In the end, a pinfu hand must win from a [[ | In the end, a pinfu hand must win from a [[ryanmen]] wait. In other words, the winning tile must complete an open [[shuntsu]] (sequence). Complex wait patterns that include a ryanmen wait, such as [[ryanmentan]], would also be eligible for pinfu. | ||
Complex waits may be subject to [[takame and yasume]]. For example, a [[ryantan|wait consisting of 4445]] can be interpreted as a pair + ryanmen wait (44 + 45) or a triplet and tanki wait (444 + 5). In this case, winning from a 3 or 6 would score as pinfu, but winning from a 5 would not score this yaku. | |||
As an exception, pinfu with [[mentsumo]] gains 0 fu from tsumo, or winning by self-draw. Normally, a winning tile drawn from the wall is worth 2 fu. In turn, the hand qualifies as pinfu, and 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. | As an exception, pinfu with [[mentsumo]] gains 0 fu from tsumo, or winning by self-draw. Normally, a winning tile drawn from the wall is worth 2 fu.
