Hereinafter, an embodiment of a pachinko gaming machine will be described.
As shown in FIG. 1, a pachinko gaming machine as a gaming machine is provided with a gaming board YB. On the front side of the pachinko gaming machine, a launch handle HD that is operated by the player when launching a game ball onto the game board YB is disposed. In the center of the game board YB, an effect display device 10 having an image display unit GH is disposed. The image display unit GH of the effect display device 10 is, for example, a liquid crystal display type display unit.

  In addition, a special symbol display device 11 composed of a plurality of light emitting units is disposed on the lower right side of the effect display device 10 in the game board YB. In the special symbol display device 11, a changing game is performed by changing the special symbol. In the following description, a variation game using a special symbol is referred to as a “special symbol variation game”. The special symbol is a notification symbol indicating a result of an internal determination (whether to be described later) whether or not the game is a hit. In addition, the hit determination of this embodiment can also be grasped as a win lottery for determining whether or not a win. Further, the hit determination of the present embodiment includes a big hit determination (big hit lottery) as to whether or not a big hit and a small hit determination (small hit lottery) as to whether or not a small hit.

  The special symbol display device 11 displays a special symbol by turning on and off the light emitting unit. In the special symbol display device 11, the special symbol variation display is started simultaneously with the start of the special symbol variation game, and the special symbol is fixedly stopped and displayed simultaneously with the end of the special symbol variation game. The “variable display” is a state in which the type of the displayed symbol is changed in the display area defined in the display device that displays the symbol. The “deterministic stop display” is a state in which the symbols are fixed and stopped in the display area, and is a state in which the symbols are determined and stopped at the end of the variable game.

  In the special symbol variation game of the present embodiment, a special symbol selected from a plurality of types of special symbols is displayed as a fixed stop display as a display result corresponding to the determination result of the hit determination. Special symbols are classified into jackpot symbols that can recognize jackpots (big hit display results), jackpot symbols that can recognize jackpots (small hits display results), and detachable symbols that can recognize gaps (missed display results). Is done. In the following description, the big hit symbol and the small hit symbol may be collectively shown as a hit symbol (hit display result).

  On the other hand, in the effect display device 10, a display effect is performed as a game effect in association with the special symbol variation game. Specifically, in the effect display device 10, as one of the display effects, there is a variable game in which a plurality of types of decorative symbols are changed in a plurality of symbol rows (three rows in the present embodiment) and a symbol combination is displayed (derived). Done. In the following description, a variation game using a decorative symbol is referred to as a “decorative symbol variable game”. The decorative design is a design for production (production design) used for diversifying display production. The decorative design is displayed as an image imitating seven types of Arabic numerals 1 to 7, for example.

  In the effect display device 10, the decorative symbol variation display is started simultaneously with the start of the special symbol variation game. Further, in the effect display device 10, the decorative symbols are temporarily stopped before the end of the special symbol variation game, and the decorative symbols are fixedly stopped and displayed simultaneously with the end of the special symbol variation game. “Temporary stop display” is a state indicating that there is a possibility that the symbol may be variably displayed again in the display area, such as a fluctuation state.

  The effect display device 10 is configured with a display area larger than that of the special symbol display device 11, and the decorative symbol is displayed much larger than the special symbol. For this reason, the player can recognize the big hit, the small hit or the loss from the symbol combination exclusively displayed on the effect display device 10.

  The effect display device 10 displays a display result corresponding to the display result of the special symbol variation game. More specifically, when the big hit symbol (big hit display result) is confirmed and stopped in the special symbol variation game, the big hit symbol (big hit display result) is also confirmed and stopped on the effect display device 10. In the present embodiment, the big hit symbol based on the decorative symbol is a symbol combination in which the decorative symbols of all the rows that are confirmed and stopped on the effect display device 10 are the same. Further, when the small hit symbol (small hit display result) is confirmed and stopped in the special symbol variation game, the small hit symbol (small hit display result) is also confirmed and stopped on the effect display device 10. In the present embodiment, the small hit symbol based on the decorative symbol is a symbol combination in which the decorative symbols of all the rows that are confirmed and stopped displayed on the effect display device 10 are a predetermined combination.

  Further, in the special symbol variation game, when the deviation symbol (outlier display result) is confirmed and stopped, the loss symbol (outlier display result) is also confirmed and stopped on the effect display device 10. In the present embodiment, the out-of-decoration symbol based on the ornament symbol is a symbol combination in which all the ornament symbols that are confirmed and stopped displayed on the effect display device 10 are not the same, and is a symbol combination other than the small hit symbol combination due to the ornament symbol. ing.

  In the decorative symbol variation game of the present embodiment, the decorative symbols are temporarily stopped in the order of left column (left symbol) → right column (right symbol) → middle column (middle symbol) as seen from the player side in the effect display device 10. Is displayed. When the left symbol and the right symbol that are once stopped and displayed are the same, the reach state can be recognized from the symbol combination (such as “1 ↓ 1”, where “↓” indicates a change). In the reach state, the decorative symbols in the specific columns (the left column and the right column in the present embodiment) are temporarily stopped among all the symbol columns, and are temporarily displayed, and the columns other than the specific columns (the middle column in the present embodiment) ) Is displayed in a variable manner. In the present embodiment, the symbol combination that can recognize the reach state is the symbol combination of the reach by the decorative symbol.

  Further, in the effect display device 10 of the present embodiment, the reach is one of the display effects after the reach symbol combination is formed in the decorative symbol variation game until the symbol combination is finally stopped and displayed. Production can be performed. The reach effects of the present embodiment include a normal reach effect and a super reach effect that is performed by developing the effect of the normal reach effect during the variable display of the decorative pattern in the middle row.

  In the game board YB, below the effect display device 10, a start port 12 having a entrance into which a game ball can enter is disposed. Further, a start sensor SE (shown in FIG. 3) for detecting a game ball that has entered the entrance is provided in the back of the start entrance 12. The start sensor SE can give a start condition for the special symbol variation game triggered by detecting a game ball that has entered the entrance of the start port 12. In addition, the start sensor SE gives a predetermined condition for paying out game balls as a predetermined number of prize balls when the game balls that have entered the entrance of the start port 12 are detected.

  Further, the start port 12 has an opening / closing blade (ordinary electric accessory) 12a that opens and closes by an operation of an ordinary electric accessory solenoid SOL1 (shown in FIG. 3). The opening / closing blade 12a can be operated in an open state in which a game ball can easily enter the entrance port of the start port 12 and in a closed state in which it is difficult for the game ball to enter the entrance port of the start port 12. The opening / closing blade 12a is always controlled to be in a closed state, and when a predetermined opening condition is satisfied, the opening / closing blade 12a is controlled to be in an open state for a predetermined opening time only once or a plurality of times.

  In the game board YB, below the start opening 12, a large winning opening 13 having a large winning opening door 13a that is opened and closed by an operation of a large winning solenoid SOL2 (shown in FIG. 3) is disposed. Further, a count sensor CS (shown in FIG. 3) that detects a game ball that has entered the big prize opening 13 is provided in the back of the big prize opening 13. The count sensor CS gives a predetermined condition of paying out game balls as a predetermined number of award balls when it detects a game ball that has entered the special winning opening 13.

  In the pachinko gaming machine according to the present embodiment, a positive determination is made in the winning determination, and the winning game is awarded after the winning symbol (winning display result) is displayed in a definite stop state in the special symbol variation game. In the winning game, the grand prize opening door 13a is opened, and the game balls are allowed to enter the big prize opening 13. For this reason, during the winning game, the player can obtain a chance to acquire the winning ball payout condition.

  On the game board YB, a hold display device 14 composed of a plurality of light emitting units is disposed on the lower right side of the effect display device 10. The hold display device 14 displays the number of on-hold special symbol variation games to which start conditions have been given but have not yet been executed. In the following description, the number of special symbol variation games on hold is indicated as “special symbol hold number”.

  In the game board YB, a normal symbol display device 15 composed of a plurality of light emitting units is disposed on the lower right side of the effect display device 10. In the normal symbol display device 15, a change game is executed by changing the normal symbol. In the following description, a variation game using a normal symbol is referred to as “ordinary symbol variation game”. The normal symbol is a notification symbol indicating the result of internal determination (normal hit determination) as to whether or not the normal hit. The normal symbol display device 15 displays the normal symbol by turning on and off the light emitting unit. In the normal symbol display device 15, the normal symbol variation display is started simultaneously with the start of the normal symbol variation game, and the normal symbol is fixedly stopped and displayed simultaneously with the end of the normal symbol variation game.

  In the normal symbol variation game of the present embodiment, the normal symbol is displayed as a fixed stop as a display result corresponding to the determination result of the normal hit determination. The normal symbol is classified into a normal hit symbol that can recognize a normal hit (ordinary hit display result) and a normal offset symbol that can recognize a normal offset (usually a shift indication result).

  In the pachinko gaming machine according to the present embodiment, an affirmative determination is made in the normal winning determination, and the normal winning game is awarded after the normal winning symbol is confirmed and stopped in the normal symbol changing game. In the normal hit game, the opening / closing blade 12a is in an open state, and it becomes easy to enter the game ball into the entrance of the start port 12. For this reason, during a normal game, the player can have a chance to easily acquire the start condition of the special symbol variation game and the payout condition of the prize ball.

  An operation gate 16 is disposed on the left side of the effect display device 10 in the game board YB. The operation gate 16 is provided with a gate sensor GS (shown in FIG. 3) that detects a game ball that has entered (passed). The gate sensor GS of the operation gate 16 can give the start condition of the normal symbol variation game triggered by detecting the game ball that has entered the operation gate 16. Note that the pachinko gaming machine according to the present embodiment is configured such that the execution of the normal symbol variation game can be suspended. In the following description, the number of held normal symbol variation games that have been given start conditions but have not yet been executed will be referred to as “ordinary symbol hold number”.

