Dai-Mahjong on the GBA is exactly what it sounds like—no frills, just straight-up mahjong in your pocket. The tiles have that satisfying chunky pixel look, and the controls are simple enough that you’ll be matching pairs within seconds. No fancy gimmicks here, just the classic game with a couple of rule variations if you want to mix it up.

I thought the AI would be a pushover at first, but some of the later matches actually make you stop and think before slapping down tiles. And yeah, it’s portable, but fair warning: you might lose track of time during a commute because "just one more round" turns into five. If you’ve got a soft spot for old-school handheld vibes and tile games, this one’s a solid pick.
