On your marks, Get set, Whisper
(Published on 24. April 2026, 06:00 by Sudokujoker)
This is the first sudoku puzzle I've designed, which features a twist on the well-known German Whispers rule.
Normal sudoku rules apply: place the digits 1-9 in each row, column and 3x3 box. Dynamic fog: the grid is covered in fog. Correctly entering a digit will clear the fog in that cell and may clear the fog in other cells too. German Whispers: adjacent cells on a green German Whispers line must differ by at least 5. All possible German Whispers line are drawn in this puzzle.

That was lovely! I didn’t use the negative constraint at all, but flowed nicely all the same :)

I don’t believe I’ve ever seen a negative constraint on a GW puzzle. And it was fascinating! Awesome job for your first puzzle, @Sudokujoker!
