BS Zootto Mahjong on SNES is one of those weird Japan-only releases—basically a straight-up mahjong sim, but someone hacked it to tweak the AI behavior. The original was just you versus the same predictable computer opponent, but this version mixes things up a little. Still plays like classic mahjong, just with slightly less robotic opponents.

If you're into tile-matching games, it's got that satisfying click-and-slide feel of the real thing, though the UI is very much '90s SNES—chunky menus, simple graphics. Not the flashiest way to play mahjong, but there's something cozy about it. Just don't expect online multiplayer or anything fancy.
