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.)
V Pairs: Digits separated by a V sum to 5. All Vs have been given.
Consecutive Pairs: Digits separated by a white dot must be consecutive.

Struggled about halfway through until I realized I’d missed the negative constraint on Vs and was able to proceed quickly to a solve from there! Really enjoyed the negative whisper constraint!

Brilliant puzzle! Very unique, which is hard to pull off with such rule set. I had a lot of fun.

This puzzle was SO MUCH fun. It took me a while to figure out some of the deeper implications of the negative constraints, but I thoroughly enjoyed the solve.
