PROBLEM TO BE SOLVED: To provide a game machine which can maintain the balance of profits between game parlors and players without stirring up gambling spirits unnecessarily. SOLUTION: When the BB (big bonus), CT (challenge time) or RB (regular bonus) is won under the state of the "ongoing normal game" 101, the shift is made to the state of the "ongoing increase bonus" 102 or when a reduction bonus combination (r, y or r) is won, the shift is made to the "ongoing reduction bonus" 103. The combined probability of the BB, CT and RB under the state of the "ongoing normal game" 101 is determined by (1/80+1/100+1/900)≈1/42. This means that the shift to the "ongoing increase bonus" 102 occurs at a high probability. On the other hand, the probability of the shift of the reduction bonus combination (r, y or r) to the state of the "ongoing reduction bonus" 103 is high at 1/44. The state of the "ongoing normal game" 101 can be called as "high probability lottery zone" meaning the lottery at a high probability for the shift to the "ongoing increase bonus" 102. Under the "ongoing reduction bonus" 103, lotteries are carried out respectively for minor winning combinations and the SCT (special challenge time), SB (special bonus) and RB (regular bonus).
