Agari — Riichi Mahjong
SteamAgari is a complete Riichi Mahjong game built by a mahjong enthusiast, for mahjong enthusiasts. No gacha. No battle passes, login walls, or premium currency. You buy it once. You own it. You play it anywhere. Family friendly. Nothing to alt-tab away from. If you've been waiting for a mahjong game you're not embarrassed to have open on your screen, this is it.
The centerpiece is a 3D mahjong table rendered with a telephoto camera. The compressed depth of a long lens brings the tiles forward, making them crisp and readable without squinting or leaning in. Blue felt, warm wood rims, clean tile artwork. Every detail tuned for the long session.
Agari implements the standard riichi ruleset used across major online platforms: all 41 yaku, every yakuman, han, fu, proper scoring. Including the edge cases most games quietly skip: pao (responsibility payment), ippatsu, rinshan kaihou, haitei, chankan, nagashi mangan, abortive draws, double and triple ron. If it's in the rulebook, it's in the game. The scoring engine is open source. The Agari library (available on GitHub at agari-industries/agari and on crates.io) handles the full pipeline: hand decomposition, yaku detection, fu calculation, shanten analysis, and wait recognition. Built by the same author. Anyone can check the math. A tenpai helper shows your valid waits and tile acceptance in real time. There when you want it, out of the way when you don't.
Every chi, pon, kan, riichi declaration, and ron is called out in Japanese by a cast of distinct voice characters. Human-voiced and AI characters, each with their own sound and feel. You choose your voice; the AI opponents each get their own. The table sounds alive.
The AI plays real mahjong. Not a simplified approximation. Tile acceptance, shanten distance, 5-block theory, call decisions, discard reads. By the book. Fine-tuned parameters drive four distinct personality modes: Offensive (chases fast hands), Balanced, Defensive (avoids dealing in), and Menzen (stays closed hand). Mix and match opponents to suit how you want to play.
Every day, the same wall is dealt to every player worldwide. No accounts, no servers. Just a deterministic seed from the date. It resets at midnight. If you've played Wordle, you understand the idea.
Private online multiplayer via WebRTC. 2 to 4 players, with AI to fill any open seats. Share a room code, sit down, play. Reconnect if you drop. Or play solo against AI on a plane, a train, or your couch with the Wi-Fi off. Native support on Windows, macOS, and Linux Desktop.
Agari tracks your performance over time: first-place rate, deal-in rate, yaku frequency, han distribution. See which yaku you've won with and which you're still chasing.
Agari is made for people who want a clean, complete digital mahjong table. Not a simplified version, not a free-to-play grind. A full ruleset, smart opponents, and a game that respects your time. It's just mahjong, done right.
