Abstract

<P>PROBLEM TO BE SOLVED: To enhance the amusement of the play by allowing a player to participate in the prevention of termination of a disadvantageous game state disadvantageous to the player, and to reduce the sense of loss of the profit lost by avoiding the control to the disadvantageous state. <P>SOLUTION: The play is controlled in an RT2 game state with extremely high probability of winning the replay if one of three options A1-A3 is won in the normal game state, while the play is controlled in an RT1 game state with lower probability of winning the replay if one of three options B1-B3 is won. If an RT navigation lottery is won during a big bonus game state just before the current game round in the normal game state, the information indicating which of the three options B1-B3 is won when any one of the three options B1-B3 is won. If winning of the three options B1-B3 is avoided according to the announced information, a chance for the control in the RT2 game state instead of the RT1 game state is continued, and furthermore, a chance symbol combination which may be extracted when a bonus is won is extracted as the result of display in a variable display device. The number of tokens lost because of the failure in winning the three options B1-B3 is only three. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a slot machine, and more particularly to control from an initial gaming state to a disadvantageous state that is shifted according to a display result of a variable display device.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  When a symbol of bonus combination such as a regular bonus or a big bonus is derived in the winning display mode, the game state is controlled to a bonus game state that is more advantageous to the player than the normal game state. By controlling the game state different from the normal game state such as this bonus, the game is sharpened and the interest of the game is improved. Here, in order for a winning combination including a bonus combination to occur, generally, if an internal lottery performed in advance (usually when the start lever is operated) is won and the winning flag is not set. Don't be.

  In addition to the normal game state and the bonus game state, the specific game state is advantageous to the player. For example, there is an RT that increases the probability of winning a replay in an internal lottery, which is significantly higher than the normal gaming state, and further improves the fun of gaming. Here, it is assumed that the RT symbol of “BAR-BAR-BAR” is derived to the variable display device as an opportunity to control the gaming state in RT, and this RT symbol is won in the RT lottery performed following the internal lottery. There is a slot machine that is derived on the condition that it is satisfied (see, for example, Patent Document 1).

JP-A-2005-131323 (paragraphs 0034, 0040, 0041, etc.)

  Here, the RT symbol is derived on the condition that the stop button is operated in a predetermined procedure when the role to which the RT symbol is assigned (for example, a predetermined type of small role) is won by internal lottery. If the RT symbol is missed when the winning combination is won, the benefit of controlling the gaming state to RT is also a dividend other than control to the RT (for example, the role to which the RT symbol is assigned is of a predetermined type). In the case of a small combination, the player also loses the profit due to the provision of a medal payout by winning a predetermined type of small combination. However, if information indicating that the RT symbol is assigned to the role assigned to the player is notified to the player, the player does not dare to miss the RT symbol unless an operation error is made. Profit will not be lost as long as proper stop operation is performed.

  On the other hand, as in the case of controlling the gaming state advantageous to the player by deriving a specific symbol, such as when the gaming state is controlled by RT by deriving the RT symbol, The game state may be controlled to be disadvantageous for the player. In this case, if a winning combination assigned to a specific disadvantageous symbol is awarded, the player suffers from the disadvantage of being controlled in an unfavorable gaming state. On the other hand, if a particular disadvantageous design is missed, a profit due to the awarding of a payout for a role to which the specific disadvantageous design is assigned will be lost.

  If the player is informed of information indicating that a role with a specific disadvantageous symbol has been elected, the player either dares to miss the particular disadvantageous symbol and avoids control to an unfavorable gaming state, Alternatively, it is necessary to select whether to derive a particular disadvantageous symbol and obtain a dividend for the combination to which the symbol is assigned. For this reason, if the player is informed of information indicating that a role to which a specific disadvantageous symbol is assigned is notified to the player, in any case, the player may feel a sense of loss of profit. End up.

  The present invention improves the interest of the game by allowing the player to intervene in the game with respect to avoiding the control to the disadvantaged state for the player, and suppresses the sense of loss of the profit lost by avoiding the control to the disadvantaged state. An object of the present invention is to provide a slot machine that can handle such a situation.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using a game value (medal), and a variable display device (variable display device 2) that displays a plurality of types of identification information in a variable manner. ) Is a slot machine (slot machine) in which one game is completed by deriving the display result and winning can be generated according to the display result derived to the variable display device,
Initial gaming state control means (steps S306, S307, S311, S315, S317: RT1 counter, which controls the gaming state to the initial gaming state (normal gaming state, RT3) when a predetermined initial condition is established. When the value of the RT2 counter is decremented to 0, it enters the normal gaming state)
Before the display result of the variable display device is derived for each game, the special display result (regular bonus, big bonus (1)) with the transition to the special gaming state (regular bonus, big bonus) advantageous to the player , Big Bonus (2)) and derivation of winning display results including advantageous display results (three choices A1 to A3) and a plurality of types of disadvantage display results (three choices B1 to B3) different from the special display results are permitted. Pre-determining means for determining whether or not (step S3);
Stop operation means (stop buttons 12L, 12C, 12L) operated by the player to stop the variation display of the identification information;
Derivation control means (step S4) for causing the variable display device to derive a display result in accordance with a determination result of the prior determination means and an operation procedure of the stop operation means;
A payout award means (step S302) for giving a predetermined payout when any of the plurality of types of disadvantage display results is derived as the display result of the variable display device;
Special gaming state control means (steps S208, S210, S212) for controlling the gaming state to the special gaming state when the special display result is derived as the display result of the variable display device;
Advantageous state control means (step S215) for controlling the gaming state to an advantageous state (RT2) advantageous to the player when the advantageous display result is derived as the display result of the variable display device in the initial gaming state;
When any one of the plurality of types of disadvantage display results is derived as the display result of the variable display device in the initial gaming state, the game is more advantageous than the advantageous state, apart from the provision of a predetermined payout by the payout giving means. An unfavorable state control means (step S217) for controlling the gaming state to an unfavorable state (RT1) disadvantageous to the person;
When a predetermined condition (RT navigation flag is set) is established in the initial gaming state, when the prior decision means determines that the derivation of any kind of disadvantageous display result is permitted, the type A disadvantage avoidance procedure notifying means (step S438) for notifying the player of information (types of three alternatives B1 to B3) that can specify an operation procedure for avoiding the derivation of the disadvantage display result of
When the disadvantage display result is derived as the disadvantage display result, the payout awarding means has a gaming value (3) that is equal to or less than a maximum number (3) of bets that can be set for one game as the predetermined payout. The game value giving means (step S302) for giving the player a player) and the next game can be played with the same bet number without using the game value for setting the bet number as the predetermined payout Replay granting means for granting a replay to be (a modified example when applied to a design that causes Replay A to Replay C to be controlled by RT1),
The derivation control means includes
As an operation procedure for deriving a predetermined type of disadvantageous display result, a predetermined operation procedure (“red 7” for the 3rd choice B1, “white 7” for the 3rd choice B2, “BAR” for the 3rd choice B3 is derived to the left reel 3L. The operation procedure excluding the predetermined operation procedure from all the operation procedures that can be performed by the player when the variable display device derives the display result other than the predetermined type of disadvantageous display result Established as an operation procedure for deriving the disadvantageous results,
When it is determined by the pre-determining means that derivation of the first type of disadvantage display result among the plurality of types of disadvantage display results is allowed, and the stop operation procedure is operated in the first procedure, the first type is displayed. When the stop operation means is operated in a procedure other than the first procedure, a display result other than the first type of disadvantage display result including a predetermined special allowable display result (chance eye) is obtained. First disadvantageous display result deriving means for deriving;
When it is determined by the pre-determining means that derivation of the second type of disadvantage display result among the plurality of types of disadvantage display results is allowed, and the stop operation means is operated in the second procedure, the second type is displayed. When the stop operation means is operated in a procedure including the first procedure other than the second procedure, display results other than the two types of disadvantage display results including the special permissible display result are derived. Second disadvantageous display result deriving means for deriving;
It is determined that the derivation of the special display result is permitted by the pre-determining unit, and the special display result is derived when the stop operation unit is operated in a predetermined special procedure, and the procedure is performed in a procedure other than the special procedure. Special derivation control means for deriving a display result other than the special display result including the special permissible display result when the stop operation means is operated.

  In the slot machine, if any kind of disadvantageous display result is derived as the display result of the variable display device in the initial gaming state, the gaming state is controlled to the disadvantageous state for the player. The disadvantage display result is determined according to the type of the disadvantage display result determined to allow the derivation when the derivation of the disadvantage display result is determined by the predetermining means in the initial gaming state. It is derived by operating the stop operation means in the operation procedure. Here, when it is determined that the derivation of any kind of disadvantageous display result is permitted by the predetermined determination result when the predetermined condition is established in the initial gaming state, the derivation of the disadvantageous display result of the type is derived. Information that can specify an operation procedure to avoid is notified to the player.

  When such information is notified, the player can operate the stop operation means in accordance with the notified information to avoid derivation of the disadvantage display result, so that the initial gaming state is not controlled without being disadvantageous. The player can intervene in the game by his / her own operation to continue the game, and the interest of the game can be improved. In addition, since the operation procedure of the stop operation means for deriving the disadvantage display result differs depending on the type of the disadvantage display result, the operation procedure of the stop operation means for avoiding the derivation of the disadvantage display result is constant. In addition, the player's sense of intervention in the game is increased, and the interest of the game can be improved. Further, since there is no operation procedure of the stop operation means that can always avoid any kind of disadvantageous display result, the importance of the information notification by the disadvantage avoidance procedure notification means increases.

  In addition, when the derivation of the disadvantage display result that controls the initial gaming state according to the information notified by the disadvantage avoidance procedure notification means is avoided, the player loses the payout obtained by the derivation of the disadvantage display result. However, the payout obtained by deriving the disadvantageous display result is the same without giving game value less than the maximum number of bets that can be set for one game or using the game value for setting the number of bets. It is only granting a replay that enables the next game to be played with the number of bets. For this reason, the profit lost to the player by avoiding the derivation of the disadvantageous display result is equal to or less than the maximum number of bets that can be set for one game, and the player's sense of loss of profit does not increase.

  In addition, in the case where derivation of the disadvantageous display result that causes the initial gaming state to be controlled according to the information notified by the disadvantageous avoidance procedure notifying means is avoided, the derivation of the special display result is permitted as the display result of the variable display device. A special permissible display result is derived that can also be derived when is determined. Thereby, the player can also expect that it is determined that the derivation of the special display result is permitted, and the interest of the game can be improved.

  The disadvantage display result is a small role display result when the game value is given by the game value granting means, and the display result is given the regame by the regame granting means. If it is, it will be a re-game display result.

  Further, the information that can specify the operation procedure for disadvantageous derivation of the disadvantageous display result may be a notification of the type of the disadvantageous display result determined to permit derivation. Moreover, it is good also as what alert | reports the identification information which comprises the disadvantageous display result of the kind determined to permit derivation, and the identification information arrange | positioned in the vicinity. If the disadvantageous display result determined to allow derivation and the identification information constituting it are notified, the operation procedure of the stop operation means from which the disadvantageous display result is derived can be known, and other operational procedures are disadvantageous. It can be understood that this is an operation procedure for avoiding the derivation of the display result.

  Further, when a variable display device is configured from a plurality of variable display units and a plurality of stop operation means are provided for each variable display unit, a disadvantageous display result is derived according to the order of operating the plurality of stop operation means. In the case of being performed or not derived, the order of operating a plurality of stop operation means may be used. Types of disadvantageous display results and stop operation means are information that is not relevant on the surface (for example, characters and background images displayed on the image display device). May be specified by the player (for example, the first operation procedure can be specified if the background image is red, and the second operation procedure can be specified if the background image is white).

  In addition, if the disadvantageous state is a gaming state which is more disadvantageous for the player than the advantageous state, it does not matter whether the gaming state is advantageous or disadvantageous for the player over the initial gaming state.

In the above slot machine,
The prior determination means may include simultaneous determination means for simultaneously determining whether to permit the derivation of the special display result in one game and to permit the derivation of the disadvantageous display result (FIG. 5B). ): Regular Bonus + Three Choice B1, Regular Bonus + Three Choice B2, Regular Bonus + Three Choice B3, Big Bonus (1) + Three Choice B1, Big Bonus (1) + Three Choice B2, Big Bonus 1 + Three Choice B3, Big Bonus (2) + Three Choice B1, Big Bonus (2) + Three Choice B2, Big Bonus (2) + Three Choice B3).

  In this case, the player can not only expect that the derivation of the special display result is permitted by the derivation of the special allowable display result when the disadvantageous display result can be avoided. Therefore, it can be expected that it is determined that the derivation of the special display result is permitted even when the derivation of the disadvantageous display result cannot be avoided. Thereby, even if it is a case where a disadvantageous display result is derived | led-out and it is controlled to a disadvantageous state, it is not necessary to reduce a player's expectation so much, and the interest of a game can be improved further.

  Note that the simultaneous determination means that the derivation of the special display result and the derivation of the disadvantageous display result are determined at the same time is the determination that the derivation of the special display result is permitted. It does not mean that it is newly determined that the derivation of the disadvantageous display result is allowed to be carried over, but the determination that the derivation of the special display result is allowed is not carried over from the state This means that it is newly determined that the derivation of the special display result is permitted and the derivation of the disadvantageous display result is permitted.

In the above slot machine,
Whether or not the pre-determining means allows derivation of a re-game display result (replay) that allows a next game to be played without using a game value for setting the bet amount as the winning display result Decide
The advantageous state control means does not terminate the advantageous state even if it is determined that the derivation of the special display result is permitted, and when the special display result or the advantageous display result is derived, or From the start until the predetermined number of games (100 games) is consumed, the replay height is set so that the predetermination means determines that the replay display result is allowed to be derived as the advantageous state higher than the normal game state. The gaming state can be controlled to the probability state.

  Even if it is determined that the derivation of the special display result is permitted in the replay high probability state, the special display result is difficult to be derived, but when the replay high probability state that is the specific game state ends, the special display result If it has been determined that the derivation of is permitted, the special display result is easily derived. Further, there is a high possibility that the derivation of the special display result is permitted depending on the number of games in which the replay high probability state which is an advantageous state has continued. Thereby, at the end of the advantageous state, it is possible to increase the player's expectation for the control from the derivation of the special display result to the special game state, and to improve the interest of the game.

