X knighting
(Published on 20. July 2023, 18:42 by palpot)
I think this puzzle is a round 2.5-3 stars difficulty. I've added a hint below the image in case you get stuck. Happy solving!
Rules:
Normal sudoku rules apply.
AntiKnight: Cells separated by a knight's move (in chess) cannot contain the same digit.
XV: Cells separated by X must sum to 10. all Xs are given (negative constraint).
The light blue lines are both German whispers and region sum lines.
German Whisper: Adjacent digits along a green German Whispers line must have a difference of at least 5.
Region sum line: The sum of digits on the line is the same within each box. Different lines may have different totals.
Hint: Consider where the X pair digits in R3C12 goes in boxes 4 and 7.
Solution code: Column 4 digits from top to bottom.

It took quite a while to figure out the coloring, and even then I thought I broke it a couple of times.
This was a fun puzzle. Thank you for setting it.
