Atrocious Destruction
(Published on 14. November 2025, 00:00 by NXTMaster)
The rules are as follows:
- Place the digits 1-8 once in every row and column.
- Chaos Destruction: All given regions must be "destroyed" by making sure they do not contain all the digits 1-8. The grid also consists of eight hidden, orthogonally connected regions that each do contain all the digits 1-8. Digits in circles represent how many of its orthogonally and diagonally adjacent cells, including itself, belong to both the given and hidden regions where the circle resides (i.e., where they overlap).
The puzzle is available on SudokuPad with answer check on only the sudoku digits but also available on Penpa+ with answer check on sudoku digits and hidden region boundaries using the Green Edge tool (mark the perimeter/border). Have fun destroying!
Solution code: Row 5, Column 6. Include a "-" to separate digits belonging to different hidden regions and a "+" to separate the row from the column.

Nice, clean solve. I’m seeing your destructive intentions more clearly now!

Agree with below comment, I love that the restriction has been used. I forgot many things over the course of this one, but it was not terrible when I did it properly.

Quite a jump up from the previous one! It's neat to see the "all starting regions must be invalid" rule come into play, though it had me stumped for a fair bit.

Very fun, a bit challenging for me, especially at the very end where I accidentally colored two cells the same way instead of opposite, took me quite a while to realize the mistake :D
