Fired sequentially on the board 14.

  It should be noted that the touch sensor provided on the firing handle 26 may be any sensor as long as it can be determined that the player has held the firing handle 26. It doesn't matter.

  The launched game ball is guided to a guide rail 30 provided on the game board 14 and moves to the upper part of the game board 14. After that, the game ball is changed in its traveling direction by collision with the above-described obstacle nails. It falls toward the bottom of the board 14. Thus, an area surrounded by the guide rail 30 and into which a game ball can be thrown is referred to as a game area.

  A liquid crystal display device 32 as a variable display means is provided in the approximate center of the front surface of the game board 14. The liquid crystal display device 32 has a display area 32a, and identification information is variably displayed in the display area 32a. Further, such identification information is configured as a special symbol 92 in the special symbol game. Details of the special symbol game will be described later. This identification information is a pattern made up of numbers, symbols, and the like. In this embodiment, numbers from “0” to “9” are used.

  “Variable display” is a concept that can be displayed in a variable manner. For example, a “variable display” that is actually displayed in a variable state, a “stop display” that is displayed in a stopped state, etc. It is. In addition, “variable display” can be “derivation display” in which identification information is displayed as a result of a special symbol game. Further, the period from the start of the variable display to the derivation display is referred to as one variable display.

  Further, identification information corresponding to a plurality of symbol rows (three rows in the present embodiment) is variably displayed on the liquid crystal display device 32. Identification information is derived and displayed in the plurality of symbol sequences, and the combination of the plurality of identification information derived and displayed is a specific display mode (for example, any one of “0” to “9” in each of the plurality of symbol sequences). The game state is shifted to a jackpot state (so-called jackpot) that is advantageous to the player based on the fact that the game is derived and displayed in a state in which all of them are arranged, so-called “hit display mode”). In addition to the identification information, the liquid crystal display device 32 displays a background image, an effect image for effect, a normal symbol image, and the like. In the present embodiment, the identification information is composed of a plurality of symbol strings. However, the present invention is not limited to this. For example, the identification information may be composed of one symbol string.

  A sphere passage detector 54 is provided on the left side of the liquid crystal display device 32. When the ball passage detector 54 detects that a game ball has passed in the vicinity thereof, the normal symbol 94 is displayed on the display area 32a. After a predetermined time has elapsed, the normal symbol change display is displayed. To stop. This normal symbol is information including numbers, symbols, and the like, for example, symbols such as “◯” and “x”. Further, a normal symbol holding lamp 50 for displaying the number of holdings in the normal symbol game is provided on the side of the liquid crystal display device 32. In addition, an upper limit (for example, 4) is set for the number of holds in the normal symbol game.

  When the normal symbol is stopped and displayed as a predetermined symbol, for example, “◯”, the blade members (so-called normal electric accessories) 48 provided on the left and right sides of the starting port 44 described later are in the open state from the closed state. Thus, it becomes easier for a game ball to enter the start port 44. In addition, when a predetermined time has elapsed after the blade member 48 is in the open state, the blade member 48 is closed so that it is difficult for the game ball to enter the start port 44.

  In the present embodiment, the liquid crystal display device 32 including a liquid crystal display panel is employed as a portion for displaying an image. However, the present invention is not limited to this, and other modes may be used. For example, a CRT (Cathode Ray Tube) is used. It may be composed of a cathode ray tube, a dot LED, a segment LED, an EL (Electronic Luminescent), plasma, or the like. Further, in the present embodiment, the liquid crystal display device 32 is shown in the case where the liquid crystal display device 32 is provided in the approximate center of the front surface of the game board 14 in the pachinko gaming machine 10 that is a ball game machine, but the position that can be visually recognized by the player. If so, the liquid crystal display device 32 may be provided at any position. In this embodiment, the identification information and the normal symbol are variably displayed on the liquid crystal display device 32. However, the present invention is not limited to this, and a variable symbol display device for the normal symbol is provided separately from the liquid crystal display device 32. It may be configured. Further, the liquid crystal display device 32 is adopted as the variable display means. However, the present invention is not limited to this, and other modes may be adopted.

