'''Yakuhai''' {{kana|役牌}}, or '''Fanpai''' {{kana|飜牌}}, is a group of 1 [[han]] [[yaku]] scored for completing a [[mentsu|group]] of [[jihai|honor tiles]]. | '''Yakuhai''' {{kana|役牌}}, or '''Fanpai''' {{kana|飜牌}}, is a group of 1 [[han]] [[yaku]] scored for completing a [[mentsu|group]] of [[jihai|honor tiles]]. They come in three classes: | ||
* [[Sangenpai|Dragon tile groups]] always count for yakuhai. | |||
* [[Kazehai|Wind tiles]] of the [[round wind]] count as yakuhai. | |||
* Wind tiles of the [[seat wind]] also count as yakuhai. | |||
If a wind is both the round and seat wind, it is worth 2 han. A wind that is neither round or seat wind is known as an "offwind" ({{kana|客風}}) or "guest wind"; they are not yakuhai and not worth any hand, but are still valid tile groups. | |||
The yakuhai as a whole, along with [[riichi]] and [[tanyao]], are some of the easiest and most frequent yaku in the game. | |||

Each of the dragon quads scores 1 han for its own yakuhai. They are scored separately, and the fact that they are quads rather than triplets is irrelevant in the scoring. The additional [[jantou|pair]] of red dragons means that the hand scores [[shousangen]] in addition to, but not instead of, the double yakuhai. | Each of the dragon quads scores 1 han for its own yakuhai.

[[Honitsu]] is one of the most effective combinations with at least one yakuhai group. This yaku is compatible with itself. Different groups of yakuhai tiles may be collected into one hand; and in turn, they are treated as separate yaku, despite identical functionality. In particular, [[shousangen]] requires not just one, but two yakuhai. | [[Honitsu]] is one of the most effective combinations with at least one yakuhai group. This yaku is compatible with itself.

==Usage== | |||
Along with [[tanyao]], yakuhai are among the easiest yaku to learn and use. As the honour tiles are generally weak due to their inability to form [[shuntsu|sequences]], they are often discarded early in the hand. A player starting with a [[toitsu|pair]] of eligible tiles can usually [[pon]] a third, instantly satisfying the yaku requirement. This ability makes this yaku exceptionally convenient for the completion of fast hands. Therefore, this yaku is sometimes called an '''express ticket'''. | |||
Players looking for a quick win will often hold lone yakuhai tiles a little longer than their [[tile efficiency]] would dictate, in hopes of getting a second and then calling (or drawing) a third to make a yakuhai. This is particularly true with hands that will have difficulty completing an open [[tanyao]], either because they have lots of [[routouhai|terminals]] or honours, or because [[kuitan|open tanyao]] is not allowed. | |||

Yakuhai hands may commonly be used for [[atozuke]]. Here, the hand depends on yakuhai for yaku, where among the multiple waiting tiles, one of them is a yakuhai tile. However, the other waiting tile(s) may not produce a yaku, unless it wins via [[chankan]], [[rinshan]], [[haitei]], or [[houtei]]. | |||
