2023 Chaotic X-Sums
(Published on 19. February 2023, 15:24 by Florian Wortmann)
This is the last puzzle in my "23" series and I think it's a worthy conclusion. Happy solving :-)
Normal Sudoku rules.
Chaos Construction
Divide the grid into regions, each consisting of eight orthogonally connected cells. Each row, column and region must contain the digits 1-8 once each.
X-Sums
A clue outside the grid is the sum of the first X cells in the corresponding row/column, where X is the digit in the cell nearest to the clue.
In addition, in every row/column with a clue, the first X cells are in the same region, and the X+1th cell is in a different region.
A ?-clue also has this region building property but the sum is unknown.
Even
A cell with a gray square contains an even digit.

Came here after solving the 2024 puzzle. I may be a year late, but I had fun anyway. Thanks! :)

This was a great puzzle! I loved the interactions of the region construction and the X-sums.

Nice one, but the ending took me way too long. The last 3 regions were really hard to solve. At least for me ;)

Thanks! Yeah, the logic in the end is a bit different from the first half, so no worries for spending a bit longer there ;-)

That was a pure joy; just the right difficulty for my level. It is very even throughout which I think is really nice.

I don't know what I did wrong, but right at the end of the puzzle, I was left with a deadly pattern! Luckily, it was only for the last 6 cells, but I'd love to know the solution path, as I've been over my solution 5 times but still can't figure out what I did wrong! That said, an amazing puzzle, had a great time solving it!

Thanks for the solve! Can you provide a link to your grid in a hidden comment? You can also contact me on discord (Florian Wortmann#6520). I'll be happy to help :-)

Edit:- Thanks for looking into and helping me out! In the end, it was an oversight on my end, and the puzzle was perfect!

You're welcome! :-)
