Complex waits
These patterns involve waits which are infrequent and generally nameless combinations. They are all based on combinations of other basic wait patterns, often in many different ways. 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.
