Rinshan kaihou: Difference between revisions

When calling kan, a player must draw an extra tile; and that tile comes from the dead wall.  This is the '''rinshanpai''' {{kana|嶺上牌}}.  If the hand is completed with this tile draw, then this yaku is awarded.  It is quite possible for rinshan to be the only yaku for the hand.  Usually, players already have other yaku.

Rinshan kaihou is generally compatible with any hand, that can accommodate kan calls. This rules out any yaku dependent on all sequential tile groups, namely both [[pinfu]] and [[ryanpeikou]].  Other yaku, such as [[sanshoku]] and [[ittsu]], are also sequential based, but they have room one triple tile group to be upgraded for a kan call.  By definition, [[chiitoitsu]] requires every [[toitsu|tile pair]] to be unique; so kan calls cannot be performed here.  [[chankan]], [[haitei]], and [[houtei]] all require winning from a different location than a kan replacement tile (another player's kan, the live wall, and another player's discard, respectively) and so cannot combine with rinshan. Finally, a kan would interrupt a chance for [[ippatsu]].
