**[[Complex wait]]s can score pinfu if they are composed off of ryanmen waits. Therefore, a [[sanmenchan]] wait always counts. [[Ryantan]] counts if you win by completing the sequence (e.g. a wait of {4555} only scores pinfu if you win with 3 or 6). | **[[Complex wait]]s can score pinfu if they are composed off of ryanmen waits.

If you know | If you know how fu is scored, the requirements for pinfu make sense. Triplets and quads score at least 2 fu each. A yakuhai pair scores 2 fu. A non-ryanmen wait scores 2 fu. Therefore, by avoiding these sources of fu, you gain pinfu. Pinfu ''is'' allowed to score the 10 fu from winning from a closed [[ron]]. | ||
As an exception, pinfu does not score fu from [[tsumo]] (win from self draw). Normally, a win by self draw is worth 2 fu. When a hand wins with pinfu, these 2 fu are waived. Thus, a pinfu tsumo is worth 20 fu, but gains +1 han from [[menzen tsumo]]. | As an exception, pinfu does not score fu from [[tsumo]] (win from self draw). Normally, a win by self draw is worth 2 fu.

Pinfu is one of the most common yaku. When developing a hand, players will naturally keep [[ryanmen]] shapes in their hand, due to their higher [[tile efficiency]]. In addition, sequences are easier to complete than triplets. While it isn't as fast as [[tanyao]] or [[yakuhai]], as pinfu cannot be scored open, this yaku is still seen often. It naturally combines with other sequence based yaku, namely [[iipeikou]], [[sanshoku doujun]], and [[ittsuu]]. | Pinfu is one of the most common yaku.
