'''Kuisagari''' {{kana|喰い下がり}} is a property of some yaku to lose value when [[naki|called open]].  When calling on a discard and opening the hand, a player sacrifices the value of 1-han per yaku affected by this rule. The loss in value is obviously bad, though calling allows you to develop your hand faster. If certain tiles are discarded, a player may need to make the open call, or not score the yaku at all. If the hand is valuable enough (e.g. from having [[dora]]), the loss of value can be deemed worthwhile.  

Similarly, some yaku can only be scored with a closed hand. Certain yaku, like [[chiitoitsu]] and [[mentsumo]], are closed based on their structure or nature. Other yaku, like [iipeikou]], the requirement of a closed hand is entirely artificial. Unlike instances of kuisagari, you cannot use these yaku to fulfill the yaku requirement of an open hand: these are not considered 0 han yaku. For [[ryanpeikou]] in particular, if it were affected by kuisagari, it would score 2 han when opened. In actuality, you cannot achieve ryanpeikou at all with an open hand.

A side effect to kuisagari involves '''atozuke'''.  Tile calls may put a hand into position where one of its waiting tiles do not produce valid yaku.  With this in mind, tile calls must be made with careful discretion.
