Hidden Thermo Sudoku
(Published on 28. September 2021, 17:06 by Prutsbeest)
Normal Thermo Sudoku rules apply (digits along a thermometer must strictly increase).
The thermometers in this Sudoku are all hidden, only the bulb and tip of each thermometer is given, with the exception of the brown and grey thermometers, where only the tip is given. Corresponding tips and bulbs share the same color. All thermometers must be at least two cells long.
Furthermore, thermometer lines cannot cross and thermometers cannot touch each other (i.e. thermometers cannot share a cell).
This puzzle can also be solved on f-puzzles: https://f-puzzles.com/?id=ydkv2wzu
Good luck!
For a hint regarding the break-in, select the white text below:
Have a look at the red, green and (dark) blue thermometers. How can they be connected together without crossing lines?
Solution code: Row 3 followed by column 3 (18 digits, no spaces)

Thank you all for your kind words! :)
After reading the comments on the CTC video, I changed the wording in the ruleset to hopefully make it a bit more clear.

I absolutely loved this puzzle, some tricky logic, can easily be led astray, a beautiful puzzle.

Stunning puzzle! Even though I found the break-in immediately, I struggled a bit at the corner boxes. Messed up my pencil marks a couple of times, and took some naive deductions at places, but I got through to it in the end!! So satisfying to watch it all come together at the end. Amazing job! :D

Fantastic puzzle!

There must be something that I'm not interpreting correctly with this ruleset, because it definitely is not solvable as I understand it.
Edit: Nevermind, I very seriously lack visual imagination skills!

Wow! Amazing puzzle. I was also convinced it was impossible, but then I broke through. Super satisfying with wonderful twists and turns throughout. Straight to my favorites!

This is an absolutely wonderful puzzle. Those who think that this puzzle is impossible like me, please have a look at it again more carefully. You will be amazed when you figure out the break-in.

Updated ruleset

Thermometers must be at least two cells long. Is that right?
----------------
Hi kolot,
Yes, that is correct, thermometers must be at least two cells long, I will add this to the rules as well, thank you!

It seemed impossible to me but I finally got it. The break-in was absolutely crazy.

Updated ruleset to make it a bit more clear.

I agree with filuta about unclearity of the rules. Unfortunately, I still don’t understand the rules even after filuta’s clarification. I think I am missing something about the rules. For example, is it possible that R1C1 and R2C2 belong to one thermometer, and R1C2 and R2C1 belong to another? They won’t share a cell but will cross each other.

Hi kolot,
I'm sorry for the confusion. You are absolutely right: thermometer lines cannot cross each other, so if a thermometer goes from R1C1 to R2C2, there cannot be a thermometer going from R2C1 to R1C2.
I adapted the ruleset slightly to make it more clear, any suggestions to make it even more clear are welcome!

Thank you for the reply! The puzzle seems impossible to me with these rules. I should be missing something. I will think about it again.

cool idea and really original break-in, I had so much fun with this one.
the rules are a little bit unclear though, when you write that thermos cannot cross, you mean they cannot even touch (i.e. they cannot share a cell), I think this ambiguity might make it harder to spot the break-in.

Hi filuta,
Thank you for the feedback! Indeed, thermometers cannot share a cell either. I tried adapting the rules to make it more clear. Any suggestions to make it even clearer, are welcome of course.

Added hint for the break-in

ist das Absicht, dass dort 2 Farben vorhanden sind, die jeweils nur 1 mal vorkommen? (grau / dunkelbraun?)
-----------
Hallo SKORP17, ja das ist beabsichtigt, das sind nur die Endpunkte des Thermometers.
