Snackdoku-bahn (ft. KNT)
(Published on 6. April 2025, 18:53 by the_cogito)
Rules:
Within the left U-bahn grid, 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 U-bahn grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, turn, or empty cell) appears in the corresponding row or column, irrespective of the line shape's rotation.
Fill the right Sudoku grid with the digits 1-4 such that no digit repeats in any row, column, or box.
Each cell in the Sudoku grid corresponds to a 2x2 region in the U-bahn grid. Digits in the Sudoku grid indicate the number of cells that the U-bahn loop network passes through in the corresponding 2x2 U-bahn region.
Solve on Penpa+

Solution code: For every row except the last, the number of line segments extending down from that row within the U-bahn grid.

I’m not that familiar with U-bahn puzzles, but still was able to figure my way through it. Very fun and neat solve!

Very fun little puzzle. Impressive to get such a clever and smooth solve out of so few clues.

Lovely puzzle!
If you're interested, I've also made a sudokU-bahn, but with a 4x4 "octoquadri" mapping to a 12x12 U-Bahn. https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000MH5

Nice little snack! Thanks :)
If you are interested, I made a puzzle with the same ruleset a while ago, with a 6x6 sudoku CC and U-bahn
