Description

  The present invention relates to a gaming machine such as a pachinko machine.

A random number is acquired in response to the game ball entering the starting port, and the acquired random number is compared with the jackpot random number determined in advance at a predetermined timing. In this case, a pachinko machine that executes a jackpot game (that can acquire a large number of prize balls) advantageous to the player is known.
The result of the big hit lottery is displayed by, for example, a variable display capable of variably displaying a plurality of types of symbols at a plurality of display positions. The symbols at each display position start to change at a predetermined timing, and after a predetermined time has elapsed, stop at a predetermined order. If the result of the jackpot lottery is a jackpot, the symbol is stopped with a predetermined combination at the display position (jacket symbol). If the result of the jackpot lottery is out of place, a combination different from the jackpot symbol at the display position (outlier symbol) ) To stop the symbol.

  In this type of pachinko machine, if a jackpot with a certain probability variation among the jackpot symbols, a jackpot lottery will be held for a predetermined period after the jackpot game ends based on the jackpot (for example, until the next jackpot) In some cases, a probability variation mode (probability variation mode) is executed in which the probability that the lottery result is a jackpot (the jackpot probability) is changed to a predetermined high probability.

  If the jackpot symbol is stopped and displayed on the variable display during the probability variation mode, the probability variation mode will end, but if the jackpot is reached in the probability variation symbol, the probability variation will again change after the jackpot game based on the jackpot. The mode is to be executed (so-called continuous change). In other words, the probability variation mode is continued if the jackpot with the probability variation symbol, while the probability variation mode is terminated if the jackpot with the non-probability variation symbol (a jackpot symbol other than the probability variation symbol), and after the jackpot game based on the jackpot, Return to game mode (normal mode).

During the probability change mode, the player wins a big hit in a relatively short time thereafter, and the player is excited. Then, during the probability variation mode, the player plays a game while expecting that the probability variation mode will be continued with the jackpot with the probability variation symbol.
On the other hand, in a pachinko machine, when a game ball enters the starting port during a variable display design change or a big hit game, the variable display design change operation for that ball is put on hold. There is one that can be used (for example, see Patent Document 1). More specifically, when a game ball enters the starting port during the design change of the variable display or the big hit game, the random number acquired in response to the incoming ball is stored in the reserved random number storage unit up to a predetermined number. Remembered. And the random number memorize | stored in the pending | holding random number memory | storage part is read sequentially after the end of the symbol change of a variable display, or after the end of a big hit game, and a big hit lottery is performed using the random number.

  In a pachinko machine that can hold the variable movement of the variable display on hold, compare the random number stored in the hold random number storage with a big hit random number that is different between the normal mode and the probability change mode. There is something that is going to do a lottery lottery. In such a pachinko machine, while the random number that is a big hit during the probability change mode is stored in the pending random number storage unit, the game mode is normally changed from the probability change mode before the big hit lottery using the random number is executed. When switching to the mode, the result of the jackpot lottery using the random number is not a jackpot. In this case, the chance to win a big game is reduced, and the interest of the game is reduced.

  The present invention has been made under such a background, and an object of the present invention is to provide a gaming machine in which the interest of the game is improved.

  In order to achieve the above object, the invention according to claim 1 is a gaming machine capable of executing the probability variation mode in which the probability of winning the jackpot lottery is higher than that in the normal mode, and at a predetermined timing (for example, at the start opening). Random number acquisition means (30, 31) for acquiring random numbers (when a game ball enters), random number storage means (32) for storing up to a predetermined number of random numbers acquired by the random number acquisition means, and The jackpot lottery execution means (30, S2, S3, T6, T7) for performing the jackpot lottery different in the normal mode and the probability variation mode by sequentially reading the random numbers stored in the random number storage means and comparing with a predetermined jackpot random number. ) And a jackpot game that executes a jackpot game advantageous to the player when the random number read from the random number storage means at the time of the jackpot lottery matches the jackpot random number A probability variation mode for executing the probability variation mode only for a predetermined period when the random number read from the random number storage means at the time of the jackpot lottery coincides with a specific probability variation random number among the jackpot random numbers, the row means (30, S8, T12) Among the random numbers stored in the random number storage means when the probability variation mode ends, the execution unit (30, S11), and a specific jackpot random number that is a jackpot random number in the probability variation mode but is not a jackpot random number in the normal mode, It is a gaming machine characterized by including specific jackpot random number storage means (33) for storing at a predetermined probability for use in a jackpot lottery in the subsequent probability variation mode.

