What is Sanbaiman?
Sanbaiman (三倍満) is a scoring tier in mahjong, achieved with 11 or 12 han. The name means “triple mangan,” with parent scoring 36,000 points and child scoring 24,000 points - the second highest tier after yakuman.
Sanbaiman represents nearly the limit of what can be achieved through normal yaku combinations, with tremendous impact when achieved.
