Authentic Riichi Rules
Based on the World Riichi Championship (WRC) ruleset with a complete yaku list and transparent scoring.
Features
Still Wall is built as a clear, serious single-player Riichi table: standard rules, readable information, and practical tools for learning hand by hand.
Transparent Agent Opponents
Built-in opponents scale from learner-friendly to advanced training. Difficulty is based on decision quality, yaku awareness, and defense discipline, not random gimmicks.
Optional In-Game Coaching
Coaching is optional and user-initiated. When enabled, it explains decisions and outcomes in context without automating play or taking control away from the player.
Readable Table State
Rivers, concealed rows, dora indicators, and called sets are arranged for fast parsing. Information hierarchy is designed so you can evaluate risk and value at a glance.
Tile-First Visual System
Fog and Stone palette tokens, restrained depth, and calm motion keep focus on tile decisions rather than decorative noise.
Fatigue-Safe Audio And Feedback
Event cues are intentional and low-fatigue, with independent controls for music, effects, and haptics so long sessions stay comfortable.
Practice-Oriented Match Flow
Solo play is treated as deliberate training, not filler: consistent opponent behavior, clear scoring signals, and enough pace control to build real table intuition.
Built For Stability
Stable game flow and performance-focused rendering keep play smooth and predictable across long sessions.
