Description

  The present invention relates to a slot machine, and more particularly to control of execution of effects.

  The slot machine generally includes a variable display device having a plurality of reels having a plurality of types of symbols drawn on the outer peripheral portion, and pays out medals as a valuable value according to a display mode when rotation of each reel is stopped. Is. Further, according to the display mode when the rotation of the reel is stopped, it is possible to shift to a gaming state advantageous to the player.

  In other words, the profit and loss in the progress of the game can be said to be determined by the display mode appearing on the variable display device, but the display mode (hereinafter referred to as a winning mode) that involves paying out medals and shifting to an advantageous gaming state is usually used. Is only allowed if a prior internal lottery is won. In addition, the internal lottery is performed for each of a plurality of types of winning modes, but the advantageous game progression method differs depending on which mode is selected.

  Therefore, conventionally, the player is notified of the result of the internal lottery by the effects of light, sound, images, and the like. Such effects are generally performed for each game, but a slot machine is also proposed in which effects are performed over a plurality of games (see, for example, Patent Document 1). In recent years, there is a tendency for the contents of the effects in the slot machine to become more complex, such as effects over a plurality of games.

  For this reason, in recent slot machines, a control circuit (effect control means) for controlling an effect device (lamps, speakers, liquid crystal display, etc.) for effecting light, sound, images, etc. Some are configured separately from the control circuit (game control means) for controlling the progress.

JP 2001-58025 A

      However, in the conventional slot machine, the effect control means only controls the effect device, and it is determined on the side of the game control means whether or not the effect is to be performed. It was. In recent years, not only the contents of the effects have become complicated, but the types of effects have also tended to increase. Therefore, there is a problem that the processing load on the game control means increases in the process of determining such effects. It was.

  In addition, in the slot machine described in Patent Document 1, it is assumed that an effect over a plurality of games is executed. If this effect is determined to be executed in any game, an effect of a predetermined pattern is provided. However, the game was only performed in stages. In this case, the production period was no different from that of a longer production period, and lacked novelty as a production variation. For this reason, in the effect as in the slot machine described in Patent Document 1, the interest of the game cannot be sufficiently improved.

  An object of the present invention is to provide a slot machine that reduces the load on the game control means by determining the execution of the performance independently of the control of the progress of the game.

  Another object of the present invention is to provide a slot machine that improves the fun of games by performing novel effects.

In order to achieve the above object, the slot machine of the present invention provides:
By setting the number of bets for one game, it is possible to start the game. When the display result of the variable display device is derived and displayed, one game is completed, and according to the display result of the variable display device. In a slot machine where a predetermined winning can occur,
Pre-determining means for pre-determining whether to allow the occurrence of the prize;
Game control means for controlling the progress of the game and transmitting a pre-determining command indicating the determination result of the pre-determining means in each game,
A gaming state transition means for transitioning the gaming state to a special gaming state advantageous to the player by the occurrence of a predetermined special prize;
Receiving a pre-determined command transmitted from the game control means, and producing an effect indicating information on whether or not the pre-determining means allows the occurrence of the special prize based on the received command Production control means to be executed,
The effects that the effect control means causes the effect means to execute include one game effect that is executed within a period of one game and a plurality of game effects that are continuously executed over a period of a plurality of games,
The multi-game effect includes an initial stage effect executed in the first game of the multi-game effect, an intermediate stage effect executed in the game after the initial stage effect is executed, Information indicating whether or not the pre-determining means allows the occurrence of the special prize by the multi-game effect, including the final stage effect executed after the game in which the effect is executed In addition, the final stage production may end without being executed,
The production control means includes
Production stage storage means for storing information indicating whether the production of the stage of the initial stage and the production of the stage in the middle stage has been executed,
When the multi-game effect is not executed, the one-game effect is executed, the multi-game effect is executed, or the one-game effect and the multiple-game effect are both executed based on the predetermined command. Means for determining whether or not to execute the game, and when the predetermined command received from the game control means indicates that the special winning is permitted, the special winning is permitted. Effect determining means for determining to execute the plurality of game effects at a higher probability than when not indicating the effect;
The one-game effect is executed by the effect means according to the decision to execute the one-game effect by the effect determining means, and the effect of the multiple-game effect is determined according to the decision to execute the multiple-game effect by the effect determining means. Effect execution means for causing the effect means to sequentially execute the effects of the initial stage, the middle stage and the final stage according to the information stored in the stage storage means,
The production execution means
When the effect determining means determines that the multi-game effect is to be executed, the initial stage effect of the multi-game effect is executed and the initial stage effect is executed by executing the initial stage effect. Information indicating the effect is stored in the effect stage storage means to shift to a state in which effects after the mid-stage of the multiple game effects can be executed,
Wherein the plurality game initial stage of the effect, after the end effect of the middle stage, respectively, by waiting a step of directing at idle running state of the effect until it receives a command to switch to the next phase of the game, game And continuously executing the multi-game effects even between the games,
When the pre-determined command received from the game control means indicates that the special winning is not permitted, the plurality of games can be performed up to the mid-stage stage without executing the final stage stage. End the production,
The final stage effect may be executed after the mid-stage effect is completed on condition that the pre-determined command received from the game control means indicates that the special winning is permitted. It is possible to notify that the advance determination means allows the occurrence of the special prize by executing the final stage of the multi-game effects.

In the slot machine, the production control means determines not only the production execution control but also the production execution. For this reason, the processing load concerning a game control means can be made small. In addition, there are many variations of the effects that the effect control means causes the effect means to execute, which are one-game effects and multiple-game effects. For this reason, the interest of a game can be improved. Further, the effect determining means can receive a pre-determined command corresponding to each game, so that when the multi-game effect is not executed, the effect to be executed is determined according to the pre-determined result of each game. can do.

In the above slot machine,
The game control means preferably performs a predetermined transmission delay process when transmitting the prior determination command to the effect control means.

  The predetermination by the predetermination means is normally made when the player performs a game start operation, but at this timing, the variable display of the identification information on the variable display device is also started. By performing the transmission delay process for the pre-determined command, a timing shift occurs between the effect executed on the effect control board side and the variation display of the identification information. Therefore, the timing of the variable stop operation by the player due to the effect is determined. It can be prevented.

In the above slot machine,
The production control means further includes a unique random number generation means independent of the prior determination means and the game control means ,
The effect determining means determines execution of the one game effect and execution of the multiple game effects according to a random number value generated by the random number generating means and a pre-determined command received from the game control means. Can do.

