Description

  The present invention relates to a gaming machine that displays a symbol variation game performed by varying symbols on a game display means, and provides a winning game after a winning display result is derived in the symbol varying game.

  Conventionally, in a pachinko gaming machine which is a kind of gaming machine, a symbol variation game is displayed based on the determination result of the big hit determination, and a big hit that opens the big winning opening when the big hit display result is derived in this symbol variation game Giving a game is done. Then, for the purpose of improving the interest of the player in such a symbol variation game, the variation content of the symbol variation game based on this entry detection is preliminarily determined at the time of entry detection to the specific entrance (start winning entrance). At the same time, there is one that executes a hold change effect that changes a hold image indicating a symbol changing game that is on hold based on the change content that has been determined in advance (for example, Patent Document 1).

  In the pachinko gaming machine of Patent Document 1, a big hit expectation in the symbol variation game corresponding to the reserved image is added by adding a character image (such as a hat or a crown) selected based on the variation content determined in advance to the reserved image. The degree is reported. For this reason, the pachinko gaming machine of Patent Document 1 has a sense of expectation that it will be a big hit in the symbol variation game that is the subject of the on-hold change effect, improving its interest.

  However, when it is recognized that there is a high possibility that the player will win a big hit by executing a game effect based on the variation content of the symbol variation game determined in advance, such as the hold variation effect as in Patent Document 1, Some games stop launching game balls until the end of the symbol variation game to be played. In such a case, there is a possibility that the operating rate of the gaming machine will be lowered and the profit of the gaming store may be pressed. In addition, in the conventional pachinko gaming machine, if the game effect based on the above-described pre-determination is not triggered by the detection of the incoming ball, the player loses interest in the symbol variation game corresponding to the incoming ball detection. It was hard to say that the interests of the people were sufficiently improved.

  The present invention has been made paying attention to the problems existing in the above-described conventional technology, and its purpose is to prevent the player from stopping the launch of the game ball and to the specific entrance. An object of the present invention is to provide a gaming machine that can suppress a decrease in the interest of a player even when a special effect is not started due to the entry of a ball.

In order to solve the above-mentioned problem, the invention according to claim 1 displays a symbol change game performed by changing a symbol on the game display means, and after a win display result is derived in this symbol change game, In a gaming machine that provides a game ball, a plurality of entrances including a start port that can give a start condition of the symbol variation game by entering a game ball, and an entrance detection that detects a game ball that has entered the start port And a random number value including a random number value used for a lottery to determine whether or not the game ball that has entered the start port has been detected by the ball detection means, and Sequentially, the random number acquisition means to be stored in a predetermined storage means, and whether the acquired random number value coincides with the hit determination value when the random number acquisition means acquires the random number value Determine in advance Pre-determination means and special effect control means for controlling the effect execution means based on the determination result of the prior determination means and executing the special effect, wherein the special effect control means is determined by the prior determination means. The entrance detection means for detecting at least a game ball that has entered the start port during a period from when the result becomes affirmative until the symbol variation game based on the random number value affirmatively determined by the prior determination means is started. A control for starting the special effect when a new game ball is detected as a result of the game, and a symbol variation game based on a random number that is determined in advance by the prior determination means when the special effect is being executed. a control to perform a specific notification effect of notifying is possible to structure, the presentation execution section, corresponding to the random number value stored displays suspension information in the storage means, said view pending The hold information display means for informing the number of times of the variable game, and the special effect is a display form of the hold information in the hold information display means from a normal display form that is a display form when entering the start opening. The change to the special display mode is performed, and the change to the special display mode is performed when the special effect is started when the game ball is newly detected by the entrance detection unit. The gist is that it is performed on all the hold information displayed on the screen.

  According to the present invention, the player's interest is reduced even when the special effect is not started when the player enters the specific entrance, while suppressing the player from stopping the game ball. This can be suppressed.

  As shown in FIG. 1, a game display unit having a liquid crystal display type image display unit GH and an effect display device 11 as an effect execution unit are disposed at substantially the center of the game board 10 of the pachinko gaming machine. The effect display device 11 includes a symbol variation game that is performed by varying a plurality of symbol sequences (three columns in this embodiment), and various display effects executed in association with the game are displayed as images. In the present embodiment, in the symbol variation game of the effect display device 11, a symbol combination including a plurality of columns (three columns in the present embodiment) is derived. Note that the symbol variation game of the effect display device 11 is performed using decorative symbols for diversifying display effects.

  In addition, a special symbol display device (hereinafter referred to as “special drawing display device”) 12 made of, for example, a 7-segment LED is disposed at the lower left of the effect display device 11. In the special symbol display device 12, a symbol variation game is displayed in which special symbols are varied and displayed. The special symbol is a symbol for notification indicating a result of an internal lottery (hit lottery lottery described later) as to whether or not to win. Hereinafter, unless otherwise specified, the symbol variation game based on the decorative symbol on the effect display device 11 is referred to as “decorative symbol variation game”, and the symbol variation game based on the special symbol on the special symbol display device 12 is referred to as “special symbol variation game”. In the case where the special figure variation game and the decorative drawing variation game are not distinguished from each other, they are simply denoted as “design variation game”.

  In the present embodiment, when the special symbol variation game is started in the special symbol display device 12 due to the start of the variation of the special symbol, in the effect display device 11, the variation of the decorative symbol is started at the same time, and the decorative symbol variation game is started. The Similarly, in the present embodiment, when the special figure change game is terminated by the special symbol confirmation stop display in the special figure display device 12, the decoration display of the decoration symbol is simultaneously displayed on the effect display device 11, and the decorative figure is displayed. The floating game is ended. As described above, the symbol variation game of the present embodiment is executed once from the variation start of the symbols (special symbol and decorative symbol) until the fixed stop display. In the present specification, “simultaneous” includes not only strictly the same time but also a range that the player can visually recognize at the same time.

  And the display result according to the display result of the special figure display apparatus 12 is displayed on the effect display apparatus 11. FIG. Specifically, when the big hit symbol as the hit display result is confirmed and stopped on the special symbol display device 12, the big hit symbol as the hit display result is also confirmed and stopped on the effect display device 11. When the special symbol display device 12 displays the off symbol as a deviation display result, the off symbol as the off symbol display result is confirmed and stopped.

  The jackpot symbol that is confirmed and stopped displayed on the effect display device 11 is composed of symbol combinations in which the decorative symbols in all the rows are the same symbol (for example, “222”, “777”, etc.). In addition, the off-line symbols that are confirmed and displayed on the effect display device 11 are a combination of symbols in which the decorative symbols in all the rows are different, or a decorative symbol in which the decorative symbols in one row are different from the decorative symbols in the other two rows. It is comprised by the following symbol combination. Further, in the effect display device 11, the variation of the symbol sequence stops in the order of left column → right column → middle column as viewed from the player side, and two specific columns (two columns on the left and right in this embodiment). ), The reach (reach state) is formed (displayed).

  Here, the temporary stop display is a state in which the image display unit GH is displayed in a fluctuation state, and is distinguished from a fixed stop display in which the symbol is fixed and stopped in the image display unit GH. In this embodiment, among the multiple symbol columns, the left column is the first stop column, the right column is the second stop column, the middle column is the third stop column (final stop column), and the left column and the right column are reach. This is the reach formation row to be formed. Also, in the effect display device 11, one of the above-mentioned display effects is produced after the reach is formed (displayed) in the decorative drawing variation game until the symbol combination (big hit symbol or off symbol) is finally derived. Reach production will be performed.

  Further, as shown in FIG. 1, on the left side of the special symbol display device 12, a special symbol hold display device (for example, LEDs) having a plurality (four in this embodiment) of special symbol hold light emitting units (for example, LEDs) is provided. (Hereinafter referred to as “special drawing hold display device”) 13 is provided. The special figure hold display device 13 lights the number of special symbol hold light emitting units as many as the number of the special design start balls stored for the special symbol stored in the machine (hereinafter referred to as “holding memory number”). To the player. The number of reserved memories is incremented by 1 when a game ball enters a later-described starting prize opening provided on the game board 10, while it is decremented by 1 when the symbol variation game is started. Therefore, when a game ball enters the start winning opening during the symbol variation game, the reserved memory number is further added and accumulated up to a predetermined upper limit number (4 in the present embodiment). The number of reserved memories is the number of symbol variation games that are pending execution.

  Further, in the pachinko gaming machine according to the present embodiment, the above-described reserved memory number is also notified on the effect display device 11. As shown in FIG. 2, the image display unit GH of the effect display device 11 has a hold image G with hold information corresponding to each start hold ball (pending symbol variation game) stored inside the machine. On-hold display areas R1 to R4 for displaying are set. Therefore, in the present embodiment, the effect display device 11 functions as a hold information display unit.

  The hold display area R1 corresponds to a symbol change game that is executed first (first) among the symbol change games that are on hold, and the hold display area R2 corresponds to a symbol change game that is executed second. The hold display area R3 corresponds to the third symbol change game executed among the pending symbol change games, and the hold display area R4 is executed last (fourth) of the hold symbol change games. This corresponds to the symbol variation game to be played. The effect display device 11 displays the number of reserved images G equal to the number of reserved memories stored inside the machine, thereby informing the player of the number of reserved memories. For example, when the hold image G is displayed in the hold display areas R1 to R3, it can be recognized that the hold storage number is “3”.

