Sequential Sums (Disjoint groups killer sudoku)
(Published on 28. October 2023, 17:29 by sujoyku)
- Normal sudoku rules apply.
- Disjoint groups: Cells in the same relative position must contain distinct digits in each 3x3 box. If, for example, R1C1 contains a 5 neither R4C4, R4C7, R7C4 or R7C7 may contain a 5.
- Killer cages: Digits in a cage do not repeat and sum to the clue in the top left.
- Diagonal: On the negative main diagonal digits do not repeat.
Here you can solve the puzzle online:
Solution code: Column 5 from top to bottom (9 digits in total)

A great puzzle to introduce solvers to the disjoint rule. It paired nicely with these deliberately designated cages.

Disjoint groups has become one of my favorite constraints. The layout of this puzzle with the cage totals made that quite fun. Thanks for setting and sharing!
