Fan
Fan add up, and each fan doubles the payment. Hand patterns and bonus fan, with examples.
What fan are
When you win, add up the fan of every pattern in your hand. Each fan doubles what you collect: 0 fan collects 1 base, 1 fan collects 2, 2 fan collects 4. Anything above the cap (4 fan by default) counts as the cap.
Hand patterns
| Hand | Fan |
|---|---|
| Plain hand (平胡)A complete hand with no other pattern. | 0 |
| All pungs (對對胡)All four sets are pungs or kongs. | 1 |

Common combinations
Patterns stack:
Roots
For every tile kind where all four copies are in your hand (four in hand, or a kong), add 1 fan.
In dragon seven pairs the four of a kind is already counted, so it is not a root again — only a second set of four adds one.
Bonus fan
How you win can add fan too:
| Bonus fan | Fan |
|---|---|
| Win after a kong (槓上開花)Self-draw on the replacement tile after a kong. | 1 |
| Deal-in after a kong (槓上炮)Winning on the discard a player makes right after a kong. | 1 |
| Robbing a kong (搶槓胡)Winning on the tile someone adds to a pung. | 1 |
| Last-tile self-draw (海底撈月)Self-draw on the very last tile of the wall. | 1 |
| Last-tile discard (海底炮)Winning on the discard after the last tile is drawn. | 1 |
| Self-draw bonus (自摸加番)Only with the “+1 fan” self-draw rule. | 1 |
| Heavenly hand (天胡)The dealer is complete before the first discard. | Cap |
| Earthly hand (地胡)Self-draw on your very first draw, with no calls before it. | Cap |
Heavenly and earthly hands go straight to the cap.
