The normal Sudoku rules apply.
Each or the 4 shaded boxes are associated with a different constraint: Thermo, Arrow, Between Line, German Whisper. Any line that passes through a shaded box must meet the constraint associated with that box.
All lines are at least one of the following: Thermos, Arrows, Between Lines, or German Whispers. If a line passes through two boxes then it must obey the constraints for both boxes.
The type of each line and the type of each shaded box must be recognized by the solver. The different line colors are purely cosmetic and have no meaning for the puzzle.
Numbers separated by a white dot have a difference of exactly one.
Summary of the line rules
German Whispers : Neighboring digits along the marked gray lines have a difference of at least five.
Between Lines : Digits in a line have a value that lies exactly between the two digits at both ends of the line.
Thermo : The digits of a thermometer necessarily increase as they move from one end to the other.
Arrow : One of the numbers at the end of the line must equal the sum of all other numbers in the line.
Solution code: Row 2, Column 2

Formatted so the link more obviously appears above the image.

Updated the rules to make them clearer.

The lines which do not pass through any box must obey at least one of the constraints. The lines which pass through two boxes must obey the constraints for both boxes.
I will edit the rules to reflect this.

I made a link for this: https://f-puzzles.com/?id=ydvrpzwa
But also had the same question as Skorp but made an assumption in the rules description I included.

etwas verwirrende Regeln
Mehrere Linien laufen durch 2 Boxen, gelten dann beide Einschränkungen?
Und 2 Linien laufen durch gar keine schattierte Box, was ist mit denen?
Ich nehme an, die Boxen definieren nur die jew. Einschränkung und unterliegen nicht derselben
