A few commenters indicated they did not use the anti-knight constraint, but i certainly did. This was a rather enjoyable solve! thank you for sharing.

I unused completely that anti knight rule and solved in 26 min

Fun puzzle, it's possible to solve without using odd knights OR gray circles.

Great puzzle - but didn't use/need the off-knight rule

Aside from the fact that Sudokupad confused me because it can't implement the knight rule exactly, I really liked the puzzle. It was fun, thanks for sharing.

Clarified the knights move rule and updated the Sudokupad link to include the solution.

Is the odd-anti-knight rule even needed? I don't think I've used it at all.

Very nice, despite the pad error

@Mozart40 The solution code was marked as correct despite the Sudokupad error - I imagine that the puzzle has simply had an antiknight constraint programmed.

Just to clarify: Even numbers can be one knight's move apart? This is in sodokupad shown as an error.
