PROBLEM TO BE SOLVED: To improve interest to a game by making a game player possess a performance value different from a sense of anticipation to a probability variation big jackpot with respect to a double Riichi performance including a large number of non-probability variation symbols as a Riichi symbol. SOLUTION: As a Riichi performance, a single Riichi performance and the double Riichi performance can be performed, and it is decided that the double Riichi performance should be performed at a high ratio compared with the case that "losing" is decided when "big jackpot" is decided. Furthermore, when it is decided that a probability variation promotion performance should be performed, and when it is decided that the double Riichi performance should be performed, a double Riichi symbol is decided so that the non-probability variation symbol becomes large in number than that of a probability variation symbol.
