Abstract

PROBLEM TO BE SOLVED: To provide a game machine for allowing a player to keep a feeling of hope for the result of a succeeding symbol variable game, by concealing not only whether or not the number of times of a jackpot during a probability variable state reaches an upper limit value but also whether or not the probability variable state is imparted and also allowing the player to guess them.SOLUTION: An integrated control CPU compares the number of times X of the jackpot, to win a probability variable jackpot during the probability variable state, with the upper limit value of the predetermined number of times X of the jackpot, to determine whether or not the number of times X of the jackpot reaches the upper limit value (S230). When it is determined that the number of times X of the jackpot reaches the upper limit value, the integrated control CPU clears the number of times X of the jackpot (S250). The integrated control CPU conceals the number of times X of the jackpot, and also conceals whether or not the probability variable state is imparted.

Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine in which an upper limit value is set for the number of jackpots that is a jackpot during a probability variation state.

  2. Description of the Related Art Conventionally, a gaming machine having a function (so-called limiter function) for limiting the number of big hits (so-called consecutive times) in a probability variation state has been proposed (see, for example, Patent Document 1). In Patent Document 1, a plurality of limiter times (upper limit value of the number of big hits) are provided, and an effect that suggests the number of limiters is performed during the big hit game state, thereby giving the player whether or not the number of big hits has reached the limiter number. The technique to make it guess is described.

JP 2008-29624 A (Claim 1, FIG. 10, etc.)

  However, in the prior art described in Patent Document 1, it is determined whether it is a big hit in a probability variation state (so-called probable big hit) or a big hit in a normal state to which a probability variation state is not given (so-called non-probable big hit). It can be easily discriminated. That is, if it is a probable big hit, the number of limiters can be estimated during the big hit gaming state, but if it is determined that it is a non-probable big hit, it will be found that it will be in the normal state after the big hit gaming state. Expectation for the results will be reduced.

  The present invention has been made in view of the above problems, and its purpose is to conceal not only whether the number of jackpots in the probability variation state has reached the upper limit value, but also whether the probability variation state is given. Accordingly, it is an object of the present invention to provide a gaming machine that can maintain a sense of expectation for the result of the next symbol variation game by causing the player to make a guess.

  In order to solve the above-mentioned problems, the invention according to claim 1 (means 1) is triggered by a winning prize device arranged at a predetermined position on the game board surface and a winning of a game ball to the starting prize device. As follows: a symbol display unit for displaying a symbol variation game for changing symbols, a closed state that does not accept a game ball, and a winning device that can be switched to an open state that easily accepts a game ball, and a game that controls the entire gaming machine A game machine comprising a control means, wherein the game control means is a jackpot determining means for determining whether or not the result of the symbol variation game is a jackpot, and the determination result by the jackpot determining means is a jackpot In addition, when the determination result by the big hit game state granting means for giving the big hit gaming state that the big winning device is in the open state and the big hit determination means becomes a big hit, the symbol variation game The probability variation state provision determining means for determining whether or not a probability variation state in which the probability that the jackpot is derived fluctuates with high probability is provided, and the probability variation state is imparted by the probability variation state provision determination means. A probability variation state giving means for giving the probability variation state after completion of the jackpot gaming state, and a jackpot number calculation means for calculating the number of jackpots that became a probability variation big hit during the probability variation state; Whether or not the big hit number calculated by the big hit number calculating means reaches the upper limit value by comparing the big hit number calculated by the big hit number calculating means with a preset upper limit value of the big hit number It is determined that the big hit count calculated by the big hit count determination means and the big hit count calculation means has reached the upper limit value. The big hit number clearing means for clearing the big hit number calculated by the big hit number calculating means, and the probability when the big hit number calculated by the big hit number calculating means has reached the upper limit value. A gaming machine comprising: a probability variation state addition ending unit that terminates the provision of a variation state; and a concealment unit that conceals the number of jackpots and conceals whether or not the probability variation state is provided. The gist.

  Therefore, according to the first aspect of the invention, by concealing the number of jackpots in the probability variation state by the concealment means, the player can obtain information “whether the number of jackpots has reached the upper limit value? Can enjoy the game nature of guessing the information. Further, by concealing whether or not the probability variation state is given by the concealment means, the player can enjoy the game characteristic of also guessing the information “whether or not the probability variation state is given?”. In other words, since the number of jackpots reaches the upper limit and the provision of the probability variation state is terminated, or it is not known that the jackpot is not in the probability variation state, the player seems to play with a sense of tension. As a result, the expectation for the result of the next symbol variation game is sustained.

  Here, as a suitable symbol display unit in the present invention, an electric symbol display unit such as a liquid crystal type, a dot matrix type, an electroluminescence element type, a seven segment type, a drum type, a belt type, etc. A mechanical symbol display unit and the like can be mentioned, and it is particularly preferable to use an electric symbol display unit, and it is particularly preferable to use a liquid crystal type among the electric symbol display units. In this way, it becomes easy to execute a complex presentation in the symbol variation game.

  Further, the grand prize winning device can be switched between a closed state in which no game ball is received and an open state in which the game ball is easily received. In addition, as a specific example of the closed state, for example, a state where the big prize opening door of the big prize winning device is completely closed can be cited. On the other hand, as a specific example of the open state, for example, a state in which the grand prize opening door is completely opened can be cited.

  The upper limit value of the number of big hits is not particularly limited, but is preferably 3 or more and 10 or less, for example. If the upper limit value is greater than 10, the number of big hits is difficult to reach the upper limit value, so that the big hits in the probability fluctuation state are continued for a long period of time, and the gambling is too much. On the other hand, when the upper limit value is less than 3, the number of jackpots easily reaches the upper limit value, so that the big hit in the probability variation state ends immediately, and the expectation for the probability variation state decreases.

  The invention described in claim 2 (means 2) is the jackpot count clearing means according to claim 1, wherein the jackpot number clearing means determines that the probability fluctuation state is not given by the probability fluctuation state giving judgment means. Regardless of whether or not the big hit number calculated by the calculation means has reached the upper limit value, the big hit number calculated by the big hit number calculation means is cleared, while the probability fluctuation state giving determination means determines the probability fluctuation state. If the jackpot number calculated by the jackpot number calculating means reaches the upper limit when the jackpot number is calculated, the big hit number calculated by the jackpot number calculating means is cleared. And

  Therefore, according to the invention of claim 2, when the probability variation state is not given, the number of big hits is cleared regardless of whether or not the number of big hits has reached the upper limit value. Whether or not the value has been reached can be securely concealed. Moreover, since the number of jackpots may be cleared regardless of whether or not the probability variation state is given, it is possible to securely conceal whether or not the probability variation state is given.

  The invention according to claim 3 (means 3) is characterized in that, in claim 1 or 2, the concealment means sets a probability variation concealment mode for concealing that the probability variation state is given to the game effect in the symbol variation game. An effect mode setting means for setting as an effect mode, and an effect symbol determining means for determining a plurality of types of effect symbols as the symbols, wherein the effect mode setting means, when the result of the symbol variation game is a big hit, Regardless of whether or not the probability variation state is imparted by the probability variation state imparting means, the same effect mode is set as the effect mode in the symbol variation game after the end of the big hit gaming state, and the effect symbol determination means is The gist is to determine, as the effect symbol, a symbol that cannot be determined whether or not the probability variation state is present.

  Therefore, according to the third aspect of the present invention, the same effect mode is set regardless of whether or not the probability variation state is given, and the design that cannot determine whether or not the probability variation state is present. Since it is determined as the effect design, it can be more reliably concealed whether or not the probability variation state is given.