Here, the slot machine is
An image display device (liquid crystal display 4) capable of displaying an image;
In the game controlled to the specific game state, the game continues for a continuous production period longer than one game, and ends in the game where the specific game state ends (continuous production), and the game proceeds after the game ends. A plurality of types of image effect data (effect data) respectively corresponding to a plurality of types of effects by displaying an image on the image display device including a demonstration effect (demonstration effect) executed when a state that is not performed continues. Pre-stored image effect data storage means (FIG. 6: ROM 123);
Means for storing data in a readable and writable manner, an execution effect data area (execution effect data area 122-3) in which image effect data corresponding to the effect being executed among the plurality of types of image effect data is written; Image effect data including an image data area (frame buffer 122-4) in which display image data indicating an image to be displayed on the image display device created based on the image effect data written in the execution effect data area is written. Storage means (RAM 122);
According to the display image data written in the image data area, the execution of the effect by displaying the image on the image display device including the continuous effect and the demonstration effect is controlled, and the display image data written in the image data region And an effect control means (effect control board 102: CPU 121) for outputting an image signal corresponding to the image display device and displaying an image on the image display device,
The production control means includes
Continuous production determining means (step S467) for determining that the continuous production is to be started when a predetermined condition is established in the advantageous state;
When it is determined by the continuous effect determination means that the continuous effect is to be started, the image effect data of the continuous effect is read from the image effect data storage means, and the read image effect data of the continuous effect is read as the execution effect. Continuous production data writing means (step S468) for writing in the data area;
Demo effect data writing means (step S489) for reading the image effect data of the demonstration effect from the image effect data storage means after the game is over, and writing the read image effect data of the demonstration effect in the execution effect data area. ,
After the special effect data writing means writes the image effect data of the continuous effect in the execution effect data area until the advantageous effect ends, the demonstration effect data writing means is in the execution effect data area. Demo effect prohibiting means for prohibiting writing of the image effect data of the demo effect (step S465 (YES): When the game state is RT2 and the number of remaining games is three games or less, the demo invalid flag is not erased in step S456). Can be included.

  Here, it is determined that the continuous production starts before the end of the advantageous state, and the continuous production is executed in a continuous production period longer than one game until the game where the advantageous state ends. Here, when the replay high probability state which is an advantageous state is completed, if it is determined that the derivation of the special display result is permitted, the special display result is easily derived. In addition, there is a high possibility that it is determined that the derivation of the special display result is permitted immediately before the end of the advantageous state. In this way, by performing a continuous performance until the end of the advantageous state immediately before the possibility that the special display result is derived, the player's expectation for the control from the derivation of the special display result to the special gaming state is further increased. It can be increased effectively, and the fun of the game can be further improved.

  Further, since the continuous effect continues for a longer period than one game, the data amount of the image effect data of the continuous effect inevitably increases. By prohibiting the writing of the image effect data of the demonstration effect until the specific gaming state is ended after the execution of the continuous effect is determined, the image effect data of the continuous effect with a large amount of data is read from the image effect data storage means. Thus, it is possible to eliminate the overhead of writing in the execution effect data area of the image effect data storage means.

In the above slot machine,
The initial gaming state control means controls the gaming state to the initial gaming state after the special gaming state ends (steps S306, S307, S311),
The slot machine is
Effect selection means (steps S409, S410) for selecting the type of effect (characters A, B, C) executed in the special game state in accordance with an instruction from the player;
Selection effect execution means (steps S413, S450, S472) for executing the type of effect selected by the effect selection means (in-bonus effect (especially RT navigation notification)) when being controlled in the special game state; ,
When the special game state is controlled, lottery with different winning conditions depending on the type of the effect selected by the effect selecting means (when the character A is selected, 1/32 of the character B is selected by winning the bell) A lottery means (steps S420, S424, S449 (YES)) that performs a quarter for watermelon or cherry at the time of selection, and 100% for the selection of three choices A1 to A3 and three choices B1 to B3 when the character C is won. )When,
Predetermined condition establishment determining means (steps S422, S426, and S451) for determining that the predetermined condition is established in the initial gaming state after the special gaming state is ended when the lottery means is selected.
When it is determined by the predetermined condition establishment determining means that the predetermined condition is satisfied, in a mode according to the type of the effect selected by the effect selecting means (when the character A is selected, the character at the end of the big bonus RT navigation notice in the image of A, when the character B is selected, the image of the character B at the time of the next game BET, and immediately when the character C is selected, the image of the character C). Predetermined condition establishment notifying means (steps S413, S450, S472) for notifying the player can be further provided.

  Here, since the player can select the type of effect executed in the special game state by his / her own operation, the interest of the effect executed in the special game state is improved, and it is interesting to select the type of effect. Will increase. Further, when the special gaming state is controlled, it is determined whether or not a predetermined condition is established in the initial gaming state after the special gaming state is ended, and when the determination is made, the special gaming state is ended. In the initial gaming state that is controlled after this, information that can specify the operation procedure for avoiding the derivation of the disadvantageous display result is notified.

  Here, when it is determined that the predetermined condition is established after the special gaming state is ended, the fact is notified to the player by the predetermined condition establishment notifying means. Since it differs depending on the type of production selected by the above operation, the interest in selecting the production type is further increased. In addition, whether or not the predetermined condition is satisfied after the special gaming state ends is determined by lottery with different winning conditions depending on the type of performance selected by the player's own operation. Will increase further. In addition, since the selection of the type of performance in the special gaming state by the player also affects the progress of the game itself, that is, the notification of information that can specify the operation procedure for avoiding the derivation of the disadvantageous display result, It is possible to increase the sense of intervention of the player in the game, thereby improving the interest of the game.

The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function).

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

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

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

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44.

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 to be 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 configuration of the RAM 122 will be described later. The ROM 123 stores programs executed by the CPU 121 and fixed data. The effect data stored in the ROM 123 will be described later. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts. An effect stage changeover switch 67 is connected to the effect control board 102, and detection signals of these switches / sensors are input.

  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 122 of the effect control board 102 will be described. FIG. 4 is a diagram showing a configuration of the RAM 122 of the effect control board 102. As shown in FIG. The RAM 122 of the effect control board 102 is provided with at least an effect stage storage area 122-1, a game history data area 122-2, an execution effect data area 122-3, and a frame buffer 122-4.

  In the effect stage storage area 122-1, data indicating the currently selected effect stage among the effect stages of the effect by displaying the image on the liquid crystal display 4 is stored. Here, there are two types of production stages, stage 1 and stage 2. The stage 1 and the stage 2 are different in the characters appearing in the production and the types of images used for the production background. However, since the execution probabilities and execution modes of the effects are the same, there are effects of the same effect pattern for stage 1 and stage 2 respectively.

  Further, the effect stage is switched alternately between the stage 1 and the stage 2 by the operation of the effect stage switching button 17 by the player. However, in the case of the game from the operation of the start lever 11 to the derivation of the display result to the variable display device 2 and in the case where the continuous effect or the bonus effect (described later) is executed even if it is not in the game, Since the operation of the effect stage switching button 17 is invalidated, the effect stage cannot be switched.

  In the game history data area 122-2, the history of games so far in the slot machine 1 is stored. Examples of the game history stored in the game history data area 122-2 include the number of games executed, regular bonuses, and the number of big bonus winnings. Further, the player may include the number of medals obtained by the player in the regular bonus or the big bonus (subtracting the number of bets set by the player from the number of medals paid out).

  The execution effect data area 122-3 stores at least the effect data (see FIG. 6) of the currently executed effect. As the effects executed in the slot machine 1, a bonus winning effect that is performed when a regular bonus, a big bonus, or a challenge bonus is won, and each game when the gaming state is controlled by the regular bonus, the big bonus, or the challenge bonus are performed. There is an effect during bonus, but since the effect during bonus is performed following the bonus prize effect, these effect data are prepared in advance as bonus effect data. In addition, as an effect executed in the slot machine 1, there is a continuous effect that is continuously performed until the RT2 is finished after the remaining number of games in RT2 becomes three. Production data for continuous production is also prepared in advance as continuous production data.

  The execution effect data area 122-3 has a capacity capable of storing at least either bonus effect data or continuous effect data. However, the execution effect data area 122-3 does not have a capacity for storing demonstration effect or history display effect (both described later) along with bonus effect data or continuous effect data. If there is not enough free space to store the effect data for the newly executed effect in the execution effect data area 122-3, the effect data for the effect that has been newly executed has been written so far. The data is overwritten.

  The frame buffer 122-4 is an area where image data of the currently executed effect is developed in accordance with the effect data written in the execution effect data area 122-3. The liquid crystal display 4 displays an image according to the image data developed in the frame buffer 122-4. The frame buffer 122-4 has two frames, and a moving image can be displayed on the liquid crystal display 4 by alternately switching between writing and reading image data for each frame period.

  In this way, the effect data stored in the ROM 123 is read out, written once in the execution effect data area 122-3, and then expanded into the frame buffer 122-4. This is because the speed of reading data from the RAM 122 is faster than the speed of reading from the ROM 123, so that it takes less time to read and write data as a whole.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The type of winning combination is determined according to the gaming state. In addition to the normal gaming state, the gaming state includes regular bonuses and big bonuses as special gaming states, and RT1, RT2, and RT3 as replaying high probability states that the replay winning probability is higher than the normal gaming state. There is.

  The types of winning combinations can be broadly divided into special roles with transition to special gaming status (regular bonus, big bonus), small roles with payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. FIG. 5A is a view for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when the combination of “BAR-BAR-Red 7” is aligned on any winning line in the normal gaming state, RT1, RT2, RT3. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. When a regular bonus is won at RT1, RT2, RT3, RT1, RT2, RT3 are terminated. 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 (1) is won when the combination of “red 7-red 7-red 7” is aligned on any winning line in the normal gaming state, RT1, RT2, RT3. The big bonus (2) is awarded when a combination of “white 7-white 7-red 7” is aligned on any of the winning lines in the normal gaming state, RT1, RT2, RT3. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus. When the big bonus (1) or the big bonus (2) is won at RT1, RT2, RT3, RT1, RT2, RT3 are terminated.

  In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480. After the big bonus is over, the gaming state is controlled to RT3 for the subsequent 15 games (however, regular bonus, big bonus (1), big bonus (2), 3 choices A1 to A3, 3 choices B1) ~ Until winning B3).

  Even if the regular bonus, big bonus (1) or big bonus (2) is won in the internal lottery to be described later, “Red 7”, “White 7” and “BAR” within 5 frames for reels 3L, 3C and 3R Since these are not arranged at intervals, there is a case where these combinations are not won depending on the operating procedure of the stop buttons 12L, 12C, 12R.

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any winning line in any gaming state, and five medals are paid out. Since the “watermelons” for the reels 3L, 3C, and 3R are not arranged at intervals of 5 frames or less, even if the watermelon is won in the internal lottery that will be described later, the operation of the stop buttons 12L, 12C, and 12R Depending on the procedure, you may not win.

  A bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line in any gaming state. When winning the bell, 10 medals are paid out. Since the “bells” are arranged at intervals of 5 frames or less for all of the reels 3L, 3C, 3R, when the bell is selected alone, the operation procedure of the stop buttons 12L, 12C, 12R is concerned. Without winning the bell.

  Cherry is awarded when the symbol “Cherry” is derived on any winning line for the left reel 3L in any gaming state, and two medals are paid out per winning line. When “cherry” is stopped at the upper or lower stage of the left reel 3L, the derivation is made on two pay lines, so that a total of four medals are paid out.

  The three choices A1 are awarded when a combination of “red 7-bell-ANY” (ANY represents any symbol) is aligned on any winning line in any gaming state. The three choices A2 are awarded when a combination of “white 7-bell-ANY” is aligned on any winning line in any gaming state. The third choice A3 is awarded when the combination of “BAR-Bell-ANY” is aligned on any winning line in any gaming state.

  The third choice B1 is awarded when a combination of “red 7-JAC-ANY” (ANY represents any symbol) is aligned on any winning line in any gaming state. The third choice B2 is awarded when the combination of “White 7-JAC-ANY” is aligned on any winning line in any gaming state. The three choice B3 is awarded when the combination of “BAR-JAC-ANY” is aligned on any winning line in any gaming state.

  When one of the three choices A1 to A3 and the three choices B1 to B3 is won, three medals are paid out. In addition, when the normal gaming state or one of the three choices A1 to A3 is won in RT3, the gaming state is controlled by RT2, and any of the three choices B1 to B3 is controlled in the normal gaming state or RT3. When winning, the gaming state is controlled by RT1. In other cases, the gaming state is not controlled by RT1 and RT2.

  In the internal lottery to be described later, the three choices A1 to A3 and the three choices B1 to B3 are elected alone, and the case where the regular bonus, the big bonus (1), or the big bonus (2) are both won. There is. Even if three choices A1 to A3 and three choices B1 to B3 are won in an internal lottery to be described later, “red 7”, “white 7”, and “BAR” are arranged at intervals of 5 frames or less on the reel 3L. Since it is not a translation, depending on the operation procedure of the stop buttons 12L, 12C, 12R, there is a case where these winning combinations are not won.

  When the three choices A1 to A3 and the three choices B1 to B3 are won and the winning combination is not won by the operating procedure of the stop buttons 12L, 12C, and 12R, a chance chance (losing from the viewpoint of winning) is derived. There is a case. Opportunities are the case where you have won the 3rd choice A1 to A3, 3rd choice B1 to B3 and regular bonus, big bonus (1) or big bonus (2), regular bonus, big bonus (1) or It can also be derived when the big bonus (2) is won alone. As will be described later, when any of the three choices A1 to A3 and the three choices B1 to B3 is won, the stop buttons 12L, 12C, which can remove the prize regardless of which one is won. There is no 12R operation procedure.

  Replay is awarded when the combination of “JAC-JAC-JAC” is aligned on any winning line in the normal gaming state, RT1, RT2, RT3. When a replay is won, there is no payout of medals, but the next game can be started again without setting the number of bets, so 3 medals corresponding to the number of bets 3 that are not required to be set in the next game are paid out Is essentially the same. Since “JAC” is arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when the replay is won, regardless of the operation procedure of the stop buttons 12L, 12C, and 12R. Replay winning a prize.

  As will be described later, a regular bonus, a big bonus (1) or a big bonus (2) win is carried over and a small role (watermelon, bell, cherry, three choices A1 to A3, three choices B1 to B3) Or replay. The replay is derived in preference to the regular bonus, the big bonus (1) or the big bonus (2), so there is no loss, but the regular bonus, the big bonus (1) or the big bonus (2 ) Will be prioritized.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each combination described above 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 65535) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  In the internal lottery, the number of judgment values registered for each game state and set value for each combination is sequentially added to the random number for internal lottery. It is judged that it was won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in the ROM 113 in the winning combination table by gaming state.

  FIG. 5B is a diagram showing a winning combination table by gaming state. The winning combination table by game state is stored in advance in the ROM 113, and is a table in which the number of determination values for each lottery target for each gaming state in the internal lottery is registered. Here, only a predetermined set value is shown, but a slightly different value is registered according to a difference in the set value. In the internal lottery, a plurality of combinations may be subject to lottery at the same time.

