Abstract
A gaming machine that is capable of imparting diversified variations to the play of a bonus game is provided. A main CPU displays a selection screen in a case where a feature game trigger is established, and causes a player to select one of a free game and a roulette game. In a case where the free game is selected, a total of values of BONUS symbols that correspond to the feature game trigger is determined as the number of free games. On the other hand, in a case where the roulette game is selected, a game is completed by carrying out roulette game processing once, and the amount of payouts is determined based on the number of free games. The free game and the roulette game are respectively set so that expectation values of the number of payouts are equal to each other.
