PROBLEM TO BE SOLVED: To enhance interest in a game by improving a performance effect and simply showing reliability and hence executing a notice performance with variation.SOLUTION: A special mode, where periods X, Y, Z are changed in this order after completion of a jackpot game, is set, the presence or absence of electric support differs between the period X (and Y) and the period Z, and the length of variation time of a pattern differs. The number of executable notice performances differs from among a plurality of notice performances of a notice type A during the respective periods X, Y, Z, thus changing the number of notice performances to be executed depending on the respective periods X, Y, Z in a special mode. Therefore, the performance effect can be enhanced by increasing variations of notice performances during a period (period X) when the number of executable notice performances is large, and the reliability can be simply shown to a player during a period (period Z) when the number of executable notice performances is small. |
