Description

The present invention relates to Yu technique machine.

  Conventionally, in a pachinko machine that is a kind of gaming machine, a variable symbol display game is performed in which a variable display device displays a plurality of different symbols. When the display result of the symbol variation game is a display result indicating a big hit, a big hit game is given. In the jackpot game, the player is given an opportunity to acquire a large number of game balls. The jackpot includes a probability variation jackpot that gives a probability variation (hereinafter referred to as “probability change”) state after the jackpot game ends, and a non-probability change jackpot that does not give a probability change state after the jackpot game ends. Some game machines were equipped. The probabilistic state is a state in which the probability of winning the jackpot is changed from a normal probability with a low probability to a high probability, and the probable state is a game that is more advantageous than the normal probability because the winning probability of the jackpot for the player is high. State. The probability variation big hit and the non-probability big hit are generally dependent on the display result of the symbol variation game.

In such a pachinko machine, whether or not it will be a promising big hit depends on the display result, so the game performance is clear, but the big hit game given after the display result is derived is a lot of game balls There is a concern that the game will be in a state just for acquisition, that is, a game state that is simply digested, and the interest of the game will be reduced. In order to dispel this concern, the probability variation big hit is not made dependent on the display result, and the probability variation state is not notified. A gaming machine has been proposed that performs a probability variation latent effect that suggests the possibility of a probability variation state after the big hit gaming state (see Patent Document 1). According to this, even in the game after the end of the big hit gaming state, it is possible to be interested in whether or not the probability variation state has been given, and it is possible to improve the interest of the game. In Patent Document 1, the probability variation latency effect is performed even if the probability variation state is not given, so that it is determined whether or not the probability variation state is imparted even if the probability variation latency effect is performed to the player. I try not to let it.

The variation pattern determining means determines a variation pattern for an outlier reach effect when the reach determination means makes an affirmative determination, and the display control means is based on the variation pattern for the outlier reach effect. When the display effect relating to the variable game is performed, during the reach effect, a background image for reach effect different from the background image stored in the background image storage means is displayed, and the background switching means When the variation pattern determining means determines a variation pattern for a predetermined outlier reach effect, the variation pattern for the predetermined outlier reach effect is determined. When off display results reach demonstration is completed in a display effect according to the symbol variation game based on the emission is stopped and displayed once the previous SL background selection means to be displayed by changing the background image selected as the background of the display screen Is the gist.

According to the present invention, when the effect of changing the image is executed regardless of the gaming state, and when the effect of changing the image is executed during the non-probability change state, the selection probability of each image to be changed is changed to the probability change state. By making it different from the inside, it is possible to make the player always expect that the probability variation state is given. Further, according to the present invention, when the background image is changed, it can be correctly changed.

Hereinafter, an embodiment in which the present invention is embodied in a pachinko gaming machine (hereinafter referred to as a “pachinko machine”), which is a kind of gaming machine, will be described with reference to FIGS.
In FIG. 1, the front side of the pachinko machine 10 is schematically shown, and a vertical rectangular middle frame 12 for setting various game components is opened and closed on the front side of the opening of the outer frame 11 that forms the outline of the machine body. And is detachably assembled. On the front side of the middle frame 12, a front frame 14 having a glass frame on which a protective glass for protecting the game board 13 disposed inside the machine is mounted and an upper ball tray 15 are opened and closed in a laterally open state. It is assembled as possible. On the front side of the front frame 14 and the game area 13 a of the game board 13, a decoration lamp 16 that performs a light emission effect by light emission (lighting (flashing)) of a light emitter (LED, lamp, etc.) is provided. A speaker 17 that outputs various sounds and performs a game effect based on the sound output is arranged below the outer frame 11. A lower ball tray 18 and a launching device 19 are attached to the lower part of the middle frame 12. Then, when the player operates the launching device 19 to drive the launching device 19, the game ball in the upper ball tray 15 is launched into the game area 13 a of the game board 13.

  In the approximate center of the game area 13a of the game board 13, there is a center accessory 20 provided with a special display H1 as a 7-segment type special display means and a variable display H2 as a liquid crystal display type display means. It is installed. As shown in FIG. 2, the special-purpose display H <b> 1 is provided at the upper part of the center accessory 20, and the variable indicator H <b> 2 is provided at the center of the center accessory 20. The special symbol display H1 executes a symbol variation game in which a plurality of types of symbols are varied and displayed. In the variable display H2, a display effect related to the symbol variation game performed in the special figure display H1 is performed. Specifically, the variable display H2 performs a display effect based on a varying image (or image display), and displays a symbol combination by varying a plurality of types of symbols in a plurality of columns in relation to the display effect. A symbol variation game (hereinafter sometimes referred to as a symbol combination game) is played.

  In the symbol variation game, the special symbol display H1 displays a special symbol by varying a plurality of types of special symbols F0 (hereinafter referred to as “special symbols”) in one column. This special figure is a notification pattern indicating the result of the internal lottery such as whether or not a big hit. On the other hand, in the display effect related to the symbol variation game, the variable display H2 changes a plurality of types of ornamental symbols F1 (hereinafter referred to as “decorative diagrams”) in a plurality of columns (in this embodiment, three columns) for each column. Display a decorative drawing. This decorative drawing is a design for production used for diversifying display production.

  On the special symbol display H1, the symbol variation display is started simultaneously with the start of the symbol variation game, and the special symbol is confirmed and stopped simultaneously with the end of the game. In addition, the variable display H2 starts the decorative display of the decorative drawing simultaneously with the start of the symbol changing game, and in principle, the decorative drawing is temporarily stopped and displayed in a swinging and changing state before the game ends. The decoration of the column is displayed in a fixed stop state. “Fluctuation display” is a state in which the type of the symbol displayed in the display area defined in the display device for displaying the symbol is changing. “Temporary stop display” means that the symbol is shaken in the display area. In this embodiment, the symbol is not displayed in a variable state again, and the symbol type is not changed. The “definite stop display” is a state in which the symbols are fixed and stopped in the display area. In principle, on the special symbol display H1 and the variable display H2, the display effects relating to the symbol variation game and the symbol variation game are started at the same time, and are simultaneously ended (that is, the special symbol and the decoration drawing are displayed in a fixed stop state at the same time. ).

  In the present embodiment, the special figure display H1 displays four types of numbers [0], [1], [2], and [3] and a symbol [-] as special figures. Yes. When the symbol finally displayed (definite stop display) on the special symbol display H1 is a number from [0] to [3], the big hit and the small hit can be recognized from the symbol. The symbol that can recognize the big hit and the small hit becomes the big hit symbol and the small hit symbol in the special drawing. On the other hand, when the symbol confirmed and displayed on the special symbol display H1 is [-], a deviation from the symbol can be recognized. The symbol that can recognize the deviation is the symbol of the deviation in the special figure.

  In the present embodiment, the variable display H2 includes 8 [1], [2], [3], [4], [5], [6], [7], and [8] for each column. Different numbers are displayed as decorative drawings. In the present embodiment, the variable display H2 is configured with a large display area as compared with the special figure display H1, and the decorative drawing is displayed much larger than the special figure. . For this reason, the player can recognize a big hit or miss from the symbol combination stopped and displayed on the variable display H2. When the symbols of all the columns stopped and displayed on the variable display H2 are of the same type, the big hit can be recognized from the symbol combination ([222] [777] or the like). The symbol combination that can recognize this jackpot is a jackpot symbol combination (big hit display result) by a decorative drawing. When the jackpot symbol combination is confirmed and stopped, the player is awarded a jackpot game after the symbol variation game is over. On the other hand, when the symbols of all the columns that are confirmed and stopped displayed on the variable display H2 are of different types, or when the symbols of one column are of a different type from the symbols that form the reach state, the symbol combination ([123] [122] [767] etc.) can be recognized. The symbol combination which can recognize this deviation becomes a symbol combination (outlier display result) of the deviation by the decorative drawing.

  Further, in the present embodiment, each row in the variable display H2 is configured such that the decorative drawing is variably displayed along a predetermined variation direction (vertical scroll direction) when the symbol variation game is started. Then, when the symbol variation game starts (when the decorations in each column start to vary), the left column (left symbol) → the right column (right symbol) → the middle column (middle) as viewed from the player side on the variable display H2. The decorative drawings are stopped and displayed in the order of symbols. When the left symbol and the right symbol that are stopped and displayed are of the same type, the reach state can be recognized from the symbol combination ([↓] indicates that the symbol is changing, such as [1 ↓ 1]). In the reach state, among the plurality of columns, the decorative drawings of the specific columns (the left column and the right column in the present embodiment) are the same type and are stopped and displayed, and the columns other than the specific columns (the middle column in the present embodiment) Is a state in which the decorative drawing is displayed in a variable manner. Further, in the pachinko machine 10 of the present embodiment, after the start of the symbol variation game, the left column that first stops the decorative drawing becomes the first stop display column, and the right column that stops the decorative drawing next is the first column. The second stop display column is the third stop display column.

  The variable display H2 displays a symbol combination corresponding to the display result of the special figure display H1. More specifically, the symbol combination of the special symbol display H1 and the symbol combination of the variable display H2 correspond to each other. When the symbol variation game and the display effect relating to the symbol variation game are finished, the special symbol is displayed. The symbol combination by the symbol and the symbol combination by the decoration diagram are displayed in a fixed stop state correspondingly. For example, when the big hit symbol of [0] or [1] is confirmed and stopped on the special figure display H1, the combination of big hit symbols such as [111] and [222] is confirmed on the variable display H2. The stop is displayed. In addition, when the symbol of “-” is stopped and displayed in the special symbol display area H1, the symbol combination of “121” and “345” is fixedly stopped and displayed on the variable display H2. It has become. In addition, the symbol combination of the decorative drawing with respect to the special drawing is not necessarily one-to-one, and the symbol combination with one decorative drawing is selected from among the symbol combinations with a plurality of decorative drawings for one special drawing. Yes.

  As described above, in the variable display H2 of the present embodiment, the display effect related to the symbol variation game (the symbol variation game in which one column of symbols is variably displayed) performed on the special symbol display H1 is changed (three columns of symbols are varied). A symbol variation game that displays a combination of symbols is displayed.

  A start winning opening 22 having an opening / closing blade 21 that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown) is disposed below the center accessory 20. Behind the start winning opening 22 is provided a start opening sensor SE1 (shown in FIG. 3) that detects a winning game ball. The start winning opening 22 can give a start condition for the symbol variation game in response to detection of a game ball winning. Also, below the start winning opening 22, a large winning opening 23 as a winning means including a large winning opening door 24 which opens and closes by the operation of an actuator (solenoid, motor, etc.) not shown is arranged. When the big hit game is awarded, the big prize opening 23 is opened by the opening operation of the big prize door 24 and the game ball can be won, so that the player has a chance to obtain a large number of prize balls. There is a case. Note that the special prize opening door 24 and the special prize opening 23 of the present embodiment constitute a special prize winning device (large winning mouth device).

  The pachinko machine 10 according to the present embodiment stores the number of winning game balls when the game ball is won at the start winning opening 22, and stores the number of reserved game balls inside the machine (RAM 27c of the main control board 27) as a reserved storage number. It has come to be. The number of reserved memories accumulated when the symbol variation game is being performed indicates the number of symbol variation games being held (waiting for symbol variation game). The number of reserved memories is incremented by 1 when a game ball wins the start winning opening 22 and is decremented by 1 when the symbol variation game is started. Therefore, when a game ball wins the start winning opening 22 during the symbol variation game, the reserved memory number is further added and accumulated up to a predetermined upper limit number (four in this embodiment). Then, as shown in FIG. 2, between the special symbol display H1 and the variable display H2 of the center accessory 20 for informing the player of the number of symbol variation games that are pending based on the number of reserved memory. A reserved storage number display portion R is provided.

  The reserved memory number display portion R is configured by a light emitting means including a plurality of (four in this embodiment) LEDs including a hold lamp R1, a hold lamp R2, a hold lamp R3, and a hold lamp R4. A player is notified of the number of symbol variation games on hold by the number of lighting of the respective holding lamps R1 to R4. For example, when only the holding lamp R1 is lit, it indicates that one symbol variation game is being held, and when all the retention lamps R1 to R4 are lit, four symbol variation games are displayed. Indicates that it is pending.

