Cold Sauerkraut (Nabner Thermo Sudoku)
(Published on 24. August 2023, 17:47 by Silverstep)
Thanks to Zetamath for inventing nabner lines, Rangsk for adding Nabner to the fPuzzles integration scripts, and BremSter for the tutorial videos of how to use Rangsk's scripts.
Thanks for MicroStudy for testing and calling this one a banger.
If you're already familiar with nabner lines, you can play this puzzle here. Otherwise, you can read the full ruleset below.
Normal Sudoku rules apply. Place a digit from 1 to 9 in every cell such that no digits repeat in a row, column, or bold 3x3 box.
Normal Thermo variant rules apply. Digits on a gray line form a strictly increasing sequence starting from the big circle.
Normal Nabner variant rules apply. Two digits that share an olive-colored line must have a difference of at least 2. For example, if one such line contains a 4, the digits 3/4/5 cannot appear elsewhere on that line.
Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. There is no negative constraint.

Cool puzzle - got to it at last: tough but fair, once I worked out what was going on with lots of interesting deductions.

Gosh, this puzzle hurt my brain towards the parts around box 4 and box 7 but after that, the solve became smooth again.
Lots of interesting ideas in this one, thanks and congrats for a nice first puzzle on here!
