When the normal symbol display device 41 detects that the game ball passes through the normal symbol operation gate 32, the normal symbol display device 41 performs variable display by sequentially switching the four display modes. The display is stopped in one of the display modes. At this time, when the stop-displayed display mode is a specific display mode (for example, the display mode shown in FIG. 6D), the ordinary electric accessory 38 is held for a certain period of time (for example, 0.5 seconds). To open. When the game ball passes the normal symbol operation gate 32a during the normal symbol fluctuation display, the normal symbol fluctuation display is held up to four times, and when the current fluctuation display ends, it is held. The variable display is digested sequentially. It should be noted that the number of hold of the normal symbol variation display is displayed by the normal symbol hold lamp 35b (see FIG. 8 described later).

  As shown in FIG. 5, the special symbol display device 42 includes a left special symbol display unit 42 a and a right special symbol display unit 42 b configured using a seven-segment display, and each segment is turned on and off. A plurality of display modes (up to 128) are expressed by combinations.

When the game ball wins the start opening 36 during the special symbol fluctuation display, the special symbol fluctuation display is held up to four times, and when the current fluctuation display is finished, the held fluctuation display is sequentially displayed. Digested. It should be noted that the number of the special symbol variation display hold is displayed by a special symbol hold lamp 35a (see FIG. 8 described later).

  Here, in the first normal jackpot, a jackpot game in which the opening operation of the big winning opening 44 is repeated over a predetermined number of rounds (for example, 15 rounds) is performed, and after the jackpot game is over, a predetermined number of times (for example, In the big hit mode in which the normal symbol variation time is shortened and the opening time of the ordinary electric accessory 38 is extended (so-called “short time”) when the normal symbol is stopped and displayed. is there. After the big hit, the normal mode (also referred to as a low probability mode) has a low probability that the big hit determination result is a big hit. As in the first normal jackpot, the first winning jackpot game is a jackpot game in which the opening operation of the jackpot 44 is repeated over a predetermined number of rounds (for example, 15 rounds). Then, the probability change mode is a probability variation mode (also referred to as a high probability mode) in which the probability of a big hit determination is higher than that in the normal mode, and the time is short until the next big hit is drawn. In addition, in the second probability variation big hit, a big hit game in which the opening of the big winning opening 44 is repeated over a smaller number of rounds (for example, two rounds) than the first normal big hit is performed, but after the big hit game ends Then, the probability variation mode is entered and the time is shortened until the next big hit.

  The effect display device 34 is configured as a display device such as a liquid crystal display. As shown in the screen configuration illustrated in FIG. 8, the effect display device 34 has three effect symbols (pseudo special symbols) 34 </ b> L and 34 </ b> M arranged side by side and composed of characters and numbers. , 34R and a background pattern (not shown). The effect display device 34 variably displays the three effect symbols 34L, 34M, and 34R when detecting that the game ball wins the start opening 36. In FIG. 9, an example of the change display and stop display of the effect symbol of the effect display device 34 is shown. The production symbols 34L, 34M, and 34R are variably displayed so as to scroll at a high speed from the top to the bottom when the variation display is started. When the execution time of the variation display elapses, the production symbols 34L, right on the left The effect symbols 34R and the middle effect symbol 34M are stopped and displayed in this order. At this time, when the left effect symbol 34L and the right effect symbol 34R do not match, it becomes a simple disengagement without reach (see FIG. 9A), and the left effect symbol 34L and the right effect symbol 34R are separated. Reach when they match. When the middle production symbol 34M stops with a predetermined reach production and the middle production symbol 34M and the left and right production symbols 34L and 34R do not match, it is determined that the reach is lost (FIG. 9B). )), A big hit is obtained when the middle production symbol 34M and the left and right production symbols 34L and 34R coincide (see FIG. 9C). The result of success or failure of the effect symbol displayed on the effect display device 34 basically matches the result of success or failure of the special symbol displayed by the special symbol display device 42 described above. Each effect symbol 34L, 34M, 34R is scrolled in a semi-transparent state during the variable display, and is displayed in a state that is clearly visible when it is stopped.

  In the present embodiment, the effect display device 34 also displays a special symbol hold lamp 35a and a normal symbol hold lamp 35b in the display screen. The special symbol holding lamp 35a is turned on one by one from the left every time a game ball is won at the start port 36 during the special symbol variation display, and is reverse to the lighting every time the special symbol variation display is started. The lights are turned off in sequence. The normal symbol holding lamp 35b is also lit one by one from the left each time the game ball passes through the normal symbol operating gate 32 during the normal symbol variation display, and is lit every time the normal symbol variation display is started. The lights are turned off in the reverse order.

FIG. 13 is a flowchart illustrating an example of main control processing executed by the CPU 70a of the main control board 70. This process is executed when the power of the pachinko machine 10 is turned on. The main control process executes a power-on process necessary for power-on such as an initialization process (step S100), a game start process (step S110), a normal symbol game process (step S120), and a game per normal symbol The process (step S130), the special symbol game process (step S140), the big hit game process (step S150), and the magnetic sensor monitoring process (step S160) are repeatedly executed. In the present embodiment, the time required for the processes of steps S110 to S160 is about 4 msec, and therefore these processes are repeatedly executed at intervals of about 4 msec. The main control board 70 advances the entire game of the pachinko machine 10 by transmitting various commands to the control board in charge and executing the processes according to the commands in accordance with the execution of these processes.

