'''Aryanmen''' {{kana|亜両面}} is a variation on the [[ryanmen]] [[machi|waiting pattern]]. Appearing as a complete sequence with one extra tile on either end, it can either be interpreted as "a ryanmen next to the hand's pair" or "a complete sequence with a [[tanki]] wait". Aryanmen is generally weaker than ryanmen, since 2 of the 8 winning tiles are in the hand, though it is better than tanki if a hand needs a pair. | '''Aryanmen''' {{kana|亜両面}} is a variation on the [[ryanmen]] [[machi|waiting pattern]].

When aryanmen is won with the waiting tile already present in hand, it can be interpreted as either a tanki or ryanmen wait. In this case, the highest-scoring option must be chosen. Normally, this will be the 2 fu for a tanki wait, but if the hand qualifies for the [[pinfu]] [[yaku]], that will be scored instead. | When aryanmen is won with the waiting tile already present in hand, it can be interpreted as either a tanki or ryanmen wait.

== Formation == | |||
If the hand currently lacks a pair, aryanmen is a relatively easy way to form a 2-sided wait. For each complete sequence you have, there will be 2 types of tile you can draw to form an aryanmen (and another 1-2 types that can form a [[nobetan]]). This can help with [[pinfu]], which aryanmen counts for. However, aryanmen is weaker than ryanmen, since the tile acceptance is only 6 instead of 8. | |||
[[Ryantan]], [[kantan]], and [[pentan]] can be formed in a similar way - by drawing an adjacent tile next to a triplet, you have a 2/3-sided wait for a pair. | |||
