Filed: 2019-06-05
Abstract: To provide a game machine and the like which are provided with conventional bonus combinations and an ART function as a third bonus combination, and which can further increase a net increase medals per one game.SOLUTION: In a general game, an RBB as a bonus combination is won in an internal lottery, and if a winning of the RBB is achieved in the game, the RBB game starts from a next game. The RBB game finishes when a payout of medals (tokens) exceeds a prescribed number of 120 medals and a normal replay state having a low winning probability of a replay combination in a lottery is brought about from a next game. If an achievement of winning the RBB is avoided, a high probability replay game state (RT1) is brought about with a bonus combination having won in the internal lottery (amid an RBB inside). If an AT is activated in the amid game, and if winning of all small combinations are achieved including a first small combination to a third small combination, a net increase medals exceeding averagely about 4 medals/game can be achieved. In the RBB game, the first small combination, the second small combination and the third small combination become simultaneously to be won in a lottery, which turns out a reduction of 26.4 medals per one RBB game by calculation.SELECTED DRAWING: Figure 53