[Game start processing]
In the game start process of step S110, the CPU 70a of the main control board 70 first detects the state of various sensors (gate switch 32a, start port switch 36a, big prize port switch 45a, count switch 45b, magnetic sensor 50, etc.). Are stored in a predetermined state storage area of the RAM 70c, and various random values (such as jackpot determination random numbers, jackpot symbol determination random numbers, reach random numbers, variation pattern determination random numbers, which will be described later) are updated. Subsequently, it is determined whether or not a switch relating to winning of a game ball (such as a start opening switch 36a or a large winning opening switch 45a) is detected, and if it is determined that it has been detected, the number of winning balls to be paid out is calculated. The prize ball information is stored in a predetermined prize ball information storage area of the RAM 70c. When the prize ball information is not 0, a prize ball number designation command (prize ball information) is transmitted to the payout control board 80, and the game start process is terminated. To do. When the payout control board 80 receives the award ball number designation command, the payout motor 86 is driven to pay out the game balls one by one, and the game balls paid out by the pre-payout switch 84 and the post-payout switch 85 are detected. Each time a prize ball payout process is performed to decrement the prize ball information (the number of unpaid game balls) by one value. This award ball payout process is repeatedly executed until the award ball information reaches a value of 0, but when a winning game ball is detected and a new award ball number designation command is received from the main control board 70, the award ball information is received. The process is repeated until the value becomes zero. When the game start process ends, the process returns to the main control process and proceeds to the normal symbol game process of the next step S120.

[Normal design game processing]
In the normal symbol game process of step S120, the CPU 70a of the main control board 70 first determines whether or not the normal symbol hold is not the value 0, that is, whether the value is 1 or more. The normal symbol is determined to be decremented by 1, and the normal symbol to be stopped and displayed is determined based on the result of the determination. That is, when the determination result is a win, it is determined that the symbol (see FIG. 6 (d)) is to be stopped and displayed. When the determination result is not correct, the winning symbol (FIG. 6 (a) to FIG. 6) is determined. (See (c)) is determined as a symbol to be stopped and displayed. Then, the normal symbol fluctuation display time is set to start the normal symbol fluctuation display, and waits until the fluctuation display time elapses. The variable display time is set to a long time (for example, 30 seconds) when not in the short time state, and is shortened to a short time (for example, 1 second) when in the short time state. When the variable display time elapses, the normal symbol is stopped and displayed with the determined symbol, and when the stopped and displayed symbol is the winning symbol, the opening time of the ordinary electric accessory 38 is set, and the ordinary electric accessory 38 is opened. The normal symbol game process is temporarily terminated, and when the stopped and displayed symbol is out of the symbol, the normal symbol game process is terminated without doing anything. The opening time of the ordinary electric accessory 38 is set to a short time (for example, 0.5 seconds) when not in the short time state, and is extended to a long time (for example, 5 seconds) when in the short time state. Further, as described above, the ordinary electric accessory 38 is opened by controlling the drive of the ordinary electric accessory solenoid 39 to open the pair of blade pieces 38a, 38b to the left and right. When the normal symbol game process ends, the process returns to the main control process and proceeds to the next normal symbol game process in step S130.

[Game processing per normal symbol]
In the normal symbol game process in step S130, the CPU 70a of the main control board 70 sets the elapsed time (open elapsed time) from the start of the normal electric accessory 38 to the set time set in the normal symbol game process. It is determined whether or not a predetermined number (e.g., 8) of game balls has won the start opening 36. If it is determined that the elapsed time has not reached the set time and a specified number of game balls have not won the start opening 36, the game processing per normal symbol is temporarily performed while the normal electric accessory 38 is kept open. finish. On the other hand, if it is determined that the elapsed elapsed time has reached the set time, or if it is determined that a prescribed number of game balls have already won the start opening 36 even before the elapsed elapsed time has reached the set time. Then, the driving of the ordinary electric accessory 38 is stopped, and the game process per ordinary symbol is finished. When the normal symbol per game process is completed, the process returns to the main control process and proceeds to the special symbol game process of the next step S140.

[Special design game processing]
The special symbol game process of step S140 is executed according to the flowcharts shown in FIG. 14 (first half part) and FIG. 15 (second half part). When the special symbol game process of FIGS. 14 and 15 is executed, the CPU 70a of the main control board 70 first inputs a detection signal from the start port switch 36a to determine whether or not a game ball has won the start port 36. Is determined (step S200). If it is determined that the game ball has won the start opening 36, it is determined whether or not the current number of holds is less than the upper limit value (value 4 in this embodiment) (step S202). When it is determined that the current number of holds is less than the upper limit value, the number of holds is incremented by 1 (step S204), and a determination random number is acquired and stored in a predetermined determination random number storage area of the RAM 70c ( Step S206). When the number of holdings is incremented by the processing of step S204, a command (holding number designation command) for displaying the number of holdings on the special symbol holding lamp 35a provided in the display screen of the effect display device 34 is displayed on the sub-control board 90. Send. Further, as the determination random number acquired in step S206, the big hit determination random number used in the big hit determination performed by winning the game ball to the start port 36, or the special symbol when the result of the big hit determination is the big hit Whether or not to perform reach display when effect symbols are variably displayed on the display screen of the effect display device 34 when the result of the jackpot determination is out of order and the result of determining the jackpot symbol for determining the jackpot symbol to be stopped and displayed on the display device 42 Reach random number for determining the value. If it is determined in step S200 that no game ball has been won at the start opening 36, or if it is determined that the number of holds has reached the upper limit, the processing in steps S204 and S206 is skipped and the next processing is performed. move on.

