Three-Line Riddle
(Published on 28. November 2022, 23:35 by JeremyDover)
From me and Raumplaner, some more entropic lines (and friends!) from the Layers of Entropy puzzle pack!
Rules
Normal sudoku rules apply.
Entropic lines: Any set of three sequential cells along an entropic line must contain a low (1,2,3), middle (4,5,6), and high (7,8,9) digit. Digits may repeat on a line if allowed by other rules.
Kropki pairs: Digits in cells connected by a black circle have a 2:1 ratio. Digits in cells connected by a white circle are consecutive. Not all possible circles need be given, so there is no negative constraint.
There are three entropic lines in this puzzle whose position you need to determine. These three entropic lines connect the caged cells labeled A, B and C respectively. These lines must consist of vertical and horizontal line segments, may not cross other lines, and may not cross cell boundaries marked with black rectangles.
Continuing the entropic lines series with Raumplaner, this is puzzle #25.

Can a line touch itself?

JeremyDover: Yes, a line may touch itself, but it may not cross itself or other line.

The logic in this puzzle is incredible and was so much fun to solve. Definitely one of my favorites! The cell boundaries were a very nice touch to help direct where the entropic lines may be.