  In addition, the pachinko machine 10 of the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function. The probability variation function changes the probability of winning a lottery (winning probability) from the normal probability (2/631 in the present embodiment), which is a low probability (normal state), to a high probability (10/631 in the present embodiment) after the jackpot game ends. This is a function for assigning a probability variation state (probability variation state).

  Further, the probability variation state is given until a predetermined number of times (10000 times in this embodiment) the symbol variation game is played, or until a big hit is generated before the number of games is reached. That is, the probability variation state is given until the end of the symbol variation game corresponding to a predetermined number of times, or until the end of the symbol variation game in which a big hit occurs before the number of times is reached. In this embodiment, since the probability variation state is set to 10000 as a predetermined number of times, it is substantially equivalent to being given until the next big hit occurs.

  A jackpot that gives a probability variation state after the big hit game ends becomes a probability variation big hit, and a jackpot that is not given a probability variation state after the big hit game ends becomes a non-probability big hit. If the probability variation state is given, the probability of winning the jackpot will fluctuate with a high probability and the jackpot is likely to occur. Therefore, the probability variation state is advantageous for the player, and the player expects the player to become a probability variation jackpot. It is carried out.

  The jackpot game of the present embodiment is started after the game in which the jackpot symbol is confirmed and stopped on the special symbol display H1 in the symbol variation game. 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, the round game in which the special winning opening 23 is opened is performed a plurality of times with a predetermined number of rounds as an upper limit (15 rounds or 2 rounds in the present embodiment). One round game is from when the big prize opening 23 is opened until it is closed, and during one round game, the big prize opening 23 has a predetermined number of game balls (10 balls in this embodiment). Until a prize is received or until a predetermined time (in this embodiment, 25 seconds when the number of specified rounds is 15 or 0.3 seconds when the number of specified rounds is 2) elapses. In round games, round effects are performed. Then, an ending effect indicating the end of the jackpot game is performed, and the jackpot game is ended. When the opening effect is executed, a background image for the opening effect is displayed on the variable display H2. When the round effect is executed, a background image for the round effect is displayed on the variable display H2. When the ending effect is executed, the variable display H2 displays the ending effect. A background image is displayed.

  Further, in the pachinko machine 10 of the present embodiment, as a big hit, a big hit 15R that sets the prescribed round number of round games in the big hit game as 15 times and a big hit 2R that sets the prescribed round number as 2 times are provided. When a jackpot 15R is awarded to a player, a jackpot game with a prescribed round number of 15 is given, and when a jackpot 2R is awarded to a player, a jackpot game with a prescribed round number of 2 Is granted. In this embodiment, a small hit determined separately from the big hit (big hit 15R and big hit 2R) is provided by internal lottery. Then, when the small winning is determined by the internal lottery and the small winning is given to the player, the prescribed number of rounds of the round game in which the large winning opening door 24 is opened and the large winning opening 23 is opened is twice. A small hit game determined as follows is given. Note that the time for the opening effect, the time for the round effect, and the time for the ending effect in the jackpot 2R jackpot game are the same as the time for the opening effect, the time for the round effect, and the time for the ending effect, respectively. In addition, the contents of the opening effect, the effect of the round effect, and the effect of the ending effect in the jackpot 2R jackpot game are the contents of the effect of the opening effect, the effect of the round effect, and the effect of the ending effect, respectively. Are the same. For this reason, it is difficult for the player to distinguish the small hit game and the big hit 2R big hit game from the viewpoint.

The big hit 15R includes a probability change big hit in which a probability change state is given after the big hit game ends and a non-probability big hit in which a probability change state is not given after the big hit game ends.
On the other hand, the big hit 2R has only a probable big hit that is given a probable change state after the big hit game ends. In other words, after the big hit 2R big hit game is finished, the probability variation state is always given.

  On the other hand, after the end of the small hit game by the small hit, the game state continues the game state at the time of winning the small hit. That is, after the small hit game is over, the game state is not changed. For this reason, after the end of the small hit game, if the gaming state at the time of winning the small hit is a normal state in which the winning probability of the big hit is a low probability, it does not shift to a probability variation state, while the winning probability of the big hit is a high probability When the probability variation state is, the probability variation state is continued. In the present embodiment, it is impossible to completely recognize whether or not a certain variation state is given from the jackpot symbol by the decorative drawing (in some cases, it can be recognized). In addition, the effect contents of the jackpot game and the effect contents of the symbol variation game and the symbol combination game that are the jackpot are the same regardless of the game state (probability change state or normal state), and the distribution (appearance rate) of the effect contents is also the same Since they are the same, it is impossible to completely recognize whether or not a certain change state is given from the contents of the production (in some cases, it can be recognized). That is, the pachinko machine 10 according to the present embodiment is configured to conceal whether or not a certain variation state is to be given. As described above, in this embodiment, the big hit game and the small hit game are special games. In the present embodiment, the first hit is 15R, the second hit is 2R, and the third hit is a small hit. The big hit game with the big hit 15R becomes the first special game, the big hit game with the big hit 2R becomes the second special game, and the small hit game becomes the third special game.

Next, the control configuration of the pachinko machine 10 will be described with reference to FIG.
A main control board 27 for controlling the entire pachinko machine 10 is mounted on the back side of the pachinko machine 10. The main control board 27 executes various processes for controlling the entire pachinko machine 10, performs arithmetic processing on various control signals (control commands) for controlling the game according to the processing results, and outputs the control signals ( Control command). In addition, an overall control board 28, a display control board 29, a lamp control board 30, and a sound control board 31 are mounted on the back side of the machine. The overall control board 28 comprehensively controls the display control board 29, the lamp control board 30 and the sound control board 31 based on the control signal (control command) output from the main control board 27. The display control board 29 controls the display mode (display images of symbols, backgrounds, characters, etc.) of the variable display H2 based on control signals (control commands) output from the main control board 27 and the overall control board 28. The lamp control board 30 controls the light emission mode (lighting (flashing) / lighting off timing, etc.) of the decorative lamp 16 based on control signals (control commands) output from the main control board 27 and the overall control board 28. The voice control board 31 controls the voice output mode (sound output timing, etc.) of the speaker 17 based on control signals (control commands) output from the main control board 27 and the overall control board 28. In the present embodiment, the main control board 27 serves as main control means. Further, the overall control board 28 becomes the overall control means. The display control board 29 serves as a display control means.

Hereinafter, specific configurations of the main control board 27, the overall control board 28, and the display control board 29 will be described.
The main control board 27 is provided with a main CPU 27a. A ROM 27b and a RAM 27c are connected to the main CPU 27a. The main CPU 27a is connected to a start port sensor SE1 that detects a game ball won in the start winning port 22. Further, the special CPU H1 is connected to the main CPU 27a. Further, the main CPU 27a is connected with a reserved memory number display section R. Further, the main CPU 27a updates the values of various random numbers such as a hit determination random number and a special figure distribution random number every predetermined cycle, and stores (sets) the updated value in the setting area of the RAM 27c before the update. The value of is rewritten.

  A main control program for controlling the entire pachinko machine 10 is stored in the ROM 27b. The ROM 27b stores a plurality of types of variation patterns. The variation pattern is a game effect (display effect, light emission) from when the symbol (special symbol and decoration) starts to fluctuate (the symbol variation game starts) until the symbol is stopped (the symbol variation game ends). This shows a pattern serving as a base for production and voice production. That is, the variation pattern is the effect content and variation time of the symbol variation game from when the special diagram on the special diagram display H1 starts to fluctuate until the special diagram is confirmed and stopped, and the decoration on the variable display H2. It is possible to specify the production contents and the variation time of the display production (design combination game) related to the design variation game from when the variation starts until the decorative drawing is displayed in a fixed stop state.

  More specifically, as shown in FIG. 4, the variation pattern includes, for each variation pattern, the variation time of the special diagram from the start to the end of the symbol variation game on the special symbol display H1 and the display on the variable display H2. The variation time of the decoration drawing from the start to the end of the production (design combination game) is determined. The variation pattern can be broadly divided into variation patterns P4, P5, P6, P8, and P9 that can be determined when the symbol variation game according to the special symbol is a big hit, and can be determined when the small hit is made. The variation patterns P5 and P9 can be classified into the variation patterns P1, P2, P3, P5, and P7 that can be determined when they are out of sync. Further, the variation patterns P4, P5, P6, P8, and P9 that can be determined when the symbol variation game by special symbol is a big hit are further determined when the symbol variation game by special symbol is a big hit 15R. Can be classified into fluctuation patterns P4, P6, P8 that can be changed and fluctuation patterns P5, P9 that can be determined when the big hit is 2R. Furthermore, the variation patterns P1, P2, P3, P5, and P7 that can be determined when the symbol variation game according to the special figure is lost can be determined when the symbol variation game due to the special symbol is out of reach. The variation patterns P3, P5, and P7 can be classified into the variation patterns P1 and P2 that can be determined when the reach does not reach reach.

  In the present embodiment, the variation pattern determined when the symbol variation game is a small hit is different only in the result on the special symbol display H1 (result of the symbol variation game). Since the variation time and the like are the same, the variation patterns P5 and P9 determined when the jackpot is 2R are shared. In addition, the variation pattern determined when the symbol variation game is out of reach only differs in the result (result of the symbol variation game) on the special symbol display H1, and the effect contents and variation time of the specified game effect are different. Therefore, the variation pattern P5 determined when the jackpot is 2R is shared.

  In the following description, the variation patterns P4, P5, P6, P8, and P9 that can be determined when the symbol variation game with a special symbol is a big hit may be indicated as the big hit effect variation pattern. In addition, the variation patterns P4, P6, and P8 that can be determined when the symbol variation game based on the special figure becomes the big hit 15R may be shown as the variation pattern for the big hit 15R effect. Further, there are cases where the variation patterns P5 and P9 that can be determined when the symbol variation game based on the special figure is 2R jackpot are shown as variation patterns for the jackpot 2R effect. In addition, there are cases where the variation patterns P5 and P9 that can be determined when the symbol variation game with a special figure is a small hit are shown as variation patterns for the small hit effect. In addition, the variation patterns P3, P5, and P7 that can be determined when the symbol variation game according to the special figure is out of reach may be shown as a variation pattern for outlier reach production. In addition, the variation patterns P1 and P2 that can be determined when the symbol variation game by the special figure is out of place (no reach effect) may be shown as the variation pattern for the outage effect.

  In the present embodiment, in the symbol variation game based on the variation pattern for the jackpot effect and the variation pattern for the outlier reach effect, one of the three types of reach effects N, SA, SB is performed. ing. For example, the reach effect N is such that after the reach symbol combination by the decoration drawing is displayed, the reach effect is performed with the effect of deriving the decoration drawing by changing the remaining one column (in this embodiment, the middle row). (Also called normal reach production). In addition, the reach effects SA and SB are displayed while the remaining one row of decorative drawings is changing or once displayed, for example, a specific character appears and moves to “XX reach” called by the name of the appearing character (development). Thus, the reach production is performed with the production content for deriving the decorative design (also called super reach production). In the present embodiment, the reach effect N (normal reach effect) is a normal reach effect, and the reach effects SA, SB (super reach effect) are reach effects that develop in stages. During the reach production, a background image for reach production is displayed.

  In the present embodiment, the ratio of jackpot game (hit reliability or jackpot expectation) is varied according to the type of reach effect. More specifically, the reach effects SA and SB are set higher than the reach effect N so that the ratio of the big hit game is given. This indicates that the reach production SA and SB have higher expectation level (possibility) that the big hit game is given than the reach production N. The ratio at which the jackpot game is given is determined in accordance with the distribution mode when the variation pattern in which each reach effect is performed is distributed to the reach effect instead of the jackpot effect. In other words, in order to increase the percentage that the jackpot of the reach effect is given, the jackpot is larger than the ratio that the reach effect appears in the symbol combination game (the overall ratio that appears in the case of reach instead of the jackpot). In this case, the variation pattern may be distributed so as to increase the rate at which the reach effect appears and reduce the rate at which the reach effect appears at the time of outlier reach (or perform one of them). In this way, by changing the ratio of winning jackpot games, the reach symbol combination is displayed, and when a reach effect is performed, the player's expectation for the jackpot according to the type of reach effect The feeling can be changed.

