PROBLEM TO BE SOLVED: To improve the monotonousness of a game and to suppress diminishment of amusingness of the game. SOLUTION: The game machine is provided with a performance tool on which predetermined performances are displayed and a performance controller which controls performances displayed on the performance tool. When the internal lottery is won, it is so controlled that a performance which can provide a sense of expectancy for a bonus game to a game player is displayed on the performance tool. Besides, when the internal lottery is not won, such a performance is displayed on a display only with an extremely low probability. However, it is provided with an expectancy improver for increasing the probability with which a performance which can provide a sense of expectancy for a bonus game to the game player is displayed when predetermined conditions are met, even if the internal lottery is not won.