  The production mode is a probability change concealment mode for concealing that the probability variation state is given. The effect mode setting means may set one kind of effect mode as an effect mode in the symbol variation game after the end of the big hit gaming state, or a plurality of types of effect modes after the end of the big hit gaming state. It may be set as an effect mode. Here, examples of the plurality of types of effect modes include a first probability variation concealment mode and a second probability variation concealment mode having a lower probability of being given a probability variation state than the first probability variation concealment mode. In this case, since there are a plurality of effect modes having different profits, the player has a great expectation for the result of the next symbol variation game, and the interest of the game is improved.

  The invention according to claim 4 (means 4) is the game control means according to claim 3, wherein the game control means includes the jackpot determination means, the jackpot game state provision means, the probability variation state provision determination means, and the probability variation state provision means. A main control means having functions as the jackpot number calculation means, the jackpot number determination means, the jackpot number clearing means, and the probability variation state giving end means; and the concealment means electrically connected to the main control means Sub-control means having a function as: and the main control means, after the end of the jackpot gaming state, the variable time shortening state giving means for giving a variable time shortening state for shortening the variation time in the symbol variation game The variation time shortening state providing means comprises the same number of times regardless of whether or not the probability variation state is provided by the probability variation state providing means. Until the symbol variation game is executed, the variation time reduction state is continuously applied, and the effect symbol determination unit determines whether the probability variation state is imparted by the probability variation state provision unit or not. Regardless, the gist is that the effect symbol can be determined from all of the plural types of effect symbols.

  Therefore, according to the fourth aspect of the present invention, the provision of the variation time shortening state is continued until the same number of symbol variation games are executed regardless of whether or not the probability variation state is imparted. At the same time, since the effect symbols are determined from all of the plurality of types of effect symbols, it is possible to more reliably conceal whether or not the probability variation state is given.

  Note that the number of executions of the symbol variation game in which the variation time shortening state providing unit continues to provide the variation time shortening state is not particularly limited, and may be, for example, zero. That is, the variation time shortening state providing means may not provide the variation time shortening state after the big hit gaming state is completed.

  The gist of the invention according to claim 5 (means 5) is that, in any one of claims 1 to 4, a plurality of upper limit values of the number of jackpots are set.

  For example, if only one upper limit value is set for the number of jackpots in the probability variation state, the player will notice that the number of jackpots does not increase beyond a certain value when playing for a long time. You may know how many values there are. Therefore, in the invention described in claim 5, a plurality of upper limit values of the number of big hits are set. As a result, even if the player plays a game for a long time, the upper limit value fluctuates in a complicated manner, and it is difficult to understand how many upper limit values are. Therefore, the pleasure of guessing whether or not the number of big hits has reached the upper limit is increased.

  In addition, the number of upper limit values of the number of big hits is not particularly limited as long as it is plural, but for example, it is preferably 3 or more and 5 or less. That is, when the number of upper limit values is 3 or more, the upper limit value varies more complicatedly when a player plays a game for a long time, and therefore it becomes more difficult to understand how many upper limit values are. On the other hand, if the number of upper limit values is 5 or less, an increase in the capacity of data indicating the upper limit value can be suppressed, and the burden on the storage means for storing the upper limit value can be reduced.

  Further, the upper limit value of the number of jackpots may be varied depending on the type of effect design. For example, the possibility that the upper limit value of the number of big hits will increase as the number of effect symbols increases. However, it is preferable that the number of production symbols is different from the upper limit value. For example, if the upper limit value is set to 7 when the winning symbol “7, 7, 7” is a big hit, there is a high possibility that the upper limit value will be known by looking at the producing symbol. The meaning of concealing will be reduced.

  As described in detail above, according to the first to fifth aspects of the present invention, not only whether or not the number of jackpots in the probability variation state has reached the upper limit value, but also whether or not the probability variation state is given. By concealing and letting the player guess, it is possible to provide a gaming machine that can maintain a sense of expectation for the result of the next symbol variation game. In particular, according to the third aspect of the present invention, it can be more reliably concealed whether or not the probability variation state is given.

The left speaker 17a and the right speaker 17b are mounted on the back side of the front frame 14, and a plurality of sound emitting holes are formed at locations corresponding to the left speaker 17a and the right speaker 17b on the front side of the front frame 14.

  Further, a lower ball tray 18 is assembled to be openable and closable below the front frame 14 on the front side of the middle frame 12. On the right side of the lower ball tray 18 is mounted an operation handle 19 that is turned by the player when the game ball is launched. Further, on the left side of the lower ball tray 18, an ashtray 20, a woofer speaker 17c, and the like are disposed. Note that the woofer speaker 17c is used to execute sound effects for outputting various sounds, and is attached to the middle frame 12.

  As shown in FIGS. 1 and 2, an inner rail 41 a and an outer rail 41 b are laid in a substantially circular shape on the game board surface 13 a of the game board 13. A game ball launched when the operation handle 19 is operated passes through a launch path generated between the inner rail 41a and the outer rail 41b. In addition, a plurality of game nails 81 and the like projecting from almost the entire area of the game board surface 13a are disposed in the game area, which is the inner area of the inner rail 41a and the outer rail 41b. The game nail 81 is adapted to change the direction of the game ball flowing down in the game area.

  In addition, a frame-shaped center accessory 60 having a rectangular opening is attached to a substantially central portion of the game board 13 on the game board surface 13a. An effect symbol display device 61 which is a “symbol display unit” provided with a visible display unit (display screen) is disposed on the back side of the center accessory 60. The effect symbol display device 61 of the present embodiment is a liquid crystal type, but may be a dot matrix type, electroluminescence element type, or seven segment type effect symbol display device. In the effect symbol display device 61, a game effect (display effect) based on a fluctuating image (or image display) is performed. Then, in the effect symbol display device 61, an effect symbol change game is performed in which a plurality of types of effect symbols E1 are changed in three columns in relation to the display effect. The production symbol E1 is a symbol indicating five numbers “0” to “4”.

  As shown in FIGS. 1 and 2, a start winning device 21 having a start winning port 21a is disposed in a lower region of the center accessory 60 (production symbol display device 61) on the game board surface 13a. ing. The start winning device 21 is integrally configured with an ordinary electric accessory comprising a pair of blade members 21b. The pair of blade members 21b are configured to open and close by the excitation action of the ordinary electric accessory solenoid SOL1 (see FIG. 3). In addition, a start opening switch SE1 (see FIG. 3) for detecting a game ball that has entered the start winning opening 21a is provided behind the start winning apparatus 21. The start port switch SE1 is turned on when a game ball won in the start winning device 21 is detected, and outputs a winning signal. On the other hand, the start port switch SE1 is turned off when no game ball is detected, and no winning signal is output. When the winning signal is output, a special symbol variation game is performed by the special symbol display device 51, and an effect symbol variation game is performed by the effect symbol display device 61 in relation to the special symbol variation game, A predetermined number (three in this embodiment) of prize balls is paid out.

  As shown in FIG. 1, a large winning device 23 is disposed in a lower region of the start winning device 21 on the game board surface 13a. The special winning device 23 is integrally formed with a special electric accessory consisting of a special winning opening door 23a. The special winning opening door 23a can be switched between a closed state in which the game ball is not received and an open state in which the game ball is easily received by the exciting action of the special winning solenoid SOL2 (see FIG. 3). In the present embodiment, the “closed state” means a state in which the big prize opening door 23a is completely closed, and the “open state” means a state in which the big prize opening door 23a is completely opened. In addition, a count switch SE2 (see FIG. 3) for detecting a winning game ball is provided in the back of the big winning device 23. When a game ball is detected by the count switch SE2, a predetermined number (10 in this embodiment) of prize balls is paid out.

