Normal Sudoku rules apply.
Zipper Lines : On purple zipper lines, digits that are at an equal distance away from the center must have the same sum. If the line is of odd length, the sum is the digit on the center.
Anti-Quads : Digits in a white circle must NOT appear in the four cells touching that circle.
Solution code: Row 2

Tricky! But ultimately satisfying

I must admit, I solved it by trying all the options, but then I saw the logic behind the break-in, and it was stunning.

Possibly the most staring blankly wondering how on earth I'm going to get *anywhere* with this that I've ever done at a puzzle I ultimately solved without hints or cheating.
(If it's not clear, this is a very positive review.)
