Description

  The present invention relates to a pachinko gaming machine that executes a special game operation that opens and closes a big prize opening when a start memory is generated as a game ball flows into the start port and is confirmed by the digestion of the start memory. is there.

  As a pachinko machine, the special symbol starts to fluctuate by digesting the starting memory that accompanies the inflow of the game ball to the starting port, and the winning prize opening is opened and closed when the winning pattern is determined by the stop pattern A special game operation that repeats an open / close round is widely known. The state in which the special game operation is being executed is an opportunity for a player to obtain a large profit because a lot of prize balls are likely to be generated according to the prize winning in the big prize opening.

  Here, in general, a probability of stopping in a stop symbol mode in which a special symbol is hit and fixed (hereinafter referred to as winning probability) is set in advance, and processing is performed so as to determine a win or a loss based on the winning probability doing. The winning probability is only a probability that the special symbol is hit and fixed. For example, when the symbol is preset such as 1/100 or 1/300, the number of fluctuations of the special symbol (the number of times the symbol generation process is executed) 100 There is no guarantee that a winning will occur at a rate of once per 300 times or 300 times. Therefore, even if the number of executions of the special symbol design generation process exceeds 100 times or 300 times, it may not be determined. However, most of the players are playing games with the expectation that they will be confirmed once at a rate of 100 times or 300 times of the symbol generation process based on the winning probability. Therefore, if the symbol generation process does not occur even if the number of executions of the symbol generation process is increased, the irritability and irritability are likely to be induced. In order to solve such a problem, a configuration has been proposed in which when a predetermined ceiling condition is satisfied, a winning hit is determined regardless of the winning probability (for example, Patent Document 1). Here, if the ceiling condition that is established when the number of symbol generation process executions reaches a predetermined number of times is set, even if the number of symbol generation process executions to be confirmed increases, the hit determination is guaranteed. Therefore, the above-mentioned impatience and irritation can be suppressed.

JP 2004-16703 A

  In the conventional configuration of the above-mentioned Patent Document 1, since the hitting is confirmed regardless of the winning probability when the ceiling condition is established, the winning is surely determined by increasing the number of times of performing the symbol generation process for determining the loss. is there. Although this can give the player a sense of security and can suppress the above-mentioned impatience and irritability, it impairs the original gameplay of pachinko games, which determines either winning or losing according to the winning probability. It can be said that it is a thing. Also, even if it is difficult for the player to know the time of hitting by changing the ceiling conditions as appropriate, the hitting is determined by the establishment of the ceiling condition, so the above-mentioned problem of impairing the gameability is not solved. Remain in.

  The present invention proposes a pachinko gaming machine that can suppress an increase in a player's irritability due to continuous execution of a lost symbol generation process without impairing the game performance of the pachinko game. Is.

  The present invention relates to a symbol display device that variably displays a special symbol, a start opening provided with a ball detecting means for detecting a winning of a game ball, and the ball detecting means of the start opening detects a game ball, thereby determining a predetermined number. The start memory generating means for generating and storing the start memory as the upper limit, and the undigested start memory are sequentially digested, so that the special symbol fluctuates on the symbol display device and stops in a stop symbol mode in which the winning or losing is determined. In a pachinko gaming machine having a game control means for executing a special game operation for opening and closing a special winning opening in a predetermined manner when a series of symbol generation processes are executed and a winning stop symbol aspect is fixed, the game control means In this process, a plurality of winning probability states with different winning probabilities are sequentially set, and the number of consecutive executions of the symbol generation process in which the current winning probability state has been confirmed is valid in the winning probability state. By exceeding the inverse of the rate, a pachinko machine, characterized in that those having the winning probability setting processing for setting the winning probability state higher winning probability compared to the winning probability is defined.

