PROBLEM TO BE SOLVED: To loop a big winning game and a probability variable game and to provide a discharge ball configuration where prize balls are present at all times.SOLUTION: The number of times of opening a big winning port in one big winning game and the number of winnings for ending each opening of the big winning port are set so that the time from the start to the end of the big winning game becomes prescribed short time (5-8 seconds), the winning probability of big winning drawing in probability variation is set at a high value (1/3.7) to win by several times or less of drawing, in which it is expected at a high probability that the winning is included in the holding storage of special symbols that has reached an upper limit, the opening of a normal electric Yakumono (accessory) by the winning in the normal symbol drawing in time shortening is performed by an opening/closing pattern for two or more times, and the time from the start to the end of the opening/closing pattern is set to be longer than the time from the start to the end of the big winning game (1.4 seconds opening ×4 times, an interval of 1 second). |
