(Eingestellt am 28. Juni 2025, 06:28 Uhr von wooferzfg)

If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.

Rules

Draw a totally connected loop network through the centers of some unshaded 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.
