SameGame (鮫亀) is a Satellaview-compatible Slotted Cartridge game. The game was playable on its own without any data packs, it was playable in conjunction with 8M Pack data downloaded via the BS-X cartridge, and it could also be used together with the separately released Write-protected memory packs, Character Cassette and Character Data: Tengai Makyo. The game was eventually used to hype the release of the promotional game of the same family, UNDAKE 30 SameGame.
