* Winning from a [[Tanki|tanki]], [[Kanchan|kanchan]], or [[Penchan|penchan]] wait is worth 2 fu. A pinfu hand must win from a [[Ryanmen|ryanmen]] wait, i.e., the final tile must complete a shuntsu that was completable on any side. | |||

A winning tile drawn from the wall is normally worth 2 fu. If the closed hand otherwise qualifies as pinfu, these 2 fu are waived. The hand is then scored at 20 fu and at least 2 han for [Menzen tsumo|menzen tsumo] and pinfu. Some rule variations may not allow waiving these fu and score such a hand as 30 fu, tsumo, without pinfu. Such variations are rare. | |||
