Normal sudoku rules apply
Every 3x3 box has the same number in every one of it's own kropki dots. Each 3x3 box has a different number (in its kropki dots) then all of the other 3x3 boxes. You must figure out which of the numbers 1-9 correlates with each box's kropki dots. (The number in each dot is the difference between the digits that go in the cells seperated by the white kropki dot)
For example: box 1's kropki dots would all be the same number and no other 3x3 box could share that number in it's kropki dots.
Within each 3x3 box there is a negative constraint for the white kropki dots. (THIS DOES NOT APPLY TO ANY OF THE BORDERS ALONG THE 3x3 BOXES)
Solution code: Last row of digits

Went quite quickly once I got my head wrapped around the rules. Still, this was fun! I don't think I've seen this constraint before.

Wording of the rules is still a bit difficult to understand. There is a puzzle by Richard which I think is the same rules
