PROBLEM TO BE SOLVED: To provide a technology which simplifies performance management while reducing the number of variation patterns.SOLUTION: In performing variable display of symbols, any one of many kinds of variation patterns with variation time different from one another is determined. With respect to the performance pattern, many kinds of performance patterns which include a special performance pattern including special performance which varies the degree of possibility for a result of an internal lottery to be winning and a basic performance pattern not including the special performance are regulated; the special performance pattern and the basic performance pattern whose times for execution needed for executing variable display performance are set identical in many kinds of performance patterns are regulated respectively. In determining a performance pattern, both the special performance pattern and the basic pattern to each of which the identical time for execution is set are associated with variation patterns whose settings of variation time are identical. With respect to the special performance pattern, a part of a structure of at least one performance before and after the special performance is omitted. |
