PROBLEM TO BE SOLVED: To provide a game machine with which a game can be played fairly by enabling backup of data even for prize balls ejected after the occurrence of the abnormal state of a power source, and thereby enabling return to a normal state without overlapped processing. SOLUTION: The game machine 100 is provided with a controller 20, an ejection mechanism and a prize ball detection means. The machine 100 is further provided with a power source abnormality detection means and a backup means. In the normal state, the controller performs ejection scheduled number storing processing, adding storage processing and subtracting storage processing. When the abnormal state is detected by the power source abnormality detection means, the controller performs only the adding storage processing and performs backup processing. In the case of returning from the abnormal state to the normal state, the controller calls the counter values of a prize ball counter and a prize ball detection counter stored in the backup means and information showing the advancing state of a control program and performs program restarting processing of restarting control concerning the game from the advancing state of the stored control program.