  Further, the pachinko gaming machine according to the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function. The probability variation function is a function that gives a probability variation state in which the probability (hit probability) of affirmatively determining jackpot determination is changed from a low probability to a high probability after the end of the jackpot game. In the probability variation state, compared to a state where the probability variation state is not given (hereinafter referred to as “non-probability variation state”), the probability of affirmatively determining the big hit determination is changed to a high probability and the big hit game is easily given. This can be an advantageous situation for the player.

  Further, the pachinko gaming machine of the present embodiment has a function of shortening the variation time (hereinafter referred to as “variation”). The variable speed function is a function for giving a variable speed state advantageous to the player after the big hit game is finished. In the variable state, the variation time of the normal symbol variation game is shortened compared to a state where the variable state is not given (hereinafter referred to as “non-variable state”). Further, in the variable state, the probability that the normal hit determination is positive (ordinary hit probability) is higher than that in the non-variable state. In the variable state, when the normal hit determination is affirmatively determined, the opening time of the opening / closing blade 12a based on the positive determination of one normal hit determination is longer than that in the non-variable state. As compared with the non-variable state, the variable speed state is a state where the entrance rate of the start port 12 to the entrance is improved per unit time. Also, in the variable state, the variation time of the special symbol variation game may be shortened compared to the non-variable state. There is a case. In the following description, a gaming state that is in a non-probable change state and in a non-change state is simply referred to as a “normal state”.

Next, the winning in this embodiment will be described.
In this embodiment, when an affirmative determination is made in the hit determination, one hit is determined from a plurality of types (four types in the present embodiment), and a hit game based on the determined hit is given. Which of the multiple types of winning is determined is specified by the type of special symbol (winning symbol) selected (determined) when a positive determination is made in the winning determination. The hit game of the present embodiment includes a big hit game based on the big hit symbol and a small hit game based on the small hit symbol. Specifically, in the present embodiment, the type of jackpot game is specified based on the type of special symbol selected as the jackpot symbol when the affirmative determination is made in the jackpot determination (that is, the type of jackpot). Further, in the present embodiment, the type of the small hit game is specified based on the type of the special symbol (ie, the type of the small hit) selected as the small hit symbol when an affirmative determination is made in the small hit determination.

  The big hit game is started after the end of the special symbol variation game in which the big hit symbol is confirmed and stopped. When the big hit game is started, an opening effect indicating the start of the big hit game is first performed. After the opening effect is completed, a round game in which the grand prize opening door 13a (large prize winning opening 13) is opened is performed a predetermined number of times up to a predetermined number of rounds. During one round game, the grand prize opening door 13a is in a period until either the first end condition for entering the upper limit number of game balls to enter or the second end condition for which the specified time elapses is satisfied. Opened. In round games, round effects are performed. When all the round games are finished, an ending effect indicating the end of the jackpot game is performed, and the jackpot game is finished.

  The small hit game is started after the end of the special symbol variation game in which the small hit symbol is confirmed and stopped. In the small hit game, the special prize opening door 13a (large prize opening door 13) is opened a predetermined number of times. In the small hit game, the grand prize winning door 13a is opened until either the first end condition for entering the upper limit number of game balls to enter or the second end condition for which the specified time elapses is satisfied. The In addition, the small hit game is terminated when a predetermined number of opening operations are completed.

  As shown in FIG. 2, in the pachinko gaming machine according to the present embodiment, as the types of jackpots, the jackpot ZA determined by selection of the jackpot symbol classified as the special symbol ZA and the jackpot symbol classified as the special symbol ZB. A jackpot ZB determined by selection is prepared. Further, in the pachinko gaming machine of the present embodiment, as the types of small hits, selection of the small hit ZC determined by the selection of the small hit symbols classified as the special symbol ZC and the selection of the small hit symbols classified as the special symbol ZD And a small hit ZD determined by.

  In the big hit game based on the big hit ZA, “15 times” is set as the prescribed number of rounds, and the probable change state and the variable state are given from the end of the big hit game until the next big hit game is given. The On the other hand, in the big hit game based on the big hit ZB, “15 times” is set as the prescribed number of rounds. In the jackpot game based on the jackpot ZB, the probability variation state is not given, and after the jackpot game is over until the special symbol variation game of the predetermined number of operations (100 times in the present embodiment) is ended, or The variable state is given until the next jackpot game is given before the end of the special symbol fluctuation game of the number of times of operation. Further, in this embodiment, in any jackpot game, “25 seconds” is set as the prescribed time of the round game, and “10” is set as the upper limit number of entering balls.

  In the small hit game based on the small hit ZC and the small hit game based on the small hit ZD, the big winning opening door 13a is opened once. In addition, in the small hit game based on the small hit ZC and the small hit game based on the small hit ZD, “10 pieces” is set as the upper limit number of entering balls. In addition, in the small hit game based on the small hit ZC, “2 seconds” is set as the specified time for opening the big prize opening door 13a. On the other hand, in the small hit game based on the small hit ZD, “0.5 seconds” is set as the specified time for the big winning opening door 13a to be opened.

  Further, in the small hit game, the game state after the small hit game is continued in the game state when the positive determination is made in the small hit determination. In other words, in the small hit game, if the positive change state is given when the small hit determination is affirmative, the positive change state is continuously given even after the small hit game ends, and when the positive determination is made in the small hit determination If the change state is given to the game, the change state is continuously given even after the end of the small hit game. In the small hit game, if the game state when the affirmative determination is made in the small hit determination is the normal state, the normal state is continued even after the small hit game is finished.

  Next, various game effects that can be executed during the execution of the special symbol variation game in the pachinko gaming machine of the present embodiment will be described. In the following description, the degree of expectation that the determination result of the big hit determination is affirmative is simply referred to as “big hit expected degree”.

  In the present embodiment, as one of the game effects, during the execution of one special symbol variation game, the decorative symbol variation display is started and then the decorative symbol is temporarily stopped to display the symbol symbol combination. It is possible to execute a quasi-continuous effect that sequentially executes a variable cycle of up to one time over a plurality of times (up to four times in the present embodiment). In other words, the quasi-continuous effect of the present embodiment is a game effect in which the decorative symbol variation display is executed a plurality of times during one special symbol variation game. In the pseudo-continuous production of the present embodiment, the expectation of big hit increases as the number of fluctuation cycles executed in one special symbol fluctuation game increases in the order of no pseudo-continuous production (1 time) <2 times <3 times <4 times. Is getting higher.

Next, the control configuration of the pachinko gaming machine of this embodiment will be described.
A main control board 30 is mounted on the back side of the pachinko gaming machine. The main control board 30 executes processing related to games in the pachinko gaming machine and outputs various control signals (control commands) according to the result of the processing. An effect control board 31 is mounted on the back side of the machine. The effect control board 31 executes processing related to execution of game effects and the like based on the control signal (control command) output from the main control board 30. That is, the effect control board 31 controls the display mode of the effect display device 10 (display images such as symbols, backgrounds, and characters), the light emission mode of the decoration lamp La, and the sound output mode of the speaker Sp.

Hereinafter, specific configurations of the main control board 30 and the effect control board 31 will be described.
First, the main control board 30 will be described.
As shown in FIG. 3, the main control board 30 includes a main control CPU 30a, a main control ROM 30b, a main control RAM 30c, and a random number circuit 30d. A main control ROM 30b, a main control RAM 30c, and a random number circuit 30d are connected to the main control CPU 30a. A start sensor SE, a count sensor CS, and a gate sensor GS are connected to the main control CPU 30a. Further, a special symbol display device 11, a hold display device 14, and a normal symbol display device 15 are connected to the main control CPU 30a. The main control CPU 30a is connected to a normal electric accessory solenoid SOL1 and a big prize solenoid SOL2.

  The main control CPU 30a executes various processes related to games in the pachinko gaming machine according to predetermined procedures. The main control ROM 30b stores a main control program for the main control CPU 30a to execute processing related to the game. The main control ROM 30b stores a plurality of types of variation patterns. The variation pattern indicates a pattern serving as a base of a game effect (display effect or the like) from when the special symbol variation display is started until the special symbol is fixedly displayed. The variation pattern in the present embodiment is the variation time (effect time) from when the special symbol variation display is started to when the special symbol is confirmed and stopped display, and the variation contents of the decorative symbol variation game during the variation time (effect) Content).

Here, the special symbol variation pattern in the present embodiment will be described.
The special symbol variation pattern of the present embodiment includes a variation pattern for a big hit effect that specifies a big hit effect, a variation pattern for a small hit effect that specifies a small hit effect, and an outlier reach effect that specifies an outlier reach effect. There are a fluctuation pattern and a fluctuation pattern for an off-stage effect that specifies the off-line effect.

  The jackpot effect is an effect in which the decorative symbol variation game is developed so that the symbol combination of the jackpot is finally stopped and displayed after reaching the reach effect. The small hit effect is an effect in which the decorative symbol variation game is developed so that the final symbol combination is finally stopped. The outlier reach effect is an effect that the decorative symbol variation game is developed so that the final symbol combination is finally stopped and displayed through the reach effect. The outlier effect is an effect that is developed so that the decorative symbol variation game finally displays the symbol combinations that are out of place without being subjected to the reach effect.

