- Normal sudoku rules apply
- N-Whispers: digits adjacent along a line/shape must differ in value by at least 'N' where 'N' is the number of cells the line/shape passes through; digits may repeat on lines/shapes if allowed by other rules
- Kropki: digits separated by a white dot differ by exactly 1 while digits separated by a black dot have a ratio of exactly 1:2; individual grey dots may function as a white and/or black dot and not all dots are given
Solution code: Row 1 and Row 9

The way the different lines worked together was very spectacular. Brought out a lot of logic you don't see in other puzzles.
REPLY: thanks for solving!

A fascinating variant, but very tough. Thanks.
And the grey dots worked fine on my CTC (slightly swollen, but perfectly visible).
REPLY: Very kind indeed; glad you persevered with it!

Quite challenging, every digit had to be earned. Enjoyed it a lot.
REPLY: Many thanks, fuxia! Lovely to hear from a gifted setter such as yourself

A nice Whisper variant! For some reason, the grey dots weren't visible on F-puzzles or CTC app.
REPLY: many thanks! not sure why you couldn't view it properly but glad you were able to solve it despite this!
