Rules:
Normal Sudoku rules apply.
German whispers: adjacent digits along a line must differ by at least 5.
Additionally, nine cells in the grid are "doublers", which count as double their value for the purpose of the whipser lines. There is exactly one doubler in each row, column, and box, and they form a set of the digits 1-9.
Lösungscode: Row 9 followed by column 8 (18 digits no spaces)

I'm surprised I've only recently learned about this one, as I'd been pursuing a roughly similar goal since probably longer than it's been posted :O
I'm amazed at how ultimately minimal the grid is; I think I like it even more than the still equally impressive Not One Black Dot by mormagli, if only because of the involvement of the doublers. Bravo!

Spent about three hours, after my dad already tried it yesterday and failed and called me for help. We spent quite a while whittling down the options of the line in column three, and eventually came to the right conclusion after knockon effects through half the grid

This puzzle does a great job of displaying cool interactions between the two rules. Excellent work.

5 does not belong on a german whisper line. There I said it (lol). Very good puzzle, and the doublers really makes you call into question everything you know about german whisper lines.

Exceptional puzzle, had a lot of fun with this and it was on the more approachable side of 4 stars imo. Awesome job, thanks!
