Kill Or Quads
(Published on 12. July 2024, 08:26 by MSDOS)
This puzzle was heavily inspired by Vitaminz's "I Heard You Like Cages". I really liked the idea of an abiguous clue-type that still lead to a unique solution. I hope you enjoy!
Rules:
- Normal sudoku rules apply.
- Each marked circle is either a Killer Quad OR a normal Quadruple, with each to be determined by the solver.
- Killer Quad: Digits surrounding a circle must sum to the indicated total.
- Quadruple: Digits marked in a circle must appear in its surrounding cells.
- Note: Each 2x2 area surrounding a circle satisfies only one of the clue types.
Solution code: Column 8 from top to bottom (9 digits).

Very cool puzzle! It's nice that so many deductions can be made in the face of so much ambiguity.

Very nice. Thanks. As always, I forgot the negative constraint and wasted much time :)

MSDOS: Thanks for the comment! Interestingly, you don't need to use the negative constraint, but then it pushes the difficulty and solve-time up quite a bit.
