Atozuke: Difference between revisions

'''Atozuke''' {{kana|後付け}} describes a "yakuless" [[tenpai]] hand which gains [[yaku]] upon winning. In other words, the current state of the hand does not produce yaku while tenpai. This typically involves an open hand, but can also apply to closed hands without [[riichi]]. It is also called '''sakizuke''' {{kana|先付け}}.

When a hand is subject to atozuke, it may win if it draws the [[takame|higher value]] tile. However, it is usually unable to win off the [[yasume|lesser]] tile, since it would lack yaku. Such hands may still win with the lesser tile if it gains a conditional yaku (like [[haitei]] or [[rinshan]]) - otherwise, it cannot win. Thus, if the lesser tile is drawn, the hand may be subject to [[furiten]].

Atozuke is subject to [[Rule variations#Atozuke|rule variations]]. When the atozuke rule is disabled ("atozuke nashi"), you must have a confirmed yaku before winning (and sometimes, before making any call). The more common rule, by far, is to allow atozuke. Rules disabling atozuke are rare, mostly found in specific [[jansou|mahjong parlor]]s.