  In this case, since the effect control means can independently generate random numbers for determining the effect, the processing load is not applied to the game control means.

In the above slot machine,
The one-game effect can be completed within one game period and the final result of the effect can be shown.

  With one game effect having such contents, the result of the effect (for example, information related to the determination result of the predetermining means) can be easily shown to the player.

In the above slot machine,
The multi-game production has a plurality of stages divided corresponding to each game, and the mid-stage and final stage productions show the continuation of the initial and mid-stage productions, respectively. It may be a thing. In the case of such a plurality of stages, an effect that shows each stage as a series of series is configured.

By showing the effects of each stage of the multiple game effects as a series of games, it is possible to improve the interest of the game.

Here, the said effect determination means shall determine for every game whether the effect of each step of the said multiple game effect is performed.

In this case, the effect determining means determines in each game whether to continue the multi-game effect or to cancel the multi-game effect halfway. In other words, since the multi-game effect may be executed to the end or may be stopped halfway, the variation of the effect increases and the interest of the game can be improved.

Is forming.

  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 executed based on a command received from the game control board 101 via the buffer circuit 127 and the I / O port 124. In particular, the notice effect or the notice effect is performed based on the winning status notification command and the acquired random number with reference to the notice effect determination table or the notice effect determination table.

  The RAM 122 is used as a work area when the CPU 121 executes a program, for example, for temporarily storing a winning status notification command to be described later. The ROM 123 stores fixed data including a program executed by the CPU 121, a notification effect determination table, and a notice effect determination table. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

The switch signal, medal IN signal, and medal OUT signal are output to the external device.

  Next, the internal lottery will be described. The internal lottery is to determine in advance whether or not winnings to each combination, which will be described later, is permitted. The random number acquired using the hardware random number function, the setting by the setting switch 91, the bet number set by the player, Then, referring to a winning determination table prepared in the ROM 113 based on the current gaming state, the CPU 111 performs such a means for pre-determination. When the internal lottery is won, a winning flag corresponding to the winning combination is set in the RAM 112 of the game control board 101. The winning flag is stored, for example, in one word (16 bits) in which the type of combination is determined for each bit.

  In addition, depending on the result of the above internal lottery, a big bonus winning flag, a regular bonus winning flag, a small role winning flag (multiple depending on the type of small role), a replay winning flag, and a JACIN winning flag (replay) in the big bonus In the regular bonus, a JAC winning flag (a flag set in substantially the same position as the replay flag) is set in the RAM 112 in the game control board 101. Only one winning flag is newly set in one game, but only the big bonus winning flag and the regular bonus winning flag are carried over from the next game until the actual winning.

  Based on the information related to various winning flags set in the RAM 112 based on the result of the internal lottery, a winning status notification command with a predetermined header is generated by the CPU 111, and an effect is produced from the game control board 101 for each game. It is sent to the control board 102. However, the content of the winning status notification command is converted and transmitted to the effect control board 102 in a predetermined case so that the result of the internal lottery is not completely output to the outside. The conversion of the contents of the winning status notification command will be described in detail later.

  When the various winning flags described above are set in the RAM 112, it is possible to generate a corresponding role or a JACIN in a big bonus. That is, when the reels 3L, 3C, and 3R are stopped, a winning symbol can be won on the active line set according to the number of bets of the variable display device 2. At the time of winning a prize, medals are paid out, and the gaming state is changed with the winning. There are three game states to be controlled on the game control board 101 side: a normal game state, a big bonus, and a regular bonus. Hereinafter, the “combination” determined as the winning will be described.

  For example, when three “BARs” are arranged on the active line corresponding to the number of bets, the gaming state shifts to a regular bonus. A regular bonus is obtained by playing a game called a regular bonus game a predetermined number of times (for example, 12 times) or by winning a predetermined number of times (for example, 8 times) ("JAC" is aligned on the active line). finish. The game control board 101 is provided with a counter for counting the number of regular bonus games and the number of winnings thereof. It should be noted that the state that has shifted to the regular bonus, that is, the gaming state in which the regular bonus game is provided is called a first special gaming state, and a regular bonus flag is set in the RAM 112 in the gaming control board 101.

  For example, when three “colored 7” or three “colorless 7” are arranged on the active line corresponding to the bet number, the gaming state shifts to a big bonus. In the big bonus, up to 30 games called small role games can be played. In this small role game, “JAC” is arranged on the active line with a relatively high probability (JACIN), and when the JACIN is performed, the regular bonus described above is provided (up to 3 times).

  The big bonus ends when 30 small-games end or when a regular bonus based on the third JACIN ends. The game control board 101 is provided with a counter for counting the number of small role games, the number of JACIN, the number of regular bonus games and the number of winnings thereof, and the number of medals acquired in the big bonus. Note that the state shifted to the big bonus is referred to as a second special game state, and a big bonus medium flag is set in the RAM 112 in the game control board 101.

  In addition, when a “watermelon”, “cherry”, or “bell” is arranged in a game other than a regular bonus game (including a case where the bonus is provided during the big bonus), a small role winning is awarded. These small roles will not be won in the internal lottery. When the “watermelons” are arranged among the small roles, the winning probability of the small role is the lowest, which is 1/30. The winning probability of other small roles is 1/10.

  Further, except for the small role game and the regular bonus game that are provided during the big bonus period, when “JAC” is arranged on the active line, a replay prize is awarded. The winning probability of “Replay” is 1/7.

  Note that the big bonus winning flag and the regular bonus winning flag are not set during the big bonus or the regular bonus. Further, during the regular bonus (including the case of JACIN during the big bonus), the small role winning flag (not including the JAC winning flag) is not set.

  When there is a winning combination as described above, the number of medals corresponding to each winning combination is paid out (except for the case where the winning combination is 50 until the number of credits reaches 50). A corresponding number of credits are accumulated as data, and in this case as well, medals are paid out as valuable value). In addition, the number of medals to be paid out is 15 except for 8 small roles by “Watermelon” and 4 small roles by “Cherry”.

  Next, conversion of the contents of the winning status notification command will be described. The winning status notification command is converted according to the status of various winning flags and the obtained random number value with reference to the winning status notification command conversion table provided in the ROM 113 of the game control board 101. FIG. 7 is a diagram showing a winning status notification command conversion table provided in the ROM 113.

