How fan translates to payout through root scoring
| Pattern | Description | Fan |
|---|---|---|
| 1 fan | Base multiplier | 1 |
| 2 fan | 2x base (doubled once) | 2 |
| 3 fan | 4x base (doubled twice) | 3 |
| 4 fan | 8x base (doubled three times) | 4 |
| 5 fan | 16x base (doubled four times) | 5 |
| 6 fan | 32x base (doubled five times) | 6 |
In Sichuan Bloody mahjong, fan values translate to multipliers using root scoring. Each additional fan after the first doubles the payout. 1 fan = 1x base, 2 fan = 2x, 3 fan = 4x, 4 fan = 8x. This exponential scaling makes high-fan hands dramatically more valuable.
