|Tile types waiting||3 sided wait|
|Tiles available||7 tiles|
Example: Not entotsu
If a 10-man tile exists, then this would be entotsu; but of course, that is not the case.
This tile pattern does not reward fu on its own. Instead, fu is earned via the composition of the triplet. Regardless of the winning tile, the pattern guarantees one triplet.
The wait pattern can be doubled, such that it occurs into one hand. Essentially, they can be viewed as a pair of ryanmen. However, this pattern is not possible without the entotsu patterns.
