FYI, in the rules text on Sudokupad, you forgot to explain what the "X" is
(Like, of course most of us know what the "X" is, but presumably the rules are supposed to explain ALL the constraints that aren't part of the normal sudoku rules)

Fun puzzle and no anti-knight constraint in case you’re wondering.