  Further, as shown in FIG. 1, below the special symbol display device 12, a normal symbol display device 14 configured by covering a plurality of (in this embodiment, two) light emitters (for example, LEDs) with a lens cover. Is arranged. In the normal symbol display device 14, a normal symbol variation game is performed in which a plurality of types of normal symbols are changed to derive one normal symbol. The normal symbol display device 14 displays a lottery result of an internal lottery (lottery per later drawing) to determine whether or not to hit a general symbol separately from the big hit lottery to determine whether or not to win. That is, when the lottery per common symbol is won, the normal symbol winning symbol (in this embodiment, the left illuminator is lit) is displayed in a fixed stop state in the normal symbol variation game. On the other hand, if the lottery per regular drawing is not won (in the case of a loss), the symbol of the normal symbol (in the present embodiment, the right side illuminator is lit) is confirmed and displayed.

  Below the effect display device 11, a first start winning port 17 having a game ball entrance 17a is disposed. In the first start winning opening 17 of the present embodiment, a game ball can always enter. Also, below the first start winning opening 17, a second starting winning opening 18 having a game ball entrance 18a is disposed. The second start winning opening 18 is an ordinary electric accessory, and includes an opening / closing blade 19 that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown). The opening of the second start winning opening 18 is expanded by opening the opening / closing blade 19 so that a game ball can easily enter (win), while the opening is not expanded by closing the opening / closing blade 19. In the closed state, it is difficult for the game ball to enter (win).

  A first start switch SW1 (shown in FIG. 4) as a ball detection means for detecting a game ball that has entered the ball is disposed at the back of the first start winning port 17, and the second start winning port. A second start port switch SW2 (shown in FIG. 4) is disposed in the back of the mouth 18 as a ball detection means for detecting a game ball that has entered the ball. Each start winning port 17, 18 detects the entered game ball with each start port switch SW 1, SW 2, thereby paying out a game ball as a predetermined number of winning balls. Conditions can be granted. In the present embodiment, the first start winning port 17 and the second start winning port 18 constitute a ball entrance and a specific ball entrance (start port).

  Also, below the effect display device 11, a special prize opening (special electric accessory) 21 having a special prize opening door 20 that opens and closes by the operation of an actuator (solenoid, motor, etc.) not shown is arranged. Yes. A count switch SW3 (shown in FIG. 4) for detecting a game ball that has entered the ball is disposed in the back of the special winning opening 21. The special winning opening 21 can give a payout condition of game balls as a predetermined number (for example, 10) of winning balls by detecting the gaming balls that have entered. The big winning opening 21 is opened by the opening operation of the big winning opening door 20 during the big winning game as the winning game, and the game ball is allowed to enter. For this reason, during the big hit game, the player can obtain a chance to win a prize ball. Details of the big hit game will be described later.

  Also, a normal symbol operation gate (hereinafter referred to as “gate”) 22 is disposed on the left side of the effect display device 11. Behind the gate 22, a gate switch SW4 (shown in FIG. 4) for detecting a game ball that has entered and passed is provided. The gate 22 can give only the starting condition of the normal symbol variation game (lottery opportunity for lottery per ordinary figure) when the game ball passes.

  In addition, the pachinko gaming machine of this embodiment can be given a probability variation (hereinafter referred to as “probability variation”) state in which the winning probability (lottery probability) of the big hit lottery varies (improves) from a low probability to a high probability after the big hit game ends. It is configured. In this embodiment, the probability variation state is given until the next jackpot game is generated. The probability variation state is advantageous to the player because the winning probability of the big hit lottery varies with a high probability and the big hit is likely to occur. In the present embodiment, a jackpot that gives a probability variation state after the big hit game ends becomes a probability variation big hit, and a jackpot that does not give a probability variation state (gives a non-probability changed state) after the big hit game ends becomes a non-probability variable big hit.

  In addition, the pachinko gaming machine according to the present embodiment is configured to be able to give a variable time shortening (hereinafter referred to as “shortening”) state after the big hit game. In the variable state, the variation time of the normal symbol variation game is shortened, and the winning probability (lottery probability) of the lottery based on the passage through the gate 22 is higher than the normal state (low probability, for example, 13/251). It is improved (varied) to a probability (for example, 250/251). Further, in the variable state, the open / close blade 19 of the second start winning opening 18 opens and closes in an operation pattern different from the non-variable state in which the variable state is not given, when winning by lottery per ordinary drawing.

  Specifically, in the non-variable short state, when the open / close blade 19 is won by a lottery per ordinary symbol (when the symbol of a usual symbol is derived in a normal symbol variation game), a first predetermined number of times ( (For example, once), and the open state is maintained until a first opening time (for example, 0.3 seconds) elapses after the opening. On the other hand, in the variable state, the open / close blade 19 is opened by a second number (for example, three times) larger than the first number when the lottery is won by a lottery per ordinary figure, and is opened after the first opening. The open state is maintained until a second opening time (for example, 1.58 seconds) longer than the one opening time elapses. In this way, the variable state can be advantageous for the player because the open / close blade 19 operates favorably for the player and the rate of entering the second start winning opening 18 per unit time is improved. The variable speed state is a state in which the opening time increases with an increase in the opening time per unit time of the opening / closing blade 19 and is a state in which the entrance rate is improved by increasing the opening time. 2 It is also easy to enter the ball as compared to the non-changing state where entering the start winning opening 18 becomes a non-entering easy state.

Next, the jackpot game will be described.
The jackpot game is started after the jackpot symbol is confirmed and stopped in the symbol variation game and the game ends. When the big hit game is started, an opening effect indicating the start of the big hit game is first performed. After the opening effect is completed, the round game in which the special winning opening 21 is opened is performed a plurality of times up to a predetermined number of rounds (15 in this embodiment). One round game is until the grand prize opening 21 is opened and closed once, and during one round game, the big prize opening 21 is opened until a predetermined round end condition is satisfied. Is done. This round end condition is the first condition for a specified number of game balls to win (the maximum number of winnings, 9 in this embodiment), or the first time that a specified round time (round gaming time, 25 seconds in this embodiment) elapses. Two conditions are supposed to be satisfied. In the round game, a round effect is performed. When the prescribed number of round games are completed, an ending effect indicating the end of the big hit game is performed, and the big hit game is ended.

  In the pachinko gaming machine according to the present embodiment, when the big hit lottery is won, one big hit is determined from two types of big hits, and the big hit game corresponding to the determined big hit is given. Yes. Which of the two types of jackpot is awarded depends on the type of jackpot symbol that is internally determined as a special symbol to be displayed on the special symbol display device 12 when the jackpot lottery is won. Will be decided accordingly. In the present embodiment, among all 100 types of special symbol jackpot symbols displayed on the special symbol display device 12, 50 types are classified as special symbols ZA and 50 types are classified as special symbols ZB.

  After the big hit game given when the special symbol ZA is determined, the probable change state and the short change state are given until the next big hit is generated. In addition, after the jackpot game given when the special symbol ZB is determined, the probability variation state is not imparted (the non-probability variation state is imparted), and a predetermined number of times (in this embodiment, 100 times). A variable state is given until the symbol variation game is played, or until the big hit is generated before the number of symbol variation games is completed. In the present embodiment, the first privilege advantageous to the player is configured by the non-probable change state and the variable state, and the second privilege more advantageous than the first privilege is configured by the probability change state and the variable state.

  In addition, as shown in FIG. 3, the pachinko gaming machine according to the present embodiment changes the display mode of the hold image G displayed in the hold display areas R1 to R4 from the normal hold image G1 as the normal display mode to the special display mode. It is configured to be able to execute a hold change effect as a special effect performed by changing to the hold image G2. In the present embodiment, when the special hold image G2 is displayed in the hold display areas R1 to R4 and the hold change effect is started, compared to the case where the hold change effect is not executed, in the symbol variation game on hold The big hit expectation degree which shows the possibility that the big hit symbol is displayed in a fixed stop state, that is, the probability that the symbol variation game will be a big hit, becomes high.

  In the present embodiment, the normal hold image G1 displayed during the non-execution of the hold change effect is an image imitating a “chicken egg”. In the present embodiment, the special reserved image G2 displayed during the execution of the hold change effect is an image imitating a “chick of chicken”. Therefore, in this embodiment, the player can recognize that the hold change effect is being executed from the situation in which the normal hold image G1 displayed in the hold display areas R1 to R4 is changed to the special hold image G2. The specific control content for executing the hold change effect will be described later in detail.

Next, the control configuration of the pachinko gaming machine will be described with reference to FIG.
A main control board 30 for controlling the entire pachinko gaming machine is mounted on the back side of the pachinko gaming machine of the present embodiment. The main control board 30 executes various processes for controlling the entire pachinko gaming machine and outputs various control commands (control commands) according to the process results. An effect control board 31 is mounted on the back side of the machine. The effect control board 31 controls the operation of various effect devices based on the control command output by the main control board 30.

Hereinafter, specific configurations of the main control board 30 and the effect control board 31 will be described.
The main control board 30 has a main control CPU 30a that executes control operations in a predetermined procedure, a main control ROM 30b that stores a control program for the main control CPU 30a, and a main control CPU that can write and read necessary data. A RAM 30c is provided. A main control ROM 30b and a main control RAM 30c are connected to the main control CPU 30a. The main control CPU 30a is connected to various switches SW1 to SW4 so that detection signals output by detecting the game balls can be input. The main control CPU 30a is connected with a special symbol display device 12, a special symbol hold display device 13, and a normal symbol display device.