  Next, it is determined whether or not a big hit game is being played (step S208), whether or not a special symbol variation is being displayed (step S210), whether or not it is during a stop display time (step S212), and the number of holds is 0. Whether or not (step S214). If it is determined that a big hit game is being played, the special symbol game process is terminated, and the process returns to the main control process to proceed to the next big hit game process in step S150. On the other hand, if it is determined that the game is not a big hit game, the special symbol variation display is not being performed, the stop display time is not being displayed, and the number of reservations is not 0, the number of reservations is decremented by 1 (step S216). The oldest determination random number (big hit determination random number) among the determination random numbers stored in the storage area is read (step S218). Then, the jackpot determination is performed using the jackpot determination table and the read jackpot determination random number (step S220), the symbol variation start process shown in FIG. 17 is executed (step S222), and the special symbol game process is temporarily ended. . Here, in the jackpot determination table, a jackpot determination table for the low probability mode illustrated in FIG. 16A and a jackpot determination table for the high probability mode illustrated in FIG. 16B are prepared. When the current gaming state is the normal mode (low probability mode), the jackpot determination is performed using the table for the low probability mode, and when the current gaming state is the probability variation mode (high probability mode), the table for the high probability mode. The big hit is judged using. Details of the symbol variation start process in FIG. 17 will be described below.

  In the symbol variation start process of FIG. 17, the CPU 70a of the main control board 70 determines in which state the current gaming state is, that is, a gaming state that is in the low probability mode and not in the short time state (low probability non-short time state). It is determined whether the game state is in a low probability mode and in a short time state (low probability short time state) or in a high probability mode (high probability state) (step S300). This determination can be made by examining the value of a probability variation flag or a variation shortening flag, which will be described later. Subsequently, it is determined whether or not the result of the big hit determination is a big hit (step S302). If the big hit is determined, a big hit variation pattern table is set (step S304). Here, the variation pattern table for jackpot is associated with a variation pattern determining random number, a variation pattern, and a variation time, and is set for each gaming state in accordance with the gaming state determined in step S300. FIG. 18 shows an example of a jackpot variation pattern table in the low probability mode, and FIG. 19 shows an example of a jackpot variation pattern table in the high probability mode. 18 and 19 show a table storing a small number of patterns for the sake of convenience, but actually, a table storing a larger number of patterns (for example, 20 or more patterns) is used. As shown in the drawing, when the low probability non-short-time state is in the low-probability non-time short-time big hit variation pattern table shown in FIG. 18A, the low-probability short-time fluctuation pattern table shown in FIG. 18B is set. Set the fluctuation pattern table for hourly and big hits. Further, when in the high probability state, the high probability big hit variation pattern table shown in FIG. 19 is set. The low-probability non-short-time big hit variation pattern table includes a variation pattern (pattern 3) for performing a freeze effect (stagnation effect) according to the present invention (see FIG. 18A).

  When the jackpot variation pattern table is set, a variation pattern determining random number is acquired (step S306), the jackpot symbol determining random number is read (step S308), the set jackpot variation pattern table, the acquired variation pattern determining random number, Is used to set the big hit symbol variation pattern, and the big hit symbol to be stopped and displayed is set using the read big hit symbol determining random number (step S310). FIG. 20 shows an example of the jackpot symbol determination table. In this embodiment, as shown in FIG. 20, the big winning symbol is “first normal big winning” when the random symbol for determining the big winning symbol is 0 to 101 and the stop symbol of FIG. (About 40% big hit distribution probability), when the big hit symbol determination random number is between the value 102 and the value 203, the stop symbol of FIG. 7B is selected and becomes the “first probable big hit” (about 40% big hit) Distribution probability). Further, when the big hit symbol determining random number is between the value 204 and the value 255, the stop symbol of FIG. 7C is selected and becomes the “second probability variation big hit” (approximately 20% big hit distribution probability).

