German Whispers Sandwich Sudoku

(Published on 4. July 2020, 11:47 by Jesper)

This puzzle is based on the German Whispers-constraint invented by Realshaggy. After becoming aware of this variant through the excellent SVS 271 by Richard, I had the feeling that this type of constraint would have an interesting impact on sandwich sums, so I decided to create a combination. Enjoy solving!

Rules
- Normal Sudoku rules apply
- Adjacent digits along the marked grey lines have a difference of at least five
- Clues outside the grid indicate the sum of all digits placed between the 1 and the 9 in the respective row or column

Very nice, I loved the row 5 deductions in the beginning. Indeed not 4 stars anymore because of all the experience with these constraints. Thank you.

Felt more like a 3* by today's standards, but still an awesome construction ! Thanks :)

Brilliant! Really enjoyed this rule combination. Thanks Jesper! :)

EDIT @Vebby: Thank you for the kind words! I must say I am very impressed with the speed with which you are working your way through my back catalogue at the moment :)

@henripijames: the official puzzles and sudokus from World Championships are copyrighted by the World Puzzle Federation. Member-organisations like LMGermany can give limited access to their individual members. So if you are a member of LMGermany you can find the puzzles in the menu under Championships / World Sudoku Championship.
The instruction booklet should be available for anyone interested.

Anyone know where I can find the original German Whisper sudoku from the world championship? The official WC website doesn't have the puzzles (or the solutions), strangely.