  As a random number for converting the winning status notification command according to the winning status notification command conversion table, the CPU 111 acquires two random numbers for conversion of the winning status notification command (hereinafter referred to as first and second random numbers). The random number here is performed using a software random number function different from the hardware random number function described above. This software random number function is generated by a timer interrupt generated in the CPU 111, and is provided with a random number register for updating the random number for each application. The range of random numbers is determined for each application.

  More specifically, the CPU 111 generates a timer interrupt, for example, at a cycle of 1.9 milliseconds. Each time this timer interrupt occurs, the value of each random number register is incremented by 1 and updated. When the upper limit value of the random number range is reached, the next update is made to the lower limit value. When performing processing for acquiring any random number using the software random number function, the CPU 111 generates a random number by acquiring a random number stored in the random number register at that time. It is supposed to be.

  Moreover, the range of the value of the first random number is, for example, 1 to 223, and can take 223 values. The range of the value of the second random number is 1 to 227, and can take 227 values. With these first and second random numbers, the CPU 111 can obtain 223 × 227 = 50621 random numbers in total. Here, since the number of values that can be taken by the first and second random numbers is a prime number, both are prime numbers, it is set to such a condition. Other numbers may be used as long as they are satisfied.

  Here, the first and second random numbers are provided, and the prime numbers close to 256 of the maximum values that can be acquired using the software random number function are applied to convert the winning status notification command. Therefore, the random number value obtained using the software random number function has a long period of synchronization with the random number value obtained using the software random number function for other purposes (there is no relation to the present invention and is omitted). And to increase the range of random numbers.

  In the normal gaming state, when the random number value thus obtained is any one of A, B, C, D, and E, a process for converting the winning status notification command is performed (however, A, B, C, D and E are specific numbers determined in advance). In the case of a big bonus (only in the small role game), if the acquired random number value is E, processing for converting the winning status notification command is performed, and the acquired random number values are A, B , C, and D, the process for converting the winning status notification command is not performed. When a regular bonus (including a regular bonus in a big bonus) is performed, processing for converting the winning status notification command is not performed, and it is specified with a 100% probability in the effect control board 102 that all roles have been lost. In order not to be able to do so, a winning status notification command indicating that all the combinations are lost is always transmitted to the effect control board 102.

  That is, referring to the winning status notification command conversion table of FIG. 7, when winning a big bonus or a regular bonus (which can only be a normal gaming state), the contents of the winning status notification command are converted. There is no. Although not shown in the figure, when the gaming state is a regular bonus, it is converted into a winning status notification command indicating that all the combinations are lost.

  In the winning status notification command that indicates that you are losing to the big bonus and regular bonus (they can only be such a thing during the big bonus), according to the value of the winning status of the small role and the acquired random number as follows The winning status notification command is converted. If all small roles are lost, the contents of the winning status notification command are not converted.

  If the value of the random number is A in the normal gaming state, a command indicating that the big bonus and watermelon are won when the watermelon is won, and a command indicating that the big bonus and bell are won when the bell is won In addition, when winning a cherry, it is converted into a command indicating that the big bonus and cherry are won, and when winning a replay, they are converted into a command indicating that the big bonus and replay are won.

  If the value of the random number is B in the normal gaming state, a command indicating that the regular bonus and the watermelon are won when the watermelon is won, and a command indicating that the regular bonus and the bell are won when the bell is won In addition, the regular bonus and the command indicating that the cherry is won when the cherry is won are converted into the command that indicates that the regular bonus and the replay are selected when the replay is selected.

  If the value of the random number is C in a normal gaming state, the command that indicates that the big bonus is won when the watermelon is won, the command that indicates that the bell is won when the bell is won, Sometimes it is converted into a command indicating that the cherry is won, and when the replay is won, it is converted into a command indicating that the replay is won. Here, for example, converting to a command indicating that the bell is won at the time of winning the bell means that the content of the winning status notification command does not change before and after the conversion process, but the conversion process itself is performed. I mean.

  If the value of the random number is D in the normal gaming state, the command that indicates that the regular bonus is won when the watermelon is won, the command that indicates that the bell is won when the bell is won, Sometimes it is converted into a command indicating that the cherry is won, and when the replay is won, it is converted into a command indicating that the replay is won.

  If the value of the random number is E in the normal gaming state or big bonus, the command that indicates that the watermelon is won when the watermelon is won, the command that indicates that the bell is won when the bell is won, It is converted into a command indicating that it is lost in all roles when winning, and a command indicating that winning in replay when winning a replay.

  FIG. 8 is a diagram showing the probability that the winning status conversion command is converted into another content according to the above winning status notification command conversion table. FIG. 8A shows the probability in the normal gaming state. Indicates a big bonus. The value of the denominator in each column of this table is 50621, the same as the type of random number that can be acquired.

  As shown in FIG. 8 (a), in the normal gaming state, is the winning status notification command generated based on the result of the internal lottery (without conversion processing) lost as a bonus? , Whether the big bonus is won or the regular bonus is won. In addition, as a small role, it indicates whether it is lost for all small roles, winning a watermelon small role, winning a bell small role, winning a cherry small role, or replay winning.

  Since the Big Bonus Winning Flag and Regular Bonus Winning Flag can be carried over, it becomes a winning status notification command indicating that either the big bonus or small role is won, and that either the regular bonus or small role is won. Sometimes. The winning status notification command indicating that you have won the big bonus or regular bonus will not be converted into other status winning status notification commands, regardless of the winning status of the small role Absent. In the winning status notification command indicating that the bonus has been lost, the winning status notification command indicating that all of the small roles have been lost is not converted into the winning status notification command having other contents.

  In addition, the winning status notification command indicating that the bonus has been lost and the winning of the watermelon small role is won with a probability of 1/50621 according to the random number obtained as described above. And, it is converted into a winning status notification command indicating that all the small roles are lost. It is converted into a winning status notification command indicating that a big bonus is won with a probability of 1/50621 and a watermelon small role is won. Furthermore, it is converted into a winning status notification command indicating that the regular bonus is won with a probability of 1/50621 and that all small roles are lost. It is converted into a winning status notification command indicating that a regular bonus is won with a probability of 1/50621 and a watermelon small role is won. The remaining 50617/50621 probabilities are not converted into winning status notification commands of other contents.

  The winning status notification command indicating that the bonus is lost and the winning of the small part of the bell is won with a probability of 1/50621 according to the random number acquired as described above, and It is converted into a winning status notification command indicating that the small part of the bell has been won. It is converted into a winning status notification command indicating that the regular bonus is won with a probability of 1/50621 and that the small part of the bell is won. The remaining 50619/50621 probabilities are not converted into winning status notification commands of other contents.