  In addition, the main control CPU 30a outputs various random numbers such as a big hit determination random number, a reach determination random number, and a special symbol distribution random number (hereinafter, referred to as "special pattern distribution random number") at predetermined intervals. Random number update processing (random number generation processing) to be updated is executed. The big hit determination random number is a random number used in the big hit lottery (big hit determination). The reach determination random number is a random number used in the reach lottery (reach determination) to determine whether or not to form a reach in the case of a big hit lottery in which the big win is not won, that is, in the case of a loss. The random number for special figure distribution is a random number used when determining the big hit symbol of the special symbol when winning in the big hit lottery, and is set to 100 different integer values from 0 to 99. In the pachinko gaming machine of this embodiment, 100 types of special figure distribution random numbers are associated with each of the 100 special symbol jackpot symbols. The main control RAM 30c stores (sets) various pieces of information (random numbers, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine.

  The main control ROM 30b stores a main control program and various determination values (such as a big hit determination value and a reach determination value). The jackpot determination value is a determination value used in the jackpot lottery, and is determined from the numerical values that can be taken by the jackpot determination random number (all 600 integers from 0 to 599). And the big hit judgment value is the judgment value for non-probability change used in the big hit lottery in the non-probable change state (low probability big hit judgment value) and the judgment value for probability change used in the big hit lottery in the probability change state (high probability big hit judgment value) There is. The set number of determination values for probability variation (20 in this embodiment) is set larger than the number of determination values for non-probability variation (two in this embodiment). According to such setting, the probability of winning in the big hit lottery in the non-probable change state is 2/600, while the probability of winning in the big win lottery in the probable change state is 20/600.

  The non-probability change determination values of the present embodiment are set to two values “17, 125”. On the other hand, the determination value for probability variation of the present embodiment is a total of 20 values obtained by adding 18 values such as “37, 83, 185... (Hereinafter omitted)” to the above two values “17, 125”. Is set. The non-probability variation determination value and the probability variation determination value have different total numbers, but some of the setting values (“17, 125” in the present embodiment) are common values. On the other hand, in the determination values for probability variation, the other values (18) excluding the common values (“17, 125”) are non-common values different from the non-probability variation determination values (common values). Therefore, the value of the random number for jackpot determination that matches the common value matches the jackpot determination value in either the probability change state or the non-probability change state, but does not match the common value and matches the non-common value. The value of the jackpot determination random number to be matched matches the jackpot determination value only in the probability variation state, and does not match the jackpot determination value in the non-probability variation state.

  The reach determination value is a determination value used in internal lottery (reach determination) as to whether or not to form a reach when determining a loss, and is a numerical value that can be taken by a random number for reach determination (all 241 from 0 to 240). It is determined from the (integer of the street). In the present embodiment, two values are set as reach determination values, and according to such settings, the probability of affirmative determination in reach determination is 2/241.

  The main control ROM 30b stores a plurality of types of variation patterns. The variation pattern is a pattern that serves as a base for effects (display effects, light-emitting effects, sound effects) from the start of the symbol variation game to the end of the symbol variation game. The time (variation time) can be specified. In the present embodiment, the plurality of types of variation patterns can be classified into a variation pattern for a jackpot effect, a variation pattern for an outlier reach effect, and a variation pattern for an outlier effect.

  The jackpot effect is an effect developed through a reach effect so that the symbol variation game finally causes the jackpot symbol to be confirmed and stopped. The outlier reach effect is an effect developed through the reach effect so that the symbol variation game finally displays the symbols to be confirmed and stopped. The outlier effect is an effect that is unfolded so that the symbol variation game will finally display the symbol to be confirmed and stopped without going through the reach effect. In the special figure display device 12, when the special figure fluctuation game is started, the special symbol fluctuation (fluctuation display) is continued until the fluctuation time elapses without performing the reach effect. In the present embodiment, as shown in FIG. 5, a fluctuation pattern P1 is prepared as a fluctuation pattern for a loss effect, a fluctuation pattern P2 is provided as a fluctuation pattern for a loss reach effect, and a fluctuation pattern P3 is provided as a fluctuation pattern for a jackpot effect. ing.

Next, the effect control board 31 will be described.
As shown in FIG. 4, on the effect control board 31, an effect control CPU 31a that executes control operations in a predetermined procedure, an effect control ROM 31b that stores a control program for the effect control CPU 31a, and writing of necessary data An effect control RAM 31c that can be read is provided. The effect control ROM 31b and the effect control RAM 31c are connected to the effect control CPU 31a. The effect control CPU 31a executes random number update processing (random number generation processing) in which various random number values such as the value of effect distribution random numbers are updated at predetermined intervals. The effect distribution random number is a random number used when determining various effects. Various information (random values, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine is stored (set) in the effect control RAM 31c. The effect control ROM 31b stores various image display data (image data such as symbols, backgrounds, characters, characters, etc.). In addition to the control program, the effect control ROM 31b stores various tables to be referred to when determining various effects.

  Hereinafter, the special symbol input process (hereinafter referred to as “special figure input process”) or the special symbol start process (hereinafter referred to as “special figure start process”) executed by the main control CPU 30a of the main control board 30 based on the main control program. ) Will be described. In the present embodiment, the main control CPU 30a executes various processes such as a special figure input process and a special figure start process every predetermined control cycle (for example, 4 ms). The special figure start process is executed after the special figure input process is completed.

First, the special figure input process will be described with reference to FIG.
First, the main control CPU 30a sets the first start winning port 17 or the second start winning port 18 based on whether a detection signal is input from the first start port switch SW1 or the second start port switch SW2. It is determined whether or not a game ball has entered (step SA1). When the determination result of step SA1 is negative, the main control CPU 30a ends the special figure input process. On the other hand, if the determination result in step SA1 is affirmative, the main control CPU 30a determines whether or not the number of reserved storage stored in the main control RAM 30c is less than the upper limit number 4 (step SA2).

  On the other hand, if the determination result of step SA2 is affirmative (the number of reserved memories is less than 4), the main control CPU 30a increments the number of reserved memories by 1 (1) (step SA3). That is, the main control CPU 30a causes the main control RAM 30c to store the game balls detected by the start winning ports 17 and 18 as start hold balls. The main control CPU 30a that has updated (added 1) the number of reserved memories controls the display content of the special figure hold display device 13 so as to display the number of reserved memories after update (after addition). Further, the main control CPU 30a sets a hold designation command capable of specifying the number of hold memories after update (after addition) in the output buffer. In the present embodiment, five types of hold designation commands, 0th to 4th hold designation commands, each capable of specifying the number of hold memories “0” to “4” are prepared.

  Next, the main control CPU 30a reads and acquires various random number values (random numbers for jackpot determination, reach determination random numbers, and special figure distribution random numbers in the present embodiment) from the main control RAM 30c. The value is set in a predetermined storage area of the main control RAM 30c corresponding to the reserved storage number (step SA4). Specifically, in the main control RAM 30c, four storage areas respectively associated with the reserved storage numbers “1” to “4” are set, and the main control CPU 30a is updated after adding 1 in step SA3. The value of each read random number is stored in a storage area corresponding to the number of stored storages. For example, when the reserved storage number is “4”, the main control CPU 30a stores each random number value in the storage area corresponding to the reserved storage number “4”.

  For this reason, in the present embodiment, the reserved storage number is a random value stored in the main control RAM 30c (a set of a random number for jackpot determination, a random determination value for reach determination, and a random value for special figure distribution). It can be said that the number of That is, in the present embodiment, each random number value (a set of random values) is stored in the main control RAM 30c up to an upper limit number (in this embodiment, “4”) equal to the upper limit number of the reserved storage numbers. ing. In this embodiment, the main control CPU 30a functions as a random number acquisition unit, and the main control RAM 30c functions as a storage unit.

  Subsequently, the main control CPU 30a compares the value of the jackpot determination random number acquired in step SA4 with the common value among the above-described jackpot determination values, and determines in advance whether or not the two values match (step). SA5). That is, in step SA5, the main control CPU 30a determines that the symbol variation game based on the value of the big hit determination random number (starting holding ball) stored in the main control RAM 30c in the special figure input processing in the current control cycle is the big hit determination. Whether or not the game state at the time is a jackpot effect (whether or not it is a big hit start holding ball) is determined in advance.

  If the determination result in step SA5 is affirmative, the main control CPU 30a confirms the number of reserved memories stored in the main control RAM 30c, and sends a prefetch command according to the confirmed number of reserved memories and the determination result in step SA5. It is generated and set in the output buffer (step SA6). More specifically, as shown in FIG. 7, the main control CPU 30a sets [E1H] as the upper byte of the prefetch command and sets a value indicating the confirmed number of pending storages in the lower byte. In the low-order byte of the prefetch command, [01H] is set when the reserved storage number is “1”, [02H] when the reserved memory number is “2”, and [03H] when the reserved memory number is “3”. ] Is set to [04H] when the number of reserved storage is “4”. Note that the number of reserved memories that the main control CPU 30a confirms in the process of step SA6 is the updated number of reserved memories added by 1 in step SA3 of the special figure input process in the current control cycle.

  Therefore, the prefetch command [E1xxH] is a big hit regardless of whether the game state at the time of the big hit determination is a positive change state or not in the symbol change game based on the value of the random number for big hit determination acquired in step SA4 in the current control cycle. This is a control command that can specify the number of reserved memories at the time of pre-determining whether or not it is an effect and whether or not it is a big hit. After that, as shown in FIG. 6, the main control CPU 30a ends the special figure input process.

