Loops

Draw a single closed loop along the grid lines. The loop never crosses itself, never branches, and forms one unbroken path.

Each numbered cell tells you exactly how many of its four edges the loop uses. A 0means none of that cell's edges are part of the loop. Blank cells can have any number of edges.

Click an edge to cycle it: a line, then a cross (definitely empty), then clear. Crosses are just notes to yourself. Every daily has exactly one solution.