  The winning status notification command indicating that the bonus has been lost and the winning of the cherry small part is won according to the random number obtained as described above, with a probability of 1/50621, and It is converted into a winning status notification command indicating that the small role of cherry is won. It is converted into a winning status notification command indicating that a regular bonus is won with a probability of 1/50621 and that a cherry small role is won. It is converted into a winning status notification command indicating that all bonuses and small roles are lost with a probability of 1/50621. The remaining 50618/50621 probabilities are not converted into winning status notification commands of other contents.

  The winning status notification command indicating that the bonus is lost and the replay winning is won with the probability of 1/50621 according to the random number obtained as described above, and the replay is won. It is converted into a winning status notification command indicating this. It is converted into a winning status notification command indicating that the regular bonus has been won and the replay has been won with a probability of 1/50621. The remaining 50619/50621 probabilities are not converted into winning status notification commands of other contents.

  Here, there is a high probability that the winning status notification command indicating the winning of a watermelon small role will be converted into a winning status notification command of other contents. This is because the winning probability of the watermelon small role is lower than the winning probability of the other small roles, and the probability that the winning status notification command having the content different from the state of the winning flag set originally is transmitted to the effect control board 102. This is because it can be lowered as a whole. Therefore, if there is another small role whose winning probability is lower than that of the watermelon, it is possible to increase the probability of being converted into a winning status notification command of other contents when the small role is won.

In addition, as shown in FIG. 8B, in the case of a big bonus, the winning status notification command generated based on the result of the internal lottery itself (the processing for conversion is not performed) It will indicate whether it is a win for a loser, watermelon or a win for a bell, a win for a cherry, a win for a cherry, or a JACIN win. Of these, a winning status notification command indicating a winning combination for all roles, winning a small role for watermelon, winning a small role for Bell, or winning a JACIN is not converted to a winning status notification command of other contents.

  In accordance with the winning status notification command indicating the winning of the cherry small role, and the random number acquired as described above, the winning status notification command indicating that all the roles have been lost is converted with a probability of 1/50621. The remaining 50620/50621 probabilities are not converted into winning status notification commands of other contents.

  The winning status notification command is transmitted from the game control board 101 to the effect control board 102 substantially at the timing when the internal lottery is performed, that is, when the start lever 11 is operated. On the game control board 101 side, rotation of the reels 3L, 3C, 3R is started based on the operation of the start lever 11. On the other hand, on the side of the production control board 102, production is started based on reception of the winning status notification command. For this reason, if the winning status notification command is transmitted at the same timing following the internal lottery, the rotation of the reels 3L, 3C, and 3R and the progress of the production will be synchronized, and depending on the content of the production, the player can select the reel 3L, The stop operation of 3C and 3R, that is, the pushing operation is assisted.

  Therefore, the CPU 111 of the game control board 101 uses the hardware random number function to extract a random number for delaying the transmission timing of the winning status notification command (delay processing random number), and the delay stored in the ROM 113 in advance. In accordance with a time table (a table in which a random number value and a time for delaying command transmission are stored in association with each other), a winning status notification command is transmitted to the effect control board 102, for example, for 0.1 seconds to 0.8 seconds. The range is delayed by a random period. Thereby, the rotation start timing of the reels 3L, 3C, and 3R and the start timing of the effect controlled on the effect control board 102 side are randomly shifted, and the two are not synchronized.

  Next, an effect performed on the effect control board 102 side will be described. The CPU 121 of the effect control board 102 drives the speaker driving circuit 131, the display driving circuit 132, and the lamp driving circuit 133, and the sound output from the speakers 7L, 7R, and 7U, the image displayed on the liquid crystal display 4, or The effect by the light by light emission of game effect lamps 75A-75M is performed. In addition to the announcement made at the time of winning the prize, the announcement will be made based on the winning status notification command to notify that the regular bonus or big bonus has been won. There is.

  In this slot machine 1, the notice effect and the notice effect include a three-game effect that is completed intermittently in a three-game period, in addition to a one-game effect that is completed in a one-game period. Completion of the three-game production has the meaning of notifying that the big bonus or the regular bonus has been won. The three-game production is divided into three, first, second, and third, but whether or not to execute the production at each stage is determined for each game, and is finished without completing to the end. May end up.

  The ROM 123 of the effect control board 102 stores in advance an effect selection table (described later) for determining what effects the CPU 121 performs for each game (each time the winning status notification command is received). . In addition, in order to determine an effect to be executed according to the effect selection table, the CPU 121 uses the hardware random number function including the random number generation circuit 125 and the sampling circuit 126 to generate an effect selection random number that can take a value in the range of 0 to 99. Is extracted. Furthermore, the RAM 122 is used to form an effect counter that counts up to which stage of the three game effects has been executed.

  FIG. 9 is a diagram showing an effect selection table stored in the ROM 123. The effect selection table differs depending on whether or not the value of the effect counter is 0 and whether or not the latest winning status notification command received indicates the winning of a big bonus or a regular bonus.

  When the value of the production counter is 0, that is, when no stage of the three-game production has been performed in the previous game or when the third stage has been completed, the latest winning status notification command is a big bonus or regular FIG. 9A shows an effect selection table that is applied when the bonus is won. As shown in the drawing, if the value of the random number for effect selection is 0 to 19, no effect is executed. If the value of the effect selection random number is 20 to 34, the notice effect as one game effect is executed. If the value of the effect selection random number is 35 to 39, a notification effect as one game effect is executed. If the value of the effect selection random number is 40 to 99, the first stage of the 3-game effect is executed.

  FIG. 9B shows an effect selection table that is applied when the latest win status notification command does not indicate the winning of the big bonus or the regular bonus even if the value of the effect counter is 0. As shown in the figure, if the value of the random number for effect selection is 0 to 97, no effect is executed. If the value of the effect selection random number is 98, the notice effect as one game effect is executed. If the value of the effect selection random number is 99, the first stage of the 3-game effect is executed.

  When the value of the production counter is not 0, that is, when the first or second stage of the three-game production is executed in the previous game, the latest winning status notification command indicates the winning of the big bonus or the regular bonus. FIG. 9C shows an effect selection table that is applied in the case of As shown in the figure, if the value of the random number for effect selection is 0 to 39, no effect is executed. If the value of the effect selection random number is 40 to 99, the next stage of the 3-game effect is executed.

