Abstract: In a game apparatus, a plurality of puzzle elements each having a preset attribute are arranged within a predetermined area on the screen of a display device. A puzzle element arrangement pattern within the predetermined area is altered in accordance with a player's operation. In the game apparatus, when the arrangement pattern is altered, a ring-like puzzle element group is identified, which consists of puzzle elements having the same preset attribute and being adjacently arranged in a closed ring within the predetermine area. In the game apparatus, any puzzle element is deleted, which is arranged in a position determined by the identified ring-like puzzle element group defined by the ring-like puzzle element identification means.

Abstract: A game machine includes an LCD. The LCD displays a plurality of puzzle elements of different kinds. When a player uses an input means such as an operating key and a touch panel to designate some puzzle elements consecutively in the manner of one-stroke drawing, the kind of the designated puzzle elements is changed to another one. One stage of game is cleared if display of the changed puzzle elements has entered a predetermined state or met a predetermined requirement.

Abstract: A game system includes a game machine in which first and second cartridges can be simultaneously inserted. In a ROM of the first cartridge, a first game program is stored. When data is stored in a reserved area in a flash memory of the first cartridge, the first game program can be executed using the data. For example, when both of the cartridges are inserted simultaneously in the game machine, according to an instruction of a player, a writing program stored in the ROM of one of the cartridges is executed, and additional data stored in the ROM of the second cartridge, for example, image data used for generating a game screen is written into the flash memory of the first cartridge.
