PROBLEM TO BE SOLVED: To improve the interest in a game by effectively enhancing the expectation of a player in a slot machine having a stock function. SOLUTION: Even if a bonus winning flag is set, it is impossible to obtain the bonus winning due to the control of a game state by an RT (replay time). When the RT is reset after winning an RT resetting lottery, it is possible to obtain the bonus winning. The winning probability of the RT resetting lottery may be changed depending on a resetting probability change lottery. When the RT is reset or the resetting probability is changed from low probability to high probability or the bonus winning is newly obtained (the first winning or the increase of the stock number), the probability of selecting a presentation A or a presentation B as a presentation mode becomes high. In other words, when the presentation A or B is executed, execution of the reset of the RT, the change from the low probability to the high probability or the bonus winning is highly likely.
