ABSTRACT:
A player initially sets the degree of difficulty of a display type game, and if desired, more than one player may participate with each player selecting an associated level of difficulty. First and second objects having different shapes, e.g. capsules and viruses, and different characteristics, e.g. different colors or shadings, are displayed in a predefined display area. First objects are generated based on random number data stored in a ROM and displayed as "falling" in a vertical direction across the predefined display area. Coordinate positions of the first objects on the display are changed by a player operating a controller. Second objects are displayed at arbitrary positions in the display area based on random number data. If a prescribed number of at least a portion of first objects and/or second objects having the same type characteristics are detected as being continuously aligned in a vertical or lateral direction, those continuously aligned objects are erased. Remaining portions of first objects (or remaining first objects) previously supported by erased objects are displayed as falling in the vertical direction to the lower region of the prescribed displayed area. When all second objects are erased, the game is successfully completed.
