In the gaming machine 1, by removing symbols of a particular type and moving a following symbol, the ratio of symbols of types other than the particular type becomes higher in the symbol array formed on the display unit 27, and it is easier for the symbol array to configure a winning combination. Because the chance of winning is higher after the particular type of symbol is removed in this manner, it is possible to provide a new type of game where the interest of the player can be maintained or improved after the symbols are removed. ## Claims ### Claim 1 One or more non-transitory computer-readable storage media, having computer executable instructions embodied thereon, wherein when executed by a processor, the computer-executable instructions cause the processor to: display a game screen using computer generated images on a display unit, the game screen including a grid having a plurality of display elements in a predetermined arrangement forming a plurality of rows and columns;
