Normal sudoku rules apply.
Each line in the grid is either a German whispers line or a renban line. Which is which is to be deduced by the solver.
Whispers: Digits which are adjacent on a German whispers must differ by at least 5.
Renban Lines: Digits on a renban form a set of non-repeating, consecutive digits in any order.

As the others have said, this is one of those great puzzles where it really is just about asking the right question at the right moment for the deductions to flow. Wonderful!
