Overview
A Finned X-Wing is an X-Wing with extra candidates (the "fin") in one of the base rows/columns. The fin restricts eliminations to cells that see both the fin and the normal elimination zone.
How It Works
- Find an X-Wing pattern where one row has extra occurrences of the candidate.
- These extra cells are the "fin".
- Eliminations occur only in cells that see both the X-Wing column and the fin.
Example
Base columns 1 and 6 form a X-Wing for digit 4 in cover rows 1 and 6.

Tips & Patterns
- The fin must be in the same block as one of the proper X-Wing cells.
- Finned fish reduce the elimination zone but still allow some progress.
- These appear when you almost have a perfect fish pattern.