  Here, the winning probability setting process is preferably a process in which the timing for sequentially setting the winning probability state is a timing at which the number of consecutive executions of the symbol generation process reaches a predetermined number of times equal to or greater than the reciprocal of the winning probability. As the predetermined number of times greater than or equal to the reciprocal of the winning probability, the number of times that is the next integer of the reciprocal, the number of times determined based on the reciprocal, and the like can be appropriately set. However, it is preferable to set the upper limit so that the predetermined number of times greater than or equal to the reciprocal number does not become too large compared to the reciprocal number. For example, the upper limit is preferably 1.1 to 1.5 times the reciprocal number. .

In addition, the reciprocal of the winning probability described above may be a number having not only an integer but also a decimal point. For example, if the winning probability is 3/100, the reciprocal is a number having a decimal point. The winning probability 1 / m is expressed as an expected value at which a win (event) can occur once for m lottery times (trials). That is, the winning probability setting process of the present invention executes a process of setting the next winning probability state when the winning probability is 1 / m and the number of consecutive executions exceeds the inverse m. Each winning probability in this case can be set as 1 / m ₀ , 1 / m ₁ , 1 / m ₂ ... (M ₀ > m ₁ > m ₂ >...).

  In such a configuration of the present invention, the number of consecutive executions of the lost symbol generation process exceeds the reciprocal of the winning probability, so that the next winning probability state is set. Since the probability increases, it becomes easier to determine and win special symbols. As described above, the player has an expectation that the winning probability 1 / m will be confirmed once per m times of the symbol generation process, but in actuality, the symbol generation is more than m times. Even if the process is executed, there is a case where the player's expectation cannot be satisfied without being hit. On the other hand, according to the configuration of the present invention, the winning probability rises when the reciprocal of the winning probability exceeds the number of consecutive executions of the symbol generation process, so that even if the player's expectation for the winning probability is not satisfied, , Can stimulate the sense of expectation of hitting, and can increase the willingness to play. As a result, an increase in the number of consecutive executions of the symbol generation process that has been determined to be lost can suppress impatience and annoyance that is not determined.

  Furthermore, since the winning probability setting process is performed so as to set the next winning probability state after executing the symbol generation process of the number of consecutive executions corresponding to the number of trials representing the winning probability, The gameability that is expected to be confirmed is kept stable and fair, and the original gameplay of pachinko games can be maintained.

  In this configuration, when the winning probability setting process ranks a plurality of winning probability states having mutually different winning probabilities according to the winning probability, the current winning probability among the plurality of winning probability states. A process of sequentially setting each winning probability state is preferably used so as to select a winning probability state having a winning probability that is one higher than. Thereby, since the winning probability increases stepwise as the number of continuous executions of the symbol generation process increases, the above-described operational effects of the present invention can be more appropriately exhibited.

  In addition, in this configuration, when the symbol generation process that has been confirmed to be lost is continuously executed, the continuous number of times is determined as the number of continuous executions. The number of continuous executions is interrupted. Therefore, if the winning process is confirmed in the symbol generation process, the winning probability state is set so that the winning probability becomes higher in order by setting the winning probability state of the predetermined winning probability after the special game operation to be executed is completed. A configuration in which processing is executed is preferable.

  In the pachinko gaming machine of the present invention described above, when the winning probability setting process of the game control means is in the upper limit winning probability state of a predetermined upper limit winning probability that the probability of winning is smaller than 1, A configuration is proposed that includes a process for maintaining the upper-limit winning probability state until the hit is determined in the generation process.

  In such a configuration, the upper limit winning probability is set as a probability smaller than 1, and the winning probability higher than the upper limit winning probability is not set. Therefore, whenever the symbol generation process is executed, A state where the hit is fixed is not generated. Therefore, the operational effect of the present invention for maintaining the above-described pachinko game main body can be more appropriately exhibited. Here, the upper limit winning probability can be set as appropriate, for example, in a configuration including a game for converting to a probability-changing gaming state with a high probability of winning, which is equal to the winning probability of the probability-changing gaming state or It is preferable to set to a predetermined probability approximating this.