  As shown in FIGS. 1 and 2, a gate 25 having a function of detecting the passage of a game ball is provided in the left side area of the center accessory 60 (production symbol display device 61) on the game board surface 13a. . Behind the gate 25 is provided a gate switch SE3 (see FIG. 3) for detecting the passed game ball. Note that, when a game ball is detected by the gate switch SE3, a random number is acquired, and the ordinary electric accessory solenoid SOL1 is driven based on a result of determining whether or not the acquired random number is a predetermined random value. . Since the pair of blade members 21b are opened by such determination (hit determination), it becomes easy for the game ball to win the start winning device 21.

  Further, a special symbol display device 51 which is a “symbol display unit” having a visible display unit is disposed at the lower left of the center accessory 60. The special symbol display device 51 displays a special symbol variation game that fluctuates the special symbol B1 in response to the winning of the game ball to the start winning device 21, and the result of the special symbol variation game is a display result of a big win or a loss. Is displayed. For example, when the result of the special symbol variation game is a big hit, at the end of the special symbol variation game, symbols representing ten numbers “0” to “9” are displayed as the special symbol B1. Further, when the result of the special symbol variation game is lost, at the end of the special symbol variation game, a symbol “-” indicating a loss is displayed as the special symbol B1. The special symbol B1 is a symbol (a symbol that is not a letter or a number) that does not make sense in appearance (see FIG. 2).

  Here, the special symbol B1 displayed in the case of a big hit consists of a probability variation symbol and a non-probability variation symbol. The probability variation symbol is a symbol that triggers the start of a probability variation state in which the probability that a jackpot is derived in the special symbol variation game varies with a high probability. The non-probable variation symbol is a symbol that is in a normal state that does not trigger the probability variation state. The probability variation symbol of this embodiment is a special symbol B1 indicating the numbers “0”, “1”, “2”, “3”. On the other hand, the non-probable variable symbol of this embodiment is a special symbol B1 indicating the numbers “4”, “5”, “6”, “7”, “8”, “9”.

  Furthermore, in this embodiment, the effect symbol change game by the effect symbol display device 61 is performed in accordance with the special symbol change game in the special symbol display device 51. Specifically, the effect symbol variation game is started almost simultaneously with the start of the special symbol variation game, and the result of the effect symbol variation game is displayed almost simultaneously with the end of the special symbol variation game (the display result of jackpot or lose) is displayed. It has become so. In the present embodiment, the effect symbol variation game performed by the effect symbol display device 61 and the special symbol variation game performed by the special symbol display device 51 are referred to as “symbol variation game”.

  As shown in FIG. 2 and the like, a special symbol holding display device C is disposed below the special symbol display device 51. The special symbol hold display device C is constituted by a plurality of (four) light emitting means including a first hold lamp C1, a second hold lamp C2, a third hold lamp C3, and a fourth hold lamp C4. The holding lamps C <b> 1 to C <b> 4 are turned on when there is a game ball (starting holding ball) stored in response to winning at the start winning device 21, and are turned off when there is no starting holding ball. Each of the holding lamps C1 to C4 is for indicating the number of starting holding balls (the number of starting holding balls). For example, when there are three start holding balls, three holding lamps C1 to C3 are lit.

  Here, “the number of reserved starting balls” is the number of game balls won in the start winning device 21 during the fluctuation of the special symbol B1 (production symbol E1) within a predetermined maximum value (4 in the present embodiment). The stored value. The number of starting reserved balls is “+1” by winning a game ball to the starting winning device 21 and “−1” by starting the symbol variation game.

  As shown in FIGS. 1 and 2, a normal symbol display device 53 having a visible display unit is disposed on the lower right side of the center accessory 60. In this normal symbol display device 53, a normal symbol variation game that fluctuates the normal symbol G1 is executed in response to the passing of the game ball to the gate 25, and the normal symbol variation result is displayed as a result of the random symbol lottery. The symbol G1 is stopped and displayed. In addition, the normal symbol G1 of the present embodiment is of two types: a winning symbol “◯” or a lost symbol “X”. When the winning symbol is derived (when the normal symbol variation game is won), the normal electric accessory solenoid SOL1 is driven for a predetermined time, and the pair of blade members 21b are opened.

  As shown in FIG. 2 and the like, a normal symbol holding display device F is disposed below the normal symbol display device 53. The normal symbol hold display device F is constituted by a plurality of (four) light emitting means including a first hold lamp F1, a second hold lamp F2, a third hold lamp F3, and a fourth hold lamp F4. The holding lamps F <b> 1 to F <b> 4 are turned on when there is a game ball (ordinary symbol holding ball) stored with the passage of the gate 25 as an opportunity, and turned off when there is no normal symbol holding ball. Each of the holding lamps F1 to F4 is for indicating the number of normal symbol holding balls (the number of normal symbol holding balls). For example, when there are two normal symbol holding balls, two holding lamps F1 and F2 are lit.

  Here, the “ordinary symbol reserved ball number” is a value stored in a range of a predetermined maximum value (4 in the present embodiment), the number of game balls that have passed through the gate 25. The normal symbol holding ball number is “+1” when the game ball passes to the gate 25 and is “−1” when the normal symbol variation game is started.

(2) Electrical Configuration of Pachinko Machine 10 As shown in FIGS. 3 and 4, the pachinko machine 10 includes a main control board 31, an overall control board 32, a display control board 33, and an audio / lamp control board 34. Yes. An overall control board 32 is electrically connected to the main control board 31, and a display control board 33 and an audio / lamp control board 34 are electrically connected to the overall control board 32.

(2-1) Electrical Configuration of Main Control Board 31 The main control board 31 includes a “game control means” that controls the entire pachinko machine 10 and a main CPU 31a that is a “main control means”. A start port switch SE1, a count switch SE2, and a gate switch SE3 are connected to the main CPU 31a. In addition, a special symbol display device 51, a special symbol hold display device C, a normal symbol display device 53, and a normal symbol hold display device F are connected to the main CPU 31a. Further, the main CPU 31a is connected to a normal electric accessory solenoid SOL1 and a special prize opening solenoid SOL2.

  As shown in FIG. 4, a main ROM 31b and a main RAM 31c are electrically connected to the main CPU 31a. The main CPU 31a updates the values of various random numbers such as jackpot determination random numbers, jackpot symbol random numbers, reach determination random numbers, variation pattern distribution random numbers and the like used for various lotteries relating to the symbol variation game at predetermined intervals. Then, the main CPU 31a sets the updated value in the random number storage area of the main RAM 31c and rewrites the value before the update. Various flags that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set) in the flag storage area of the main RAM 31c. In the timer storage area of the main RAM 31c, various timers that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set). The reserved ball storage area of the main RAM 31c stores the start reserved ball and the normal symbol reserved ball.

  Note that the big hit determination random number is a random number used when determining whether or not the symbol variation game is a big hit (when determining the big hit). The jackpot symbol random number is a random number used when determining the special symbol B1 when the result of the symbol variation game is a jackpot. The reach determination random number is a random number used when deciding whether or not to execute the reach effect when the result of the symbol variation game is lost (at the time of reach determination). The variation pattern distribution random number is a random number used when determining the variation pattern for specifying the effect time and effect contents of the game effect in the symbol variation game.

