PROBLEM TO BE SOLVED: To cause expectation to continue even when a notice performance image that appears later is lower in winning expectation degree than an image that has appeared previously.SOLUTION: Many kinds of notice performance belonging to many kinds of notice performance categories are included, it is defined so that expectation degree is different between one notice performance and another notice performance belonging to the same kind of notice performance category, appearance control of notice performance by an image at a prescribed prior timing and an image at a specific timing can be performed at a timing before and after a symbol variation display game. The image at the prescribed timing and the image at the specific timing are determined from the display mode categories to which hues and/or patterns mutually different are applied as notice performance belonging to first and second same notice performance categories. A specific timing display mode is determined to be fewer in the number of categories than a prescribed timing display mode and is composed of a display mode category common to the prescribed timing display mode and higher in expectation degree of display mode categories in the prescribed timing display mode.SELECTED DRAWING: Figure 48 |
