Double Dutch Dare You
I stumbled onto this puzzle while messing around with antikropki constraints.
Rules:
Sudoku: Place the digits 1-9 once each into every row, column, and box.
Dutch Whispers: 2 digits connected by an orange line must differ by at least 4.
Antikropki: If 2 digits are orthogonally connected, one cannot be double the other.
Solution code: Enter the digits from Row 8 and Row 9 without spaces.
