Play 4 Nin Uchi Mahjong (Japan) (Rev A) Online
Sit down with three friends and outmaneuver each other with careful tile plays—that satisfying clack when you drop one seals the deal. Pure NES mahjong, no fluff, just tense rounds where every discard could cost you.

4 Nin Uchi Mahjong is a Nintendo Entertainment System title released in Japan, developed by Nintendo R&D1. It arrived during the NES era when digital adaptations of traditional games were becoming more common, offering a straightforward take on the classic tile matching game without extra modes or elaborate presentation.
You control one of four players aiming to form a winning hand by drawing and discarding tiles. The main objective is to complete specific tile combinations before your opponents. Signature mechanics include calling tiles from other players' discards to complete sets, and carefully managing your hand to avoid giving away advantages. The pacing is deliberate, with each round demanding attention to both your tiles and your rivals' strategies. It feels like a quiet battle of wits, where patience and observation often lead to victory.
