PROBLEM TO BE SOLVED: To provide a novel expectation to the win/failure of a special game while mitigating the feeling of boredom due to stagnation of a game by associating a performance to change when the game stagnates for a prescribed time with a performance related to the win/failure of a subsequent special game. SOLUTION: When a display device 70 continuously displays a single ordinary-state pattern for a prescribed time or more, a performance group is shifted based on a first shift rate, when the display device 70 displays a variable display pattern based on an advantageous specific information out of lottery information, the performance group is shifted based on a second shift rate and, when the display device 70 displays a variable display pattern based on the lottery information of a special game other than the specific information, the performance group is shifted based on a third shift rate. A proportion of the second shift rate shifting to another performance group is formed different from that of the third shift rate. COPYRIGHT: (C)2009,JPO&INPIT |
