'''Atozuke''' {{kana|後付け}} describes a "yakuless" [[tenpai]] 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}}. | '''Atozuke''' {{kana|後付け}} describes a "yakuless" [[tenpai]] which gains [[yaku]] upon winning.

When a hand is subject to atozuke, it may still win if it draws the "[[takame|higher value]]" tile. However, it is normally unable to win off the "[[yasume|lesser]]" tile, since it would lack yaku. If the lesser tile is drawn, the hand may be subject to [[furiten]]. | When a hand is subject to atozuke, it may still win if it draws the "[[takame|higher value]]" tile.

Note: as with any "yakuless" hand, a hand subject to atozuke may win from the lesser tile by gaining [[haitei]], [[houtei]], [[rinshan]], or [[chankan]]. Closed hands can also win by [[mentsumo]]. If a hand in atozuke does not gain one of these conditional yaku, though, it cannot win by the lesser tile. | |||

To repeat, atozuke is most often enabled. So such a hand can win under most rulesets without needing riichi. | |||

When atozuke is enabled, players may deliberately enter the state of atozuke, depending on the [[haipai|starting hand]]. Calling tiles helps [[tile efficiency|develop the hand faster]], even if there's a chance you may not win later. For example, with a [[yakuhai]] pair, you may want to call early and hope someone discards the needed yakuhai later. | |||