The alphanumeric characters in parentheses indicate corresponding components in the embodiments described later. The same applies hereinafter.
According to this configuration, the specific jackpot random number storage means that is not used in the jackpot lottery during the probability variation mode is stored in the jackpot lottery during the probability variation mode (for example, in the next probability variation mode) performed thereafter. Can be a lottery lottery. Therefore, even though a random number that is a big hit is acquired during the probability variation mode, the game mode is switched from the probability variation mode to the normal mode before the big hit lottery using that random number is executed. It is possible to prevent a situation in which the result of the jackpot lottery using random numbers does not become a jackpot and the chances of winning the jackpot decrease. As a result, the probability of winning a jackpot during the probability variation mode can be increased, so that the player's expectation for becoming a continuous player can be increased, and the interest of the game is improved.

The predetermined probability may be 100%.
The probability variation mode execution means (30, S11) ends the probability variation mode when the random number read from the random number storage means (32) at the time of the jackpot lottery matches the jackpot random number other than the probability variation random number (T16). It may be a thing.
As in the invention described in claim 2, the jackpot lottery executing means (30, S2, S3, T6, T7) is configured when a predetermined condition is satisfied during the probability variation mode (for example, the result of the jackpot lottery is a predetermined number of times). If the player wins only a big win or wins a predetermined lottery, etc., the special big hit random number stored in the specific big hit random number storage means (33) may be read to perform the big hit lottery. .

  According to the third aspect of the present invention, there is provided random number storage lottery execution means (30, P4, P5) for performing random number storage lottery for determining whether or not to store a specific jackpot random number in the specific jackpot random number storage means (33). 3. The gaming machine according to claim 1, wherein the random number storage lottery has different probabilities of winning depending on whether or not the specific jackpot random number to be stored in the specific jackpot random number storage means is a probability varying random number. It is.

According to this configuration, the probability that the specific jackpot random number to be stored in the specific jackpot random number storage means differs depending on whether or not the specific jackpot random number to be stored in the specific jackpot random number storage means is a probability variation random number. It is possible to change the probability that the mode will continue (probability of consecutive Chang), and the fun of the game will be improved.
In particular, when the specific jackpot random number to be stored in the specific jackpot random number storage means is a probability variation random number, if the random number storage lottery is elected with a relatively high probability, the probability of becoming a continuous chain is increased. Since it is possible, the interest of the game can be further improved.

Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a front view showing a configuration of a pachinko machine according to an embodiment of the present invention.
Referring to FIG. 1, this pachinko machine includes a game board 1, a handle 2 for adjusting the momentum of a game ball launched from a launcher (not shown) toward the game board 1, and a game from the launcher. An upper plate 3 for storing game balls to be launched toward the board 1 and a lower plate 4 for receiving game balls that cannot be stored in the upper plate 3 are provided.

  On the periphery of the game board 1, a substantially arc-shaped guide rail 11 for guiding the game ball launched from the launch device to the upper left side of the game board 1 is disposed. A large number of obstacle nails (not shown) are arranged on the game board 1, and the game balls released along the guide rail 11 from the upper left side of the game board 1 diagonally upward to the right are the game board 1. Along the board surface, it falls through a number of obstacle nails.

