PROBLEM TO BE SOLVED: To increase variations of performances by decoration symbols.SOLUTION: A variation performance part 411 executes, on the basis of a symbol variation time, a normal variation performance, a first special variation performance different from the normal variation performance, and a second special variation performance executable after the first special variation performance. A symbol performance part 412 variably displays decoration symbols. The decoration symbols include first special decoration symbols that are stationarily displayed to suggest that the first special variation performance may be executed, and second special decoration symbols for suggesting that the second special variation performance may be executed. When the first special variation performance is executed by the variation performance part 411, the symbol performance part 412 can temporarily stationarily display the first special decoration symbols at first timing before the first special variation performance is executed, and, when the second special variation performance is executed by the variation performance part 411, can temporarily stationarily display the second special decoration symbols at second timing later than the first timing. |