  In addition, in a predetermined area of the main RAM 31c shown in FIG. 4, the value of the big hit number X (that is, the number of consecutive games) that is a big hit in the probability change state during the probability change state is stored. More specifically, the main RAM 31c temporarily stores the number of big hits X in the probability variation state as the big hit number X. In the main ROM 31b, an upper limit value ("3" in the present embodiment) of the number of big hits X is set (stored) in advance.

  Further, the main ROM 31b stores a variation pattern distribution table in which variation patterns for special symbol variation games (production symbol variation games) are distributed. In each variation pattern, the symbols in all the columns displayed on the effect symbol display device 61 (the effect symbol E1) start changing (the effect symbol variation game is started), and the symbols in all the columns are stopped (the effect symbol variation game is displayed). This is for specifying the production time and the content of the production effect (display effect, light emission effect, sound effect) until (end). Each variation pattern is classified into a variation pattern for a loss effect, a variation pattern for a loss reach effect, and a variation pattern for a jackpot effect. Further, the variation pattern distribution random number values (100 integers from 0 to 99 in this embodiment) are allocated to the variation pattern. It should be noted that the variation pattern for the losing effect indicates a pattern serving as a base of the losing effect that displays the symbol combination of the losing without passing the reach effect. The variation pattern for the lost reach production shows the pattern that is the base of the lost reach production that displays the lost symbol combination (the combination where the middle symbol stops at a different symbol from the left and right symbols) after reaching the reach effect. ing. The variation pattern for the jackpot effect indicates the pattern that is the base of the jackpot effect that displays the jackpot symbol combination (the symbol symbol combination that stops at the same symbol as the left symbol and the right symbol) after reaching the reach effect. . The reach effect refers to an effect in which, after the middle symbol is changed in a state where the left symbol and the right symbol are stopped with the same symbol, the symbol combination is stopped and the symbol combination is derived. In addition, the production time (fluctuation time) of the lost production, the lost reach production, and the jackpot production is different for each variation pattern.

  The main ROM 31b shown in FIG. 4 stores a symbol number table.

It is associated.

  A special symbol type flag table (see FIG. 5A) is stored in the main ROM 31b shown in FIG. In the special symbol type flag table, special symbol type flags 00H, 01H, 02H, 03H, 04H, 05H, 06H, 07H, 08H, 09H for identifying the symbol types for symbol numbers 0 to 4 are listed. .

Symbol number 3 is associated with special symbol type flags 03H and 08H, and symbol number 4 is associated with special symbol type flags 04H and 09H.

  The main ROM 31b stores a special symbol probability changing preliminary flag table (see FIG. 5B). In the special symbol probability changing preliminary flag table, special symbol probability changing preliminary flags 00H and 01H for instructing the provision of the probability variation state after the end of the big hit gaming state are listed. The special symbol probability change preliminary flag 00H is associated with special symbol type flags 04H, 05H, 06H, 07H, 08H, 09H, and the special symbol probability change preliminary flag 01H is associated with special symbol type flags 00H, 01H, 02H, 03H. It has been. Note that “01H” is set as a special symbol probability change preliminary flag when an instruction to give a probability variation state is set, and “00H” is set as a special symbol probability change preliminary flag when an instruction to give a probability change state is not given. . In addition, when “01H” is set as the special symbol probability change preliminary flag, in addition to the provision of the probability variation state, the provision of the variation time shortening state for shortening the variation time in the special symbol variation game is also instructed. ing.

  Further, the main ROM 31b shown in FIG. 4 stores a variable time shortening reserve flag table (see FIG. 5C). The variable time shortening preliminary flag table includes variable time shortening preliminary flags 00H and 01H for instructing the provision of the variable time shortening state after the end of the big hit gaming state. The special symbol type flags 00H, 01H, 02H, 03H are associated with the variable time reduction reserve flag 00H, and the special symbol type flags 04H, 05H, 06H, 07H, 08H, 09H are associated with the variable time reduction preliminary flag 01H. It has been. Note that “01H” is set as the variable time shortening preliminary flag when instructing the provision of the variable time shortening state, and “00H” is set as the variable time shortening preliminary flag when not giving the provision of the variable time shortening state. Is done.

  Next, various processes related to the special symbol variation game executed by the main CPU 31a shown in FIG. 3 and FIG. 4 (such as jackpot determination, reach determination, jackpot symbol, lose symbol, variation pattern determination, etc.) will be described. The main ROM 31b includes programs used for the various processes described above (a jackpot determination program, a jackpot gaming state grant program, a probability variation state assignment determination program, a probability variation state assignment program, a jackpot count calculation program, a jackpot count determination program, a jackpot The number-of-times clearing program, the probability variation state giving end program, and the variation time shortening state giving program) are stored.

  First, the main CPU 31a is triggered by the establishment of the start winning condition (output of a winning signal from the start port switch SE1), and the value of the jackpot determination random number and the jackpot symbol that are extracted by random number lottery and updated at predetermined intervals. The random number value is acquired from the main RAM 31c, and the acquired value is stored (stored) in the random number storage area of the main RAM 31c.

  The big hit determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “big hit determination means”. That is, the main CPU 31a determines whether or not the result of the special symbol variation game is a big hit. More specifically, the main CPU 31a compares the jackpot determination random number stored in the random number storage area of the main RAM 31c with the jackpot determination value stored in the main ROM 31b immediately before the start of the symbol variation game. A big hit determination (hit lottery) is performed to determine whether or not the variable game is successful. In the present embodiment, the numerical value that can be taken as the jackpot determination random number is set to 0 to 599 (all 600 integers). Then, the main CPU 31a uses the two jackpot determination values among the numbers that can be taken as the jackpot determination random number, and determines the jackpot determination by setting the lottery probability of the jackpot to 2/600 (= 1/300).

  When the determination result of the big hit determination is negative (when the value of the big hit determination random number does not match the big hit determination value), the main CPU 31a shown in FIG. 3 and FIG. 4 determines the lost gaming state. In the lost game state, the big prize device 23 is maintained in the closed state, which is disadvantageous to the player. Further, the main CPU 31a compares the reach determination random number value read from the main RAM 31c with the reach determination value stored in the main ROM 31b, and determines whether or not to execute the lose reach. When the determination result of reach determination is affirmative (the value of the reach determination random number and the reach determination value match), the main CPU 31a determines the loss reach. Then, the main CPU 31a reads the fluctuation pattern distribution random number value from the main RAM 31c, and determines the fluctuation pattern for the lost reach effect based on the value.

  Further, when the determination result of reach determination is negative (the reach determination random number value and the reach determination value do not match), the main CPU 31a shown in FIGS. 3 and 4 determines a loss (a loss without a reach). The main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and determines the variation pattern for the loss effect based on the value.

  On the other hand, if the determination result of the big hit determination is affirmative (the value of the big hit determination random number matches the big hit determination value), the main CPU 31a determines the big hit. The main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and determines the variation pattern for the big hit effect based on the value.

  When the determination result by the big hit determination is lost reach or lost, the main CPU 31a determines the symbol “-” which is a lost symbol as the special symbol B1. Further, when the determination result by the jackpot determination is a jackpot, the main CPU 31a determines the special symbol B1 related to the stop symbol (effect symbol E1) derived in the effect symbol variation game on the effect symbol display device 61. Specifically, the main CPU 31a determines a special symbol B1 indicating any one of “0” to “9” based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM 31c. . More specifically, the main CPU 31a selects a symbol number specified based on the value of the jackpot symbol for random numbers from the symbol number table, and determines the special symbol B1 with reference to the selected symbol number. For example, if the jackpot symbol random number is “0” or “5”, the symbol number 0 is selected. If the jackpot symbol random number is “2” or “7”, the symbol number “2” is selected. Then, the main CPU 31a stores a value (symbol number value) indicating the determined special symbol B1 in the main RAM 31c.