  Furthermore, on both the left and right sides of the liquid crystal display device 32, rolling guide members 59a and 59b for guiding the path of the game ball in a predetermined direction are also provided. In addition, decorative lamps 36a and 36b are provided on the lower left side and the lower right side of the game board 14, respectively.

  Above the liquid crystal display device 32 described above, four holding lamps 34a to 34d are provided. In addition, at the lower part of the game board 14, there are provided game balls general winning ports 56 a to 56 d.

  In the vicinity of the general winning ports 56a to 56d, a shutter 40 that can be opened and closed with respect to a large winning port (not shown) is provided. That is, the big winning opening is provided in the game area. When the combination of the identification information derived and displayed as described above is a specific display mode, the gaming state is shifted to the big hit gaming state, and the shutter 40 is in an open state (first state) in which it is easy to accept the gaming ball. To be driven. Further, the special winning opening has a specific area (not shown) having a V / count sensor 102 (see FIG. 2) and a general area (not shown) having a count sensor 104 (see FIG. 2). The shutter 40 is driven to the open state until a predetermined number (for example, 10) of game balls pass through these areas or until a predetermined time (for example, 30 seconds) elapses. In other words, when either of the conditions for winning a predetermined number of game balls in the grand prize opening or the elapse of a predetermined time is satisfied in the open state, the big prize opening is closed so that it is difficult to accept the game balls. Subsequently, the shutter 40, which has been changed from the open state to the closed state (second state), is once again on condition that the game ball received in the big winning opening in the open state has passed through the V-count sensor 102. Driven to the open state. That is, the game ball received when the grand prize winning opening is in the open state passes the specific area provided in the big winning prize opening, and then is opened again after being closed.

  A start opening 44 having a start winning ball sensor 116 (see FIG. 2) is provided below the liquid crystal display device 32. When a game ball wins at the starting port 44, a special symbol game, which will be described later, is started, and the state shifts to a variable display state in which a plurality of columns of identification information are displayed in a variable manner. In the present embodiment, the variable display start condition for the predetermined identification information is mainly based on the fact that a game ball has won a winning opening 44. In addition, it is also a condition that the identification information is derived and displayed. That is, the variable display of the identification information is performed every time the variable display start condition for the predetermined identification information is satisfied. In the embodiment, the predetermined display information variable display start condition is that a game ball has been won at the start port 44, but the present invention is not limited to this.

  Further, when a game ball is won at the start opening 44 during the variation display of the identification information in the special symbol game, the game ball is won at the start opening 44 until the identification information during the variation display is derived and displayed. Execution (start) of variable display of the identification information based is suspended. If the identification information is derived and displayed in a state where execution of variable display of the identification information is suspended, execution of variable display of the identification information held is started. In addition, when the identification information is derived and displayed, the variable display of the identification information is executed once. For example, when the identification information is derived and displayed in a state where execution of variable display of the identification information is held three times, one of the variable display of the held identification information is executed, and the remaining 2 The batch is held.

  The number of executions of variable display of the identification information being held (so-called “hold number”, “hold number related to special symbols”) is displayed by turning on / off the hold lamps 34a to 34d. For example, when execution of variable display of identification information is held for one time, the hold lamp 34a is turned on and the hold lamps 34b to 34d are turned off. When execution of variable display of the identification information is held twice, the holding lamps 34a and 34b are turned on and the holding lamps 34c and 34d are turned off. When execution of variable display of the identification information is held three times, the holding lamps 34a to 34c are turned on and the holding lamp 34d is turned off. When the variable display of the identification information is held four times, the hold lamps 34a to 34d are turned on.

  An upper limit is set for the number of executions of the variable display of the identification information to be held. For example, the variable display of the identification information is held up to 4 times. For example, in the state where execution of variable display of identification information is held three times, when a game ball wins the start opening 44, execution of the fourth time is held, but execution of variable display of identification information is executed. If the game ball wins the start port 44 in a state where it is held for four times, the fifth execution is not held, and the state where the variable display of the identification information is held for four times is maintained. It becomes.

