Antiknight: Any two cells separated by a knight's move in chess cannot contain the same digit.
Ratio Kropki Dots: Digits separated by a black dot have a 2:1 ratio. ALL black dots are given.
Consecutive Kropki Dots: Digits separated by a white dot are consecutive. NOT all white dots are necessarily given.
Solution code: Row 1

This was super fun. I got surprisingly far into the breakin before I got stuck because I had forgotten the antiknight constraint

break in to me felt borderline 4* .. as superkinkel said the black kropkis do near nothing at first.
Ah well, got the triplets in (almost) and gained some traction .
Very Nice set up, truely non obvious break in [to me that is]

Great puzzle, surprising how little the black Kropkis are helping in the beginning.

Really fun! Loved how everything interacted together. The break-in took a me a bit but once I figured it out, it flowed very nicely!
