Planarity. It's a puzzle. It's a kinda minimal puzzle, graphics-wise. There's an art to that, you know, making a puzzle that requires so little from technology and so much from our minds. Kinda maximal, fascinating-wise.

See the ball-like points? You can click on any of them and drag them to a new position. See those lines connected to the ball-like points? When you move the point they're connected to, they stretch. The puzzle: Move the balls. Stretch the lines. Until no line crosses any other.

Easy to understand. Easy to play with. And yet, remarkably challenging. Kind of the perfect formula for a good puzzle.

Caution, like all good puzzles, it can get very challenging, very rapidly. The first puzzle is way easier than the 9th. In fact, you can solve it in just one move. Can't you?
