Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of inhibiting deterioration in game taste by preventing a game from getting stereotyped by executing a novel ready-to-win performance.SOLUTION: The game machine outputs, during a variable display, a sound mode similar to a special sound mode that is intermittently output during control of a high-probability/time-shortening state (a mode during a probability variable state) and, when a result of the variable display turns out a jackpot, compared with a case of executing a variable display based on another variation pattern and turning out a jackpot, after the termination of the jackpot game state, executes transfer control to a high-probability/time-shortening state (the mode during the probability variable state) at a high rate. The game machine thus outputs, during the variable display, the sound mode similar to the special sound mode to be output in the high-probability/time-shortening state (the mode during the probability variable state), so that the player easily evokes the high-probability/time-shortening state (the mode during the probability variable state), thereby enhancing a feeling of expectation for the high-probability/time-shortening state (the mode during the probability variable state).SELECTED DRAWING: Figure 108