  Then, when the symbol variation game is played based on the variation pattern P4, P6, P8 for the big hit 15R effect, the special symbol display H1 and the variable display H2 can recognize the big hit and the big hit symbol, respectively. A combination (for example, [111]) is finally displayed. Specifically, as shown in FIG. 4, when the symbol variation game is performed based on the variation pattern P4 for the big hit 15R effect, the reach effect N is performed on the variable display H2, and then the big hit symbol by the decorative drawing is performed. At the same time that the combination is displayed, the special symbol display H1 displays a jackpot symbol. When the symbol variation game is performed based on the variation pattern P6 for the jackpot 15R effect, after the reach effect SA is performed by the variable display H2, the symbol combination of the jackpot by the decorative drawing is displayed and at the same time the special symbol display A jackpot symbol is displayed in H1. When the symbol variation game is performed based on the variation pattern P8 for the jackpot 15R effect, after the reach effect SB is performed by the variable display H2, the symbol combination of the jackpot by the decorative drawing is displayed, and at the same time, the special symbol display A jackpot symbol is displayed in H1.

  The variation time of the display effect (the symbol combination game) related to the symbol variation game on the special symbol display H1 and the symbol variation game on the variable indicator H2 specified by the variation pattern P4 is 25 seconds. Also. The variation time of the display effect (the symbol combination game) related to the symbol variation game on the special symbol display H1 and the symbol variation game on the variable indicator H2 specified by the variation pattern P6 is 35 seconds. Also, the variation time of the display effect (the symbol combination game) related to the symbol variation game on the special symbol display H1 and the symbol variation game on the variable indicator H2 specified by the variation pattern P8 is both 60 seconds.

  Then, when the symbol variation game is performed based on the variation patterns P5 and P9 for the big hit 2R effect, the big hit symbols that can be recognized by the special symbol display H1 are finally displayed. When a symbol variation game is performed based on the variation pattern P5, P9 for the big hit 2R effect, the big combination cannot be recognized by the variable display H2, and the symbol combination different from the big hit symbol combination in the big hit 15R (for example, [[ 345] [323] etc. are finally displayed. Specifically, as shown in FIG. 4, when the symbol variation game is performed based on the variation pattern P5 for the big hit 2R effect, the reach indication SA is performed on the variable display H2, and then the big hit symbol by the decorative drawing is displayed. A symbol combination different from the combination is displayed, and at the same time, a big hit symbol is displayed on the special symbol display H1. When the symbol variation game is played based on the variation pattern P9 for the big hit 2R effect, the big hit symbol is displayed on the special symbol display H1 after 2 seconds from the start of the symbol variation game, and is variable after 12 seconds from the start of the symbol variation game. In the display H2, a symbol combination different from the jackpot symbol combination by the decorative drawing is displayed.

  Note that the variation times of the display effects (design combination game) related to the symbol variation game on the special symbol display H1 and the symbol variation game on the variable indicator H2 specified by the variation pattern P5 are both 30 seconds. The variation time of the symbol variation game on the special symbol display H1 specified by the variation pattern P9 is 2 seconds, while the display effect (the symbol is related to the symbol variation game on the variable indicator H2 identified by the variation pattern P9. The variation time of the combination game) is 12 seconds.

  Further, when the symbol variation game is performed based on the variation patterns P5 and P9 for the small hit effect, the small hit symbol that can be recognized by the special symbol display H1 is finally displayed, and the big hit is displayed by the variable display H2. The symbol combination (for example, [678]) different from the jackpot symbol combination at the jackpot 15R is finally displayed. Specifically, as shown in FIG. 4, when the symbol variation game is performed based on the variation pattern P5 for the small hit effect, after the reach effect SA is performed by the variable display H2, the symbol of the big hit by the decorative drawing is performed. A symbol combination different from the combination is displayed, and at the same time, a small hit symbol is displayed on the special symbol display H1. When the symbol variation game is executed based on the variation pattern P9 for the small hit effect, the symbol for the small hit is displayed on the special symbol display H1 after 2 seconds from the start of the symbol variation game, and at the same time, 12 seconds from the start of the symbol variation game. Later, on the variable display H2, a symbol combination different from the jackpot symbol combination by the decorative drawing is displayed.

  Note that the variation times of the display effects (design combination game) related to the symbol variation game on the special symbol display H1 and the symbol variation game on the variable indicator H2 specified by the variation pattern P5 are both 30 seconds. The variation time of the symbol variation game on the special symbol display H1 specified by the variation pattern P9 is 2 seconds, while the display effect (the symbol is related to the symbol variation game on the variable indicator H2 identified by the variation pattern P9. The variation time of the combination game) is 12 seconds.

  As described above, when the symbol variation game is performed based on the variation pattern P5 for the small hit effect and when the symbol variation game is performed based on the variation pattern P5 for the big hit 2R effect, the variable display H2 The production contents of the display effect, the variation time of the decoration drawing, the display result of the decoration drawing, the variation time of the special drawing, and the like are the same, and only the display result of the special drawing is different. For this reason, if the main CPU 27a stores and manages the display result (the result of the symbol variation game) based on the special graphic, the variation pattern P5 can be shared even when the symbol variation game is a small hit. The same applies to the variation pattern P9. For this reason, when the symbol variation game is played based on the variation pattern P5, the player cannot distinguish whether the symbol variation game is the big hit 2R or the small hit from the contents of the effect of the variable display H2. It is like that.

  When the symbol variation game is performed based on the variation pattern P3, P5, and P7 for the outlier reach effect, the special symbol display device H1 and the variable display device H2 each have a symbol combination and a symbol combination of dislocation. It is displayed. Specifically, as shown in FIG. 4, when the symbol variation game is performed based on the variation pattern P3 for the outlier reach effect, after the reach effect N is performed with the variable display H2, the deviation due to the decoration diagram is displayed. At the same time that the symbol combination is displayed, the special symbol display H1 displays a symbol that is out of place. When the symbol variation game is performed based on the variation pattern P5 for the outlier reach effect, after the reach effect SA is performed with the variable display H2, the symbol combination of the outliers by the decorative drawing is displayed and at the same time, the special symbol display is performed. In the device H1, a symbol of dislocation is displayed. When the symbol variation game is performed based on the variation pattern P7 for the outlier reach effect, after the reach effect SB is performed with the variable display H2, the symbol combination of the outliers by the decorative drawing is displayed, and at the same time, the special symbol display In the device H1, a symbol of dislocation is displayed.

  As described above, when the symbol variation game is performed based on the variation pattern P5 for the outlier reach effect and when the symbol variation game is performed based on the variation pattern P5 for the jackpot 2R effect, the variable display H2 The production contents of the display effect, the variation time of the decoration drawing, the display result of the decoration drawing, the variation time of the special drawing, and the like are the same, and only the display result of the special drawing is different. For this reason, if the main CPU 27a stores and manages the display result (the result of the symbol variation game) based on the special graphic, the variation pattern P5 can be shared even when the symbol variation game is out of reach. Then, when the symbol variation game is played based on the variation pattern P5, the player determines whether the symbol variation game is a big hit 2R, a small hit, or a missed reach from the contents of the variable display H2. It is indistinguishable.

  Then, when the symbol variation game is performed based on the variation patterns P1 and P2 for the offending effect, the special symbol display H1 and the variable display H2 each have a final symbol combination and a deviant symbol combination after the normal variation. It is a pattern displayed in. Specifically, as shown in FIG. 4, when the symbol variation game is performed based on the variation pattern P1 for the offending effect, the normal variation is performed after the symbol variation game is started, and after 12 seconds from the start, the variable display is performed. The symbol H2 is displayed on the device H2, and the symbol combination is displayed on the special display H1. Further, when the symbol variation game is performed based on the variation pattern P2 for the offending effect, the normal variation is performed after the symbol variation game is started, and the symbol of deviation is displayed on the special symbol display H1 after five seconds from the start. At the same time, a combination of symbols that is out of the decoration is displayed.

  As described above, in the case where the symbol variation game is performed based on the variation pattern P1 for the offending effect and in the case where the symbol variation game is performed based on the variation pattern P9, the contents of the effect of the display effect on the variable display H2, The variation time of a decorative drawing, the display result of a decorative drawing, etc. are the same, and only the display result of a special drawing and the variation time of a special drawing are different. For this reason, when a symbol variation game is played based on the variation pattern P9, the player determines whether the symbol variation game is a big hit 2R, a small hit, or a loss from the contents of the effect on the variable display H2. It is indistinguishable.

  In addition, the ROM 27b stores the effect patterns in the jackpot game when the symbol variation game becomes the jackpot 15R, classified into an opening effect, a round effect, and an ending effect. The round effect is an effect indicating how many rounds are being executed. The ROM 27b stores the effect patterns in the jackpot game when the symbol variation game becomes the jackpot 2R, classified into an opening effect, a round effect, and an ending effect. The round effect is an effect indicating how many rounds are being executed. Note that the effect pattern in the big hit game when the symbol variation game becomes the big hit 2R is the same as the effect pattern in the small hit game when the symbol variation game becomes the small hit. For this reason, it is difficult for the player to distinguish from the contents of the effect the big hit game when the symbol variation game is 2R and the small hit game when the symbol variation game is the small hit.

  In addition, the big hit determination value is stored in the ROM 27b. The big hit determination value is a determination value used in the internal lottery to determine whether or not the big hit, and is determined from numerical values (all 631 integers from 0 to 630) that the random number for winning determination can take. The number of jackpot determination values differs depending on whether or not the probability variation state is given. The number of jackpot determination values in the probability variation state (10 in this embodiment) is the jackpot determination value in the normal state. Is set to be larger than the number (2 in this embodiment). The ROM 27b stores a small hit determination value. The small hit determination value is a determination value used in an internal lottery for determining whether or not a small hit is made, and is determined from numerical values that can be taken by a random number for hit determination. Note that the number of small hit determination values (four in this embodiment) is set to be larger than the number of big hit determination values in the normal state (two in this embodiment).

  The ROM 27b stores special figure determination values used when determining the type of special figure ([0] to [2] in the present embodiment) that becomes a big hit symbol when the big hit is determined. In the special figure determination value, a predetermined number of numerical values that can be taken by the special figure distribution random numbers are distributed. In this embodiment, by determining a special figure at the time of determining the jackpot of the internal lottery, it is determined whether or not to give a probability change state after the jackpot game ends. Then, the main CPU 27a compares the special figure distribution random number with the special figure judgment value when the big hit is determined (when it is affirmed by the big hit judgment), and the big hit symbol ([0] to [[ 2]). On the other hand, when the small hit is determined (when the big hit determination is negative and the small hit determination is affirmative), the small hit symbol ([3]) by the special figure is determined. On the other hand, at the time of determination of the loss (when negative in the big hit determination and the small hit determination), the symbol of the loss ([-]) by the special figure is determined. The RAM 27c stores various information (such as various random values) that can be appropriately rewritten during the operation of the pachinko machine 10.

  The main CPU 27a executes various processes such as a winning process and a variation pattern determining process based on the main control program. First, the winning process will be described with reference to FIG.

  The main CPU 27a determines whether or not a game ball winning is detected at predetermined time intervals (step S11). That is, the main CPU 27a determines whether or not a detection signal output from the start winning device constituted by the start winning port 22 and the start port sensor SE1 is input. When the determination result is negative (when no winning is detected), the main CPU 27a ends the winning process. On the other hand, when the determination result is affirmative (when winning detection is present), the main CPU 27a determines whether or not the number of reserved storage stored in the RAM 27c is less than the upper limit (4 in the present embodiment) (step). S12). If this determination result is negative (holding memory count = 4), the main CPU 27a ends the winning process.

  On the other hand, if this determination result is affirmative (if the number of stored storages is less than 4), the main CPU 27a adds “1” (+1) to the stored storage number stored in the RAM 27c and rewrites the stored stored number (step S13). ). Subsequently, the main CPU 27a reads and acquires the value of the random number for hit determination from the RAM 27c, and sets the read value of random number for hit determination in a predetermined storage area of the RAM 27c associated with the reserved storage number (step). S14). Further, the main CPU 27a acquires the value of the special figure distribution random number from the RAM 27c, and sets the read value of the special figure distribution random number in a predetermined storage area of the RAM 27c associated with the reserved storage number ( Step S14). The hit determination random number and the special figure distribution random number are random numbers that are sequentially updated at predetermined intervals by the main CPU 27a, and the main CPU 27a sets the updated value in the setting area of the RAM 27c before the update. The value of is rewritten. Then, the main CPU 27a ends the winning process.