  Hereinafter, the special symbol variation pattern prepared in the pachinko gaming machine of this embodiment will be described with reference to FIG. In FIG. 4, the column “effect content” indicates whether each special symbol variation pattern is a special symbol variation pattern used for a big hit effect, a small hit effect, a miss reach effect, or a miss effect. The “variable cycle number” column indicates the number of executions of the variable cycle specified by each special symbol variation pattern. The column of “first effect category” indicates whether the specified reach effect is a normal reach effect or a super reach effect in the special symbol variation pattern that specifies the reach effect. In the present embodiment, a high jackpot expectation is set for the super reach production as compared with the normal reach production. Note that the “normal variation effect” shown in the column of “first effect category” is an effect that causes the symbols of each symbol row to be displayed in a fixed stop state without executing the reach effect. In addition, the “shortening variation effect” shown in the column of “first effect category” is an effect that the symbols of each symbol row are confirmed and stopped in a shorter time than the normal variation effect without executing the reach effect. .

  The column of “second effect category” indicates whether the type of the specified super reach effect is the character reach effect or the story reach effect in the special symbol variation pattern that specifies the super reach effect. The type of the super reach effect shown in the “second effect category” indicates a general category of the type of the super reach effect. Note that the character reach effect is a type of reach effect that is performed with effect content that causes a predetermined character to appear, for example. Also, the story reach effect is a type of reach effect that is performed with the effect content in which a predetermined story (story) is developed, for example.

  The column of “third effect category” shows specific effect contents of each reach effect specified in the special symbol variation pattern specifying the character reach effect or the story reach effect. In the present embodiment, three types of effect contents of first to third character reach are prepared for the character reach effect. In addition, three types of production contents of first to third story reach are prepared for the story reach production.

  For example, the special symbol variation pattern HP1 specifies the content of the effect of confirming and stopping the symbol combination of the outliers after executing the normal variation effect without the pseudo continuous effect. In addition, for example, the special symbol variation pattern HP3 for the outlier reach effect specifies the content of the effect in which the outlier symbol combination is confirmed and stopped after executing the normal reach effect without the pseudo continuous effect.

  In addition, for example, the special symbol variation pattern HP12 for the big hit effect specifies the content of the effect for confirming and displaying the big hit symbol combination after executing the first character reach effect without the pseudo continuous effect. In addition, for example, the special symbol variation pattern HP48 for the big hit effect is accompanied by a pseudo continuous effect composed of four change cycles, and the super reach effect (first story reach) is executed in the fourth (final) change cycle. After that, the contents of the effect for definitely stopping and displaying the jackpot symbol combination are specified.

  The main control ROM 30b stores determination values used for determinations relating to games. The determination regarding the game is performed by comparing the random number used for the determination regarding the game with the determination value.

  More specifically, the main control ROM 30b stores a hit determination value used for determining whether or not it is a hit. The hit determination value includes a big hit determination value used for determining whether or not a big hit for granting a big hit game and a small hit used for determining whether or not a small hit for giving a small hit game. There is a judgment value. For the big hit judgment value and the small hit judgment value, a predetermined number of values are determined from numerical values that can be taken by the hit judgment random number that is a 16-bit random number (in this embodiment, all 65536 integer values from 0 to 65535). It has been. The number of jackpot determination values used when the probability variation state is assigned is larger than the number of jackpot determination values used when the probability variation state is not imparted. Further, the big hit determination value and the small hit determination value are each 16-bit numerical data, like the hit determination random number.

  The main control ROM 30b stores a normal hit determination value used for normal hit determination as to whether or not the normal hit for giving the normal hit game. As the normal hit determination value, a predetermined number of values are determined from numerical values that can be taken by the normal hit determination random number that is a 16-bit random number (in this embodiment, all 65536 integer values from 0 to 65535). . The number of normal hit determination values used when the variable state is given is larger than the number of normal hit determination values used when the variable state is not given. The normal hit determination value is 16-bit numerical data, like the normal hit determination random number. The hit determination (big hit determination and small hit determination) and the normal hit determination of the present embodiment are determinations of the type classified into the first system because both are determinations related to whether or not the variable game is successful.

  Further, in the main control ROM 30b, when the affirmative determination is made in the big hit determination, the big hit symbol determination value used for the big hit symbol determination for determining (determining) the special symbol big hit symbol to be confirmed and stopped on the special symbol display device 11 is determined. Is remembered. In the present embodiment, determining the jackpot symbol is also determining the jackpot symbol. The jackpot symbol determination value includes a predetermined number of values for each jackpot symbol out of the numerical values that can be taken by the jackpot symbol random number that is a 16-bit random number (in this embodiment, all 65536 integer values from 0 to 65535). They are assigned to each. The jackpot symbol determination value is 16-bit numeric data, like the jackpot symbol random number.

  In the main control ROM 30b, a small hit symbol used for small hit symbol determination for determining (determining) a special symbol small hit symbol to be confirmed and stopped on the special symbol display device 11 when an affirmative determination is made in the small hit determination. The judgment value is stored. In this embodiment, determining the small hit symbol also means determining the small hit symbol. The small hit symbol determination value includes a predetermined number of values from among the numerical values that can be taken by the small hit symbol random number that is a 16-bit random number (in this embodiment, all 65536 integer values from 0 to 65535). Each hit symbol is assigned. Further, the small hit symbol determination value is 16-bit numerical data, like the small hit symbol random number. The big hit symbol determination and the small hit symbol determination according to the present embodiment are hit type determinations for determining the type of hits to be given to the player, and thus are the types classified into the second system.

  The main control ROM 30b stores a reach determination value used for reach determination as to whether or not to allow execution of reach effects when negative determination is made in the big hit determination and the small hit determination. As the reach determination value, a predetermined number of values are determined from numerical values that can be taken by a reach determination random number that is a 16-bit random number (in this embodiment, all 65536 integer values from 0 to 65535). Similarly to the reach determination random number, the reach determination value is 16-bit numerical data.

  The main control ROM 30b stores a first distribution determination value used for primary distribution determination for determining (determining) whether the number of fluctuation cycles is 1 (no pseudo continuous production) to 4 times. Has been. In the present embodiment, determining the number of fluctuation cycles by primary distribution determination is also determining the number of fluctuation cycles. The first distribution determination value is a predetermined number of values among the numerical values that can be taken by the first variation pattern distribution random numbers that are 16-bit random numbers (in this embodiment, all 65536 integer values from 0 to 65535). Are assigned to the number of times of 1 (no pseudo-continuous production) to 4 fluctuation cycles. Further, the first distribution determination value is 16-bit numerical data, like the first variation pattern distribution random number.

  In addition, when the determination result of the big hit determination is negative, that is, the first distribution determination value used for the determination of the special symbol variation pattern for the loss effect or the loss reach effect is a ratio determined as the number of change cycles increases. The numerical values that can be taken by the random numbers for first variation pattern distribution are distributed to the number of variable cycles. In addition, when the determination result of the big hit determination is affirmative, that is, the first distribution determination value used for the determination of the special symbol fluctuation pattern for the big hit effect is such that the ratio to be determined increases as the number of fluctuation cycles increases. In addition, numerical values that can be taken by the first variation pattern distribution random numbers are distributed.

  In the main control ROM 30b, when the determination result of reach determination is affirmative, the second distribution determination value used for secondary distribution determination for determining (determining) which of normal reach effect and super reach effect is to be used. Is remembered. In the present embodiment, determining the reach effect by the secondary distribution determination also determines which of the normal reach effect and the super reach effect is to be determined. The second distribution determination value is a predetermined number of values among the numerical values that can be taken by the second variation pattern distribution random number that is an 8-bit random number (in this embodiment, all 256 integer values from 0 to 255). Are assigned to the normal reach production and the super reach production. Further, the second distribution determination value is 8-bit numerical data, like the second variation pattern distribution random number.

  In addition, when the determination result of the big hit determination is negative, that is, the second distribution determination value used for the determination of the special symbol variation pattern for the outlier reach effect is a ratio at which the super reach effect is determined as compared with the normal reach effect. Is assigned a numerical value that can be taken by the random numbers for the second variation pattern distribution. In addition, when the determination result of the big hit determination is affirmative, that is, the second distribution determination value used for the determination of the special symbol variation pattern for the big hit effect has a ratio of determining the super reach effect compared with the normal reach effect. Numerical values that can be taken by the random numbers for second variation pattern distribution are distributed so as to be higher.

  In the main control ROM 30b, when the execution of the super reach effect is determined (determined), a third distribution determination used to determine (determine) which one of the character reach effect and the story reach effect is to be determined (determined). The distribution determination value is stored. In the present embodiment, determining the type of the super reach effect by the tertiary distribution determination also determines which of the character reach effect and the story reach effect is to be determined. The third distribution determination value is a predetermined number of values from numerical values that can be taken by the third variation pattern distribution random number that is an 8-bit random number (in this embodiment, all 256 integer values from 0 to 255). Are assigned to the normal reach production and the super reach production. The third distribution determination value is 8-bit numerical data, like the third variation pattern distribution random number.

  The main control ROM 30b is used for quaternary distribution determination as to which production content is to be selected from a plurality of types of production content when the execution of the character reach production or the story reach production is determined (determined). The fourth distribution determination value to be stored is stored. In the present embodiment, determining the specific effect content by the quaternary distribution determination is also determining the specific effect content of each super reach effect. The fourth distribution determination value is a predetermined number of values among the numerical values that can be taken by the fourth variation pattern distribution random number that is an 8-bit random number (in this embodiment, all 256 integer values from 0 to 255). Are assigned to each production content. The fourth distribution determination value is 8-bit numerical data, like the fourth variation pattern distribution random number.