  If it is determined in step S302 that the result of the big hit determination is not a big hit, it is further determined whether or not reach display is performed using a random number for reach (step S312). A table is set (step S314), and when reach display is not performed, a non-reach variation pattern table is set (step S316). Here, the variation pattern table for losing (including the presence or absence of reach) is associated with the variation pattern determination random number, the variation pattern, and the variation time in the same manner as the big hit variation pattern table, and is determined in step S300. It is set for each gaming state according to the gaming state, and is further set for each special symbol hold number when the gaming state is not in the short-time state. FIG. 21 shows an example of a deviation variation pattern table for the low probability mode, and FIG. 22 shows an example of a deviation variation pattern table for the high probability mode. 21 and FIG. 22 collectively show the unreachable variation pattern table and the reachable variation pattern table. 21 and 22 show a table storing a small number of patterns for the sake of convenience, but actually a table storing a larger number of patterns (for example, 20 or more patterns) is used. As shown in the figure, the deviation variation pattern table is set when the low probability non-short-time state is set, as shown in FIG. 21 (a). a) The upper stage low fluctuation pattern table for low probability non-time short reach is set, and if there is a reach, the lower stage low probability non-time short reach reach fluctuation pattern table in FIG. When in the short-time state, the low-probability short-time deviation variation pattern table shown in FIG. 21B is set (if there is no reach, the low-probability short-time non-reach fluctuation pattern table in FIG. 21B is set. If there is a reach, the low probability short-time reach-with-reach variation pattern table in the lower part of FIG. Further, when there is a high probability state, the fluctuation pattern table for outbreak at high probability shown in FIG. 22 is set (when there is no reach, the fluctuation pattern table for outbreak without reach at high probability shown in FIG. (Set the variation pattern table for detachment with high probability in the lower part of FIG. 22). The low probability non-short-time deviation variation pattern table includes a variation pattern (pattern 18) for performing a freeze effect (see FIG. 21A). In this embodiment, the appearance probability of the freeze effect in the out-of-flight symbol variation pattern is set relatively low compared to the appearance probability of the freeze effect in the jackpot symbol variation pattern, and is accompanied by a reach display in the normal mode (low probability mode). When the freeze effect appears, it is adjusted to be a big hit with a relatively high probability.

  When the deviation variation pattern table is set, a variation pattern determination random number is acquired (step S318), and the deviation symbol variation pattern is set and removed using the set variation pattern determination random number and the acquired variation pattern determination random number. A symbol is set (step S320). Although the detailed explanation is omitted, for example, the winning symbol can be set using a jackpot symbol determining random number and a not-showing symbol determining table. Of course, if a losing symbol determining random number is acquired separately from the jackpot symbol determining random number, it can be set using the losing symbol determining random number and the losing symbol determining table.

  When the big hit symbol variation pattern and the big hit symbol or the out symbol design variation pattern and the out symbol design are set, the special symbol variation display is started (step S322), and the symbol variation start command is transmitted to the sub control board 90 (step S322). S324), the symbol variation start process is terminated. Here, the symbol variation start command includes a big hit symbol variation pattern, a variation time in the pattern (variation pattern designation command) and a big hit stop symbol (special symbol stop information designation command) in the case of a big hit, The out symbol change pattern, the change time in the pattern (variation pattern designation command) and the out stop symbol (special symbol stop information designation command) are included. In addition, the symbol change start command includes the number of special symbols held (holding number designation command). Receiving the symbol variation start command, the sub-control board 90 analyzes the command, determines the effect content to be performed on the screen of the effect display device 34, and controls the effect display device 34.

  Hereinafter, the effect process by the sub-control board 90 will be described. FIG. 23 is a flowchart showing an example of the symbol variation effect process executed by the CPU 90a of the sub-control board 90. When the symbol variation effect process of FIG. 23 is executed, the CPU 90a of the sub control board 90 first determines whether or not the symbol variation start command described above has been received (step S600). When the symbol variation start command is not received, the process proceeds to the next step S612. On the other hand, when the symbol variation start command is received, the received symbol variation start command is analyzed to determine whether or not it is a big hit (step S602). When it is determined to be a big hit, a big hit effect pattern is selected and set as an effect pattern on the effect display device 34 (step S604). This is set (step S606). Here, the effect pattern on the effect display device 34 is selected so as to correspond to the variation pattern (and variation time) of the special symbol, and the variation pattern of the special symbol corresponds to the freeze effect ( In this embodiment, if the variation pattern of the special symbol is the pattern 3 shown in FIG. 18 (a) or the pattern 18 shown in FIG. 21 (a), an effect pattern incorporating a freeze effect of the effect symbol is selected. Here, the freezing effect of the effect symbol is an effect that temporarily stops the variable display of the effect symbol in the middle (before reaching the fluctuation time) and then resumes the variable display, and the progress of the game is in progress This is an effect to give the player the impression of stopping.

  When the effect pattern is set in this way, the stop symbol of the effect symbol is set based on the stop symbol of the special symbol (step S608), and the symbol variation effect is started (step S610). The symbol variation effect is performed by the CPU 90 a of the sub control board 90 outputting various display control commands to the effect display control board 91. The effect display control board 91 that has received the various display control commands controls the operation of the effect display device 34 based on the received commands. Thereby, the variable display of the three effect symbols 34L, 34M, and 34R is started. In addition, the CPU 90a of the sub control board 90 outputs a drive signal to the amplifier board 92 so that sound is output from the various speakers 28a and 28b in accordance with the change display of the effect symbols, or various changes in accordance with the change display of the effect symbols. A drive signal is output to the decorative drive board 93 so that the LED lamp 93a is lit.