  The probability variation state provision determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “probability variation state provision determination means”. That is, the main CPU 31a determines whether or not the probability variation state is given when the determination result by the big hit determination is a big hit. More specifically, the main CPU 31a determines the special symbol type flags 00H, 01H, 02H, 03H, and the like from the special symbol type flag table (see FIG. 5A) based on the value of the symbol number stored in the main RAM 31c. One of 04H is selected, and the selected special symbol type flag is stored in the flag storage area of the main RAM 31c. Next, the main CPU 31a selects a special symbol probability change reserve flag from the special symbol probability change reserve flag table (see FIG. 5B) based on the special symbol type flag stored in the main RAM 31c, and selects the selected special symbol probability change. The reserve flag is stored in the flag storage area of the main RAM 31c. For example, when the special symbol type flag is any one of “00H”, “01H”, “02H”, and “03H”, the main CPU 31a selects the special symbol probability change preliminary flag 01H and is given a probability variation state. Is determined. On the other hand, when the special symbol type flag is “04H”, the main CPU 31a selects the special symbol probability variation reserve flag 00H and determines that the probability variation state is not given. That is, in this embodiment, the probability that the probability variation state is given is 80%.

  The probability variation state providing program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “probability variation state providing means”. That is, when it is determined that the probability variation state is to be imparted, the main CPU 31a imparts the probability variation state in a special symbol variation game that is started after the end of the jackpot gaming state. More specifically, when the value of the special symbol probability changing reserve flag is “01H”, the main CPU 31a starts to give the probability variation state after the end of the big hit gaming state. In addition, when the provision of the probability variation state is started, the main CPU 31a uses the 20 jackpot determination values among the numbers that can be taken by the jackpot determination random number, and sets the jackpot lottery probability to 20/600 (= 30). A big hit judgment is performed as 1). That is, the number of jackpot determination values in the probability variation state is 10 times that in the probability variation state.

  The variation time shortening state providing program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “variation time shortening state providing means”. That is, the main CPU 31a gives a variation time shortening state in the special symbol variation game started after the end of the big hit gaming state. Specifically, the main CPU 31a selects and selects the variable time shortening preliminary flag from the variable time shortening preliminary flag table (see FIG. 5C) based on the special symbol type flag stored in the main RAM 31c. The variable time shortening reserve flag is stored in the flag storage area of the main RAM 31c. For example, when the special symbol type flag is “04H”, the main CPU 31a selects the variable time shortening reserve flag 01H, and starts giving the variable time shortening state after the big hit gaming state. On the other hand, when the special symbol type flag is any one of “00H”, “01H”, “02H”, and “03H”, the main CPU 31a selects the variable time shortening preliminary flag 00H. However, when the special symbol type flag is any one of “00H”, “01H”, “02H”, and “03H”, a special instruction that instructs the provision of the variation time reduction state in addition to the provision of the probability variation state The symbol probability change preliminary flag 01H is selected. Therefore, also in this case, after the big hit gaming state is finished, provision of the variable time shortening state is started. That is, in the present embodiment, the variation time shortening state is provided regardless of whether the probability variation state is provided. Therefore, in this embodiment, the probability that the variation time reduction state is given is 100%.

  The big hit count calculation program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “big hit count calculation means”. That is, the main CPU 31a calculates the big hit number X stored in the main RAM 31c. Specifically, the main CPU 31a determines that the determined variation pattern is a variation pattern for a big hit effect, and the value of the special symbol probability variation preliminary flag stored in the flag storage area of the main RAM 31c is “01H”. In addition, 1 is added to the number X of big hits.

  The big hit number determination program is a program for causing the main CPU 31a to function as “big hit number determination means”. That is, the main CPU 31a compares the big hit number X stored in the main RAM 31c with the upper limit value “3” of the big hit number X stored in the main ROM 31b, so that the big hit number X has reached the upper limit value. It is determined whether or not. In this embodiment, when the big hit number X is larger than the upper limit value, it is determined that the big hit number X has reached the upper limit value.

  The big hit number clearing program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “big hit number clearing means”. That is, when the main CPU 31a determines that the probability variation state is given (that is, when the value of the special symbol probability changing preliminary flag stored in the main RAM 31c is “01H”), the number of big hits X is the upper limit. If it is determined that the value has been reached, the big hit count X is cleared (set to 0). When it is determined that the probability variation state is not given (that is, when the value of the special symbol probability changing reserve flag stored in the main RAM 31c is “00H”), the main CPU 31a sets the big hit count X to the upper limit value. Regardless of whether or not it has been reached, the number X of jackpots is cleared.

  The probability variation state provision end program has a function of the main CPU 31a as “probability variation state provision end means”. That is, the main CPU 31a ends the provision of the probability variation state when it is determined that the number of big hits X has reached the upper limit. Specifically, first, the main CPU 31a adds “+ 05H” to the value of the special symbol type flag stored in the main RAM 31c. As a result, if the special symbol type flag 00H is stored in the main RAM 31c, the special symbol type flag is “05H”. When the special symbol type flag 01H is stored, the special symbol type flag is “06H”, and when the special symbol type flag 02H is stored, the special symbol type flag is “07H”. When the type flag 03H is stored, the special symbol type flag is “08H”, and when the special symbol type flag 04H is stored, the special symbol type flag is “09H”. The main CPU 31a stores the special symbol type flag in the flag storage area of the main RAM 31c.

  Next, the main CPU 31a shown in FIGS. 3 and 4 sets the special symbol probability changing reserve flag from the special symbol probability changing reserve flag table (see FIG. 5B) based on the special symbol type flag stored in the main RAM 31c. The selected special symbol probability changing preliminary flag is stored in the flag storage area of the main RAM 31c. Specifically, regardless of whether the special symbol type flag is “05H”, “06H”, “07H”, “08H”, or “09H”, the main CPU 31a selects the special symbol probability change preliminary flag 00H. However, the provision of the probability variation state is terminated after the end of the big hit gaming state. That is, the probability that the probability variation state is given when the big hit count X reaches the upper limit is 0%.

  Further, the main CPU 31a selects a variation time shortening reserve flag from the variation time shortening reserve flag table (see FIG. 5C) based on the special symbol type flag stored in the main RAM 31c, and selects the selected variation time shortening reserve. The flag is stored in the flag storage area of the main RAM 31c. Specifically, regardless of whether the special symbol type flag is “05H”, “06H”, “07H”, “08H”, or “09H”, the main CPU 31a selects the variable time shortening reserve flag 01H. Then, after the big hit gaming state is finished, the provision of the variable time shortening state is started. That is, when the big hit count X reaches the upper limit, the probability that the variation time shortening state is given is 100%.

  Further, the main CPU 31a shown in FIG. 3 and FIG. 4 performs control to display the special symbol B1 on the special symbol display device 51. More specifically, when the main CPU 31a determines the special symbol B1 and the variation pattern, the main CPU 31a sets (stores) the variation time associated with each variation pattern as a special symbol timer in the timer storage area of the main RAM 31c. 51 starts the change of the special symbol B1.

