PROBLEM TO BE SOLVED: To provide a Pachinko game machine for reliably finding a fraudulent act performed by opening a game machine frame. SOLUTION: The Pachinko game machine 1 includes: a frame opening SW 44 (opening detection means) to detect opening of the game machine frame 40 while a game board 2 is mounted to the inside of the openable and closable game machine frame 40; a performance control substrate 22 (performance control means) for executing various performances using performance devices 4, 17, 18, 19, 29; and a frame opening frequency counter 60 (counting storage means) for counting the number of opening times of the game machine frame 40 detected by the frame opening SW 44 for storage. The performance control substrate 22 executes a different performance according to a counting value stored by the frame opening frequency counter 60. Accordingly, simply by confirming the performance under execution at a glance, one can recognize how many times the game machine frame has been opened. COPYRIGHT: (C)2012,JPO&INPIT |