  In accordance with this winning state-specific winning table, in the internal lottery, regular bonus, regular bonus + 3 choice A1, regular bonus + 3 choice A2, regular bonus + 3 choice A3, regular bonus + 3 choice B1, regular bonus + 3 choice B2 , Regular bonus + 3 choice B3, big bonus (1), big bonus (1) + 3 choice A1, big bonus (1) + 3 choice A2, big bonus 1 + 3 choice A3, big bonus (1) + 3 choice B1 , Big Bonus (1) + Three Choice B2, Big Bonus 1 + Three Choice B3, Big Bonus (2), Big Bonus (2) + Three Choice A1, Big Bonus (2) + Three Choice A2, Big Bonus (2) + 3 choice A3, big bonus (2) + 3 choice B1, big bonus (2) + 3 choice B2, big bonus (2) + 3 choice 3, watermelon, bell, cherry, Three-option A1, three-option A2, three-option A3, a three-option B1, three-option B2, three-option B3, the determination value number of replay is obtained in accordance with the gaming state in order.

  However, for regular gaming (including when offered during a big bonus), regular bonus, regular bonus + 3 choice A1, regular bonus + 3 choice A2, regular bonus + 3 choice A3, regular bonus + 3 choice B1, regular bonus + 3 choice B2, regular bonus + 3 choice B3, big bonus (1), big bonus (1) + 3 choice A1, big bonus (1) + 3 choice A2, big bonus 1 + 3 choice A3, Big Bonus (1) + Three Choice B1, Big Bonus (1) + Three Choice B2, Big Bonus 1 + Three Choice B3, Big Bonus (2), Big Bonus (2) + Three Choice A1, Big Bonus (2) + 3 choice A2, big bonus (2) + 3 choice A3, big bonus (2) + 3 choice B1, big bonus (2 + Three-option B2, for big bonus (2) + three-option B3, 0 as the determination value of the number of replay has been registered, may not be elected to these roles.

  In the normal gaming state or RT3, when one of the three choices A1 to A3 is elected, if the player knows which of the three choices is elected, the stop button 12L is set so that the player can win the three choices A1 to A3. Can be operated, and the gaming state can be controlled by RT2. On the other hand, if you do not know which of the three choices A1 to A3 is won, no matter how high the player's skill is, he will miss the three choices A1 to A3 at a certain rate, and the three choices A1 Even if ~ A3 is won, RT2 cannot control the gaming state.

  Further, when one of the three choices B1 to B3 is elected, if the player knows which of the three choices B1 to B3, the player can operate the stop button 12L so as to avoid winning the three choices B1 to B3. It is possible to prevent the gaming state from being controlled by RT1. On the other hand, if you don't know which of the three choices B1 to B3 is won, you can avoid winning the three choices B1 to B3 at a certain rate no matter how high the player's skill is. However, the gaming state is controlled by RT1.

  In addition, in the setting value in the example of FIG. 5B, the regular bonus and the big bonus in the case of including the normal game state, the overlapping selection of the three choices A1 to A3 and the three choices B1 to B3 in RT1, RT2, and RT3. (1) The total number of determination values of the big bonus (2) is 438, and the probability of winning either the regular bonus, the big bonus (1) or the big bonus (2) is 438/65536. The reciprocal 65536/408 (≈149.6) is larger than the RT1 continuous game number 144.

  Further, the number of replay determination values in the normal gaming state, RT1, RT2, and RT3 is the same for each set value. However, the total number of replay determination values is 8932 in the normal gaming state, whereas it is 8983 in RT1, 50604 in RT2, and 38542 in RT3. The replay winning probability in RT1 is not substantially different from the normal gaming state, and is approximately 1 / 7.3. On the other hand, the replay winning probability in RT2 is approximately 1 / 1.4. The replay winning probability in RT3 is approximately 1 / 1.7.

  By setting the replay winning probability in this manner, in the normal gaming state and RT1, the medal payout rate is smaller than 1 (that is, the internal lottery with respect to the number of medals inserted for setting the bet number). In RT2 or RT3, the replay winning probability is higher in RT2 or RT3, so that the medal payout rate becomes larger than 1 (that is, the number of bets). The number of medals to be paid out for the small role won in the internal lottery is larger than the number of medals to be inserted for the setting of). However, the medal payout rate in RT2 is also smaller than the medal payout rate in the regular bonus (including the big bonus). The relationship of the medal payout rates according to the gaming state described here is the same when the set value is any of 1-6.

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R constituting the variable display device 2 rotate on condition that the start lever 11 is operated and a predetermined time has passed since the start of rotation of the reels 3L, 3C, and 3R in the previous game. Be started. When the stop buttons 12L, 12C, and 12R are operated by the player, the corresponding reels 3L, 3C, and 3R are within the maximum stop delay time range of 190 milliseconds (4 frames pull-in range). In)).

  The reels 3L, 3C and 3R stop rotating so that the winning symbol set in the winning line is aligned on the winning line within the range of the maximum stop delay time of 190 milliseconds, and the maximum stop of 190 milliseconds It is controlled so that the symbol of the combination for which the winning flag is not set within the delay time is not aligned on the winning line.

  Here, when the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag and the replay winning flag are set to overlap, the replay symbols are preferentially aligned on the winning line. Controlled. Regardless of the operation procedure of the stop buttons 12L, 12C, and 12R, the replay is won. In this case, the regular bonus, the big bonus (1), or the big bonus (2) is not won.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and watermelon winning flag or bell winning flag are set in duplicate, the regular bonus, big bonus (1) or big Control is performed so that the symbol of bonus (2) is preferentially aligned on the winning line. When the symbols of regular bonus, big bonus (1) or big bonus (2) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, the “watermelon” or “bell” "Can be aligned on the winning line," watermelon "or" bell "can be aligned on the winning line and the watermelon or bell can be awarded.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and cherry winning flag are set in duplicate, the regular bonus, big bonus (1) winning flag or big bonus ( 2) Control is performed so that the winning flag pattern is preferentially aligned on the winning line. When the symbols of the regular bonus, big bonus (1) winning flag or big bonus (2) winning flag cannot be aligned on any winning line according to the operating procedure of the stop buttons 12L, 12C, 12R, If the “cherry” can be derived to the upper or lower stage of the reel 3L, the “cherry” is derived to the upper or lower stage to win the cherry.

  Regular Bonus Winning Flag, Big Bonus (1) Winning Flag or Big Bonus (2) Winning Flag and Three Choice A1 Winning Flag, Three Choice A2 Winning Flag, Three Choice A3 Winning Flag, Three Choice B1 Winning Flag, Three Choice B2 Winning Flag Alternatively, when the three-choice B3 winning flag is set in an overlapping manner, first, the regular bonus, the big bonus (1) or the big bonus (2) is preferentially controlled so as to be aligned on the winning line. . If the symbols of regular bonus, big bonus (1) or big bonus (2) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, the three choices A1 to A3, three Control is performed so that the symbols of the options B1 to B3 are preferentially arranged on the winning line.

  When the symbols of the three choices A1 to A3 and the three choices B1 to B3 cannot be aligned on the winning line by the operation procedure of the stop buttons 12L, 12C, and 12R, the control is performed so that the symbols of chance chances are aligned. Only the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag is set, and the regular bonus, big bonus (1) or big bonus (by the operating procedure of the stop buttons 12L, 12C, 12R ( Even when the symbols of 2) cannot be aligned on any winning line, the control is performed so that the symbols of chance chances are aligned.

  Only the three choice A1 winning flag, the three choice A2 winning flag, the three choice A3 winning flag, the three choice B1 winning flag, the three choice B2 winning flag or the three choice B3 winning flag are set, and the stop buttons 12L, 12C, 12R are set. If the winning procedure of the three choices A1 to A3 and the three choices B1 to B3 can be aligned on the winning line, the three choices A1 to A3 and the three choices B1 to B3 are used as the winning line. Controlled to align to the top. When the symbols of the three choices A1 to A3 and the three choices B1 to B3 cannot be aligned on the winning line by the operation procedure of the stop buttons 12L, 12C, and 12R, the control is performed so that the symbols of chance chances are aligned.

  Here, for example, when aligning the symbols of the three choices A1 to A3 on the winning line, when the reel 3L on the left side of the reel 3C in the middle is stopped first, “red 7”, “white 7” or The symbol corresponding to the winning one of “BAR” can be stopped at either the upper stage or the lower stage. Thereafter, when the reel 3C in the middle is stopped, the “bell” can be stopped at an arbitrary position, so that “red 7” and “white 7” are selected according to the winning one of the three choices A1 to A3. ”Or“ BAR ”is led out to the left reel 3L, the player always wins one of the three choices A1 to A3.

  When the inner reel 3C is stopped before the left reel 3L, the “bell” of the reel 3C is stopped at the middle stage. Thereafter, when the left reel 3L is stopped, the symbol corresponding to the winning one of “red 7”, “white 7” or “BAR” can be stopped at either the upper stage or the lower stage. As long as “Red 7”, “White 7” or “BAR” can be derived to the left reel 3L according to the winning choices of the three choices A1 to A3, be sure to win one of the three choices A1 to A3. .

  For the left reel 3L, for example, if the three-choice A1 is won and the stop button 12L is operated at the timing when the “bell 7” from the “12” to the “red 7” from the 18th is positioned in the lower row, the “red 7 Is derived. If the three-choice A2 is selected and the stop button 12L is operated at the timing when the “white 7” of the 11th is positioned in the lower row from the “watermelon” of the 5th, “white 7” is derived. If the third choice A3 is won and the stop button 12L is operated at the timing when the 19th “JAC” to the 4th “BAR” are located in the lower stage, “BAR” is derived.

  Even when the three choices B1 to B3 are elected, the same control as the case where the three choices A1 to A3 are elected, except that “JAC” is derived instead of “bell” for the inner reel 3C. Is done. However, since either “red 7”, “white 7” or “BAR” is derived for the left reel 3L regardless of the operation timing of the stop button 12L, the selection of the three choices B1 to B3 is made. Regardless, there is no operating procedure for the stop buttons 12L, 12C, and 12R that can avoid winning of any of these combinations.

  Note that the stop control of the reels 3L, 3C, and 3R described above is based on the stop operation position of the reels that have not yet stopped according to the gaming state and the setting state of the winning flag (and the symbols derived for the reels that have already stopped). A stop control table that defines the relationship between the stop position and the stop position is created in advance for unreacted reels, and when the stop buttons 12L, 12C, and 12R are operated, the stop control table created in advance is referred to and The rotation of the reel to be stopped is to be stopped. In the stop control table, the stop position is uniquely determined with respect to the stop operation position.

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

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

  The BET command indicates that the bet number for one game has been determined, and is transmitted when 3 is set as the bet number (including automatic setting based on a replay winning). The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The winning information command indicates the type of winning generated according to the display result of the variable display device 2 and the number of medals to be paid out with the winning. The display result is derived to the variable display device 2 and the winning determination is made. Sent when done. The gaming state command indicates a gaming state to be applied in the next game. When the gaming state is at RT2, the remaining number of games is 4 games or more, 3 games, 2 games, and 1 game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As such an effect, RT that notifies the player that the normal gaming state or RT3 is difficult to be controlled from RT3 to RT1, and informs the player of information for facilitating control by RT2, or RT that notifies the player that RT navigation is to be performed. There is a navigation notice. The RT navigation notification is performed when the gaming state is in the big bonus, and is part of the effect during the big bonus.

  When the gaming state is a regular bonus or a big bonus, a bonus medium effect according to the type of bonus is performed. The effect during bonus is performed by updating the image displayed on the liquid crystal display 4 for each game until the bonus is ended, except when performing RT navigation notification (limited to during the big bonus). When a regular bonus or a big bonus is won, a bonus winning effect is performed according to the stage selected separately from the bonus effect and the type of bonus that has been won. The execution mode of the bonus winning effect and the medium bonus effect varies depending on the type of bonus and the effect stage stored in the effect stage storage area 122-1.

  Further, when the number of remaining games in RT2 becomes 3 or less, a continuous effect is performed. The continuous effect is performed by updating the image displayed on the liquid crystal display 4 for each game until the end of RT2. The execution mode of the continuous production is determined by whether the regular bonus, the big bonus (1) or the big bonus (2) is won when the remaining number of games in RT2 becomes 3, and the production stage storage area 122-1. It differs depending on the stage stage that is stored. In addition, there are a plurality of patterns depending on whether the regular bonus, the big bonus (1), or the big bonus (2) is won.

  Further, the CPU 121 of the effect control board 102 performs a history display effect for displaying the game history stored in the game history data area 122-2 on the liquid crystal display 4 based on the operation of the player's effect stage switching button 17. It is. In the history display effect, not only the game history is simply displayed as information, but the CPU 121 further performs an operation for advancing the game for a predetermined period or longer (however, the reel 3L, The liquid crystal display 4 performs a predetermined demonstration effect except when the game is in progress from the start of rotation to the stop of 3C and 3R).

  The effect performed by displaying the image on the liquid crystal display 4 other than the RT navigation, which will be described in detail later, is the effect data stored in the ROM 123 in the execution effect data area 122-3, and the image data corresponding to the written effect data Is expanded in the frame buffer 122-4, and an image corresponding to the expanded image data is displayed on the liquid crystal display 4.

  Data corresponding to the type of each bonus for causing the liquid crystal display 4 to display images in the bonus winning effect and the bonus medium effect for each effect stage is stored in advance in the ROM 123 as bonus effect data. In addition, data corresponding to various continuous effect patterns for displaying a continuous effect image on the liquid crystal display 4 for each effect stage is stored in advance in the ROM 123 as continuous effect data. Further, the effect data of the history display effect and the effect data of the demonstration effect are stored in the ROM 123 in advance. FIG. 6 is a diagram showing the configuration of various effect data stored in the ROM 123.

  As shown in the figure, regular bonus effect data for performing regular bonus winning effects and regular bonus effects, big bonus effect data for performing big bonus winning effects and big bonus effects, and continuous effects in various patterns. Are produced for each stage of stage 1 and stage 2 and stored in the ROM 123. In addition, demonstration effect data and history display effect data are prepared in common with stage 1 and stage 2 and stored in ROM 123.

  Here, the bonus winning effect and the bonus medium effect (including the RT navigation notification) are effects continuously executed over a period of a plurality of games of each game during the bonus from the time of winning the bonus. This is an effect that is continuously executed over a period of up to three games until the end of RT2. Accordingly, the bonus effect data and the continuous effect data have a larger data amount than the effect data of the demonstration effect and the history display effect.

  As described above, since the bonus effect data and the continuous effect data have a large amount of data, the continuous effect and the bonus are not included in the period from the operation of the start lever 11 to the derivation of the display result to the variable display device 2. When the medium effect is being executed, a demonstration invalid flag is set in the RAM 122, and the operation of the effect stage switching button 17 is invalidated. Thereby, during the execution of the continuous effect and the bonus effect, the effect stage is not switched, and the effect data of the effect stage that is different in the middle is not written again in the execution effect data area 122-3. Further, since the demonstration effect and the history display effect are invalidated, the effect data of the demonstration effect and the history display effect is not overwritten on the bonus effect data or the continuous effect data and written in the execution effect data area 122-3.

