Love the puzzle and the clever use of Rule#3!
Thank you ♥

@VitP
A "Negative Constraint" means that all marked clues are given, such as Black Dots. It doesn't apply to the Anti-Knight rule since it's not a marked clue.

A "Negative Constraint" rule here would be along the lines of "All black dots are given." Most puzzles with no negative constraint say "Not all black dots are necessarily given."

This puzzle's wording is similar to the latter, but with an important key difference..

several people have mentioned a "negative constraint" in these comments. what "negative constraint"? "anti-knight" is NOT a "negative constraint"

FYI - the solution code that Sudokupad thinks is correct, as far as I can tell, is the incorrect solution that you would get without very careful reading of Bullet 3.

The solution code that works here as the valid solution is showing up as invalid in Sudokupad

Nice use of the negative constraint. Unfortunately for me, I am self diagnosed "boolean-challenged", so at the end, I got the wrong solution .. until I re-read the instructions 3 more times ;-)

This may be my favorite puzzle I've ever solved. I've never seen a negative constraint need to be implemented in order to give the unique solution so hats off to you, Well Done!

That is a mean positive use of negative constraint.

What an evil ending haha
I think a lot of people here will miss that extra detail on the rule set x)
