Parity Fun 24
(Published on 11. April 2026, 10:00 by galium_odoratum)
Again an easier entry to the series. This time with using only classic rulesets, but with a small parity twist. Have fun!
Normal Sudoku rules apply.
Parity Rule (applies to all clues): Any digit on a clue must be directly connected (one step orthogonally or diagonally) by that clue to at least one digit of the same parity (odd or even). If a digit is part of multiple clues of different types, this rule applies separately to each clue type.
Black Kropki: Digits connected by a black dot must have a 1:2 ratio.
German whisper: Adjacent digits on a green line must differ by at least 5.
Thermometers: Digits on a grey thermometer must strictly increase from the bulb toward the tip(s). Thermometers may branch but may not cross or overlap, and each thermometer has exactly one bulb.
Fog: Some clues are hidden by fog.

Very nice puzzle! I did see that r4c5 is violating the parity rule
-Thank you for pointing this out, it is now fixed. I switched between puzzle versions too often during construction :) ~galium