  Further, when the main CPU 31a instructs the overall control CPU 32a of the overall control board 32 to perform control, a control command or the like is used as a control signal (8-bit signal), and the signal is predetermined via the output port 35 and the output buffer 36. Output at the timing. Specifically, the main CPU 31a first generates a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation, and sets it as a control command (stored in the main RAM 31c). Then, the control command set here is output in the subsequent output processing. Next, the main CPU 31a sets (stores in the main RAM 31c) a special symbol designation command that designates the special symbol B1 as a control command. Then, the control command set here is output in the subsequent output processing. In addition, the main CPU 31a subtracts the special symbol timer set at the start of fluctuation every interrupt (4 ms). When the special symbol timer reaches 0 ms, the main CPU 31a sets (outputs) a symbol stop command for instructing the stop of the special symbol B1 and the effect symbol E1 as a control command.

  The main CPU 31a shown in FIGS. 3 and 4 reads a read signal (INT signal or an instruction signal) to instruct the overall control board 32 to read a control command constituting the control signal in accordance with the output timing of the control signal. , The strobe signal) is output via the output port 35 and the output buffer 36.

  The big hit game state giving program is a program for causing the main CPU 31a to function as “big hit game state giving means”. That is, the main CPU 31a gives a big hit gaming state in which the big winning device 23 is in an open state when the result of the big hit determination is a big hit. In the big hit gaming state, one opening effect, 15 round effects, and one ending effect are executed. The opening effect is executed when the big winning device 23 is in the closed state and when the big hit gaming state is started. Each round effect is executed when the special winning device 23 is switched from the closed state to the open state by the exciting action of the special winning opening solenoid SOL2. The round effect per time is executed between the time when the special winning device 23 is switched to the open state and the switch to the closed state. In addition, the ending effect is executed when the big winning device 23 is switched from the open state to the closed state, and when the big hit gaming state is ended (in this embodiment, at the end of the 15th round effect). It has become so.

  Then, after the symbol stop command is output, the main CPU 31a shown in FIGS. 3 and 4 generates an opening designation command for instructing the start of the opening effect, and outputs it as a control command. Next, the main CPU 31a sequentially outputs a round designation command instructing the start of the first to fifteenth round effects as a control command. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending effect as a control command.

(2-2) Electrical Configuration of Overall Control Board 32 As shown in FIGS. 3 and 4, the overall control board 32 includes an overall control CPU 32a that is a “game control means” and a “sub control means”. . The general control CPU 32a is electrically connected to an input buffer 37 for inputting a control signal and a read signal output from the main CPU 31a. Further, an input port 38 is electrically connected to the input buffer 37, and a control signal and a read signal are input to the overall control CPU 32a via the input port 38.

  Further, a general ROM 32b and a general RAM 32c are connected to the general control CPU 32a. The overall control CPU 32a updates the values of various random numbers used for determining the game effect at predetermined intervals. Then, the overall control CPU 32a rewrites the value before update by setting the updated value in the setting area of the overall RAM 32c. For example, the random number storage area of the overall RAM 32c stores a random number for lost left symbol, a random number for lost symbol, a random number for lost right symbol, and the like. Various flags that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the flag storage area of the overall RAM 32c. Various timers that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the timer storage area of the overall RAM 32c.

  Next, various processes related to the symbol variation game executed by the overall control CPU 32a shown in FIGS. 3 and 4 will be described. The general ROM 32b stores programs (effect mode setting program, effect symbol determination program) used for the various processes described above.

  When a variation pattern designation command is input from the main CPU 31a, the overall control CPU 32a stores the variation pattern designated by the variation pattern designation command in the overall RAM 32c. When the special symbol designation command is input, the overall control CPU 32a stores the special symbol B1 designated by the special symbol designation command in the overall RAM 32c. Further, the overall control CPU 32a confirms the symbol variation time corresponding to the variation pattern stored in the overall RAM 32c, and sets (temporarily stores) the symbol variation time in the overall RAM 32c as a changing timer. The overall control CPU 32a starts subtraction of the symbol variation time stored as the variation timer. At this time, the symbol variation time is subtracted every predetermined interrupt period (4 ms).

  The effect design determination program is a program for causing the overall control CPU 32a shown in FIGS. 3 and 4 to function as “effect design determination means”. That is, the overall control CPU 32a determines the effect symbol E1 to be stopped and displayed on the effect symbol display device 61 at the end of the effect symbol variation game based on the special symbol B1 stored in the overall RAM 32c. For example, if the special symbol B1 stored in the overall RAM 32c is “−” and the variation pattern stored in the overall RAM 32c is a variation pattern for a lost reach effect, the overall control CPU 32a determines the lose reach. . In this case, the overall control CPU 32a has the effect symbol E1 (the effect symbol left, middle, and right) to be finally stopped by the effect symbol display device 61. The left column and the right column are the same type of symbols, and the middle column is the left and right 2 columns. It is determined so as to be a different kind of symbol from the column. Specifically, the effect symbol left and the effect symbol right (both effect symbols are of the same type) are generated on the basis of the random number value for the lost symbol. Then, an effect symbol is generated based on the value of the random symbol for the lose symbol. If the value of the random symbol for losing pattern and the random number value for the losing left symbol (or the random number value for the losing right symbol) match, the overall control CPU 32a determines that the effect symbol in the effect symbol and the effect symbol left (or the effect symbol right). ) Are generated so that they do not match. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c. In the present embodiment, the numbers that can be taken by random numbers for the left symbol for lost, the random number for right for lost, and the random number for middle for lost are five integers from 0 to 4, and one numerical value corresponds to each type of symbol. It is attached.

  When the special symbol B1 stored in the overall RAM 32c is "-" and the variation pattern stored in the overall RAM 32c is a variation pattern for loss effect, the overall control CPU 32a shown in FIGS. Determine the loss. In this case, the overall control CPU 32a generates effect symbols left, middle, and right so that all columns do not become the same type of symbols. Specifically, the production symbol left is generated based on the value of the random symbol for the loss left symbol, the production symbol is generated based on the value of the random number for the middle symbol of the loss, and the production is produced based on the value of the random number for the loss right symbol. Generate the symbol right. If the value of the lost symbol random number and the value of the lost right symbol random match, the overall control CPU 32a generates the effect symbol right so that the effect symbol left does not match the effect symbol right. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c.

  Furthermore, when the special symbol B1 stored in the overall RAM 32c is any one of “0” to “9”, the variation pattern stored in the overall RAM 32c is a variation pattern for the big hit effect. In this case, the overall control CPU 32a generates effect symbols left, middle, and right so that all columns are of the same type. More specifically, the overall control CPU 32a generates the effect symbol left, the effect symbol in the effect symbol, and the effect symbol right (each effect symbol is the same type) based on the special symbol B1. The generated effect symbol E1 (effect symbol left, middle, right) is derived to the effect symbol display device 61 as a final symbol combination. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c.

  Note that the overall control CPU 32a shown in FIGS. 3 and 4 can determine the effect symbol E1 from all of the plurality of types of effect symbols E1 regardless of whether or not the probability variation state is given. More specifically, the overall control CPU 32a determines whether the special symbol B1 stored in the overall RAM 32c is a symbol indicating any number among symbols indicating numbers "0" to "9". Any one of the production symbols E1 indicating the numbers of “4” is determined. That is, the effect design E1 indicating the numbers “0” to “4” is a design in which it is impossible to determine whether or not it is in the probability variation state. In other words, the effect symbol E1 indicating the numbers “0” to “4” is a symbol (so-called “chance symbol”) indicating that there is a possibility of a probability variation state. That is, the overall control CPU 32a has a function as a “concealing means” for concealing whether or not the probability variation state is given and concealing the jackpot number X that is a probability variation big hit during the probability variation state. ing. Therefore, in this embodiment, the expectation level to which the probability variation state is given is equal regardless of which effect symbol E1 is determined among the effect symbols E1 indicating the numbers “0” to “4”.

