A Box of Thermometers

(Published on 4. March 2026, 18:26 by Leaving Leaves)

This is my first 9x9 sudoku. Hope you like it!

Normal 9x9 Sudoku rules apply.
Digits on thermometers must strictly increase from bulb to tip.
Thermometers *CAN* share cells with each other, and even *OVERLAP*.
The thinner dark gray lines are purely aesthetic.

Very creative use of thermometers indeed! Still stumped me even after knowing what I should do

From seemingly impossible to solve, everything slowly untangles. Very novel use of thermometers.
