PROBLEM TO BE SOLVED: To provide a game machine capable of giving a good quality of a performance and a sense of expectation to a player even if an opportunity for outputting performance sound with large volume is reduced.SOLUTION: When a specific performance is executed, performance sound is outputted with sound volume smaller than prescribed sound volume by a speaker for a special period during variation of a pattern. A probability of selection in winning is higher when the special period exists than when no special periods exist. Therefore, even if an opportunity for outputting performance sound with large volume is reduced, a sense of expectation can be given to a player. Further, since a volume pattern in which the special period exists appears also in losing, an opportunity for reducing sound volume of performance sound is frequent, thus contributing to silencing in a parlor. A volume pattern in which no special periods exist regardless the same kind of performance without providing an exclusive performance for reducing sound volume of specific performance sound, thus passing a good quality of a performance to the player.SELECTED DRAWING: Figure 19 |
