved.

  Further, even if the special combination is not won as a result of the internal lottery, there is a possibility that the small combination or replay is won, so that the player's expectation can be maintained. Furthermore, if the winning flag for the special role is not carried over from the previous game in the normal gaming state or RT, an internal lottery is performed using both the small role winning determination table and the bonus winning determination table. If the winning combination flag is carried over from the previous game, an internal lottery may be performed using only the small winning combination determination table. As a result, the normal game state and the internal lottery in RT can be performed by a simple process.

  In this modification, the random numbers for internal lottery used for the determination of winning of special roles and the random numbers for internal lottery used for determination of winning of non-special roles were the same, but different random numbers were used. Also good. Refer to the small role winning determination table according to the random number value for internal lottery corresponding to non-special role, determine whether it is winning of cherry, watermelon, bell, replay, then internal corresponding to special role It may be determined whether the regular bonus, the big bonus (1) and the big bonus (2) are won or not by referring to the bonus winning determination table according to the random number value for the lottery.

  Also, in this modification, when the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over from the previous game in the normal gaming state or RT, the small bonus winning is performed. An internal lottery was performed using only the judgment table. On the other hand, whether the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is carried over, in the normal gaming state or RT, for small role winning determination When a lottery is performed using both the table and the bonus winning determination table, and the regular bonus winning flag, big bonus (1) winning flag, or big bonus (2) winning flag is carried over from the previous game When a regular bonus, a big bonus (1), or a big bonus (2) is won, the winning may be invalidated.

  In this modification, the winning determination table is used, and the lottery of each combination is performed by comparing the determination value registered in this table with the winning determination table. However, as in the above-described embodiment, The special combination and the special combination are added to the random numbers for internal lottery separately, and the determination value of each combination is sequentially added (may be subtracted), and when the combination overflows, it can be determined that the combination is won. However, in order to win the same determination value as when the winning determination table of FIG. 18 is used, it is also necessary to register a loss as a lottery target in the table. Further, the acquired random numbers for internal lottery may be saved for the special lottery before the non-special lottery is performed first.

  In the above embodiment, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried over from the previous game, the random number value for the internal lottery is the regular bonus. In the case of corresponding to the determination value corresponding to both the big bonus (1) or the big bonus (2) and the cherry or the watermelon, the winning of the cherry or the watermelon is assumed, but it may be lost. .

  In order to realize this example, in the lottery process of FIG. 13, if the determination result of step S513 is YES and the determination result of step S517 is YES, the process proceeds to step S523 as it is. Good. Further, in the lottery process of the modified example of FIG. 19, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is set in step S1009, the same as steps S1010 to S1012 is performed. When it is determined that there is a winning combination, if the winning flag of the cherry or watermelon is set without setting the winning flag of the winning combination, it may be deleted.

  Even in this modified example, it is not necessary to change the internal lottery process basically depending on whether the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is already set. It can be done efficiently.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set in the previous game, the small bonus winning flag is set in duplicate. Less. For this reason, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag is carried forward, it is often possible to win early, or the carry-over is known early by derivation of the reach. As a result, the game can be smoothly progressed, and it is possible to prevent a decrease in the willingness to play due to not knowing whether or not the bonus has been won forever.

  In the above embodiment, in the winning combination table by gaming state, regular bonus + cherry, regular bonus + watermelon, regular bonus, big bonus (1) + cherry, big bonus (1) + watermelon, big bonus (1), Big bonus (2) + cherry, big bonus (2) + watermelon, big bonus (2), cherry, watermelon, bell, replay role was registered, but this order is arbitrary Each lottery may be performed in any order. Further, in the modified examples of FIGS. 18 and 19, the special role lottery is performed after the non-special role lottery is performed first, but the non-special role lottery is performed after the special role lottery is performed. It is good.

  In the above embodiment, the ratio of winning a special role is different between at least winning a cherry and at least winning a watermelon, but regular bonus, big bonus (1), big The ratio of winning bonus (2) was the same. The same applies to the modified examples of FIGS. On the other hand, for example, at least when the watermelon is won, the ratio of winning the special combination may be different for each of the regular bonus, the big bonus (1), and the big bonus (2). That is, the number of determination values of regular bonus + watermelon, big bonus (1) + watermelon, big bonus (2) + watermelon may be different.