  Furthermore, FIG. 9D shows an effect selection table applied when the value of the effect counter is not 0 and the latest winning status notification command does not indicate the winning of the big bonus or the regular bonus. As shown in the figure, if the value of the random number for effect selection is 0 to 98, no effect is executed. If the value of the effect selection random number is 99, the next stage of the 3-game effect is executed.

  Note that the execution time of the notice effect and the notice effect, which are one game effects, and the execution time of each stage of the three game effects are both 3.0 seconds or less. This is 0 which is the maximum value of the delay time of the winning status notification command from 4.1 seconds which is the minimum value of the time of one game timer (the timer which measures time from the start of rotation of the reels 3L, 3C and 3R in each game). The time obtained by subtracting 8 seconds is shorter than 3.3 seconds. By setting such a length, regardless of the game progress method of the player, each stage of the notice effect, the notice effect, and the three-game effect ends within one game period. In addition, the three-game effects are temporarily interrupted when the first or second stage is completed, and the second or third stage effects are resumed in the next game period. The stages are to be performed intermittently.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, “game” includes a series of processes from setting the bet amount to rotating / stopping the reels 3L, 3C, 3R. Furthermore, if any processing (for example, payout of medals or transition of gaming state) is performed after the rotation of the reels 3L, 3C, 3R is stopped, this is also included as processing within one game. To do.

  FIG. 10 is a flowchart showing processing for one game executed by the CPU 111 of the game control board 101. When the process of one game is started, an initial process is first performed (step S1). When a game is normally progressing, nothing is performed as an initial process. In other words, this initial processing is to check the settings, restore the backed up information, etc. when the power is turned on or when the error is restored.

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S2).

  When the bet number is set by the BET process and the start lever 11 is operated, the lottery process for determining whether or not the winning of each winning combination is allowed (step S3). Based on the lottery result in the lottery process, various winning flag commands are set in the RAM 112, and a winning status notification command indicating the winning status for each combination is sent to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process ends, a reel fluctuation start process is performed (step S4). In the reel fluctuation start process, the reels 3L, 3C, and 3R in the previous game are processed on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, 3R. The motors 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. Thereby, the symbols are variably displayed on the variable display device 2. If the predetermined time has not elapsed since the start of rotation in the previous game, the rotation display waits and the weight display unit 31 is notified by lighting the weight lamp 61. Note that the order of starting the rotation of the reels 3L, 3C, 3R may be changed according to the state of various flags set in the RAM 112. At the start of rotation, the reel stop timer and the timing of one game timer for the next game are started.

  Thereafter, reel fluctuation stop processing is performed (step S5). In the reel fluctuation stop process, after a predetermined condition is established from the start of reel rotation (the reference position is detected by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed), the stop buttons 12L, 12C , 12R is made effective, and the reel motors 3ML, 3MC, and 3MR are stopped by being operated by the player, and the rotation of the reels 3L, 3C, and 3R is stopped. At this time, based on the various winning flags set in the RAM 112 and the gaming state, the stop symbol is selected by pull-in control for controlling the driving stop of the reels 3L, 3C, 3R. Further, when a predetermined time (for example, 30 seconds) elapses for the time measured by the reel stop timer, the driving of the reels 3L, 3C, and 3R is forcibly stopped.

  When the driving of each of the reels 3L, 3C, 3R is stopped, whether or not any of the above-mentioned roles has been arranged on the active line corresponding to the bet number set in the BET process in step S2 in the display mode at the time of stopping. A winning determination process is performed (step S6). If it is determined in this winning determination process that a winning combination has been won, various settings corresponding to the type of winning are made on the game control board 101 and a winning information command is sent to the effect control board 102. Also, when the big bonus is ended, a big bonus end command 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, and the credit is increased by the number of payout scheduled medals 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 (step S7). Then, the process for one game ends, and the process for the next one game starts. If no payout scheduled medal number is set in the winning determination process, no process is performed as the medal payout process.

  Next, the lottery process in step S3 will be described in detail. FIG. 11 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3.

  First, a random number generated by the random number generation circuit 115 is sampled and acquired by the sampling circuit 116, and the acquired random number value is temporarily stored in the RAM 112 (step S101). Next, a start operation notification command indicating that the start lever 11 has been operated is temporarily set in a predetermined area of the RAM 112 (step S102). Then, the set start operation notification command is transmitted from the I / O port 114 to the effect control board 102 (step S103).

  Next, the random number temporarily stored in the RAM 112 in step S101 is set to the probability setting by the setting switch 91, the bet number set by the BET process in step S2, and the current gaming state (during normal, big bonus and regular bonus). The corresponding winning determination table is compared (step S104). As a result, it is determined whether or not any combination is won (step S105). If any winning combination is won, a winning flag corresponding to the winning winning combination is set in the RAM 112 (step S106), and the process proceeds to step S107. On the other hand, if no winning combination has been won, the process proceeds to step S107.

  In step S107, a winning status notification command corresponding to the lottery result (no winning or each winning type) is generated and temporarily set in a predetermined area of the RAM 112. Then, after the set winning status notification command is converted into a command having a content different from the original winning status with a predetermined probability as will be described later, the command is delayed by a random period and transmitted to the effect control board 102 (step). S108). Then, the lottery process ends.

  FIG. 12 is a flowchart showing in detail the command transmission process in step S108. First, it is determined whether or not the command to be transmitted is a winning status notification command (step S201). If the command to be transmitted is a winning status notification command, it is determined whether or not the current gaming state is a regular bonus based on the state of the regular bonus flag set in the RAM 112 (step S202). If it is during the regular bonus, it is converted into a winning status notification command indicating that it is out of all the combinations (step S203). Then, the process proceeds to step S208.

  If the regular bonus is not in effect, the first and second random numbers are acquired using the software random number function (step S204). Further, based on the big bonus medium flag set in the RAM 112, it is checked whether it is a normal gaming state or a big bonus (step S205), and the check result and the random number value obtained in step S204 are used. Based on this, it is determined whether or not the winning status notification command should be converted (step S206). That is, in the normal gaming state, the command is converted when the random number value is A, B, C, D, or E, and in the case of a big bonus, the command is converted when the random number value is E. To be.

