There is only one formula
Base points are fu × 2^(2+han), capped at 2000. A non-dealer ron collects base ×4, a dealer ron ×6, rounded up to the nearest hundred. On tsumo a non-dealer takes ×2 from the dealer and ×1 from each other; a dealer tsumo takes ×2 from all three. The charts below are just this formula, pre-computed.
Ron chart (non-dealer / dealer)
Two anchors worth memorising: 30 fu 1 han is 1000 for a non-dealer, and 30 fu 4 han is the famous 7700. At 40 fu 4 han most rules round up to mangan.
| Fu | 1 han | 2 han | 3 han | 4 han |
|---|---|---|---|---|
| 25 | — | 1600 / 2400 | 3200 / 4800 | 6400 / 9600 |
| 30 | 1000 / 1500 | 2000 / 2900 | 3900 / 5800 | 7700 / 11600 |
| 40 | 1300 / 2000 | 2600 / 3900 | 5200 / 7700 | 8000 / 12000 |
Tsumo chart (non-dealer / dealer)
Notation: “300·500” means the two other non-dealers pay 300 each and the dealer pays 500; “500 all” is a dealer tsumo with everyone paying 500. 20 fu only exists as pinfu tsumo.
| Fu | 1 han | 2 han | 3 han | 4 han |
|---|---|---|---|---|
| 20 | — | 400·700 / 700all | 700·1300 / 1300all | 1300·2600 / 2600all |
| 25 | — | — | 800·1600 / 1600all | 1600·3200 / 3200all |
| 30 | 300·500 / 500all | 500·1000 / 1000all | 1000·2000 / 2000all | 2000·3900 / 3900all |
From five han fu stops mattering
From five han upward the payment is a fixed value — which is why the fu field disappears past four han in the scorekeeper.
| Name | Han | Non-dealer / dealer |
|---|---|---|
| 満貫 | 5 | 8000 / 12000 |
| 跳満 | 6–7 | 12000 / 18000 |
| 倍満 | 8–10 | 16000 / 24000 |
| 三倍満 | 11–12 | 24000 / 36000 |
| 役満 | 13+ | 32000 / 48000 |
Honba, sticks and draws
Each honba adds 300 to a ron, or 100 from each player on tsumo. Riichi sticks are 1000 apiece and the winner sweeps every stick on the table. The 3000-point draw payment splits by tenpai count: one player takes 3000, two take 1500 each, three take 1000 each.
You can memorise all of this — or open the riichi scorekeeper on Tallyo, pick han and fu, and get the payment instantly, with dealer repeats, honba, sticks and the final uma/oka settlement all tracked for you.
