'''Haiteihai''' {{kana|海底牌}} is the very last tile that can be drawn from the regular wall. This is clearly indicated as the 15th tile left, counting the tiles of the dead wall including the [[dora|dora indicator]]. Typically, this tile resides as the lower of two tiles next to the back end of the dead wall. Earlier calls for [[kan]] may "alter" the designation of the last tile, as that same bottom tile gets shifted into the dead wall to maintain fourteen tiles after the [[rinshan]] draw. In some groups, the tile may physically be moved | '''Haiteihai''' {{kana|海底牌}} is the very last tile that can be drawn from the regular wall.

Likewise, the very last discard is called '''houteihai''' {{kana|河底牌}}, which is subject to the call of "ron" for the houtei raoyui yaku and nothing else. [[Naki|Tile calls]] of chii, pon, or kan cannot apply to it. | Likewise, the very last discard is called '''houteihai''' {{kana|河底牌}}, which is subject to the call of "ron" for the houtei raoyui yaku and nothing else.

A player cannot call a kan after drawing the last tile (either normally or as a result of a kan), because they would need to draw a rinshanpai and doing so would bring the dead wall down to 13 tiles. | A player cannot call a kan after drawing the last tile (either normally or as a result of a kan), because they would need to draw a rinshanpai and doing so would bring the dead wall down to 13 tiles. | ||

Haitei and houtei are mutually exclusive with each other, with [[chankan]], and with [[rinshan kaihou]] | Haitei and houtei are mutually exclusive with each other, with [[chankan]], and with [[rinshan kaihou]]. Each of these yaku requires the winning tile to come from a different location (the live wall, a tile added to make a [[shouminkan]], and the dead wall, respectively). Houtei cannot combine with [[mentsumo]] because it is only winnable via discards. | ||
As for [[ippatsu]], it is impossible for the player calling riichi to have the last discard occur within one turn, because there must be at least 4 tiles left in the live wall when calling riichi. If an intervening call was made, which might mean that the player calling riichi would not get another draw, that call alone would disqualify an ippatsu. It is possible, however, for a player to call riichi with exactly four tiles left in the live wall and subsequently get both ippatsu and haitei on their next draw. | As for [[ippatsu]], it is impossible for the player calling riichi to have the last discard occur within one turn, because there must be at least 4 tiles left in the live wall when calling riichi.

Like any hand, either yaku requires tenpai at the very last draw and/or discard to even have a chance of winning. | Like any hand, either yaku requires tenpai at the very last draw and/or discard to even have a chance of winning. At this point, the hand can be any hand, even an open hand. Haitei or houtei would qualify for yaku on each of their own right. | ||
== Meaning == | |||
The term '''haitei raoyue''' translates literally as "scooping up the reflection of the moon from the bottom of the sea." It is a figurative Chinese expression (sometimes used in Japanese as well) use to mean a futile task. '''houtei raoyui''' is a pun on this, translating literally as "catching fish from the bottom of the river." The kanji 河 is the term ''[[kawa]]'', meaning the discard pond. Hence houtei is a pun referring to both haitei, and the act of catching a fish from the bottom of the discard river. | |||