  The effect mode setting program is a program for causing the overall control CPU 32a shown in FIGS. 3 and 4 to function as “effect mode setting means”. That is, when the result of the symbol variation game is a big hit, the overall control CPU 32a regardless of whether or not the probability variation state is given (that is, the special symbol B1 stored in the overall RAM 32c is a probability variation symbol). Regardless of whether or not), the same effect mode is set as the effect mode in the symbol variation game after the end of the big hit gaming state. In this embodiment, the probability variation concealment mode for concealing that the probability variation state is given is set as the effect mode. In the probability variation concealment mode, the same background (blue background in the present embodiment) is displayed on the effect symbol display device 61 regardless of whether or not the probability variation state is given. That is, the overall control CPU 32a has a function as a “concealing means” for concealing whether or not a probability variation state is given and concealing the jackpot number X that is a probability variation big hit during the probability variation. Yes.

  The central control CPU 32a shown in FIGS. 3 and 4 uses a variation pattern designation command for designating a variation pattern stored in the overall RAM 32c as a control command, the display control CPU 33a of the display control board 33, and the voice / lamp. The sound is output to the sound / lamp control CPU 34a of the control board 34. As a result, the specific content of the game effect executed by the display control board 33 and the sound / lamp control board 34 is comprehensively controlled by the overall control board 32. The overall control CPU 32a outputs an effect mode designation command for designating an effect mode stored in the overall RAM 32c to the display control CPU 33a and the sound / lamp control CPU 34a.

  Furthermore, the overall control CPU 32a outputs an effect symbol left designation command for designating the effect symbol left of the effect symbol E1 to the display control CPU 33a as a control command. Similarly, the overall control CPU 32a sends, to the display control CPU 33a, an effect symbol right designation command for designating the effect symbol right of the effect symbol E1 and an effect symbol middle designation command for designating the effect symbol within the effect symbol E1 as control commands. Output. Thereafter, when a symbol stop command is input from the main CPU 31a, the overall control CPU 32a outputs the input symbol stop command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

  When an opening designation command is input from the main CPU 31a, the overall control CPU 32a shown in FIGS. 3 and 4 outputs the input opening designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a. . Next, when a round designation command for the first to fifteenth round effects is inputted from the main CPU 31a, the overall control CPU 32a uses the inputted round designation command as a control command for the display control CPU 33a and the sound / lamp control CPU 34a. Output to. Thereafter, when an ending designation command is input from the main CPU 31a, the overall control CPU 32a outputs the input ending designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

  The overall control CPU 32a uses the above control commands as control signals (8-bit signals) and outputs the signals via the output port 39 and the output buffer 40 at a predetermined timing. Further, the overall control CPU 32a, in accordance with the output timing of the control signal, instructs the display control board 33 and the sound / lamp control board 34 to read a control command constituting the control signal (INT signal or , The strobe signal) is output via the output port 39 and the output buffer 40.

(2-3) Electrical Configuration of Display Control Board 33 As shown in FIG. 3, the display control board 33 includes a display control CPU 33a.

  Next, processing (big hit end processing) performed by the main CPU 31a of the main control board 31 will be described. The jackpot end process is a process that is performed when the jackpot gaming state is ended. Further, the program for performing the big hit ending process is executed in the main CPU 31a every predetermined interrupt cycle (every 4 ms).

  In step S10 shown in FIG. 6, the main CPU 31a sets (stores) the data of the special symbol probability change preliminary flag as flag data in the main RAM 31c. Then, when the flag data stored in the main RAM 31c is the special symbol probability changing reserve flag 01H, the main CPU 31a gives a probability variation state after the big hit gaming state is finished. On the other hand, when the flag data stored in the main RAM 31c is the special symbol probability changing reserve flag 00H, the main CPU 31a does not give the probability variation state even after the end of the big hit gaming state.

  In step S10, the main CPU 31a sets (stores) the data of the variable time shortening reserve flag in the main RAM 31c as flag data. Then, when the flag data stored in the main RAM 31c is the variation time shortening reserve flag 01H, the main CPU 31a gives the variation time shortening state after the end of the big hit gaming state. When the fluctuation time shortening reserve flag 00H is stored as flag data in the main RAM 31c, the special symbol probability variation reserve flag 01H is also stored as flag data in the main RAM 31c. The special symbol probability change preliminary flag 01H is a flag for instructing the provision of the variation time shortening state in addition to the provision of the probability variation state. Therefore, in this embodiment, even if the flag data stored in the main RAM 31c is the variation time shortening reserve flag 00H, the variation time shortening state is given after the big hit gaming state is finished. Then, the main CPU 31a ends the process here.

  Next, processing (big hit determination processing) performed by the main CPU 31a of the main control board 31 will be described. Note that a program for performing this process is executed in the main CPU 31a every predetermined interrupt period (every 4 ms).

  In the process of step S110 shown in FIG. 7, the main CPU 31a determines whether or not the number of starting reserved balls is larger than “0”. When the number of starting reserved balls is “0” (step S110: N), the main CPU 31a ends the process here without performing the processes of steps S120 to S140. On the other hand, when the number of starting reserved balls is larger than “0” (step S110: Y), the main CPU 31a proceeds to the process of step S120.

  In step S120, the main CPU 31a determines whether or not the result of the symbol variation game is a big hit. Specifically, the main CPU 31a determines whether or not the variation pattern determined by performing the big hit determination is a variation pattern for a big hit effect selected at the time of the big hit. When the result of the symbol variation game is not a big hit (step S120: N), the main CPU 31a executes the process of step S140 (losing symbol creation process), and ends the process here.

  On the other hand, when the result of the symbol variation game is a big hit (step S120: Y), the main CPU 31a proceeds to the process of step S130 (big hit symbol creation processing) and executes the subroutine shown in FIG. The subroutine of FIG. 8 includes the processes of steps S210 to S280. In step S210, the main CPU 31a acquires the special symbol type flag, the special symbol probability variation reserve flag, and the variation time reduction reserve flag stored in the flag storage area of the main RAM 31c, and proceeds to the processing of step S220. In step S220, the main CPU 31a determines whether or not the result of the symbol variation game is a probability variation jackpot based on the value of the acquired special symbol probability variation preliminary flag. When it is determined that the result of the symbol variation game is not the probability variation big hit, that is, when the special symbol probability variation preliminary flag is “00H” (step S220: N), the main CPU 31a does not perform the processing of steps S230 and S240. The process proceeds to step S250. On the other hand, when it is determined that the result of the symbol variation game is a probability variation jackpot, that is, when the special symbol probability variation reserve flag is “01H” (step S220: Y), the main CPU 31a proceeds to the processing of step S230.

  In step S230, the main CPU 31a determines whether or not the big hit count X stored in the main RAM 31c is larger than the upper limit (3) of the big hit count X stored in the main ROM 31b. . When it is determined that the number of big hits X is larger than the upper limit (step S230: Y), the main CPU 31a proceeds to the process of step S240. In step S240, the main CPU 31a adds the value of the special symbol type flag by “+ 05H”, and proceeds to the process of step S250. On the other hand, when it is determined that the big hit number X is equal to or less than the upper limit value (step S230: N), the main CPU 31a proceeds to the process of step S260.

  In step S250, since the value of the special symbol probability change preliminary flag is “00H”, the main CPU 31a clears the big hit count X stored in the main RAM 31c (sets it to 0), and performs the process of step S270. Migrate to In step S260, the main CPU 31a adds 1 to the big hit number X stored in the main RAM 31c, and proceeds to the process of step S270.