Next, the variation pattern determination process will be described with reference to FIG.
The main CPU 27a determines whether or not the symbols (special illustrations and decorations) are being displayed in a variable manner and whether or not a special game (big hit game or small hit game) is in progress (step S21). When the determination result of step S21 is affirmative (when the symbol variation game is being played or when the special game is being played), the main CPU 27a ends the variation pattern determination process. On the other hand, if the determination result in step S21 is negative (when the symbol variation game is not being played and the special game is not being played), the main CPU 27a determines whether or not the number of reserved memories is greater than “0” at predetermined time intervals ( Step S22). If the determination result of step S22 is negative (the number of stored memories = 0), there is no pending symbol variation game, and the main CPU 27a ends the variation pattern determination process.

  On the other hand, when the determination result of step S22 is affirmative (when the number of stored storages> 0), the main CPU 27a stores the value of the random number for hit determination stored in the RAM 27c in association with the number of stored storages in the ROM 27b. It is determined whether or not the jackpot determination value coincides with the jackpot determination value (step S23). In the present embodiment, the jackpot determination value is changed depending on whether or not the probability variation state is given. In the normal state (low probability), the probability that the determination result of the jackpot determination is affirmative (hit probability) is 2/631, and in the probability variation state (high probability), the determination of the jackpot determination The probability that the result is affirmative (hit probability) is 10/631. Further, the main CPU 27a subtracts “1” from the reserved storage number (−1), and then obtains the value of the hit determination random number and the special figure distribution random number stored in association with the reserved storage number. It has become.

  When the determination result of the jackpot determination is affirmative (in the case of a jackpot), the main CPU 27a reads the value of the special figure distribution random number stored in the RAM 27c in association with the reserved storage number. Then, the main CPU 27a determines a final stop symbol to be finalized and stopped on the special symbol display H1 from among the jackpot symbols based on the special symbol based on the value of the random number for special symbol distribution (step S24). In the present embodiment, the jackpot symbol based on the special figure is any one of [0] to [2], and the main CPU 27a determines the special figure from these. In the present embodiment, special figures [0] and [1] are special figures showing a big hit 15R, and special figures [2] are special figures showing a big hit 2R. Further, the special figure [0] is a special figure showing a non-probable variation big hit, and the special figures [1] and [2] are special figures showing a probable variation big hit. In step S24, the main CPU 27a determines the special figure [0] with a probability of 4/10, determines the special figure [1] with a probability of 5/10, and determines the special figure [2] with a probability of 1/10. ] Is decided.

  Thereafter, the main CPU 27a determines a variation pattern from the variation patterns for the big hit effect based on the big hit symbol (step S25). That is, when the big hit symbol is a special figure [0] [1] indicating the big hit 15R, the main CPU 27a determines a fluctuation pattern from the fluctuation patterns (P4, P6, P8) for the big hit 15R effect.

  Specifically, as shown in the fluctuation pattern distribution table T1 shown in FIG. 7A, random numbers for distribution pattern distribution are allocated to the variation patterns P4, P6, and P8 for the big hit 15R effect. . The random numbers for distribution pattern distribution are 100 whole numbers from “0 to 99”. The variation pattern distribution random number is a random number that is sequentially updated by the main CPU 27a at predetermined intervals. The main CPU 27a sets the updated value in the setting area of the RAM 27c and rewrites the value before the update. In the process of step S25, the main CPU 27a acquires a random number for fluctuation pattern distribution from the RAM 27c when the big hit symbol is a special figure [0] [1] indicating the big hit 15R, and refers to the fluctuation pattern distribution table T1. Then, the variation pattern for the big hit 15R effect is determined.

  When the jackpot symbol is the special chart [2] indicating the jackpot 2R, the main CPU 27a determines a variation pattern from the variation patterns (P5, P9) for the jackpot 2R effect. Specifically, as shown in the fluctuation pattern distribution table T2 shown in FIG. 7B, random numbers for distribution pattern distribution are allocated to the variation patterns P5 and P9 for the big hit 2R effect. In the process of step S25, when the big hit symbol is the special figure [2] indicating the big hit 2R in the process of step S25, the main CPU 27a acquires the random number for variation pattern distribution from the RAM 27c, and refers to the variation pattern distribution table T2 to determine the big hit 2R. A variation pattern for production is determined.

  The main CPU 27a that has determined the variation pattern and the final stop symbol executes various processes relating to the symbol variation game, such as outputting a predetermined control command to the overall control board 28 (sub CPU 28a) at a predetermined timing (step S26). . Specifically, the main CPU 27a first outputs a variation pattern designation command that designates a variation pattern and instructs the start of symbol variation. At the same time, the main CPU 27a controls the display content of the special figure display H1 so that the special figure starts to fluctuate.

  Next, the main CPU 27a outputs a special symbol designation command for designating the final stop symbol. Thereafter, the main CPU 27a displays the display contents of the special figure display H1 so as to display the final stop symbol determined based on the fluctuation time of the special figure in the special figure display H1 determined in the designated fluctuation pattern. To control. In addition, the main CPU 27a instructs the stoppage of the decorative drawing based on the change time of the decorative drawing in the variable display H2 defined in the specified change pattern, and displays all the symbols for the fixed stop display of the symbol combination. Output a stop command. Thereafter, the main CPU 27a ends the variation pattern determination process.

  On the other hand, if the determination result of the big hit determination in step S23 is negative (not the big hit), the main CPU 27a determines whether or not the value of the random number for hit determination matches the small hit determination value stored in the ROM 27b. Then, a small hit determination is performed (step S27). The probability of winning a small hit is 4/631. When the determination result of step S27 is affirmative (in the case of small hit), the main CPU 27a determines the special figure [3] indicating the small hit as the final stop symbol (step S28). Then, the main CPU 27a determines a variation pattern from the variation patterns P5 and P9 for the small hit effect (step S29). Specifically, since the variation patterns P5 and P9 are shared even when the jackpot is 2R, the main CPU 27a determines the variation pattern by sharing the variation pattern distribution table T2. That is, in the process of step S29, the main CPU 27a acquires a random number for variation pattern distribution from the RAM 27c, and determines the variation pattern for the small hit effect with reference to the variation pattern distribution table T2. Thereafter, the main CPU 27a proceeds to the process of step S26.

  On the other hand, when the determination result of the big hit determination of step S27 is negative (when it is not the small hit), the main CPU 27a performs a reach determination for determining whether or not to perform a reach effect (step S30). In the present embodiment, the probability that the determination result of reach determination is affirmative (probability of performing reach production) is 1/12 regardless of whether or not the probability variation state is given. Therefore, the player cannot determine whether or not a certain variation state is given based on the appearance rate of the reach effect that is lost.

  When the determination result of the reach determination in step S30 is affirmative (when a reach effect is performed), the main CPU 27a determines a special figure [-] indicating a loss as a final stop symbol (step S31). Then, the main CPU 27a determines a variation pattern from among the variation patterns P3, P5, and P7 for the outlier reach effect (step S32). Specifically, as shown in the variation pattern distribution table T3 shown in FIG. 7C, random numbers for distribution pattern distribution are allocated to the variation patterns P3, P5, and P7 for the outlier reach effect, respectively. . In the process of step S32, the main CPU 27a obtains a random number for variation pattern distribution from the RAM 27c, and determines a variation pattern for the reach reach effect by referring to the variation pattern distribution table T3. Thereafter, the main CPU 27a proceeds to the process of step S26.

  On the other hand, when the determination result of the reach determination in step S30 is negative (when the reach effect is not performed), the main CPU 27a determines the special figure [-] indicating the detachment as the final stop symbol (step S33). Then, the main CPU 27a determines a variation pattern from the variation patterns P1 and P2 for the offending effect (step S34). Specifically, as shown in the fluctuation pattern distribution table T4 in FIG. 7D, when the number of reserved memories is 0 or 1, the main CPU 27a determines the fluctuation pattern P1 and the number of reserved memories is 2 or 3. In this case, the fluctuation pattern P2 is determined. Thereafter, the main CPU 27a proceeds to the process of step S26.

  When the main CPU 27a determines the jackpot 15R, the main CPU 27a starts controlling the jackpot game when the jackpot 15R is reached after the symbol variation game based on the determined variation pattern, and controls the central control board 28 (the central CPU 28a). On the other hand, a predetermined control command is output at a predetermined timing. Specifically, the main CPU 27a first outputs an opening command for designating an effect pattern in the opening effect. Next, the main CPU 27a outputs a round command for designating an effect pattern in each round effect at the start of each round game. At that time, the main CPU 27a opens and closes the grand prize winning door 24 for each round game. Then, at the end of the final round, the main CPU 27a outputs an ending command for designating an effect pattern in the ending effect, and ends the big hit game. At that time, the main CPU 27a sets various flags based on the special figure (final stop symbol) displayed at the end of the symbol variation game.

  Specifically, the main CPU 27a sets a probability change flag indicating that the gaming state is a probability change state when the special figure [1] is displayed as the final stop symbol. Further, when the special CPU [0] is displayed as the final stop symbol, the main CPU 27a clears the probability change flag to indicate that the gaming state is the normal state. Each flag is stored in a predetermined storage area of the RAM 27c.

  Also, when the main CPU 27a determines the jackpot 2R, after the end of the symbol variation game based on the determined variation pattern, the main CPU 27a starts the control of the jackpot game when the jackpot 2R is reached, and controls the central control board 28 (the central CPU 28a). On the other hand, a predetermined control command is output at a predetermined timing. Specifically, the main CPU 27a first outputs an opening command for designating an effect pattern in the opening effect. Next, the main CPU 27a outputs a round command for designating an effect pattern in each round effect at the start of each round game. At that time, the main CPU 27a opens and closes the grand prize winning door 24 for each round game. Then, at the end of the final round, the main CPU 27a outputs an ending command for designating an effect pattern in the ending effect, and ends the big hit game. At that time, the main CPU 27a sets various flags based on the special figure (final stop symbol) displayed at the end of the symbol variation game. Specifically, the main CPU 27a displays the special figure [2] as the final stop symbol, and therefore sets a probability change flag indicating that the gaming state is a probability change state.

  When the main CPU 27a determines the small hit, the main CPU 27a starts controlling the small hit game after the end of the symbol variation game based on the determined variation pattern, and sends a predetermined control command to the overall control board 28 (the overall CPU 28a). Is output at a predetermined timing. Specifically, the main CPU 27a first outputs an opening command for designating an effect pattern in the opening effect. Next, the main CPU 27a outputs a round command for designating an effect pattern in each round effect at the start of each round game. At that time, the main CPU 27a opens and closes the grand prize winning door 24 for each round game. Then, at the end of the final round, the main CPU 27a outputs an ending command for designating an effect pattern in the ending effect, and ends the big hit game. At the end of the small hit game, the main CPU 27a does not newly set various flags.

  As described above, the main CPU 27a of the present embodiment serves as a hit determination unit that determines whether or not the symbol variation game is a win (big hit or small win). The main CPU 27a serves as random number extraction means for extracting (acquiring) a hit determination random number. Further, the main CPU 27a serves as a probability change determining means for determining whether or not to give a probability variation state. Further, the main CPU 27a serves as a variation pattern determining means for selecting a variation pattern. The main CPU 27a serves as reach determination means for performing reach determination.

Next, the overall control board 28 will be described with reference to FIG.
The overall control board 28 is provided with an overall CPU 28a. A ROM 28b and a RAM 28c are connected to the overall CPU 28a. The overall CPU 28a updates various random number values at predetermined intervals, stores (sets) the updated values in the setting area of the RAM 28c, and rewrites the values before the update. The ROM 28b stores an overall control program for overall control of the display control board 29, the lamp control board 30, and the sound control board 31.