  When the winning status notification command should be converted, the winning status notification command conversion table shown in FIG. 7 is referred to according to the value of the random number acquired in step S204, and the winning status notification command set in the RAM 112 according to the reference result Is converted (step S207), and the process proceeds to step S208. If the winning status notification command is not converted, the process proceeds to step S208.

  In step S208, a random number for delay processing is extracted using the hardware random number function. Further, the delay time corresponding to the extracted random number is read from the delay time table, and the process waits for the read delay time (step S209). Then, after the delay time ends, the winning status notification command set in the RAM 112 is transmitted from the I / O port 114 to the effect control board 102 (step S210). Then, the command transmission process ends, and the process returns to the process of FIG.

  If the command to be transmitted in step S201 is not a winning status notification command, the command to be transmitted is transmitted from the I / O port 114 to the effect control board 102 (step S211). Then, the command transmission process ends, and the process returns to the process of FIG.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs a transition of the game state between the normal game state, the regular bonus, and the big bonus, and controls the effects according to the progress of the game. It is transmitted to the substrate 102. On the other hand, the CPU 121 of the effect control board 102 performs an effect by an original process based on the command received from the game control board 101.

  FIG. 13 is a flowchart showing command reception processing executed by the CPU 121 of the effect control board 102. On the effect control board 102 side, it is determined whether or not the reception of the command sent from the game control board 101 has been received (step S301). Until the command is received, the processing in step S301 is repeated, and the command is waiting to be received.

  When any command is received from the game control board 101, it is determined what kind of the received command is (step S302). If the received command type is a winning information command sent when winning a winning combination, a winning process described later is executed (step S303). After the winning process is completed, the process returns to step S301.

  If the received command type is the winning status notification command sent in step S206, the winning status notification command is stored in the RAM 122. Here, since up to three winning status notification commands are stored, when three are already stored, the oldest one (however, an internal status notification command indicating that a bonus winning and a small role winning are not selected) Is stored in the RAM 122, and when the newly received winning status notification command does not indicate that the bonus is won, it is overwritten and saved (second oldest) (step S304). Thereafter, based on the three winning status notification commands stored in the RAM 122, an effect for notifying or notifying the bonus winning is executed (step S305). This effect process will be described later. When the presentation is finished, the process returns to step S301.

  If the received command type is another command, processing corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S306). Thereafter, the process returns to step S301.

  14 to 16 are flowcharts showing in detail the effect process in step S305. In the effect process, first, using the hardware random number function on the effect control board 102 side, any value in the range of 0 to 99 is obtained as an effect selection random number (step S401). Next, it is determined whether or not the latest winning status notification command stored in the RAM 122 in step S304 indicates that the big bonus or the regular bonus is won (step S402).

  If the winning of the big bonus or the regular bonus is indicated, it is determined whether or not the value of the effect counter is 1 (step S403). If the value of the effect counter is 1, the effect lottery is performed with reference to the effect selection table of FIG. 9C according to the value of the effect selection random number acquired in step S401 (step S404). As a result of the effect lottery, it is determined whether or not the execution of the 3-game effect has been won (step S405).

  When the execution of the three-game effect is won, the speaker drive circuit 131, the display drive circuit 132, and the lamp drive circuit 133 are controlled to output sound from the speakers 7L, 7R, 7U and display an image on the liquid crystal display 4. By causing the game effect lamps 75A to 75M to emit light, the second stage of the three-game effect is executed (step S406). When the execution of the second stage of the three-game effect is completed, the value of the effect counter is incremented to 2 (step S407). Then, the effect process ends, and the process returns to the process of FIG.

  If the value of the effect counter is not 1 in the determination in step S403, it is further determined whether or not the value of the effect counter is 2 (step S408). If the value of the effect counter is 2, as in the case where the value of the effect counter is 1, the effect is selected with reference to the effect selection table in FIG. 9C according to the value of the effect selection random number acquired in step S401. A lottery is performed (step S409). As a result of the effect lottery, it is determined whether or not the execution of the 3-game effect has been won (step S410).

  If the three-game effect is won, it is further determined whether or not all three winning status notification commands stored in the RAM 122 indicate that a big bonus or a regular bonus has been won ( Step S411). When all the winning status notification commands for the past three times indicate winning of a big bonus or a regular bonus, the third stage of the three-game effect is executed (step S412). When the third stage of the 3-game effect is completed, the value of the effect counter is cleared to 0 (step S413). Then, the effect process ends, and the process returns to the process of FIG.

  In addition, when the three-game effect is not won in the determinations in steps S405 and S410, or in the determination in step S411, the big bonus or the regular bonus is selected in the past three winning status notification commands. Is included in the current game, the three-game effect is not executed. In these cases, after the value of the effect counter is cleared to 0 (step S413), the effect process is terminated and the process returns to the process of FIG.

  If the value of the effect counter is not 2 in the determination in step S408, the value of the effect counter is 0, and the three-game effect is not executed during the previous game period. In this case, the effect lottery is performed with reference to the effect selection table of FIG. 9A according to the value of the effect random number acquired in step S401 (step S414). As a result of the effect lottery, it is determined whether or not the execution of the 3-game effect has been won (step S415).

  If the three-game effect is won, the first stage of the three-game effect is executed (step S416). When the first stage of the three-game effect is completed, the value of the effect counter is incremented to 1 (step S417). Then, the effect process ends, and the process returns to the process of FIG.

  If the execution of the three-game effect is not won, it is determined whether or not the notification effect is won as a result of the effect lottery in step S414 (step S418). If the notification effect has been won, it is further determined whether all three winning status notification commands stored in the RAM 122 indicate that a big bonus or a regular bonus has been won (step S419).

  If all the winning status notification commands for the past three times indicate winning of a big bonus or a regular bonus, a notice effect is executed (step S420). When the execution of the notification effect ends, the effect process ends, and the process returns to the process of FIG. If the winning status notification commands for the past three times include those that do not indicate that the big bonus or regular bonus has been won, the rendering process ends and the process returns to the process of FIG.

  If the announcement effect is not won, it is determined whether the notice effect is won as a result of the effect lottery in step S414 (step S421). If the execution of the notice effect is won, the notice effect is executed (step S422). When execution of the notice effect is finished, the effect process is finished, and the process returns to the process of FIG. If the execution of the notice effect is not won, the result of the effect lottery in step S414 is that there is no effect, and the effect process is terminated and the process returns to the process of FIG.

