(Published on 16. May 2025, 16:56 by KNT)
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.
Orthogonally adjacent cells cannot contain the same line shape. Empty cells may touch freely.
