Heard No More 7
(Published on 6. February 2025, 19:57 by The Bard)
Normal Sudoku rules apply, place the digits 1-9 in each row, column, and box.
German whispers: Adjacent digits on a green line must have a difference of at least 5. All German whisper lines have been given that would be vertical or horizontal. (i.e. There is a negative constraint, but this does not apply to diagonally adjacent digits.)
X Pairs: Digits separated by an X sum to 10.
Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.
This is a sequel to Heard No More,
and Heard No More 6.

I think I've never had German whispers as a negative constraint. Very neat!

Hard enough to make me think, easy enough to use it as a pleasant work break. Despite its ease, I found the fact that it solves due to the negative constraint to be quite clever.
