This puzzle got rejected from the sudoku adventure series because it is slightly too hard for that format. But I'm very happy with it and decided to release it here instead. As always, thanks everyone for testing and I hope you enjoy!

Normal 6x6 Sudoku rules apply.
Renban Lines: Digits on a pink renban line don't repeat and must form a single consecutive run (like 234) when sorted.
Quadruples: Each digit in a circle must appear at least once in the 4 cells touching that circle.

Very nice! Good morning solve that required the coffee to kick in before the logic became visible. :)

I concur with macintux, familiar rules to me and yet I've still discovered new things here.

…in which I learn renban lines can have more subtle effects than I had previously considered. Very nice.

I would very much enjoy seeing this puzzle on the adventure series, but I get why it might be a bit too difficult. Lovely puzzle anyway
