Sudoku Variants Series (419) - Dutch Whisper Lines
(Published on 11. April 2025, 12:00 by Richard)
Logic solvable
Dutch Whisper Lines
Inspiration for this type comes from Scruffamudda.
Solve online in Penpa+ or in Sudokupad.
Like all of my sudoku variants, this puzzle can be solved by logic alone. Guessing is not required and also no sophisticated solving techniques are necessary; just plain and easy sudoku steps and of course the intrinsic logic this specific variant has to offer. In case you don't find that logic or get stuck, feel free to ask for a hint in the comments below this puzzle and I'll be happy to help you.
Apply classic sudoku rules.
Adjacent digits along the marked orange lines have a difference of at least four. Digits may be repeated on lines.
Solution code: Row 4.

Delightful! And I think you’re right: this is the first pure DWL-puzzle. Thank you very much for creating and sharing it.

Nice to see a 'pure' Dutch whispers puzzle. It's such an elusive constraint.

I wouldn't be surprised if this is the only 'pure' DWL puzzle in the entire portal. When I created this puzzle a few months ago, I searched for a pure one, but couldn't find, although according to my wife my search capacities are limited (at least for finding 'lost things' in the house). So maybe there are one or a few, but it can't be many. :-)

By 'elusive' I also meant 'difficult to make interesting'. However, you certainly succeeded! Nice work.

Lovely puzzle! I did go a bit too quickly and had to rewind due to a false deduction. But once I took more care, it all flowed beautifully again. Thank you, Richard!
