Hand Calculator

Beta

Build a 13-tile hand, add the winning tile, and score it for whichever ruleset you're playing.

This calculator is a practical scoring aid built from public rule references, not a certified implementation of any official rulebook. Rare or edge-case patterns may be missing or approximated -- each ruleset's tab notes its specific gaps below. Always defer to your table's own house rules.
Covers the common yaku and standard yakuman, including kans/kongs (Sankantsu, Suukantsu, and kan fu). Not modeled: red fives (aka dora) and the rare double-yakuman distinction for a 13-sided Kokushi wait.