  Similarly, in the normal symbol game, when a game ball passes in the vicinity of the ball passage detector 54 during the normal symbol variation display, the ball is displayed until the normal symbol in the variation display is derived and displayed. Execution (start) of variable symbol display based on the passing of the game ball to the passage detector 54 is suspended. If the normal symbol is derived and displayed in the state where the execution of variable display of the normal symbol is suspended, the variable symbol of the held regular symbol is started after a predetermined time has elapsed. Further, the execution of variable display of the normal symbol executed when the normal symbol is derived and displayed is one time. The number of executions of the variable display of the held normal symbol (so-called “the number of holdings related to the normal symbol”, “the number of holdings in the normal symbol game”) is expressed by turning on / off the normal symbol holding lamp 50. In addition, an upper limit is also set for the number of times that execution of variable symbol display is suspended, for example, variable symbol variable display is suspended up to four times.

  In the present embodiment, the variable information display is suspended with the upper limit being four times. However, the present invention is not limited to this. For example, one or more times may be set as the upper limit. As such, the variable display of the identification information may be suspended, and further, the identification information may be suspended without setting an upper limit. Of course, you may comprise so that the variable display of identification information may not be suspended. In the present embodiment, the variable symbol display is suspended with the upper limit being four times. However, the present invention is not limited to this. For example, the upper limit may be one or more times. As such, it may be configured to hold the variable display of the normal symbol, or may be configured to hold without setting an upper limit. Of course, you may comprise so that the variable display of a normal symbol may not be suspended.

  In addition, when a game ball wins or passes through the specific area and the general area in the start opening 44, the general winning openings 56a to 56d, and the large winning opening, the number set in advance according to the type of each winning opening. A game ball is paid out to the upper plate 20 or the lower plate 22.

[Main processing]
First, as shown in FIG. 4, initial setting processing such as RAM access permission, backup restoration processing, and work area initialization is executed (step S11). Then, as will be described in detail later with reference to FIG. 7, a special symbol control process relating to the progress of the special symbol game and the identification information displayed on the liquid crystal display device 32 is executed (step S15). Then, the normal symbol control process for the normal symbol game is executed and the normal symbol displayed on the liquid crystal display device 32 is executed (step S16). As described above, in the main process, after the initial setting process in step S11 is completed, the processes in step S15 and step S16 are repeatedly executed.

[System timer interrupt processing 1]
Further, the main CPU 66 may interrupt the main process and execute the system timer interrupt process even when the main process is being executed. The following system timer interrupt processing 1 is executed in response to a clock pulse generated from the reset clock pulse generation circuit 62 at a predetermined cycle (for example, 160 μs). This system timer interrupt process will be described with reference to FIG.

  First, as shown in FIG. 5, the main CPU 66 executes a random number update process so that each count value of the big hit symbol determination random number counter, etc., excluding the big hit determination random number counter described above is incremented by “1” ( Step S42). And the input detection process which detects the winning or passing of game balls, such as the starting port 44, the ball passage detector 54, and the general winning ports 56a to 56d, is executed (step S43). When the game ball wins the start opening 44, the main CPU 66 performs only the process related to the winning ball based on the winning of the gaming ball, and extracts the jackpot determination random number value from the jackpot determination random number counter. Is not performed, and is executed in step S63 shown in FIG. A waiting time timer for synchronizing the main control circuit 60 and the sub control circuit 200, a big prize opening time timer for measuring the opening time of the big prize opening that is opened when a big hit occurs, and the like. The timer update process is executed (step S44). Then, an output process is executed in order to supply a signal for drive control based on various variables to a solenoid, a motor or the like (step S46). If this process ends, the process moves to a step S47.

  In step S47, command output processing is executed. In this process, the main CPU 66 supplies various commands to the sub control circuit 200. Specifically, these various commands include a demo display command, a derived symbol designation command indicating the type of identification information derived and displayed in the left column, middle column, and right column, and a variation indicating a variation display pattern of the identification information. Includes pattern specification commands. If this process ends, the process moves to a step S49.

  In the process of step S49, the main CPU 66 executes a payout process such as transmitting a command for causing the payout device 128 to play a prize ball to the payout / launch control circuit 126 (step S49). When this process is finished, this subroutine is finished, the address is returned to the address before the occurrence of the interrupt, and the main process is executed.