  The overall CPU 28a executes various controls based on the overall control program. For example, the overall CPU 28a outputs the input variation pattern designation command to the control boards 29 to 31. Further, when the general CPU 28a inputs the special symbol designation command and the variation pattern designation command, the overall CPU 28a determines the symbol combination of the decorative symbols to be displayed on the variable display H2 based on the variation pattern designated by the final stop symbol and the variation pattern designation command. To do.

  Specifically, when the big hit 15R effect variation patterns P4, P6, and P8 are designated, the overall CPU 28a determines the combination of decorative symbols as the same type of decorative symbols in all rows. At this time, the overall CPU 28a determines the type of decorative symbol based on the special symbol which is the final stop symbol designated by the special symbol designation command. Specifically, the overall CPU 28a, when it is a special figure [1] (when it is a probable variation) or when the designated special figure is [0] (when it is a non-probable variation), all the symbols in the column The combination of decorative symbols is determined so that the symbols are of the same type. For this reason, the player cannot determine whether or not a certain change state has been given from the combination of decorative symbols.

  Further, when the variation patterns P3, P5, and P7 for the outreach reach effect, the big hit 2R effect, or the small hit effect are designated, the general CPU 28a uses the same type of symbols in the left column and the right column. The symbol combination of the decorative symbols is determined so that the symbols in the middle row do not match the symbols in the left and right columns.

  In addition, when the variation patterns P1, P2, and P9 for the off-line effect, the big hit 2R effect, or the small hit effect are designated, the overall CPU 28a displays the decorative symbols so that the symbols on the left column and the right column are different. Determine the combination. Then, the overall CPU 28a outputs a decorative symbol designation command for designating the decided symbol combination to the display control board 29.

  Further, the overall CPU 28a sets a probability variation state flag indicating that a certain probability variation state has been assigned based on a special diagram designated by a special symbol designation command. Specifically, when the designated special figure is [1] or [2], the overall CPU 28a sets a probability variation state flag and rewrites the RAM 28c. When the designated special figure is [0], the overall CPU 28a clears the probability variation state flag and rewrites the RAM 28c.

  In addition, when the overall CPU 28a receives the all symbols stop command, the overall CPU 28a outputs the all symbols stop command to the control boards 29 to 31. When the general CPU 28a inputs an opening command, each round command, or an ending command, the overall CPU 28a outputs each command to each control board 29-31.

Next, the display control board 29 will be described with reference to FIG.
The display control board 29 is provided with a sub CPU 29a. A ROM 29b and a RAM 29c are connected to the sub CPU 29a. A variable display H2 is connected to the display control board 29 (sub CPU 29a). The ROM 29b stores an effect control program for controlling the display content of the variable display H2. The ROM 29b stores various image data (image data such as symbols, various background images, characters and characters). The RAM 29c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The sub CPU 29a executes various controls based on the display effect control program. For example, when the sub CPU 29a inputs a control command from the overall control board 28 (overall CPU 28a), the sub CPU 29a performs control according to the input control command based on the display effect control program. For example, when the opening command is input, the sub CPU 29a controls the display content of the variable display H2 so as to execute the opening effect. Further, when the sub CPU 29a inputs a round command, the sub CPU 29a controls the display content of the variable display H2 so as to execute a round effect. In addition, when the ending command is input, the sub CPU 29a controls the display content of the variable display H2 so as to execute the ending effect.

  Further, for example, when the sub CPU 29a inputs the variation pattern designation command, the variable display H2 is configured to display the variation symbol and start the symbol variation game based on the variation pattern designated by the variation pattern designation command. Control display content. When the sub CPU 29a inputs the all symbol stop command, the sub CPU 29a controls the display content of the variable display H2 so as to display the symbol combination of the ornament symbol designated by the inputted ornament symbol designation command. With these controls, the variable display device H2 starts the symbol variation game based on the variation pattern, and stops displaying the ornament when the variation time of the ornament designated by the variation pattern has elapsed.

  When the symbol variation game is performed based on the variation pattern P4, P6, P8 for the big hit 15R effect, the indicators H1 and H2 simultaneously start symbol variation, and the reach state is formed in the variable indicator H2. Reach production is performed, and the indicators H1 and H2 simultaneously stop and display the symbols when the fluctuation time has elapsed. That is, in the special symbol display H1, the variation of the symbol is continued until the variation time has elapsed after the variation of the symbol is started, and the display effect of the content that gives the player a sense of expectation for the big hit such as the reach effect is variable. This is performed only by the display H2.

  Further, when the symbol variation game is performed based on the variation pattern P5, the indicators H1 and H2 start symbol variation at the same time, the reach state is formed in the variable indicator H2, the reach effect is performed, and the variation time is changed. Each indicator H1 and H2 stops and displays the symbols at the same time. At this time, on the variable display H2, the out-of-place symbol combination based on the decorative drawing is displayed in a fixed stop state. However, even when the symbol variation game is performed based on the variation pattern P5 and the shifted symbol combination is displayed on the variable display H2, the main CPU 27a determines the special symbol [2] as the final stop symbol. In such a case, the special figure [2] is displayed on the special figure display H1 in a fixed stop state. Similarly, when the main CPU 27a has determined the special figure [3], the special figure [3] is confirmed and stopped on the special figure display H1, and the special figure [-] is determined. In such a case, the special figure [-] is displayed on the special figure display H1 in a fixed stop state.

  Further, when the symbol variation game is performed based on the variation pattern P9 or the variation pattern P1, the indicators H1 and H2 simultaneously start the variation of the symbol, the normal variation is performed, and when the variation time of the decorative diagram has elapsed (the symbol At 12 seconds after the start of the change game), the variable display H2 displays the symbol combination that is out of the decorative drawing in a fixed stop display. However, when the symbol variation game is performed based on the variation pattern P1, unlike the case where the symbol variation game is performed based on the variation pattern P9, the main CPU 27a does not change the decoration variation time (from the start of the symbol variation game). 12 seconds later) [-], which is the final stop symbol of the special figure, is displayed on the special figure display H1 in a fixed stop manner.

  On the other hand, when the symbol variation game is performed based on the variation pattern P9 and the main CPU 27a has determined the special symbol [2] as the final stop symbol, the special symbol specified by the variation pattern P9 is displayed. In accordance with the variation time, two seconds after the start of the symbol variation game, the special figure display H1 is made to stop and display the special figure [2]. Similarly, when the symbol variation game is played based on the variation pattern P9 and the main CPU 27a has determined the special symbol [3] as the final stop symbol, the special symbol specified by the variation pattern P9. In accordance with the change time, the special figure [3] is displayed on the special figure display H1 in a fixed stop state after 2 seconds from the start of the symbol fluctuation game.

  If the main CPU 27a has determined the variation pattern P9, immediately after the end of the symbol variation game on the special symbol display H1 (after 2 seconds from the beginning of the symbol variation game), immediately the big hit game or small moment at the time of the big hit 2R A hit game is started. This big hit 2R big hit game or small hit game ends 10 seconds after the start. That is, 12 seconds after the start of the symbol variation game, the big hit 2R big hit game or the small hit game ends. Then, the sub CPU 29a of the display control board 29 gives priority to the symbol combination game when the symbol combination game based on the variation pattern P9 has not ended even when the big hit 2R big hit game or the small hit game is performed. It is like that. That is, even if the sub CPU 29a receives an opening command, a round command, and an ending command, the sub CPU 29a is in a symbol combination game based on the variation pattern P9. Display effects related to games are not performed.

  For this reason, when the player is concentrating on display effects (such as a symbol combination game) on the variable display H2, the player is unaware of the big hit game or the small hit game at the big hit 2R. Therefore, when the player is concentrated on the display effect (such as the symbol combination game) on the variable display H2, the symbol variation game is performed based on the variation pattern P9, and the big hit game at the time of the big hit 2R ends. Even if the probability variation state is given, it is difficult to notice, and it is easy to recognize that the symbol variation game is lost based on the variation pattern P1. In addition, when the symbol variation game is performed based on the variation pattern P9 and the big hit game or the small hit game at the big hit 2R is performed, the display effect of the big hit game or the small hit game at the big hit 2R is performed. Although the big prize opening door 24 opens and closes, the player may notice a big hit game or a small hit game when the big hit is 2R. However, the display effect of the big hit game or the small hit game at the time of the big hit 2R is not performed, but the opening / closing timing of the big winning opening door 24 is the same, so that the player can determine whether or not the probable change state has been given. It cannot be recognized.

  In the present embodiment, when the main CPU 27a determines a predetermined variation pattern, a background switching effect for changing and displaying the background image of the variable display H2 is performed immediately before the end of the symbol combination game on the variable display H2. It has become. This will be described in detail below.

First, the background setting process related to the background switching effect executed by the overall CPU 28a will be described with reference to FIG.
When the general CPU 28a inputs the variation pattern designation command, the general CPU 28a refers to the RAM 28c and confirms the background flag indicating the background image to be displayed on the variable display H2 (step S100). In the present embodiment, there are four types of background images, background images A to D. The background image A is a background showing a night sky as shown in FIG. 9A, and the background image B is a background showing a crescent moon floating in the night sky as shown in FIG. 9B. It is. In addition, the background image C is a background showing a half moon floating in the night sky as shown in FIG. 9C, and the background image D is a full moon in the night sky as shown in FIG. 9D. It is a background that shows a floating situation. If “0” is set in the background flag stored in the predetermined area of the RAM 28c, it indicates that the background image A is displayed. If “1” is set in the background flag, the background image B is displayed. Further, when “2” is set in the background flag, it indicates that the background image C is displayed, and when “3” is set in the background flag, it indicates that the background image D is displayed. Show.

  Then, based on the confirmed background flag, the overall CPU 28a sets a predetermined background area of the RAM 28c so as to output a current background designation command for designating a background image of the variable display H2 to be displayed to the display control board 29 (step). S101). Thereby, in the output process, the overall CPU 28a outputs the current background designation command to the display control board 29 at the start of the symbol variation game at the start of the symbol variation game (that is, at the time of the variation pattern designation command output).

  Next, the overall CPU 28a determines whether or not the variation pattern P5 is designated by the variation pattern designation command (step S102). When the determination result of step S102 is affirmative (when the variation pattern P5 is specified), the overall CPU 28a determines whether or not the special symbol designated by the input special symbol designation command is an outlier symbol [-]. (Step S103). In other words, the overall CPU 28a determines whether or not a predetermined deviation reach effect variation pattern P5 has been designated in the processing of step S102 and step S103.

  If the determination result in step S103 is affirmative (if the symbol is out of order), the overall CPU 28a refers to the RAM 28c and determines whether or not the probability change state flag is set, that is, whether or not the gaming state is a probability change state. Is determined (step S104). When the determination result in step S104 is affirmative (when it is in the probability variation state), the overall CPU 28a acquires the background change random number from the RAM 28c, refers to the background transition table T100 in the probability variation state, and based on the acquired background modification random number. Then, the background image to be changed is selected (step S105).

  The background change random numbers are 100 whole numbers from “0 to 99”. The background change random number is a random number that is sequentially updated every predetermined cycle by the overall CPU 28a, and the overall CPU 28a rewrites the value before update by setting the updated value in the setting area of the RAM 28c.

  Further, in the background transition table T100 in the probability changing state, each background image A that is stored in the ROM 28b and is selected as the background image to be changed for each of the background images A to D, as shown in FIG. The selectivity of ~ D is shown. That is, in the background transition table T100, the background image selected as the background image to be changed is associated with each of the background images A to D, and background change random numbers are assigned to the background image to be changed. .

  Specifically, background image B is associated with background image A as a background image to be changed, and a background change random number is assigned to each of background images B to D. In addition, background images A, C, and D are associated with the background image B as background images to be changed, and background change random numbers are assigned to the background images A, C, and D, respectively. The background image C is associated with background images A, B, and D as background images to be changed, and background change random numbers are assigned to the background images A, B, and D, respectively. The background image D is associated with background images A to C as background images to be changed, and background change random numbers are assigned to the background images A to C, respectively.

  The selection rate is determined by the number of assigned items. That is, when the background image A is displayed, the selection rate of the background image B that is the background image to be changed is 14/100. When the background image A is displayed, the selection rate of the background image C that is the background image to be changed is 14/100. When the background image A is displayed, the selection rate of the background image D that is the background image to be changed is 72/100. When the background image B is displayed, the selection rate of the background image A that is the background image to be changed is 14/100. When the background image B is displayed, the selection rate of the background image C that is the background image to be changed is 14/100. When the background image B is displayed, the selection rate of the background image D that is the background image to be changed is 72/100.

