Hello, enjoy this puzzle!
All feedback and comments will be much appreciated!
This is fairly approachable with perhaps a few sneaky spots. :)
Do have a go and let me know how you got on!
Rules:
- Normal sudoku rules apply.
- Along thermometers, digits must increase from the bulb end.
- Dark grey lines are palindromes and must read the same in both directions.
- Digits along the red line all have the same parity (odd or even).
- Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 1:2 ratio. Not all dots are given.
Lösungscode: Row 1 followed by row 9.

I really like this simmetrycal pattern, although I had to bifurcate in order to be able to choose the correct option. Could you explain how the puzzle is disambiguated? I suppose black kropki dot helps, but I was unable to use it

Hi, thanks for playing! The intended solution is as follows (spoiler): after filling in all the thermo options, the black dot forces the 5 in column 9 in box 9. This means that r8c8 and by palindrome r7c6 cannot be 5, and forces 5 into r7c4.

thanks, I supposed the dot should help me by telling the numbers that could be put, I wasn't aware that it also gave information about the numbers that had to be moved away from it. Thanks again for improving my knowledge as a solver
