Pro Mahjong Kiwama GB is one of those Game Boy gems that makes you appreciate how well mahjong translates to handheld play. The moment you boot it up, you're greeted with that classic tile-clicking sound and a clean, no-nonsense interface—none of the flashy stuff, just straight to the game.

It follows traditional Japanese rules, so if you're used to riichi mahjong, you'll feel right at home. The AI isn’t a pushover either—expect some solid competition, especially in the higher difficulty matches. I remember getting wrecked my first few rounds before I adjusted to the pacing.

What I love is how quick it is to pick up and play. No lengthy tutorials, just you, the tiles, and that satisfying moment when you finally complete a hand. Perfect for short sessions or long commutes. If you’ve got a soft spot for retro mahjong, this one’s a solid choice.