  When the background image C is displayed, the selection rate of the background image A that is the background image to be changed is 14/100. When the background image C is displayed, the selection rate of the background image B that is the background image to be changed is 14/100. When the background image C is displayed, the selection rate of the background image D that is the background image to be changed is 72/100. When the background image D is displayed, the selection rate of the background image A that is the background image to be changed is 72/100. When the background image D is displayed, the selection rate of the background image B that is the background image to be changed is 14/100. When the background image B is displayed, the selection rate of the background image C that is the background image to be changed is 14/100.

  Accordingly, in the process of step S105, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T100, and changes the background image to which the background change random number value acquired from the RAM 28c is distributed. Select. That is, the overall CPU 28a specifies the current background image from the background flag, refers to the background transition table T100, and selects the background image to be changed based on each selection rate of the background image to be selected. Further, in the process of step S105, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S105 is completed, the overall CPU 28a changes the background image and a predetermined storage area of the RAM 28c so that the display control board 29 outputs a background switching designation command for designating the selected background image. (Step S106). Thereby, in the output process, the overall CPU 28a determines whether or not the decoration drawing has been temporarily displayed from the variation time of the decoration drawing specified by the variation pattern P5. If the determination result is affirmative, display control of the background switching designation command is performed. Output to the substrate 29. Specifically, the overall CPU 28a measures the elapsed time from the time when the variation pattern designation command is output, and has it reached the time at which the decorative drawing is temporarily displayed (29000 ms after the start of the symbol variation game in this embodiment)? If it is reached, a background switching designation command is output to the display control board 29.

  On the other hand, when the determination result of step S104 is negative (when the probability variation state is not established), the overall CPU 28a obtains the background change random number from the RAM 28c, refers to the background transition table T200 in the non-probability variation state (normal state), and obtains it. Based on the background change random number, the background image to be changed is selected (step S107).

  The background transition table T200 in the non-probable change state is stored in the ROM 28b, and as shown in FIG. The selectivity of D is shown. That is, in the background transition table T200, a background image selected as a change destination background image is associated with each of the background images A to D, and a background change random number is assigned to the change destination background image. .

  Specifically, background image B is associated with background image A as a background image to be changed, and a background change random number is assigned to each of background images B to D. In addition, background images A, C, and D are associated with the background image B as background images to be changed, and background change random numbers are assigned to the background images A, C, and D, respectively. The background image C is associated with background images A, B, and D as background images to be changed, and background change random numbers are assigned to the background images A, B, and D, respectively. The background image D is associated with background images A to C as background images to be changed, and background change random numbers are assigned to the background images A to C, respectively.

  Then, the selection rate of each background image to be changed in the uncertain change state is indicated by the distributed number. That is, when the background image A is displayed, the selection rate of the background image B that is the background image to be changed is 37/100. When the background image A is displayed, the selection rate of the background image C that is the background image to be changed is 59/100. When the background image A is displayed, the selection rate of the background image D that is the background image to be changed is 4/100. When the background image B is displayed, the selection rate of the background image A that is the background image to be changed is 29/100. When the background image B is displayed, the selection rate of the background image C that is the background image to be changed is 67/100. When the background image B is displayed, the selection rate of the background image D that is the background image to be changed is 4/100.

  When the background image C is displayed, the selection rate of the background image A that is the background image to be changed is 36/100. When the background image C is displayed, the selection rate of the background image B that is the background image to be changed is 60/100. When the background image C is displayed, the selection rate of the background image D that is the background image to be changed is 4/100. When the background image D is displayed, the selection rate of the background image A that is the background image to be changed is 17/100. When the background image D is displayed, the selection rate of the background image B that is the background image to be changed is 51/100. When the background image B is displayed, the selection rate of the background image C that is the background image to be changed is 32/100.

  Accordingly, in the processing of step S107, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and changes the background image to which the background change random number value acquired from the RAM 28c is distributed. Select. That is, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and selects the background image to be changed based on the selection rates of the background images to be changed. In step S107, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S107 ends, the overall CPU 28a proceeds to the process of step S106, and causes the display control board 29 to output a background switching designation command for designating the change of the background image and the background image of the selected change destination. As described above, it is set in a predetermined storage area of the RAM 28c.

  On the other hand, when the determination result of step S102 is negative (when the variation pattern P5 is not specified) and when the determination result of step S103 is negative (a case of a big hit symbol [2] or a small hit symbol [3]) ) The overall CPU 28a ends the background setting process.

  As described above, when the fluctuation pattern for the outlier reach effect (the fluctuation pattern P5 in this embodiment) is input, the overall CPU 28a changes and displays the background image. Then, the overall CPU 28a refers to the background transition table T100 at the time of the probability variation state, and selects the background image of the modification destination based on each selection rate of the background image of the modification destination at the probability variation state. On the other hand, in the non-probability change state, the overall CPU 28a refers to the background transition table T200 in the non-probability change state and selects the change-destination background image based on each selection rate of the change-destination background image. That is, the selection rate of the background image to be changed is changed according to whether or not the state is a certain change state.

  Specifically, as shown in FIG. 10A, in the probability variation state, when any of the background images A to C is displayed, the background image D is most easily selected as the background image to be changed. When the background image D is displayed, the background image A is most easily selected as the background image to be changed. For this reason, when the general CPU 28a executes the background switching effect, for example, the background image is changed as A → D → A → D → A → B → D → A → D → A → D → C → D → A. Will be displayed. That is, in the probability changing state, the background image A and the background image D are easily changed and displayed.

  On the other hand, as shown in FIG. 10B, when any of the background images A to C is displayed in the uncertain change state, the background image D is most difficult to be selected as the background image to be changed. there. Further, when the background image D is displayed, the background image B and the background image C are slightly more easily selected than the background image A. For this reason, when the general CPU 28a executes the background switching effect, for example, the background image is changed as A → C → B → C → A → B → C → B → C → B → C → D → B → C. and it is displayed. That is, in the probability changing state, background images other than the background image D are likely to be repeatedly changed and displayed.

  Therefore, when the background image is changed many times, the player can guess to some extent whether or not the player is in the probability change state from the change mode. On the other hand, the background image D may be selected even in the non-probability change state, and conversely, the background image B and the background image C may be selected even in the probability change state. For this reason, even if the background image is changed several times, it is difficult for the player to make an accurate determination. For this reason, the player can continue the game.

Next, background switching processing related to the background switching effect executed by the display control board 29 (sub CPU 29a) will be described with reference to FIG.
When the sub CPU 29a inputs the current background designation command together with the variation pattern designation command, whether or not the background image designated by the current background designation command matches the background image indicated by the current display background confirmation flag stored in the RAM 29c. Is determined (step S111). The current display background flag is a flag indicating the background image currently displayed on the variable display H2, and when the current display background flag is set to “0”, the background image A is displayed. When “1” is set in the current display background flag, it indicates that the background image B is displayed. If “2” is set in the current display background flag, it indicates that the background image C is displayed. If “3” is set in the current display background flag, the background image D is displayed. It shows that.

  If the determination result in step S111 is negative, the sub CPU 29a changes the background image currently displayed on the variable display H2 to the background image designated by the current background designation command at the start of the symbol combination game (design variation game). The display content of the variable display H2 is controlled so as to be changed and displayed (step S112). At the same time, the sub CPU 29a rewrites the RAM 29c so that the current display background flag indicates the background image designated by the current background designation command (step S113).

  Then, after the processing of step S113 is completed or when the determination result of step S111 is affirmative, the sub CPU 29a determines whether or not a background switching designation command has been input (step S114). If the determination result in step S114 is affirmative, the sub CPU 29a changes the background image currently displayed on the variable display H2 to the background image designated by the background switching designation command and displays it. Is controlled (step S115). At the same time, the sub CPU 29a rewrites the RAM 29c so that the current display background flag indicates the background image designated by the background switching designation command (step S116), and ends the background switching process. On the other hand, when the determination result of step S114 is negative (when the background switching designation command is not input), the overall CPU 28a ends the background switching process.

  From the above, the sub CPU 29a of the present embodiment serves as background switching means. Further, the sub CPU 29a of the present embodiment serves as background switching correction means. The overall CPU 28a serves as background selection means. The overall CPU 28a serves as a current background instruction unit. The ROM 28b serves as a selection rate storage unit. The RAM 28c serves as the current background storage means. The ROM 29b serves as background image storage means. The RAM 29c serves as an instruction background storage unit. The overall CPU 28a serves as background switching instruction means.

Next, the timing at which the background image is switched in the present embodiment will be described.
FIG. 12 shows the contents of the effect of the symbol variation game on the special symbol display H1 and the effect of the display effect relating to the symbol variation game on the variable display H2 (the symbol combination game) when the variation pattern P5 for the outlier reach effect is determined. It is a time chart of contents. In FIG. 12, the background image A is displayed at the start of the symbol variation game, and the overall CPU 28a is described as changing and displaying the background image B in the background switching process.

  When the main CPU 27a determines the variation pattern P5 based on the premise (time point X1), the main CPU 27a outputs a variation pattern designation command for designating the variation pattern P5 and also executes the symbol variation game based on the variation pattern P5. Controls the display content of. When the sub CPU 29a inputs the variation pattern designation command, the sub CPU 29a controls the display content of the variable display H2 to execute the symbol combination game based on the variation pattern P5 designated by the variation pattern designation command (time point X1). ). Then, the sub CPU 29a starts controlling the display content of the variable display H2 so as to execute the reach effect N and the reach effect SA based on the variation pattern P5 (time point X2). At this time, the sub CPU 29a controls the display content of the variable display H2 so as to change and display the background image to the reach background image based on the variation pattern P5.

  Then, based on the variation pattern P5, the sub CPU 29a controls the display content of the variable display H2 so as to stop and display the combination of decoration drawings and end the reach effect SA (time point X3). At this time, in the output process, the overall CPU 28a outputs the background switching designation command determined (from the premise) in the background setting process. For this reason, at the time point X3, the sub CPU 29a controls the display content of the variable display H2 so as to change and display the background image B designated by the background switching designation command.

  Then, based on the variation pattern P5, the main CPU 27a, after 30 seconds from the start of the symbol variation game, causes the special symbol display H1 to display the final special symbol as a final stop symbol in a fixed stop display (time point X4). At the same time, based on the variation pattern P5, the sub CPU 29a displays a definite symbol combination on the variable display H2 after 30 seconds from the start of the symbol variation game (time point X4).

As described above in detail, the present embodiment has the following effects.
(1) The general CPU 28a executes a background switching effect for changing and displaying the background image when the main CPU 27a determines a predetermined variation pattern regardless of the gaming state. The central CPU 28a selects the background image to be the transfer destination at a selection rate different from the selection rate at the non-probability change state of the background image to be the transfer destination in the probability changing state, and the sub CPU 29a selects the background image selected by the overall CPU 28a. It is displayed on the variable display H2. As a result, there is a high possibility that the type of the background image to be changed is different between the normal state and the probability change state, and the change order of the background image is likely to be changed.

  For example, the background image is changed in the order of A → C → B → C → A → B → C → B → C → B → C → D → B →. When the probability of being changed is high, the background image is in the non-probable state in the order of A → D → A → D → A → B → D → A → D → A → D → C → D →. Is likely to be changed in a different order. For this reason, paying attention to whether or not the change order is likely to be in the probability change state, in order to infer the presence or absence of the probability change state, the player continues the game and displays the background image multiple times. Can be made.

  (2) The overall CPU 28a selects the background image to be changed at a predetermined selection rate, and regardless of which background image is displayed, the other three types of background images are used as the background image to be changed. Since the change order can be selected, the change order in the normal state may be similar to the change order in the probability variation state. For this reason, even in the non-probability change state, if the background image is changed in an order similar to the change order in the probability change state, the player can expect that the probability change state is given. , Can be motivated to continue the game.

