** 36 Amazing levels **
The main goal is to untie all the lines (make green) by dragging points. If the all lines are untied, the level will be completed.
When a line goes on top of another line, they will turn into red. Your job is to place all the points in a way where no lines cross each other. This way, all the lines will turn into green color and the level will be finished.
