How to play Lineloop
- A clue counts how many of that cell's four edges are used by the loop. A 0 rules out all four; a 3 uses three.
- Every point touched by the loop has exactly two lines, so the route cannot stop, branch, cross or form a second loop.
- Tap an edge to cycle blank, line and X. Crosses are optional notes: a complete correct loop finishes without every unused edge marked.
Your first useful move
A zero rules out all four edges around its cell. At each dot, a loop can use either zero or two edges, so an existing line often forces its continuation.