  Here, for example, when the number of determination values of big bonus (1) + watermelon or big bonus (2) + watermelon is larger than the number of determination values of regular bonus + watermelon, when winning a watermelon, it is more The player can expect to win the big bonus (1) or the big bonus (2) with high value. In this way, when the player wins a watermelon, the player can be further improved in interest by giving the player a different sense of expectation regarding the difference in the types of special roles.

  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.

  FIG. 20 is an explanatory diagram of a first modification of the process (step S101) 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. Also in the first modification, the random number extracted from the random number generation circuit 115 is stored in the 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 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The lower byte value of the general register 111GR (the value extracted from the lower counter 115b) is left as it is.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and 8080h. 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, and sequentially adds the number of determination values to this.

  FIG. 21 is an explanatory diagram of a second modification of the process (step S101) 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. Also in this example, the random number extracted from the random number generation circuit 115 is stored in the 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 further extracts the value of the internal refresh register 111R as a processing random number. The CPU 111 adds the processing random number extracted from the refresh register 111R to the value of the upper byte of the general-purpose register 111GR (the value extracted from the upper counter 115c). The processing random number extracted from the refresh register 111R is also added to the lower byte value (the value extracted from the lower counter 115b) of the general-purpose register 111GR.

  Next, the CPU 111 performs an AND operation on the value of the general-purpose register 111GR, that is, a value obtained by adding a processing random number to the upper byte and the lower byte, respectively, with 8080h. 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, and sequentially adds the number of determination values to this.

  In the first and second modified examples described above, the value of the refresh register 111R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 115 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 111R, no special configuration is required as means for generating the processing random numbers. Moreover, since the value of the refresh register 111R is updated every time the CPU 111 fetches an instruction, and the update interval is not constant, a random number with high randomness can be extracted as a processing random number. Since the random number for processing is high in randomness, the randomness of random numbers for internal lottery generated using this is also increased.

  In the first and second modified examples, the value extracted from the refresh register 111R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 115. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 111R (or a value replacing the refresh register 111R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, during the period from the extraction of the random number from the random number generation circuit 115 to the end of processing, the interrupt to the CPU 111 is prevented in order to prevent the contents of the general-purpose register 111GR from being rewritten. It will be prohibited.

  Further, in the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 115 may be separately extracted from the refresh register 111R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be configured by the refresh register 111R.

  In both the above embodiment and the first and second modifications, the seventh and fifteenth bits are masked to generate a random number for internal lottery. That is, the random number value for internal lottery is represented by 14 bits and takes a range of 0 to 16383. However, the value represented by 16 bits can be directly applied as a random number for internal lottery without masking the 7th and 15th bits. In this case, the number of determination values for each target part of the internal lottery may be registered in the ROM 113 according to the range of values that the random numbers for internal lottery can take.

  On the other hand, if the random numbers for internal lottery are generated by masking the seventh and fifteenth bits as in the above embodiment and the first and second modifications, the masked two bits Can be applied as a random number for making a decision different from the internal lottery (for example, selection of the type of effect). Thereby, all the bits of the random number extracted from the random number generation circuit 115 can be used effectively.

  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 RAM parity at power-off and the RAM parity at startup are compared to determine whether or not the data stored in the RAM 112 is normal. It may be determined whether or not the data is normal. For example, when a voltage drop signal is input due to power-off or the like, a checksum of the data in the RAM 112 (the sum total of the data strings) is created and the checksum area (area corresponding to the parity area 112-7) is created. At the same time as storing, a checksum of data in the RAM 112 may be created and compared with the checksum stored in the checksum area to determine whether or not the data in the RAM 112 is normal. In addition, a cyclic code such as CRC may be used.

  In the above embodiment, the RAM 112 is initialized before shifting to the setting change process. However, the RAM 112 may be initialized in accordance with the shift to the setting changing process. For example, the setting changing process is performed. It may be performed after the end of the process, or may be performed when the set value is confirmed in the setting change process.

  In the above embodiment, in the small game in the normal gaming state, RT, and big bonus, the game can be started only by setting 3 as the bet number. On the other hand, even in the small game in the normal gaming state, RT and big bonus, it is possible to start the game by setting 1 as the bet number, and further set 2 as the bet number. The game may be started.

