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 having a closed hand that avoids all extra 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, though it gains +1 han from [[menzen tsumo]].

Thus, a pinfu tsumo is worth 20 fu, and is the only hand that can be worth 20 fu. (Open hands with 0 fu gain +2 fu for being open.)

*Riichi + Mentsumo + Tanyao (3 han 30 fu) = 4000 points
*Riichi + Mentsumo + Tanyao (3 han 30 fu) = 4000 points


Of course, pinfu still increases your score (riichi + tanyao + pinfu is worth more than riichi + tanyao). Once the hand reaches [[mangan]] or higher, fu no longer matter, so pinfu is worth the same as any other 1-han yaku.
Of course, pinfu still increases your score even with the fu decrease (riichi + tanyao + pinfu > riichi + tanyao). Also, once the hand reaches [[mangan]] or higher, fu no longer matter, so pinfu is worth the same as any other 1-han yaku.
 
(If an open hand would have qualified for pinfu if it were closed, it is bumped up to 30 fu.)
