PROBLEM TO BE SOLVED: To display the probability of big scoring by providing a probability fluctuating means for fluctuating the probability of a display device being stopped with specific patterns and a probability display means for displaying the probability fluctuated by the probability fluctuating means. SOLUTION: If a probability fluctuating routine is executed during a main routine, a current-pattern display part 15a, a previous-pattern display part 15b, and a before-last-pattern display part 15c in a probability display part 15 are each shifted to the left, and the current big-scoring pattern is displayed in the current-pattern display part 15a. If the big-scoring pattern is a specific one, this specific pattern and a high-probability display pattern 19 showing a high- probability mode are displayed in the current-pattern display part 15a. If the big-scoring pattern is a normal one, simply this normal pattern is displayed in the current-pattern display part 15a. Thus when big scoring is achieved with the special pattern, the player can notice that the high-probability mode has been selected. |