  On the other hand, if the determination result in step SA5 is negative, the main control CPU 30a compares the reach determination value with the reach determination random number value obtained together with the jackpot determination random number value in step SA4, and the two values match. (Step SA7). That is, in step SA7, the main control CPU 30a determines that the symbol variation game based on the big hit determination random number value (starting holding ball) stored in the main control RAM 30c in the special figure input processing in the current control cycle is the big hit determination. When the game state at the time is an uncertain change state, it is determined whether or not the reach reach effect is made (whether or not the start hold ball of the miss reach).

  When the determination result of step SA7 is affirmative, the main control CPU 30a confirms the number of reserved memories stored in the main control RAM 30c, and issues a prefetch command according to the confirmed number of reserved memories and the determination result of step SA7. It is generated and set in the output buffer (step SA8). More specifically, as shown in FIG. 7, the main control CPU 30a sets [E2H] as the upper byte of the prefetch command, and sets a value indicating the confirmed number of pending storages in the lower byte. Therefore, the look-ahead command [E2xxH], as a general rule, is a reach achievement effect when the symbol variation game based on the value of the jackpot determination random number acquired in step SA4 is in a non-probable variation state at the time of the jackpot determination. And a control command that can specify the number of reserved memories at the time of prior determination as to whether or not it is a big hit. After that, as shown in FIG. 6, the main control CPU 30a ends the special figure input process.

  If the determination result in step SA7 is negative, the main control CPU 30a confirms the number of reserved memories stored in the main control RAM 30c and generates a prefetch command corresponding to the determination result in step SA7, and outputs the output buffer. (Step SA9). More specifically, as shown in FIG. 7, the main control CPU 30a sets “E3H” as the upper byte of the prefetch command and values (01H to 04H) indicating the number of reserved storages confirmed as the lower byte. Therefore, the look-ahead command [E3xxH] is a shift effect in principle when the symbol variation game based on the value of the jackpot determination random number acquired in step SA4 is a non-probable variation state when the gaming state at the time of the jackpot determination is an uncertain change state. And a control command that can specify the number of reserved memories at the time of prior determination of whether or not a big hit (loss of reach). After that, as shown in FIG. 6, the main control CPU 30a ends the special figure input process.

  On the other hand, if the determination result in step SA2 is negative (the number of held memories is not less than “4”), the main control CPU 30a generates and outputs a fifth hold designation command different from the zeroth to fourth hold designation commands. The buffer is set (step SA10). That is, the fifth hold designation command is a control command that indicates that the upper limit number “4” that can store the start hold ball is exceeded and the game ball has entered the start winning opening 17 or 18. In step SA10, the main control CPU 30a does not add 1 to the reserved memory number because the reserved memory number has reached the upper limit number “4”, and obtains various random numbers to obtain the main control RAM 30c. Is not to be remembered. Thereafter, the main control CPU 30a ends the special symbol input process.

  As described above, in the special figure input process, in principle, a pair of pre-read commands and a hold designation command are set in the output buffer in response to one entry detection to the start winning ports 17 and 18. Become. Note that the prefetch command and the hold designation command set in the output buffer are the effect control board 31 (the production control CPU 31a) in the order of the prefetch command → the hold designation command in the command output process executed in the subsequent control cycle. Is output. The fifth hold designation command is not paired with the prefetch command and is output to the effect control board 31 (effect control CPU 31a) as a single control command. Further, the above-described prefetch commands [E2xxH] and [E3xxH] are control commands indicating that there is a possibility of a big hit when the gaming state at the time of the big hit determination is a probable change state.

  As described above, in the present embodiment, the main control CPU 30a determines whether or not a big hit is made based on the random numbers of the big hit determination random number and the reach determination random number, and whether or not a reach is formed in the event of a loss. It functions as a prior determination means for determining in advance the variation content of the variation game. In this embodiment, the big hit determination value (common value) and the reach determination value are the effect determination values.

Next, the special figure start process will be described.
In the special figure starting process, the main control CPU 30a first executes an execution condition determination as to whether or not an execution condition for the symbol variation game is established. Specifically, the main control CPU 30a makes a negative determination in the execution condition determination when the symbol variation game is being executed or when the big hit game is being played. When the determination result of the execution condition determination is negative, the main control CPU 30a ends the special figure start process.

  On the other hand, if the determination result of the execution condition determination is affirmative (not in the symbol variation game and not in the big hit game), the main control CPU 30a has the number of stored storages stored in the main control RAM 30c being 0 (zero) ) Is executed to determine whether the number is greater than. If the determination result of the memory number determination is negative (the number of reserved memories is “0”), the main control CPU 30a ends the special figure start process. On the other hand, if the determination result of the memory number determination is affirmative (the stored memory number is “1” or more), the main control CPU 30a decrements the reserved memory number by −1 (1 subtraction) because there is a symbol variation game being held. To do. Further, the main control CPU 30a that updates (subtracts 1) the number of reserved memories controls the display content of the special figure hold display device 13 so as to display the number of reserved memories after update (after subtraction). Further, the main control CPU 30a generates a hold designation command that can specify the number of hold memories after update (after subtraction), and sets it in the output buffer.

  Then, the main control CPU 30a stores various random numbers (big hit determination random number, reach determination random number, special figure distribution random number) stored in a predetermined storage area of the main control RAM 30c in association with the reserved storage number. Read the value of. More specifically, the main control CPU 30a reads a random number stored in a storage area associated with the stored storage number “1” that is stored earliest. Then, the main control CPU 30a converts each random number value stored in the storage area associated with the reserved storage number “n (n = 2 to 4)” to the reserved storage number “n−1 (1 to 1-3). Update storage processing (so-called shift processing) to be stored in the storage area associated with “)” is executed.

  That is, the main control CPU 30a stores the random number stored in the storage area associated with the reserved storage number “2” in the storage area associated with the reserved storage number “1”. The main control CPU 30a stores the random number stored in the storage area associated with the reserved storage number “3” in the storage area associated with the reserved storage number “2”. The main control CPU 30a stores the random number stored in the storage area associated with the reserved storage number “4” in the storage area associated with the reserved storage number “3”.

  Subsequently, the main control CPU 30a compares the read jackpot determination random number value with the jackpot determination value, and executes a jackpot determination (big hit lottery) as to whether or not both values match. At this time, if the current gaming state is a non-probability change state, the main control CPU 30a performs a big hit determination using the non-probability change determination value. On the other hand, if the current gaming state is a probability change state, the main control CPU 30a Use the jackpot judgment. Note that the main control CPU 30a grasps whether or not the current gaming state is a probability change state based on a control flag (a probability change flag described later) set in the main control RAM 30c. In the present embodiment, the main control CPU 30a functions as a hit determination means.

  When the determination result of the jackpot determination is affirmative, the main control CPU 30a determines a jackpot and executes a jackpot effect process for executing a symbol variation game serving as a jackpot effect. In the big hit effect process, the main control CPU 30a reads the special figure distribution random number value read together with the big hit determination random number value. Then, the main control CPU 30a determines a special symbol (big hit symbol) to be confirmed and stopped on the special symbol display device 12 based on the read special figure distribution random number value, and also displays a variation pattern for the big hit effect. Select and decide.

  On the other hand, when the determination result of the big hit determination is negative, the main control CPU 30a recognizes the deviation from the fact that the value of the big hit determination random number is not a big hit value. For this reason, the main control CPU 30a compares the reach determination value with the value of the reach determination random number read together with the value of the big hit determination random number, and determines whether or not both values match. If the determination result of the reach determination is affirmative, the main control CPU 30a has won the reach in the reach lottery, and therefore executes a reach effect process for executing a symbol variation game that becomes a lost reach effect.

  In the reach effect process, the main control CPU 30a determines a deviated symbol as a special symbol to be confirmed and stopped on the special symbol display device 12, and selects and determines a variation pattern for the deviant reach effect. Thereafter, the main control CPU 30a ends the special figure start process.

  On the other hand, when the determination result of the reach determination is negative, the main control CPU 30a does not win the reach in the reach lottery, and therefore executes the offending effect process for executing the symbol variation game that becomes the outlier effect. In the offending effect process, the main control CPU 30a determines a notifying symbol as a special symbol to be confirmed and stopped on the special figure display device 12, and selects and determines a variation pattern for the offending effect. Thereafter, the main control CPU 30a ends the special figure start process.

  As described above, the main control CPU 30a forms a reach when it is a big hit or not based on the random numbers of the big hit determination random number and the reach determination random number stored in the main control RAM 30c. The variation content of the symbol variation game such as whether or not is determined. Therefore, in the present embodiment, the main control CPU 30a functions as a variation content determination unit.

  Then, the main control CPU 30a that has determined the special symbol and the variation pattern, in a process different from the special figure start process, generates a control command generated according to the determination items of the special figure start process on the effect control board 31 at a predetermined timing. Output. Specifically, the main control CPU 30a first outputs a variation pattern designation command for instructing a variation pattern and instructing the start of the symbol variation game of the effect display device 11 at the start of the symbol variation game.

  Further, the main control CPU 30a outputs the hold designation command next after outputting the variation pattern designation command. Further, the main control CPU 30a outputs a special symbol designating command (hereinafter referred to as a “special symbol designating command”) for designating a special symbol, after outputting the hold designation command. The main control CPU 30a then outputs an all symbol stop command for instructing the end of the symbol variation game (the symbol fixed stop display) when the variation time set in the instructed variation pattern has elapsed. The CPU 30a for main control causes the special symbol display device 12 to start the variation of the special symbol together with the output of the variation pattern designation command, and causes the special symbol to be fixedly stopped and displayed together with the output of the all symbol stop command.

