Scoring
Fu

Han
There is no kandora or uradora.
A special rule of zoroba 「ゾロ場」 is used:
- Each 1 or 6 rolled during the deal adds 1 han to the winning hand.
- Each sum of 7 also adds 1 han to the winning hand.
- If neither of the conditions are met, the dice are rolled again until at least 1 han is added. Each reroll adds 300 points to the winning hand, similar to honba.
- Zoroba does not count towards the 1 han minimum.