  In the pachinko gaming machine of the present invention described above, a configuration is provided that includes notifying means for notifying the setting timing for setting the next winning probability state when the number of consecutive executions reaches the reciprocal of the winning probability.

  Here, as a notification mode to be notified by the notification means, a notification mode by lighting or blinking display of LEDs or the like, a notification mode for displaying a predetermined symbol on the screen of the image display, and a voice notification mode are applicable.

  In addition to the set timing, a configuration in which the notification means notifies the number of continuous executions of the symbol generation process can be suitably used. As a notification mode of the number of continuous executions, notification may be made every time the number of continuous executions increases once, or may be notified every time a predetermined number of times increase. Furthermore, the number of continuous executions may be divided into a plurality of sections, and the notification mode may be changed for each section. Moreover, you may make it alert | report when the notification aspect of the continuous execution frequency reaches | attains the predetermined continuous execution frequency close | similar to setting timing.

  In such a configuration, since the player can clearly know when to switch to a high winning probability by notifying the setting timing for setting the next winning probability state, it is said that profit can be obtained by reaching the setting timing The game is recognized by the player, and the motivation and expectation for the profit acquisition can be stimulated effectively. In particular, when the number of continuous executions described above is notified, the player can clearly know how the number of continuous executions approaches the set timing. Can be stimulated more effectively. Thereby, the effect which suppresses the impatience and the irritation feeling which may arise when the frequency | count of the continuous execution of the symbol production | generation process which carries out a loss increase increases further.

  In the pachinko gaming machine according to the present invention described above, the winning probability setting process of the game control means calculates the reciprocal number of the winning probability that the number of consecutive executions of the symbol generation process that is confirmed to be lost in the winning probability state is valid in the winning probability state. If exceeded, a configuration is proposed that includes a process of delaying the setting timing for setting the next winning probability state until the symbol generation process having a predetermined number of delays is executed.

  According to such a configuration, since the setting timing of the winning probability state is determined by the number of delays, the setting timing is stably determined, and the winning probability is improved stepwise as the number of consecutive executions increases. A player can be given a sense of security with respect to other games. Thereby, the player's reliability can be ensured for a game in which each winning probability state is sequentially set so that the winning probability becomes higher in order.

  As the number of delays, a predetermined constant value may be set, or a value determined based on the winning probability may be set. In the former case, it can be set, for example, 10 times or 20 times, and in the latter case, it can be set as 10% or 20% of the reciprocal of the winning probability.

  As described above, the present invention enables the winning probability having a high probability of being confirmed and winning as compared with the winning probability, when the number of consecutive executions of the lost symbol generation process exceeds the reciprocal of the winning probability. Since a plurality of winning probability states are set sequentially, the number of consecutive executions of the symbol generation process exceeds the reciprocal number, so that even if the player's expectation of winning the hit based on the winning probability is not satisfied. Since an improvement in the winning probability can stimulate a sense of expectation for winning, the motivation for the game can be increased. In addition, in the configuration of the present invention, the winning probability is improved when the number of consecutive executions exceeds the reciprocal number, so that the original gaming nature of a pachinko game that expects to be confirmed by the winning probability can be stably maintained. Therefore, it is possible to suppress the impatience and irritation that occur when the number of consecutive executions of the symbol generation process for which the loss has been determined increases while maintaining the gameability of determining the winning or the loss based on the winning probability.

Note that the basic operation of the pachinko gaming machine 1 of the present embodiment is the same as that of the existing pachinko gaming machine, and thus detailed description thereof is omitted.