  When the main control CPU 30a determines the big hit, after the end of the symbol variation game based on the determined variation pattern, the main control CPU 30a starts controlling the type of big hit game specified based on the special symbol big hit symbol (final stop symbol) To do.

Further, the main control CPU 30a executes a game state control process when the big hit game is terminated.
In the game state control process, the main control CPU 30a sets “1” to a probability variation flag indicating that a probability variation state is to be given after the jackpot game based on the special symbol ZA is ended, while the jackpot game based on the special symbol ZB. After the end of, “0” is set to the probability variation flag. The probability variation flag is stored in the main control RAM 30c. Further, the main control CPU 30a sets “1” to the operation flag indicating that the variable state is given after the big hit game based on the special symbol ZA or the special symbol ZB. The operation flag is stored in the main control RAM 30c. In addition, the main control CPU 30a stores “100 times” as the number of operation times indicating the number of remaining symbol variation games to which the variable state is given after the end of the big hit game based on the special symbol ZB, in a predetermined storage in the main control RAM 30c. Set to area. The main control CPU 30a subtracts “1” from the number of times of operation every time the symbol variation game is executed, and sets the operation flag to “0” when the value becomes “0”. The main control CPU 30a sets “0” to the probability variation flag, the operation flag, and the number of operations at the start of the big hit game. Thereby, the gaming state during the big hit game is a non-probable variation state and a non-variable short state.

  Next, various processes executed by the effect control CPU 31a of the effect control board 31 based on the effect control program will be described with reference to FIGS. In the present embodiment, the effect control CPU 31a executes various processes such as a command input process described below every predetermined control cycle.

First, command input processing will be described with reference to FIG.
As shown in FIG. 8, the effect control CPU 31a determines whether or not a prefetch command is input from the main control board 30 (main control CPU 30a) (step SB1).

  If the determination result in step SB1 is affirmative, the effect control CPU 31a acquires the effect distribution random number value from the effect control RAM 31c and inputs the acquired effect distribution random number value and the current control cycle. Based on the value of the pre-read command being performed, the effect pattern is determined with reference to the effect distribution table TA shown in FIG. 9 (step SB2). The effect distribution table TA is stored in the effect control ROM 31b.

  As shown in FIG. 9, in the effect distribution table TA, effect patterns YP0 and YP1 are associated with each prefetch command. The effect pattern YP0 specifies that the hold change effect is not executed (no hold change effect), and the effect pattern YP1 can execute the hold change effect (allow the execution of the hold change effect). Has been identified. Therefore, when the production control CPU 31a determines the production pattern YP0, the production control CPU 31a decides (determines) the hold change production as unexecutable (executable), whereas when the production pattern YP1 is decided, the production change YP1 holds. Is determined (determined) to be executable (executable). That is, in step SB2, the effect control CPU 31a determines whether one of the effect patterns YP0 and YP1 can execute the hold change effect (executable) or cannot execute the hold change effect (not executable). Is determined (determined).

  Then, in the effect distribution table TA, the value of the random number for effect distribution is assigned to each effect pattern YP0, YP1 for each pre-read command, and the values that can be taken by this random number (0 to 99 total 100 kinds of adjustments). A predetermined number is assigned from among (numerical values). According to the effect distribution table TA, for example, when the prefetch command [E1xxH] is specified, the effect pattern YP0 can be determined with a probability of 40/100 and the effect pattern YP1 can be determined with a probability of 60/100. .

  According to the distribution mode of the random number value for the effect distribution in the effect distribution table TA, the ratio determined when the big hit effect is specified by the pre-read command in the order of the effect pattern YP0 <YP1, and the outlier effect or the outage The ratio determined when the jackpot effect occupying the combined ratio of the ratios determined when the reach effect is specified becomes high. Therefore, in this embodiment, when the hold image G is changed from the normal hold image G1 to the special hold image G2, the expectation degree of big hit is higher when the hold change effect is executed.

  According to the performance distribution table TA, in the order of the performance pattern YP0 <YP1, the ratio determined when the change contents including the reach effect (big hit effect and the outlier reach effect) are specified by the look-ahead command and the reach effect are included. The proportion determined when the variation content including the reach effect in the total proportion of the proportion determined when no variation content is specified is increased. Therefore, in this embodiment, the possibility that the reach effect is performed in the symbol variation game that is on hold is higher when the hold change effect is executed.

  As shown in FIG. 8, when the effect control CPU 31a determines the effect pattern, the effect flag F1 as information indicating whether or not the hold change effect can be executed corresponds to the reserved memory number specified by the prefetch command. To be stored in the storage area of the effect control RAM 31c (step SB3).

  More specifically, in the effect control RAM 31c, four storage areas respectively associated with the number of reserved memories “1” to “4” are set, and the effect control CPU 31a is the lower byte of the prefetch command. The effect flag F1 is stored in the storage area corresponding to the designated reserved storage number. For example, when the prefetch command [E103H] is input, the effect flag F1 is stored in the storage area associated with the reserved storage number “3”. The effect control CPU 31a sets “00H” as the effect flag F1 when the effect pattern YP0 is determined, and “01H” as the effect flag F1 when the effect pattern YP1 is determined. Therefore, when the value of the effect flag F1 is “00H”, the hold change effect cannot be executed (executable), and when the value is “01H”, the hold change effect can be executed (executed). It is information indicating that it is possible.

  Next, the effect control CPU 31a corresponds to the status flag F2 as information indicating the display mode of the reserved image G to be displayed on the effect display device 11, that is, the type of the reserved image G, and the reserved memory number specified by the prefetch command. It is stored in the storage area of the effect control RAM 31c (step SB4). More specifically, the effect control CPU 31a sets “00H” regardless of which of the effect patterns YP0 and YP1 is determined in step SB2. The current flag F2 indicates that the normal hold image G1 is displayed (displayed) as the normal hold image G1 when the value is “00H”, and the special hold image G2 is displayed as the hold image G when the value is “01H”. Information. As described above, the effect control CPU 31a determines whether or not the hold change effect can be executed by the processes of steps SB1 to SB4 of the command input process. Thereafter, the effect control CPU 31a ends the command input process.

  When the determination result in step SB1 is negative (when a prefetch command is not input), the effect control CPU 31a detects that a new game ball has been detected by each start port switch SW1, SW2 (start winning port 17). , 18 is selected as a trigger (step SB5). More specifically, the effect control CPU 31a makes a negative determination in step SB5 when the 0th and 1st hold designation commands are input. In step SB5, when the second and third hold designation commands are input, the presentation control CPU 31a determines that the hold storage number specified by the hold designation command is input by the previous control cycle. Affirmative determination is made when there is an increase from the number of pending storages specified in. In addition, when the fourth and fifth hold designation commands are input, the effect control CPU 31a makes a positive determination in step SB5. In this way, the effect control CPU 31a determines whether or not a game ball has won (or won) a ball in any of the start winning ports 17 and 18 in step SB5.

  When the determination result of step SB5 is negative, the effect control CPU 31a ends the command input process. If the determination result in step SB5 is affirmative, the effect control CPU 31a sets “01H” indicating the reserved storage number “1” in the determination flag F3 stored in the effect control RAM 31c (step SB6). This determination flag F3 is a control flag used for performing the processing of steps SB7 to SB9 described below for each start-pending ball (pending symbol variation game). Note that the determination flag F3 indicates that the reserved storage number is “2” when the value is “02H”, the reserved storage number “3” when the value is “03H”, and the determination flag F3 when the value is “04H”. The reserved storage number “4” is indicated.

  Next, the effect control CPU 31a sets the value of the effect flag F1 stored in the storage area associated with the reserved memory number indicated by the value of the determination flag F3 in the effect control RAM 31c to the same reserved memory number. It is determined whether or not the value of the current flag F2 stored in the associated storage area does not match (step SB7). That is, in step SB7, the effect control CPU 31a sets the display mode of the hold image G displayed on the effect display device 11 in correspondence with the hold storage number indicated by the determination flag F3 to the special hold image G2, and holds the hold. It is determined whether or not the change effect has been started (executed).

  When the determination result of step SB7 is affirmative (when the change change effect has not been started), the effect control CPU 31a sets the display mode of the hold image G as the special hold image G2, for example, by lottery using a predetermined random value. It is determined whether to start (execute) the hold change effect (step SB8). When the determination result in step SB8 is affirmative (when the on-hold change effect is started), the effect control CPU 31a includes the on-hold storage number specified by the on-hold specification command input in the current control cycle, and this on-hold storage. All the current flags F2 stored in the storage area corresponding to the number of reserved storages equal to or less than the number are set to “01H” and updated (step SB9). For example, when the reserved storage number “4” is designated by the hold designation command, the effect control CPU 31a sets all the current flags F2 stored in the storage areas corresponding to the hold memory numbers “1” to “4”. Set “01H”. That is, if the determination result in step SB8 is affirmative (when the hold change effect is started), the hold image G corresponding to all the start hold balls (the value of the big hit determination random number) stored at that time is displayed. The special hold image G2 is changed to start a hold change effect.

  Next, the effect control CPU 31a determines whether or not the value of the determination flag F3 matches the determination end value indicating the number obtained by subtracting 1 from the reserved storage number specified by the hold specifying command (step SB10). When the fifth hold designation command is input, the effect control CPU 31a performs processing assuming that the hold storage number “5” is designated for the convenience of control. The effect control CPU 31a sets “01H” when the number of reserved memories designated by the hold designation command is “2”, “02H” when “3”, and “03H” when “4”. "Is set to" 5 "," 04H "is set as the determination end value.

