Pinfu (平和) is a standard yaku. This yaku is defined by having 0 fu aside from the base 20 fu, or 30 fu in the case of a closed ron. It is worth 1 han and closed only.

The winning tile completes the last sequence, which is worth 0 fu, making the hand pinfu.
English reference
In English, pinfu is sometimes referred to as "all sequences". However, the yaku is not as simple as that. Other than having an open hand, it is possible for a hand to be composed of all sequences and still not be classed as a pinfu. The following examples are a "all sequence hands"; but they are not pinfu.

The first and third examples can be pinfu. In the case of the first example, the hand must be formed during the south round, while not seated as east. For the third example, the hand is pinfu for all players not seated north. As for the second and fourth examples, under no circumstances can they be pinfu.
Fu
To understand pinfu, players must understand the nature of fu. Fu are a set of points associated with hand composition. Pinfu lacks any fu except the 10 menzen-kafu for winning with a closed ron.
- Any koutsu or kantsu is worth at least 2 fu. A pinfu hand must have four shuntsu.
- Winning from a tanki, kanchan, or penchan wait is worth 2 fu. A pinfu hand must win from a ryanmen wait, i.e., the final tile must complete a shuntsu that was completable on any side.
- A pair of yakuhai, i.e., dragons, the round wind, or the seat wind, is worth 2 fu. A pinfu hand must have a valueless pair.
- An open hand worth 20 fu is counted as 30 fu. Pinfu may only be awarded to a closed hand.
In the end, a pinfu tenpai hand must have a wait of either a ryanmen or ryanmenten.
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 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.

Essentially, pinfu is incompatible with any yaku that employs triplets. On the other hand, pinfu works any sequential based yaku. As long as the hand is closed, the pair does not produce "fu", and the wait is open, then pinfu may be applied.
