Quad Renban Killer
(Published on 13. January 2024, 15:38 by PDN777)
Normal sudoku rules apply. Digits in a quadruple circle must appear in the surrounding cells. Digits on a purple renban line must be consecutive, can be in any order, and must not repeat. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. I think this puzzle is 2.5 - 3 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

Fun puzzle! Knowing the tricks of renban lines with required digits based on lengths, 2 stars is an appropriate difficulty
** Yes that knowledge was used extensively throughout the puzzle! Thanks!

I liked how the quads seemed useless but actually forced the digit placements. There were also lots of other interesting deductions.
** Yes the little quads did good work for us! Thanks!