  When a game ball is launched by the ball launcher 41 in accordance with the turning operation of the launch handle 9 by the player, the game ball rolls down the game area 12 of the game board 10. Then, when the game ball flows into the starting port 21 of the above-described ordinary electric accessory 20, a random number lottery is performed from various tables, and a special starting memory for a special symbol is generated (see the winning detection process in FIG. 4). Then, as the special start memory is digested, the special symbol display device 15 blinks the LED, and the special symbol starts to change (see the special symbol process in FIG. 5). When a predetermined time elapses from the start of the fluctuation, the special symbol is fluctuated and the stopped symbol form is determined. In this way, a series of symbol generation processes from the start of variation of the special symbol to the fixed stop is executed by digesting the special start memory. Here, if the stop symbol mode of the special symbol is a hit stop symbol mode, a big hit is made and a special game operation described later is executed.

  The special start memory is composed of a data aggregate of a plurality of random values extracted from various tables for special symbols stored in the storage device ROM, and the plurality of random values flow into the start port 21. The detected game balls are respectively extracted by the special start switch S1 built in the ordinary electric accessory 20 (see the winning detection process in FIG. 4). Each random value constituting the special start memory is used for determining whether or not a special symbol is winning, a variation / stop mode of the symbol, an effect mode, and the like. By digesting such a special start memory (refer to the start memory digest process in FIG. 6), the big hit random value of the start memory is determined to be successful, and if the determination result is a hit, the hit stop is performed according to other random number values. The process (variation effect mode selection process in FIG. 6) of selecting the variation effect pattern of the effect (fluctuation effect mode) executed in the symbol mode or the symbol generation process is performed. Then, in the symbol generation process, the special symbol display device 15 changes and stops the special symbol, and the image display unit 14 or the like executes the variation effect mode according to the variable effect pattern (see the special symbol process in FIG. 5).

  When the special symbol fluctuated in the special symbol display device 15 is confirmed and stopped in a hit stop symbol form, a special game operation is executed in accordance with a big prize opening process (not shown). The special game operation is an operation in which an open / close round in which the special winning opening 25 is opened and closed is executed a predetermined number of times, and as described above, the special game is started when the special symbol stops in a hit / stop symbol form and becomes a big hit. Thereafter, the special game operation is completed by completing a predetermined number of open / close rounds. Here, one open / close round is completed by satisfying either the 30-second opening of the special winning opening 25 or 9 winnings.

Specifically, the special start memory generated during the change of the special symbol and the execution state of the special game operation is not immediately digested but is stored and held in the special start storage area. Here, a predetermined number (four) of special start memories can be held in the special start storage area. The number of undigested special start memories stored and held in the special start storage area is notified by the number of lighting of the special start memory number display device 17 described above. When the undigested special start memory held in the special start memory area is digested, the special start memory is read and erased from the special start memory area, and one LED of the special start memory number display device 17 is provided.

  The main control board 60, the sound source control board 66, and the light source control board 67 constitute start memory generation means according to the present invention, and execute the above-described winning detection process of FIG. Further, the main control board 60 and the effect control board 62 (image control board 65, sound source control board 66, light source control board 67) constitute the symbol control means according to the present invention, and execute the special symbol processing of FIG. To do. Furthermore, the above-described main control board 60 constitutes game control means according to the present invention.

Next, the main part of the present invention will be described.
As described above, by digesting the undigested special startup memory by the special symbol processing of FIG. 5 (and the startup memory digestion processing of FIG. 6), a series of symbol generation processes for changing and stopping the special symbol is executed. The Here, with the digestion of the special start memory, the big hit random number value constituting the special start memory is determined to win, and the winning or losing is determined in the symbol generation process according to the determination result. As described above, the jackpot random number value is extracted from the jackpot random number table in accordance with the game ball winning at the start port 21.

  As described above, the jackpot random number table is composed of 300 values from 0 to 299, and the winning determination is made based on whether or not the jackpot random number value extracted from the table matches a predetermined winning value. That is, the winning probability is determined according to 300 values in the jackpot random number table and the number of winning values.

