PROBLEM TO BE SOLVED: To provide a pinball game machine capable of surely preventing a fraudulent action by nail bending cheating.SOLUTION: In the pinball game machine wherein a game ball which has entered a warp path 26 passes through the inside of a guide path 25 provided in a stage 17 and enters a start winning port 18 by a high probability, a discharge path 29 communicating with the back surface side of a game board 3 is provided inside the guide path 25, and a path switching valve 30 operated with an actuator 31 as a drive source is disposed at the branching point of the guide path 25 and the discharge path 29. When the number T1 per unit time of the game balls which enter the warp path 26 is below a reference value T0, the path switching valve 30 is withdrawn from the guide path 25 to allow the passing of the game balls. When the number T1 exceeds the reference value T0, by making the path switching valve 30 project into the guide path 25 and blocking the passing of the game balls, the game balls which have entered the warp path 26 are discharged to the back surface side of the game board 3 through the discharge path 29 in the middle of the guide path 25. |
