A '''loop''' is a cyclic pattern of [[link]]ed [[cell]]s or [[candidate]]s.

Loops are usually represented by [[chain]]s, where the first and the last cell are the same. Like a chain, [[implication]]s in a loop can either travel in a single direction or in both directions. A bidirectional loop is better known as a [[Nice Loop]].

Examples of loops are:
* [[Turbot Fish]]
* [[Fishy Cycle]]
* [[XY-Ring]]
* [[XY-Cycle]]
* [[Nice Loop]]

Notation systems are similar to chain notation, with '''Nice Loop''' notation especially designed for loops.
