PROBLEM TO BE SOLVED: To make a player have an expectation that a probability variable state is applied in addition to winning of a big winning when ready-to-win is formed by a specific symbol, by deciding contents of prediction performance in consideration of kinds of ready-to-win formation symbols. SOLUTION: An integrating CPU decides a ready-to-win formation symbol and a background prediction symbol respectively so that a background prediction which is executed when the ready-to-win formation symbol is formed by odd numbered symbols is executed at a high rate based on the background prediction symbol in which the degree of expectation for the big winning is set high, when a big winning determination is determined yes during a probability variable mode stay. Meanwhile, the integrating CPU decides the ready-to-win formation symbol and the background prediction symbol respectively so that the background prediction which is executed when the ready-to-win formation symbol is formed by even numbered symbols is executed at a high rate based on the background prediction symbol in which the degree of expectation for the big winning is set low, when the big winning determination is determined yes during the probability variable mode stay.
