Untangle Deluxe

Untangle Deluxe is a logic puzzle game where you have to untangle a cobweb in such a way that none of the lines intersects with any other one. The cobweb can be untangled by moving balls: green balls can be moved an unlimited number of times, red ones can be moved just once and black ones cannot be moved at all. Blue holes must be illed with balls. The game is extremely simple, but solutions are not always obvious.
