Winning shapes
The 8-fan gate
Scoring a hand
- Confirm an allowed winning shape.
- Find every compatible pattern.
- Remove patterns excluded by a higher pattern.
- Add the remaining fan; a legal win needs at least 8.
Self-draw, last tiles, replacement tiles, robbed kongs, waits, seat wind, and round wind can change the total. Flower points are added after qualifying and do not count toward the 8-fan minimum.
