Faan to points
| Faan | Base points | Discarder pays | Each pays on self-draw |
|---|---|---|---|
| 0 | 1 | 3 | 1 |
| 1 | 2 | 6 | 2 |
| 2 | 4 | 12 | 4 |
| 3 | 8 | 24 | 8 |
| 4 | 16 | 48 | 16 |
| 5 | 32 | 96 | 32 |
| 6 | 64 | 192 | 64 |
| 7 | 128 | 384 | 128 |
| 8 | 256 | 768 | 256 |
The half-laak comparison uses base points 1, 2, 4, 8, 16, 24, 32, 48, 64, 96, 128. The discarder pays 4× the base; on self-draw, each opponent pays 2×. Its 3–10 faan payments match the cited HKMA table; the 0–2 rows are mathematical extensions, not wins allowed by that source’s 3-faan minimum. Special liability is not included.

- Choose the preset agreed for your table. Street Corner uses an 8-faan cap; the half-laak comparison uses a 10-faan cap and different payment multipliers.
- Enter the final faan, including any self-draw, flower and other bonuses already earned. Select discard win or self-draw to set the payment split.
- Read the winner’s gain and all three opponents’ changes. Positive points are received, negative points are paid; the four changes sum to zero. Faan above the preset cap uses the capped value.
3-faan example: the same hand, different payments
| Preset | Discard win | Self-draw |
|---|---|---|
| Street Corner | Discarder −24; winner +24 | Each opponent −8; winner +24 |
| Half-laak comparison | Discarder −32; winner +32 | Each opponent −16; winner +48 |
All four examples start with 3 final faan. They compare payment methods, not the faan gained by changing how a particular hand wins. In a discard win, the two uninvolved opponents pay 0.
Calculator questions
Does the calculator add 1 faan when I select self-draw?
No. Enter the final faan after all applicable bonuses. Here, self-draw only changes who pays and how much. Use the hand calculator first if you still need to work out the faan.
Why does the table include 0–2 faan?
These rows are mathematical extensions for tables with a lower agreed minimum. The cited HKMA rules require at least 3 faan. A points result does not mean a hand is eligible to win at your table.
Can I use the result as a currency amount or a liability ruling?
The result is in points. It does not convert stakes to currency or handle special liability, penalties or a running match ledger. Confirm your table’s payment rules before using the comparison.
