PURPOSE: To improve playfulness by changing the number of lines for combining picture patterns with a simple structure. CONSTITUTION: The setting of translucent patterns is stored in a memory, a control part 5b sets the translucent patterns at the parts of upper and lower ends at the center of a middle ground picture 4b of a sprite picture 4c to be arranged on the player's side of a scroll picture 4a after a power source is turned on, and the number of lines for combining the picture patterns is changed form five lines to three lines. The traslucent patterns are set correspondingly to any information such as power source ON, game start, scroll start or the trigger of reach or probability fluctuation. Besides, when any translucent pattern is not set, the control part 5b extracts the scroll picture 4a, middle ground picture 4b and sprite picture 4c from a memory 4, overlaps those pictures and variably displays them on a display screen 3a of a liquid crystal color panel 3. |