  If it is determined in step S402 that the latest winning status notification command does not indicate that the big bonus or the regular bonus is won, it is determined whether or not the value of the effect counter is 1 (step S423). If the value of the effect counter is 1, the effect lottery is performed with reference to the effect selection table of FIG. 9D according to the value of the effect selection random number acquired in step S401 (step S424). As a result of the effect lottery, it is determined whether or not the execution of the 3-game effect has been won (step S425).

  If the three-game effect is won, the second stage of the three-game effect is executed (step S426). When the execution of the second stage of the three-game effect is completed, the value of the effect counter is incremented to 2 (step S427). Then, the effect process ends, and the process returns to the process of FIG.

  If the value of the effect counter is not 1 in the determination in step S423, it is further determined whether or not the value of the effect counter is 2 (step S428). If the value of the effect counter is 2, the value of the effect counter is cleared to 0 without executing the third stage of the 3-game effect (step S429). Also, if the three-game effect is not won in the determination in step S425, the value of the effect counter is cleared to 0 (step S429). Then, the effect process ends, and the process returns to the process of FIG.

  If the value of the effect counter is not 2 in the determination in step S428, the value of the effect counter is 0, and the three-game effect is not executed during the previous game period. In this case, the effect lottery is performed with reference to the effect selection table of FIG. 9B according to the value of the effect random number acquired in step S401 (step S430). As a result of the effect lottery, it is determined whether or not the execution of the 3-game effect has been won (step S431).

  When the execution of the 3-game effect is won, the first stage of the 3-game effect is executed (step S432). When the first stage of the three-game effect is completed, the value of the effect counter is incremented to 1 (step S433). Then, the effect process ends, and the process returns to the process of FIG.

  If the three-game effect has not been won, it is determined whether or not the notice effect has been won as a result of the effect lottery in step S430 (step S434). If the execution of the notice effect is won, the notice effect is executed (step S435). When execution of the notice effect is finished, the effect process is finished, and the process returns to the process of FIG. If the execution of the notice effect is not won, the result of the effect lottery in step S430 is that there is no effect, and the effect process is terminated and the process returns to the process of FIG.

  Hereinafter, execution of effects in the slot machine 1 according to this embodiment will be specifically described.

  FIG. 17 is a diagram showing the relationship between the contents of the winning status notification command and the effect to be executed. Here, the received winning situation notification command indicates what kind of effect (one stage of the three-game effect) is executed in each game within the period of three games from the game ended without effect. Or, the case where the regular bonus is won and the case where it is not, will be described separately.

  When the winning status notification command received after the game without the performance indicates the winning of the big bonus or the regular bonus, the first of the three game effects with a probability of 6/10 as the effect of the game (first game). One stage is performed. Also, there is no effect with a probability of 2/10, a notice effect with a probability of 3/20, and a notification effect with a probability of 1/20 (however, the winning status notification commands for 3 times set in the RAM 122 will be Will be executed only if winning is also shown). If there is no effect here, or if a notice effect or a notice effect is executed, the effect of the next game can be considered in the same way.

  If the winning status notification command received after the game in which the first stage of the three-game effect is executed indicates that the big bonus or the regular bonus is won, three games with a probability of 6/10 as the effect of the game The second stage of production is executed. With the remaining 4 / 10th probability, there is no production. That is, the probability that the three-game effect is canceled in the first stage is 24/100. Note that the production of the next game when there is no production can be considered in the same manner as in the first game.

  If the winning status notification command received after the game in which the second stage of the three-game effect is executed indicates that the big bonus or the regular bonus is won, the third stage of the three-game effect has a probability of 6/10. Will be executed, and there will be no effect with the remaining 4/10 probability. That is, the probability that a three-game effect is executed and completed up to the third stage is 216/1000, and the probability that it is canceled in the second stage is 144/1000.

  Further, when the winning status notification command received after the game without the production does not indicate the winning of the big bonus or the regular bonus, the three-game production with a probability of 1/100 as the production of the game (first game). The first stage is executed. Further, there is no effect with a probability of 98/100, and a notice effect is executed with a probability of 1/100. If there is no effect here or if a notice effect is executed, the effect of the next game can be considered in the same way.

  If the winning status notification command received after the game in which the first stage of the three-game effect is executed does not indicate the winning of the big bonus or the regular bonus, the three-game with a probability of 1/100 as the effect of the game The second stage of production is executed. With the remaining 99 / 100th probability, there is no production. That is, the probability that the three-game effect is canceled in the first stage is 99 / 10,000. Note that the production of the next game when there is no production can be considered in the same manner as in the first game.

  If the winning status notification command received after the game in which the second stage of the three-game effect is executed does not indicate the winning of the big bonus or the regular bonus, the effect is not executed in the game. That is, the probability that the three-game effect is canceled in the second stage is 1/10000.

  As described above, the first stage and the second stage of the three-game effect are executed regardless of whether the winning status notification command indicates the winning of the big bonus or the regular bonus. It will be a thing. The third stage of the three-game production has a meaning as a notice production because it is executed only when the winning situation notification command indicates that the big bonus or the regular bonus is won. Here, in the case where the first and second stages of the three-game production are executed, the ratio when the winning status notification command does not indicate the winning of the big bonus or the regular bonus is smaller in the second stage. Therefore, the second stage of the three-game effect has a meaning as a more reliable notice effect than the first step.

  In addition, at the stage where the first stage or the second stage of the three-game production is completed, there is a case where the winning status notification command is changed from one not showing the big bonus or regular bonus winning to one showing the winning, Since there are very few cases like this, it is almost negligible when considering the reliability as the notice effect of the first stage or the second stage of the three-game effect.

FIG. 18 is a diagram illustrating an execution example of the 1-game effect and the 3-game effect. Here, only the final result of one game effect or the final result of each stage of the three game effect is shown as an example only of the effect by the image displayed on the liquid crystal display 4.
The notice effect as one game effect is completed within the period of one game from the start, and “This is ambiguous” is displayed as a final result, for example, as shown in FIG. Similarly, the notification effect as one game effect is completed within one game period from the start, and the final result is displayed as “bonus confirmation”, for example, as shown in FIG.

  On the other hand, the three-game effect ends only up to one stage within the period of one game from the start. At the end of the first stage, for example, as shown in FIG. 18 (c), “This is suspicious? Let's take a look a little more” is displayed, indicating that this effect continues. Further, at the end of the second stage, for example, as shown in FIG. 18 (d), the message “Isn't it really wrong? Let's see a little more” is displayed, indicating that this effect will continue further here. When the third stage is completed, as a final result of the three-game production, for example, as shown in FIG. 18 (e), “As expected, the bonus is determined!” Is displayed.

