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, turn, or empty cell) appears in the corresponding row or column, irrespective of the line shape's rotation.

A 5x5 example is provided:

I find u-Bahn totally totally unintuitive, so thank you for the more approachable puzzle. I've never been so happy to solve a 1 star!

Also my first ever U-Bahn! Much harder than a 1* "sudoku" for me due to unfamiliarity, but thoroughly enjoyable. The logic was very satisfying, and I'm looking forward to solving more of these! Thank you for the great introduction.

My first U-Bahn ! Even though I struggled a bit, the puzzle was still very enjoyable. Thanks
Ps, what U-Bahn do you think is a perfect mix of approachability (?)and logic variety ?

Seeing a 1* KNT puzzle is incredibly surreal. Really enjoyable snack puzzle!

This is a great variant idea, looking forward to solving (and setting) more puzzles with it!
