Tatsumaki 「竜巻」 is a tile wait pattern that uses a combination of ryanmen, shanpon, and tanki waits to create a hand waiting on 5 consecutive tiles in the same suit. This is a particularly powerful waiting pattern as it relies on only seven tiles in the concealed portion of the hand, so even with two called tile groups, the hand can have a 5-sided wait.
Pattern
Waiting for: 
The pattern is always composed of two sets of numbered triplets, where the triplets are 2 ranks apart (such as triplets of 4 and 6). The two sets of triplets are connected by a single numbered tile in-between the two numbers. The pattern can be created with a terminal triplet, though the waits will be reduced.
This pattern can be considered the combination of 2 ryantan waits:
- + ; waiting for
- + ; waiting for
Unlike ryantan, winning with 4 or 6 can be considered a shanpon wait instead of a ryanmen wait.
Fu
This pattern generates 2 fu for a tanki wait only if it is won with the middle tile. Winning with any of the four other tiles will not give any fu directly, as it will be interpreted as either a ryanmen wait or shanpon wait.
