Start with one tile and trace a line to the next, then the next. Each tile you pass over flips from black to white, or back again. Using only a single line, can you flip all the black tiles?
We know, it doesn't sound like much. You'll fly through the first set of levels with barely a hitch. Then you'll run into some snags. You'll realize that where you start and stop really matters. You'll notice that one wrong turn can make or break your solution later on. You'll discover that some puzzles require the line to overlap, or avoid some tiles altogether. You'll find that complexity lies under the surface.