[System timer interrupt processing 2]
Further, the main CPU 66 may interrupt the main process and execute the system timer interrupt process even when the main process is being executed. The following system timer interrupt process 2 is executed in response to a clock pulse generated every predetermined period (for example, 160 μs) from the reset clock pulse generation circuit 62. The system timer interrupt process 2 is a process having a higher priority than the system timer interrupt process 1. That is, the system timer interrupt process 2 is a process having a shorter period than the system timer interrupt process 1 and a higher priority than the system timer interrupt process 1. The system timer interrupt process 2 will be described with reference to FIG.

  First, as shown in FIG. 6, the main CPU 66 executes a start port detection time process, which will be described later in detail with reference to FIG. 10 (step S51). Then, the main CPU 66 increments and stores the big hit determination random number value stored in the big hit determination random number counter by “1” (step S52). Subsequently, the main CPU 66 reads the jackpot determination random number value from the jackpot determination random number counter, and determines whether or not the jackpot determination random number value is the maximum jackpot determination random number (for example, “350”) ( Step S53). If the main CPU 66 determines that the jackpot determination random number value is the maximum jackpot determination random number value, the main CPU 66 shifts the processing to step S54. On the other hand, if the main CPU 66 does not determine that the jackpot determination random number value is the maximum jackpot determination random number value, the main CPU 66 shifts the processing to step S55.

  In step S54, the main CPU 66 sets “0” in the jackpot determination random number counter. If this process ends, the process moves to a step S55.

  In step S55, the main CPU 66 performs a process of updating the jackpot determination random number counter. As a result, the big hit determination random number counter is updated in the range of “0” to “349”. When this process is finished, this subroutine is finished, the process returns to the address before the occurrence of the interrupt, and the main process or the system timer interrupt process 1 is executed.

  By executing such processing, it is possible to prevent fraudulent acts against the update processing of the random number counter for determining the transition to the jackpot state as much as possible. Further, it is possible to prevent fraudulent acts on the processing related to the update of the random number counter for determining the transition to the big hit state as much as possible.

[Special symbol control processing]
The subroutine executed in step S15 in FIG. 4 will be described with reference to FIG. In FIG. 7, the numerical values drawn on the sides of step S72 to step S80 indicate control state flags corresponding to those steps, and one step corresponding to the numerical value according to the numerical value of the control state flag. Will be executed and the special symbol game will proceed.

  First, as shown in FIG. 7, a process for loading a control state flag is executed (step S71). In this process, the main CPU 66 reads the control state flag. If this process ends, the process moves to a step S72.

  In steps S72 to S80, which will be described later, the main CPU 66 determines whether or not to execute various processes in each step based on the value of the control state flag, as will be described later. This control state flag indicates the state of the special symbol game, and enables one of the processes from step S72 to step S80 to be executed. In addition, the main CPU 66 executes processing in each step at a predetermined timing determined according to a waiting time timer or the like set for each step. Before reaching the predetermined timing, the process ends without executing the process in each step, and another subroutine is executed. Of course, the system timer interrupt process 1 and the system timer interrupt process 2 are also executed at a predetermined cycle.

  In step S72, a special symbol memory check process is executed. As will be described in detail later with reference to FIG. 9, the main CPU 66 checks the number of holdings when the control state flag is a value (00) indicating a special symbol storage check, and determines the big hit if there is a holding number. The derivation identification information, the variation pattern of the identification information, etc. are determined. Further, the main CPU 66 sets a value (01) indicating special symbol variation time management in the control state flag, and sets the variation time corresponding to the variation pattern determined in the current process in the waiting time timer. That is, it is set so that the process of step S73 is executed after the fluctuation time corresponding to the fluctuation pattern determined this time has elapsed. On the other hand, when there is no pending number, a demonstration screen is displayed. If this process ends, the process moves to a step S73.

  In step S73, a special symbol variation time management process is executed. In this process, the main CPU 66 sets the control state flag to a value (01) indicating special symbol change time management, and when the change time has elapsed, sets the value (02) indicating special symbol display time management to the control state flag. And a waiting time after confirmation (for example, 1 second) is set in the waiting time timer. That is, it is set so that the processing of step S74 is executed after the waiting time after determination has elapsed. If this process ends, the process moves to a step S74.