  When the determination result of step SB10 is affirmative (when the determination end value has been reached), the effect control CPU 31a ends the command input process. On the other hand, when the determination result of step SB10 is negative (when the determination end value is not reached), the effect control CPU 31a adds “01H” to the determination flag F3 (step SB11). Thereafter, the effect control CPU 31a proceeds to the process of step SB7. In addition, when the determination result of step SB7 is negative (when the hold change effect is already started) or when the determination result of step SB8 is negative (when the hold change effect is not started), the effect control CPU 31a performs step SB10. Move on to processing.

  As described above, in the present embodiment, by the process of steps SB6 to SB11 of the command input process, the start holding ball corresponding to the reserved memory number less than the reserved memory number specified by the hold designation command (the pending symbol variation game) ) Only, it is determined whether to change the display mode of the hold image G and start the hold change effect. Therefore, in the command input process of the present embodiment, when it is determined that the hold change effect can be executed with the input of the prefetch command, the hold change effect is triggered with the input of the hold designation command that is paired with the prefetch command. Will not start.

  In the command input process of the present embodiment, when it is determined that the hold change effect can be executed in response to the input of the prefetch command (hold specification command), the input of a new hold specification command, that is, the start winning openings 17, 18 An on-hold change effect can be started when a new ball enters. In particular, in the command input process of the present embodiment, the change of the hold is also triggered by the input of the fifth hold designation command, that is, the starting winning holes 17 and 18 exceeding the upper limit number (four in this embodiment). Production can be started. With this configuration, in this embodiment, even if it is determined that the hold change effect can be executed internally, in order to actually start (execute) the hold change effect, the start winning opening 17 , 18 needs to enter the ball further.

  In this way, in step SB8 of the command input process, the effect control CPU 31a inputs the pre-read command to the start winning holes 17 and 18 between the time when the symbol variation game corresponding to this pre-read command is started. It is determined whether or not to start the hold change effect when a new game ball is won. Therefore, in the present embodiment, the effect control CPU 31a functions as a start determination unit.

  Then, the effect control CPU 31a controls the effect display device 11 to display the hold image G based on the value of the current flag F2 set in the command input process. Details will be described below.

  In the present embodiment, the hold display areas R1 to R4 are respectively associated with the hold storage number (random number value). That is, the hold display area R1 has a hold memory number “1”, the hold display area R2 has a hold memory number “2”, the hold display area R3 has a hold memory number “3”, and the hold display area R4 has a hold memory number “1”. 4 ”.

  When the current state flag F2 is set to “00H” in step SB4 of the command input process, the effect control CPU 31a normally holds the hold in the hold display area corresponding to the hold storage number designated by the hold designation command (prefetch command). The effect display device 11 is controlled so that the image G1 is newly displayed. In addition, when the current flag F2 is set to “01H” in step SB9 of the command input process, the effect control CPU 31a causes the current flag F2 to be displayed in the hold display area corresponding to the number of hold memories associated with the current flag F2. The effect display device 11 is controlled to change the display mode of the reserved image G being displayed to the special reserved image G2. That is, the effect control CPU 31a changes the display mode of the reserved image G from the normal reserved image G1 to the special reserved image G2, and controls the effect display device 11 so that the hold change effect is started (executed).

  As described above, when the CPU 31a for effect control makes an affirmative determination in step SB8 of the command input process, all of the storage areas stored in the storage areas corresponding to the number of reserved memories less than or equal to the number of reserved memories specified by the hold designation command are stored. Update the current flag F2 by setting "01H". Therefore, in this embodiment, all of the hold images G displayed in the hold display areas R1 to R4 are set as the special hold images G2, and the hold change effect is started.

Next, the contents of control performed by the effect control CPU 31a when a variation pattern designation command is input will be described.
When the change pattern designation command is input, the effect control CPU 31a newly associates the effect flag F1 and the current flag F2 in the effect control RAM 31c in association with the reserved memory number obtained by subtracting -1 (1 subtraction) from the current reserved memory number. Update storage processing to be stored is executed. More specifically, in the update storage process, the effect control CPU 31a displays the flags F1 and F2 stored in the storage area corresponding to the reserved storage number “n (n = 2 to 4)” as the reserved storage number. It is stored in the storage area associated with “n−1 (1-3)”.

  According to such a configuration, the flags F1 and F2 corresponding to the random number value (starting holding ball) stored in the main control RAM 30c triggered by the detection of the entering at the start winning ports 17 and 18 are as follows. Until the symbol variation game based on the corresponding random number value (starting holding ball) is started, it is stored and held in the effect control RAM 31c.

  Then, the effect control CPU 31a controls the effect display device 11 so that the hold image G corresponding to the current flag F2 is displayed in the hold display area corresponding to the updated hold memory number updated by the update storage process. Shift display processing is performed. That is, the effect control CPU 31a displays the hold image G displayed in the hold display area corresponding to the hold storage number “n (n = 2 to 4)” by the shift display process. 1 to 3) ”is displayed in the hold display area. It should be noted that the effect control CPU 31a provides an effect display device such that the hold image G is erased for the hold display area corresponding to the hold memory number that exceeds the hold memory number designated by the hold designation command input together with the variation pattern designation command. 11 is controlled.

  More specifically, the CPU 31a for effect control holds the hold image G displayed in the hold display area R4 in the hold display area R3 and holds the hold image G displayed in the hold display area R3 by the shift display process. The effect display device 11 is controlled to be displayed so as to move to the display region R2. Further, the effect control CPU 31a displays the hold image G displayed in the hold display area R2 by the shift display process so as to move to the hold display area R1, and further holds the hold image displayed in the hold display area R1. The effect display device 11 is controlled as if G is erased.

  Therefore, the effect control CPU 31a inputs the pre-read command indicating the result of the pre-determination of the main control CPU 30a until the start of the symbol variation game corresponding to the pre-read command. 18 is configured to enable the control to start the hold change effect when the game ball is newly won. In the present embodiment, the effect control CPU 31a that controls the effect display device 11 based on the prefetch command to start (execute) the hold change effect functions as a special effect control unit.

  In the shift display process, the effect control CPU 31a does not rewrite the value of the current state flag F2 stored in the effect control RAM 31c in association with the reserved storage number. That is, the effect control CPU 31a does not rewrite the current state flag F2 when the symbol variation game starts (input of the variation pattern designation command), and does not start (execute) the hold variation effect when the symbol variation game starts. It has become.

  In addition, when the variation control designation command is input, the effect control CPU 31a starts the variation (variation display) of the decorative symbols in all the columns, and controls the effect display device 11 so that the decoration variation game is started. Further, the effect control CPU 31a selects the image display data based on the variation pattern designated by the variation pattern designation command. The effect control CPU 31a controls the display content of the effect display device 11 so as to display the decoration variation game based on the selected image display data. In addition, the CPU 31a for effect control measures the elapsed time from the start of the decoration variation game, and displays an image displayed on the effect display device 11 based on the measured time and display data for each predetermined control cycle (for example, Every 4 ms).

  In addition, when the special symbol instructed by the special symbol designation command is the special symbol ZA (probability variation jackpot), the effect control CPU 31a determines a symbol combination that can recognize the probability variation jackpot as the symbol combination of the decorative symbol. On the other hand, when the special symbol instructed by the special symbol designation command is the special symbol ZB (non-probable variation big hit), the effect control CPU 31a determines a symbol combination that can recognize the non-probable variation big hit as a symbol combination of the decorative symbols. In addition, when the special symbol instructed by the special symbol designation command is a missing symbol, the effect control CPU 31a determines a symbol combination capable of recognizing the deviation. At this time, when the variation pattern for the outlier reach effect is instructed, the effect control CPU 31a determines a symbol combination that can recognize the outbreak including the reach symbol combination (reach formation symbol). On the other hand, when the variation pattern for the offending effect is instructed, the effect control CPU 31a determines a symbol combination that can recognize a disregard that does not include the reach symbol combination (reach formation symbol).

  Then, when the all-design stop command is input during the decoration variation game, the production control CPU 31a controls the display contents so that the determined display on the effect display device 11 is confirmed and stopped, and ends the decoration variation game. Let

  Next, an example of the execution mode of the hold change effect realized in the pachinko gaming machine of the present embodiment will be described with reference to FIG. In FIG. 10, only the holding display areas R1 to R4 displayed on the image display unit GH of the effect display device 11 are extracted and shown. Further, in FIG. 10, it is determined that the hold change effect can be executed based on the first winning to the start winning ports 17 and 18, while the hold change effect cannot be executed based on the subsequent winnings. The determined situation shall be indicated.

  As shown in FIG. 10A, in the hold display area R1, it is determined that a hold change effect can be executed based on a determination result of a pre-determination triggered by winning at the start winning ports 17 and 18. The normal hold image G1 is displayed. Note that the hold display areas R1 to R4 are normally held even if it is determined that the hold change effect cannot be executed based on the result of the prior determination triggered by the winning at the start winning ports 17 and 18. An image G1 is displayed. Therefore, the player cannot recognize whether or not the hold change effect is determined to be executable internally from the situation where the normal hold image G1 is displayed in the hold display areas R1 to R4.

