Abstract
Probability of prize occurrence is easily controlled without provision of a blank between symbols on a reel. A gaming machine 300 includes a lower image display panel 141 configured to variable-display symbol arrays 170 each including a plurality of normal symbols 501 and a plurality of crest symbols 502 arranged among the normal symbols 501, and then rearrange the normal symbols 501 and the blank symbols 502 in a symbol display region 150 having a matrix of cells. The gaming machine 300 generates a line win or a scatter win when the normal symbols 501 are rearranged on the lower image display panel 141 in a predetermined manner, and generates a crest win which is lower than the line win and the scatter win when a predetermined number or more of the crest symbols 502 are rearranged.
