To provide a game machine capable of executing performance display without lowering interest in a game.

Since the mode of a change destination is determined by using a normal mode determination table at high probability time wherein the ratio of determining a special mode is higher in the case that control is executed to a high probability state than in the case that control is not executed to the high probability state, the ratio of judging a 15R probability variable big winning becomes high when control is executed to the special mode and a mission performance is executed, and the performance of achieving a mission is easily executed. Thus, it is possible to prevent the decline of expectations of the special mode, that is the mission performance, due to a shift to another mode without executing the performance of achieving a mission, although control is executed to the special mode and a mission performance is executed.
