PROBLEM TO BE SOLVED: To increase the expectation for winning (big prize) by varying the mode of figures to be display on a display part. SOLUTION: The number of figures (for example, special figure) to be displayed on a display part (for example, special figure display unit) is changed when a specific timing for example, REACH (to reach within an inch of winning)} is achieved (step S84a). Whereby the mode of figures to be displayed on the display part is varied. A ratio of a number of large prize figures and a number of total figures is also varied, so that the apparent probability of the large prize is varied. That is, the expectation for the large prize can be increased. The similar condition can be obtained when a ratio of a special figure is varied (step S84b), or when an order of figures is varied (step S84c). |