  In step S74, a special symbol display time management process is executed. In this process, the main CPU 66 determines whether or not it is a big hit when the control state flag is a value (02) indicating special symbol display time management and the waiting time after determination has elapsed. In the case of a big hit, the main CPU 66 sets a value (03) indicating the big hit start interval management in the control state flag, and sets a time (for example, 10 seconds) corresponding to the big hit start interval in the waiting time timer. That is, after the time corresponding to the big hit start interval elapses, the setting of step S75 is performed. On the other hand, the main CPU 66 sets a value (08) indicating the end of the special symbol game when it is not a big hit. That is, it is set to execute the process of step S80. If this process ends, the process moves to a step S75.

  In step S75, a big hit start interval management process is executed. In this processing, the main CPU 66 has a value (03) indicating that the control status flag indicates the jackpot start interval management, and when the time corresponding to the jackpot start interval has elapsed, Based on the data read from the ROM 68, the variables positioned in the main RAM 70 are updated. The main CPU 66 sets a value (04) indicating that the special winning opening is being opened to the control state flag, and sets an open upper limit time (for example, 30 seconds) to the special winning opening open timer. That is, it is set to execute the process of step S77. If this process ends, the process moves to a step S76.

  In step S76, a waiting time management process before reopening the big winning opening is executed. In this process, the main CPU 66 sets the special prize opening number counter when the control status flag is a value (06) indicating the big prize opening reopening waiting time management and the time corresponding to the interval between rounds has elapsed. The memory is updated so that “1” is increased. The main CPU 66 sets a value (04) indicating that the special winning opening is open in the control state flag. The main CPU 66 sets an opening upper limit time (for example, 30 seconds) in the big prize opening time timer. That is, it is set to execute the process of step S77. If this process ends, the process moves to a step S77.

  In step S77, a special winning opening opening process is executed. In this process, when the control state flag is a value (04) indicating that the big prize opening is open, the condition that the big prize opening prize counter is “10” or more and the upper limit opening time have elapsed. It is determined whether or not any of the conditions (the big prize opening time timer is “0”) is satisfied. The main CPU 66 updates a variable positioned in the main RAM 70 in order to close the special winning opening when any of the conditions is satisfied. The main CPU 66 sets a value (05) indicating monitoring of the winning ball remaining ball in the control state flag. The main CPU 66 sets the special ball remaining ball monitoring time (for example, 1 second) in the waiting time timer. That is, it is set so that the process of step S78 is executed after the winning ball residual ball monitoring time has elapsed. Note that the main CPU 66 does not execute the above-described processing when none of the conditions is satisfied. If this process ends, the process moves to a step S78.

  In step S78, a special winning opening residual ball monitoring process is executed. In this process, the main CPU 66 has a value (05) indicating that the control state flag indicates the monitoring of the winning ball residual ball and when the monitoring time of the winning ball residual ball elapses, the main CPU 66 sets the game ball in the specific area at the winning game mouth. It is determined whether or not the condition that the winning prize opening number counter is “15” or more (the final round) is satisfied. When any of the conditions is satisfied, the main CPU 66 sets a value (07) indicating the jackpot end interval in the control state flag, and sets a time corresponding to the jackpot end interval in the waiting time timer. In other words, after the time corresponding to the big hit end interval has elapsed, the setting of step S79 is executed. On the other hand, when neither of the conditions is satisfied, the main CPU 66 sets a value (06) indicating management of the special winning opening reopening waiting time in the control state flag. Further, the main CPU 66 sets a time corresponding to the interval between rounds in the waiting time timer. In other words, after the time corresponding to the interval between rounds has elapsed, the setting of step S76 is executed. If this process ends, the process moves to a step S79.

  In step S79, a big hit end interval process is executed. In this process, the main CPU 66 controls the value (08) indicating the end of the special symbol game when the control state flag is a value (07) indicating the jackpot end interval and the time corresponding to the jackpot end interval has elapsed. Set the status flag. The main CPU 66 sets a high probability flag in order to change the jackpot probability when a predetermined probability change condition is satisfied. That is, it is set to execute the process of step S80. If this process ends, the process moves to a step S80.

