Real mahjong · three traditions · your browser
American rules, Chinese Classic, and Japanese Riichi — full table procedure, complete scoring, and bots that keep the game moving. No downloads, no setup: the table is already lit.
Three traditions
Each variant runs the real procedure — claims, precedence, scoring, and all. Pick one when the table opens; the host decides, everyone plays.
Jokers, the Charleston pass, and hands matched to the card in play. Fixed point values — speed over secrecy.
Chows, pungs, and a full fan table — from a quiet Pinfu to a limit-hand Thirteen Orphans. Flowers auto-replace from the wall.
Declare riichi, read the dora, and win only with a yaku. The full yaku catalog with han-based payments — dealer doubles and all.
Why here
Every claim, precedence fight, and payment is enforced by the same rules kernel — nothing is left to honor-system arithmetic.
Full fan tables for Chinese Classic, the complete yaku catalog with han-based payments for Riichi, and printed card values for American. Dealer doubles, self-draw splits — settled automatically.
A seeded Monte Carlo engine estimates how close every hand is, per variant. Turn it on and the table shows you the race.
Three difficulties, real decision-making through the same rules engine. Someone leaves mid-hand? A bot finishes it for them.