  Here, in the present embodiment, five types of winning value groups in which a plurality of winning values are set are set. Specifically, a first winning value group composed of three preset winning values (for example, “7, 77, 177”) and six predetermined winning values (for example, “7, 77”). , 107, 177, 207, 277 "), a third winning value group including nine preset winning values, and twelve predetermined winning values. A fourth winning value group composed of values and a fifth winning value group composed of 15 preset winning values are set. When the first winning value group is valid, the winning probability is 1/100 (= 3/300), and when the second winning value group is valid, the winning probability is 2/100 (= 6 / 300), when the third winning value group is valid, the winning probability is 3/100 (= 9/300), and when the fourth winning value group is valid, the winning probability is 4 / 100 (= 12/300), and when the fifth winning value group is valid, the winning probability is 5/100 (= 15/300). That is, each winning value group is determined in order according to the winning probability so that the winning probability increases in order from the first winning value group.

  The process of determining whether or not to win the jackpot random number value by validating any one of the first to fifth winning value groups described above is performed by the start-up memory digesting process of FIG. In the start memory digestion process, when the special start memory is stored (the special symbol process of FIG. 5), the special start memory stored first is digested, and the big hit random number value is determined to be a winner. When a loss determination is made by this winning determination (big hit flag = 0), the loss is confirmed in the symbol generation process. The number of times that the symbol generation process for determining the loss in this way has occurred continuously is indicated as the number K of continuous executions. In the case of this embodiment, the continuous execution count K is incremented by 1 every time the special start-up memory is consumed, and is reset when the hit determination is made by the winning determination. Then, as the number of continuous executions K increases, processing for sequentially validating the first to fifth winning value groups is performed. In this process, when the number of consecutive executions K exceeds the reciprocal of the above-described winning probability determined by each winning value group, the winning value group having the next highest winning probability is made valid.

  In this embodiment, a winning effective value F that is incremented by 1 every time the number K of consecutive executions exceeds the reciprocal of the winning probability is set, and each winning value group is sequentially enabled according to the winning effective value F. Yes. The winning effective value F is reset when the winning determination is made by the winning determination described above. Therefore, when the special start memory is digested after the above-mentioned special game operation is completed, the winning winning value F = 1 is set to the first winning value. Make the group valid and make a winning decision. In the case where the first winning value group is made valid by the winning effective value F = 1, the winning probability is 1/100 and the reciprocal number 100 (= 100 / F) is exceeded until the continuous execution number K exceeds The winning effective value F = 1 is maintained. As a result, the winning probability of the jackpot random number value is 1/100 until the symbol generation process in which the loss is determined by digesting the special start memory is continuously executed 100 times. Thereafter, when the continuous execution count K exceeds 100 and becomes the 101st, the winning effective value F = 2, the continuous execution count K is reset, the second winning value group is enabled, and the big hit random number value is determined to win. As a result, the winning probability is 2/100 (= 1/50), and the winning probability of the big hit random number value is 2/100 until the continuous execution count K exceeds 50, which is the reciprocal of the winning probability 2/100. It is. Thereafter, when the number of consecutive executions K exceeds 50 and becomes the 51st, the winning effective value F = 3, the continuous execution number K is reset, the third winning value group is enabled, and the winning probability is 3/100. Similarly, when the continuous execution count K exceeds 33.3... (= 100/3) and becomes the 34th after this, the winning effective value F = 4 and the continuous execution count K is reset. The winning value group is valid and the winning probability is 4/100. Similarly, if the number of consecutive executions K thereafter exceeds 25 (= 100/4), the fifth winning value group is validated with the winning effective value F = 5.

  In this embodiment, the winning probability 5/100 (= 1/20) based on the fifth winning value group is set as the upper-limit winning probability. When the fifth winning value group is valid, the fifth winning value group is maintained even if the continuous execution count K exceeds 20 times which is the reciprocal of the winning probability. On the other hand, in any state in which any of the first to fifth winning value groups is valid, if the big hit random number value is hit, the winning effective value F and the continuous execution count K are reset. Therefore, after the expiration of the special game operation, the first winning value group is made valid by the winning effective value F = 1.

