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.

Neat little puzzle! I didn't struggle so badly in this one but I needed one or two observations to make a breakthrough, which made me think it's around low 3 diff I guess :)