  In the present embodiment, the reach determination and the primary to quaternary distribution determination are special symbol variation patterns that specify the variation content of the decorative symbol variation game, that is, the effect determination for determining the content of the game effect. It is a judgment of the kind classified into three systems. As described above, in the pachinko gaming machine of the present embodiment, the determination regarding the game is classified into the first system, the second system, and the third system in terms of the magnitude of the influence on the game result (player's profit). Classification is possible by stratification. In addition, since each system has a plurality of types of determinations, the first to third systems are all specific systems.

  The main control RAM 30c stores various types of information (random values, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine. For example, the main control RAM 30c stores a main probability change flag indicating whether or not a probability change state is given. The main control RAM 30c stores a main operation flag indicating whether or not the variable state is given.

  Next, the random number circuit 30d will be described in detail with reference to FIG. The random number circuit 30d generates hardware random numbers used for various determinations relating to games. The random number circuit 30d includes a clock oscillator CH, a first random number generation circuit Rs1, a second random number generation circuit Rs2, a third random number generation circuit Rs3, a fourth random number generation circuit Rs4, a first latch circuit Lt1, a second latch circuit Lt2, A third latch circuit Lt3 and a fourth latch circuit Lt4 are provided. The first random number generation circuit Rs1 includes a first update monitoring circuit Ks1, and the second random number generation circuit Rs2 includes a second update monitoring circuit Ks2.

  The clock oscillator CH outputs an electrical signal generated at a constant frequency (oscillation frequency) by a quartz oscillation circuit (not shown) or the like as a “clock signal” to each of the random number generation circuits Rs1 to Rs4.

  The first random number generation circuit Rs1 and the second random number generation circuit Rs2 are circuits that generate a 16-bit random number value. Since the second power of 2 is 65536, the first random number generation circuit Rs1 and the second random number generation circuit Rs2 update the random number value in the numerical range of 0 to 65535. The third random number generation circuit Rs3 and the fourth random number generation circuit Rs4 are circuits that generate an 8-bit random number value. Since the second power of 2 is 256, the third random number generation circuit Rs3 and the fourth random number generation circuit Rs4 update the random number values in the numerical range of 0 to 255.

  Each random number generation circuit Rs1 to Rs4 of the present embodiment updates (counts) the random number value once every time the clock signal from the clock oscillator CH is input. The oscillation frequency of the clock oscillator CH in this embodiment is set to 10 MHz. Therefore, each of the random number generation circuits Rs1 to Rs4 updates the random number value once every 0.1 μs. That is, in the first random number generation circuit Rs1 and the second random number generation circuit Rs2, the time required until the random number value is updated is 65536 × 0.1 μs = 6.5536 ms. On the other hand, in the third random number generation circuit Rs3 and the fourth random number generation circuit Rs4, the time required until the random number value is updated is 256 × 0.1 μs = 0.0256 ms. In the present embodiment, the frequency (output cycle) of the clock signal for each of the random number generation circuits Rs1 to Rs4 is a predetermined update cycle.

  Further, when each random number generation circuit Rs1 to Rs4 has updated to the upper limit random number value, it returns to 0 and updates the random number value. In addition, each random number generation circuit Rs1 to Rs4 determines the hardware initial value individually and randomly when the update of the random number value within the predetermined numerical range is completed, and the random number generation circuits Rs1 to Rs4 Update the number.

  For example, if the first random number generation circuit Rs1 updates the random number value from 0 to 65535 in order and then determines “2012” as the hardware initial value, it updates the random value from 2012 to 65535 in order and then returns to 0. Thus, the random number value is updated from 0 to 2011. That is, in each of the random number generation circuits Rs1 to Rs4, the order (arrangement) of the random numbers to be updated may be different for each update cycle. That is, according to the previous example, the first set value is “0” in the first update cycle, while “2012” is set first in the next update cycle.

  Further, in each of the random number generation circuits Rs1 to Rs4, the random value is updated for each, and the random value is generated for each. In each of the random number generation circuits Rs1 to Rs4, the hardware initial value is determined separately. For this reason, it is very unlikely that the values updated in the random number generation circuits Rs1 to Rs4 are the same value.

  As described above, in this embodiment, the random number values updated by the random number generation circuits Rs1 to Rs4 are numerical data, and the random number generation circuits Rs1 to Rs4 each function as update means for updating the numerical data at a predetermined update cycle. To do. In the present embodiment, each of the random number generation circuits Rs1 and Rs2 functions as an updating unit that updates the numerical data within a numerical range of 0 to 65535 as the first numerical range. Each of the random number generation circuits Rs3 and Rs4 functions as update means for updating numerical data within a numerical range of 0 to 255 as a second numerical range that is narrower than the first numerical range.

  Accordingly, each random number generation circuit Rs1, Rs2 functions as a first updating unit, while each random number generation circuit Rs3, Rs4 is a second that can update numerical data in a manner different from each random number generation circuit Rs1, Rs2. Functions as update means. In each of the random number generation circuits Rs1 to Rs4, since the hardware initial value is changed every time the update of the random number is completed, in principle, different random numbers are constantly updated. From this point of view, it can be said that each of the random number generation circuits Rs1 to Rs4 updates the random number value in a different manner.

  The first random number generation circuit Rs1 is the first latch circuit Lt1, the second random number generation circuit Rs2 is the second latch circuit Lt2, the third random number generation circuit Rs3 is the third latch circuit Lt3, and the fourth random number generation circuit Rs4. Are respectively connected to the fourth latch circuit Lt4. As will be described later, each of the latch circuits Lt1 to Lt4 is configured to be able to input a latch signal output from the main control CPU 30a in a special symbol input process or a normal symbol input process.

  When receiving the latch signal, the first latch circuit Lt1 latches the random number value updated by the first random number generation circuit Rs1 at that time in the buffer. When receiving the latch signal, the second latch circuit Lt2 latches the random number value updated by the second random number generation circuit Rs2 at that time in the buffer. When the latch signal is input, the third latch circuit Lt3 latches the random number value updated by the third random number generation circuit Rs3 at that time in the buffer. When the latch signal is input, the fourth latch circuit Lt4 latches the random number value updated by the fourth random number generation circuit Rs4 at that time in the buffer. The random values latched by the latch circuits Lt1 to Lt4 are acquired as random numbers used for determination regarding the game by the main control CPU 30a in the special symbol input process and the normal symbol input process, as will be described later.

  As shown in FIG. 6, the random number value latched by the first latch circuit Lt1 is acquired by the main control CPU 30a as a hit determination random number used for the hit determination (big hit determination and small hit determination). That is, the numerical values that can be taken by the random numbers for hit determination according to the present embodiment are 65536 integer values from 0 to 65535 as described above.

  The random number value latched by the first latch circuit Lt1 is acquired by the main control CPU 30a as the normal hit determination value used for the normal hit determination. That is, the numerical values that can be taken by the random numbers for ordinary hit determination according to the present embodiment are all 65536 integer values from 0 to 65535 as described above.

  The random number value latched by the second latch circuit Lt2 is acquired by the main control CPU 30a as a big hit symbol random number used for the big hit symbol determination. The random number value latched by the second latch circuit Lt2 is acquired by the main control CPU 30a as a small hit symbol random number used for the small hit symbol determination. The random value latched by the second latch circuit Lt2 is acquired by the main control CPU 30a as a reach determination random number used for reach determination. The random number value latched by the second latch circuit Lt2 is acquired by the main control CPU 30a as a first variation pattern distribution random number used for primary distribution determination. Therefore, the numerical values that can be taken by the big hit symbol random number, the small hit symbol random number, the reach determination random number, and the first variation pattern distribution random number according to the present embodiment are all in the range of 0536 to 65536. It becomes a numerical value.

  The random value latched by the third latch circuit Lt3 is acquired by the main control CPU 30a as the second variation pattern distribution random number used for the secondary distribution determination. The random number value latched by the third latch circuit Lt3 is acquired by the main control CPU 30a as a third variation pattern distribution random number used for the tertiary distribution determination. Therefore, the numerical values that can be taken by the second variation pattern distribution random numbers and the third variation pattern distribution random numbers in this embodiment are all 256 integer values from 0 to 255 as described above.

  The random number value latched by the fourth latch circuit Lt4 is acquired by the main control CPU 30a as the fourth variation pattern distribution random number used for the quaternary distribution determination. Therefore, the numerical values that can be taken by the fourth variation pattern distribution random numbers of the present embodiment are all 256 integer values from 0 to 255 as described above.

  As shown in FIG. 5, the first update monitoring circuit Ks1 and the second update monitoring circuit Ks2 are circuits that monitor whether or not the random number values are normally updated by the random number generation circuits Rs1 and Rs2. The first update monitoring circuit Ks1 is connected to the first random number generation circuit Rs1, and the second update monitoring circuit Ks2 is connected to the second random number generation circuit Rs2. Each update monitoring circuit Ks1, Ks2 monitors the frequency (input period) of the clock signal input to each random number generation circuit Rs1, Rs2, for example, and updates the random number value when the frequency falls below a predetermined frequency. Detect that is not done properly.

  When each update monitoring circuit Ks1, Ks2 detects that the random number value is not normally updated, it sets update abnormality information indicating an abnormality in updating the random number value in an internal information register (not shown). In this way, each update monitoring circuit Ks1, Ks2 functions as an abnormality detection unit capable of detecting an abnormality in updating the random number value by each random number generation circuit Rs1, Rs2.

Next, the effect control board 31 will be described.
As shown in FIG. 3, the effect control board 31 includes an effect control CPU 31a, an effect control ROM 31b, and an effect control RAM 31c, and the effect control CPU 31a includes an effect control ROM 31b and an effect control. A RAM 31c is connected. In addition, the effect display CPU 10, the decoration lamp La, and the speaker Sp are connected to the effect control CPU 31a. The effect control CPU 31a updates the values of various random numbers at predetermined intervals, stores (sets) the updated values in the setting area of the effect control RAM 31c, and rewrites the values before the update.

