PROBLEM TO BE SOLVED: To display an image of a previous-announcement performance at a normal probability when a previous-announcement mode 1 is set, and display an image of the previous-announcement performance at a lower probability when the mode 2 is set, although a previous-announcement performance-determining table shared by the modes 1 and 2 is used. SOLUTION: A plurality of determination values are selected from the previous-announcement performance table according to a selection result of a variation starting command. The updated result of a random counter SR4 is detected, and compared with the determination values respectively to execute lotteries to determine whether an image of the performance is to be displayed or not by a number of times limited to a result set by a lottery number counter SN4. The lottery number counter SN4 is set at a normal value at a set of the mode 1 and at a lower value at a set of the mode 2. Thereby, when the mode 1 is set, a large number of the lotteries are executed and the image of the performance is displayed with the normal probability. When the mode 2 is set, a small number of the lotteries are executed and the image of the performance is displayed with a probability lower than the normal one. COPYRIGHT: (C)2010,JPO&INPIT |
