U-Bahn (6x6)
(Published on 15. April 2025, 17:13 by the_cogito)
I set this a while ago, and recently showed it to some "U-bahn" people who said I should publish it, so I am. Deceptively tricky for its size, especially for those less familiar with the genre. I hope you enjoy.

- A digit 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.

Very fun little puzzle. Small, but with some cool logic in there. Impressively minimal as well.
