Rules are as follows:
• Normal Sudoku rules apply. (Place the digits 1-9 once each in every row, column, and 3x3 box.)
• Normal German Whispers rules apply. (Adjacent digits along green lines must differ by at least 5. Example: 1-7-2-9-3.)
• For each of the digits 6, 7, 8, and 9, there must be at least one of the same digit a knight's move away.

I ended up having to restart this one because of a dumb mistake (twice!) on my part when marking possible digits in r1c1 but really enjoyed the logic :).
