Normal Sudoku rules apply. Digits in cells joined by a black dot are in a 1:2 ratio.
German Whispers: Adjacent digits along a light-green line have a difference of at least 5.
Monogamous Whispers: Adjacent digits along a dark-green line have a difference of at least 5, and the line must contain both of the digits 4 and 6.
Solution code: Column 9.