  The effect control ROM 31b stores an effect control program for executing processing relating to the execution of game effects and the like, and various image data (various image data such as symbols, background images, characters, and characters). . The effect control RAM 31c stores various information (random values, timer values, flags, etc.) that are appropriately rewritten during operation of the pachinko gaming machine.

Hereinafter, the control contents executed by the main control board 30 and the effect control board 31 will be described.
First, various processes such as a special symbol input process and a special symbol start process executed by the main control CPU 30a of the main control board 30 based on the main control program will be described. In the present embodiment, the main control CPU 30a executes various processes such as a special symbol input process and a special symbol start process every predetermined control cycle (for example, 4 ms).

First, the special symbol input process will be described.
As shown in FIG. 7, the main control CPU 30a enters whether or not a game ball has entered the entrance of the start port 12 and a detection signal output from the start sensor SE that has detected the game ball has been input. Ball determination is performed (step S11). When the determination result in step S11 is negative, the main control CPU 30a ends the special symbol input process. On the other hand, if the determination result in step S11 is affirmative, the main control CPU 30a determines whether or not the number of special symbol reservations stored in the main control RAM 30c is less than the upper limit number (4 in the present embodiment). Symbol hold determination is performed (step S12).

  When the determination result in step S12 is negative (when the number of special symbol reservations is 4), the main control CPU 30a does not rewrite the special symbol reservation number exceeding the upper limit number and does not acquire various random number values. Then, the special symbol input process is terminated. On the other hand, if the determination result in step S12 is affirmative (if the number of special symbol reservations is less than 4), the main control CPU 30a adds 1 to the number of special symbol reservations and rewrites the number of special symbol reservations (step S13). Further, when the determination in step S12 is affirmative, the main control CPU 30a acquires various random number values from the random number circuit 30d (steps S14 to S21).

  More specifically, in step S14, the main control CPU 30a outputs a latch signal to the first latch circuit Lt1. Then, the main control CPU 30a acquires the random number value latched by the first latch circuit Lt1 as a hit determination random number when the latch signal is input, and stores it in the main control RAM 30c. That is, in step S14, the main control CPU 30a acquires and stores the random number value updated by the first random number generation circuit Rs1 from the first random number generation circuit Rs1 as a hit determination random number.

  Next, in step S15, the main control CPU 30a outputs a latch signal to the second latch circuit Lt2. Then, the main control CPU 30a acquires the random number value latched by the second latch circuit Lt2 as a big hit symbol random number triggered by the input of the latch signal, and stores it in the main control RAM 30c. Subsequently, in step S16, the main control CPU 30a outputs a latch signal to the second latch circuit Lt2. Then, the main control CPU 30a acquires the random number value latched by the second latch circuit Lt2 when the latch signal is input as a small hitting design random number and stores it in the main control RAM 30c.

  Next, in step S17, the main control CPU 30a outputs a latch signal to the second latch circuit Lt2. Then, the main control CPU 30a acquires the random number value latched by the second latch circuit Lt2 when the latch signal is input as a reach determination random number and stores it in the main control RAM 30c. Subsequently, in step S18, the main control CPU 30a outputs a latch signal to the second latch circuit Lt2. Then, the main control CPU 30a acquires the random number value latched by the second latch circuit Lt2 when the latch signal is input as the first variation pattern distribution random number, and stores it in the main control RAM 30c.

  As described above, in steps S15 to S18, the main control CPU 30a changes the random value updated by the second random number generation circuit Rs2 from the second random number generation circuit Rs2 to the big hit symbol random number, the small hit symbol random number, the reach It is acquired and stored as a random number for determination and a random number for first variation pattern distribution. Here, in the pachinko gaming machine according to the present embodiment, the random number generation circuits Rs1 to Rs4 update the random number value once for the time from the execution of the process of one step to the execution of the process of the next step. It is set to a time longer than the update cycle necessary for this. That is, each of the random number generation circuits Rs1 to Rs4 updates the random number value with an update cycle of a time shorter than the shortest time from when the main control CPU 30a acquires the random number value until the next random number value is acquired. For this reason, in this embodiment, even in the case where the random number values are continuously acquired from the same random number generation circuit in a plurality of consecutive steps (processes), different random number values can be acquired. As described above, in the special symbol input process, the main control CPU 30a acquires the random number value updated by the random number generation circuit from one random number generation circuit as a random number used for different types of determinations at different timings.

  Next, in step S19, the main control CPU 30a outputs a latch signal to the third latch circuit Lt3. Then, the main control CPU 30a acquires the random number value latched by the third latch circuit Lt3 when the latch signal is input as a second variation pattern distribution random number, and stores it in the main control RAM 30c. Subsequently, in step S20, the main control CPU 30a outputs a latch signal to the third latch circuit Lt3. Then, the main control CPU 30a acquires the random number value latched by the third latch circuit Lt3 when the latch signal is input as a third variation pattern distribution random number, and stores it in the main control RAM 30c. That is, in step S19 and step S20, the main control CPU 30a changes the random number value updated by the third random number generation circuit Rs3 from the third random number generation circuit Rs3 to the second variation pattern distribution random number or the third variation. Acquired and stored as pattern distribution random numbers.

  Next, in step S21, the main control CPU 30a outputs a latch signal to the fourth latch circuit Lt4. Then, the main control CPU 30a acquires the random number value latched by the fourth latch circuit Lt4 as a fourth fluctuation pattern distribution random number when the latch signal is input, and stores it in the main control RAM 30c. That is, in step S21, the main control CPU 30a acquires and stores the random number value updated by the fourth random number generation circuit Rs4 from the fourth random number generation circuit Rs4 as the fourth variation pattern distribution random number.

  In steps S14 to S21, the main control CPU 30a stores the acquired various random number values in the main control RAM 30c so that the order in which the various random number values are stored can be specified. Thereafter, the main control CPU 30a ends the special symbol input process.

  As described above, the main control CPU 30a functions as an acquisition unit and a random number acquisition unit because the values latched by the latch circuits Lt1 to Lt4 are acquired as random numbers. Further, the main control CPU 30a functions as a storage unit because the main control RAM 30c stores a value acquired as a random number.

  Further, the main control CPU 30a uses the second random number generation circuit Rs2 to determine whether the random number value updated by the second random number generation circuit Rs2 is classified into the second system or to the big hit symbol determination or the small hit symbol determination. Obtained as a random number to use. Further, the main control CPU 30a determines whether the random number value updated by the third random number generation circuit Rs3 from the third random number generation circuit Rs3 is classified into the third system among the secondary distribution determination and the tertiary distribution. Acquired as a random number used for determination. In this way, in the special symbol input process, the main control CPU 30a acquires the random number value updated by the random number generation circuit from one random number generation circuit as a random number used for a plurality of types of determination among the determinations of the specific system. To do.

  Further, the main control CPU 30a acquires the random number value updated by the first random number generation circuit Rs1 from the first random number generation circuit Rs1 as a random number used for the determination of the first system. On the other hand, the main control CPU 30a acquires, from the third random number generation circuit Rs3, the random number value updated by the third random number generation circuit Rs3 as a random number used for the determination of the third system. That is, in the special symbol input process, the main control CPU 30a uses different random numbers from the plurality of random number generation circuits among the random number generation circuits Rs1 to Rs4 to update the random number values individually updated by the plurality of random number generation circuits. It is acquired as a random number used for the determination classified as.

  Further, the main control CPU 30a uses the random number value updated by the third random number generation circuit Rs3 from the third random number generation circuit Rs3 to the secondary distribution determination and the tertiary distribution determination in the third system determination. Obtained as a random number to use. On the other hand, the main control CPU 30a uses the random number value updated by the second random number generation circuit Rs2 from the second random number generation circuit Rs2 to reach determination or primary distribution determination among the determinations classified into the third system. Obtained as a random number to use. In the present embodiment, the secondary distribution determination and the tertiary distribution determination are a plurality of types of determination among the determinations of the specific system, and the reach determination and the primary distribution determination are of some types. This type of determination is different from the determination.

Next, the special symbol start process will be described.
As shown in FIG. 8, the main control CPU 30a determines whether or not the execution condition of the special symbol variation game is satisfied (step S22). In step S22, the main control CPU 30a determines whether or not a special symbol variation game or a winning game is in progress. If the determination result in step S22 is negative (during a special symbol variation game or a winning game), the main control CPU 30a ends the special symbol start process.

  On the other hand, when the determination result of step S22 is affirmative (when the special symbol variation game is not being executed and the winning game is not being played), the main control CPU 30a has a special symbol hold count stored in the main control RAM 30c. It is determined whether it is larger than 0 (step S23). When the determination result of step S23 is negative (when the number of special symbol hold = 0), the main control CPU 30a ends the special symbol start process. On the other hand, when the determination result of step S23 is affirmative (when the number of special symbol hold> 0), the main control CPU 30a subtracts 1 from the number of special symbol hold and rewrites the number of special symbol hold (step S24).

  Next, the main control CPU 30a, among various random numbers stored in the main control RAM 30c, stores the random numbers stored first (random numbers for hit determination, random numbers for big hit symbols, small hit symbols) A random number, a reach determination random number, and first to fourth variation pattern distribution random numbers) are acquired (step S25).

