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.

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. | ||

# The hand must have a specific yaku confirmed before winning and before calling any tile. Therefore, a hand that could always win with atozuke enabled may not be allowed to win. | |||
# The hand must have a yaku no matter which tile it wins on. Any hand that always has a yaku can win. | |||

Similarly, when rule #2 is used, this hand can win. | ||
But when rule #1 is used, this hand cannot win. Neither iipeikou nor sanshoku are confirmed. Because this hand does not ''guarantee'' "iipeikou", "sanshoku", or any other specific yaku in its current state, it cannot win. (Of course, since this is a closed hand, you can just call [[riichi]].) | |||

Therefore, this hand cannot win when rule #1 is in effect. Note: for whole hand yaku, like [[honitsu]], the yaku can be scored even if the yaku wasn't complete at the time of calling. Similarly, calling for [[chanta]]/[[junchan]] is allowed so long as your final wait guarantees the yaku. | ||
