Different Sums
(Eingestellt am 3. Februar 2026, 21:16 Uhr von mimec)
I made a few attempts to set this puzzle and I wasn't even sure if it was possible using this ruleset alone, but in the end I found a way to do that. It's basically a region sum line sudoku with two additional rules (see below).
Rules:
- Normal sudoku rules apply.
- Box borders divide the blue region sum lines into segments. Digits within each segment must sum to the same total. This total must be different for each line. Digits cannot repeat along a line.
Lösungscode: Row 6

Very nice but tough. Took me 61 minutes and I had to use uniqueness twice. Obviously not the intended path.

this qualifies as level 2 : easy for experts, but still doable by non-experts, with effort.
to see this, do not get distracted by trying to solve the lines at first, but concentrate on BASIC SUDOKU.

Very nice! Reading the rules carefully, which I did not at first, helps a lot. Thanks
