Play 4 Nin Uchi Mahjong (Japan) Online

4 Nin Uchi Mahjong is that no-nonsense NES tile game you’d find in old Japanese arcades—just straight-up mahjong without any fluff. The pixels are chunky, the music’s got that tinny NES charm, and you can either go solo against the CPU or squeeze three friends around the TV for some chaotic multiplayer. No tutorials here, though—if you don’t already know how to play, you’ll be squinting at tile combinations like "wait, is this a pon or a chi?"

What I love is how unapologetically simple it is. No fancy animations, no power-ups—just you, some questionable AI opponents (they either fold instantly or pull off insane comebacks), and that satisfying clack of tiles. It’s the kind of game where you’ll accidentally discard the wrong piece and immediately regret it. Perfect if you miss the days when multiplayer meant elbowing your friends for screen space.
