Die Renban-Linien sind sinnlos und überflüssig.

I reworded the description regarding the pink (Renban) lines, and the green (German Whisper) lines.

The suggestion some people have made is to specify a whisper-n line where n is the minimum difference. The other issue is colour - green tends to mean the standard line for the size of grid.

We should bring back naming whisper lines after countries, instead of assuming the green line is 3 for 6x6 and 5 for 9x9. Austrian Whisper Line, anyone?

Not hard at all except ... note that the normal whisper constraint for a 6x6 puzzle is a difference of at least 3 (not 5), and I carelessly assumed this was the case until I re-read the rules when I got stuck.
