This yaku is usually presented as three groups of consecutive pairs. However, the rule interpretation views them as a two [[shuntsu|sequences]]. Potential acquisition of this yaku is best recognizable when five out of the six tiles are present in the hand. | This yaku is usually presented as three groups of consecutive pairs.

Iipeikou requires two sequences, and as a result is incompatible with [[sanshoku doukou]], [[toitoi]], [[honroutou]], [[chiitoitsu]], [[sanankou]], and [[sankantsu]], all of which require either at least three [[koutsu]]/[[kantsu]] or a seven pair structure. The final incompatibility is with [[ryanpeikou]], as ryanpeikou implies iipeikou and so iipeikou is not counted. | Iipeikou requires two sequences, and as a result is incompatible with [[sanshoku doukou]], [[toitoi]], [[honroutou]], [[chiitoitsu]], [[sanankou]], and [[sankantsu]], all of which require either at least three [[koutsu]]/[[kantsu]] or a seven pair structure.

Iipeikou is often combined with [[pinfu]], which also requires sequences. Iipeikou can naturally be obtained with shapes like 4456 and 4556, which a pinfu hand may have due to [[tile efficiency]] reasons. | |||
