Abstract: To provide a technique for avoiding a player's disadvantage beforehand.SOLUTION: Although the number of time-shortening times is granted for eight times to a first special pattern and for 70 times to a second special pattern in completion of a jackpot, only the remaining number of time-shortening times of the second special pattern is displayed on the screen of a liquid crystal indicator 42. Therefore, a mode of a rightward shooting suggestive performance in variation of the first special pattern is allowed to differ in steps according to the remaining number of time-shortening times of the first special pattern, and a normal rightward shooting suggestive pattern (A), an emphasis rightward shooting suggestive pattern (B), and an ultra-emphasis rightward shooting suggestive pattern (C) are selected when the remaining number of time-shortening times is six to eight, fourth to five, and one to three, respectively. In this manner, by emphasizing a rightward shooting display in steps as the remaining number of time-shortening times of the first special pattern decreases, a player's attention is attracted and the player is allowed to recognize that the player should perform rightward shooting (the player suffers from disadvantage if the player does not perform rightward shooting), thus effectively promoting rightward shooting. Accordingly, the player can avoid suffering from disadvantage beforehand since the player continues leftward shooting and time-shortening is completed.SELECTED DRAWING: Figure 73