  The RT navigation can be shifted to RT2 where the payout rate of medals is larger than 1 for 100 games only when the gaming state is controlled in the normal gaming state or RT3. Three choices B1 to B3 when the A3 is won and when the payout rate of medals is almost the same as the normal gaming state for 144 games, and there is no chance to move to RT2. When the player is elected, a sound indicating which of the types is won is output from the speakers 7L, 7U, 7R to notify the player.

  When the RT navigation is performed, for example, when it is notified that the three-choice A1 is won, the player operates the stop button 12L at the timing when “red 7” is derived to the left reel 3L. Thus, it is possible to control the RT 2 which is advantageous to the player by winning the third choice A 1. Further, for example, when it is notified that the three-choice B1 is won, if the player operates the stop button 12L at a timing at which “red 7” is not derived to the left reel 3L, the three-choice B1 Without winning a prize, it is possible to avoid the control to RT1 which is disadvantageous to the player.

  In addition, the RT navigation is not necessarily performed if the gaming state is controlled by the normal gaming state or RT3, but it is determined that the RT navigation is performed. When it is not decided to perform RT navigation, when the game state is controlled by the normal game state or RT3 and three choices A1 to A3 or three choices B1 to B3 are won, three choices A1 to A3 or three One of the options B1 to B3 is notified that the player has won, but the sound that is not shown until which one is won is output from the speakers 7L, 7U, and 7R. When it is determined that RT navigation is to be performed, RT navigation notification is performed.

  Whether or not to perform RT navigation is first determined when the gaming state has a big bonus, and when it is determined that RT navigation is to be performed, RT navigation notification is performed as part of the bonus medium effect. There are three types of triggers for determining whether or not to perform RT navigation in the big bonus game state, and which of the triggers is selected by the player at the start of the big bonus.

  That is, before the first game of the big bonus is started, the three types of characters A, B, and C are switched and displayed for a certain period of time on the liquid crystal display 4, and the number of bets for the first game of the big bonus is displayed. The character switching display is stopped at the timing when the player performs the determining operation. The type of the character stopped here is a trigger for determining whether to perform RT navigation. In addition, the selection of the character type makes a difference in the effect during the big bonus performed during the big bonus even if the effect stage is the same.

  When the character A is selected and the winning probability is 54100/65536, winning a bell, RT navigation lottery for determining whether or not to perform RT navigation is performed. The winning probability of the RT navigation lottery here is 1/32. In addition, even if the RT navigation lottery is won in this case, the RT navigation notification is not performed immediately, and the image of the character B is displayed on the liquid crystal display 4 as part of the bonus medium effect at the end of the big bonus. RT navigation notification will be performed.

  When the character B is selected, RT navigation lottery for determining whether or not to perform RT navigation is performed when either a cherry with a winning probability of 6200/65536 or a watermelon with a winning probability of 300/65536 is won. The winning probability of the RT navigation lottery here is 1/4. In addition, when the RT navigation lottery is won in this case, the image of the character B is displayed on the liquid crystal display 4 as a part of the bonus effect when the number of bets set for the next game is determined. Thus, RT navigation notification is performed.

  When the character C is selected, the winning probabilities are 820/65536, which are either the three choices A1 to A3 or the three choices B1 to B3. Based on this, the three choices A1 to A3 and the three choices B1 to B3 are selected. When winning a prize, it is determined that RT navigation is performed with 100% probability without passing through the RT navigation lottery. In this case, immediately after winning the three choices A1 to A3 and the three choices B1 to B3, the image of the character C is displayed on the liquid crystal display 4 as part of the bonus effect, and RT navigation notification is performed. Become. In addition, when the character C is selected and one of the three choices A1 to A3 and the three choices B1 to B3 is won, the liquid crystal display 4 performs a turning effect.

  Furthermore, if it is not decided to perform RT navigation in a game that has consumed more than 700 games after the regular bonus or big bonus game state ends, the fact that RT navigation notification is automatically performed (that is, 100%) Is determined). In this case, RT navigation notification is performed at that time. Since the RT navigation notification here is not an effect during bonus, it is not a display of an image on the liquid crystal display 4.

  The RT navigation notification during the big bonus or at the end of the big bonus is performed by displaying a predetermined image on the liquid crystal display 4 as an effect during the big bonus, which is selected by the player at the start of the big bonus. This is done by displaying an image of a character of a type according to the stage of production. The RT navigation notification that is performed after the completion of the regular bonus or the big bonus with 700 games or more is not displayed on the liquid crystal display 4 but by, for example, lighting the game effect lamps 75A to 75M in a predetermined manner. Done.

  In addition to the effect stage storage area 122-1, the game history data area 122-2, the execution effect data area 122-3, and the frame buffer 122-4 shown in FIG. An area for setting an RT navigation flag indicating that RT navigation has been determined and RT navigation notification has already been performed is provided. The RT navigation flag is deleted when the game state is controlled from the next game to regular bonus, big bonus, RT1 or RT2.

  When it is determined that RT navigation is performed when the character A or character B is selected in the big bonus, the RT navigation notification is not performed immediately. Therefore, in these cases, it is determined that RT navigation is performed. However, an area for setting an A notification flag and a B notification flag indicating that RT navigation notification has not yet been performed is also provided in the RAM 122. An area for setting the demo invalidation flag is also provided in the RAM 122. The demonstration invalid flag also indicates whether the effect stage switching button 17 is valid / invalid.

  Furthermore, since it is necessary to determine the winning situation in the RAM 122 of the effect control board 102 other than the timing of receiving the winning situation notification command, the winning situation indicated by the winning situation notification command received from the game control board 101 is stored. This area is also provided. Further, since it is necessary to determine the game state other than the timing at which the game state command is received, an area for storing the game state indicated by the game state command received from the game control board 101 is also provided. For a specific gaming state, it is necessary not only to be controlled by the game (or next game), but also to determine whether it will start or end, so the area for saving the gaming state is Two games are provided.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. In the following description, descriptions of processes not related to the present invention may be omitted.

  FIG. 7 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1).

  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. A BET process for instructing the start is performed (step S2). If the player has won a replay in the previous game, the same number of bets as in the previous game (3 in this embodiment) is automatically set by the replay game flag (the replay game flag is erased at this stage). ). When the bet number is confirmed in the BET process (that is, when 3 is set as the bet number), a BET command indicating the confirmation of the bet number is transmitted to the effect control board 102.

  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 S3). In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel rotation process is performed (step S4). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. .

  When the driving of each of the reels 3L, 3C, and 3R is stopped, a winning determination process is performed to determine whether any of the above-mentioned role symbols is derived and displayed on any winning line in the display mode at the time of stopping. (Step S5). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning information command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S6). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S3 will be described in detail. FIG. 8 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S101). If the gaming state is not the big bonus, the process proceeds to step S104 as it is.

  If the gaming state is a big bonus, it is determined whether or not the gaming state is a regular bonus depending on whether or not the regular bonus flag is set in the RAM 112 (step S102). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. A regular bonus medium flag is set to control the gaming state to a regular bonus (step S103). Then, the process proceeds to step S104. If the gaming state is a regular bonus, the process proceeds to step S104 as it is.

  In step S104, random number acquisition processing is performed, and by outputting a sampling command, the random number generated by the random number generation circuit 115 is extracted by the sampling circuit 116 and stored in the random number storage area for internal lottery in the RAM 112. The random numbers for the internal lottery may be used after being processed in a predetermined procedure by software instead of using the random numbers extracted from the random number generation circuit 115 as they are.

  Next, in correspondence with the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 5B is sequentially read (step S105). Next, the number of determination values stored in the address registered in the role-specific table corresponding to the gaming state and set value read for the lottery target is acquired (step S106). Then, the acquired number of determination values is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value (step S107). 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 S108).

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the lottery targets in the gaming state (step S109). If there is something that has not yet been processed, the process returns to step S105, and the process continues with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S117.

  If an overflow occurs, is the lottery target role read in the previous step S105 a regular bonus, a big bonus (1) or a big bonus (2) + three choices A1, A2, A3, B1, B2, or B3? It is determined whether or not (step S110). In the case of regular bonus, big bonus (1) or big bonus (2) + three choices A1, A2, A3, B1, B2 or B3, the regular bonus winning flag, big bonus (1) winning flag in RAM 112, or It is determined whether or not the big bonus (2) winning flag is set (step S111).

  If none of the regular bonus winning flag, big bonus (1) winning flag and big bonus (2) winning flag is set, the regular bonus winning flag, big bonus (1) winning flag or Big Bonus (2) Set the winning flag in the RAM 112, and set the three choice A1 winning flag, the three choice A2 winning flag, the three choice A3 winning flag, the three choice B1 winning flag, the three choice B2 winning flag or the three choice B3 winning flag. It is set in the RAM 112 (step S112). Then, the process proceeds to step S117.

  If the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is already set in the RAM 112 in step S111, the three-choice A1 winning flag, three according to the read lottery target role is read. Only the selection A2 selection flag, the three selection A3 selection flag, the three selection B1 selection flag, the three selection B2 selection flag or the three selection B3 selection flag are set in the RAM 112 (step S113). Then, the process proceeds to step S117.

  If the lottery target is not a regular bonus, big bonus (1) or big bonus (2) + three choices A1, A2, A3, B1, B2 or B3 in step S110, the lottery target is a regular bonus, big It is determined whether the bonus is (1) or big bonus (2) (step S114). If the lottery target combination is neither the regular bonus, the big bonus (1), or the big bonus (2), the process proceeds to step S116.

  When the regular bonus, the big bonus (1), or the big bonus (2) is selected, the regular bonus winning flag, the big bonus (1) winning flag, or the big bonus (2) winning flag is set in the RAM 112. It is determined whether or not (step S115). If any of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag is set, the process proceeds to step S117. If none of the regular bonus winning flag, the big bonus (1) winning flag, and the big bonus (2) winning flag are set, the process proceeds to step S116.

  In step S116, the winning flag of the lottery object combination is set in the RAM 112. Here, the lottery is not a regular bonus, a big bonus (1), or a big bonus (2), and is already a regular bonus winning flag, a big bonus (1) winning flag or a big bonus (2) winning flag. Is set, the winning flag of the current lottery target role is set over the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag already set. Then, the process proceeds to step S117.

  In step S117, a winning status notification command is generated according to the setting status of the winning flag in the RAM 112, and is transmitted to the effect control board 102. Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S5 will be described in detail. FIG. 9 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S5. In the winning determination process, the winning combination corresponding to the gaming state is read in order from the beginning (step S201). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the five winning lines of the variable display device 2 (step S202).

  If the combination of symbols for the combination is complete, a winning flag for the combination is set in the RAM 112 (step S203), and the process proceeds to step S204. If the symbol combination of the combination is not complete, the process proceeds to step S204 as it is. In step S204, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S201, and the next winning combination corresponding to the gaming state is read out.

  If all of the combinations corresponding to the game state are targeted for winning determination, it is next determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the RAM 112 (step S205). If a replay prize has been won, a replay game in-progress flag is set in the RAM 112 (step S206). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the process proceeds to step S218.

  If no replay winning is made, it is determined whether or not the big bonus (1) is won according to whether or not the big bonus (1) winning flag is set in the RAM 112 (step S207). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S208). Then, the process proceeds to step S218.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won according to whether or not the big bonus (2) winning flag is set in the RAM 112 (step S209). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S210). Then, the process proceeds to step S218.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S211). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Also, the values of the RT1 counter, RT2 counter, and RT3 counter in the RAM 112 are all initialized to 0 (step S212). Then, the process proceeds to step S218.

  If the regular bonus is not won, neither the regular bonus medium flag nor the big bonus medium flag is set in the RAM 112, and the game state in the current game depends on whether the RT1 counter and the RT2 counter are both 0. It is determined whether the game state is normal or RT3 (step S213). If the game state in the current game is neither the normal game state nor RT3, the process directly proceeds to step S218.

  If the game state in the current game is the normal game state or RT3, whether or not the three choices A1 to A3 have been won depending on whether or not the three choice A1 to A3 winning flags are set in the RAM 112 Is determined (step S214). If one of the three choices A1 to A3 is won, 101 is set as the initial value of the RT2 counter of the RAM 112 and the value of the RT3 counter is initialized to zero. Here, 101 is set instead of 100 as the number of continuing games of RT2, because the value of the RT2 counter is subtracted by 1 in the current game in step S315 (step S215). Then, the process proceeds to step S218.

  If none of the three choices A1 to A3 has been won, it is determined whether or not one of the three choices B1 to B3 has been won depending on whether or not the winning flag of the three choices B1 to B3 is set in the RAM 112 ( Step S216). If one of the three choices B1 to B3 is won, 145 is set as the initial value of the RT1 counter of the RAM 112, and the value of the RT3 counter is initialized to zero. Here, 145 is set instead of 144 which is the number of continued games of RT1, because the value of the RT1 counter is subtracted by 1 in the current game in step S313 (step S217). Then, the process proceeds to step S218. If none of the three choices B1 to B3 has been won, the process directly proceeds to step S218.

  In step S218, winning information indicating the type of winning combination based on the winning flag set in the RAM 112 (however, in the case of losing, the winning flag is not set) and the number of medals to be paid out with the winning. A command is generated and transmitted to the effect control board 102. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S6 will be described in detail. FIG. 10 is a flowchart showing in detail the payout process executed by the CPU 111 in step S6. In the payout process, it is determined whether or not there has been a small role winning accompanied by a medal payout depending on whether or not any of the watermelon, bell, cherry, three choices A1 to A3, and three choices B1 to B3 is set in the RAM 112. (Step S301). If the small role is not won, the process proceeds to step S303 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, until the number of credits accumulated as data reaches 50, instead of paying out medals, the number of credits is increased (step S302). Then, the process proceeds to step S303.

  In step S303, whether or not the game state of the game is a big bonus is determined based on whether or not the big bonus flag is set in the RAM 112. However, when the big bonus (1) or big bonus (2) winning flag is set in the RAM 112, it is a big bonus (1) winning or a big bonus (2) winning in the game, and the game Since the game state is not a big bonus, even if the big bonus medium flag is set, it is not determined that the big bonus is being performed. If the game state of the game is not a big bonus, the process proceeds to step S308.

  If it is determined that the big bonus is in progress, the counter provided in the RAM 112 counts the total number of medals paid out after the big bonus starts (step S304). As a result of this counting, it is determined whether or not the total number of paid-out medals exceeds 465 (step S305). If the total number of medals paid out does not exceed 465, the process proceeds to step S308.

  When the total number of paid-out medals exceeds 465, the big bonus medium flag set in the RAM 112 is erased and the value of the counter for counting the total number of paid-out medals is initialized to 0 (step S306). ). Since the big bonus is ended here, 15 which is the maximum number of continued games of RT3 is set in the RT3 counter of the RAM 112 (step S307), and the process proceeds to step S311.

