Planarity portable offline version

A simple but addictive puzzle game – Unwind an entangled web so that no lines cross each other.

Move the web of balls around until the web is untangled. If you untangle a web, is it a web anymore? Or is it just string? Click and Drag the vertices to move them around and untangle the mess.

[ How to Play ]

Click on the little blue dots, which we call vertices, and then drag them to a new position. Try to arrange the vertices so none of the lines intersect. These lines are also called edges.

When none of the lines intersect, then click on the “Check Solution” button. If your solution is correct, you will go to the next level.

We call this kind of graph planar because it can be drawn (embedded) on the surface of a plane or sphere with no edges intersecting.
