Sudoku Cue correctly identifies a swordfish (Sashimi, not really finned)
and will remove candidate 4 from r8c6 but misses removing the 4 from r2c4.

This is the original puzzle.

Code: Select all

. . . | 1 . . | . . 8
. . 7 | . 3 9 | 1 . .
. 3 . | 5 . . | . 7 .
---------------------
3 . 6 | . 5 . | . 1 .
. 8 . | 2 . 1 | . 3 .
. 5 . | . 4 . | 8 . 7
---------------------
. 6 . | . . 2 | . 8 .
. . 2 | 8 1 . | 5 . .
4 . . | . . 5 | . . .

Ruud, did you look at this?

Zoltag,

When you place [[Color_Wrap|Color Wrap]] before the finned fish in the solver settings, SudoCue will perform 6 eliminations for digit 4 in a single move.

Finned fish only perform eliminations in a single box, although subsequent singles will do the remaining eliminations.

Thanks, I don't use colours.

I drew attention to the fact that this is a sashimi because it acts like a skyscraper and does eliminate in more than one box.
How do you justify claiming that the cell r7c4 is the "fin" rather than r3c6?

Both are valid fish. r357c367 is simply found before r357c347. This may change in the future, as I'm planning to optimize the code for this solving technique.

I'm seeing that fins only eliminate in their own box.
A pattern can have fins and eliminate in many boxes.
