# The hand must have a specific yaku confirmed before winning. In addition, when calling, it must have a specific yaku confirmed without needing to make another call and without needing the winning tile. (In most cases, this is equivalent to "you must confirm a yaku when you make the first call".) | # The hand must have a specific yaku confirmed before winning.

:* When a yaku is not guaranteed because it is implied by a superior yaku, e.g. when a hand can score either [[sanankou]] or [[suuankou]], atozuke doesn't apply. | |||
:* Yaku with requirements on the whole hand, such as [[honitsu]] and [[chanta]], are immune to atozuke so long as the final wait confirms the yaku. | |||
# The hand must have a yaku no matter which tile it wins on. Any hand that always has a yaku (any yaku) by the end can win. | # The hand must have a yaku no matter which tile it wins on. Any hand that always has a yaku (any yaku) by the end can win. | ||

But when rule #1 is used, this hand cannot win. Iipeikou is not guaranteed, neither is sanshoku. Because the hand cannot guarantee any specific type of yaku in its current state, it cannot win. In this case, the hand is closed, so you just can call [[riichi]]. | But when rule #1 is used, this hand cannot win. Iipeikou is not guaranteed, neither is sanshoku.

When the hand's ''closed section'' guarantees a specific yaku, and the winning tile is not related to completing said yaku, the hand is never subject to atozuke. Even under rule #1, it will always be eligible to win. | When the hand's ''closed section'' guarantees a specific yaku, and the winning tile is not related to completing said yaku, the hand is never subject to atozuke.

In this case, the hand has a closed hatsu triplet, so it can always win. Even if the hatsu triplet was drawn after the 789-sou call, there would be no practical way to prove you didn't have the hatsu triplet before calling. Therefore, "drawing into a yaku after calling" is allowed so long as you complete the yaku before tenpai. | |||
