Rules:

Normal Sudoku rules apply. Digits may not repeat along the negative diagonal.

  • Kropki Dots: Digits separated by a white dot are consecutive. Not all dots are necessarily given.
  • Region Sums: The box borders divide blue lines into segments with the same digit-sum; different lines may have different sums.
  • Palindromes: Digits along a grey line read the same forwards or backwards (i.e. 12321).
  • Sequence Thermometer: Adjacent digits along the red line always have the same difference, and increase from bulb to tip.
  • German Thermometer: Adjacent digits along the green line must differ by at least 5. Non-adjacent digits along this line increase from bulb to tip (i.e. 1829 would be valid, but 2918 would not).

Solution code: Every digit in row 9, from left to right.

A little overwhelming with the amount of overlapping and connecting lines, but the ruleset is nice. The logic had a good flow after i found where to look at. Alltogether nice puzzle, thanks.