  Next, as shown in FIG. 9, the main control CPU 30a determines whether or not the acquired hit determination random number value matches the big hit determination value stored in the main control ROM 30b (step S30). S26). In step S26, the main control CPU 30a uses the jackpot determination value for the probability variation state when the probability variation state is imparted, and uses the jackpot determination value for the non-probability variation state when the probability variation state is not imparted. . When the determination result of step S26 is affirmative (in the case of a big hit), the main control CPU 30a causes the special symbol display device 11 to display a fixed stop based on the value of the big win symbol random number based on the value of the big hit symbol random number. The final stop symbol is determined (step S27). More specifically, in step S27, the main control CPU 30a compares the jackpot symbol random number value with the jackpot symbol determination value stored in the main control ROM 30b, and matches the jackpot symbol random number value. The special symbol to which the determination value is distributed is determined (determined) as the final stop symbol.

  Next, the main control CPU 30a performs primary to quaternary distribution determination based on the obtained first to fourth variation pattern distribution random numbers, and from among the special symbol variation patterns for the jackpot effect. One special symbol variation pattern is determined (step S28).

  More specifically, in step S28, the main control CPU 30a compares the first variation pattern distribution random number value with the first distribution determination value stored in the main control ROM 30b, and first variation pattern distribution. It is determined (determined) as the number of fluctuation cycles to which the first distribution determination value that matches the value of the random number for distribution is distributed.

  Next, the main control CPU 30a compares the value of the second variation pattern distribution random number with the second distribution determination value stored in the main control ROM 30b, and compares the value of the second variation pattern distribution random number. It is determined (determined) as the production content (normal reach production or super reach production) to which the second distribution determination value that matches is assigned.

  Next, the main control CPU 30a compares the value of the third variation pattern distribution random number with the third distribution determination value and determines the third variation when determining that it is a super reach effect in the secondary distribution determination. The effect content (character reach effect or story reach effect) to which the third distribution determination value that matches the pattern distribution random number value is distributed is determined (determined).

  Next, the main control CPU 30a compares the value of the fourth variation pattern distribution random number with the fourth distribution determination value stored in the main control ROM 30b, and determines the value of the fourth variation pattern distribution random number. It is determined that the content is the specific content assigned to the fourth distribution determination value. That is, when the CPU 30a for main control determines the character reach effect in the tertiary distribution determination, the main control CPU 30a determines and determines one of the first to third character reach as specific effect contents of the character reach effect. . In addition, when the main control CPU 30a determines the story reach effect in the tertiary distribution determination, the main control CPU 30a determines and determines one of the first to third story reach as specific effect contents of the story reach effect. .

  In step S28, the main control CPU 30a determines the special symbol variation pattern for the jackpot effect that matches the determination result of the primary to quaternary allocation determination as the special symbol variation pattern used in the current special symbol variation game. To do. The main control CPU 30a ends the special symbol start process when the process of step S28 is completed.

  If the determination result in step S26 is negative (not a big hit), the main control CPU 30a determines whether or not the value of the random number for hit determination matches the small hit determination value stored in the main control ROM 30b. Is determined (step S29). If the determination result in step S29 is affirmative (in the case of small hits), the main control CPU 30a changes the special symbol display device 11 from among the small hit symbols based on the special symbols based on the acquired value of random numbers for small hit symbols. The final stop symbol to be confirmed and stopped is determined (step S30). More specifically, in step S30, the main control CPU 30a compares the small hit symbol random number value with the small hit symbol determination value stored in the main control ROM 30b, and matches the small hit symbol random value. The special symbol to which the small hit symbol determination value is assigned is determined (determined) as the final stop symbol.

  Next, the main control CPU 30a determines one special symbol variation pattern from the special symbol variation patterns for the small hit effect based on the first to fourth variation pattern distribution random numbers (step S31). . In step S31, the main control CPU 30a determines the special symbol variation pattern for the small hit effect that matches the determination result of the primary to quaternary allocation determination as the special symbol variation pattern used in the current special symbol variation game. decide. Since the specific processing content of step S31 is the same as that of step S28, detailed description is omitted. The main control CPU 30a ends the special symbol start process when the process of step S31 is completed.

  When the determination result of step S29 is negative (in the case of a loss), the main control CPU 30a determines whether or not the acquired reach determination random number value matches the reach determination value stored in the main control ROM 30b. The reach determination is performed (step S32). When the determination result in step S32 is affirmative (when reach production is present), the main control CPU 30a determines a final stop symbol to be displayed on the special symbol display device 11 in a fixed stop manner from among the symbols that are out of the special symbol (step S32). S33). Note that, in step S33, the main control CPU 30a uniquely determines a single special symbol detachment symbol.

  Next, the main control CPU 30a determines one special symbol variation pattern from the variation patterns for the outlier reach effect based on the first to fourth variation pattern distribution random numbers (step S34). In step S34, the main control CPU 30a determines the special symbol variation pattern for the outlier reach effect that matches the determination result of the primary to quaternary allocation determination as the special symbol variation pattern used in the current special symbol variation game. decide. Since the specific processing content of step S34 is the same as that of step S28, detailed description is omitted. Thereafter, the main control CPU 30a ends the special symbol start process.

  If the determination result in step S32 is negative (when no reach effect is present), the main control CPU 30a determines a final stop symbol to be displayed on the special symbol display device 11 in a fixed stop manner from among the symbols that are out of the special symbol. (Step S35). In step S35, the main control CPU 30a unambiguously determines the one-off special symbols.

  Next, the main control CPU 30a determines one special symbol variation pattern from among the variation patterns for the offending effect based on the first to fourth variation pattern distribution random numbers (step S36). In step S36, the main control CPU 30a can determine the special symbol variation pattern HP2 when a value indicating that the variable state is given to the main operation flag is set. On the other hand, the main control CPU 30a does not determine the special symbol variation pattern HP2 (determines the special symbol variation pattern HP1) when a value indicating that the variable state is given to the main operation flag is not set. ). Thereafter, the main control CPU 30a ends the special symbol start process.

  Thereafter, in a process different from the special symbol start process, the main control CPU 30a relates to a special symbol variation game, such as outputting a predetermined control command at a predetermined timing to the effect control board 31 (effect control CPU 31a). Perform various processes. Specifically, the main control CPU 30a outputs a variation pattern designation command for designating a special symbol variation pattern and instructing the start of variation of the decorative symbol. Further, the main control CPU 30a controls the display content of the special symbol display device 11 so as to start the variable symbol variation display. Further, the main control CPU 30a starts measuring the effect time of the special symbol variation game. Further, the main control CPU 30a outputs a special symbol designation command for designating the final stop symbol.

  The main control CPU 30a controls the display content of the special symbol display device 11 so as to display the determined final stop symbol based on the variation time determined in the special symbol variation pattern determined in the special symbol start process. To do. Further, the main control CPU 30a instructs all the symbols for designating and stopping the symbol combination at the end of the variation time set in the special symbol variation pattern determined in the special symbol start processing, and displaying the symbol combination in a fixed stop manner. Output a stop command.

Next, a process performed by the main control CPU 30a to give a winning game will be described.
First, the process performed to grant a big hit game will be described.
The main control CPU 30a specifies the type of jackpot game to be given based on the jackpot symbol of the special symbol determined (determined) when the affirmative determination is made in the jackpot determination (that is, the type of jackpot). Then, the main control CPU 30a starts control of the big hit game specified based on the special symbol big hit symbol after the special symbol variation game ends, and sends a predetermined control command to the effect control CPU 31a. Output at timing.

  Specifically, the main control CPU 30a first outputs an opening command for instructing execution of the opening effect when the special symbol variation game that is a big hit ends. Next, the main control CPU 30a outputs a round command instructing the start of the round game every time the round game is started after the opening time has elapsed. The main control CPU 30a controls the big prize solenoid SOL2 to open the big prize opening door 13a with the start of the round game, thereby opening the big prize opening 13 and the first and second ends. Upon receipt of any of the conditions, the special winning opening door 13a is closed to close the special winning entry port 13. Then, when the final round game is finished, the main control CPU 30a outputs an ending command for instructing execution of the ending effect. The main control CPU 30a ends the big hit game by ending the ending effect when the ending time has elapsed.

  Further, when the big hit game is ended, the main control CPU 30a specifies whether or not to give a probability variation state based on the type of special symbol that becomes the big hit symbol (that is, the type of big hit). When assigning the probability variation state, the main control CPU 30a sets a value indicating that the probability variation state is imparted to the main probability variation flag. The main control CPU 30a erases the value of the main probability change flag when the big hit game is awarded.

  Further, when the big hit game is ended, the main control CPU 30a specifies whether or not to give the variable state based on the type of the special symbol that becomes the big hit symbol (that is, the type of the big hit). When assigning the variable state, the main control CPU 30a sets a value indicating that the variable state is provided to the main operation flag. In addition, when it is specified that a variable state in which the number of operations is determined is specified from the special symbol that is the big hit symbol, the main control CPU 30a stores the number of operations that can be specified from the special symbol in the main control RAM 30c. Let

  Each time the special symbol variation game is executed, the main control CPU 30a rewrites the number of operations stored in the main control RAM 30c by one, and when the number of operations becomes 0 as a result of subtracting one, the main control CPU 30a operates. The value of the main operation flag is erased with the end of the special symbol variation game in which the number of times becomes zero. The main control CPU 30a deletes the main operation flag and the number of operations when the big hit game is awarded.

  Next, a process performed for giving a small hit game will be described. The main control CPU 30a specifies the type of the small hit game to be provided based on the small hit symbol (that is, the type of the small hit) of the special symbol determined when an affirmative determination is made in the small hit determination. Then, after the end of the special symbol variation game, the main control CPU 30a starts the control of the small hit game specified based on the special symbol small hit symbol, and sends a predetermined control command to the effect control CPU 31a. Output at a predetermined timing.

