U-Bahn
(Published on 18. May 2025, 09:07 by wooferzfg)
If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.
Draw a totally connected loop network through the centers of some unshaded cells, which may branch or turn, but may not have any dead ends.
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.
Solution code: For each row except the last, from top to bottom, the number of lines leading down from that row