  A variable display 12 is disposed at the approximate center of the game board 1. The variable display 12 is constituted by, for example, a liquid crystal display, and three display positions (left display position 12L, center display position 12C, right display position) arranged side by side in the horizontal direction are displayed on the display screen. 12R), a plurality of types of symbols (for example, numbers “1” to “9”) can be displayed in a variable manner. The variable display device 12 can display a combination of three symbols by stopping one of the plural types of symbols at the three display positions 12L to 12R.

  Below the variable display 12, a start port 13 into which a game ball falling along the board surface of the game board 1 can enter is arranged. When a game ball enters the start port 13, a predetermined number of award balls (game balls) are paid out to the upper plate 3 by a prize ball payout device (not shown) and are advantageous to the player (multiple prizes). A random number used in the jackpot lottery for determining whether or not to execute the jackpot game (which can acquire a ball) is acquired. A jackpot lottery is performed by comparing the acquired random number with a jackpot random number determined in advance at a predetermined timing. If the acquired random number matches the jackpot random number, the jackpot is won, and the acquired random number does not match the jackpot random number. In this case, it will be out of place.

  In this embodiment, the random number acquired for the ball entering the start port 13 is temporarily stored in the hold random number storage unit 32 (see FIG. 2). The reserved random number storage unit 32 can store up to a predetermined number of random numbers. When a game ball enters the start port 13 in a state in which no random number is stored in the hold random number storage unit 32 when the variable indicator 12 is not changing a symbol or playing a big hit game, in response to the incoming ball The random number stored in the hold random number storage unit 32 is immediately read out, and a big hit lottery is performed using the random number. On the other hand, when a game ball enters the start port 13 while the variable indicator 12 is changing the design or during the big hit game, the random number stored in the hold random number storage unit 32 in response to the incoming ball is stored in the variable indicator. It is sequentially read out after the end of the twelve symbol changes and after the end of the jackpot game, and the jackpot lottery is performed using the random numbers.

  The result of the big hit lottery is displayed on the variable display 12. The symbols of the three display positions 12L to 12R start to fluctuate every time a random number is read from the reserved random number storage unit 32, and after a predetermined time has elapsed, for example, the left display position 12L, the right In the order of the display position 12R and the central display position 12C). The result of the big hit lottery is displayed by a combination of symbols finally stopped at the three display positions 12L to 12R. That is, if the jackpot lottery result is a jackpot, the symbols are finally stopped at all three display positions 12L to 12R with the same symbol combination (jackpot symbol). On the other hand, if the result of the big hit lottery is out of place, the symbols are finally stopped at the three display positions 12L to 12R with a combination (out of symbol) different from the big hit symbol. The combination of symbols to be finally stopped at the three display positions 12L to 12R is determined by stop symbol drawing.

  When the probability variation pattern (for example, “111”, “333”, “555”, “777”, “999”) finally stops at the three display positions 12L to 12R, the jackpot game based on the jackpot ends. The probability variation mode (probability variation mode) in which the probability that the result of the jackpot lottery will be a big hit (big hit probability) is changed to a predetermined high probability only for a later predetermined period (for example, until the next big win). Specifically, the jackpot probability that was 1/315 in the normal game mode (normal mode) is 1/60 in the probability variation mode.

  When the jackpot symbol stops at the three display positions 12L to 12R in the probability variation mode, the probability variation mode ends. However, if the jackpot symbol is a jackpot in the probability variation symbol, the jackpot game based on the jackpot is finished, and then again. Probability mode is executed (so-called continuous change). That is, the probability variation mode is continued if the probability variation symbol is a jackpot (probability variation jackpot), while the non-probability variation symbol (for example, “222”, “444”, “666”, “888”) is a jackpot (ordinary bonus). If this is the case, the probability variation mode ends, and after the jackpot game based on the jackpot, the normal mode is restored.