  (3) The sub CPU 29a changes and displays the background image on the variable display H2 between the time when the display result of the symbol variation game is temporarily stopped and the time when the fixed stop is displayed. For this reason, during the symbol combination game on the variable display H2, it interferes with an important effect (such as a reach effect) indicating that the game played before the symbol combination by the decorative drawing is temporarily stopped and displayed may be a big hit. There is nothing. Moreover, after the symbol combination by a decorative drawing is once stopped and displayed, the background image is changed and displayed. For this reason, even if the off-set symbol combination is temporarily stopped, if the background image to be changed is a background image that has a high probability of being changed in the probability variation state, it is suggested that the probability variation state is given to the player. And can continue the game. Further, since the tendency of the change order of the background image cannot be determined unless the symbol variation game is executed a plurality of times, the game can be continued by the player.

  (4) The overall CPU 28a changes and displays the background image when the predetermined deviation reach reach variation pattern P5 is determined. When the symbol variation game on the special symbol display H1 is disconnected, the gaming state is not changed, so that the player can easily guess the current gaming state from the changed and displayed background image. In addition, after the symbol variation game is displayed on the special symbol display device H1, the background image is changed and displayed, so that after the symbol variation game is finished, the player may be given a probability variation state. It can be expected and the game can be continued.

  (5) During the reach effect, in the pachinko machine 10 that displays the background image for reach effect and displays the original background image at the end of the reach effect, the sub CPU 29a displays the background image at the timing when the reach effect ends. Changed to display. For this reason, the background image is changed and displayed from the reach effect background image, and it is possible to eliminate a sense of incongruity than when the background image is suddenly changed to a different background image. Further, the sub CPU 29a temporarily displays the shift display result in the symbol variation game, and then changes and displays the background image. Therefore, even if the symbol combination game accompanied by the reach effect is lost, after the symbol variation game ends, The player can be expected to be given a certain probability change state, and the game can be continued.

  (6) The background image selected by the overall CPU 28a provided on the overall control board 28 is stored as a background flag in the RAM 28c, and the overall CPU 28a outputs a current background designation command for designating the background image at the start of the symbol variation game. . Then, the sub CPU 29a of the display control board 29 determines that the background image designated by the current background designation command is different from the background image displayed on the variable display H2, that is, the background image designated by the current background designation command. If the background image indicated by the current display background confirmation flag stored in the RAM 29c is different, the instructed background image is displayed on the variable display H2. For this reason, when there is a deviation between the background image currently stored as being displayed by the overall control board 28 and the background image actually displayed by the display control board 29, the deviation can be corrected. it can. For this reason, when a background image is changed and displayed, it can be changed correctly.

  (7) The overall CPU 28a selects the change destination background image and measures the change timing. For this reason, the processing burden of the main control board 27 and the display control board 29 can be reduced.

  (8) The background image was changed at the timing when the decorative symbols were temporarily displayed. That is, when the processing load relating to the variable display H2 and the display control board 29 is heavy, such as when executing processing related to other effects (for example, processing such as reach effect, symbol variation) in the variable display H2, avoid the background. Changed the image. For this reason, it is possible to reduce a processing load applied at one time, and it is possible to prevent image flickering, display delay, and the like.

(Second embodiment)
Next, a second embodiment embodying the present invention will be described. In addition, the same code | symbol as 1st embodiment is attached | subjected to the structure similar to 1st embodiment, the detailed description and drawing are abbreviate | omitted or simplified.

The background switching effect in the second embodiment will be described in detail.
First, the background setting process related to the background switching effect executed by the overall CPU 28a will be described with reference to FIG.

  When the general CPU 28a inputs the variation pattern designation command, the general CPU 28a refers to the RAM 28c and confirms a background flag indicating a background image to be displayed on the variable display H2 (step S200). Then, based on the confirmed background flag, the overall CPU 28a sets a predetermined background area of the RAM 28c so as to output a current background designation command for designating a background image of the variable display H2 to be displayed to the display control board 29 (step). S201). Thereby, in the output process, the overall CPU 28a outputs the current background designation command to the display control board 29 at the start of the symbol variation game at the start of the symbol variation game (that is, at the time of the variation pattern designation command output).

  Next, the overall CPU 28a determines whether or not the variation pattern P9 is designated by the variation pattern designation command (step S202). That is, the overall CPU 28a determines whether or not the variation pattern P9 for the big hit 2R effect or the variation pattern P9 for the small hit effect is designated. When the determination result in step S202 is affirmative (when the variation pattern P9 is designated), the overall CPU 28a refers to the RAM 28c to determine whether or not the probability variation state flag is set, that is, the gaming state is the certain probability variation state. Whether or not (step S203). When the determination result of step S203 is affirmative (when it is in a probable change state), the overall CPU 28a acquires a background change random number from the RAM 28c, refers to the background transition table T100 in the probable change state, and based on the acquired background change random number. Then, the background image to be changed is selected (step S204). That is, the overall CPU 28a specifies the current background image from the background flag, refers to the background transition table T100, and selects the background image to which the background change random number acquired from the RAM 28c is distributed. In other words, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T100, and selects the change-destination background image based on each selection rate of the selection-destination background image. Further, in the processing of step S204, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S204 is completed, the overall CPU 28a changes the background image and a predetermined storage area of the RAM 28c so that the display control board 29 outputs a background switching designation command for designating the selected background image to be changed. (Step S205). Thereby, in the output process, the overall CPU 28a determines whether the decoration drawing has been stopped and displayed from the variation time of the decoration drawing specified by the variation pattern P9. Output to the substrate 29. Specifically, the overall CPU 28a measures the elapsed time from the time when the variation pattern designation command is output, and has it reached the time at which the decorative drawing is temporarily displayed (11000 ms after the start of the symbol variation game in this embodiment)? If it is reached, a background switching designation command is output to the display control board 29.

  On the other hand, when the determination result of step S203 is negative (when it is not in the probable change state), the overall CPU 28a acquires the background change random number from the RAM 28c, and acquires it by referring to the background transition table T200 in the non-probability change state (in the normal state). Based on the background change random number, the background image to be changed is selected (step S206). That is, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and selects the background image to which the background change random number acquired from the RAM 28c is distributed. In other words, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and selects the background image of the change destination based on each selection rate of the background image of the change destination. Further, in the process of step S206, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S206 ends, the overall CPU 28a proceeds to the process of step S205, and causes the display control board 29 to output a background switching designation command for designating the change of the background image and the background image of the selected change destination. As described above, it is set in a predetermined storage area of the RAM 28c. On the other hand, when the determination result of step S202 is negative (when the variation pattern P9 is not specified), the overall CPU 28a ends the background setting process.

Next, the timing at which the background is switched in the present embodiment will be described.
FIG. 14 is a time chart of the effect contents of the symbol variation game on the special symbol display H1 and the effect content of the display effect (design combination game) related to the symbol variation game on the variable indicator H2 when the variation pattern P9 is determined. is there. In FIG. 14, it is assumed that the background image A is displayed at the start of the symbol variation game, and the overall CPU 28a changes and displays the background image B in the background switching process.

  When the main CPU 27a determines the fluctuation pattern P9 (time point X11), the main CPU 27a outputs a fluctuation pattern designation command for designating the fluctuation pattern P9, and displays the special figure display device H1 so as to execute the symbol fluctuation game based on the fluctuation pattern P9. Control the content. When the sub CPU 29a inputs a variation pattern designation command (time point X11), the sub CPU 29a controls the display content of the variable display H2 to execute the symbol combination game based on the variation pattern P9 designated by the variation pattern designation command. To do.

  Then, based on the variation pattern P9, the main CPU 27a causes the special symbol display H1 to stop and display the special symbol as the final stop symbol two seconds after the symbol variation game starts (time point X12). It should be noted that the sub CPU 29a variably displays the decorative drawing on the variable display H2 after 2 seconds from the start of the symbol variation game based on the variation pattern P9.

  The main CPU 27a outputs an opening command when the symbol variation game is completed on the special symbol display H1 (time point X13). Even if the opening command is input, the sub CPU 29a displays the decorative drawing in a variable manner, so that the variable display of the decorative drawing is given priority and invalidates the opening command. Next, the main CPU 27a outputs a round command for the first round, and opens the grand prize winning door 24 for 0.5 seconds (time point X14). Even if the round command is input, the sub CPU 29a displays the decorative drawing in a variable manner. Therefore, the sub CPU 29a prioritizes the variable display of the decorative drawing and invalidates the round command.

  Next, the main CPU 27a outputs a round command for the second round and opens the grand prize winning door 24 for 0.5 seconds (time point X15). Even if the round command is input, the sub CPU 29a displays the decorative drawing in a variable manner. Therefore, the sub CPU 29a prioritizes the variable display of the decorative drawing and invalidates the round command. Next, the main CPU 27a outputs an ending command (time point X16). Even if the sub CPU 29a inputs the ending command, the decorative drawing is being displayed in a variable manner. Therefore, the sub CPU 29a prioritizes the decorative display of the decorative drawing and invalidates the ending command.

  On the other hand, the sub CPU 29a controls the display content of the variable display H2 so as to temporarily stop and display the combination of decoration drawings based on the variation pattern P9 (time point X17). At this time, in the output process, the overall CPU 28a outputs the background switching designation command determined (from the premise) in the background setting process. Therefore, at the time point X17, the sub CPU 29a controls the display content of the variable display H2 so as to change and display the background image B designated by the background switching designation command. Then, based on the variation pattern P9, the sub CPU 29a controls the display content of the variable display H2 so as to display the fixed symbol combination after the lapse of 12 seconds from the start of the symbol variation game (time point X18).

As described above in detail, this embodiment has the same effects as the effects (1) to (4) and (6) to (8) of the first embodiment, and in addition, the following effects.
(9) Even when the special symbol display game H1 ends with the special symbol display game, the variable display device H2 performs a display effect (symbol combination game) related to the symbol variable game. Then, on the variable display H2, a display effect (symbol combination game) related to the symbol variation game is performed until the big hit 2R big hit game or the small hit game ends, and the sub CPU 29a displays the decorative drawing in a variable manner. , Input of opening command, round command, ending command is invalidated. For this reason, it is easy to conceal the execution of the big hit 2R big hit game or the small hit game from the player, and it is possible to give a certain probability state without noticing the player. And since a player cannot recognize when a certain probability change state is given, he can make a player pay more attention to the change order of a background image, and can improve the interest of a game.

  (10) In the variable display H2, the content of the effect based on the variation pattern P9 is the same as the content of the effect based on the variation pattern P1, and the player performs the operation based on the variation pattern P9 from the content of the effect on the variable display H2. It is difficult to judge whether or not Therefore, even when the symbol combination game is executed based on the variation pattern P1 for the offending effect, the player has not executed the symbol combination game based on the variation pattern P9 for the big hit 2R effect. I can make you think. For this reason, even when the symbol combination game is executed based on the variation pattern P1 for the offending effect, the player is expected to pay attention to the symbol combination game and be given a probability variation state. be able to. The variation pattern P1 is a variation pattern for a loss effect determined when the big hit determination, the small hit determination and the reach determination are negative, and is determined when the big hit determination or the small hit determination is affirmative. The probability of being determined is higher than that of the fluctuation pattern P9 (that is, the appearance rate is high). For this reason, a player can be made to pay attention to a symbol combination game frequently, and the interest of a game improves.

(Third embodiment)
Next, a third embodiment embodying the present invention will be described. In addition, the same code | symbol as 1st embodiment is attached | subjected to the structure similar to 1st embodiment, the detailed description and drawing are abbreviate | omitted or simplified.

The background switching effect in the third embodiment will be described in detail. First, the background setting process related to the background switching effect executed by the overall CPU 28a will be described with reference to FIG.
When the general CPU 28a inputs the variation pattern designation command, the general CPU 28a refers to the RAM 28c and confirms a background flag indicating a background image to be currently displayed on the variable display H2 (step S300). Then, based on the confirmed background flag, the overall CPU 28a sets a predetermined area in the RAM 28c so that a current background designation command for designating the background image of the variable display H2 to be displayed is output to the display control board 29 (step). S301). Thereby, in the output process, the overall CPU 28a outputs the current background designation command to the display control board 29 at the start of the symbol variation game at the start of the symbol variation game (that is, when the variation pattern designation command is output).

