Each time the round of the jackpot game is completed, the meter needle 87A rotates to the MIN side, and when the minimum scale is pointed, the fact that the jackpot game is the final round is notified.

Next, the configuration of the control circuit unit that controls the operating state of the pachinko machine 1 configured as described above will be described in detail with reference to FIG.
As shown in FIG. 7, the control circuit unit 100 stores a CPU 101 for controlling the entire control circuit unit 100, an input port 106, a ROM 102 for storing a control program to be described later, various control processing data, and the like. RAM 103, an output port 108, and a reset circuit 105 that outputs a reset signal at a predetermined time interval (in this embodiment, about every 4 msec) are provided, and these are connected to each other by a bus 109. Yes. The CPU 101 is connected to a clock circuit 110 that outputs a clock signal.

The input port 106 is connected to the first start port switch 49A, the second start port switch 55A, the discharge port switch 74A, the gate switch 52A, the winning port switches 46A, 53A, 54A, 57A to 59A, and the like. .

The output port 108 is connected to a motor drive circuit 113 that drives and controls the medal motor 82 and the meter motor 88. The output port 108 is connected to a lamp driving circuit 114 for driving and controlling each full-color diode disposed on the front surface portion of the front cover member 4 and the prize ball payout device 22.

As shown in FIG. 7, the RAM 103 has a numerical value obtained by repeatedly adding 1 from 0 to 2 based on the clock signal input from the clock circuit 110 (the maximum value 2 is followed by the minimum value 0). A big hit counter 103A to be stored is provided. The count value of the jackpot counter 103A is read at the timing when the switch signal is input from the first start port switch 49A, and it is determined whether or not the jackpot is based on the read count value.
Here, for example, in normal times, the count value “1” corresponds to the jackpot, and in the case of a gaming state with probability variation (hereinafter referred to as “probability variation mode”), the count value “1, 2” is a jackpot. The other count values are out of range. Therefore, a jackpot is generated with a probability of 1/3 in the gaming state in the non-probability change mode, and a jackpot is generated with a probability of 2/3 in the probability variation mode.

The RAM 103 stores a numerical value obtained by repeatedly adding 1 from 0 to 999 based on the clock signal input from the clock circuit 110 (the maximum value 999 then returns to the minimum value 0). Is provided. The count value of the normal symbol counter 103B is read at the timing when the switch signal is input from the gate switch 52A, and it is determined whether or not it is a hit based on the read count value.
Here, for example, in normal times, the count value “1” corresponds to the win, and in the case of the so-called probability variation mode (when probability variation is acquired), the count values “1” to “999” correspond to the win. The other count values are out of range. Therefore, in the normal state, that is, in the gaming state in the non-probability change mode, the hit occurs with a probability of 1/1000, and in the probability variation dynamic mode, the hit occurs with a probability of 999/1000.
In addition, when the winning is lottery based on the count value of the normal symbol counter 103B, the normal symbol display device 62 is stopped and displayed at the normal symbol winning symbol after the fluctuation. That is, after the normal symbol display device 62 blinks alternately left and right, for example, the left LED is turned on and the right LED is turned off and stopped. In addition, when a loss is drawn by lottery based on the count value of the normal symbol counter 103B, the normal symbol display device 62 is stopped and displayed with the normal symbol lost symbol after the fluctuation. That is, after the normal symbol display device 62 blinks alternately left and right, for example, the left LED is turned off and the right LED is turned on and stopped.

