To provide a game machine capable of improving game properties and fun as well as performance effects by executing a special game performance different from a regular game performance during symbol variable display, executing a specific game performance different from a regular one for a plurality of symbol variable displays as a performance based on a prior determination, and effectively executing the performances.

On a basis of a determination result of a prior determination means 34b, a specific game performance execution means 62 can execute a first specific zone performance having a low expectation degree for executing a special game and a second specific zone performance having a high expectation degree for performing the special game, as specific zone performances different from a regular performance for a plurality of special symbol variable displays by a special symbol display control means 35. When the prior determination means 34b determines not to execute the special game and determines to decide a specific symbol variation mode, the specific game performance execution means executes the first specific zone performance at a probability higher than that of the second specific zone performance.
