Puzzle rules
Normal Sudoku rules apply.
On a green line adjacent digits must differ by at least 5 (standard German whisper)
If two digits are separated by a black dot, one must be twice the other (partial Kropki - not all dots are necessarily given)
Here is the Cracking the Cryptic link: Twice a night
Here it is on F-Puzzles: Twice a night
Solution code: Row 3

Was quite challenging puzzle but really had some interesting ideas I didn't see it before on whisper line sudokus. Superb puzzle.

Surprisingly magnificent!!! I have solved millions of puzzles based on whisper lines, of which several used black dots to disambiguate, yet this one is incredibly, unexpectedly full of fascinating logic that I have never seen before.
Be aware that this is a challenging puzzle from start to end, and I bet it will give you a hard time if you try and solve it without using some clever trick to simplify your notation!
Thanks for the comment. Glad you enjoyed it!
