Logic Masters Deutschland e.V.

I have been working with interacting Whispers and Renbans with some dots added - this is the fourth puzzle of my explorations. The first was Dancing in a ring with German Whispers. This is a highly rated and elegant construction with clean and crisp logic, much of which will be familiar.

I then set a rather harder puzzle with Dutch Whispers (I think the logic has a family resemblance) N is for Naomi. Although people have found it much more difficult, as a setter I constructed it from very similar ideas - the change in the whispers loosens the constraints, but similar sharp questions guide the solve path

The third puzzle was rather different: Whisper, who dares?. It has some similarities with the previous two, but also some novel logic. There are different ways of approaching German whisper puzzles and this one relies noticing some details which may not be immediately obvious

This fourth puzzle has more in common with the first two - it was in fact the second one I set. It will again require clear thought and some care. I have put some solving notes in hidden comments and will be happy to give hints.

Normal Sudoku rules apply.

Adjacent numbers on a green German whisper line differ by at least 5.

On a pink Renban line the digits form a consecutive set with no repeats. The cross is a single 9-cell Renban

Numbers separated by a white dot are consecutive. Where two numbers are separated by a black dot, one is twice the other. (Partial kropki)
