Pathdoku
(Published on 31. March 2025, 11:29 by Andrewsarchus)
Rules:
- Latin Square with paths instead of digits
- Paths travel orthogonally through cell centers.
- Each cell can contain one of 12 distinct path configurations:
━, ┃, ┛, ┗, ┓,┏, ┳, ┻, ┣, ┫, ╋, empty - Paths connect adjacent cell centers, so cells must match at their common edge.
For example, ━ and ┃ cannot occur in orthogonally adjacent cells. - Some cells on the edge of the grid will have path segments which cross the grid border. The gray area around the outside of the grid is provided to allow these segments to be drawn.
- Fill the 12x12 grid so that each of the 12 path configurations occurs exactly once in each row, column, and cage.
- The numbers, 0 to 4, on some vertices count the number of edges at that vertex which are crossed by a path segment.

Super cool opening logic! A bit of a brutal step somewhat early on, but what follows is a super clean and interesting exercise in scanning and U-Bahn deductions. Thanks :)