  In step S80, a special symbol game end process is executed. In this processing, when the control state flag is a value (08) indicating the end of the special symbol game, the main CPU 66 stores and updates the data indicating the number of holdings so as to decrease by “1”. The main CPU 66 updates the special symbol storage area in order to perform the next fluctuation display. The main CPU 66 sets a value (00) indicating a special symbol storage check. That is, it is set to execute the process of step S72. When this process is finished, this subroutine is finished.

  As described above, the special symbol game is executed by setting the control state flag. Specifically, as shown in FIG. 8, the main CPU 66 sets the control status flag to “00”, “01”, “02”, “ By setting “08 ″ in order, the processing of step S72, step S73, step S74, and step S80 shown in FIG. 7 is executed at a predetermined timing. Further, the main CPU 66 sets the control state flag in the order of “00”, “01”, “02”, “03” when the result of the big hit determination is a big hit when it is not the big hit state. Steps S72, S73, S74, and S75 shown in FIG. 7 are executed at a predetermined timing, and the control to the big hit state is executed. Furthermore, the main CPU 66 sets the control state flags in order of “04”, “05”, and “06” when the control to the big hit state is executed, so that step S77 shown in FIG. The processing of S78 and step S76 is executed at a predetermined timing, and the jackpot game is executed. When the jackpot game is being executed, if the jackpot state end condition (the jackpot game end condition) is satisfied, “04”, “05”, “07”, “08” should be set in order. Thus, the processing from step S77 to step S80 shown in FIG. 7 is executed at a predetermined timing, and the jackpot state is terminated. It should be noted that the jackpot game end condition is that there is no passing of a game ball to a specific area (so-called “puncture”) until a predetermined time elapses, or the jackpot round maximum continuation number (in this embodiment, The jackpot state will be terminated on condition that (15 rounds) has been completed.

[Special symbol memory check processing]
The subroutine executed in step S72 in FIG. 7 will be described with reference to FIG.

  First, as shown in FIG. 10, it is determined whether or not the control state flag is a value (00) indicating a special symbol storage check (step S101), and the control state flag is a value indicating a special symbol storage check. If it is determined that there is, the process proceeds to step S102. If it is not determined that the control state flag is a value indicating a special symbol storage check, this subroutine is terminated. In step S102, it is determined whether or not the reserved number is “0”. If it is determined that the data indicating the reserved number is “0”, the process proceeds to step S103, and the reserved number is stored. If it is not determined that the data indicating “0” is “0”, the process proceeds to step S104.

  In step S103, a demonstration display process is executed. In this process, the main CPU 66 stores a variable for supplying a demonstration display command to the sub control circuit 200 in the main RAM 70 in order to perform a demonstration display. As a result, the display of the demonstration screen is executed in the sub-control circuit 200. When this process is finished, this subroutine is finished.

  In step S104, a process of setting a value (01) indicating special symbol variation time management as a control state flag is executed. In this process, the main CPU 66 stores a value indicating special symbol variation time management in the control state flag. If this process ends, the process moves to a step S105.

  In step S105, a jackpot determination process is executed. In this process, the main CPU 66 selects a jackpot determination table. Then, the main CPU 66 refers to the jackpot determination random number value extracted at the time of starting winning and the selected jackpot determination table. In other words, the main CPU 66 determines whether or not the jackpot state is advantageous to the player. If this process ends, the process moves to a step S106.

  In step S106, it is determined whether or not it is a big hit. In this process, the main CPU 66 determines whether or not it is a big hit based on the result of the reference in step S105. If the main CPU 66 determines that it is a big hit, it moves the process to step S107, and if it does not determine that it is a big hit, moves the process to step S108.

  In step S107, a jackpot symbol determination process is executed. In this process, the main CPU 66 extracts the jackpot symbol random value extracted at the time of starting winning, and determines identification information corresponding to the left column, the middle column, and the right column based on the jackpot symbol random value, Data indicating the identification information is stored in a predetermined area of the main RAM 70. The data indicating the identification information corresponding to the left column, the middle column, and the right column stored in this manner is derived from the main CPU 66 of the main control circuit 60 to the sub CPU 206 of the sub control circuit 200 by the process of step S47 in FIG. Supplied as a symbol designating command. If this process ends, the process moves to a step S109.

