PROBLEM TO BE SOLVED: To provide a pinball game machine which generates a jackpot with the two chances of a jackpot lottery, wherein the situation disadvantageous to a player is hard to be generated by utilizing the previous reading function of the suspension storage of the lottery. SOLUTION: The pinball game machine has a control means which performs the first determination processing which determines whether a numerical value corresponding to a jackpot exists by comparison with a usual probability table among numerical values for jackpot determination stored in the first suspension memory unit between two suspension memory units and the second determination processing which determines whether a numerical value corresponding to the jackpot exists by comparison with a high probability table among the numerical values for jackpot determination stored in the second suspension memory unit. The control means generates announcement information, which can be recognized by the player, so that the lottery chance corresponding to the first suspension memory unit may not be formed when the result of the first determination processing is at least "absence" and the result of the second determination processing is "existence".
