Donut
(Published on 31. July 2025, 15:10 by mimec)
This puzzle is obviously inspired by 1080° by Raumplaner and Qodec. I was curious if it was possible to create a classic killer sudoku with cages arranged in a donut-like shape, and it turns out that it is!
Rules:
- Normal sudoku rules apply.
- Digits within a cage must add up to the total in the corner. Digits cannot repeat within a cage.
Solution code: Row 5

Really beautiful one. I think it's more 3/5

Nice killer, 3/5 for me. Some restrictions in the middle game are hard to spot

Nice flow in this one, thanks! I found this harder than casual 2/5 diff though.

Trusting the logic and not running into a dead end, makes for a very enjoyable solve.
