Sudoku Variants Series (470) - Harmonious Thermos

(Published on 5. June 2026, 06:00 by Richard)

For this Sudoku Variants Project I have planned to publish a unique Sudoku variant every week.
I will see how long it takes before I am running out of ideas.

Harmonious Thermos
Apply classic sudoku rules.
Digits along a thermometer must strictly increase from the bulb end. Additionally, the sum of the digits along a thermometer must be divisible by the number of cells the thermometer passes.

Inspiration for this type comes from sujoyku.

Solve online in Sudokupad.

Solution code: Column 9

Pretty straightforward, albeit with an external Killer Calculator. I particularly enjoyed boxes 1 and 5 as introductions to how I'd have to think about this clue type.

Nice pizzle. I know many solvers are great here and do not need solution checking.. but for newbies like me, it would be good to have it.

Maybe I missed something obvious but boxes 1-2 felt like a huge difficulty spike
