Landvermessung U-Bahn
(Published on 27. June 2024, 01:47 by KNT)
A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.
A clue inside the grid indicates the length of the smallest loop (that does not touch or cross itself) on the network that touches all non-empty cells surrounding the clue. If the clue is an infinity sign, then no such loop exists.
A 6x6 example is provided:
Solution code: For each row from top to bottom except the last, the number of lines leading down from that row.

Brilliant puzzle! Really put a KNT spin on this rather unique combination of genres.

Avoiding mistakes with this ruleset is really tough, and it was often difficult to see how it could have a solution. Lots of cool and unexpected moments

@jessica6, other solvers have submitted codes after I have fixed it, could you leave your code in a hidden comment?

@KNT Damn!! Now I finally have the solution, WITH that ambiguity, and both solution codes are no longer valid because the puzzle has changed.

Cool puzzle, the infinity clues are indeed used well :)

Despite Landvermessung being a super niche genre, after the opening this felt like one of the most intuitive solves that involved an U-Bahn. Lovely!

Very nice, some neat logic especially with the infinity clues!
