PROBLEM TO BE SOLVED: To provide a pachinko game machine which can solve a problem that even when a pachinko ball discharged into a game board just before a power failure enters a special pattern start port, a judgment action of a big hit is not made. SOLUTION: If a power failure takes place, a drive power source is applied to a special pattern start sensor 16 from a standby power source circuit, whereby the sensor 16 detects a pachinko ball, which is discharged to the upper part in a game board just before a shutoff of a main power source and enters a special pattern start port after the shutoff of the main power source. Moreover, the drive power source is applied to a main control device 20 from the standby power source, whereby the device 20 obtains a judgment information based on an output signal from the sensor 16. As a result, judgment action of a big hit is made based on judgment information just before the power failure when the power failure is restored, and hence the possibility that even if the pachinko ball discharged to the upper part in the game board just before the power failure enters the special pattern start port, a judgment action of a big hit is not made can be avoided.
