U-Bahn Under Arrows
(Published on 7. April 2025, 05:57 by wooferzfg)
The rules for this puzzle are similar to a series by Zzzyxas. There is also a puzzle by KNT with similar rules.
If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.
The first diagram is a standard U-Bahn. Draw a loop network through the centers of some 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.
The second diagram is a 6x6 Latin Square. Place the numbers from 1 to 6 exactly once in every row and column. Numbers on arrows must sum to the number in the circle.
The third diagram indicates exactly how many times a cell of the Latin Square contains the given number and the same relative cell of the U-Bahn contains the given line shape.
Solution code: For each column in the U-Bahn grid except the last, from left to right, the number of lines leading to the right from that column

Incredible logic and construction, especially with so few clues.
(answer check didn't work for me, but the solution code did)

I hardly realized what to do with the clues. But when I found out, the puzzle was nice.
