Unique Renbans
(Published yesterday, 15:45 by Phurba)
Rules:
- Normal Sudoku rules apply. Place the digits from 1 to 9 once each in every row, column, and 3x3 box.
- Anti-Entropy: No pair of orthogonally adjacent cells can contain digits from the same entropic set. The entropic sets are low (1, 2, 3), middle (4, 5, 6), and high (7, 8, 9).
- Unique Renban Lines: Digits on a purple line must form a set of consecutive digits in any order, without repeats. No two renban lines contain the same set of digits.
- Little Killer Arrows: The digits along each of the two indicated diagonals must sum to the same total which has to be determined by the solver.
Enjoy!

Yes, it took a second or two to figure out the correct tactic, but once found, the solution flowed very nicely. Excellent puzzle.

Ein großartiges, sehr schweres Rätsel. Vor allem sehr ungewöhnlich, da waren wirklich ein paar Schritte dabei, die für mich gänzlich Neuland waren. Wie man auf sowas kommt… ich kann da nur staunen!

Excellent construction! Very fun solve path and I really enjoyed how the unique renban lines rule participated. Thanks for sharing!

Brilliant puzzle! I loved the minimalistic setup, the solve path and the disambiguation by the little killers. I think the puzzle is less than 4 stars for difficulty: my solve time fits 2.5 to 3 stars. Thanks a lot!

Fantastic puzzle. The combination of entropy and unique renbans flowed very well.

Beautiful puzzle.
It took me a few minutes to realise what to do but once I did it flowed so smoothly and was a joy to solve.