  When it is determined in step S600 that the symbol variation start command has not been received, or after the symbol variation effect is started in step S610, is the effect symbol being variably displayed in the effect pattern corresponding to the freeze effect? It is determined whether or not (step S612), and if a positive determination is made, a freeze effect process is executed (step S614). After making a negative determination in step S612 or executing the freeze effect process, it is determined whether or not a symbol stop command has been received (step S616), and when it is determined that a symbol stop command has not been received. If it is determined that the symbol variation effect process is finished and the symbol stop command is received, the symbol variation effect is terminated (step S618), and the symbol variation effect process is terminated.

  FIG. 24 is a flowchart illustrating an example of a freeze effect process executed by the CPU 90a of the sub control board 90. In the freeze effect process, the CPU 90a of the sub control board 90 first determines whether or not it is the freeze effect start timing (step S700). The freeze effect start timing can be known in advance as the elapsed time (freeze effect start time) from the effect start from the effect pattern selected in steps S604 and S606 of the symbol variation effect process. Therefore, the determination in step S700 can be made by determining whether or not the elapsed time from the start of the effect has reached the freeze effect start time corresponding to the selected effect pattern. If it is determined that it is the start timing of the freeze effect, the freeze effect is started (step S702), and the electromagnet is turned on (see FIG. 10B) to turn on the coil to generate magnetism from the electromagnet 52. A drive signal is output to the drive substrate 95 (step S704). In the processing of steps S702 and S704, the sound output from the various speakers 28a and 28b is stopped in accordance with the start timing (temporary stoppage of the effect design) of the effect design incorporated in the effect design being executed. As described above, the driving signal is output to the amplifier board 92 and the driving signal is output to the decorative driving board 93 so that the various LED lamps 93a are turned off. This is a process for forcibly stopping the launch of the game ball regardless of the operation. In this way, the freeze effect is an effect that realizes the temporary change stop of the effect symbol, the stop of the various speakers 28a and 28b and the various LED lamps 93a, and the forced stop of the game ball firing substantially simultaneously. In this way, the player's interest is strongly attracted. If it is determined in step S700 that it is not the freeze effect start timing, the processing in steps S702 and S704 is skipped.

  After it is determined in step S700 that it is not the freeze effect start timing, or after the permanent magnet 52 has been moved to the detectable position of the magnetic sensor 50 in step S704, it is determined whether it is the freeze effect end timing (step S706). ). The freeze effect end timing can be known in advance as the elapsed time from the start of the effect (freeze effect end time) from the selected effect pattern, similarly to the freeze effect start timing. Therefore, the determination in step S706 can be made by determining whether or not the freeze effect end time corresponding to the selected effect pattern has elapsed since the start of the effect. If it is determined that it is not the freeze effect end timing, the freeze effect process is once ended. If it is determined that it is the freeze effect end timing, the freeze effect is ended (step S708), and magnetism is lost from the electromagnet 52. A drive signal is output to the electromagnet drive board 95 so that energization to the coil is turned off (see FIG. 10A) (step S710), and the freeze effect process is terminated. In the processes of steps S708 and S710, audio is output from the various speakers 28a and 28b in accordance with the end of the freeze effect of the effect symbol incorporated in the effect pattern that is being executed (in response to the restart of the variation of the effect symbol that has been paused). The driving signal is outputted to the amplifier board 92 and the driving signal is outputted to the decorative driving board 93 so that the various LED lamps 93a are lit, so that the magnetism of the electromagnet 52 is not detected by the magnetic sensor 50 and the game ball is launched. Is a process of restarting.

  FIG. 25 shows a state of variation display of the effect symbol accompanied by the freeze effect. As shown in the figure, the freezing effect of the effect symbol is scrolled while maintaining the semi-transparent state from the state where the three symbols 34L, 34M, and 34R are scrolling in a semi-transparent state (see FIG. 25A). This is done by stopping the fluctuation (see FIG. 25B). When the freeze effect ends, the three symbols 34L, 34M, and 34R resume scrolling variation while being in a semi-transparent state (see FIG. 25C). Then, the scroll variation is stopped in the order of the left symbol 34L, the right symbol 34R, and the middle symbol 34M, and the symbols for which the scroll variation has been stopped are clearly visible without being translucent (FIGS. 25D to 25D). f)). In this way, the effect design that is temporarily stopped with the freeze effect and the effect design that is stopped after the variable display time has elapsed are the state where the former is translucent and the latter is not translucent. Therefore, the two can be clearly distinguished, and the player can be strongly impressed that the freeze effect is a special effect. The symbol variation effect process and the freeze effect process by the sub control board 90 have been described above.

