PROBLEM TO BE SOLVED: To enhance amusement.SOLUTION: By a winning of a BN [a jackpot] symbol combination during a high probability RT game, a probability variation number, which becomes as a period to be controlled to a probability variation mode, is configured to be added with an ART elapsed number related to the high probability RT game as the object [as the number to add]. Accordingly, when adjacent to a start of the high probability RT game, in a state where a residual game number is left more than adjacent to the end (adjacent to 30th round), a state can be created where the variation games can be played at ease. On the other hand, when adjacent to an end of the high probability RT game (adjacent to 30th round), in a state where an elapsed game number is elapsed more than adjacent to the start, a state can be created where an addition to the probability variation number can be expected. In this way, even in the high probability RT game, the game elapsed number that changes according to a timing when the BN symbol combination is won is added to the probability variation number. Accordingly, while changing a feeling of expectation toward the high probability RT game, game amusement during the high probability RT game can also be enhanced effectively.SELECTED DRAWING: Figure 12 |
