GAME MACHINE

PROBLEM TO BE SOLVED: To provide a game machine capable of improving an interest in a game until an advantageous game state is applied.SOLUTION: A sub-control CPU can control, under a condition that a transitional trigger combination is won, into a high-probability mode for a control to be transferred, which is easily controlled into an ART mode to become the game in a state advantageous for a player. When a predetermined special condition holds in a variation game of an ordinary mode, the sub-control CPU sets a rank to be advanced in accordance with a specific order of a plurality steps regulated in a specific order. In the case where special one of the transitional trigger combinations is won, the transfer to the high-probability mode becomes harder in the case where the rank is advanced than in the case where the rank is not advanced. In the case where a non-special one of the transitional trigger combinations is won, on the other hand, the sub-control CPU makes a control such that the transfer to the high-probability mode is made easier in the case where the rank is advanced more than in the case where the rank is not advanced.
