Small Diagonals
(Published on 12. December 2025, 07:19 by PrpLTrtL)
Normal sudoku rules apply.
Digits increase along the thermometer with the lowest digit starting in the bulb.
Digits in boxes look diagonally. Calling the digit in the box N, there are exactly N amounts of the same digit in its diagonals. (For example: if we put a 2 in the box, then it will see exactly two other 2s in its diagonals.)
Good luck!
Solution code: Row 7:

Well that ending was brutal

Strangely, the hardest part of the puzzle came after I'd filled out all the diagonal-box-related squares, and was just left with a bunch of 6789s all over the place. Nothing really seemed to help (too many digits for X or Y-wings, coloring derailed immediately), so eventually I just gave up and started brute-forcing the solution, and even then, contradictions only showed up 20+ moves deep.