  Below the start opening 13, for example, a large winning opening 14 that is formed in a rectangular shape that is long to the left and right and that allows a plurality of game balls to enter simultaneously is disposed. In relation to the big prize opening 14, there is provided an opening / closing plate 15 that can be opened and closed in an open state in which a game ball is guided to the big prize opening 14 and in a closed state that prevents the game ball from entering the big prize opening 14. . That is, the open / close plate 15 closes the grand prize opening 14 in a state along the board surface of the game board 1 and can prevent a game ball from entering the big prize opening 14. A game ball that falls on the grand prize winning opening 14 by opening the grand prize winning opening 14 by lying down on the front side around a pivot shaft (not shown) arranged along the lower edge of the figure 14. Can be introduced into the grand prize opening 14.

  In the jackpot game, an operation in which the opening and closing plate 15 is opened for a predetermined time or until a predetermined number of game balls enter the grand prize winning opening 14 is defined as one round. If at least one of them passes through a special area (so-called V zone) in the big prize opening 14, the opening operation of the big prize opening 14 by the opening / closing plate 15 is performed in a predetermined round, such as executing the next round. Only done. A predetermined number of prize balls are paid out to the upper plate 3 for entering the game balls into the big prize opening 14. In the jackpot game, the game ball easily enters the big prize opening 14, so that the player can obtain a large number of prize balls.

The game balls (out balls) that have not entered the start opening 13 and the big winning opening 14 are collected in the machine from the out ball collection opening 16 formed in the lower part of the game board 1.
FIG. 2 is a block diagram showing an electrical configuration of the pachinko machine.
Referring to FIG. 2, the operation of this pachinko machine is controlled by a control unit 30 including a microcomputer. The control unit 30 includes a random number generation unit 31 for generating a random number used in the jackpot lottery, a hold random number storage unit 32 capable of storing up to a predetermined number of random numbers acquired from the random number generation unit 31, and a hold random number storage unit 32. Among the stored random numbers, a specific jackpot random number storage unit 33 for storing (stocking) a specific jackpot random number (specific jackpot random number), and a specific jackpot random number stored in the specific jackpot random number storage unit 33 are set to a predetermined number A counter 34 that performs counting in order to read at timing is functionally provided.

  The control unit 30 includes a start port sensor 131 that detects a game ball that enters the start port 13 and outputs a signal, and a grand prize port sensor 141 that detects a game ball that enters the grand prize port 14 and outputs a signal. Connected so that output signals from the start port sensor 131 and the big prize winning port sensor 141 are input to the control unit 30. On the other hand, the variable display 12 and the opening / closing plate 15 are connected to the control unit 30 as control targets. The control unit 30 is based on detection signals from the start port sensor 131 and the big prize port sensor 141, and the like. The operation of these controlled objects is controlled.

  FIG. 3 is a time chart showing the flow of a game when a specific jackpot random number is stocked in the specific jackpot random number storage unit 33. FIG. 4 is a conceptual diagram for explaining an aspect when stocking a specific jackpot random number in the specific jackpot random number storage unit 33. In the example of FIG. 4, up to 10 random numbers can be stored in the hold random number storage unit 32 and the specific jackpot random number storage unit 33, respectively.

  When the probability change jackpot is won during the normal mode (see FIG. 3A), the jackpot game for the jackpot is executed (see FIG. 3B), and then the probability change mode is executed (FIG. 3C). reference). When a game ball enters the start port 13 during the jackpot game, the random numbers acquired from the random number generation unit 31 are sequentially stored in the reserved random number storage unit 32. When the probability change mode is started after the jackpot game ends, random numbers are read in the order stored from the reserved random number storage unit 32, and the jackpot lottery is performed using the random numbers.