  In addition, when “big hit” is drawn, as described later, after the three identification symbols of the special symbol display device 61 are changed, the symbols are stopped and displayed in a predetermined manner, that is, the big hit symbol (for example, , “---” to stop and display.) In addition, when “big hit” is drawn, when the pachinko ball passes through the discharge port 74, the effect medal 50 is rotationally driven, and the surface on which the “V” character is formed is stopped and displayed. Thereafter, as will be described later, a probability variation mode is entered. For example, when a pachinko ball passes through the gate 52, a “winning” is drawn with a probability of 999/1000 and the second start port 55 is opened, and this second start When winning a prize in the mouth 55, each special electric accessory 53, 54 is opened in turn. Further, the probability variation mode continues until the number of times that each special electric accessory 53, 54 is opened in order reaches a predetermined number (160 in this embodiment), and the second start port 55 is opened. The opening time of the second start port 55 becomes longer (for example, the second start port 55 is opened for a maximum of 6 seconds), and a lot of prize balls are paid out to the player (in other words, the player A so-called jackpot game).

The RAM 103 stores a numerical value obtained by repeatedly adding 1 from 0 to 7 based on the clock signal output from the clock circuit 110 (maximum value 7 and then returns to the minimum value 0). 103C is provided. The count value of the jackpot symbol selection counter 103C is read at the timing when the switch signal is input from the first start port switch 49A, and the special symbol display device 61 is changed and stopped after the fluctuation based on the read count value. The combination pattern of the jackpot symbol is specified.
For example, the count value “0” is a jackpot symbol “---”, the count value “1” is a jackpot symbol “1--”, the count value “2” is a jackpot symbol “--3”, and the count value “3” is Jackpot symbol “−4”, count value “4” is jackpot symbol “−5”, count value “5” is jackpot symbol “6--”, count value “6” is jackpot symbol “−7−”, The count value “7” corresponds to the jackpot symbol “−−8”. Each jackpot symbol is stored in advance in the ROM 102 corresponding to each count value of the jackpot symbol selection counter 103C. Each jackpot symbol is a symbol that is stopped and displayed after a series of symbol variations, as is well known.

In addition, the RAM 103 stores a numerical value obtained by repeatedly adding 1 from 0 to 200 based on the clock signal output from the clock circuit 110 (the maximum value 200 then returns to the minimum value 0). 103D is provided. The count value of the lost symbol selection counter 103D is read at the timing when the switch signal is input from the first start port switch 49A.
Further, the RAM 103 is provided with a parameter storage area 103E in which the count values of the counters 103A to 103D are stored.
The count values of the counters 103A to 103D and the parameter storage area 103E are initialized by substituting “0” at startup.

  Next, a game control process of the pachinko machine 1 configured as described above will be described with reference to FIGS. Here, the interrupt program of FIG. 8 operates every time a reset signal is input at regular intervals (for example, every 4 msec) after the power is turned on.

In S127, the CPU 101 stops displaying the fluctuation display of the normal symbol display device 62 through the display device control circuit 111 in a manner indicating a loss (for example, the CPU 101 turns off the LED on the left side of the normal symbol display device 62). Then, the right LED is turned on to stop the display.) The sub-process is terminated, the process returns to the main flowchart, and the process proceeds to S13.

On the other hand, when the hit determination flag read from the RAM 103 is ON, that is, when it is “1” (S126: YES), the CPU 101 proceeds to the process of S128.
In S <b> 128, the CPU 101 reads the hit determination flag from the RAM 103, turns off the hit determination flag, that is, substitutes “0” for the hit determination flag and stores it again in the RAM 103.
In S129, the CPU 101 stops and displays the variable display of the normal symbol display device 62 in a manner representing a win via the display device control circuit 111 (for example, the CPU 101 lights the left LED of the normal symbol display device 62). Then, the right LED is turned off and stopped.)
Subsequently, in S130, the CPU 101 reads the winning flag from the RAM 103, turns on the winning flag, that is, substitutes “1” for the big hit flag, stores the result again in the RAM 103, and ends the sub-process. Returning to the main flowchart, the process proceeds to S13.

Next, the sub-process of the “gate detection process” (S12) will be described with reference to FIG.
As shown in FIG. 14, first, in S141, the CPU 101 reads the normal symbol changing flag from the RAM 103 and turns on the normal symbol changing flag, that is, substitutes “1” for the normal symbol changing flag. Then, it is stored in the RAM 103 again. At the same time, the CPU 101 reads the count value of the normal symbol counter 103B and stores it in the parameter storage area 103E.

