• Normal Sudoku rules apply.
• Adjacent digits along a green German whisper line must have a difference of at least 5.
• Digits along a dark orange Dutch line must have a difference of at least 4.
• Digits along a light orange parity line must alternate between odd and even.
• Digits along a blue line create a sumline where the sum of digits on a line within a particular 3x3 box must be the same for all the boxes the line passes through.
• Digits along each grey thermometer must increase starting from the bulb end.
• Cells with a filled circle must be odd.
• A black dot between cells indicates cell values with a 2:1 ratio.
• A white dot between cells indicates cells with consecutive values.
• Not all dots are shown.
• A V between two cells means they add up to 5.
• An X between two cells means they add up to 10.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
Lösungscode: Enter digits in 6th row.

You don't have to assume that the lines are symmetrical or the sum lines don't branch. You get to a point where you know the sum is either 12 or 13. The only way 12 works, even with branching is 1+2+3+6 in the middle box. But that forces a few more cells and you quickly get a contradiction.

i had to guess that the lines are symmetrical (i don't know if i can do that or not) for me to solve it, but once i found a single digit around the 7-8-9 column, it flowed very nicely

Thank you for the puzzle. The interactions between the rules are very clever and the butterfly image is a delight.

Lovely puzzle, thank you. I struggled a bit deciphering the difference between the orange lines but that's probably just my poor eyesight!
