PROBLEM TO BE SOLVED: To provide a variable prize winning port device for a pachinko game machine which can avoid the occurring of a double prize winning. SOLUTION: An electromagnetic solenoid 21 is retracted by controll to make a control device able to prohibit the winning to the variable prize winning port device 20, and a sensor arranging part 20b retracts to a device body part 20a, and a forward protruding amount of a plurality of prize winning port parts 20f from the device body part 20a is reduced. Thus, all of the prize winning port parts 20f become unable to take in balls from a game region. Also, the control device can allow the winning to the variable prize winning port device 20, and the sensor arranging part 20b advances to the device body part 20a by advancing the electromagnetic solenoid 21 by control, and the forward protruding amount of a plurality of the prize winning port parts 20f from the device body part 20a is increased. Thus, all of the prize winning port parts 20f become able to take in balls from the game region, and at the same time, the taken in balls are discharged to the game region. COPYRIGHT: (C)2004,JPO
