Normal Sudoku rules apply.

On an orange line adjacent digits must differ by at least 4 (standard Dutch whisper)

Digits on a pink Renban line form a consecutive sequence with no repeats.

If two digits are separated by a black dot, one must be twice the other. Two digits separated by a white dot are consecutive. (partial Kropki)

Here is the Sudokupad link: Counting is hard

Since I imitated myself for Scojo's 2026 imposter prompt with Counting on incompleteness, I had to complete the imitation by making a Dutch Whisper cousin of the original. As with previous examples, the Dutch Whisper version is rather harder - if you catch on to the right thing it is not brutal, and as with previous pairs I have set, the logic does have a family resemblance. But the extra looseness of the whispers has to be taken into account. I would highly recommend solving the previous puzzle first.
