Complex waits
These machi involve waits which are infrequent and generally nameless combinations. They are all based on combinations of other basic machi, often in many differnet ways. Often, they consist of consecutive, or closely consecutive, numbered tiles. Recognition of these patterns can produce some significantly powerful waits, which may be immune to suji and have large numbers of waiting tiles. This list is not exhaustive and not every possible waiting pattern is included.

This pattern is notable because it has 23 winning tiles, like the chuuren poutou kyuumen machi, but unlike most other hands waiting on 23 tiles, it cannot completed by a hypothetical fifth copy of any tile (a 3m or a 7m would not complete this hand).