  Next, the overall CPU 28a determines whether or not the variation pattern P5 is designated by the variation pattern designation command (step S302). If the determination result in step S302 is affirmative (if the variation pattern P5 is designated), the overall CPU 28a determines that the special symbol designated by the input special symbol designation command is the big hit symbol [2] or the small bonus symbol [3]. ] (Step S303). That is, the overall CPU 28a determines whether or not the big hit 2R effect variation pattern P5 or the small hit effect variation pattern P5 is designated in the processing of step S302 and step S303.

  If the determination result in step S303 is affirmative (if the winning symbol [2] or the small winning symbol [3]), the overall CPU 28a refers to the RAM 28c to determine whether or not the probability variation state flag is set. That is, it is determined whether or not the gaming state is a probable change state (step S304). When the determination result of step S304 is affirmative (when it is in a probable change state), the overall CPU 28a acquires a background change random number from the RAM 28c, refers to the background transition table T100 in the probable change state, and based on the acquired background change random number. Then, the background image to be changed is selected (step S305). In other words, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T100, and selects the background image to which the background change random number acquired from the RAM 28c is distributed. In other words, the overall CPU 28a specifies the current background image from the background flag, refers to the background transition table T100, and selects the background image to be changed based on each selection rate of the background image to be selected. In step S305, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S305 is completed, the overall CPU 28a changes the background image and a predetermined storage area of the RAM 28c so that the display control board 29 outputs a background switching designation command for designating the selected background image to be changed. (Step S306). Thereby, in the output process, the overall CPU 28a determines whether or not a predetermined time has elapsed since the time when the ending command was output (at the time of starting the ending effect). If the determination result is affirmative, the overall CPU 28a displays a background switching designation command. 29. Specifically, the overall CPU 28a measures an elapsed time from the start of the ending effect in the big hit 2R big hit game or the small hit game played after the end of the symbol change game based on the change pattern P5. Then, the overall CPU 28a determines whether or not it has reached 1 second before the end of the ending effect (in this embodiment, 4000 ms after the start of the ending effect), and if so, a background switching designation command is sent to the display control board 29. Output.

  On the other hand, when the determination result of step S304 is negative (when the probability variation state is not established), the overall CPU 28a acquires the background change random number from the RAM 28c, refers to the background transition table T200 in the non-probability variation state, Based on this, a background image to be changed is selected (step S307). That is, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and selects the background image to which the background change random number acquired from the RAM 28c is distributed. In other words, the overall CPU 28a identifies the current background image from the background flag, refers to the background transition table T200, and selects the background image of the change destination based on each selection rate of the background image of the change destination. Further, in the process of step S307, the overall CPU 28a rewrites the value of the background flag so as to indicate the selected background image as the current background image.

  When the process of step S307 ends, the overall CPU 28a proceeds to the process of step S306, and causes the display control board 29 to output a background switching designation command for designating the change of the background image and the background image of the selected change destination. As described above, it is set in a predetermined storage area of the RAM 28c. On the other hand, when the determination result of step S302 is negative (when the variation pattern P5 is not designated) or when the determination result of step S303 is negative (when it is not the big hit symbol [2] or the small hit symbol [3]). The overall CPU 28a ends the background setting process.

Next, the timing at which the background is switched in the present embodiment will be described.
FIG. 16 shows the effect of the symbol variation game on the special symbol display H1 and the display effect relating to the symbol variation game on the variable display H2 when the variation pattern P5 for the small hit effect (or for the big hit 2R effect) is determined. It is a time chart of the production contents of (a symbol combination game). In FIG. 16, the background image A is displayed at the start of the symbol variation game, and the overall CPU 28a is described as changing and displaying the background image B in the background switching process.

  When the main CPU 27a determines the fluctuation pattern P5 (time point X21), the main CPU 27a outputs a fluctuation pattern designation command for designating the fluctuation pattern P5, and displays the special figure display device H1 so that the symbol fluctuation game is executed based on the fluctuation pattern P5. Control the content. When the sub CPU 29a inputs the variation pattern designation command (time point X21), the sub CPU 29a controls the display content of the variable display H2 so that the symbol combination game is executed based on the variation pattern P5 designated by the variation pattern designation command. To do.

  The sub CPU 29a executes the reach effect SA based on the variation pattern P5 (time point X22), and controls the display content of the variable display H2 so as to temporarily stop and display the off symbol combination that is not the jackpot symbol combination (time point). X23). Then, the sub CPU 29a displays a black background image different from any of the background images A to D on the basis of the variation pattern P5, and variably displays so that the off symbol combination is confirmed and stopped after 30 seconds from the start of the symbol variation game. The display content of the device H2 is controlled (time point X24). At the same time (30 seconds after the start of the symbol variation game), the main CPU 27a causes the special symbol display H1 to confirm and stop the special symbol [3] as the final stop symbol based on the variation pattern P5 (time point X24). .

  The main CPU 27a outputs an opening command when the symbol variation game is completed on the special symbol display H1 (time point X25). When the opening command is input, the sub CPU 29a causes the opening effect to be executed on the basis of the opening command because the decoration drawing is not being displayed (time point X25). At this time, the sub CPU 29a displays an opening background image (OP background) for the opening effect. Next, the main CPU 27a outputs a round command for the first round and opens the grand prize winning door 24 for 0.5 seconds (time point X26). When the sub CPU 29a inputs the round command, the sub CPU 29a executes the round effect of the first round based on the round command (time point X26). At this time, the sub CPU 29a displays a one-round background image (1R background) for the first round effect.

  Next, the main CPU 27a outputs a round command for the second round and opens the grand prize winning door 24 for 0.5 seconds (time point X27). When the sub CPU 29a inputs the round command, the sub CPU 29a executes the round effect of the second round based on the round command (time point X27). At this time, the sub CPU 29a displays a 2-round background image (2R background) for the round effect of the second round. Next, the main CPU 27a outputs an ending command (time point X28). When the sub CPU 29a inputs the ending command, the sub CPU 29a executes an ending effect based on the ending command (time point X28). At this time, the sub CPU 29a displays an ending background image (ED background) for the ending effect.

  Then, when the ending effect starts and a predetermined time (4 seconds) elapses, that is, 1 second before the end of the ending effect, the general CPU 28a determines the background switching designation command determined in the background setting process (from the premise) in the output process. Is output. Therefore, the sub CPU 29a controls the display content of the variable display H2 so that the ending background image is changed to the background image B designated by the background switching designation command and displayed (time point X29). That is, the sub CPU 29a changes and displays the ending background image as the background image B during the ending effect.

As described above in detail, this embodiment has the same effects as the effects (1) to (4), (6), and (7) of the first embodiment, and in addition, the following effects.
(11) The sub CPU 29a notifies the small hit game or the big hit 2R big hit game after the display effect related to the symbol change game based on the small hit effect changing pattern P5 or the big hit 2R effect changing pattern P5 is completed. Special game production (opening production, round production, ending production) is performed. For this reason, when the special game effect is performed, the player recognizes that the symbol variation game is a big hit or a small hit, and expects that a probable change state is given. Therefore, during execution of the special game effect, it is possible to make the player pay attention to whether or not the background image to be changed and displayed is a background image that is highly likely to be selected as the background image to be changed in the probability variation state. .

  (12) Also, the sub CPU 29a determines whether any of the background images A to D before the small hit game or the big hit 2R big hit game based on the small hit effect change pattern P5 or the big hit 2R effect change pattern P5. Display a different black background image. For this reason, the player can recognize that the out-of-order symbol combination is temporarily stopped, but can recognize that the symbol combination game is a big hit 2R or a small hit, and can pay attention to the variable display H2. For this reason, the interest of the game is improved.

  (13) Further, when executed in combination with the first embodiment, when the symbol variation game is performed based on the variation pattern P5 for the outlier reach effect, the background image is displayed when the outlier symbol combination is temporarily displayed. Switched and displayed. On the other hand, in the present embodiment, when the symbol variation game is played based on the variation pattern P5 for the small hit effect or the variation pattern P5 for the big hit 2R effect, the background image is displayed when the off symbol combination is temporarily displayed. A black background image different from any of A to D is displayed. Then, since any display effect is performed on the variable display H2 based on the variation pattern P5, the player becomes out of reach of the symbol combination game from the effect contents until the outlier symbol combination is temporarily displayed. It is difficult to guess whether it is a big hit 2R or a small hit. In addition, the variation pattern P5 for the outlier reach effect has a higher probability of being determined than the variation pattern P5 for the small hit effect or the variation pattern P5 for the big hit 2R effect. For this reason, the player can be surprised by displaying the black background image when the out-of-order symbol combination is temporarily displayed. Further, it is possible to make the player notice when the out-of-order symbol combination is temporarily stopped and displayed, and it is possible to improve the interest of the game.

In addition, the said embodiment can be embodied in another embodiment (another example) as follows.
○ The first embodiment may be executed in combination with the second embodiment. In this case, in the output process, the overall CPU 28a outputs a background switching designation command one second before the end of the decoration drawing variation time based on the variation pattern.

  The first embodiment and the third embodiment may be combined and executed. In this case, in the output process, if the special symbol as the final stop symbol is out of the design, the general CPU 28a outputs a background switching designation command 1 second before the end of the decorative drawing change time, and the final stop When the special symbol as the symbol is the big hit symbol [2] or the small bonus symbol [3], the background switching designation command is output one second before the end of the ending effect.

  The first embodiment may be executed in combination with the second embodiment and the third embodiment. In this case, when the variation pattern P9 is designated, the overall CPU 28a outputs a background switching designation command one second before the decoration variation time ends in the output process. In addition, when the variation pattern P5 is designated and the special symbol as the final stop symbol is out of the design, the general CPU 28a switches the background one second before the end of the variation time of the decoration diagram in the output process. Outputs the specified command. Further, the general CPU 28a ends the ending effect when the variation pattern P5 is designated and the special symbol as the final stop symbol is the jackpot symbol [2] or the jackpot symbol [3]. A background switch designation command is output one second before.

  In the first embodiment, the overall CPU 28a changes and displays the background image when the variation pattern P9 for the outlier reach effect is designated, but when the predetermined variation pattern is designated, The background image may be changed and displayed. For example, the overall CPU 28a may change and display the background image when a predetermined deviation pattern for change effect is designated. Further, the general CPU 28a may change and display the background image when a predetermined big hit 15R effect variation pattern is designated. In this case, on the variable display H2, the background image is changed and displayed until the combination of symbols is temporarily stopped and finally stopped, or immediately before the end of the ending effect.

  In the third embodiment, the sub CPU 29a displays the black background image when the variable display H2 is temporarily stopped on the variable display H2 based on the variation pattern P5. You don't have to. In this case, the background image at the start of the symbol variation game is displayed.

As another example, the sub CPU 29a may determine the switching timing of the background image based on the variation pattern (in the first and third embodiments, the variation pattern and the special figure as the final stop symbol).

  In the above embodiment, the overall CPU 28a outputs the current background designation command at the start of the symbol variation game, and the storage content of the background image to be displayed on the variable display H2 in the RAM 28c of the overall control board 28 and the display control board 29 The stored contents of the background image displayed on the variable display H2 in the RAM 29c are corrected. As another example, the overall CPU 28a does not need to output the current background designation command at the start of the symbol variation game to correct the stored content.

  In the third embodiment, the background image is changed and displayed during the ending effect, but the background image may be changed and displayed during the special game (between the opening effect and the ending effect). In this case, it is necessary to continue displaying the changed background image at least until the end of the ending effect.

  In the first embodiment, the symbol variation game may be a big hit 2R or small hit, but the symbol variable game may not be a big hit 2R or small hit.

In the above embodiment, the special figure display H1 and the variable display H2 are provided separately, but they may be configured integrally. In this case, the special figure is displayed at an inconspicuous position on the display screen.
In the above embodiment, there are four types of background images, but any number of background images may be changed as long as there are three or more types. For example, there may be three types of background images or five types of background images.

  In the above embodiment, the overall CPU 28a may output a background switching designation command to the lamp control board 30 to execute a light emission effect with the effect content corresponding to the background image. Similarly, a background switching designation command may be output to the sound control board 31 to execute a sound effect with effect contents corresponding to the background image. At that time, the overall CPU 28a may output the current background designation command for each symbol variation game and correct the background image designated between the control boards 29-31. In this way, the difference in effect content between the control boards 29 to 31 is reduced.
