Read Between the Lines (Build Your Own Puzzle)
(Published on 8. December 2021, 03:56 by tallcat)
Normal Sudoku rules apply
1. Circles represent one end of a Between line.
2. Circle digits give the length of the rest of the line including line cells and the other endpoint (e.g. 3 = 2 line cells + the other endpoint cell). The other endpoints are not circled digits
3. Line digits must fall between the two endpoints. Digits can repeat if allowed by other rules.
4. Lines may only move orthogonally, cannot cross, or share endpoints.
5. All between lines have at least one line cell.
6. Endpoints of the same between line may not be in orthogonally adjacent cells.
Example Puzzle
Can be solved online at f-puzzles or CTC
Solution code: Row 7 (Left to Right) followed by Column 6 (Top to Bottom). 18 digits, no spaces.

Exceptional setting, very consistent logical path throughout the solve, even till the very end.

One of my favorites from you, though I found this very tricky, despite this kind of puzzle being very in my wheelhouse

Very beautiful setting ! I had to start over 3 times because I thought I had broken it. Only I had misread the rules and thought the lines could not touch themselves... On the other hand, starting over made me appreciate even more the very subtle construction behind this puzzle ! Very well done !

This was hard for me, had to restart a few times to get it right eventually. Very nice puzzle, though.

Very nice! The opening felt rather more approachable than 4 stars, but it gradually upped the difficulty with some very nice interactions in there. Well done! :^)

I solved this one for 65mins and never feel stuck in any minute. Just a pure enjoyable journey of deduction. The interaction between Between Lines and normal sudoku is brilliant. Thanks!

Oww, what did my poor brain ever do to you? (Oh right, Carousel. Never mind.)
Exceptional puzzle! Very much tested my limits as a solver, but worth every step.

Intriguing and challenging from start to finish. Another one I'd strongly recommend fo CTC.
