Rules:
Normal Sudoku rules apply.
There are 9 nullifier cells, one in each row, column, and box, each containing a different digit. A nullifier cell has a value of 0. All other cells have the value of their digit. Nullifier cells always have another cell with the same digit either a knight's move or a king's move away.
Orthogonally adjacent cells always have values of different parity.
German whispers: Adjacent values along German whisper lines differ by at least five.
Black Kropki dots: Values in cells joined by black Kropki dots are in a 1:2 ratio. Not all dots are given.
Solution code: Row 9, left to right.
