A gaming machine includes: a plurality of first video reels 31, 31, . . . on which partial pictures of one entire sheet are arranged, respectively; and a plurality of second video reels 32, 32, . . . on which plural types of symbols are arranged, respectively. Operating a start button starts a base game. After the first video reels 31 and the second video reels have been displayed in a rotating manner on a first liquid crystal display panel 11, each of the first video reels 31 is displayed in a stopped state. Completing one entire sheet by the partial pictures displayed in a stopped state starts a second game corresponding to the competed picture. In the second game, like the base game, symbols arranged on the second video reels are employed. Thus, players can intuitively comprehend that a second game associated with the base game is started. Thereafter, an activated area is determined, and a prize is established if specific symbols have stopped in the determined activated area.