  When 1 or 2 is set as the bet number in the small game in the normal gaming state, RT and big bonus, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number In both cases, the number of medals to be paid out when winning a small role can be increased. For example, when 3 is set as the bet number in the small game in the normal gaming state, RT, and big bonus, the win probability of the bell is 1 / 4.6 and the number of payout medals is 8. When 1 or 2 is set, the winning probability of the bell may be 1 / 240.9 and the number of medals to be paid out may be 15. Furthermore, the winning probability of the bell and the number of medals to be paid out may be changed depending on whether the bet number is set to 1 or 2 (the winning probability is higher when the bet number is 2 and the number of payout medals). Is more likely with 1 bet).

  Further, in a slot machine that can set any one, two, or three betting numbers in the small game in the normal gaming state, RT, and big bonus, the number of determination values is common to all of the setting values 1 to 6. There may be a combination that is stored in common for all of the 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. When the number of determination values is individually stored according to the number of bets, the same determination value number may be stored individually or different determination value numbers may be stored individually.

That is, the slot machine further includes bet number setting means (step S2) for setting any bet number for each game from among a plurality of types of bet number stages determined as the predetermined number of bets. If
In the range specifying data storage means, the first storage area includes a first common area for storing the first range specifying data in common with the plurality of types of betting number stages, and a plurality of types of allowable stages. And the first individual area for storing the first range specifying data.
Also, the second storage area is individual for each type of the permissible stage, and the second common area that stores the second range specifying data in common with the plurality of betting number stages, and the permissible stage It is good also as what contains the 2nd separate field which memorizes the 2nd range specific data for every kind and every kind of the number of betting steps.
Here, the first individual area and the second individual area are the same number area for individually storing range specifying data capable of specifying the same determination value range regardless of the betting number stage type, and the betting number. It is possible to specify a range of different determination values according to the type of stage, and it is possible to include a different number area region that individually stores range specifying data.

  In this case, by storing the range specifying data in common regardless of the number of betting steps, the storage capacity required for the range specifying data storage means can be reduced. In addition, since it is normal to perform simulation while finely adjusting the range specification data depending on the type of bet number stage in the development model, by allowing the existence of the same number area and different number area, Since the storage mode of the judgment value data in the development model can be directly used in the mass production model, the development from the initial design stage to the mass production model can be easily performed.

  Note that storing the range specifying data individually according to the type of betting number stage does not necessarily mean that the range specifying data is stored individually for the number of types of betting number stages, but for all betting numbers. If the range specifying data is not stored in common with the type of stage, it is included in this. For example, when there are 3 types (1, 2 or 3) of bet number stages, the bet number stages are common to 1 and 2, and 3 is individual. It will be memorized individually.

  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. On the other hand, based on the current symbol position when the stop condition is met and the setting status of the winning flag, pull-in control is performed so that the winning symbols are aligned, or the symbol of the winning symbol is not selected 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 for a role with a winning flag set (determined from the symbol of the role that is given priority for derivation in the case of duplicate winning), select the symbol for winning the winning combination and select the active line (already stopped) When there is a reel, the winning display mode can be derived together with the symbols on the reels that are stopped. 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 periphery, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, it is also possible to use a device that virtually displays a symbol on a display device such as a liquid crystal display device instead of the variable display device 2 as described above.

The second storage area has the same number of storage areas for individually storing range specifying data indicating the same number of determination values regardless of the type of the allowable stage, and the number of determination values different depending on the type of the allowable stage. A different number storage area for individually storing the range specifying data shown,
The pre-determining means includes
Data indicating the number of determination values respectively indicated by a plurality of range specifying data stored in the range specifying data storage means corresponding to the types of allowable steps set by the allowable step setting means, sequentially, in the determination area Subtracting means for subtracting from the judgment numerical data input to
When the subtraction result of the subtracting means exceeds the predetermined range, the numerical value data for determination input to the determination area is data indicating the number of determination values when the predetermined range is exceeded. Range determining means for determining to be included in the range of the determination value specified by the specified range specifying data,
It is determined whether or not the derivation of the plurality of types of winning display results is allowed according to the determination result of the range determination means, and the determination numerical data input to the determination area is specified by the overlapping range specifying data. When it is determined by the range determination means that it is included in the range of determination values, it is determined that derivation of both the special display result and the general winning display result is permitted.
