Anti-Disjoint Killer
(Published on 11. July 2021, 17:13 by DVFrank)
Normal Little Killer and Killer Sudoku rules apply.
In addition digits in the same position relative to their boxes are anti-disjoint, i.e. must be selected from exactly three different digits.
Here is an example to illustrate the last part of the rules:
In this grid the bottom right corners of the boxes satisfy the anti-disjointness constraint, while the top left corners do not (even though they are not disjoint, they are not maximally so).
Enjoy!
Solution code: Row 5 (left to right)

I felt a bit stupid in the beginning but after trying again the next day I finally understood it. Very pleasant to solve!
[Yeah, this one might be a bit tricky if you're not too familiar with the constraint. Good on you for keeping at it though! :)]
