Abstract
This invention aims to provide a game machine which can offer exciting and varied game aspect. In the game machine, certain symbol combinations (group [C] and [E]) are set as a prize mode only when they occur in B.B (big bonus) game. The combinations in group [C] are not regarded as a prize mode when they occur during the ordinary regular game. These combinations are new to the player because the player encounters them only when the game shifts to the big bonus game. This gives a fresh impact to the player and the player can enjoy a variety in the big bonus game, which does not occur in the ordinary regular game.