  Returning to the special symbol game process of FIG. 14 and FIG. 15, after the special symbol variation display is started, when the special symbol game processing is executed next, it is determined in step S210 that the special symbol is being varied. Therefore, the CPU 70a of the main control board 70 determines whether or not the variable display time (variable time) has elapsed (step S224). Since the fluctuation display time is determined according to the fluctuation pattern when the fluctuation pattern of the special symbol is determined, whether or not the fluctuation display time has passed is determined by the elapsed time from the start of the fluctuation display of the special symbol. This can be done by comparing the determined variable display time. If it is determined that the variable display time has not elapsed, the special symbol game process is temporarily terminated. If it is determined that the variation display time has elapsed, the variation of the special symbol is stopped (step S226), and a symbol stop command is transmitted to the sub-control board 90 (step S228). The sub control board 90 that has received the symbol stop command transfers the symbol stop command to the effect display control board 91. Then, a stop display time is set (step S230), and it is determined whether or not the stop display time has elapsed (step S232). Here, the stop display time is an interval from when the special symbol variation display is stopped until the next variation display is started, and is set to 0.6 seconds, for example. If it is determined that the stop display time has not elapsed, the special symbol game process is temporarily terminated. When the special symbol is stopped and displayed, it is determined in step S212 that the stop display time is being reached. Therefore, in step S232, it is determined again whether or not the stop display time has elapsed, and it is determined that the stop display time has elapsed. Then, it is determined whether or not the special symbol that is stopped and displayed is a jackpot symbol (step S234).

  If it is determined in step S234 that the game is a big hit symbol, the big hit game flag is turned on (step S236). Thereby, the big hit game is started by the big hit game processing described later. In addition, during the big hit game, in order to temporarily stop the probability variation function, the time shortening function, and the release extension function, the probability variation flag is turned off when the probability variation flag is on (steps S238 and S240), and the variation shortening is performed when the variation shortening flag is on. The flag is turned off and the release extension flag is turned off (steps S242 to S246), the special symbol game process is terminated, and the process returns to the main control process to proceed to the next step S150 big hit game process.

  On the other hand, if it is determined in step S234 that the symbol is not a big hit symbol, it is determined whether or not the variation shortening flag is on (step S248). If the variation shortening flag is not on, the special symbol game process is temporarily terminated. When the fluctuation shortening flag is ON, the fluctuation shortening counter is decremented by 1 (step S250), and it is determined whether or not the fluctuation shortening counter is 0 (step S252). Here, the fluctuation shortening counter indicates the upper limit value of the number of fluctuations of the special symbol that maintains the short time (ordinary symbol fluctuation shortening) state, and a value corresponding to the big hit mode is set after the big hit. When the fluctuation shortening counter is not 0, the special symbol game process is temporarily terminated while maintaining the time shortening state. When the fluctuation shortening counter is 0, the variation shortening flag is turned off in order to terminate the time shortening state ( In step S254), the release extension flag is turned off (step S256), a game state designation command is transmitted to the sub-control board 90 (step S258), and the special symbol game process is temporarily terminated. Thereby, the gaming state of the pachinko machine 10 is changed from the short-time state to the non-short-time state. Note that the gaming state designation command includes a variation shortening flag and an opening extension flag indicating the current gaming state of the pachinko machine 10. The sub control board 90 that has received the gaming state designation command outputs a control signal to the effect display control board 91 to change the background screen of the effect display device 34 from the background for the time reduction to the background for the non-time reduction, for example. Perform processing. The determination in step S252 is executed regardless of whether the mode is the normal mode or the probability variation mode. However, in the first probability variation big hit or the second probability variation big hit, 10,000 times are set in the fluctuation shortening counter after the big hit. Therefore, in the case of these probable big hits, the fluctuation shortening counter cannot normally have a value of 0, and the time saving state does not end until the next big hit is drawn.

[Big hit game processing]
The big hit game process of step S150 is executed according to the flowchart shown in FIG. When the jackpot game process of FIG. 23 is executed, the CPU 70a of the main control board 70 first determines whether or not the jackpot game flag is on, that is, whether or not the jackpot game is in progress (step 400). If it is determined that the big hit game is not being played, the big hit game processing is terminated as it is. When the big hit game process ends, the process returns to the main control process and proceeds to the next magnetic sensor monitoring process in step 160. On the other hand, if it is determined that the big hit game is being played, it is determined whether or not the big winning opening 44 is being opened (step S402). Considering immediately after the big hit occurs, since the big winning opening 44 is closed, a negative determination is made in step S402, and then it is determined whether or not the big hit game end condition is satisfied ( Step S404). This determination is performed by determining whether or not the number of repetitions (number of rounds) of the opening operation of the big winning opening 44 has reached a predetermined number determined according to the big hit mode. In this embodiment, if the big hit mode is the first normal big hit or the first probability variable big hit, whether or not the number of rounds has reached 15 times, and if the big hit mode is the second probability variable big hit, the number of rounds is two. It is determined whether or not it has been reached. Immediately after the big hit has occurred, it is determined in step S404 that the big hit game end condition is not satisfied. Next, it is determined whether or not the specified closing time (2 seconds in this embodiment) has elapsed. (Step S406) When it is determined that the specified closing time has elapsed, the big prize opening solenoid 44a is driven and controlled so that the big prize opening 44 is opened (Step S408), and the big hit game process is once ended.