  In step S308, it is determined whether or not the game state of the game is a regular bonus (including a case where a big bonus is provided) depending on whether or not the regular bonus flag is set in the RAM 112. However, if the regular bonus winning flag is set in the RAM 112, it is a regular bonus winning in the game, and the game state of the game is not a regular bonus, so the regular bonus flag is set. Even if it is, it is not determined that the regular bonus was in effect.

  If the game state of the game is a regular bonus, the counter provided in the RAM 112 starts the regular bonus (after a new regular bonus starts in the big bonus) The number of digested games and the number of winning games are counted (step S309). As a result of this count, it is determined whether the number of winning games in the regular bonus has become 8 or the number of digested games in the regular bonus has become 12 (step S310).

  If the number of winning games in the regular bonus is 8 or the number of digested games in the regular bonus is 12, the process proceeds to step S311. If the number of winning games in the regular bonus is not eight and the number of digest games in the regular bonus is not twelve, the process proceeds to step S318. In step S311, the regular bonus flag set in the RAM 112 is erased, and the counter values for counting the number of digest games and the number of winning games in the regular bonus are both initialized to zero. Then, the process proceeds to step S318.

  If the game state of the game is not a regular bonus in step S308, it is determined whether the value of the RT1 counter in the RAM 112 is 0 (step S312). If the value of the RT1 counter is not 0, the RT1 counter value is subtracted by 1 (step S313), and the process proceeds to step S318. If the value of the RT1 counter is 0, it is determined whether or not the value of the RT2 counter in the RAM 112 is 0 (step S314). If the RT2 counter value is not 0, the RT2 counter value is decremented by 1 (step S315), and the process proceeds to step S318. If the value of the RT2 counter is 0, it is determined whether or not the value of the RT3 counter in the RAM 112 is 0 (step S316). If the value of the RT3 counter is not 0, the value of the RT3 counter is subtracted by 1 (step S317), and the process proceeds to step S318. If the value of the RT3 counter is 0, the process proceeds to step S318 as it is.

  In step S318, if the watermelon winning flag, the bell winning flag, the cherry winning flag, the three-choice A1 to A3 winning flag, the three-choice B1 to B3 winning flag, and the replay winning flag are set in the RAM 112, these are deleted. The big bonus (1) winning flag, the big bonus (2) winning flag, and the regular bonus winning flag are not erased here and are carried over to the next game. If a winning flag is set in the RAM 112 in step S203, it is deleted.

  Next, based on the big bonus medium flag and the regular bonus medium flag in the RAM 112 and the values of the RT1 counter, the RT2 counter, and the RT3 counter, a gaming state command indicating a gaming state to be applied in the next game is generated. It transmits to the control board 102 (step S319). Then, the payout process is ended, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 7, the processing in the current one game ends.

  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, RT1, RT2, RT3, regular bonus, and big bonus, and the progress of the game In response, a command is transmitted to the effect control board 102. On the other hand, based on the command received from the game control board 101, the CPU 121 of the effect control board 102 performs effects processing including bonus effects and continuous effects, selection of effects during the big bonus, and RT navigation. ing. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  11 to 13 are flowcharts 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 S201). When any command is received from the game control board 101, the time measurement by the internal timer of the CPU 121 is started again from 0 (step S402).

  Next, the effect data of the demonstration effect is stored in the execution effect data area 122-3, and based on this, it is determined whether the demonstration effect is being executed (step S403). If the demonstration effect is being executed, this demonstration effect is terminated (step S404), and the process proceeds to step S407. If the demonstration effect is not being executed, the effect data of the history display effect is stored in the execution effect data area 122-3, and based on this, it is determined whether the history display effect is being executed (step S405). If the history display effect is being executed, the history display effect is terminated (step S406), and the process proceeds to step S407. If the history display effect is not being executed, the process directly proceeds to step S407. In step S407, when any command is received from the game control board 101, the type of the received command is determined.

  If the received command type is the BET command transmitted in step S2, the game state to be started from now is referred to with reference to the two game states stored in the RAM 122 in step S452 (described later) of the previous game. It is determined whether or not it is the first game after the end of the big bonus (step S408). If it is the first game after the end of the big bonus, the character switching display started in step S459 (described later) and performed on the liquid crystal display 4 is stopped (step S409). Then, information indicating the type of the stopped character is stored in the RAM 122 (step S410). Then, the process returns to step S401.

  If the game to be started is not the first game after the end of the big bonus, it is determined whether or not the B notification flag is set in the RAM 122 by RT navigation winning in the selection of the character B (step S411). If the B notification flag is set, it is determined whether or not the watermelon or cherry has been won in the previous game with reference to the winning information indicated by the winning information command received in the previous game (step S412).

  If the watermelon or cherry is won in the previous game, RT navigation notification is given on the liquid crystal display 4 by the effect by the character B (step S413), and the process proceeds to step S414. If neither watermelon nor cherry is won in the previous game, RT navigation notification is not performed (although RT navigation is performed), the process proceeds to step S414. In step S414, the B notification flag set in the RAM 122 is erased, and an RT navigation flag is set to perform RT navigation after the end of the big bonus. Then, the process returns to step S401. If the B notification flag is not set in step S411, the process directly returns to step S401.

  When the type of the received command is the winning status notification command transmitted in step S117, the winning status indicated by the received winning status notification command (that is, the setting status of the winning flag in the current game) is stored in the RAM 122 in advance. (Step S415).

  Next, since one game is started, the history display effect and the effect stage are not switched regardless of whether or not a bonus effect or a continuous effect is being executed. The demonstration invalid flag is set to “” to invalidate the operation of the effect stage switching button 17. (Step S416). If the gaming state is a regular bonus or a big bonus, or if the number of remaining RT games is 3 games or less, the state where the demo invalid flag is set is continued as it is, so a demonstration effect is performed. No situation will only continue after the game starts.

  Next, with reference to the gaming state stored in the RAM 122 in step S452 (described later) of the previous game, it is determined whether or not the gaming state in the current game is a big bonus (step S417). If the game state in this game is a big bonus, depending on the character type stored in step S410 and the progress status of the big bonus according to the bonus effect data written in the execution effect data area 122-3 in step S445 (described later). The displayed image is displayed on the liquid crystal display 4 and an effect during the big bonus is performed (step S418).

  Next, it is determined whether or not the character type stored in step S410 is the character A and the received winning status notification command indicates that the current game has won the bell (step S419). When the character type is character A and the bell is won, a RT navigation lottery is performed by a random number lottery with a winning probability of 1/32 (step S420), and as a result, it is determined that RT navigation is performed. It is determined whether or not (step S421). If it is determined that RT navigation is to be performed, the A notification flag is set in the RAM 122 (step S422), and the process returns to step S401. If it is determined not to perform RT navigation, the process directly returns to step S401.

  If the character type is not character A, or if the winning status notification command does not indicate that the bell is won, the character type stored in step S410 is character B, and received. It is determined whether or not the winning status notification command indicates that a watermelon or cherry is won in the current game (step S423).

  If the character type is character B and the watermelon or cherry is won, RT navigation lottery is performed by random number lottery with a winning probability of 1/4 (step S424), and it is determined that RT navigation is performed as a result. It is determined whether it has been done (step S425). If it is determined to perform RT navigation, the B notification flag is set in the RAM 122 (step S426), and the process returns to step S401. If it is determined not to perform RT navigation, the process directly returns to step S401.

  If the character type is not character B, or if the winning status notification command does not indicate that watermelon or cherry is won, the character type stored in step S410 is character C, and It is determined whether the received winning status notification command indicates that one of the three choices A1 to A3 or the three choices B1 to B3 has been won in the current game (step S427).

  When the character type is the character C and one of the three choices A1 to A3 or the three choices B1 to B3 is selected, the liquid crystal display 4 performs a turning effect by displaying the image of the character C ( Step S428). Then, the process returns to step S401. If the character type is not character C, or if it does not indicate that the winning status notification command 3 choices A1 to A3 or 3 choices B1 to B3 has been won, the process directly proceeds to step S401. Return.

  If the game state of the current game is not a big bonus in step S417, the game state stored in the RAM 122 in step S452 (described later) of the previous game is further referred to, and the game state in this game is a regular bonus. It is determined whether or not (except for those provided during the big bonus) (step S429). If the game state in this game is a regular bonus, an image corresponding to the progress status of the regular bonus is displayed on the liquid crystal display 4 in accordance with the bonus effect data written in the execution effect data area 122-3 in step S445 (described later). Then, the regular bonus production is performed (step S430). Then, the process returns to step S401.

  If the game state of the current game is not a regular bonus, the game state of the current game is set to the normal game state by referring to the game state for two times stored in the RAM 122 in step S452 (described later) of the previous game. It is determined whether the game state or RT3 is in effect (step S431). If the game state in the current game is the normal game state or RT3, it is determined whether or not the received winning status notification command indicates one of the three choices A1 to A3 (including duplicate winnings) (steps) S432).

  If one of the three choices A1 to A3 is won, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S433). If the RT Navi flag is set in the RAM 122, the speaker 7L, 7R, 7U outputs a sound capable of specifying which of the three choices A1 to A3 is won, and notifies the player (step) S434). Then, the process returns to step S401. If the RT navigation flag is not set, one of the three choices A1 to A3 is won, but the voice that cannot be specified until it is won is output from the speakers 7L, 7R, 7U. The player is notified (step S435). Then, the process proceeds to step S401.

  If the received winning situation notification command does not indicate any of the three choices A1 to A3, whether the received winning situation notification command indicates any of the three choices B1 to B3 (including duplicate winning) It is determined whether or not (step S436). If any of the three choices B1 to B3 is not indicated, the process directly returns to step S401.

  If one of the three choices B1 to B3 is won, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S437). If the RT Navi flag is set in the RAM 122, the speaker 7L, 7R, 7U outputs a sound capable of specifying which of the three choices B1 to B3 is won and notifies the player (step) S438). Then, the process returns to step S401. If the RT Navi flag is not set, one of the three choices B1 to B3 is won, but the speaker 7L, 7R, 7U outputs an unidentifiable voice until it is chosen. Then, the player is notified (step S439). Then, the process proceeds to step S401.

  If the game state of the current game is neither the normal game state nor RT3, that is, RT1 or RT2, refer to the game state stored in the RAM 122 in step S452 (described later) of the previous game, It is determined whether the game state in this game is RT2 and the number of remaining games is within 3 games (step S440). If the gaming state is not RT2 (that is, the normal gaming state), or if it is RT2, the number of remaining games is 4 games or more, the process returns to step S401.

  If the game state in this game is RT2 and the number of remaining games is within 3 games, the number of remaining RT games according to the continuous effect data written in the execution effect data area 122-3 in step S468 (described later). An image corresponding to is displayed on the liquid crystal display 4, and a continuous effect for the current game is performed (step S441). Then, the process returns to step S401.

  If the received command type is the winning information command transmitted in step S218, the winning information indicated by the received winning information command is stored in a predetermined area of the RAM 122 (step S442). Further, the game history stored in the game history data area 122-2 is updated according to the result of the current game (in particular, the winning information indicated by the winning information command received here) (step S443).

  Next, it is determined whether or not the winning information indicated by the received winning information command indicates that a regular bonus or a big bonus has been won (step S444). If it indicates that a regular bonus or a big bonus has been won, the bonus stage data corresponding to the stage and the type of bonus won are read from the ROM 122 and stored in the stage stage storage area 122-1. Then, it is written in the execution effect data area 122-3 (step S445). Next, in accordance with the bonus effect data written here, a bonus winning effect among the bonus effects is performed on the liquid crystal display 4 (step S446). Then, the process returns to step S401.

  If it is not indicated in step S444 that either the regular bonus or the big bonus has been won, refer to the gaming state for two times stored in the RAM 122 in step S452 (described later) of the previous game. It is determined whether or not the gaming state is a big bonus (step S447). If the gaming state in the current game is a big bonus, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S448).

  If the RT navigation flag is not set, whether or not the character type stored in step S410 is character C, and the received winning information command indicates winning of three choices A1 to A3 or three choices B1 to B3. Is determined (step S449). If one of the three choices A1 to A3 or the three choices B1 to B3 has been won, a predetermined image of the character C is displayed on the liquid crystal display 4 indicating that RT navigation is to be performed after the end of this big bonus. This is notified to the player (step S450). Further, an RT navigation notification flag is set in the RAM 122 (step S451). If the character C is selected and the three choices A1 to A3 or the three choices B1 to B3 are won, RT navigation is performed with a probability of 100% after the end of the big bonus. This is essentially the same as winning the 100% RT Navi lottery. Then, the process returns to step S401.

  If the game state in the current game is not a big bonus in step S447, if the RT navigation flag has already been set in the RAM 122 in step S448, or if the character type is not character C in step S449, If it does not indicate that any of the three choices A1 to A3 or the three choices B1 to B3 has been won, the process directly returns to step S401.

  If the received command type is the gaming state command transmitted in step S319, the gaming state stored in the gaming state storage area for two games in the RAM 122 is shifted (received in the previous game). The gaming state indicated by the gaming state command is evicted), and the gaming state indicated by the gaming state command received in the current game is stored (step S452). Next, it is determined whether or not the game state of the next game indicates a big bonus or a regular bonus (step S453).

  If the game state of the next game is a big bonus or a regular bonus, the value of the inter-bonus game counter in the RAM 122 is initialized to 0 (step S454). Further, with reference to the game state for two times stored in the RAM 122, it is determined whether or not a regular bonus (not including those provided in the big bonus) or a big bonus starts from the next game (step S455). If neither a regular bonus nor a big bonus is started from the next game, the process returns to step S401.

  When a regular bonus or a big bonus starts from the next game, whether or not the RT navigation flag is set in the RAM 122, that is, a new regular bonus or big bonus starts without being controlled by RT1 or RT2 after the end of the big bonus (Step S456). If the RT navigation flag is not set, the process proceeds to step S458 as it is. If the RT navigation flag is set, the RT navigation flag is deleted from the RAM 122 (step S457), and the process proceeds to step S458.

  In step S458, it is determined whether the big bonus starts from the next game instead of the regular bonus. If the big bonus starts from the next game, the character switching display for switching the characters A, B, and C to be displayed on the liquid crystal display 4 for a certain period is started (step S459). Then, the process returns to step S401. If the big bonus does not start from the next game, the process directly returns to step S401.

  If the game state of the next game is neither a big bonus nor a regular bonus in step S453, the game state for two times stored in the RAM 122 is further referred to and a big bonus or a regular bonus (provided during the big bonus is provided in this game). It is determined whether the process has ended (step S460). If the big bonus or the regular bonus (not including those provided in the big bonus) has ended in the current game, it is determined whether or not the A notification flag is set in the RAM 122 (step S461).

  If the A notification flag is not set, the process proceeds to step S469. If the A notification flag is set, since the RT navigation lottery is won by the end of the big bonus with the character A selected, a predetermined image of the character A indicating that the RT navigation is performed is displayed on the liquid crystal display. 4 is displayed to the player (step S462). Further, the A notification flag is deleted from the RAM 122, and the RT navigation flag is set in the RAM 122 (step S463). Then, the process proceeds to step S469.

