PROBLEM TO BE SOLVED: To provide a pinball game machine capable of adjusting the execution period of a high probability game. SOLUTION: When patterns for the high probability game are displayed on a display screen, the high probability game wherein the probability of winning a big winning is higher than usual is performed after a big winning game. The number of pachinko balls which can be shot during the high probability game is predetermined, and the number of the pachinko balls shot to a game area is counted by a count part. When the pachinko ball enters a start winning port or when the patterns for the high probability game are displayed on the display screen during the high probability game, the residual number of shooting is increased. When the last one of the pachinko balls which can be shot during the high probability game is detected by a ball detection sensor, a timer is operated and counting of 5 seconds is executed. When the pachinko ball does not enter the start winning port and the patterns for the high probability game are not displayed on the display screen during the counting of 5 seconds, the high probability game is ended after the counting of 5 seconds.
