Rules
This puzzle uses the standard german whispers and killer cage rules.
- Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- The digits in a cage must sum to the number printed in its corner. Digits may not repeat within a cage.
- Adjacent digits along each german whisper line must have a difference of at least 5.
Hint (select to show)
Prove that the white cells touching box 5 (R3C5, R5C3, R5C7, R7C5) need to contain four different digits.
Solution code: Row 1 without spaces

Needs a diagonal sum or something to disambiguate at the end.