  If the big bonus or regular bonus (not including those provided in the big bonus) is not finished in this game, the bonus game counter value in the RAM 122 is incremented by 1 (step S464). Further, referring to the gaming state stored in the RAM 122, it is determined whether or not the gaming state of the next game is RT2 and the remaining number of games is 3 or less (step S465). If the gaming state is not RT2, or the remaining game number is 4 or more even if it is RT2, the process proceeds to step S469.

  If the number of remaining games in RT2 is 3 or less, it is further determined whether or not the number of remaining games in RT2 is 3 (step S466). If the remaining number of games in RT2 is 3, the continuous production will start from the start timing of the next game, so the production stage stored in the production stage storage area 122-1 and saved in the RAM 122 in step S415. A pattern of continuous effects is determined according to whether the winning status indicates winning of regular bonus, big bonus (1) or big bonus (2) (step S467). Then, the continuous effect data of the determined pattern is written in the execution effect data area 122-3 (step S468). Then, the process proceeds to step S470. If the remaining number of games in RT2 is not 3, since the continuous effect data has already been written, the process proceeds to step S470 as it is.

  In step S469, since the game state of the next game is not a bonus, and it is not the case where the number of remaining games is 3 or less in RT2, neither the continuous effect nor the bonus effect is performed in the next game. Become. In this case, the demonstration invalid flag set in the RAM 122 is erased, and the operation of the effect stage switching button 17 is also validated. Then, the process proceeds to step S470.

  In step S470, it is determined whether or not the value of the bonus game counter in the RAM 122 has reached 700 or more, that is, whether or not a game has been played in the normal gaming state, RT1, RT2 or RT3 for 700 games. If the value of the game counter between bonuses is 700 or more, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S9471). If the RT navigation flag is set, the process directly returns to step S901. If the RT navigation flag is not set, the game effect lamps 75A to 75M are turned on to notify the player that RT navigation will be performed again (step S472). Further, an RT navigation flag is set in the RAM 122 (step S473). Then, the process returns to step S401.

  On the other hand, if the value of the game counter between bonuses is less than 700, it is determined whether RT1 or RT2 starts from the next game with reference to the game state stored twice in the RAM 122 (step S474). . If the next RT1 or RT2 starts, it is determined whether or not the RT navigation flag is set in the RAM 122 (step S475). If the RT navigation flag is not set, the process directly returns to step S401. If the RT navigation flag is set, the RT navigation flag is deleted from the RAM 122 (step S476), and the process returns to step S401.

  If RT1 or RT2 does not start from the next game, it is determined by referring to the game state for two times stored in the RAM 122 whether RT2 has ended in the current game (step S477). If RT2 has not ended in the current game, the process returns to step S401. If RT2 is completed in this game, it is determined whether or not the R notification flag is set in the RAM 122 (step S478).

  If the R notification flag is not set, the process directly returns to step S401. If the R notification flag is set, the RT navigation lottery is won until RT2 is finished, so that a predetermined image indicating that RT navigation is to be performed is further displayed on the liquid crystal display 4. (Step S479). Further, the R notification flag is deleted from the RAM 122, and the RT navigation notification flag is set in the RAM 122 (step S480). Then, the process returns to step S401.

  If the received command type is another command, processing corresponding to each command type is executed (step S481). Since the processing here is not related to the present invention, detailed description thereof is omitted. Thereafter, the process returns to step S401.

  If it is determined in step S401 that no command has been received, it is determined whether a demo invalid flag is set in the RAM 122 (step S482). As described later, the demonstration invalid flag is displayed in the narrow sense game from the operation of the start lever 11 until the display result is derived to the variable display device 2, or even during the game, the bonus medium effect or the continuous effect is displayed. It is set when it is executed. If the demo invalid flag is set, the operation of the effect stage changeover switch 17 is also invalid, and the process directly returns to step S401 without performing the effect stage switching and the history display effect as well as the demo effect.

  If the demonstration invalid flag is not set, it is determined whether or not a short-term operation of the effect stage changeover switch 17 has been detected and the player has instructed to change the effect stage (step S483). When switching of the production stage is instructed, the production stage stored in the production stage storage area 122-1 is different from the current stage (for example, if the current production stage is stage 1, the stage 2) (Step S484). Then, the process returns to step S401.

  If switching of the effect stage is not instructed, it is determined whether or not a long-term operation of the effect stage changeover switch 17 has been detected and execution of the history display effect has been instructed by the player (step S485). When the execution of the history display effect is instructed, the effect data of the history display effect is read from the ROM 123 and written in the execution effect data area 122-3 (step S486). Further, the history display effect is started on the liquid crystal display 4 according to the effect data of the history display effect and the game history stored in the game history data area 122-2 (step S487). Then, the process returns to step S401.

  Note that starting the history display effect means that the history display effect is designated as an effect that is being executed, and thereafter, an image corresponding to the execution progress is executed by an image display routine that is started every frame period different from this flowchart. Data is developed in the frame buffer 122-4, and an image is displayed on the liquid crystal display 4 according to the developed image data. This is the same for other effects.

  If execution of the history display effect is not instructed in step S485, it is determined whether or not the internal timer of the CPU 121 has elapsed the predetermined time (step S488). If the predetermined time has not elapsed, the process directly returns to step S401. If the predetermined time has elapsed, the demonstration effect data is read from the ROM 123 and written in the execution effect data area 122-3 (step S489). Furthermore, the demonstration effect is started on the liquid crystal display 4 according to the written demonstration effect data (step S490). Then, the process returns to step S401.

  As described above, in the slot machine 1 according to this embodiment, after the regular bonus is finished, it is controlled to the normal gaming state, and after the big bonus is finished, it is changed to the normal gaming state through RT3 of 15 games. Be controlled. When winning the three choices A1 to A3 in RT3 or the normal gaming state, the gaming state is controlled to RT2, and when winning the three choices B1 to B3, the gaming state is controlled to RT1. When controlled by RT1 or RT2, it is not directly controlled by RT2 or RT1. If the 100 games are consumed at RT2 or the 144 games are consumed at RT1 without winning the regular bonus, the big bonus (1) or the big bonus (2), the game state is controlled again to the normal gaming state.

  RT2 is a game state that is advantageous to a player whose medal payout rate is greater than 1 because the winning probability of replay is significantly higher than the normal game state. This advantageous RT2 includes a stop button 12L at a timing at which “red 7”, “white 7”, and “BAR” can be derived to the left reel 3L when the three choices A1 to A3 are won in the internal lottery. It can be controlled by operating and winning. If the operation timing of the stop button 12L is not appropriate, even if the three choices A1 to A3 are won, no winning is made and the gaming state is not controlled by RT2.

  Here, if the RT navigation flag is not set in the normal gaming state or RT3, that is, if it is not determined to perform RT navigation, any of the three choices A1 to A3 is selected even if the three choices A1 to A3 are won. You will not be notified until you have won the type. In this case, since the player cannot operate the stop button 12L at the timing of reliably winning the winning one of the three choices A1 to A3, there is a possibility of causing the RT2 to control in the internal lottery. Even if it occurs, RT2 cannot be controlled at a constant rate.

  On the other hand, if the RT navigation flag is set in the normal gaming state or RT3, that is, if it is determined to perform RT navigation, any one of the three choices A1 to A3 is won. The player is notified of whether or not it is present. The player operates the stop button 12L at a timing at which one of the three choices A1 to A3 that has been notified can win a prize, thereby causing the three choices A1 to A3 to win and control the gaming state to RT2. It can be. Thereby, a player can intervene in a game by his / her own operation regarding control to RT2 which is a game state advantageous to the player, and the interest of the game can be improved.

  Further, the operation timing of the stop button 12L for winning the three choices A1 to A3 controlled by the RT2 is completely different depending on which of the three choices A1 to A3 is selected. Depending on which of the three choices A1 to A3 is won, the player must change the timing of operating the stop button 12L in order to control the RT2, so the player's sense of intervention in the game In addition, since the technicality of timing the operation of the stop button 12L when performing an operation to intervene in the game is also required, the interest of the game can be further improved.

  On the other hand, RT1 is a gaming state that is disadvantageous for a player who has a replay winning probability almost the same as a normal gaming state and whose medal payout rate is smaller than one. For this disadvantageous RT1, when the three choices B1 to B3 are won, the stop button 12L is operated at a timing at which “red 7”, “white 7”, and “BAR” can be derived to the left reel 3L. Thus, if the three choices B1 to B3 are awarded, it will be controlled. If the stop button 12L is operated at a timing at which “red 7”, “white 7”, and “BAR” cannot be derived, even if the three choices B1 to B3 are won, the three choices B1 to B3 will not be won. It is not controlled by RT1, which has no possibility of being controlled by RT2 until the end.

  Here, in the normal gaming state, if the RT navigation flag is not set, that is, it is not determined that the RT navigation is performed, any type of the three options B1 to B3 even if the three options B1 to B3 are won. You wo n’t be notified until you win. In this case, the player cannot operate the stop button 12L at a timing at which winning can be surely avoided in the three choices B1 to B3. Thus, control to RT1 cannot be avoided.

  On the other hand, if the RT navigation flag is set in the normal gaming state, that is, if it is determined to perform RT navigation, it is determined which of the three choices B1 to B3 is won. Is notified to the player. The player operates the stop button 12L at a timing at which winning of the one of the three choices B1 to B3 that is informed can be avoided, thereby controlling the gaming state to RT1 without winning the three choices B1 to B3. Can be avoided. Thus, the player can intervene in the game by his / her own operation with respect to avoiding RT1, which is a gaming state disadvantageous to the player, and the interest of the game can be improved.

  Further, the operation timing of the stop button 12L for avoiding winning of the three choices B1 to B3 controlled by RT1 is completely different depending on which of the three choices B1 to B3 is won. Since the player must change the timing of operating the stop button 12L in order to prevent the RT1 from controlling depending on which of the three choices B1 to B3 is won, further avoiding RT1 The player's sense of intervention in the game is further increased, and technical skill is also required for timing the operation of the stop button 12L when performing an operation to intervene in the game, so that the interest of the game can be further improved.

  By the way, if the three choices A1 to A3 are won and the RT navigation is not performed, or the RT operation is performed, the player mistakes the stop operation and wins the three choices A1 to A3. If not, not only missed the opportunity to control the gaming state to RT2, but also the player's profit for the medal that would have been paid out by winning the three choices A1 to A3 Will be lost.

  However, since the number of medals to be paid out by winning the three choices A1 to A3 is only three, which is the same as the number of bets set per game, the player's sense of loss of profit will not be too great. Even if you miss the three choices A1 to A3, the game state is not controlled by RT1, and if you win the three choices A1 to A3, you get a chance to control the game state to RT2 again. Therefore, the player's sense of loss of profits will not be too great.

  If you win 3 choices B1 to B3 and avoid winning 3 choices B1 to B3 to avoid control to RT1, you will be paid out by winning 3 choices B1 to B3 as a small role The player loses profits by the amount of medals. However, since the number of medals to be paid out by winning the three choices B1 to B3 is only 3, which is the same as the number of bets set per game, the player's sense of loss of profit will not be too great.

  Further, when the winning of the three choices A1 to A3 controlled to RT2 is missed or when the winning of the three choices B1 to B3 to avoid the control to RT1 is avoided, the variable display device As a display result of 2, a chance chance that can be derived when the regular bonus, the big bonus (1), or the big bonus (2) is won is derived. Therefore, even if there are profits lost due to the loss of the three choices A1 to A3 and the three choices B1 to B3, the player expects to win the regular bonus, the big bonus (1) or the big bonus (2) Since it will be possible, the interest of the game can be improved.

  Further, the three choices A1 to A3 and the three choices B1 to B3 are roles that can be won simultaneously in one game for each of the regular bonus, the big bonus (1), and the big bonus (2) in the internal lottery. For this reason, even if the three choices B1 to B3 are won and controlled by RT1, the regular bonus, the big bonus (1) or the big bonus (2) can still be expected. Become. Thereby, it is not necessary to reduce the player's expectation much by controlling to RT1 by winning three choices B1 to B3.

  Further, the maximum number of RT2 continuous games controlled based on the winnings of the three choices A1 to A3 is 100 games, and the maximum number of continuing games of RT1 controlled based on the winnings of the three choices B1 to B3 is 144 games. is there. On the other hand, the probability of winning the regular bonus, the big bonus (1) or the big bonus (2) in the normal gaming state, RT1, RT2 or RT3 is approximately 1 / 149.6. That is, the expected value of the number of games between bonuses is larger than the maximum number of continued games of RT1 and RT2.

  In particular, even if the RT1 maximum continuous game number is smaller than the expected value of the number of games between bonuses, even if it is once controlled to RT1, the next regular bonus, big bonus (1) or big bonus (2) will be won. By the time, it is controlled again to the normal gaming state, and there are many cases where the chance of controlling by RT2 comes. Therefore, the player's expectation is not greatly impaired. In addition, between the bonuses, RT1 and RT2 can be appropriately controlled.

  By the way, as described above, the winning of the three choices A1 to A3 is notified in the normal gaming state so as to be controlled by RT2, or in the normal gaming state so as to avoid the control to RT1, so that the winning of the three choices B1 to B3 is avoided. Whether or not to perform RT navigation for notifying the player is first determined when the gaming state is controlled to the big bonus. When the gaming state is controlled to the big bonus, the effect during the big bonus is performed in each game.

  Here, before the first game of the big bonus is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the first game of the big bonus is performed by the player's betting number setting operation. When the betting number for the game is determined, the character type displayed at that time is the character type applied to the big bonus medium effect. As described above, since the contents of the effect during the big bonus change depending on the selection of the character type according to the setting timing of the bet number, the fun of selecting the character type is increased.

  Further, when the big bonus is controlled to determine whether or not to perform RT navigation after the end of the big bonus, when the character A is selected, the winning of the bell is selected, and when the character B is selected, the winning of the watermelon or cherry is selected. When the character C is selected, the three choices A1 to A3 and the three choices B1 to B3 are different according to the type of the selected character. In addition, the probability that RT navigation is determined at each opportunity is also different from 1/32, 1/4, and 1/1. However, considering the winning probabilities of each combination, the probability that RT navigation will be performed before the end of the big bonus does not differ greatly regardless of which type of character is selected. Thus, since the selection of the character at the start of the big bonus affects not only mere production but also the progress of the game itself, the player's sense of intervention in the game can be enhanced, thereby improving the interest of the game. .

  Furthermore, when it is decided to perform RT navigation in the big bonus, RT navigation notification is performed to notify the player of this, but the images displayed at the time of RT navigation notification are respectively selected. This is an image of the selected character. Furthermore, RT navigation notifications are also made at the end of the big bonus when character A is selected, when the number of bets for the next game is determined when character B is selected, and when the character C is selected, three options are selected. Depending on the type of the selected character, the A1 to A3 and the three choices B1 to B3 are immediately awarded. As described above, the selection of the character at the start of the big bonus also makes a difference in the RT navigation notification method performed when it is determined that the RT navigation is performed. Will be able to.