  As shown in FIG. 10 (b), when it is determined that the hold change effect is started with a new winning at the start winning openings 17, 18, the normal hold image G1 is the special hold image in the hold display area R1. While being changed to G2, a special hold image G2 is displayed in the hold display area R2. As a result, the player changes the holding change effect in response to the fact that the two symbol variation games are put on hold, and winning in the start winning ports 17 and 18 corresponding to the holding image G displayed in the holding display area R1. Can be recognized as being executable. That is, the player can recognize that the jackpot expectation is high in the symbol variation game that is executed first among the two symbol variation games on hold.

  On the other hand, as shown in FIG. 10 (c), when it is determined not to start the hold change effect in response to a new winning at the start winning ports 17 and 18, the normal display image G1 is displayed in the hold display area R1. And the normal hold image G1 is displayed in the hold display area R2.

  As shown in FIG. 10 (d), when it is determined that the hold change effect is to be started in response to a new winning at the start winning openings 17 and 18, the normal hold image G1 is special in the hold display areas R1 and R2. While being changed to the hold image G2, the special hold image G2 is displayed in the hold display area R3. As a result, the player can enter the start winning openings 17 and 18 corresponding to at least one of the hold images G displayed in the hold display areas R1 and R2 and that the three symbol variation games are held. It can be recognized that it has been determined that the pending change effect can be executed in response to the winning. That is, the player can recognize that the jackpot expectation is high in at least one of the symbol variation games of the first and second symbol variation games among the three symbol variation games on hold.

  On the other hand, as shown in FIG. 10 (e), when it is determined not to start the hold change effect triggered by a new winning at the start winning openings 17 and 18, in the hold display areas R1 and R2, the normal hold image G1 is displayed. Is maintained, and the normal hold image G1 is displayed in the hold display area R3.

  As shown in FIG. 10 (f), when it is determined that the hold change effect is to be started in response to a new winning at the start winning ports 17 and 18, the normal hold image G1 is special in the hold display areas R1 to R3. While being changed to the hold image G2, the special hold image G2 is displayed in the hold display area R4. As a result, the player can see that the four symbol variation games have been put on hold, and the start winning openings 17 and 18 corresponding to at least one of the hold images G displayed in the hold display areas R1 to R3. It can be recognized that it has been determined that the pending change effect can be executed in response to the winning. That is, the player can recognize that the jackpot expectation is high in at least one symbol variation game among the first to third symbol variation games among the three symbol variation games on hold.

  On the other hand, as shown in FIG. 10 (g), if it is determined not to start the hold change effect triggered by a new winning at the start winning openings 17 and 18, the normal hold image G1 is displayed in the hold display areas R1 to R3. Is maintained, and the normal hold image G1 is displayed in the hold display area R4.

  Then, as shown in FIG. 10 (h), when it is determined that the hold change effect is to be started in response to a new winning at the start winning openings 17, 18, the normal hold image G1 is displayed in the hold display areas R1 to R4. Is changed to a special reserved image G2. Thus, the player can recognize that the four symbol variation games are held, that is, the number of the symbol variation games being held has not increased. In addition, the player has been determined to be able to execute a hold change effect triggered by winning a winning winning opening 17 or 18 corresponding to at least one of the hold images G displayed in the hold display areas R1 to R4. You can recognize that. That is, the player can recognize that the big hit expectation is high in at least one symbol variation game among the first to fourth symbol variation games among the four symbol variation games on hold.

  Thus, in this embodiment, even if it is determined that the hold change effect can be executed internally, if the new winning is not made to the start winning opening 17, 18, the hold change effect is displayed. Not started. In addition, the present embodiment is configured such that the on-hold change effect can be started even when a winning is received at the starting winning ports 17 and 18 exceeding the upper limit number that can store the starting holding ball (random number value). Therefore, in the pachinko gaming machine of this embodiment, regardless of whether or not the number of reserved memory has reached the upper limit number, the willingness to continue launching the game ball to the player who has a sense of expectation for the start of the change effect on hold Can be given.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) When the main control CPU 30a determines in advance that it is a big hit, the hold change effect can be started when a new game ball is detected by each of the start port switches SW1, SW2 (start winning ports 17, 18). . In other words, even when the winning change effect is not started with respect to the hold image G displayed corresponding to the winning along with the winning (winning) to the starting winning openings 17 and 18, the starting winning opening is further increased. There is a possibility that the holding change effect is started by winning (entering) the game balls at 17 and 18. Therefore, even if the player does not stop launching the game ball and the on-hold change effect is not started in response to winning at the start winning opening 17 or 18, the player's interest is reduced. Can be suppressed.

  (2) The display mode of the hold image G displayed on the effect display device 11 is changed from the normal hold image G1 to the special hold image G2, and the hold change effect is started. The hold image G displayed on the effect display device 11 is a place where the player's attention is easily collected, and the player's interest can be improved suitably by starting the hold change effect.

  (3) In step SB8 of the command input process, the effect control CPU 31a determines whether or not to start the hold change effect in response to a new winning at the start winning ports 17 and 18, and the determination result The on-hold change effect is started on the condition that becomes affirmative. For this reason, it is possible to create a situation in which the hold change effect is started and a situation in which the hold change effect is not started when the game ball enters the start winning ports 17 and 18. Therefore, the player's interest is reduced even when the special presentation is not started when the player enters the start winning holes 17 and 18 while suppressing the player from stopping the game ball. Can be suppressed.

  (4) The effect control CPU 31a determines whether or not the number of reserved memories has reached the upper limit number, that is, whether or not the number of random numbers stored in the main control RAM 30c has reached the upper limit number. On the occasion of winning the game balls at 17 and 18, the hold change effect is started. For this reason, even if the number of reserved memories reaches the upper limit number, the hold change effect can be started when a new winning is made in the start winning ports 17 and 18. Therefore, even when the number of reserved memories reaches the upper limit, it is possible to suppress the player from stopping the launch of the game ball.

  (5) When the determination result in step SB8 of the command input process is affirmative (when the hold change effect is started), the effect control CPU 31a starts the hold change effect with all the hold images G as the special hold images G2. Therefore, when the number of symbol variation games held before that is two or more, it can be recognized that the symbol variation game with high expectation degree is included in the pending symbol variation game Therefore, it cannot be specified which of the reserved images G has a high expectation degree for the symbol variation game. Therefore, in the present embodiment, not only the reserved image G corresponding to the winning determined to be able to actually execute the hold change effect, but also each symbol variation game corresponding to the reserved image G set as the special reserved image G2. , Can make the player have a sense of expectation.

  (6) In the present embodiment, even when it is determined that the hold change effect can be executed in response to winning at the start winning ports 17 and 18, the normal holding image G1 is always used as the holding image G corresponding to this winning. Is displayed, and the hold change effect is not started simultaneously with the winning. For this reason, in the present embodiment, it is possible to give the player who expects that the on-hold change effect is started to have a willingness to further win the start winning ports 17 and 18.

  (7) Even when a game ball enters the start winning opening 17 or 18 exceeding the upper limit number “4” of the stored storage number, a fifth hold designation command is output to the effect control board 31, A hold change effect can be started. Therefore, it is possible to reliably give the opportunity to start the hold change effect to the effect control CPU 31a.

(8) The hold change effect is not started with the start of the symbol variation game. For this reason, it is possible to make the player have a greater willingness to launch a game ball.
In addition, you may change the said embodiment as follows.

  When starting the hold change effect, the effect control CPU 31a starts the hold change effect (changes to the special hold image G2) before changing the hold image G to the special hold image G2 and displaying it. May be displayed (executed) on the effect display device 11.

  -When performing the hold change effect, the effect control CPU 31a is specified as a special effect for notifying the player of the hold image G corresponding to the start hold ball (random value) determined to be able to execute the hold change effect. The notification effect may be displayed (executed) on the effect display device 11 as the special effect executing means. According to this, when the hold image G corresponding to the start hold ball (random value) determined to be able to execute the hold change effect is informed, which of the hold images G can be expected to have the symbol variation game Can be recognized by the player and its interest can be improved. In this case, the effect control CPU 31a sets the effect mode from the start until the predetermined time elapses to the same mode as the specific notification effect, and finally decides that the hold change effect can be executed. It is also possible to execute the specific notification effect of the gusset that does not notify the player of the hold image G corresponding to.

  The effect control CPU 31a may change only the hold image G corresponding to the start hold ball (random value) determined to be able to execute the hold change effect to the special hold image G2, and start (execute) the hold change effect. Good. In addition to this, after the reserved image G displayed on the hold display areas R1 to R4 is changed to the special hold image G2, the effect control CPU 31a further changes the display mode of the hold image G in a plurality of stages. The hold change effect may be displayed so that the expectation degree of jackpot is higher as the display mode is closer to the final stage.

  In this case, the effect distribution table TA is associated with a plurality of types of effect patterns with different upper limit stages for changing the display mode of the reserved image G so as to be selectable. Then, the effect control CPU 31a has a ratio determined when the big hit effect is specified by the pre-read command and the outlier effect or the outlier reach effect as the upper limit stage for changing the display mode is an effect pattern closer to the final stage. The effect pattern is selected so that the ratio determined when the jackpot effect occupying the combined ratio of the ratios determined when specified is high. In addition, when an affirmative determination is made in step SB5 of the command input process, the effect control CPU 31a displays the hold image G when the pre-read command is input for each start hold ball less than the hold storage number specified by the hold designation command. On the condition that the upper limit stage specified by the determined production pattern has not been reached, a change permission determination is made as to whether or not to change to the display mode of the next stage. Then, the effect control CPU 31a controls the effect display device 11 to change the display mode of the reserved image G on the condition that the determination result of the changeability determination is affirmative.

