Region triplets
(Published on 7. July 2025, 20:39 by Adrian71)
- Normal sudoku rules apply.
- Region triplets are three digits on a straight line which form a region sum line. A region sum line is a line that crosses at least one 3x3 box border and whose digits sum to the same total in each 3x3 box it visits.
- Region triplets are indicated by blue lines. All region triplets are given.
Solution code: The digits in column 9, top to bottom

Very nice! The negative constraint is an interesting twist on the region sum lines. No bifurcation required, but there are a couple of tricky steps (unless I missed something). That's 4 stars difficulty for me.
It's a bit sad to see many great puzzles with so few solves.

Thank you for solving and for your kind words! I am really glad you enjoyed the puzzle :)

Anything but average lol. Solvable, but I kinda want to see the intended method to finish the puzzle.
