A '''Mutant Swordfish''' is a [[Mutant Fish]] of size 3.

Here is an example:

[[Image:mutant swordfish.png]]

All the [[candidate]]s in [[row]]s 1 and 9 and [[column]] 7 (the [[defining set]]) are located in column 2 and [[box]]es 3 and 9 (the [[secondary set]]). To complete these 3 defining [[constraint]]s, every secondary constraint will contain an instance of the selected digit, allowing us to eliminate all candidates that do not belong to the defining set.

The following example shows that the defining set can also include a box:

In this example, the defining set is row 8, column 8 and box 1. The secondary set is row 2, column 2 and box 9.
