PROBLEM TO BE SOLVED: To diversify the number of net increase of tokens obtained in a specific game zone. SOLUTION: A plurality of upper limit values of the number of net increase of tokens in a big bonus (BB) mode are set. When a winning role determined by a success hand determining part 32 is a BB transition hand, an upper limit value of the number of net increase of tokens is selected by an upper limit value selecting part 40. If the success hand determined by the success hand determining part 32 in the BB mode is a group winning pattern (for example, the success hand "jack" in the BB mode), a different number calculating part 37 calculates the difference between the value counted by a net increase number counter 35 and the upper limit value. A pattern combination determining part 47 determines pattern combinations in the game by using a selection table according to the value calculated by the different number calculating part 37.
