PROBLEM TO BE SOLVED: To provide a pinball game machine provided with a rotary body for transferring a game ball to a prize port, the movement of which is hard for a player to estimate. SOLUTION: The pinball game machine is provided with a selecting means 73 for performing selection of choosing rotation pattern data of 1 by a lottery using a random number from two or more kinds of rotation pattern data of different details stored in a storage means 72 and choosing at random by this selection, and a control execution means 71 controls an electric motor operation regulating device 8A based on the rotation pattern data selected by the selecting means 73, and the movement of the rotary body 19 is varied at random by the details of the rotation pattern data chosen one after another. Thereby, since the movement of the rotary body 19 is difficult to estimate for not only a rotating speed and a rotating direction but also timing of variation, the movement, which is difficult for the player to estimate, is given to the rotary body 19.
