PROBLEM TO BE SOLVED: To provide a game machine for performing lotteries of different performances individually in two states (low- and high-probability times), wherein two lottery tables needed in the prior art are reduced to one thereby to reduce a data capacity.SOLUTION: In two states (at low- and high-probability times), reference is made to the same common lottery table. In the common lottery table, a performance having a high frequency at the low-probability time is set on the upper side whereas a performance having a high frequency at the high-probability time is set on the lower side. The numerical values of the common lottery table are sequentially added to select the performance on the basis of an addition number at the time instant when a predetermined reference value (a random number value) is exceeded. An ascending operation to add sequentially from the higher numerical value is performed at the low-probability time, whereas a descending operation to add sequentially from the lower numerical value is performed at the high-probability time. By inverting the reading order of the table, lottery results different in the two states can be acquired, while using the common table. |
