PURPOSE: To reduce the difference between advantages and disadvantages in play and to provide uniform service to players by randomly deciding whether or not the displayed results of a variable display device for which a lead-out time period is differentiated matche and lead-out controlling the displayed results so as to be the display results. CONSTITUTION: When numbers displayed in the center parts of the drum-like variable display parts 58a to 58c of the variable display device 50 are same as each other and 7 on F is displayed form five kinds of the variable display device 56, the specified play state of big winning is attained and the probability of becoming the specified play state of the big winning is automatically changed and set based on a counted value at the time of the reset of a start winning number counter for counting winning signals to start winning ports 20a to 20c. Then, automatic selection is performed so as to lower the generation probability of the specified play state of the big winning in the next unit time as a winning ratio to the start winning ports 20a to 20c per previous unit time is raised. Thus, the generation frequency of the specified play state of the big winning in a certain prescribed period is adjusted to be uniform at all times. |