  Further, in this embodiment, when the undigested special start memory is not stored and the game ball is not fired, the elapsed time is measured, and when the elapsed time reaches a predetermined time, the number of consecutive executions K and the winning combination are measured. The effective value F is reset. This prevents the subsequent player from receiving profits due to the continuous execution count K accumulated by the previous player when the player changes. Here, the predetermined time of the elapsed time set for resetting can be appropriately set such as 5 minutes or 10 minutes.

  Furthermore, in this embodiment, as shown in FIG. 7, the number K of continuous executions of the above-described symbol generation process is displayed on the screen of the image display 14 by the level gauge symbol x. This level gauge symbol x displays the number of consecutive executions K increased by one when the symbol generation process is finalized after losing. Further, an ascending timing symbol y indicated by the reciprocal of the winning probability for validating the next winning value group is displayed as accompanying the level gauge symbol x. The rising timing symbol y is displayed so that the position corresponding to the reciprocal of the winning probability is indicated by the winning effective value F of the level gauge symbol x, and the display position changes as the winning effective value F changes. Such display processing of the level gauge symbol x and the rising timing symbol y is performed by the execution number display processing of the special symbol processing of FIG.

  In the configuration of the present embodiment, each of the first to fifth winning value groups having different winning probabilities is processed by increasing the number K of continuous executions of the symbol generation process. The state in which the winning value group is valid is the winning probability state according to the present invention. That is, a state in which the first winning value group is made effective by the winning effective value F = 1, a state in which the second winning value group is made effective by the winning effective value F = 2, and a third winning value group by the winning effective value F = 3 5 winning probability states can be set: a state in which the fourth winning value group is enabled by the winning effective value F = 4, and a state in which the fifth winning value group is enabled by the winning effective value F = 5. It has become. The winning probability setting processing according to the present invention is configured by starting memory digestion processing (special symbol processing) for determining whether or not each winning value group is valid and determining whether or not the jackpot random number value is won. The winning probability according to the fifth winning value group is the upper-limit winning probability according to the present invention, and the state in which the fifth winning value group is valid is the upper-limit winning probability state according to the present invention. On the other hand, the execution number display process for displaying the level gauge symbol x and the rising timing symbol y is executed by the main control board 60 and the effect control board 62, and the main control board 60 and the effect control board 62 are executed. The image display unit 14 constitutes a notification unit according to the present invention. Here, the rising timing pattern y notifies the setting timing for setting the winning probability state.

  A process for converting the winning probability of such a jackpot random value according to the increase in the number of consecutive executions K will be described as the game progresses. When the pachinko game is started after resetting the continuous execution count K and the winning effective value F, if the special start memory is digested, the first winning value is obtained by adding 1 to the continuous execution count K and the winning effective value F = 1. The group is validated and the jackpot random value is determined to win. If the result of the winning determination is a loss, the symbol generation process for maintaining the number of consecutive executions K and determining the loss is executed. Here, since the winning probability of the first winning value group is set to 1/100, the special start memory is stored until the continuous execution count K exceeds 100 times (= 100/1) which is the reciprocal of the corresponding selection probability. The first winning value group is validated as a result of the digestion, and the winning judgment is made. Here, on the image display 14, a level gauge design x displaying the number of consecutive executions K and a rising timing design y displaying the position of 100 times based on the winning effective value F = 1 are displayed. The level gauge symbol x is displayed so as to gradually increase by continuously executing the symbol generation process for determining the loss. When the continuous execution count K exceeds 100, the winning effective value F = 2, and the big hit random number value is determined to win by the second winning value group. This winning determination is made with a winning probability of 1/50, and the player can know from the level gauge symbol x and the rising timing symbol y that the winning probability has increased from 1/100 to 1/50. And the state of the winning effective value F = 2 with the winning probability 1/50 is maintained until the symbol generation process for determining the loss is executed 50 times, and the winning determination is made by the second winning value group. When the winning effective value F = 2, the display position of the rising timing symbol y is changed. When the symbol generation process for determining the loss with the winning effective value F = 2 exceeds 50, the winning effective value F = 3 and the winning random number is won by the winning probability 1 / 33.33 of the third winning value group. judge. Thus, the player can know that the winning probability has increased by the level gauge symbol x and the rising timing symbol y. The state of the winning effective value F = 3 is maintained until the symbol generation process for determining the loss is executed 33 times, and the winning determination is made by the third winning value group. In the same way, every time the number of consecutive executions K of the symbol generation process for determining the loss exceeds the reciprocal of the winning probability, the fourth winning value group and the fifth winning value group are sequentially enabled, and the level gauge symbol x and the rising timing The player is notified of the timing at which the winning probability rises according to the symbol y.

