PROBLEM TO BE SOLVED: To make the probability of flowing-into a hit port to be fair in a prize generator by providing a structure where the running passage of a received game ball is changed by a changing member. SOLUTION: A CPU reads a random number (S101), decides which one of an appearing body or a rotary body is an object to be controlled on the basis of the random number (S102) and activates a solenoid according to the object to be controlled or controls the rotary direction of a motor (S103). Since the appearing body or the rotary body is selected at random and controlled, the appearance timing of the appearing body or the change of a rotary direction in the rotary body is never predicted. Therefore, it is not predictable whether the game ball coming into a prize generator area from a flow-in port comes into contact with the appearing body or the rotary body or not, whether the ball passes a specified passage or not and which inclining direction is obtained in the passage. That is, the running passage of the game ball which comes into the generator area is not predicted.
