Extended Sudoku rules apply: Place the digits 0-9 in each row, column, and box, however there will be one digit in each that does not fit. This digit can vary between rows, columns, and boxes and needs to be determined by the solver.
XV: Digits separated by an X sum to 10, those separated by a V sum to 5. All Xs and Vs have been given.
German whisper: The difference between two adjacent digits on the green line is at least 5.
Renban: Digits placed on purple lines must be a non-repeating set of consecutive digits in any order.

That additional 0 is really messing with my usual approach, which is actually really nice. You have to rethink your logic and stay sharp until the end. Lovely!!
