[[Complex waits]] can always be split into multiple types of basic wait. For example, a 23456 [[sanmentan]] can be considered as either as {23} wait or a {56} wait. Both these are ryanmen, so a sanmentan is considered a type of ryanmen wait. Other examples: | |||
*A [[nobetan]] can be counted as two individual tanki waits, so it always scores 2 fu from tanki. | |||
*A [[ryantan]] counts as ryanmen if it wins by completing the sequence, and a tanki if it wins by completing the pair. | |||
*A [[pentan]] counts as penchan if it wins by completing the sequence, and a tanki if it wins by completing the pair. Since penchan and tanki are worth the same fu, there isn't a practical difference between the two. | |||
*An [[ayranmen]], like 6788-pin, is always counted as a ryanmen if it wins off a 5-pin. If it wins off the 8-pin, however, it may be counted as a ryanmen or as a tanki. The interpretation with the highest score is used (see below for details). | |||
