The basic circuit 61 is supplied with the following signals as input signals. First, the starting winning ball detectors 21a, 21b, and 21c are turned on as the pachinko balls start winning.
In response to this, a starting winning ball detection signal is input from the switch/sensor input circuit 71. When a pachinko ball enters the specific winning hole 6 (see FIG. 1), the specific winning ball detector 2 turns ON, and in response, a specific winning ball detection signal is sent from the switch/sensor input circuit 71 to the basic circuit 6.
given to 1. 10 pachinko balls in the variable winning ball device
If detected by the count detector 23, the 10 count detector 23 is turned on, and in response, a 10 count detection signal is applied from the switch/sensor input circuit 71 to the basic circuit 61. Each drum sensor 30a, 30b, 3
0c detects the non-reflective portions 31a, 31b, and 31c of each drum, and their detection signals are input from the switch/sensor input circuit 71 to the basic circuit 61.

The basic circuit 61 then provides control signals to the following circuits and devices. First, a sound generation control signal is applied to the speaker 7 via the sound circuit 80 . segment·

The program is executed once every sec. This basic circuit 61 has three types of random number generation counters: a random number 1 counter, a random number 2 counter, and a random number 3 counter. The random number 1 counter is a counter for determining success or failure, and is incremented by 1 each time the program is executed, and when the value reaches 222, for example, it starts counting up again from 0. When the pachinko ball starts winning, the value of this random 1 counter is picked up, and when the picked up value is, for example, "3", it is determined that the player has won the jackpot. The random 2 counter is a counter for determining the symbol to be displayed on the variable display device 14 when a jackpot is determined, and is incremented by 1 each time the program is executed, and when the value reaches 27, Count up again from 0. Then, the count value of the random 2 counter at the start of the variable display of the variable display device is picked up, and the display of the winning symbol is determined based on the picked up value. On the other hand, the random 3 counter is counted up using the reset waiting time after the control program is executed, and if it is not determined to be a jackpot based on the value of the random 1 counter, that is, it is a miss. This is for determining the display symbol for losing when the determination is made. In this way, there are 223 values of the random 1 counter from 0 to 222, and only the value "3" among them is a jackpot, so
The probability of winning the jackpot on the program is 1/223≒0.89
It becomes 6861/200. Also, the program probability is
The displayed probability is 1/223÷28/5832=5832/6244≒0
．． It becomes 934017.