  In step S270, the main CPU 31a stores the acquired special symbol probability variation reserve flag and variation time reduction reserve flag in the flag storage area of the main RAM 31c, and proceeds to the processing of step S280. In step S280, the main CPU 31a sets a variation pattern. Specifically, the main CPU 31a sets (stores) a variation pattern for a big hit effect in the main RAM 31c. In step S280, the main CPU 31a determines a special symbol B1 indicating any one of “0” to “9” based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM 31c. Thereafter, the main CPU 31a ends this subroutine and ends the jackpot determination process shown in FIG.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 according to the present embodiment, it is possible to make the effect symbol E1 unrecognizable as to whether the effect symbol E1 is in the probability variation state, or to determine whether the effect effect state ( By setting (probable concealment concealment mode), the number of jackpots X in the probability variation state is concealed. Thereby, the player can enjoy the game characteristic which presumes the information “whether or not the big hit number X has reached the upper limit?” Which is information to be known. Further, since it is also kept secret whether or not the probability variation state is given by the setting of the effect symbol E1 and the effect mode, the player also guesses the information “whether or not the probability variation state is given”. You can enjoy the game. As a result, since the number of jackpots X has reached the upper limit and the provision of the probability variation state is terminated, or it is not known that the jackpot is not in the probability variation state, the player can play the game with a sense of tension. As a result, the feeling of expectation for the result of the next symbol variation game will continue.

  (2) For example, it is conceivable that the probability that the probability variation state is given after the end of the jackpot gaming state is set to 100%. However, it gradually becomes clear that the probability variation big hit always occurs when the result of the symbol fluctuation game becomes a big hit. Further, once the result of the symbol variation game is a big hit, it is understood that the probability variation big hit is continued until the number of big hits X reaches the upper limit value. As a result, the interest of the game is reduced. Therefore, in this embodiment, the probability that the probability variation state is given is set to less than 100% (specifically, 80%). In this case, even if the result of the symbol variation game is a big hit, the probability variation big hit is not always achieved. Therefore, even when the game is performed for a long time, it is possible to cause the player to guess the provision of the probability variation state, so that it is possible to prevent a decrease in interest.

  (3) In the present embodiment, when the number of big hits X has reached the upper limit value, the special symbol type probable preliminary flag determined based on the special symbol type flag is simply added to the value of the special symbol type flag by “+ 05H”. Is changed from “01H” to “00H”, and the provision of the probability variation state is terminated. In other words, since it is not necessary to perform processing such as outputting a command for terminating the provision of the probability variation state, the control is not complicated, and the provision of the probability variation state is terminated when the number of jackpots X reaches the upper limit value. It is easy to realize the processing to be performed.

  (4) In this embodiment, when the value of the special symbol type flag is incremented by “+ 05H”, the variation time shortening preliminary flag is changed as the special symbol probability variation preliminary flag is changed from “01H” to “00H”. It is always changed to “01H”. That is, even if the number of big hits X reaches the upper limit value and the provision of the probability variation is completed, the provision of the variation time reduction state can be expected, so that the player can be motivated to continue the game.

  (5) In the present embodiment, the special symbol B1 displayed on the special symbol display device 51 is a symbol (a symbol that is not a character or a number) that does not make sense in appearance (see FIG. 2). That is, the special symbol B1 is a symbol that cannot be determined as to whether or not it is in the probability variation state, like the effect symbol E1. Therefore, since it becomes more difficult to understand whether or not the probability variation state is given, it is possible to reliably prevent a decrease in interest when the probability variation state is not given.

  In addition, you may change the said embodiment as follows.

  In the above embodiment, only one upper limit value for the number of big hits X is set, but a plurality of upper limit values may be set.

  In the above embodiment, when the result of the symbol variation game is a big hit, only one kind of effect mode (probability change concealment mode) is set, but one of the plurality of kinds of effect modes is set. A production mode may be set. For example, one effect mode may be set from among a plurality of types of effect modes having different degrees of expectation as to whether or not the probability variation state is given during the variation time reduction state after the big hit gaming state. Good. Specifically, the first effect mode in which the blue background is displayed on the effect symbol display device 61, the second effect mode in which the yellow background is displayed on the effect symbol display device 61, and the red background is the effect symbol. One effect mode may be set from the third effect modes displayed on the display device 61. Then, as the effect mode changes in the order of the first effect mode → the second effect mode → the third effect mode, the degree of expectation as to whether or not the probability variation state is given may be increased. In this case, when the special symbol B1 is a probability variation symbol, the third rendering mode is set to the highest probability, and when the special symbol B1 is a non-probability variation symbol, the first rendering mode is set. The highest probability may be. Further, when the special symbol B1 is a probability variation symbol, the rendering mode is easily shifted to the third rendering mode, and when the special symbol B1 is a non-probability variation symbol, the rendering mode is easily transitioned to the first rendering mode. It may be.

  In the above embodiment, the expectation level to which the probability variation state is given is equal regardless of which effect symbol E1 is determined among the effect symbols E1 indicating the numbers “0” to “4”. However, the degree of expectation (probability) to which the probability variation state is given may be varied in accordance with the determined type of effect design E1. For example, you may make it raise the probability that a probability fluctuation state will be provided, so that the number (distance) which the production design E1 shows becomes large.

  In the above embodiment, it is concealed whether or not the probability variation state is given. However, for some probability variation jackpots, a probability variation that notifies that the probability variation jackpots are made using the speakers 17a to 17c or the like. A notification effect may be executed. For example, the probability change notification effect may be executed when a probability variation big hit is achieved with the effect symbol E1 indicating the number “7”. In this way, the probability change notification effect serves as a material for estimating when the next probability fluctuation jackpot will be. In addition, since the fact that the probability variation state is given is sometimes notified, it becomes an accent of the game and the interest is improved. When executing the probability change notification effect, the variation time shortening state may be continued only until the next big hit gaming state is started. That is, since the player can know the provision of the probability variation state, even if the provision of the variation time reduction state is completed, the interest of the game is not easily lowered.

  In the above-described embodiment, the main CPU 31a performs the “hit determination unit”, “hit game state giving unit”, “probability variation state giving determination unit”, “probability variation state giving unit”, “hit number calculation unit”, “hit It has functions as “number of times determination means”, “big hit number clearing means”, “probability variation state giving means” and “variation time shortening state giving means”. However, the overall control CPU 32a may be provided with the functions of “hit number calculation means”, “hit number determination means” and “hit number clear means”. That is, the overall control CPU 32a may have a function related to the processing of the big hit number X. In this way, it is possible to reduce the burden on the main CPU 31a despite having a function (so-called limiter function) for limiting the number of big hits (so-called consecutive times) in the probability variation state.

  When the overall control CPU 32a has a function related to the processing of the big hit count X, the main CPU 31a and the overall control CPU 32a perform, for example, the following processing. That is, the main CPU 31a outputs a big hit signal to the overall control CPU 32a when the probability fluctuation big hit occurs during the probability fluctuation state. On the other hand, the overall control CPU 32a adds 1 to the number of jackpots X when a jackpot signal is input from the main CPU 31a. Next, the overall control CPU 32a compares the jackpot number X stored in the overall RAM 32c with the upper limit value “3” of the jackpot number X stored in the overall ROM 32b, thereby setting the jackpot number X to the upper limit value. It is determined whether it has been reached. If it is determined that the big hit number X has reached the upper limit value, the overall control CPU 32a clears the big hit number X (sets it to zero).

  -Although the structure in the said embodiment was applied to the game machine provided with only one start prize apparatus and a special symbol display apparatus, you may apply to the game machine provided with two start prize apparatuses and two special symbol display apparatuses. .
