PURPOSE: To suppress the special kind of specified display condition from being frequently extracted out of a storage means by periodically updating numerical data by operating a numerical data updating means for success/failure decision, and using this result for deciding whether or not a specified display condition is to be displayed. CONSTITUTION: Concerning a controller for a Japanese pinball game (pachinko) machine provided with a variable display device 3 for special picture patterns at the central part of a play area 10 and a variable prize winning feeding path 4 under this device 3, this controller is equipped with a success picture pattern table storing the display conditions of success picture patterns. When the generation of great success is decided in advance, the success picture patterns are extracted by referring to the picture pattern table based on the extracted value of a random counter, and the same success picture patterns are displayed on the variable display device 3. Besides, the success picture pattern table stores establishment fluctuation picture patterns for improving the generation probability of great success so that a display condition deciding means can not frequently extract the establishment fluctuation picture patterns out of the success picture pattern table for certain time when the great success is generated. |
