Rules:

Normal sudoku rules apply, and all clues are standard.

German whispers: along green lines, digits differ from their neighbors by at least 5.

Quadruple circles: a digit inside a white circle must appear in one of the four cells surrounding that circle.

Digits in cells separated by a black dot have a 1:2 ratio.
