PROBLEM TO BE SOLVED: To provide a game machine which does not give disadvantage to a player even when ball clogging occurs and a glass frame is opened during a big winning state. SOLUTION: The game machine comprises: a main control board 261 for controlling a game; a power board 313 including a power source circuit and a power failure circuit; a first pattern display device 42 for variably displaying two or more of identification information; and an opening detection switch SW1 for detecting the opening of a front surface frame set 14. The opening detection switch SW1 is connected with the main control board 261. The main control board 261 monitors the presence/absence of opening detection signals from the opening detection switch means SW1, and when judging that the opening detection signals are outputted, temporarily stops a game state.