Subsequently, in S142, the CPU 101 reads the count value of the normal symbol counter 103B from the parameter storage area 103E, substitutes it into the normal hit algebra B, stores it in the RAM 103, and then determines whether or not the normal hit algebra B is “1”. A determination process for determining is executed.
When the pachinko machine 1 is activated, “0” is assigned to the ordinary hit algebra B and stored in the RAM 103.
If the normal algebra B is “1” (S142: YES), the CPU 101 proceeds to the process of S147.
On the other hand, when the normal algebra B is not “1” (S142: NO), the CPU 101 proceeds to the process of S143.
In S143, the CPU 101 reads out the time reduction flag from the RAM 103, and executes a determination process for determining whether or not the time reduction flag is ON, that is, whether it is “1”. When the time flag read from the RAM 103 is ON, that is, when it is “1” (S143: YES), the CPU 101 proceeds to the process of S145.

On the other hand, when the time flag read from the RAM 103 is OFF, that is, when it is “0” (S143: NO), the CPU 101 proceeds to the process of S144.
In S144, the CPU 101 reads the probability variation flag from the RAM 103, and executes a determination process for determining whether or not this probability variation flag is ON, that is, whether or not this probability variation flag is “1”.
When the probability variation flag is OFF, that is, when the probability variation flag is “0” (S144: NO), the CPU 101 proceeds to the process of S148. Therefore, when the probability variation flag is OFF, that is, in the normal gaming state, the lottery probability per normal symbol is 1/1000.

On the other hand, when the probability variation flag is ON, that is, when the probability variation flag is “1” (S144: YES), the CPU 101 proceeds to the process of S145.
In S145, the CPU 101 reads out the jackpot flag from the RAM 103, and executes a determination process for determining whether or not the jackpot flag is ON, that is, whether or not the jackpot flag is “1”.
If the jackpot flag is ON (S145: YES), the CPU 101 proceeds to the process of S148. Therefore, when the jackpot flag is ON, that is, when the jackpot game has not ended, the lottery probability for winning a normal symbol is 1/1000.

On the other hand, when the big hit flag is OFF (S145: NO), the CPU 101 proceeds to the process of S146.
In S <b> 146, the CPU 101 reads out the normal hit algebra B from the RAM 103 and executes a determination process for determining whether the normal hit algebra B is any one of “2” to “999”. When the ordinary algebra B read from the RAM 103 is not any of “2” to “999”, that is, when the ordinary algebra B is “0” (S146: NO), the CPU 101 performs S148. Move on to processing.

On the other hand, if the ordinary algebra B read from the RAM 103 is any one of “2” to “999” (S146: YES), the CPU 101 proceeds to the process of S147.
In S147, the CPU 101 determines that the winning is lottery, reads the winning determination flag from the RAM 103, turns on the winning determination flag, that is, substitutes “1” for the winning determination flag, and stores it again in the RAM 103. Therefore, when the probability change flag is ON or the time-short flag is ON and the jackpot flag is OFF, that is, in the game state of the probability change mode or the time-short mode, and when the jackpot game is not in progress, the lottery probability per normal symbol is 999/1000.
Subsequently, in S148, the CPU 101 starts the variable display of the normal symbol display device 62 via the display device control circuit 111, that is, after the normal symbol display device 62 starts blinking alternately on the left and right, and then executes the sub-process. The process returns to the main flowchart, and the process proceeds to S13.

  Here, the first start port 49 functions as a first start port. The first start port switch 49A functions as first detection means. The upper special electric accessory 53 and the lower special electric accessory 54 constitute a variable winning device and an ordinary electric accessory. The winning opening switch 53A and the winning opening switch 54A constitute second detecting means and fifth detecting means. The second start port 55 functions as a second start port. Further, the second start port switch 55A functions as third detection means. The gate 52 functions as a passing device. The gate switch 52A functions as a fourth detection unit. The CPU 101, the ROM 102, and the RAM 103 constitute a jackpot determination unit, a hit determination unit, a first control unit, a second control unit, a third control unit, and a fourth control unit. The ROM 102 and the RAM 103 constitute lottery probability storage means. The CPU 101 and RAM 103 constitute a number counter.

