PROBLEM TO BE SOLVED: To provide a pachinko game machine which has a probability of a hit ball getting into a starting prize winning port regardless of nail adjustment. SOLUTION: This pachinko game machine is equipped with a variation prize winning device 20. When a ball gets into starting prize winning ports 9a-9c, a pair of opening/closing members 23a, 23b equipped on the variation prize winning device 20 are opened/closed. A hit ball getting into the variation prize winning device 20 gets into a V prize winning port 24 to get a jackpot. The central starting prize winning port 9a among the starting prize winning ports 9a-9c is made an electric starting prize winning port 9a. When a hit ball is detected by ball detectors 17a, 17b, a variation display 26 performs variation-displays based on the detection output. When a symbol at display stop of the variation display 26 matches a prescribed symbol, a tulip solenoid 16 is driven to open the electric starting prize winning port 9a. COPYRIGHT: (C)2004,JPO&NCIPI
