Hunky Dory RiichiBETA

A free browser trainer for Japanese riichi mahjong — learn the game from zero, then practice full hands against three AI opponents with beginner hints and real scoring.

About this beta

This is an early, free trainer. The scoring engine is heavily tested (yaku, fu, dora, payments — the math is the trustworthy part). The AI is a work in progress: it plays a reasonable game at three difficulty tiers, but strong players can and will outplay it. That's part of the point of a beta — found a bug, or beat the AI in a silly way? Tell us: riichi@hunkidori.io — or hit the “report / I beat the AI” button right at the table.

This free beta records anonymous gameplay (no accounts, no personal data) to help improve the game and its AI.
