Pure Riichi Rules
Based on WRC ruleset. Every yaku, fu calculation, and scoring edge case implemented correctly — not approximated.
Still Wall
Riichi Mahjong
A calm, focused implementation of Riichi Mahjong for iOS.
Designed for thoughtful decision-making and long-session comfort.
Built-In Agent Opponents
Four difficulty tiers from learner-friendly to advanced, with opponents that use defense discipline and yaku awareness rather than random play.
Optional In-Game Coaching
Enable coaching to see the suggested discard and why it's recommended. Turn it off when you don't need it — it never plays for you.
Calm Visual Language
No casino animations, no countdown timers, no sound pressure. Just the table, your tiles, and the decision.
