How to play
A tangled graph is displayed with nodes and edges. Some edges cross each other — your goal is to drag nodes until no edges cross.
The graph is always untangleable — a valid planar arrangement exists!
Press CHECK to verify your arrangement. Crossing edges will be highlighted in red.
You have 4 checks. Untangle it before you run out!
