==Basic wait patterns==
==Basic wait patterns==
There are five '''basic wait patterns'''. These are made out of 1 or 2 tiles. Upon tenpai, they only look to complete either the last tile group or the pair. All waits can be derived from the basic waits.

Each of these wait patterns are worth a set amount of [[fu]]. For the purposes of fu counting, a complex wait can always be interpreted as one of the basic waits. (If multiple interpretations are possible, the highest scoring one is used. This may or may not be the one with the most fu.)

Assuming all else equal, ryanmen is the strongest of the basic wait patterns, with twice the number of tiles as the others. Shanpon is stronger than the others, since waiting on 2 types of tile is better than 1, and shanpon can wait with [[honor]] tiles. Kanchan and penchan are equally strong in tenpai; kanchan is stronger before tenpai, since it is easier to upgrade into ryanmen. Tanki is the weakest, but can be suprising.

The basic patterns can be combined for more complex patterns; and the wait patterns listed here have taken on names.

==Double yakuman patterns==
==Yakuman patterns==
These two unique patterns are linked to specific [[yakuman]]. Under all possible tile waits with these patterns, yakuman is ensured; under some scoring rules, winning a hand with these patterns is awarded [[multiple yakuman#full scoring|double yakuman]]. There are no other wait patterns with more than 8 winning tiles (although it is possible for an 8-sided wait to include four of the same tile in such a way that a hypothetical fifth copy of the same tile would complete the hand).
These two unique patterns are linked to specific [[yakuman]]. A yakuman is ensured no matter which tile is scored; under some rulesets, these patterns are worth a [[multiple yakuman#full scoring|double yakuman]].
 
These patterns are the widest in the game. The widest non-yakuman wait is an 8-sided wait.

These combinations involve patterns that do not have specific names. Instead, they use combined forms of the other patterns. Furthermore, they mostly 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.