  FIG. 4A shows a state in which the random numbers stored in the hold random number storage unit 32 are five as a result of sequentially reading random numbers from the hold random number storage unit 32 during the probability variation mode. In this example, “7” and “177” of the random numbers stored in the reserved random number storage unit 32 are jackpot random numbers (in FIG. 4, areas where the jackpot random numbers of the reserved random number storage unit 32 are stored) Are hatched.) When the big hit lottery is performed from the state of FIG. 4A, the random number “7” stored in the hold random number storage unit 32 is read. When the random number “7” is a random number corresponding to a normal jackpot, the result of the jackpot lottery using this random number is a normal jackpot, and the probability variation mode ends (see FIG. 3D). At this time, as shown in FIG. 4B, the remaining four random numbers stored in the hold random number storage unit 32 are used for the big hit lottery in the subsequent normal mode (see FIG. 3G). .

  In this embodiment, the random numbers stored in the hold random number storage unit 32 are different jackpot random numbers in the normal mode and the probability variation mode (all of the jackpot random numbers may be different, or some of them are different (some A lottery lottery is performed by comparing with (a duplication). Accordingly, when a big hit lottery is performed using the random number “177” during the probability variation mode, a big hit is made, but even if the big hit lottery is performed using the random number “177” during the normal mode, no big win is obtained. In other words, the game mode is changed from the probability change mode to the normal mode before the jackpot lottery using the random number is executed even though the random number “177” which is a jackpot is stored in the pending random number storage unit 32 during the probability change mode. In the case of switching to, the result of the jackpot lottery using the random number is not a jackpot, and the chance of winning the jackpot is reduced.

  Therefore, in this embodiment, as shown in FIG. 4C, the random number stored in the pending random number storage unit 32 at the time when the game mode is switched from the probability change mode to the normal mode (when the probability change mode ends). Of these, random numbers (specific jackpot random numbers) that are jackpots in the probability variation mode but not jackpots in the normal mode can be stored in the specified jackpot random number storage unit 33 (stock processing; FIG. 3 (e) )reference).

  Thereafter, after the jackpot game for the normal jackpot is executed (see FIG. 3 (f)), the game mode returns to the normal mode (see FIG. 3 (g)), and when the probability change jackpot is again (see FIG. 3 (h)). After the jackpot game for the jackpot is executed (see FIG. 3 (i)), the probability variation mode is executed (see FIG. 3 (j)). At this time, the specific jackpot random number stocked in the specific jackpot random number storage unit 33 is read at a predetermined timing, and the jackpot lottery is performed using the specific jackpot random number (see FIG. 3 (k)).

  According to such a configuration, the specific jackpot random number that was not used for the jackpot lottery during the probability variation mode can be read out from the specific jackpot random number storage unit 33 during the next probability variation mode and the jackpot lottery can be performed. Therefore, even though a random number that is a jackpot is acquired during the probability change mode, the game mode is switched from the probability change mode to the normal mode before the jackpot lottery using that random number is executed. It is possible to prevent a situation in which the result of the used jackpot lottery does not result in a jackpot and the chance of winning a jackpot decreases. As a result, the probability of winning a jackpot during the probability variation mode can be increased, so that the player's expectation for becoming a continuous player can be increased, and the interest of the game is improved.

FIG. 5 is a flowchart showing a control flow of the control unit 30 in the normal mode.
Referring to FIG. 5, during the normal mode, when the variable display 12 fluctuates (when the variable display 12 is not changing the symbol or the jackpot game is being played, the starting random number is not stored in the on-hold random number storage unit 32. When a game ball enters 13, when a game ball enters the start port 13, when a random number is stored in the hold random number storage unit 32, the variable display 12 corresponding to the previously stored random number is stored. When the symbol variation ends (YES in step S1), the control unit 30 reads random numbers according to the order stored from the reserved random number storage unit 32 (step S2), performs a big hit lottery (step S3), and stops. A symbol lottery is performed (step S4). Then, the control part 30 starts the symbol fluctuation | variation of the variable indicator 12 (step S5). If the result of the big hit lottery is out of place (NO in step S6), the control unit 30 stops the out-of-design at the three display positions 12L to 12R after a predetermined time has elapsed (step S12), and continues in the normal mode. Execute.

