PROBLEM TO BE SOLVED: To provide a game machine capable of effectively utilizing each of plural operation means prepared to change a performance.SOLUTION: A game machine includes: performance execution means for executing a specific performance; depression operation means and rotational operation means that a player can operate; depression operation effective period setting means for setting a period when the depression operation means becomes effective during execution of the specific performance; and rotational operation effective period setting means for setting a period when the rotational operation means becomes effective during the execution of the specific performance. The rotational operation effective period setting means sets a rotational operation effective period with the proviso that the performance execution means has executed the specific performance. The depression operation effective period setting means sets a depression operation effective period with the proviso that it is determined that predetermined rotational operation using the rotation operation means has been performed within the rotational operation effective period.SELECTED DRAWING: Figure 7 |
