PROBLEM TO BE SOLVED: To hold back players' avoidance of games in a game machine having the function of restricting the continuation of the variable probability state. SOLUTION: When the starter prize is won, the jackpot lottery is carried out at a first jackpot lottery winning probability or at a second jackpot lottery winning probability set more advantageous for players as compared with the first jackpot lottery winning probability (S20). When the provision of the jackpot is determined (YES at S30), a lottery is carried out at a rate of jackpot continuation set at S50 to determine the provision of the variable probability jackpot or the normal jackpot (S70). When the provision of the variable probability jackpot is determined, the jackpot lottery winning probability is turned to the second jackpot lottery winning probability (S120) until the provision of the normal jackpot is determined (NO at S80). Moreover, the frequency (frequency of jackpot continuation) at which the jackpot game is provided successively under the state (variable probability state) with the second one of the jackpot lottery winning probability (S40 and S90). The rate of the jackpot continuation is reduced as the frequency of jackpot continuation increases (S50), and the rounds of jackpot game are increased (S60). COPYRIGHT: (C)2009,JPO&INPIT |
