PROBLEM TO BE SOLVED: To switch the probability table of general play while being related with a so-called bonus game. SOLUTION: A probability table 60 is provided with a low probability table 61 and a high probability table 62 having prize winning probability higher than that of the low probability table 61. The switching of probability table 60 between the low probability table 61 and the high probability table 62 is controlled by a probability table switching means 70. After the end of special play due to a special play means 90 is waited and changed into general play, the probability table switching means 70 switches the probability table 60 from the low probability table 61 to the high probability table 62 on the condition that the low probability table 61 is used. |
