PROBLEM TO BE SOLVED: To provide a pinball game machine which can perform mechanical production using a game ball which does not participate in a target game for prize ball put-out, wherein a means is provided which enables an improvement in the execution frequency of ball production and ball production execution at the time of the occurrence of abnormality by grasping that a game ball concerning the ball production is in what kind of condition and can grasp that the abnormality is generated in which member even if sensors are not attached to all the mechanical members composing a ball production mechanism. SOLUTION: The pinball game machine includes a compartment condition presuming means, which presumes a compartment condition of a condition that a specific game ball is present within the compartment, a condition that it is not present, or an unknown condition by anticipating the presence of intrusion into the compartment and intrusion timing and discharge timing in case of intrusion about each of two or more compartments in which mechanical production is performed, and updates the presumed information with time when the mechanical production is performed after temporarily storing the presumed information by the compartment condition presuming means.
