Baiman

Baiman is the Riichi limit tier above haneman, covering hands worth 8, 9, or 10 han. It pays double a mangan: 16,000 points for a non-dealer and 24,000 for a dealer. On a self-draw the total is split among the other players, 4,000 from each non-dealer for a non-dealer baiman, or 8,000 from each when the dealer wins by tsumo.

As with the other limit tiers, baiman is a flat band: an 8-han hand and a 10-han hand both pay the same baiman amount, and fu is irrelevant once a hand reaches this range. Hands typically arrive at baiman by combining a heavy yaku with substantial dora, for example a closed full flush (chinitsu, 6 han) plus several dora and akadora, or a honitsu hand stacked with ura dora after a riichi win.

Baiman sits between haneman (6-7 han) below and sanbaiman (11-12 han) above in the ladder of Riichi limit hands, which culminates in yakuman at 13+ han or a recognized special pattern. The discrete tiers mean that adding even one more han to an 8-han hand does nothing until 11 han is reached, so players evaluate jumps carefully.

Baiman is unique to Riichi and Japanese-derived scoring; other variants use their own caps and terminology. As an example, a closed chinitsu hand worth 6 han with two dora and two ura dora revealed after riichi totals 10 han, paying a non-dealer baiman of 16,000 points.
