Riichi scoring explained
A riichi score comes from two numbers: han, the doubling steps that yaku and dora give, and fu, the small points for the shape of the hand. This page shows how to count both, how they turn into points, and who pays.
The scoring in four steps
- Count the han. Add the han of every yaku, then add one for each dora, ura dora and red five in the hand.
- Count the fu. Do this only if the hand is under 5 han, and round the total up to the next 10.
- Find the base value. The hand is worth fu x 2^(han + 2), capped at 2,000. From 5 han on, the value comes from the limit table instead.
- Work out the payments. Take them from the base value, then add the counters and the riichi sticks.
Counting fu
Fu are added to a base of 20. Add every row that applies, then round the total up to the next 10. Seven pairs is a fixed 25 and is not rounded.
| Situation | Fu |
|---|---|
| Winning (base) | 20 |
| Closed hand won by ron | +10 |
| Won by tsumo (not with pinfu) | +2 |
| Winning on the middle of a sequence, on the 3 or 7 of 1-2-3 or 7-8-9, or on a pair | +2 |
| Pair of dragons, your seat wind or the round wind | +2 |
| Open triplet of simples / of terminals or honours | 2 / 4 |
| Concealed triplet of simples / of terminals or honours | 4 / 8 |
| Open kan of simples / of terminals or honours | 8 / 16 |
| Concealed kan of simples / of terminals or honours | 16 / 32 |
| Open hand worth nothing else (open pinfu) | counts as 30 fu |
A triplet that is completed by a winning discard counts as open, because the winning tile came from someone else. Sequences are worth no fu.
Limit hands
From 5 han on, fu no longer matter. Hands of 4 han 30 fu and 3 han 60 fu or more are rounded up to mangan. Thirteen han or more is worth the same as one yakuman, but it is a counted yakuman and does not stack with real yakuman.
| Han | Name | Non-dealer, ron | Dealer, ron | Non-dealer, tsumo |
|---|---|---|---|---|
| 5 | Mangan | 8,000 | 12,000 | 2,000/4,000 |
| 6–7 | Haneman | 12,000 | 18,000 | 3,000/6,000 |
| 8–10 | Baiman | 16,000 | 24,000 | 4,000/8,000 |
| 11–12 | Sanbaiman | 24,000 | 36,000 | 6,000/12,000 |
| 13+ | Yonbaiman | 32,000 | 48,000 | 8,000/16,000 |
| Yakuman | Yakuman | 32,000 | 48,000 | 8,000/16,000 |
Payment tables
Each cell shows the payment for a win by ron, then for a win by tsumo. For a non-dealer tsumo the numbers are what the other two players pay, then what the dealer pays. A dealer tsumo is paid by everyone. Amounts are rounded up to the next 100, and counters and riichi sticks are added on top.

Who pays
- Ron: the player who discarded the winning tile pays everything.
- Tsumo: each player pays their share. When a non-dealer wins, the dealer pays double a normal share.
- Counters: every continuance counter adds 300 points to a ron, or 100 points per payer to a tsumo.
- The winner also collects every riichi stick on the table.
Draws and noten payments
When a hand ends in a draw, players who are not tenpai pay 3,000 points in total to the tenpai players, split evenly. With one noten player, that player pays 3,000 and each of the three tenpai players receives 1,000. With two, each pays 1,500 and each tenpai player receives 1,500. With three, each pays 1,000 and the single tenpai player receives 3,000. Counters are not affected by this payment, and riichi sticks stay on the table for the next winner.
Worked examples
These results are calculated by the same code that scores hands in MyMahjong.
| Hand | Value | Payment |
|---|---|---|
| Closed hand, riichi, won on a discard (non-dealer) | 3 han 30 fu | 3,900 |
| The same hand won by self-draw | 4 han 20 fu | 1,300/2,600 |
| Dragon triplet, won on a discard (dealer) | 1 han 40 fu | 2,000 |
| Seven pairs with riichi and a dora | 7 han 25 fu | 12,000 |
Payments show ron, or the tsumo shares. For a non-dealer tsumo the first figure is what each non-dealer pays and the second is what the dealer pays.
