Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing malfunction.SOLUTION: One information group used for control by control means is selected from storage means by information group selection means. A start position of a predetermined information group from among storage areas for storing a plurality of information groups is shown by start position designation means, and one information group is selected by information group selection means, based on a start position shown by the start position designation means. Thus, a start position of a predetermined information group may be read in control processing for designating one information group, and information for composing the information group does not need to be described in a program individually. Therefore, since many pieces of information do not need to be rewritten in a program in diversion of the program to another model, occurrence of a rewriting mistake of values can be suppressed.
