'''Finned Fish''' is a variety of [[fish]] that has extra [[candidate]]s in a single [[box]]. Like regular fish, it is a [[single-digit]] [[solving technique]].

The same names are used for the different sizes:

; [[Finned X-Wing]]
: Size 2

; [[Finned Swordfish]]
: Size 3

; [[Finned Jellyfish]]
: Size 4

== How it works ==
Here is an example of a Finned X-Wing:
{{grid|10=/|11=X|12=/|13=/|14=X|15=/|16=/|17=/|18=/|29=*|37=F|38=X|40=/|41=X|42=/|43=/|44=/|45=/|47=*}}
The four cells marked '''X''' would be an [[X-Wing]] if the candidate in the cell marked '''F''' were not present. So either there is an X-Wing, or the candidate in '''F''' is true. In both cases, the starred cells cannot contain a candidate for this digit. We can eliminate those candidates.

The eliminated candidates can only be within the box containing the fin.

The '''F''' cell is known as the [[fin]]. In this example, there could also be a candidate in '''r5c3'''. This would be called a '''big fin''', but the effects are the same.