  When opening of the big winning opening 44 is started, it is determined in step S404 that the big winning opening 44 is being opened when the big hit game process is executed next. Whether or not the time has reached a predetermined opening time (step S410), and whether or not the number of game balls won in the special winning opening 44 has reached a specified number (10 in this embodiment) (step S412). Determine. Here, the opening time is determined according to the big hit mode, and in this embodiment, it is 25 seconds when either the first normal big hit or the first positive probability big hit, and the second positive change. It is 6 seconds for a big hit. When the elapsed time from the opening of the grand prize winning opening 44 has not reached the predetermined opening time and the number of game balls won to the big winning prize opening 44 has not reached the prescribed number, The jackpot game process is temporarily ended while maintaining the opening. On the other hand, when it is determined that the elapsed time from the opening of the grand prize opening 44 has reached a predetermined opening time, or even if the game ball that has won the grand prize opening 44 has not reached the opening time, When it is determined that the number has reached the specified number, the big prize opening solenoid 44a is driven and controlled so that the big prize opening 44 is closed (step S414), and the big hit game process is once ended. If the big winning opening 44 is closed, it is determined in step S402 that the big winning opening 44 is not open when the big winning game processing is executed next. The special winning opening 44 is opened until the closing time elapses (steps S404 to S408). Thus, the big hit game is advanced by repeating the opening operation of the big winning opening 44 while sandwiching the closed state. When the number of repetitions of the opening operation of the big winning opening 44 reaches the specified number, it is determined in step S404 that the big hit game end condition is satisfied, and the big hit game end process illustrated in FIG. 27 is executed (step S416). The jackpot game process is terminated.

  In the big hit game end process of FIG. 27, first, the CPU 70a of the main control board 70 turns off the big hit game flag from ON to OFF (step S450), whether the big hit symbol is a probability variation symbol, that is, whether the current big hit is the first probability variation big hit. It is determined whether it is one of the second probability variation big hits (step S452). If it is determined that it is not a probability variation symbol, that is, the current big hit is the first normal big hit, the probability variation flag is kept off and the fluctuation shortening counter is set to 100 times (step S454), and the probability variation symbol is judged. Then, the probability variation flag is turned on (step S456), and the fluctuation shortening counter is set to 10,000 times (step S458). As described above, when the fluctuation shortening counter is set 10,000 times, the time-saving state is substantially continued until the next big hit is drawn. When the fluctuation shortening counter is set in this way, the fluctuation shortening flag is turned on (step S460), the release extension flag is turned on (step S462), and a gaming state designation command is transmitted to the sub control board 90 (step S462). The process when the big hit game ends is completed. The sub control board 90 that has received the game state designation command performs processing such as, for example, outputting a control signal to the effect display control board 91 to set the background screen of the effect display device 34 as the background for the time reduction.

[Magnetic sensor monitoring processing]
The magnetic sensor monitoring process in step S160 is executed according to the flowchart illustrated in FIG. When the magnetic sensor monitoring process of FIG. 28 is executed, the CPU 70a of the main control board 70 determines whether or not the magnetic sensor 50 is turned on, that is, the detection signal from the magnetic sensor 50 does not detect magnetism. It is determined whether or not the state has changed to a state in which magnetism is detected (step S500). When the magnetic sensor 50 is not turned on from OFF, the process proceeds to the next step S512. On the other hand, when the magnetic sensor 50 is switched from OFF to ON, the firing stop process is executed so that the game ball is stopped regardless of the operation of the launch handle 18 (step S502). As described above, the firing stop process is performed by transmitting a firing stop signal from the main control board 70 to the launch control board 100 (the launch control unit 106) via the payout control board 80. Subsequently, whether or not the special symbol is in a variable display (step S504), whether or not the special symbol variation pattern corresponds to the freeze effect (in this embodiment, the special symbol variation pattern is shown in FIG. ) Or the pattern 18 shown in FIG. 21A) is determined (step S506). If it is determined that the special symbol is not in a variable display, or if it is determined that the special pattern does not correspond to the freeze effect even if the special symbol is in a variable display, the player performs an illegal act using a magnet. The abnormality occurrence flag is turned on (step S508), and an abnormality occurrence notification start command is transmitted to the sub control board 90 (step S510). The sub-control board 90 that has received the abnormality occurrence notification start command executes a predetermined abnormality occurrence notification process. Details of the abnormality occurrence notification process will be described later. On the other hand, when it is determined that the special symbol is variably displayed and the variation pattern corresponds to the freeze effect, the magnetism of the electromagnet 52 is intentionally detected by the magnetic sensor 50 for the freeze effect. And the processing of steps S508 and S510 is skipped.

  Then, it is determined whether or not the magnetic sensor 50 has been turned off from on, that is, whether or not the detection signal from the magnetic sensor 50 has changed from a state of detecting magnetism to a state of not detecting magnetism ( Step S512). If it is determined that the magnetic sensor 50 has not been turned off from on, the magnetic sensor monitoring process is temporarily terminated, the process returns to the main control process, and the process returns to step S110 again. On the other hand, if it is determined that the magnetic sensor 50 has been turned off from on, a firing stop cancellation process is executed (step S514). The firing stop canceling process is performed by transmitting a canceling signal for canceling the firing stop from the main control board 70 to the launch control board 100 (the launch control unit 106) via the payout control board 80. Then, it is determined whether or not the abnormality occurrence flag is on (step S516). When it is determined that the abnormality occurrence flag is off, it is determined that the freeze effect has ended, and the magnetic sensor monitoring process is ended as it is, and the abnormality occurrence flag is determined. Is determined to be on, it is determined that fraudulent acts by the magnet are no longer detected, the abnormality flag is turned off (step S518), and an abnormality notification notification end command is transmitted to the sub-control board 90 (step S520). ), The magnetic sensor monitoring process is terminated.