  As described above, according to the pachinko machine 1, when winning a prize at the first start port 49 and lottery is selected, the probability variation mode is set. Further, based on the pachinko ball passing of the gate 52 arranged in the right area of the game area 42, until the number of jackpot games in which each special electric accessory 53, 54 is released once reaches 160 times, 999 / A normal symbol win is drawn with a lottery probability of 1000 (S10, S12). When the normal symbol winning is selected, the second start port 55 arranged below each special electric accessory 53, 54 in the right area of the game area 42 is set for a long time (for example, about 6 seconds). It is opened and the pachinko ball is set in a state where it is easy to win (S8). Subsequently, when a jackpot is drawn based on winning at the second starting port 55, each special electric accessory 53, 54 arranged in the vertical direction of the right area of the game area is once in order from the top. It is set to be opened for a long time (for example, a maximum of about 30 seconds) (S1 to S6). Also, after the 160th jackpot game is over, it is set to the non-probability change mode, but it is set to the short-time mode only once, and the lottery for the first normal symbol is drawn with a probability of 999/1000. After that, it returns to the normal gaming state (S12).

  As a result, when a jackpot is lottery based on winning at the first starting port 49, the number of jackpot games in which each special electric accessory 53, 54 is opened for a long time one by one in order from the top is 160 times. Until the game area 42 is reached, the game is continued with a strong firing force so that the pachinko ball wins the gate 52, the second start port 55 and the special electric accessories 53, 54 arranged in the right area of the game area 42. Even so, the player can easily win the second starting port 55 without repeating fine adjustments of the launching device, and make it possible for the pachinko balls to easily win each special electric accessory 53, 54. Thus, it is possible to continuously enjoy games that are advantageous to the player.

In addition, when the jackpot is drawn based on the winning at the second starting port 55, the special electric accessories 53 and 54 arranged in the vertical direction of the right area of the game area 42 are opened in order from the top. Since the pachinko ball is set in a state where it is easy to win a prize, even if the player continues the game with a strong firing force, each special electric accessory 53, 54 and the second start opening 55 are repeatedly opened in order from the top. Thus, it is possible to show the player as if the pachinko ball is set in a state where it is easy to win a prize.
In addition, after the 160th big hit game is over, the first normal symbol winning lottery is drawn with a normal symbol winning probability of 999/1000, so the second start opening 55 is opened with high probability. Therefore, even if the player continues the game in a state where the shooting power is strong, there is a high possibility that the jackpot will be continuously acquired, and the player's interest can be strongly attracted.

  In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention. For example, the following may be used.

However, the second start port 55 is disposed below the gate 52, and this second start port Each special electric accessory 53, 54 may be arranged below 55. Further, when each special electric accessory 53, 54 is arranged below the second start opening 55, first, when a jackpot is drawn based on the winning to the second start opening 55, first, The drive control may be performed such that after the lower special electric combination 54 arranged below is opened once, the upper special electric combination 53 arranged on the upper side thereof is opened once.
Thereby, each special electric accessory 53, 54 and the second start opening 55 are repeatedly opened in order from the bottom, and it becomes possible to show the player as if the pachinko ball is set in a state where it is easy to win. .

  (B) In the above embodiment, in the probability variation mode, when the jackpot is drawn by winning the second starting port 55, each special electric accessory 53, 54 is sequentially opened once, Each special electric accessory 53, 54 may be configured to be opened twice in order. Further, in this case, when the number of jackpot games in which each special electric accessory 53, 54 is repeatedly opened twice in order from the top reaches 80 times, the non-probable variation mode is set. May be. Thereby, the player can acquire a lot of prize balls in a shorter time, and can further increase the interest of the game.