  Specifically, the main control CPU 30a, when the special symbol variation game that is a small hit, ends, controls the big prize solenoid SOL2 to open the big prize opening door 13a to open the big prize opening 13. . Then, the main control CPU 30a closes the special prize opening 13 by closing the special prize opening door 13a when one of the first and second termination conditions is satisfied, and ends the small hit game.

Next, processing executed by the main control CPU 30a for normal symbols will be described.
The main control CPU 30a executes various processes such as a normal symbol input process and a normal symbol start process based on the main control program. In the present embodiment, the main control CPU 30a executes various processes such as a normal symbol input process and a normal symbol start process every predetermined control period (for example, 4 ms).

First, the normal symbol input process will be described.
As shown in FIG. 10, the main control CPU 30a determines whether or not the game ball has entered the operation gate 16 and whether or not a detection signal output from the gate sensor GS that has detected the game ball has been input is a normal ball entry determination. This is performed (step S37). When the determination result in step S37 is negative, the main control CPU 30a ends the normal symbol input process. On the other hand, if the determination result in step S37 is affirmative, the main control CPU 30a determines whether or not the number of normal symbol reservations stored in the main control RAM 30c is less than the upper limit number (4 in this embodiment). A hold determination is made (step S38).

  When the determination result in step S38 is negative (when the number of normal symbol hold = 4), the main control CPU 30a does not rewrite the normal symbol hold number exceeding the upper limit number, and obtains the value for the normal hit determination random number. The normal symbol input process is terminated without doing so. On the other hand, if the determination result in step S38 is affirmative (if the number of reserved symbols for ordinary symbols <4), the main control CPU 30a adds 1 to the number of ordinary symbols retained and rewrites the number of ordinary symbols retained (step S39). .

  Next, the main control CPU 30a obtains the normal hit determination random number from the random number circuit 30d (step S40). More specifically, in step S40, the main control CPU 30a outputs a latch signal to the first latch circuit Lt1. Then, the main control CPU 30a acquires the random value latched by the first latch circuit Lt1 as a normal hit determination random number when the latch signal is input, and stores it in the main control RAM 30c. That is, in step S40, the main control CPU 30a acquires and stores the random number value updated by the first random number generation circuit Rs1 from the first random number generation circuit Rs1 as a normal hit determination random number.

  At this time, the main control CPU 30a stores the acquired normal hit determination random number in the main control RAM 30c so that the order in which the normal hit determination random number is stored can be specified. Thereafter, the main control CPU 30a ends the normal symbol input process.

  As described above, the main control CPU 30a acquires, from the first random number generation circuit Rs1, the random number value updated by the first random number generation circuit Rs1 as a hit determination random number in step S14 of the special symbol input process. On the other hand, in step S40 of the normal symbol input process, it is acquired as a normal hit determination random number. That is, in the pachinko gaming machine according to the present embodiment, a random number value updated by the random number generation circuit is input from one random number generation circuit as a first design process group including a plurality of processing steps (steps). The random numbers used for different types of determination are acquired in the process and the normal symbol input process as the second process step group including a plurality of process steps.

Next, the normal symbol start process will be described.
As shown in FIG. 11, the main control CPU 30a determines whether or not the execution condition of the normal symbol variation game is satisfied (step S41). In step S41, the main control CPU 30a determines whether or not the normal symbol variation game or the normal hit game is being played. If the determination result in step S41 is negative (in a normal symbol variation game or a normal hit game), the main control CPU 30a ends the normal symbol start process.

  On the other hand, when the determination result of step S41 is affirmative (when the normal symbol variation game is not being executed and the normal winning game is not being played), the main control CPU 30a has a normal symbol hold count of 0. Is also determined whether it is larger (step S42). When the determination result of step S42 is negative (when the number of normal symbol holds = 0), the normal symbol start process is terminated. On the other hand, when the determination result of step S42 is affirmative (when the number of normal symbol hold> 0), the main control CPU 30a subtracts 1 from the number of normal symbol hold and rewrites the number of normal symbol hold (step S43).

  Next, the main control CPU 30a obtains the value of the normal hit determination random number stored first among the values of the normal hit determination random numbers stored in the main control RAM 30c (step S44). Next, the main control CPU 30a performs a normal hit determination as to whether or not the acquired value of the normal hit determination random number matches the normal hit determination value stored in the main control ROM 30b (step S45). In step S45, the main control CPU 30a uses the normal hit judgment value for the variable state when the variable state is provided, while it does not apply for the variable state when the variable state is not provided. Use the normal hit judgment value. By selecting the normal hit determination value according to the gaming state, the probability of affirmative determination in the normal hit determination varies with high probability during the variable state.

  When the determination result of step S45 is affirmative (in the case of normal hit), the main control CPU 30a determines the normal hit symbol based on the normal symbol as the final stop symbol to be confirmed and stopped on the normal symbol display device 15 (step S46). . In step S46, the main control CPU 30a uniquely determines all the normal symbols of the normal symbols.

  Next, the main control CPU 30a determines one normal symbol variation pattern from among a plurality of types of normal symbol variation patterns (step S47). At this time, if the variable state is not given, the main control CPU 30a determines the normal symbol fluctuation pattern that defines the first fluctuation time (for example, 5 seconds), while being given the variable state. In this case, a normal symbol variation pattern that defines a second variation time (for example, 1 second) shorter than the first variation time is determined. By selecting the normal symbol variation pattern having different variation times according to the gaming state, the variation time of the normal symbol variation game is shortened during the variation state. The main control CPU 30a ends the normal symbol start process when the process of step S47 is completed.

  If the determination result in step S45 is negative (normally off), the main control CPU 30a determines the normal stop symbol by the normal symbol as a final stop symbol to be displayed on the normal symbol display device 15 in a fixed stop display (step S45). S48). Note that in step S48, the main control CPU 30a uniquely determines all the normal symbols out of the normal symbols. Next, the main control CPU 30a determines one normal symbol variation pattern from among a plurality of types of normal symbol variation patterns (step S47). The main control CPU 30a ends the normal symbol start process when the process of step S47 is completed.

  Further, in a process different from the normal symbol start process, the main control CPU 30a controls the display content of the normal symbol display device 15 so as to start the normal symbol variation display. Further, the main control CPU 30a starts measuring the effect time of the normal symbol variation game. Further, the main control CPU 30a causes the normal symbol to be confirmed and stopped based on the fluctuation time set in the normal symbol fluctuation pattern determined in the normal symbol start process. At this time, if the main control CPU 30a determines that the normal hit determination is affirmative, the main control CPU 30a displays the normal hit symbol on the normal symbol display device 15 in a definite stop display. The symbol is displayed on the normal symbol display device 15 with a fixed stop.

  In addition, when an affirmative determination is made in the normal hit determination, the main control CPU 30a opens and closes the open / close blade 12a according to a predetermined operation pattern after the normal symbol variation game is finished (after the normal hit symbol is confirmed and stopped). Grant a game. In the non-variable state, the main control CPU 30a opens and closes the opening / closing blade 12a for the first number of times (one time in the present embodiment) for the first time to open (0.2 seconds in the present embodiment). On the other hand, in the variable speed state, the main control CPU 30a sets the opening / closing blade 12a to the second opening time larger than the first number of times in the second opening time (1.5 seconds in this embodiment) longer than the first opening time. The opening operation is performed the number of times (in this embodiment, three times). By controlling the opening operation of the opening / closing blade 12a with different operation patterns according to the gaming state, the opening time of the opening / closing blade 12a becomes longer during the variable state.

  Next, an update monitoring process executed by the main control CPU 30a for monitoring whether or not an abnormality has occurred in updating the random number values by the random number generation circuits Rs1 and Rs2 will be described. The main control CPU 30a executes an update monitoring process every predetermined control cycle.

  In the update monitoring process, the main control CPU 30a refers to the contents stored in the internal information registers of the update monitoring circuits Ks1 and Ks2, and determines whether or not update abnormality information is set. When the update abnormality information is not set, the main control CPU 30a ends the update monitoring process.

  On the other hand, when the update abnormality information is set, the main control CPU 30a specifies that an abnormality has occurred in updating the random number values by the random number generation circuits Rs1 and Rs2. In this case, the main control CPU 30a outputs to the effect control board 31 (the effect control CPU 31a) an abnormality notification command that can specify that the update abnormality of the random number is notified. Thereafter, the main control CPU 30a ends the update monitoring process. When starting to output the abnormality notification command, the main control CPU 30a continuously outputs the abnormality notification command until the setting of the update abnormality information is canceled.

  Next, various processes executed by the effect control CPU 31a of the effect control board 31 based on the effect control program will be described. When the predetermined control command is input from the main control CPU 30a at a predetermined timing, the effect control CPU 31a executes various processes in accordance with the control command.

Hereinafter, processing performed by the effect control CPU 31a to execute the decorative symbol variation game will be described.
When the special design designation command is input, the effect control CPU 31a determines the symbol combination based on the decorative design to be confirmed and stopped on the production display device 10, based on the final stop design designated by the special design designation command. The effect control CPU 31a determines a jackpot symbol combination when the final stop symbol designated by the special symbol designation command is a jackpot symbol. Further, when the designated final stop symbol is a small hit symbol, the effect control CPU 31a determines a small symbol combination.

  In addition, when the designated final stop symbol is an outlier symbol, the effect control CPU 31a uses a decorative symbol that causes the effect display device 10 to display a fixed stop based on the special symbol variation pattern designated by the variation pattern designation command. Determine the symbol combination. In other words, the effect control CPU 31a determines the combination of symbols of the detachment reach when the designated final stop symbol is a detachment symbol and the variation pattern for the detachment reach effect is designated. In addition, when the designated final stop symbol is an outlier design, and the variation pattern for the outlier effect is designated, the effect control CPU 31a determines the outlier symbol combination.