  Next, the abnormality occurrence notification process will be described. FIG. 29 is a flowchart showing an example of an abnormality occurrence notification process executed by the CPU 90a of the sub-control board 90. When the abnormality occurrence notification process of FIG. 29 is executed, the CPU 90a of the sub control board 90 first determines whether or not an abnormality occurrence notification start command has been received (step S800), and has received the abnormality occurrence notification start command. Sometimes the abnormality occurrence notification effect is started (step S802). Here, in the abnormality occurrence notification effect, a control signal is output to the effect display control board 91 so that a warning such as “error occurrence” is displayed on the display screen of the effect display device 34, or a buzzer sound is output from the various speakers 28a and 28b. A driving signal is output to the amplifier board 92 so that a warning sound such as the above is emitted, and the decorative driving board 93 is driven so that various LED lamps 93a are lit in a warning lighting mode (for example, a mode in which the LED lamp 93a is kept lit). This is done by outputting a signal. In addition, abnormality notification to a hall computer (not shown) may be performed. Of course, some of these processes may be omitted. Then, after starting the abnormality occurrence notification effect or when it is determined in step S800 that the abnormality occurrence notification start command has not been received, it is determined whether an abnormality occurrence notification end command has been received (step S804). When it is determined that the abnormality occurrence notification end command has not been received, the abnormality occurrence notification processing is temporarily terminated as it is, and when it is determined that the abnormality occurrence notification end command has been received, the abnormality occurrence notification effect is ended (step S806). Then, the abnormality occurrence notification process is terminated.

  According to the pachinko machine 10 of the embodiment described above, in the pachinko machine including the magnetic sensor 50 for detecting fraud, the electromagnet 52 is arranged in the detection area of the magnetic sensor 54, and at the time of freeze production, Since energization of the coil of the electromagnet 52 is turned on and the magnetic sensor 50 intentionally detects the magnetism of the electromagnet 52 to forcibly stop the game ball from being emitted, the magnetic sensor 50 is effectively used for the game. be able to. Moreover, in the case of the freeze effect, the effect display variation display of the effect display device 34 is temporarily stopped in the middle, and the freeze effect is temporarily stopped for the effect symbol change display and the forced stop of the game ball firing. Can be realized almost simultaneously, so that the player's interest can be strongly attracted and the interest can be improved. In addition, production symbols that are temporarily stopped with a freeze production are expressed translucently, and those that are stopped after the variable display time has elapsed are expressed in a clearly visible state that is not translucent. Can be clearly distinguished, and the player can be strongly impressed that the freeze effect is a special effect. Further, when magnetism is detected by the magnetic sensor 50, the abnormality occurrence notification process is executed when the freeze effect is not being performed, and the abnormality occurrence notification process is skipped when the freeze effect is being performed. Can be executed.

  In the pachinko machine 10 according to the embodiment, the freeze effect is accompanied by the reach effect. However, the present invention is not limited to this. For example, the determination random number (the big hit determination random number) in the hold is prefetched and prefetched. In a gaming machine equipped with a so-called hold prefetching function that performs various effects (such as a notice effect) reflecting the prefetching results prior to the hold, a freeze effect may be used as an effect by the hold prefetching function. In this case, the jackpot determination is performed on the jackpot determination random number acquired in step S206 of the special symbol game process of FIG. 14, and a command indicating the determination result (pending prefetch result command) is held by the process of step S204. What is necessary is just to transmit to the sub control board 90 with the hold number designation | designated command which shows a number.

  In the pachinko machine 10 of the embodiment, as the freeze effect of the effect symbol, the effect symbol in the variable display is paused on the way, but is not limited to this, for example, the screen of the effect display device 34 is turned off, An effect that hides the variation display of the effect symbol is executed as a freeze effect of the effect symbol, such as a shutter-type movable decoration device that covers the entire screen of the effect display device 34 is provided and the shutter is closed at the time of the freeze effect. It may be a thing.

  In the pachinko machine 10 of the embodiment, as shown in FIG. 25 (b), as the freeze effect of the effect symbol, the effect symbol in the variable display is temporarily stopped and displayed in a semi-transparent state, accompanied by the freeze effect. The effect symbol that has been paused and the effect symbol that has been stopped and displayed after the lapse of the variable display time are distinguished from each other. However, as long as the two can be distinguished from each other, it may be paused in any stop mode. For example, as shown in FIG. 30, the arrangement of the three symbols 34L, 34M, and 34R in the horizontal direction may be temporarily stopped in a state in which they are shifted in the vertical direction.

  In the pachinko machine 10 according to the embodiment, the effect design paused with the freeze effect and the effect design stopped and displayed after the variable display time has elapsed are temporarily stopped. It is good also as what pauses in the mode which cannot be performed. In this case, it is desirable to separately provide a function (notification function) for notifying the player that the freeze effect is being performed. For example, the effect display device 34 may be provided with a small symbol that is linked to the effect symbol, and the player may be informed that the effect is a freeze effect such that the effect symbol is temporarily stopped but the small symbol is continuously displayed.
