Chaos Construction: X-Sums

(Published on 10. April 2022, 01:36 by KNT)

Place the numbers from 1 to 8 exactly once in every row, column, and region. Each region is orthogonally connected and must be located by the solver.

A number outside the grid indicates the sum of the first N numbers from the direction of the clue, where N is the number closest to the clue. The first N numbers are also all in the same region, and the N+1th number is in a different region. A question mark may be any positive integer.

Neat puzzle, thanks. I liked how much region geometry pushed the solve forward. 8x8 is a fun grid size.

Thanks, definitely not a pushover but also definitely more approachable than many of the genre.

Very nice indeed, and more approchable than your previous chaos puzzles as you mentioned. The contruction looks rather esthetic too when it's finished !

Fun and approachable, thanks :)

Thank you! Do you think I should lower the difficulty to 3 stars? I was a bit hesitant as I think this is somewhere between 3 and 4.

I rated it 2* difficulty actually, definitely at most 3*.
