How to play Line Fill
Line Fill is a path puzzle. Each level is a grid with some open cells and some obstacles. Start on any open cell and draw a single line that covers every open cell exactly once.
The line cannot cross itself or pass through obstacles, so look ahead before you commit. Drew yourself into a corner? Drag back along the line to erase and try a different route.
There are 60 levels in five packs of twelve. You begin with a hint, and you can earn more by watching an optional video.
