- White kropkis: If two orthogonal digits are separated by a white dot, they must be consecutive (negative constraint, ie. no digits may be consecutive without a white dot between them).
- Black kropkis: If two orthogonal digits are separated by a black dot, one must be double the other (negative constraint).
- Anti-knight: - A square must contain a digit different from every other square a chess knight’s move away.
Solution code: First row, left-to-right.

Love a negative constraint and that's a proper one.

I think instead of the white kropki rule, you should just have a regular anti-consecutive rule. I've done a couple of other puzzles like this and that's how they framed it, it's less confusing

The fun aside at the end is quite satisfying! Would be less easy if coloring wasn't so helpful.

The rules here are updated, but on the app it's still unclear.

Updated white kropki rule to clarify things.

Thank you for this nice puzzle, lgastako! You might want to clarify the rules in regard of 12 pairs on black dots. I think right now it is not 100% clear if those are permitted or not.

(lgastako): Thanks for pointing this out - I've updated the rules.