  When the jackpot lottery result is a jackpot (YES in step S6), the control unit 30 stops the jackpot symbol at the three display positions 12L to 12R after a predetermined time has elapsed (step S7), and executes the jackpot game ( Step S8). After the jackpot game is over, the control unit 30 sets “100” to the counter 34 (step S9), and when the jackpot lottery result is a winning jackpot (YES in step S10), the probability changing mode is started (step S11). ). On the other hand, when the result of the big hit lottery is not a promising big hit, that is, when the big hit is normal (NO in step S10), the control unit 30 executes the normal mode as it is.

FIG. 6 is a flowchart showing a control flow of the control unit 30 in the probability variation mode.
Referring to FIG. 6, during the probability change mode, the timing of change of variable display 12 (starting port in a state where random numbers are not stored in reserved random number storage unit 32 when variable display 12 is not changing symbols or playing big hit games) When a game ball enters 13, when a game ball enters the start port 13, when a random number is stored in the hold random number storage unit 32, the variable display 12 corresponding to the previously stored random number is stored. When the symbol variation has ended (YES in step T1), the control unit 30 decrements the count value of the counter 34 by -1 (step T2), and then determines whether or not the count value of the counter 34 is “0”. (Step T3).

  Since “100” is set in the counter 34 at the time when the probability variation is a big hit, the count value of the counter 34 is “0” from the time the probability variation mode starts until the symbol change of the variable display 12 is performed 100 times. Instead (NO in step T3), the control unit 30 reads random numbers according to the order stored from the reserved random number storage unit 32 (step T6), and performs a lottery lottery using the random numbers (step T7).

  When the variation of the symbol of the variable indicator 12 is performed 100 times from the start of the probability variation mode and the count value of the counter 34 becomes “0” (YES in Step T3), the control unit 30 stores the specific jackpot random number storage unit 33 in the specified jackpot. It is determined whether or not random numbers are stocked (step T4). When the specific jackpot random number storage unit 33 stores the specific jackpot random number (YES in step T4), the control unit 30 reads the specific jackpot random number according to the order stored from the specific jackpot random number storage unit 33 ( Step T5), the big hit lottery is performed using the random number (step T7). The result of this jackpot lottery will always be a jackpot.

On the other hand, when the specific jackpot random number is not stocked in the specific jackpot random number storage unit 33 (NO in step T4), the control unit 30 reads the random numbers in the order stored from the reserved random number storage unit 32 (step T6). Then, the big hit lottery is performed using the random number (step T7).
After performing the big hit lottery, the control unit 30 performs the stop symbol lottery (step T8) and starts the symbol variation of the variable display 12 (step T9). When the result of the big hit lottery is out of place (NO in step T10), the control unit 30 stops the symbols in the three display positions 12L to 12R after a predetermined time has elapsed (step T17), and the probability change mode is continued. Execute.

  When the jackpot lottery result is a jackpot (YES in step T10), the control unit 30 stops the jackpot symbol at the three display positions 12L to 12R after a predetermined time has elapsed (step T11), and executes the jackpot game ( Step T12). After the jackpot game ends, the control unit 30 sets “100” in the counter 34 (step T13). And when the result of the jackpot lottery is not a promising big hit, that is, when it is a normal big hit (NO in step T14), the control unit 30 ends the probability changing mode after performing the stock processing (step T15), The game mode is switched to the normal mode (step T16). On the other hand, when the result of the jackpot lottery is a probability variation jackpot (YES in step T14), the control unit 30 executes the probability variation mode as it is.

FIG. 7 is a flowchart showing a control flow of the control unit 30 during stock processing.
Referring to FIG. 7, when the stock process is started, first, control unit 30 sequentially checks whether or not the random number stored in pending random number storage unit 32 is a specific jackpot random number according to the stored order. (Step E1). If the checked random number is a specific jackpot random number (YES in step E2), the control unit 30 stocks the random number in the specific jackpot random number storage unit 33 (step E3). On the other hand, if the checked random number is not the specific jackpot random number (NO in step E2), the control unit 30 stores the random number in the reserved random number storage unit 32 without stocking the random number in the specific jackpot random number storage unit 33. Check whether the next random number is a specific jackpot random number.