  Furthermore, when the number of games digested after the end of the regular bonus or the big bonus is 700 games or more, RT navigation is always performed when controlled to the normal gaming state. This RT navigation makes it easier to control the RT 2 which is advantageous to the player, so that it is possible to provide relief for the excessive number of games between bonuses.

  In addition, in the game from the 3 games before the end of RT2 to the end of RT2, a continuous production is also performed. In RT2, where the last three games are played continuously, the replay winning probability derived in preference to the regular bonus, big bonus (1) or big bonus (2) is very high, so regular bonus, big bonus (1 ) Or the big bonus (2), it is difficult to win the regular bonus, the big bonus (1) or the big bonus (2). Furthermore, 97 games are consumed at RT2 until the continuous performance is started, and 100 games are consumed at RT2 until the continuous performance is completed, so regular bonus, big bonus (1) or until the end of RT2 The possibility of winning the big bonus (2) is very high.

  In the game after the end of RT2, there is a high possibility that the regular bonus, the big bonus (1), or the big bonus (2) has already been won. Since the probability is low, the possibility of winning the regular bonus, the big bonus (1) or the big bonus (2) is very high. As a result, immediately after the end of RT2, the player's expectation for winning the regular bonus, the big bonus (1) or the big bonus (2) can be increased, and the interest of the game can be improved.

  Furthermore, by performing a continuous performance immediately before the game immediately after the end of RT2, which is very likely to win the regular bonus, big bonus (1) or big bonus (2), that is, the last three games of RT2, The player's expectation for winning the regular bonus, the big bonus (1), or the big bonus (2) can be increased more effectively, and the fun of the game can be further improved.

  The bonus medium effect (and the bonus winning effect performed immediately before) when the above-mentioned gaming state is a regular bonus or a big bonus and the continuous effect performed in the last three games of RT2 are given to the liquid crystal display 4. It is performed by displaying an image, and is an effect performed over a period of a plurality of games. Bonus production and continuous production are executed at either stage 1 or stage 2 according to the player's selection, but the stage of production varies depending on the progress of the game regardless of the player's selection. is not.

  Further, although it is not an effect indicating the current progress of the game, it is not a period during the game from the operation of the start lever 11 to the derivation of the display result of the variable display device 2, and in a predetermined period, If no game operation is performed, a demonstration effect is executed. When the player instructs execution of a history display effect by long-pressing the effect stage switching button 17, the history display effect is executed. Furthermore, the stage can be switched by operating the stage switch button 17 (except for a long press) during the period between the games.

  When performing an effect performed by displaying an image on the liquid crystal display 4, it is first necessary to read the effect data of the effect to be executed from the ROM 123 and write it in the execution effect data area 122-3 of the RAM 122. There is a processing overhead required to read / write the effect data. Since the bonus effect data for performing the bonus winning effect and the effect during the bonus, or the continuous effect data for performing the continuous effect, it is necessary to execute the effect over a plurality of games. The amount of data is larger than that of the effect data, and the overhead required for reading / writing is larger than the effect data of the demonstration effect and the history display effect.

  Here, even if a bonus effect or a continuous effect is being executed, if a demo operation is not performed for a predetermined period in the period between games, the demonstration effect is then executed. Data must be read from the ROM 123 and written to the execution effect data area 122-3. In this case, since the demonstration effect production data must be overwritten on the bonus production data or continuous production data, if the demonstration production is ended by some game operation, the original bonus production production or continuous production will be resumed. Then, the bonus effect data or the continuous effect data must be read from the ROM 123 again and written in the execution effect data area 122-3. In addition to this, data indicating how far the bonus medium effect or the continuous effect has been executed at the start of the demonstration effect must be saved and restored at the end of the demonstration effect. The same applies when a history display effect is about to be executed by a long press operation of the effect stage switching button 17 by the player.

  Further, even during the execution of the bonus effect or the continuous effect, the effect stage can be switched during the period between the games, and the effect stage during the bonus or the continuous effect can be switched from there by operating the effect stage switching button 17. If this is the case, the effect data corresponding to the new effect stage must be read from the ROM 123 and written in the execution effect data area 122-3. If this is allowed, the same process must be performed many times each time the effect stage switching button 17 is operated.

  On the other hand, in the slot machine 1 according to this embodiment, the demonstration invalid flag is not erased even if one game is finished during execution of the bonus effect or the continuous effect, and the effect stage switching button 17 The operation of is also disabled. In other words, since the demonstration effect data and the history display effect data are read out from the ROM 123 and written into the execution effect data area 122-3, the bonus effect data corresponding to the bonus effect being executed, The continuous effect data corresponding to the continuous effect is not overwritten by the effect data of the demonstration effect or the history display effect and is not erased from the execution effect data area 122-3. Since it is not erased, there is no need to read out bonus effect data and continuous effect data from the ROM 123 and write them in the execution effect data area 122-3.

  For this reason, in order to execute a demonstration effect or a history display effect that is not directly related to the current game progress, bonus effect data and continuous effect data with a large amount of data are read from the ROM 123 and executed effect data in the RAM 122. The overhead of the process of writing in the area 122-3 does not occur repeatedly. Further, there is no processing overhead of saving data indicating how far the bonus medium effect or the continuous effect has been executed at the start of the demonstration effect or the history display effect, and returning the data when the demonstration effect ends.

  In addition, since the operation of the effect stage switching button 17 is also invalidated during the execution of the bonus effect or the continuous effect, the effect stage is not switched, and the same situation is dealt with only by changing the effect stage. It is possible to prevent the overhead that the effect data has to be read from the ROM 123 and written to the execution effect data area 122-3 of the RAM 122.

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

  In the above embodiment, the RT navigation notifications are all displayed on the liquid crystal display, although there is a difference in timing when any of the characters A, B, and C is selected by the player at the start of the big bonus. It was supposed to be performed by displaying an image on the device 4. However, RT navigation notification may be performed in a manner different from the display of images on the liquid crystal display 4 in some or all of the three types of characters. For example, when sound is output from the speakers 7L, 7R, and 7U, predetermined sound may be output according to the type of the selected character.

  In the above embodiment, in RT navigation, the stop that can be controlled by RT2 by outputting a sound according to the type of the selected one of three choices A1 to A3 and three choices B1 to B3. The player can specify the operation procedure and the stop operation procedure that can avoid the control to RT1. However, the information to be notified in the RT navigation does not directly notify the winning result of the internal lottery in this way, but avoids the procedure of the stop operation that can be controlled by the RT2 and the control to the RT1. It is only necessary to inform the player of any information that can identify the procedure of the stop operation that can be performed, and even if the information is the procedure of the stop operation itself, the winning result of the internal lottery and the stop operation are on the surface It may be irrelevant information.

  For example, in response to winning of the three choices A1 to A3, the background color of the image displayed on the liquid crystal display 4 is red (corresponding to “red 7”), white (corresponding to “white 7”), black (“ Or the character type displayed on the liquid crystal display 4 may be changed. Further, if different symbols are arranged in the vicinity of “red 7”, “white 7”, and “BAR” in the left reel 3L, such symbols may be notified. In order to avoid winning of the three choices A to C, a symbol that is not arranged in the vicinity of the symbols constituting the winning one of the three choices A1 to A3 may be notified. The same applies to the three alternatives B1 to B3.

  In the above embodiment, the symbols for which the gaming state is controlled by RT2 are the three choices A1 to A3 which are small combinations in which three medals are paid out by winning. In addition, the symbols whose gaming state is controlled by RT1 are also three-choice B1-B3 symbols, which are small roles in which three medals are paid out by winning. However, the number of medals to be paid out when winning the three choices A1 to A3 and the three choices B1 to B3 is not limited to three, but can be any number up to fifteen. However, in order to reduce the player's feeling of loss due to the fact that he / she did not win these roles, the number (one, two or three) less than three, which is the maximum bet number in one game, is set. Is preferred.

  In addition, the symbol whose gaming state is controlled by RT2 and / or the symbol whose gaming state is controlled by RT1 may be a symbol as a replay instead of a small role. For example, in addition to the replay (JAC-JAC-JAC) in the above embodiment, Replay A (red 7-JAC-JAC), Replay B (white 7-JAC-JAC), Replay C (BAR-JAC-JAC) ) As a winning combination, and this replay A to replay C may be applied instead of the above-mentioned three choices B1 to B3. Even if Replay A to Replay C are applied instead of the three choices B1 to B3, the profits that the player loses due to not winning a prize must be used for setting the number of bets for the next game. Since there are only three cards that must be played, the player's feeling of loss can be suppressed.

  In addition, when Replay A to Replay C are applied instead of the three choices B1 to B3, which are small roles, as a symbol whose gaming state is controlled by RT1, 15 games after the end of the big bonus In RT3 which is controlled only, it is good also as what does not win Replay A-Replay 3 in internal lottery. Furthermore, although the replays A to C may be won even at RT3, the winning probability may be set lower than in the normal gaming state. In this case, from the end of the big bonus until the game is consumed, the player goes to RT2 which is a gaming state without worrying (too much) that it is controlled by RT1 which is a disadvantageous gaming state. The game can be advanced while expecting the control.

  In the above embodiment, the symbols of the left reel 3L constituting the display modes of the three choices A1 to A3 are “red 7”, “white 7”, and “BAR”, respectively. The symbols on the left reel 3L constituting the display modes of the three choices B1 to B3 were also “red 7”, “white 7”, and “BAR”, respectively. Here, with respect to the left reel 3L, “red 7”, “white 7”, and “BAR” are arranged one by one, and the stop button 12L of the stop button 12L can be operated regardless of the order in which the stop buttons 12L, 12C, 12R are operated. By planning the operation timing, it was possible to win the three choices A1 to A3 and avoid the three choices B1 to B3. The operation timing of the stop buttons 12C and 12R corresponding to the middle and right reels 3C and 3R did not affect the presence or absence of the derivation of the three choices A1 to A3 and the three choices B1 to B3.

  On the other hand, depending on the arrangement of symbols on the reels 3L, 3C, and 3R, if the stop buttons 12L, 12C, and 12R are operated in a predetermined order, the RT1 must always win the role of controlling the gaming state, There are cases where operating in an order other than the order may not win a combination in which the gaming state is controlled by RT1. For example, when the three-choice B1 symbol combination is “red 7-bell-bell” and three “red 7” are arranged at intervals of 7 frames for the left reel 3L (any of reels 3L, 3C, 3R). Assuming that the “bells” are arranged at intervals of 5 frames or less), when the 3rd choice B1 is won, if the left reel 3L is operated first, the 3rd choice B1 will always be won, but the left If the reel 3L is not operated first, there is a case where the three-choice B1 is not won depending on the operation timing.

  Similarly, if the symbol combination of 3 options B2 is “Bell-White 7-Bell” and three “White 7” are arranged at an interval of 7 frames for the inner reel 3C, is it sure to win 3 Options B2? No is determined by the order in which the inner reel 3C is operated. If the symbol combination of the 3 choice B3 is “Bell-Bell-BAR” and three “BARs” are arranged at intervals of 7 frames on the right reel 3R, whether or not to win the 3 choice B3 is determined by the right The order in which the reels 3R are operated is determined.

  In this case, in the RT navigation, when the three choices B1 to B3 are won, only the operation order of the stop buttons 12L, 12C, and 12R that always wins the three choices B1 to B3 may be notified. However, even if the type of the winning one of the three choices B1 to B3 is notified, the player specifies the operation order of the stop buttons 12L, 12C, and 12R that always wins the three choices B1 to B3 depending on the type. be able to. The same applies to the three alternatives A1 to A3 that allow the RT2 to control the gaming state.

  Thereby, according to the notified operation order (or the operation order specified according to the notified type of combination), the player can select the stop buttons 12L, 12C, By operating 12R, the gaming state can be controlled by RT2. Further, if the stop button 12L, 12C, 12R is operated in an order other than the order of reliably winning at least the three choices B1 to B3, and the stop button 12L is operated at a timing at which the three choices B1 to B3 are not won, the control to RT1 is performed. Can be avoided.

  In the above embodiment, when it is determined that RT navigation is to be performed except when the number of digested games after the bonus ends becomes 700 games or more, the RT navigation is controlled to RT1 or RT2 next. (However, until the regular bonus or big bonus is controlled) Once the gaming state is controlled by RT1 or RT2, it is determined that RT navigation will not be performed again. It was never done. In addition, RT navigation would not be terminated no matter how many games were consumed unless the gaming state was controlled by RT1 or RT2 without winning the three choices A1 to A3 and the three choices B1 to B3.

  On the other hand, if it is determined that RT navigation is to be performed before the number of digested games after the bonus ends reaches 700 games, the determination of performing RT navigation in the big bonus RT navigation may be performed until the predetermined number of games is exhausted. Alternatively, RT navigation may be performed until a predetermined time elapses after it is determined that RT navigation is performed (in the determination that RT navigation during a big bonus is performed after the end of the big bonus).

  In the above embodiment, in the game from the end of the bonus to the start of the next bonus, RT navigation is not performed unless the number of digested games after the bonus becomes 700 or more. On the other hand, RT navigation lottery is performed only when the gaming state is controlled by RT1 or RT2, and RT navigation can be performed even in a normal gaming state after RT1 or RT2 is ended by winning this. It may be a thing.

  In this case, in the RT navigation lottery performed when the gaming state is controlled to RT2, the winning probability is low if any part is won, but when all the parts are lost It is possible to win with higher probability than when winning some role. In this case, even if the RT2 game fails to win any role, the expectation of winning the RT navigation lottery increases, thereby preventing the player's expectation from being reduced.

  On the other hand, in RT navigation lottery performed when controlled by RT1, there is a high probability that all combinations will be lost in RT1 in RT1, so a game that lost all combinations in internal lottery as in RT2 However, instead of increasing the winning probability of the RT navigation lottery, for example, the winning probability of the RT navigation lottery may be increased in a game that wins (or wins) a specific role such as a watermelon. Thereby, when winning a specific combination in RT1, it is possible to give the player a sense of expectation that RT navigation will be performed, and to further improve the interest of the game.

  In the above embodiment, the value of the inter-bonus game counter is cleared to 0 when winning either the regular bonus or the big bonus, and if this value is 700 or more and the normal gaming state is achieved. RT navigation was supposed to be executed. Of course, in regular bonuses (not including those offered during the big bonus), RT Navi lottery is not performed, so the number of games where RT Navi is not executed may become too large in regular bonus winnings. . Therefore, while the game state is controlled by the regular bonus, the value of the game counter between bonuses is not added, but the value of the game counter between bonuses may not be cleared when the regular bonus is won. Thereby, it can prevent that the period when RT navigation is not performed becomes too long.

