Odd Mutant

(Published on 4. March 2023, 05:00 by Will Power)

Normal Sudoku rules apply. Numbers in gray circles are odd. Numbers in cages sum to the number in the top left corner of the cage. Numbers cannot repeat in cages. Numbers in GREEN cells are the SUM of two of the orthogonally adjacent odd numbers. Numbers in RED cells are the DIFFERENCE of two of the orthogonally adjacent odd numbers. The number in the BLUE cell has BOTH green and red properties. All possible green, red and blue cells are shown.

I also got a deadly pattern and didn't notice the negative constraint until I read the comments.
and yes, the negative constraint solves the deadly pattern.

This is my favorite ending of.a Will Power Puzzle. Great use of the negative constraint to resolve it.

@VeTaurus I ran into the same problem, but with @Snaques's hint, it was possible to pick the "right" pairing. Consider: r1c3 is white, not red. One possible resolution would have made it eligible to be red, so that's the wrong one.

@Snaques: Thanks for the hint. But I still don´t get it. Since it is not necessary for the solution code, it makes no difference ;-)

@VeTaurus, I think the two pairs in the end are solved through the negative constraint "All possible green, red and blue cells are shown."

The puzzle was nize, but a bit hectic for my taste.

Somehow I end up with two possible solutions. I have two pairs in r1c4 / r1c5 and r6c4 / r6c5 that can be solved both ways. F-Puzzles shows both solutions as correct and the "difference rule" for r7c5 is also fulfilled.

Great puzzle! Thank you for sharing! The forum badly needs more 1 star puzzles.

I don't normally do coloured puzzles because I prefer to colour myself. This was ok though and still very easy.
I think I'd have preferred to have "+", "-" "+/-" in the corners of the cells instead of colours.
Still a quick, fun Sunday morning puzzle.
