Key Rules & Scoring Principles
1. Minimum Points to Win (和牌)
- A winning hand must total at least 8 points (番).
- Points are multiplicative, not additive (e.g., two 4-point patterns = 8 points total).
2. Common Scoring Patterns (番种)
| Points (番) | Pattern Name (English/Chinese) | Description |
|----------------|-----------------------------------|----------------|
| 88 | 大四喜 (Big Four Winds) | Four sets of Winds (东/南/西/北). |
| 88 | 大三元 (Big Three Dragons) | Three sets of Dragons (中/发/白). |
| 64 | 十三幺 (Thirteen Orphans) | One of each terminal/honor tile plus any duplicate. |
| 32 | 七对 (Seven Pairs) | Seven pairs (no melds). |
| 24 | 清一色 (Pure One Suit) | All tiles in one suit (no honors). |
| 12 | 全不靠 (No Connections) | Hand with 14 unique tiles (specific arrangement). |
| 8 | 混一色 (Mixed One Suit) | One suit + honor tiles. |
| 6 | 碰碰和 (All Pungs) | Four melds of Pungs/Kongs + a pair. |
| 4 | 平和 (All Chows) | Four Chows + a pair (no Pungs). |
| 2 | 断幺九 (No Terminals/Honors) | No 1/9 or honor tiles. |
| 1 | 花牌 (Flower Tiles) | Bonus for matching seat/wind flowers. |
3. Special Multipliers
- 自摸 (Self-Draw): +1 point (but doesn’t count toward the 8-point minimum).
- 杠上开花 (Kong Draw): Win by drawing after a Kong.
- 海底捞月 (Last Tile Draw): Win with the final wall tile.
4. Penalties
- 诈和 (False Win): Pay each player the max possible points (e.g., 88).
Basic Gameplay Flow
1. Deal: 13 tiles per player; draw to 14 to win.
2. Winning (和牌): Form 4 melds + 1 pair (or special patterns like Seven Pairs).
3. Scoring: Calculate points from all applicable patterns.
Example Hand
- Tiles: 3x East Wind (东), 3x South Wind (南), 3x West Wind (西), 3x North Wind (北), 1-2 of Bamboos (pair).
- Patterns: Big Four Winds (88) + Seat Wind (2) = 90 points.
