When a wild symbol 311a is fixedly displayed, a gaming machine of the present invention preferentially displays a fixedly displayed wild symbol 311a over a symbol 311 rearranged behind the fixedly displayed wild symbol 311a until rearrangement is completed. When the plurality of symbols 311 rearranged including the symbol 311 rearranged behind the fixedly displayed wild symbol 311a satisfy a predetermined relation, the symbol 311 rearranged behind the fixedly displayed wild symbol 311a is preferentially displayed over the fixedly displayed wild symbol 311a. When the predetermined relation is not satisfied, the fixedly displayed wild symbol 311a is preferentially displayed over the symbol 311 rearranged behind the fixedly displayed wild symbol 311a.