  As described above, in the slot machine 1 according to this embodiment, the CPU 111 of the game control board 101 simply sends the winning status notification command indicating the result of the internal lottery in each game to the effect control board 102. It has not been determined whether or not to execute, and what kind of production will be executed. This determination can be performed independently by the CPU 121 of the effect control board 102 for each game based on the winning status notification command received from the game control board 101. For this reason, the processing load is not applied to the CPU 111 and other circuits on the game control board 101 side in order to determine the execution of the effect. Since the random number generation for determining the execution of the production is also performed using the hardware random number function that the production control board 102 has uniquely, a processing load may be applied to the circuit on the game control board 101 side. Absent.

  In addition, the winning status notification command transmitted from the game control board 101 to the effect control board 102 has been modified to show a content different from the original internal lottery result with a predetermined probability. Thereby, it is possible to prevent the result of the internal lottery from being captured from the outside. Furthermore, since the transmission timing of the winning status notification command to the effect control board 102 is delayed by a random period, the rotation of the reels 3L, 3C, 3R and the effect executed on the effect control board 102 side may be synchronized. In addition, the stop operation timing (so-called pressing timing) is not suggested to the player depending on the contents of the performance.

  Further, the effects executed on the effect control means 102 side include a 1-game effect that is completed in the period of one game and a 3-game effect that is completed in the period of 3 games, and there are many variations of effects. In addition, since each stage of the game determines whether or not to execute each stage of the three-game production, the three-game production may be interrupted in the middle, resulting in a large number of production variations. Thereby, the interest of a game can be improved.

  Here, the one-game production is completed during one game period, and the final result of the production (whether the announcement of the big bonus or regular bonus is won or announced) is shown to the player. The result of the production is easy to understand.

  On the other hand, the three-game production is completed in the period of three games, but each stage of the production is performed intermittently corresponding to each game. In this way, the player is not bored for a long time, so the player is not bored. Moreover, since each stage forms a series of series, the content of the production can be unified and the interest of the game can be improved. Since the final stage of the three-game production is a big bonus or regular bonus winning announcement, performing for a long period of time results in an increase in the fun of the game.

  Note that the winning status notification command may indicate a different content from the result of the internal lottery, but the final stage of the announcement effect or the three-game effect is to win the big bonus or regular bonus. This is only when the winning status notification command indicating is received three times in succession. The probability that a winning status notification command is transmitted so as to indicate the winning even though the big bonus or the regular bonus is not originally won is very small, and the probability of continuing three times is extremely close to zero. Even if there are three consecutive cases, there are fewer cases where the final stage of the notice effect or the three game effect is executed. In other words, the probability that the announcement stage and the final stage of the three-game stage will be executed even though the big bonus or regular bonus is not originally won is very small compared to the probability that other errors will occur. The problem does not occur.

  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-described embodiment, there are one game effect that is completed in one game period and three game effect that is completed intermittently in three game periods as a notice effect or a notice effect. However, the effects that are completed in a period of a plurality of games are not necessarily limited to three games, and can be effects that are completed in an arbitrary period of two or more games. Further, each stage of the three-game production is fixed, but this can be changed dynamically for each game.

  FIG. 19 is a diagram illustrating another execution example of the three-game effect. In this example, there is only one pattern as the first stage. At the end of the pattern, for example, as shown in FIG. 19 (a), “This is suspicious? It is shown that this production continues further.

  In the period of the next game in which the first stage is executed, the second stage is executed if a lottery of three game effects is won, but three patterns are provided as the second stage. . As shown in FIG. 19B, the first pattern of the second stage is shown only as “What! Bonus is confirmed!” And does not indicate that this effect will continue further. As shown in FIG. 19 (c), the second pattern is displayed as “Is it pretty suspicious? Let's take a look a little more”, indicating that the production continues further here. As shown in FIG. 19 (d), the third pattern is “What is wrong, sorry!” And does not indicate that this effect will continue further.

  In the period of the next game in which the second stage is executed with the second pattern, the third stage will be executed if the three-game effect lottery is won, but there are also three patterns as the third stage. Is provided. As shown in FIG. 19 (e), the first pattern of the third stage shows only “as expected! As shown in FIG. 19 (f), the second pattern is displayed as “I'm afraid but ... I don't know!”. As shown in FIG. 19D, the third pattern is displayed as “Are you different? Really sorry!”. In the third pattern, it is not shown that this effect continues further.

  In the three-game production in this execution example, the first pattern, the second pattern in the second stage, and the second pattern in the third stage have a meaning as a notice effect. Further, the first pattern in the second stage and the first pattern in the third stage have a meaning as a notice effect. By performing the three-game effects in this way, it is possible to further increase the variations of the effects and improve the interest of the game.

  In the above embodiment, each stage of the three-game production is performed intermittently corresponding to each game, but each stage may be continuous. In order to perform each stage continuously, after the first stage or the second stage of the three-game stage is finished, it is in an idle state (for example, the screen is shaken or the color is continuously changed) until the next stage is decided. It is sufficient to make it stand by in the state of changing it automatically. Alternatively, the effects at each stage may be contents that circulate.

  In the above embodiment, the content of the winning status notification command transmitted from the game control board 101 to the effect control board 102 is converted to a different one from the result of the internal lottery with a predetermined probability. However, the winning status notification command may notify the effect control board 102 of the result of the internal lottery as it is in any case. In this case, the final stage of the notice effect and the three-game effect can be executed only by receiving the command indicating the winning of the big bonus or the regular bonus once.

  Also, if the probability that the content of the winning status notification command is converted is low, the final stage of the notification effect or the three-game effect is executed if the command indicating the winning of the big bonus or the regular bonus is received twice in succession. If there is a high probability that the contents of the winning status notification command will be converted, a notification effect or a three-game effect will be given only when the command indicating the winning of the big bonus or the regular bonus is continuously received more times. The final stage of the process may be executed.

  In the above embodiment, the gaming state of the slot machine 1 has only a big bonus and a regular bonus in addition to the normal gaming state. On the other hand, AT (notifying the type of the selected small role), CT (those whose reel stop is in an uncontrolled state), RT (those having a replay winning probability higher than normal), ST It may include other advantageous specific gaming states such as (including AT and RT) and push order navigation (instructing the order of operating the stop buttons 12L, 12C, and 12R).

  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.
