This Is Knots!
(Published on 12. July 2021, 01:00 by Lisztes)
Normal Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.
Killer Sudoku rules apply. The sum of all numbers in a cage (marked with dashed lines) must match the small number printed in its corner. No number appears more than once in a cage.
The white dots represent a difference of 1 between two neighbouring cells. NOT all possible white dots are indicated; a.k.a. no negative constraint.
The puzzle is also available online.
Solution code: Row 2 and Column 2

Fun! loved the elegant yet simple knot logic :)

I didn't quite get the intended logic and had to brute force through the central cells for the kropki dots. I did realize that there was some sort of parity trick with them, but then I'm not very clever.
I did enjoy the puzzle, though!

Really fascinating how the knots interact with its neighbors. Beautiful solve and nice logical steps.
