Sudoku Variants Series (435) - Slow Thermos

(Published on 1. August 2025, 04:29 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.

Slow Thermos
Apply classic sudoku rules.
Digits along a slow thermometer must either stay the same or increase from the bulb to the tip.

Inspiration for this type comes from Aspartagcus.

Solve online in Sudokupad.

Solution code: Column 9

Very pretty! A couple of times, I got so caught up in the "slow" part that I stalled while missing some progress I could've made in the regular thermo parts!

As always, a perfect introduction of an unusual constraint. Thank you very much for creating and sharing.

the rules seem to apply to diagonal sandwich sums ?

Thx!
I changed that already, but forgot to enter a change comment, so the change wasn't actually done.

That's also why this has such a strange publishing time; changed that too, but that change wasn't also actually done. :(