In this way, the control unit 30 checks whether or not all random numbers stored in the pending random number storage unit 32 are specific jackpot random numbers, and when all random numbers have been checked (in step E4). YES), stock processing ends.
FIG. 8 is a flowchart showing a control flow of the control unit 30 during stock processing according to a modification of this embodiment.

  Referring to FIG. 8, in this modification, when the stock process is started, first, control unit 30 stores whether or not the random number stored in reserved random number storage unit 32 is a specific jackpot random number. Are sequentially checked in accordance with the order (step P1). If the checked random number is not a specific jackpot random number (NO in step P2), the control unit 30 stores the random number in the reserved random number storage unit 32 without stocking the random number in the specific jackpot random number storage unit 33. Check whether the next random number is a specific jackpot random number.

  If the checked random number is a specific jackpot random number (YES in step P2), the control unit 30 determines whether or not the random number is a probable random number (a random number that will be a promiscuous jackpot when the big hit lottery is performed). (Step P3). In this modification, the specific jackpot random numbers stored in the reserved random number storage unit 32 are not stocked in the specific jackpot random number storage unit 33 as in the above embodiment, but are stored in the reserved random number storage unit 32. A lottery with a different winning probability (high probability stock lottery or low probability stock lottery) is performed depending on whether the jackpot random number is a probabilistic random number, and the specific jackpot random number is stored only when the lottery is won. The configuration is such that it is stored in the unit 33. That is, when the specific jackpot random number stored in the reserved random number storage unit 32 is a probability variable random number (YES in Step P3), the control unit 30 executes a high probability stock winning lottery that wins with a relatively high probability. On the other hand (step P4), if the specific jackpot random number stored in the pending random number storage unit 32 is not a probability random number (NO in step P3), a low-probability stock winning lottery that wins with a relatively low probability is executed (step S3). P5).

  When the high-probability stock winning lottery or the low-probability stock winning lottery is won (YES in Step P6), the control unit 30 stocks the random number in the specific jackpot random number storage unit 33 (Step P7). On the other hand, when the high-probability stock winning lottery or the low-probability stock winning lottery is not won (NO in Step P6), the control unit 30 does not store the random number in the specific jackpot random number storage unit 33, but holds the random number. It is checked whether or not the next random number stored in the storage unit 32 is a specific jackpot random number.

In this way, the control unit 30 checks whether or not all random numbers stored in the pending random number storage unit 32 are specific jackpot random numbers, and when all random numbers have been checked (in step P8). YES), stock processing ends.
As in this modification, a lottery with different winning probabilities is performed depending on whether or not the specific jackpot random number stored in the pending random number storage unit 32 is a probability variable random number, and only when the lottery is won, the specific jackpot random number Is stored in the specific jackpot random number storage unit 33, the probability that the probability variation mode is continued (probability of continuous change) can be changed, so that the interest of the game is improved.

In particular, when the specific jackpot random number stored in the pending random number storage unit 32 is a probabilistic random number, a high probability stock winning lottery that wins with a relatively high probability is executed, thereby becoming a continuous chain. Since the probability can be increased, the interest of the game can be further improved.
However, the probability of winning is not limited to a configuration in which a lottery with different winning probabilities is performed depending on whether or not the specific jackpot random number stored in the hold random number storage unit 32 is a probabilistic random number. May be configured to perform the same lottery.

The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.
For example, the specific jackpot random number stored in the specific jackpot random number storage unit 33 may not be read during the next probability variation mode, but may be read during the probability variation mode after a predetermined number of times.

The configuration is not limited to a configuration in which the specific jackpot random number is read from the specific jackpot random number storage unit 33 based on the count value of the counter 34.
