Franken Fish

A Franken Fish is a fish pattern where one or more lines in the defining set or the secondary set has been replaced by an equal number of boxes.

These are the possible configurations:

• N rows vs. N columns + boxes
• N rows + boxes vs. N columns
• N columns vs. N rows + boxes
• N columns + boxes vs. N rows

The irregular patterns make it possible to find larger Franken Fish than for fish types limited to rows and columns.

Although a "Franken" X-Wing is technically possible, but this degenerates into some other elementary single-digit technique, such as Claiming. Therefore, only Franken Fish of size N at least 3 is discussed.

Originally, the box constraints in a Franken Fish were seen as possible fins, but it turned out that the boxes themselves belonged to the pattern.

All other fish with mixed constraint types are Mutant Fish.
