<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of preventing such a situation that a player's sense of expectancy is all the more impaired by the presentation on the probability of winning a jackpot. <P>SOLUTION: When a presentation control unit receives a stage lottery command (S2201), a stage random number is obtained and determined (S2202 and S2203). RAM clearing flag decision is executed (S2204), and if the flag is on, whether the current winning is a minor jackpot or a concealed probability variation is determined (S2205). If it is determined that the current winning is the minor jackpot, etc., the RAM clearing flag is turned off (S2206). If it is determined that the current winning is not the minor jackpot, etc., information on the stage selected in the last lottery is obtained (S2207). Whether the current degree of expectancy for a high probability is higher than the last one is determined (S2208). If it is determined that the current degree is higher, a stage with a lower degree of expectancy for a high probability than the current degree is selected from a plurality of stages, and if the current degree is not higher, a stage selected in the current lottery is selected, and set in a RAM (S2209-S2211). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
