This is my third puzzle in a trilogy about mysterious lines. I constructed this puzzle on September 8, 2021. The first one in the series is Mysterious Lines and the second is Mysterious Lines 2: All WRAPT Up.
Normal sudoku rules apply.
Adjacent digits on a line have a difference of at least 5. No line contains the exact same set of digits as any other line.
A line is also either a thermometer or an arrow:
Thermometer: One end of a line is a bulb, and all digits along the line increase from it.
Arrow: One end of a line is a circle, and all other digits along the line sum to it.
(Note: The green line in box 1 is green just to distinguish it from the overlapping gray line.)
Lösungscode: Enter rows 4 and 7
