Parity Fun 44
(Published on 29. August 2026, 10:00 by galium_odoratum)
I am usually not the biggest fan of 0-9 Sudokus, but I have tried to create an approachable parity twisted variant. Have fun!
Altered Sudoku: Each row, column, and box contains exactly eight digits chosen from 1–9, with no repeats (i.e., one digit from 1–9 is missing in each).
Hidden Odd Zeros: Each row, column, and box contains exactly one hidden zero behind the fog. Zeros are never entered into the grid and must remain hidden at all times during the solve. A zero cell cannot be orthogonally adjacent to an even digit.
German Whisper: Adjacent digits on a green line must differ by at least 5.
Thermometer: Digits on a grey thermometer must strictly increase from the bulb to the tip.
Killer Cage: Digits in a cage must not repeat and must sum to the total shown in the top-left corner
Renban: Digits on a purple line must form a set of consecutive digits in any order.
Fog: Some clues are hidden by the fog.
Small note: If you find the first digit too quickly, it is likely that you have missed some logic. It is quite easy to make the right decision based on an unproven assumption for this particular break-in.

Very nice and hard puzzle, thanks!

Really enjoyed this for the better part of an hour. I forgot several times the rule about not having a zero next to an even digit, but when I was managing to hold everything in my brain at the same time it flowed very nicely.

Great puzzle! Thank you for the heads up about the first digit, I fell for immediately!
