ALBAN·Riichi Guide

Riichi score calculator

Pick your han and fu, choose how you won, and read off the exact payment. Everything runs in your browser — nothing is sent anywhere, and it works offline. If you are still learning what han and fu are, start with the scoring guide.

Hand value

Fu stops mattering from 5 han up. Selecting a yakuman overrides han and fu. Two special fu values: 20 fu is pinfu + tsumo only, and 25 fu is chiitoitsu (seven pairs) only — impossible combinations are removed from the list automatically.

How you won

Kiriage rounds 4 han/30 fu and 3 han/60 fu up to mangan. It is OFF in WRC and EMA rules — leave it off for tournament practice.

Reading the result

On ron, the player who discarded pays everything. On tsumo, all three opponents pay — the dealer pays a double share, and when the dealer wins, everyone pays the double share. Honba add 300 to a ron (100 from each player on tsumo), and every riichi stick on the table is worth 1,000 to the winner.

Where these numbers come from

The calculator computes the base value as fu × 2(2 + han), caps it at the limit tiers (mangan, haneman, baiman, sanbaiman, yakuman), then multiplies and rounds up to the nearest hundred. The full derivation is on the scoring guide, and every value here matches the published tournament tables — the same function generates our score table and is covered by an automated test suite.
