Temperature Inversion
(Eingestellt am 10. Februar 2023, 09:04 Uhr von Die Hard)
Normal Sudoku rules apply. Digits on the marked diagonal must not repeat. Digits separated by a kings move must not repeat.
The grid contains a number of "bi-directional thermometers" (ie: digits must increase from the bulb end, but the bulb end is not known). Each thermometer contains either all odd or all even digits. The blue and red thermometers are special as follows:
- The position of their bulbs are known and are coloured.
- The blue bulb is colder than the red bulb (ie: it contains a lower digit).
- The blue thermometer is colder than the red thermometer (ie: the sum of all of its digits is lower).
A number of people have asked to play the harder version. This is not recommended, but is available here:
Lösungscode: All 9 digits from row 5 (the middle row).

I hope the community pardons me for commenting on a puzzle I haven't solved. I wholeheartedly concur with the setter that not every puzzle has to be hard. After all, children, newbies and people like me, who are weak at solving, and come to this site looking for approachable puzzles. Thanks for looking out for us.

This puzzle design deliberately prioritised enjoyment over difficulty. There are two "thermometers" in the puzzle that are completely unnecessary for the solve. In my mind, not every puzzle needs to be a 4 or 5 star difficulty. Let me know if I made the right call.
