PROBLEM TO BE SOLVED: To keep the frequency of executing a display game in a unit time constant even when the probability distribution of appearance ratios in a plurality of kinds of performance patterns developed in the display game is changed. SOLUTION: In the game machine, a pattern information storage means 202 stores in advance a plurality of kinds of information tables 220 relating the appearance ratios in a plurality of performance patterns to performance time required for their execution for every performance pattern and having different probability distributions of appearance ratios allocated to the performance patterns. Each of the information tables adjusts the performance time of several performance patterns so as to ensure that average performance time in which the product of the appearance ratios and performance time for every registered performance pattern is added for all the performance patterns will agree with a prescribed reference average time. A game control means 203 selects a performance pattern in accordance with a probability distribution shown by selected one information table and performs a display game in accordance with the pattern. An announcement relating to the selection of the information table is made through a sound output device. COPYRIGHT: (C)2009,JPO&INPIT |
