PROBLEM TO BE SOLVED: To provide a game machine, keeping constant the number of times for performing a display game in a unit time even in the case of changing the probability distribution of occurrence rate in two or more kinds of presentation patterns developed in the display game. SOLUTION: A reference value storage means 204 previously stores a reference average time, which is a reference value of average presentation time obtained by adding the products of occurrence rate and presentation time of every presentation pattern concerning presentation pattern. When the probability distribution of occurrence rates assigned to two or more kinds of presentation patterns is changed, a presentation time changing means 206 changes the presentation time of one or two or more out of these presentation patterns of two or more kinds so that the average presentation time calculated according to the probability distribution of occurrence rate after changing. Information on change of the probability distribution of occurrence rates is given through a voice output device 510. COPYRIGHT: (C)2009,JPO&INPIT |
