How to calculate your hand’s faan
- Add the concealed tiles, including the winning tile. Put declared Chows, Pungs and Kongs in Melds. A Kong has four physical tiles but occupies one meld: the concealed count is 14 minus 3 per declared meld.
- Choose the winning method and minimum, then check seat wind, round wind and winning tile. Add only the flowers actually received. No extra faan is awarded simply for having no flowers under this house ruleset.
- Read shape eligibility first, then the itemised faan, total before the cap and final faan. A complete hand can still fall below the minimum. Eligible house hands link directly to their points calculation.
Try six hands with explained results
These are house-rule examples: all concealed, won on a discard, with no selected flowers. The final total includes other applicable items. Little Three Dragons includes both dragon pungs in its 5 faan; Thirteen Orphans is the house 8-faan limit.
| Hand guide | House pattern faan | Saved example total |
|---|---|---|
| All Chows | 1 | 2faan · Try it → |
| All Pungs | 3 | 5faan · Try it → |
| Half Flush | 3 | 5faan · Try it → |
| Full Flush | 7 | 8faan · Try it → |
| Little Three Dragons | 5 | 6faan · Try it → |
| Thirteen Orphans | 8 | 8faan · Try it → |
For All Pungs and Half Flush, the saved total is 3 + 1 for a dragon pung + 1 for a concealed hand. All Chows totals 2 and does not meet the default 3-faan minimum. Full Flush totals 7 + 1; Little Three Dragons totals 5 + 1.
Calculator questions
Why is a complete hand still below the minimum?
A winning shape and enough faan are separate checks. The All Chows example has 1 faan for the pattern and 1 for a concealed hand under our house rules. Its 2-faan total falls short of the default 3-faan minimum.
Can I use this as an HKMA rules calculator?
The automatic check uses Street Corner house rules. Important differences include the pair allowed for All Chows, concealed-hand bonuses and the limit for Thirteen Orphans. Custom mode adjusts the house total manually; it does not implement another complete ruleset or recognise new hand shapes.
Does changing the winning method change the faan?
Yes, the hand calculator checks self-draw and any compatible winning circumstances as part of the faan breakdown. Limit hands do not add ordinary bonuses. The separate score calculator expects the final faan and does not add these bonuses again.