  In step S108, a missing symbol determination process is executed. In this process, the main CPU 66 extracts a random symbol value for determining an out symbol from the random symbol counter for determining an out symbol, and determines identification information corresponding to the left column, the middle column, and the right column based on the random symbol value for determining the out symbol. Then, data indicating the identification information is stored in a predetermined area of the main RAM 70. The data indicating the identification information corresponding to the left column, the middle column, and the right column stored in this manner is derived from the main CPU 66 of the main control circuit 60 to the sub CPU 206 of the sub control circuit 200 by the process of step S47 in FIG. Supplied as a symbol designating command. By executing such processing, that is, the result of variable display of the identification information is determined.

  When the left column and the right column have the same identification information, and the left column and the middle column have the same identification information, the main CPU 66 sets the middle column identification information as a predetermined number of frames (for example, (3 frames) is determined to be corrected, and control is performed so as not to be a big hit. That is, by this step, the result of variable display of identification information is determined before the result of variable display of identification information is derived and displayed. If this process ends, the process moves to a step S109.

  In step S109, a variation pattern determination process is executed. In this process, the main CPU 66 extracts a rendering condition selection random value. The main CPU 66 selects a variation pattern distribution table for determining a variation pattern based on the identification information of the left column, the middle column, and the right column determined in steps S107 and S108. The main CPU 66 determines a variation pattern based on the rendering condition selection random number extracted from the rendering condition selection random number counter and the selected variation pattern distribution table, and stores the variation pattern in a predetermined area of the main RAM 70. The data indicating the variation pattern stored in this way is supplied as a variation pattern designation command from the main CPU 66 of the main control circuit 60 to the sub CPU 206 of the sub control circuit 200 by the process of step S47 of FIG. The sub CPU 206 of the sub control circuit 200 executes an effect display according to the received variation pattern designation command. If this process ends, the process moves to a step S110.

  In step S110, a process of setting a variation time corresponding to the determined variation pattern in the waiting time timer is executed. In this process, the main CPU 66 calculates the fluctuation effect time based on the fluctuation pattern determined by the process of step S109 and the fluctuation effect time table indicating the fluctuation effect time of the fluctuation pattern, and the fluctuation effect time. Is stored in the waiting time timer. Then, a process of clearing the storage area used for the current variation display is executed (step S111). When this process is finished, this subroutine is finished.

[Start-up port detection process]
The subroutine executed in step S51 in FIG. 6 will be described with reference to FIG.

  First, as shown in FIG. 10, a start port switch input detection process is executed (step S61). The main CPU 66 detects whether or not the game ball has won the start opening 44 depending on whether or not a predetermined detection signal is supplied from the start winning ball sensor 116. Then, the main CPU 66 determines whether or not there is a switch input (step S62). If the main CPU 66 determines that there has been a switch input, the main CPU 66 extracts the big hit determination random number value from the big hit determination random number counter, stores it in a predetermined storage area of the main RAM 70 (step S63), and executes this subroutine. finish. On the other hand, if the main CPU 66 does not determine that there has been a switch input, the main CPU 66 ends this subroutine.

[Operation of sub-control circuit]
On the other hand, the sub control circuit 200 receives various commands transmitted from the main control circuit 60 and executes the following effects.

  For example, when the sub CPU 206 receives a variation pattern designation command, the sub CPU 206 selects an effect pattern corresponding to the variation pattern designation command based on the variation pattern designation command, and selects the selected effect pattern in a predetermined area of the work RAM 210. Set to. Further, when receiving the derived symbol designation command, the sub CPU 206 determines a stop symbol based on the derived symbol designation command and sets it in the work RAM 210.

  Then, based on the derived symbol designation command, the variation pattern designation command, etc., the sub CPU 206 identifies identification information images corresponding to the left column, the middle column, and the right column in the display area 32a of the liquid crystal display device 32 (in the special symbol game).
