Riichi Mahjong Scoring
Every winning hand in riichi mahjong is scored using two values: han and fu.
- Han come from the yaku (winning conditions) in your hand and any dora.
- Fu adds texture to smaller hands. Fu is based on the specific shape of your hand and how you won.
If your hand has 5 or more han, the score is determined by han alone.

Han
Han are the primary unit of hand value. They are earned through circumstances (such as the timing or source of your winning tile) or through specific patterns of tiles in your hand.
Each yaku is worth a set number of han, and a hand can combine multiple yaku. Dora tiles also add han, but they are not yaku on their own — your hand must have at least one yaku to win.
Some yaku are worth fewer han (or are unavailable entirely) when your hand is open — that is, when you've called chi, pon, or kan. A × in the "Open" column means the yaku cannot be used with an open hand.

Fu
Fu are base points determined by the shape of your hand and how you won. To calculate fu, add up the values from the categories below, then round the total up to the nearest 10 (e.g. 32 fu → 40 fu).
Every hand starts with 20 fu.
| Tsumo (self-draw) | 2 |
| Ron, closed hand | 10 |
| Ron, open hand | 0 |
| Meld Type | Simples | Term / Hon |
|---|---|---|
| Sequence | 0 | 0 |
| Open triplet | 2 | 4 |
| Closed triplet | 4 | 8 |
| Open kan | 8 | 16 |
| Closed kan | 16 | 32 |
| Dragons / seat wind / round wind | 2 |
| Anything else | 0 |
| Two-sided (ryanmen) | 0 |
| Edge (penchan) | 2 |
| Closed (kanchan) | 2 |
| Single tile (tanki) | 2 |
| Pair (shanpon) | 0 |
① Base (20) + ② Win Method + ③ Melds + ④ Pair + ⑤ Wait
Round up to the nearest 10.
Exceptions
| Situation | Fu |
|---|---|
| Pinfu + tsumo — closed hand, all sequences, non-value pair, two-sided wait, won by self-draw | Fixed 20 fu |
| Chiitoitsu — seven pairs | Fixed 25 fu |
| Open hand with no fu (sometimes called kuipinfu) — an open hand that would otherwise be 20 fu (e.g. all sequences, ron) | Counted as 30 fu |
Limit Hands
When a hand reaches 5 or more han, fu no longer matter. The score jumps to a fixed amount based on the han count:
| Han | Name |
|---|---|
| 5 (or 3–4 han with enough fu) | Mangan |
| 6–7 | Haneman |
| 8–10 | Baiman |
| 11–12 | Sanbaiman |
| 13+ | Counted Yakuman |
Hands also reach mangan if they hit 4 han 30+ fu or 3 han 60+ fu. Use the payment calculator to look up the exact point values.