  Thus, in the configuration of the present embodiment, when the number of consecutive executions K of the symbol generation process that has been confirmed exceeds the reciprocal of the winning probability, the expectation of the player's winning by the corresponding selection probability is not satisfied, Since the winning probability increases, it is possible to stimulate the player's expectation to win. This is because if the player's expectation that the winning probability 1 / m is confirmed at a rate of once in m times of the symbol generation process is not satisfied, the winning probability is stimulated to increase the expectation of winning. Can increase willingness to play. In particular, since the level gauge symbol x and the rising timing symbol y are displayed on the image display 14, the number of consecutive executions K of the symbol generation process and the increase in the winning probability are notified, so that the expectation of the above-mentioned hit determination is expected. The effect of stimulating the feeling is further enhanced. By stimulating such a sense of expectation and increasing motivation, it is possible to suppress the impatience and irritation caused by the increase in the number of consecutive executions of the lost symbol generation process. In addition, each of the first to fifth winning value groups described above has a winning probability set to 1 or less, and the upper limit is the winning probability (= 1/20) of the fifth winning value group. That is, it is not guaranteed to be confirmed by digestion of the special start memory. Therefore, according to the present embodiment, the original playability of the pachinko game in which the determination of winning or losing is performed according to the winning probability can be maintained.

  On the other hand, in the above-described embodiment, the winning determination is performed by sequentially validating the first to fifth winning value groups having different winning probabilities, and five types of winning probabilities are set. However, it may be configured to set a plurality of different winning probabilities. For example, a configuration in which two types of winning probabilities in the first and second winning value groups are set, a configuration in which three types of winning probabilities in the first to third winning value groups are set, and the like can be adopted. Furthermore, a configuration in which six or seven types of winning probabilities are set may be used. The winning probability can also be set as appropriate.

  Further, in the above-described embodiment, when the number of consecutive executions of the symbol generation process exceeds the reciprocal of the winning probability, processing is performed so as to validate the next winning probability. If the reciprocal number is exceeded, the previous winning probability may be maintained until the symbol generation process having a predetermined number of delays is executed, and the next winning probability may be validated when the number of delays is reached. More specifically, when the number of consecutive executions K exceeds the reciprocal of the winning probability as in the starting memory digestion process of FIG. 8, 1 is added to the delay number value J every time the symbol generation process is executed. When = 10, 1 is added to the winning effective value F to make the next winning value group effective. That is, in this alternative example, even if the number of consecutive executions K exceeds the reciprocal of the winning probability, the next winning value group is not made effective immediately, and the current winning probability is maintained and 10 symbols (delay times) are generated. The process is executed, and after the 10th execution, the next winning value group is made valid. In this way, the timing at which the next winning value group (winning probability) is validated is delayed from the time when the continuous execution count K exceeds the reciprocal of the winning probability. As a result, even when the reciprocal of the winning probability includes a fractional part, the timing for validating the next winning value group is determined stably.
