<p><P>PROBLEM TO BE SOLVED: To provide a pachinko game machine which makes the endpoint of a high probability condition sufficiently uncertain. <P>SOLUTION: The pachinko game machine can switch between a high probability condition in which a lottery for a jackpot is held with high winning probability and a low probability condition in which a lottery is held with low winning probability, draws lots to decide whether the high probability condition is to be ended during the high probability condition and judges whether the high probability condition is to be ended in accordance with the result of the lottery. When the result of a lottery for a jackpot is a blank and the end of the high probability condition is judged, the high probability condition is switched to the low probability condition. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