  Further, when the variation control designation command is input, the effect control CPU 31a starts the variable display of the decorative symbols of all symbol sequences, and controls the display contents of the effect display device 10 so that the decorative symbol variation game is started. The effect control CPU 31a specifies the effect content of the decorative symbol variation game based on the special symbol variation pattern designated by the input variation pattern designation command so that the ornament symbol variation game with the identified effect content is executed. The display content of the effect display device 10 is controlled. Then, the effect control CPU 31a controls the effect display device 10 so that the determined decorative symbols are displayed in a definite stop when the all symbols stop command is input.

  In addition, when the special symbol variation pattern of the variation content accompanied by the pseudo continuous rendering (two or more variation cycles) is designated, the effect control CPU 31a is configured to include a pseudo cycle composed of the number of variation cycles that can be specified from the special symbol variation pattern. The display content of the effect display device 10 is controlled so that the continuous effect is executed. In addition, when the special symbol variation pattern that specifies the execution of the pseudo-continuous rendering is specified, the effect control CPU 31a can select from among the combinations of symbols that are out of place as decorative symbols that are temporarily displayed in the variation cycle other than the last time. Determine a specific symbol combination. The effect control CPU 31a temporarily stops and displays the determined specific symbol combination for each variation cycle except the last.

Next, processing performed by the effect control CPU 31a to notify the update abnormality of the random number value will be described.
When the abnormality control command is input from the main control CPU 30a, the effect control CPU 31a receives update abnormality information (for example, “internal error is occurring” or the like) to notify that an abnormality has occurred in the update of the random number value. The display content of the effect display device 10 is controlled to display an error so as to display a simulated image). The effect control CPU 31a continuously displays the update abnormality information on the effect display device 10 until the input of the abnormality notification command is stopped.

According to this embodiment, the following effects can be obtained.
(1) The main control CPU 30a acquires, from one random number generation circuit, random numbers updated by the random number generation circuit as random numbers used for different types of determinations at different timings. For this reason, in the present embodiment, even when the number of types of determination regarding games is increased, the number of necessary random number generation circuits is suppressed from increasing, and the configuration for generating random numbers is suppressed from becoming complicated. it can.

  (2) Each of the random number generation circuits Rs1 to Rs4 updates the random number value at an update cycle with a time shorter than the shortest time from when the main control CPU 30a acquires one random number value until the next random number value is acquired. . For this reason, in the present embodiment, it is possible to prevent the main control CPU 30a from acquiring the same value as a random number used for different types of determination.

  (3) The main control CPU 30a acquires, from one random number generation circuit, random numbers used for at least some types of determination among a plurality of determinations that can be classified into each system. For this reason, in this embodiment, the random number used for the determination classified into each system | strain can be managed collectively. Therefore, in this embodiment, it is possible to perform random number updating, random number acquisition, and determination using a random number by using one random number generation circuit, and the processing related to determination can be simplified.

  (4) The main control CPU 30a acquires the random number value updated by the first random number generation circuit Rs1 from the first random number generation circuit Rs1 as a random number used for the determination classified into the first system. On the other hand, the main control CPU 30a acquires the random number value updated by the third random number generation circuit Rs3 from the third random number generation circuit Rs3 as a random number used for the determination classified into the third system. Thereby, in this embodiment, even when there are a plurality of random number generation circuits, random numbers used for determination of different systems can be managed together for each system. Therefore, in this embodiment, the process concerning determination regarding a game can be simplified.

  (5) The main control CPU 30a updates the random number generation circuits Rs2 and Rs3 from the random number generation circuits Rs2 and Rs3 that can update the random number values in different modes (in this embodiment, the range of values that the random number values can take). The random value is acquired as a random number used for the determination classified into the third system. Therefore, in this embodiment, the randomness can be improved for the random numbers used for the determination of the third fixed system.

  (6) The main control CPU 30a uses the random number value updated by the third random number generation circuit Rs3 among the random number generation circuits Rs3 and Rs4 for updating the random number value within the same numerical range for the second and third variation pattern distribution. On the other hand, the random number value updated by the fourth random number generation circuit Rs4 is acquired as a random number for fourth variation pattern distribution while being acquired as a random number. As described above, in each of the random number generation circuits Rs3 and Rs4, since the hardware initial value is changed every time the random number value is updated, different random number values can be latched in principle. Therefore, it is possible to acquire different random numbers as the second to fourth variation pattern distribution random numbers.

  (7) Judgment regarding the game is determined from the viewpoint of the magnitude of the influence on the game result (player's profit), whether or not it is determined (first system), hit type determination (second system), and production determination (third system) ) Roughly. Therefore, in the present embodiment, random numbers can be managed collectively from the viewpoint of the effect on the game result, and the process related to the game determination can be simplified.

  (8) When the value is acquired as a random number from each of the random number generation circuits Rs1 and Rs2 that updates the random number value within the 16-bit numerical range, each random number generation circuit Rs3 that updates the random value within the 8-bit numerical range , Rs4, the ratio of the determination result can be set in detail as compared with the case where the value is acquired as a random number. On the other hand, when the value is acquired as a random number from each of the random number generation circuits Rs3 and Rs4 that update the random number value within the 8-bit numerical range, each random number generation circuit Rs1,1 that updates the random value within the 16-bit numerical range. Compared to the case where the value is acquired as a random number from Rs2, the data size of each determination value necessary for determination can be reduced, and the burden on the determination process can be reduced.

  (9) When the update monitoring circuits Ks1 and Ks2 detect that the random number value is not updated normally, the update monitoring circuits Ks1 and Ks2 set update abnormality information indicating an abnormality in updating the random number value in the internal information register. Thereby, in this embodiment, it is possible to detect whether or not the first random number generation circuit Rs1 and the second random number generation circuit Rs2 are operating normally.

In addition, the said embodiment can be actualized in another embodiment (another example) as follows.
The frequency (output cycle) of the input clock signal may be different for each of the random number generation circuits Rs1 to Rs4. In this case, for example, the random number circuit 30d is provided with first to fourth frequency dividing circuits that convert the clock signal generated from the clock oscillator CH to a frequency lower than the oscillation frequency and output the same. The first divider circuit is a first random number generator circuit Rs1, the second divider circuit is a second random number generator circuit Rs2, the third divider circuit is a third random number generator circuit Rs3, and the fourth divider circuit is Each is connected to the fourth random number generation circuit Rs4. Then, by changing the frequency dividing ratio of each frequency dividing circuit, the update cycle for updating the random number value in the random number generating circuit to which each frequency dividing circuit is connected can be made different. Therefore, it can suppress that the random value updated by each random number generation circuit Rs1-Rs4 synchronizes. However, the random number value update cycle (frequency of the clock signal) in each of the random number generation circuits Rs1 to Rs4 is shorter than the shortest time from when the main control CPU 30a acquires one random number value until it acquires the next random number value. Make time.

  The random number circuit 30d may include first to fourth initial value generation circuits that generate hardware initial values separately and set the random number generation circuits Rs1 to Rs4. In this case, the first initial value generation circuit is the first random number generation circuit Rs1, the second initial value generation circuit is the second random number generation circuit Rs2, the third initial value generation circuit is the third random number generation circuit Rs3, and the fourth The initial value generation circuit is connected to the fourth random number generation circuit Rs4. According to this configuration, the random number values updated by the random number generation circuits Rs1 to Rs4 can be made different and synchronized with respect to the input of clock signals having the same frequency.

  In each of the random number generation circuits Rs1 to Rs4, the order of random number values to be updated (random number sequence) may be changed every time the random number values are updated. In this case, the random number circuit 30d is provided with first to fourth order change circuits that change the order of random number values updated by the random number generation circuits Rs1 to Rs4. The first order change circuit is the first random number generation circuit Rs1, the second order change circuit is the second random number generation circuit Rs2, the third order change circuit is the third random number generation circuit Rs3, and the fourth order change circuit is Each is connected to the fourth random number generation circuit Rs4. By changing the order of the random value to be changed, the random number values updated by the random number generation circuits Rs1 to Rs4 can be made different and synchronized with respect to the input of the clock signal having the same frequency.

  The numerical value range (maximum value) of the random number values updated by the random number generation circuits Rs1 to Rs4 may be changeable. In this case, the random number circuit 30d is provided with first to fourth range setting circuits for changing the numerical value range of the random number values updated by the random number generation circuits Rs1 to Rs4. The first range setting circuit is a first random number generation circuit Rs1, the second range setting circuit is a second random number generation circuit Rs2, the third range setting circuit is a third random number generation circuit Rs3, and the fourth range setting circuit is a fourth range setting circuit. Each is connected to a random number generation circuit Rs4. By changing the numerical value range to be changed, the random number values updated by the random number generation circuits Rs1 to Rs4 can be made different and synchronized with respect to the input of the clock signal having the same frequency.

  -The production content of the game effect executed during the special symbol variation game may be changed as appropriate. For example, the specific contents of the super reach effect or the maximum number of variable cycles constituting the pseudo continuous effect may be changed. Further, different game effects may be executed instead of or in addition to the super reach effect and the pseudo continuous effect.

-In the pseudo-continuous production, it is not necessary to stop and display the symbol combination of the decorative symbols with a specific symbol combination.
The variation cycle may be executed once after the variation display of the decorative symbols is started until the decorative symbols of some of the symbol sequences are temporarily displayed.

The determination ratio (determination ratio) of each special symbol variation pattern HP1 to HP50, that is, the distribution mode, may be changed as appropriate.
