Clueless Knight XV
(Published on 8. February 2023, 00:58 by Lutterot)
Standard Sudoku rules apply.
Cells separated by a knight's move (in chess) cannot contain the same digits.
Digits separated by an X sum to ten; digits separated by a V sum to five; digits separated by a white dot are consecutive. Every possible X, V and white dot is given. The puzzle does not contain any white dots.

For a more challenging solve, ignore the anti-knight constraint.
Solution code: Diagonal from top left to bottom right

By the way, the "harder version" that ignores the anti-knight constraint, still has the Anti-knight constraint still baked into it in Sudokupad.
Like, if you have the conflicts-checker turned on, it highlights squares that are a knight's move away as conflicts, even in the version that's supposed to have the anti-knight rule turned off
Lutterot: Thank you for the feedback. I fixed it.

Fun puzzle. Appreciated reminder in the comments to take note of negative constraints.

Nice and easy puzzle! Fun idea with the nonconsecutive + V's.

Took me a while to "grok" the rules and really focus on the negative constraint around white dots and their non presence.

Remark about anti-knight added.

@cegie: You are absolutely right. I only included the anti-knight constraint in order to be able to classify the puzzle as "very easy", but the solution is unique even without that constraint.
