**[[Complex waits]] can also score pinfu if they | **[[Complex waits]] can also score pinfu if they could be interpreted as a ryanmen wait. A [[sanmenchan]] wait, such as {34567}, always counts as a ryanmen wait, because it can be interpreted as {34 + 567} (a ryanmen wait) or {345 + 67} (also a ryanmen wait). [[Ryantan]] counts only if you win by completing the sequence (e.g. a wait of {4555} only scores pinfu if you win with 3 or 6). | ||
By avoiding all excess sources of fu, you can score pinfu. Triplets and quads score at least 2 fu each. A yakuhai pair scores 2 fu. A non-ryanmen wait scores 2 fu. | |||
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.

When a hand wins with pinfu, these 2 fu are waived. Thus, a pinfu tsumo is worth 20 fu. Pinfu ''is'' allowed to score the 10 fu from winning from a closed [[ron]], though. | ||
