'''Nakabukure''' {{kana|中膨れ}} is a type of pair wait. Here, the middle tile is duplicated in a [[shuntsu|sequence]], and the hand waits on said tile. With two of the tiles already in the hand, this gives the wait one less tile to wait for compared to a regular tanki.  An alternate term, '''harabote''' {{kana|腹ボテ}}, may be used, but it is also an inappropriate term.

By default, the tanki wait counts for 2 [[fu]].
*If the pair happens consist of [[yakuhai]] tiles, then an additional 2 fu is added for said pair.
*If the pair is both the [[round wind]] and your [[seat wind]], it may - [[Scoring_variations#Double_wind_fu|depending on the ruleset]] - adds 4 fu instead of the usual 2 fu for yakuhai.
[[Chiitoitsu]] hands always have a total of 25 fu, regardless of their wait, types of pairs, or winning type.
==Multi-sided Tanki==
These [[complex waits]] are composed partially or entirely of tanki waits.

A [[nobetan]], if kept until tenpai, is a two-sided tanki wait. The hand waits to complete a pair, but two types of tiles are eligible to complete the pair, because the to-be-paired tile is next to a sequence. If a 3p is drawn, you are left with a 3p pair and 456p sequence. If a 6p is drawn, you are left with a 345p sequence and 6p pair.

'''Sanmen nobetan'''

Sanmen nobetan is a three-sided tanki wait. It works like a nobetan, but attached to two sequences instead of one sequence.

A [[ryanmen]] wait attached to the hand's pair. When winning with the 6p, this hand can be interpreted as either {66 + 78} (a ryanmen wait) or {6 + 678} (a tanki wait). The interpretation that would result in the most final points is used. When winning with 9p, the other side of the ryanmen, the hand can only be interpreted as having a ryanmen wait.
 
===Ryantan, Kantan, & Pentan===
{{main|Ryantan|Kantan|Pentan}}
 
These three wait patterns can all be described as "a triplet with one adjacent tile attached". They are combinations of tanki and another type of basic wait.
 
'''[[Ryantan]]''' (Ryanmen + Tanki) - Triplet with a tile that is numerically adjacent, and neither the triplet or the extra tile are a terminal tile. This can be interpreted as "33 + 34" or "333 + 5", thus waiting on 3 types of tiles (2 or 5 or 4). This wait is worth fu only if it wins off the lone tile (in this case, the 4).
 
{{#mjt:000z3334p000000z}}
 
'''[[Kantan]]''' (Kanchan + Tanki) - Triplet with a tile that is numerically 2 away. This can be interpreted as "33 + 35" or "333 + 5", thus waiting on 2 types of tiles (4 or 5). 
 
{{#mjt:000z3335p000000z}}
 
'''[[Pentan]]''' (Penchan + Tanki) - Triplet with a tile that is numerically adjacent, and at least one tile is a terminal. This can be interpreted as "11 + 12" or "111 + 2", thus waiting on 2 types of tiles (2 or 3).


[[Chiitoitsu]] hands always have a total of 25 fu, regardless of their wait, types of pairs, or winning type.