  According to such a configuration, when the on-hold change effect is started, by winning the start winning ports 17 and 18, toward the final stage where the display mode of the on-hold image G becomes a higher jackpot expectation degree. Can change. For this reason, it is possible to have a willingness to continuously launch the game ball even after the hold change effect is started. Therefore, it is possible to improve the interest in the hold change effect while suppressing the player from stopping the launch of the game ball. Moreover, according to this example, the hold image G can be changed up to a stage according to whether or not the jackpot effect is achieved (preliminarily determined variation content of the symbol variation game). Therefore, the number of stages at which the reserved image G is changed can be associated with the variation content of the symbol variation game, and the interest in special effects can be further improved.

  Further, when the determination result in step SA5 of the special figure input process is affirmative (when it is determined in advance that it is a big hit), the main control CPU 30a determines the special symbol based on the value of the special figure distribution random number acquired in step SA4. The big hit symbol may be determined in advance, and a special figure prefetch command for specifying the type of the big hit symbol of the special symbol determined in advance may be output to the effect control CPU 31a. In this case, the special figure prefetch command is paired with the prefetch command and the hold designation command and is output to the effect control CPU 31a. In this case, in the effect distribution table TA, a plurality of types of effects with different upper limit stages for changing the display mode of the reserved image G are selected as effect patterns that can be selected only when a prefetch command for specifying the jackpot effect is input. Corresponding patterns can be selected.

  Then, the effect control CPU 31a has a ratio determined when the special symbol ZA (probability big hit) is specified by the special figure prefetch command, as the upper limit stage for changing the display mode is an effect pattern closer to the final stage, The effect pattern is selected such that the ratio determined when the special symbol ZA occupying the total proportion of the ratio determined when the special symbol ZB (non-probable big hit) is specified is high. According to such a configuration, the hold change effect is started, and the closer the display mode of the hold image G is to the final stage, the higher the possibility that the profit will be a probable big hit as a bonus (privilege expectation expectation). Therefore, it is possible to improve the interest in the hold change effect while suppressing the player from stopping the launch of the game ball. In addition, according to this example, the reserved image G can be changed to a stage according to the special symbol jackpot symbol (the variation content of the symbol variation game determined in advance) in the case of the jackpot effect. Therefore, the number of stages at which the reserved image G is changed can be associated with the variation content of the symbol variation game, and the interest in special effects can be further improved.

  In addition, when providing a plurality of variation patterns that specify reach effects with different performance contents and expectation degree of jackpot, the main control CPU 30a performs the variation pattern after the processing of step SA5 or step SA7 of the special figure input process. May be determined in advance, and a change prefetch command capable of specifying the determined change pattern may be output to the effect control CPU 31a. Then, the effect control CPU 31a controls the effect display device 11 to display the hold change effect by changing the display mode of the hold image G so as to reach the upper limit stage corresponding to the change pattern indicated by the change look-ahead command. May be.

  The CPU 31a for effect control displays the special reserved image G2 as the reserved image G corresponding to the starting reserved ball based on the winning when the starting winning ports 17 and 18 win, and the winning of the starting winning ports 17 and 18 is won. At the same time, the hold change effect may be started. In this case, the effect control CPU 31a may set a value indicating the number of the start holding balls designated by the hold designation command as the determination end value in step SB10 of the command input process. In addition to the production patterns YP0 and YP1, the production pattern YP2 is associated with the production distribution table TA, and when the production pattern YP2 is selected, the production control CPU 31a applies all of the start-up balls in the process of step SB4. You may make it set "01H" to the corresponding present state flag F2. According to such a configuration, it is possible to create a situation where the special hold image G2 is displayed from the beginning and the hold change effect is started, and a situation where the hold change effect is not started. Therefore, when the hold change effect is started together with winning at the start winning openings 17, 18, it is displayed whether the big hit expectation degree of the symbol variation game corresponding to the newly displayed special hold image G2 is high. It can be made difficult to grasp whether the big hit expectation degree of the symbol variation game corresponding to the reserved image G that has been held is high.

  The effect control CPU 31a may change the display mode of the hold image G based on different control commands. For example, each time the main control CPU 30a detects a game ball by using the switches SW1 to SW3 described above or a switch provided in a normal winning opening as a ball opening provided in the game board 10, the effect control is performed on a prize ball payout start command. Output to the substrate 31 (production control CPU 31a). The main control CPU 30a adds the number of prize balls every time a game ball is detected by these switches, while subtracting the number of prize balls every time a prize ball is paid out from a prize ball payout device (not shown). To manage the total number of unpaid prize balls. The main control CPU 30a then outputs a prize ball payout end command to the effect control board 31 (effect control CPU 31a) when the total number of prize balls reaches 0 (zero). Further, the effect control CPU 31a is triggered by the input of the prize ball payout start command, and blinks the prize ball payout lamp (notification means) connected to the effect control CPU 31a to notify that the prize ball is being paid out. On the other hand, with the input of a prize ball payout end command, the prize ball payout lamp is turned off to notify that the prize ball is not being paid out. Then, the effect control CPU 31a may perform the process of steps SB6 to SB11 of the command input process in response to the input of the prize ball payout start command. If comprised in this way, the display mode of the hold | maintenance image G can be changed with the winning to the start winning ports 17, 18, the normal winning port, the big winning port, or the like. Therefore, it is possible to use both a command for controlling the winning ball payout lamp and a command for executing the hold change effect.

  -The effect control CPU 31a out of the game balls launched into the game area of the game board 10 as the entrance for discharging the game balls that have not entered any of the winning entrances to the outside. The process of steps SB6 to SB11 of the command input process may be performed in response to the game ball entering the mouth. Further, the effect control CPU 31a may perform the process of steps SB6 to SB11 of the command input process when the game ball that has passed through the gate 22 as the entrance is detected by the gate switch SW4. According to this, the hold change effect can be started when the game ball enters the outlet or the gate 22.

  In the special figure input process, it may be determined in advance whether or not a big hit will be made in the probability change state, and the hold change effect may be executed based on the result. In this case, when the determination result in step SA5 is negative in the special chart input process shown in FIG. 6, the main control CPU 30a compares the big hit determination random number value with the non-common value among the big hit determination values, Pre-determine whether the values match. In other words, the main control CPU 30a has a symbol variation game based on the value of the jackpot determination random number (the number of reserved storage) stored in the special chart input process in the current control cycle, and the gaming state at the time of the jackpot determination is a probabilistic state. It is determined in advance whether or not it will be a big hit on the condition. If this determination result is negative, the main control CPU 30a proceeds to the processing of step SA7, whereas if the determination result is affirmative, a specific prefetch command in which a value different from the prefetch command [E1xxH] is set in the upper byte is determined. It is generated in the same manner as the processing in step SA6 and set in the output buffer. Thereafter, the main control CPU 30a ends the special figure input process. Then, when the specific prefetch command is input, the effect control CPU 31a may perform the command input process on the condition that the gaming state at that time is a probable change state, and execute the hold change effect.

-The process of step SB8 of the command input process may be omitted, and the hold change effect may be always started when the determination result of step SB7 is affirmative.
The display mode of the hold image G (hold image G1, G2) may be changed, for example, such as a tricycle → bicycle, or a hold image imitating a bud → flower. Further, the hold image G may be displayed on a display device provided separately from the effect display device 11. Further, the hold change effect may be executed by changing the display mode of the special symbol hold light emitting unit in the special figure hold display device 13. In this case, it is good also as a structure which does not display the hold image G on the production | presentation display apparatus 11. FIG.

  -You may make it not start a holding | maintenance change production by the input of a 5th holding designation command. In this case, the configuration for outputting the fifth hold designation command may be omitted. Even with such a configuration, the display mode of the hold image G can be changed based on the second to fourth hold designation commands.

-Steps SA7 to SA9 in the special figure input process may be omitted, and only a prior determination as to whether or not a big hit has been made may be performed.
A game machine that executes an image change effect as a special effect that is performed by changing the display mode of the effect image displayed on the effect display device 11 from the normal display mode to the special display mode instead of or in addition to the hold change effect. You may apply. Even with such a configuration, it is possible to have a willingness to continuously launch game balls. Therefore, it is possible to improve the interest in the hold change effect while suppressing the player from stopping the launch of the game ball.

The effect display device 11 may be a dot matrix type, an organic EL type, a plasma display type, or the like, or a display device that combines these.
A pachinko machine equipped with a sub-control board for controlling the sub-control board, and a sub-control board such as a display control board for controlling the effect display device 11 and a sound control board for controlling the speaker, The present invention may be embodied in a pachinko gaming machine including a single control board that integrally includes the functions of the main control board 30 and the effect control board 31.

  The special symbol designating command for designating the special symbol may be a control command that can specify the type of the special symbol to be confirmed and stopped in the symbol variation game. That is, the special figure designation command may be a control command that can specify the type of jackpot symbol (special type of jackpot) of the special symbol. Further, the variation pattern may be configured to be able to specify the determination result of the big hit determination (big hit lottery) and the type of special symbol (in the case of the big hit symbol, the type of big hit).

The first special figure variation game based on the detection of entering the ball into the first start winning opening 17 and the second special figure variation game based on the detection of entering the second start winning opening 18 may be performed separately. .
The special figure display device 12 may also be used as the effect display device 11 by causing the effect display device 11 to display special symbols. Moreover, it is good also as a structure which abbreviate | omits the production | presentation display apparatus 11, and does not display the symbol change game by a decoration symbol.
