Modular U-Bahn
(Eingestellt am 12. Juli 2025, 00:00 Uhr von cyddrdrd)
Thank you Maddie and MonsieurTRISTE for testing it!
Rules
- Normal sudoku: Fill the grid with digits 1-9, so that no digit repeats in the same row, column, or 3×3 box.
- U-Bahn: Draw a totally connected loop network through the centers of some cells in the 9×9 area. The network may branch or turn, but may not have any dead ends. Clues outside the grid indicate how many times the corresponding line shape (cross, branch, straight line, or turn) appears in that row/column, regardless of rotation.
- Interaction: Assign line shapes to digits (irrespective of rotation) as follows:
- Corner = 1
- Straight line = 2
- Branch = 3
- Cross = 4
Penpa+
SudokuPad
Lösungscode: For each column except the last, from left to right, the number of lines leading right from that column; followed by row 3. (17 digits in total)

Exceptional puzzle! Curious about the setting strategy for U-bahns. Two thoughts: Would a 6x6 snack be interesting possible? What about connecting to juggler's tessellation grid?

rdrd: good idea! I might try those later. Thanks!

Awesome! I will admit that I was skeptical to see such an ambitious ruleset by a first-time poster, but I was thoroughly impressed by the variety of logic throughout and an extremely nice finish. Respect!

Impressive first puzzle. Was fun to solve and luckily more approachable than the ones of setters who inspired this puzzle. :-)
Thanks

@SparkNights: The network doesn't have to pass through every cell in the grid, just only some of them.

How does 4s and 8s in edge cells work?

Wow, lots of beautiful interactions between two genres, super impressive achievement for the first puzzle! (you should add 'sudoku' tag into this as well)
At first it didn't seem like it'd actually resolve at the end, but then I was proven very wrong there x)

rdrd: Thanks for your suggestion! Tag added :)
