Puzzle rules
Normal Sudoku rules apply.
On a green line adjacent digits must differ by at least 5 (standard German 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)

This was my own puzzle for Scojo's 2026 imposter prompt. I am very pleased with it, but I got roundly trounced by my imposter, who made a really cunning and excellent puzzle developing some of the ideas I've been exploring, This one is, I think, very clean, if you see the logic the right way. If you are fighting it, there is something you haven't yet seen.
Lösungscode: Row 5

Well, reading your hidden message, for which a huge thanks, I guess I did find the intended path. Maybe I expected something easier that I missed, because of the 3 star difficulty at that moment. Thanks again for the great puzzle!

Very intriguing puzzle where you can see the relevant ideas very quickly. It takes deeper thought on those ideas before the interactions needed to advance materialize. Great from start to finish 3.5* range for me.

Took me just under two hours, but I did this at work, so with my undivided attention I reckon it’s probably a 90 minute job.

What a beautiful puzzle, Fool on Hill! I had the right approach from the very start, but the break-in was still slow going and really clever logic. Had to unwind a bit just on the cusp of cracking the thing open due to doing some logic backwards on r7c3, even though I had the correct idea for the solution path.
Brilliant construction. 91 minutes for me. Thank you for this
