12! (Gift for Christounet)
(Published on 17. January 2025, 21:23 by the_cogito)
For the last of my holiday batch of puzzles this year, as part of a recently community-run event called "Secret Satan", I was given the privilege of setting a puzzle for Christounet, who has kindly given me permission to publish it. I'm really happy with this puzzle and how it turned out, enjoy :)
Rules:
- Draw a totally connected 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.
- Letters represent a unique digit between 0-9. Within the grid, every line shape appears exactly 12 times in every possible orientation.

Thank you so much again for this wonderful gift ! I was honored to be your victim. Masterful construction, gathering everything I enjoy about U-Bahn, encoded clues, with a great variety of global and local deductions. And miraculous too ! I am still amazed it was possible to get such an elegant grid with that super restrictive ruleset. Take a bow, Satan !
