-'''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]].  Along with [[tanyao]] and [[riichi]], these yaku are the easiest and most frequently occurring yaku in the game. [[Sangenpai|Dragon tile groups]] always count for yakuhai. [[Kazehai|Wind tiles]] only count for yakuhai if they are the [[round wind]] or the player's [[seat wind]]; other winds are considered offwind or '''otakaze''' {{kana|客風}} and do not grant a yaku or any han, though they may still form valid triplets for the purpose of making four sets and a pair for a complete hand.
+'''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"; these are not yakuhai and not worth any han, but are still valid tile groups to complete the "4 groups + 1 pair" shape.
+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.
-==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 also 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]].

 {{Yaku compatibility table|YAK}}
-Yakuhai essentially works with any yaku which has room or allows the use of honor tile groups, which gives it great versatility.  [[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.
+Yakuhai is compatible with any yaku which allows a triplet and allows honor tiles. [[Tanyao]], [[junchan]], and [[chinitsu]] forbid honor tiles. [[Pinfu]] and [[ryanpeikou]] do not allow triplets. [[Chiitoitsu]] requires seven distinct pairs, also preventing triplets.

-Incompatibilities arise for a few reasons. Firstly, the definitions of [[tanyao]], [[junchan]], and [[chinitsu]] eliminates the use of honor tiles all together. [[Pinfu]] and [[ryanpeikou]] each require four sequence groups and [[chiitoitsu]] requires seven distinct pairs, leaving no room for a triplet in any of these yaku.
+Hands that are opened before confirming a yakuhai triplet are particularly subject to [[atozuke]]. Here, the hand depends on yakuhai to gain a yaku. Under normal circumstances, this hand may win if it obtains the hatsu, but not the 9-man. (It can win with any winning tile if a conditional yaku, such as [[houtei]] or [[chankan]], is obtained.)