  In the above embodiment, before the first game of the big bonus is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the timing when the bet number for the first game of the big bonus is determined. In accordance with the type of character displayed in, the type of effect in the big bonus is selected. However, the type of performance during the big bonus is not selected by the operation related to the progress of the game like the setting of the number of bets, but the player can be selected by an operation completely independent of the progress of the game. Also good. Also, the RT navigation notification may be the only effect whose contents are changed in the big bonus according to the player's selection.

  In the above embodiment, whether or not to perform RT navigation at a different opportunity is determined according to the type of character selected by the player at the start of the big bonus. When it is determined that RT navigation is to be performed, RT navigation notification is performed in a different manner depending on the type of character selected by the player at the start of the big bonus, and at a different timing. On the other hand, only the RT navigation notification mode differs according to the type of character selected by the player, or only the timing for performing the RT navigation notification depends on the character type selected by the player. You can also.

  In the above embodiment, only the big bonus of the regular bonus and the big bonus is selected by the player's operation by selecting the type of character (effect mode) executed during the big bonus at the start of the bonus. Whether or not to perform RT navigation is determined in accordance with the type of RT navigation, and RT navigation notification is performed. However, these things can be performed not only in the big bonus but also in the regular bonus, and can be performed only in the regular bonus without being performed in the big bonus.

  In the above embodiment, the operation means for the player to instruct execution of the history display effect is also used as the effect stage switching button 17 for instructing to switch the effect stage, but is separate from the effect stage switching button 17. Operation means may be provided. In addition, the production stages that are switched by operating the production stage switching button 17 are not limited to the two types of stages 1 and 2, and there may be three or more types of stages. In this case, effect data such as a bonus medium effect may be prepared for each type of effect stage and stored in the ROM 123 in advance.

  Further, the difference in the production stage is not limited to the type of character appearing in the production and the type of background image used in the production. Only one of the type of character appearing in the production and the type of background used in the production may be different depending on the production stage. For example, only the character appearing in the production and / or the background color used for the production may be different depending on the production stage. Moreover, the difference in effect stage can also cause a difference in the execution probability of the effect and the execution mode of the effect. For example, the execution probability of the winning notification effect may be different depending on whether stage 1 or stage 2 is selected.

  Furthermore, the images displayed on the liquid crystal display 4 may be exactly the same even if the performance stages are different. In addition to displaying images on the liquid crystal display 4, the effects in the slot machine are not only the display of images but also the sound output from the speakers 7L, 7R, 7U, the reel lamp 3LP and the game effect lamp. Many of them are performed by combining lighting of 75A to 75M. Therefore, for example, the images displayed on the liquid crystal display 4 in the stage 1 and the stage 2 are the same, but the BGM (Back Ground Music) of the effect may be different.

  In the above embodiment, only one CPU 121 is mounted on the effect control board 102, and the CPU 121 reads the effect data from the ROM 123 and stores the effect data to the execution effect data area 122-3 in the RAM 122. The writing, the development of the image data in the frame buffer 122-4, and the display on the liquid crystal display 4 of the image corresponding to the image data developed in the frame buffer 122-4 are all controlled. On the other hand, a video processor that controls display of an image on the liquid crystal display 4 may be provided separately from the CPU 121. Here, the video processor may have its own memory (VRAM) separately from the RAM 122.

  When the video processor has its own VRAM, only the frame buffer can be provided in the VRAM, or both the execution effect data area and the frame buffer can be provided in the VRAM. In the former case, the CPU 121 performs reading data from the ROM 123 to the execution effect data area 122-3 and sends a command to the video processor. The video processor transmits the effect data from the execution effect data area 122-3. And the image data can be developed in a frame buffer in the VRAM.

  In the latter case, the CPU 121 may read the effect data from the ROM 123 and pass it to the video processor, and the video processor may write the effect data passed to the execution effect data area in the VRAM. The image data may be developed in a frame buffer in the VRAM based on the effect data written in the execution effect data area in the VRAM.

  On the other hand, if the video processor does not have its own VRAM, both the CPU 121 and the video processor may write data to the RAM 122. In this case, the CPU 121 controls from the reading of the effect data to the ROM 123 to the writing to the execution effect data area 122-3 to the frame buffer 122-4 based on the effect data written in the execution effect data area 122-3. The video processor can control the development of the image data and the display of the image on the liquid crystal display 4.

  Note that the CPU 121 and the video processor control the reading of the effect data from the ROM 123 and the writing of the effect data to the execution effect data area 122-3 (or the execution effect data area in the VRAM) for each word. You don't have to. For example, the first address and the last address (or data size) of the effect data to be read from the ROM 123 are specified, and the data in the specified range is collected in the execution effect data area 122-3 (or the execution effect data area in the VRAM). Even when the data is transferred and written, the CPU 121 or the video processor controls the reading of the effect data from the ROM 123 and the writing of the effect data in the execution effect data area 122-3 (or the execution effect data area in the VRAM). Will be.

  In the above embodiment, the demonstration effect has been started because the game has not progressed for a predetermined time in a period other than during the game, but this demonstration effect effect data is the first time the execution effect data area of the RAM 122 It was supposed to be written in 122-3. On the other hand, when one game is over (for example, triggered by reception of a winning information command or a gaming state command), demonstration effect effect data may be written in the execution effect data area 122-3. However, the demonstration effect data is not written in the bonus even if one game ends. In this case, when it is determined that the game has not progressed for a predetermined time in a period other than during the game, the demonstration effect is executed using the effect data written in the execution effect data area 122-3 at the end of the game. What should I do?

  Further, in a period other than during the game in which the display result of the variable display device 2 is derived from the operation of the start lever 11, even after the bet number is set for the next game, the start lever 11 is not operated after that for a predetermined time. However, the demonstration effect may not be executed even if a predetermined time elapses without the start lever 11 being operated after the betting number is set. In this case, regardless of whether or not the effect is during the bonus, the demonstration invalid flag is set in response to the reception of the BET command transmitted from the game control board 101 to the effect control board 102 when the bet number is set. It is only necessary to disable the operation of the switching button 17.

  In the embodiment described above, even during a period other than during the game from the operation of the start lever 11 to the derivation of the display result on the variable display device 2, the period from the bonus winning until the bonus ends, or the RT2 In the period from when the remaining number of games becomes 3 games or less until RT2 ends, the demonstration invalidation flag is set and the demonstration stage, Switching between the history display effect and the effect stage is prohibited.

  On the other hand, the stage is rewritten by a program executed during the period from the bonus winning until the bonus is ended, or the period until the RT2 is ended after the RT2 remaining number of games is 3 games or less. It is also possible to prohibit the switching of the production stage by not calling the module. Furthermore, when the demonstration effect and history display effect production data is written by a module different from the bonus production data, the period from the bonus winning until the bonus ends or the number of remaining games in RT2 The demonstration program and the history display effect are executed without calling the module that writes the demonstration data of the demonstration effect and the history display effect in the program that is executed during the period from when the game becomes 3 games or less until the end of RT2. It can also be prohibited.

  In the above embodiment, display on the variable display device 2 except for the period from the bonus winning until the bonus is ended and the period until the RT2 is ended after the remaining number of games in RT2 is three games or less. In the period between the game from the derivation of the result to the operation of the start lever 11, the stage can be switched between the stage 1 and the stage 2 by simply operating the stage switching button 17 for a short time. On the other hand, the stage switching procedure is not realized by a single operation in this way, but first, the stage switching screen for performing stage switching by the first stage operation is displayed on the liquid crystal display. The stage may be switched by performing the second stage operation according to the displayed stage switching screen displayed on the device 4.

  In this case, the ROM 123 further stores effect data for causing the liquid crystal display 4 to display an effect stage switching screen (a type of effect). Further, for example, assuming that three types of stage stages 1 to 3 are prepared, the stage 123 and the stage 2 have the same configuration as stage 1 and stage 2, and the stage 123 winning stage presentation data and various bonus stage data are stored in the ROM 123. Will be stored.

  When the effect stage switching button 17 is operated for a short period of time between the game from the derivation of the display result on the variable display device 2 to the operation of the start lever 11, the ROM 123 displays the effect stage switching screen. It is assumed that the effect data is read and written in the execution effect data area 122-3 of the RAM 122. By operating any of the stop buttons 12L, 12C, 12R according to the effect stage switching screen displayed on the liquid crystal display 4 according to the effect data of the effect stage switching screen written in the execution effect data area 122-3, the stage Any stage of stage 1 to stage 3 can be selected.

  Even when the stage is selected as described above, the demo invalid flag is set in the period from the bonus winning until the bonus is ended and the period from the remaining number of RT2 games of 3 or less until RT2 ends. Since the operation of the effect stage switching button 17 is invalidated, the effect data on the effect stage switching screen is not read from the ROM 123 and written into the execution effect data area 122-3. The effect stage switching screen is not displayed on the liquid crystal display 4 because the effect stage switching screen is not written in the execution effect data area 122-3, and therefore the operation of the effect stage is performed by operating the stop buttons 12L, 12C, and 12R. It cannot be switched.

  Thus, since the reading of the effect data of the effect stage switching screen from the ROM 123 and the writing to the execution effect data area 122-3 are prohibited, the bonus effect being executed is being executed during the execution of the bonus effect or the continuous effect. The data is not overwritten by the effect data on the effect stage switching screen and is not erased from the execution effect data area 122-3. Since it is not erased, it is not necessary to read out bonus effect data from the ROM 123 and write it into the execution effect data area 122-3.

  For this reason, in order to display an effect stage switching screen that is not directly related to the current game progress, bonus effect data and continuous effect data with a large amount of data are read from the ROM 123 and the execution effect data area 122 of the RAM 122 is read. The overhead of the process of writing to -3 is not duplicated. Further, if the effect stage switching screen is not displayed, it is impossible to switch the effect stage. Therefore, the effect data corresponding to the same situation is read from the ROM 123 and only written in the execution effect data area 122-3 of the RAM 122. It is possible to prevent the overhead of not becoming necessary. In addition, there is no processing overhead of saving data indicating how much of the effect during the bonus has been executed when displaying the effect stage switching screen, and returning the data after the effect stage has been switched.

  It should be noted that the modification described here can also be applied to the case where the types of effects that can be executed are set by the same two-stage operation as described above, even if there is no demarcation stage. For example, this modification is also possible when an effect type setting screen is displayed on the liquid crystal display 4 by the first operation and an effect type that can be executed according to the effect type setting screen displayed on the liquid crystal display 4 is set. It is possible to apply the method shown in the example. Moreover, in the modification demonstrated here, even if it is a case where there is no difference in the image displayed on the liquid crystal display 4 according to the difference in production stage, there exists an effect of this invention.

  In the above embodiment, the continuous effect is executed until the RT2 ends after the RT2 remaining number of games becomes three. Here, the pattern of the continuous performance depends on whether the regular bonus, the big bonus (1) or the big bonus (2) is won at the end of the game in which the remaining number of games in RT2 is 3 from the next game. The continuous effect data of the selected pattern is written in the execution effect data area 122-3.

  However, the regular bonus, big bonus (1), or big bonus (2) is not won from the next game until the game where the remaining number of RT2 games is three, but by the time RT2 ends, You may win a regular bonus, a big bonus (1) or a big bonus (2). In this case, if the continuous production is simply ended by the end of RT2, the content of the executed continuous production is the winning status of the regular bonus, the big bonus (1) or the big bonus (2) at the end of RT2. May become different.

  Therefore, it is determined whether the regular bonus, the big bonus (1) or the big bonus (2) is won again in the game in which the RT2 is finished and the continuous production is finished. You may decide to continue performing an additional production. In this case, the effect data of the additional effect is also stored in advance in the ROM 123 according to the effect stage, and when it is decided to perform the additional effect, the effect data of the additional effect is written in the execution effect data area 122-3. It is good also as what performs an additional effect in this game. When the additional effect is executed, the demonstration prohibition flag is not erased even when RT2 is finished, and the demonstration prohibition flag may be erased after the additional effect is also finished.

  Alternatively, it is determined whether the regular bonus, the big bonus (1) or the big bonus (2) is won at the start of the game at which the RT2 is finished. May be. In this case, the effect data of the replacement effect is stored in advance in the ROM 123 according to the effect stage, and when it is decided to replace the content of the effect, the effect data of the replacement effect is stored in the execution effect data area 122-3. What is necessary is just to perform writing and replacement production.

  When a regular bonus, a big bonus (1) or a big bonus (2) is newly won after the continuous production is started in this way, the regular bonus can be obtained by executing an additional production or replacing the content of the production. The situation that is different from the winning situation of the big bonus (1) or the big bonus (2) does not remain informed to the player, and the player can be prevented from feeling distrust.

  In addition, when it is assumed that an additional effect can be executed after the continuous effect, the content of the effect executed in the continuous effect is not won for the regular bonus, the big bonus (1) and the big bonus (2). Even if it is shown, the player's interest in winning the regular bonus, the big bonus (1) or the big bonus (2) is not reduced. Thereby, the interest of a game can be improved.

  In the above embodiment, the continuous effect is executed until the RT2 ends after the RT2 remaining number of games becomes three. However, when the chance result is derived as the display result of the variable display device 2, It is good also as what performs a continuous production only for a predetermined number of games (for example, 3 games) from there. If the chance is derived, it means that there is a possibility that the regular bonus, the big bonus (1), or the big bonus (2) is won. By performing the continuous production over the period of, you can continuously give the player a sense of expectation for winning the regular bonus, big bonus (1) or big bonus (2), further improving the interest of the game Can be made.

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

  In the above embodiment, the number of determination values for the lottery target determined according to the gaming state is sequentially added to the random number for internal lottery, and is read as the lottery target at the time when an overflow occurs as a result of the addition. He was supposed to win the role that had been put out. On the other hand, the number of determination values may be sequentially subtracted from the internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative). In addition, according to the number of determination values of each combination according to the gaming state, a winning determination table that determines a determination value for determining each combination as winning is created for each game, and the acquired random number for internal lottery is set. It is good also as what performs an internal lottery by comparing with the determination value of each combination.

  In the above embodiment, in any gaming state, the game can be started only by setting 3 as the bet number. However, the number of bets that can be set to start the game can be any number in the range of 1 to 3. The number of bets that can be set for each gaming state may be different. Here, when 1 or 2 is set as the bet number in the normal gaming state or RT, the winning probability of the small part in the internal lottery is lowered and the small part is reduced as compared with the case where 3 is set as the bet number. It is possible to increase the number of medals to be paid out when winning.

  In the above embodiment, in a game in which the gaming state is the big bonus and the big bonus medium flag is set in the RAM 112, it is determined whether or not the regular bonus medium flag is set in the RAM 112 when the start lever 11 is operated. If the regular bonus medium flag is not set, this is set to control the regular bonus. Thus, even when the regular bonus is controlled first after the big bonus (1) or big bonus (2) is won, the regular bonus is controlled again when the regular bonus for one time has ended and the big bonus has not yet ended. Even in this case, the same processing should be performed.

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

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

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

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn.

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

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

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