PROBLEM TO BE SOLVED: To avoid complicating game properties and provide a variety of game properties in a model of a machine having a plurality of conventional first type functions. SOLUTION: A special game execution means puts a first variable winning opening or a second variable winning opening in an opened state to ensure that an expected acquisition quantity of prize balls in the case where the stop identification information of a second identification information is a third or a fourth prescribed mode is smaller than the expected acquisition quantity of prize balls in the case where the stop identification information of the first identification information is a first or a second prescribed mode. A game condition control means shifts to a high-probability drawing condition where the probability of drawing for a special game is higher than a normal game condition after a special game based on the prescribed mode ends when the stop identification information of the first identification information is a second prescribed mode or the stop identification information of the second identification information is a fourth prescribed mode and shifts to a long-hour opened condition where the variable member gets into an opened condition relatively longer than the normal game condition after the special game based on the prescribed mode ends when the stop identification information of the first identification information is a first prescribed mode.
