PROBLEM TO BE SOLVED: To suppress the lowering of the amusement of a game by determining whether or not producing an odd number big win based on a symbol determination table. SOLUTION: In a big win game playing process S44, at first, CPU transmits a lottery display command for commanding to display that a probability variable lottery is executed by the passing of a lottery gate, to a sub integrated board in parallel with the big win game. Then, the CPU determines whether or not the game ball passes through the lottery gate, when determining that the game ball passes through the lottery gate, acquires a probability variable determination random number and determines whether or not producing the probability variable big win. Especially, when the odd number big win, a probability variable rush-in probability is defined as 3/4, while in a case of an even number big win, a probability variable rush-in probability is defined as 1/4, and the probability of the probability variable lottery is changed according to symbols when the big win is lead.
