|English||Two sets of identical sequences|
|Value||3 han (closed only)|
This yaku does not combine with chiitoitsu. By definition, chiitoitsu is formed by the collection of seven pairs. At every instance, ryanpeikou hands look like chiitoitsu hands. However, ryanpeikou is actually composed of sequences, rather than as independent pairs. The pattern simply appears as a collection of pairs. Because of this interpretation, the two yaku remain distinct and incompatible; and it is doubtful, that any house rule allows the combination of the two yaku.
Closed only, ryanpeikou is always at 3 han. So, there is no need to be concerned about a lesser value of the hand while open, or kuisagari. The cheapest ryanpeikou hand uses either a kanchan (closed) or tanki (pair) wait. In both cases, the hand produces a 3-han and 40-fu value by ron. By tsumo, it is 3-han and 30-fu.
