Borrowing some elements from mini-golf and maze games and putting them together with a completely new style of control, Tractor Spheres is an easy game to learn but difficult to master. Strategically place Tractor Spheres with your mouse and then click start, and watch as the ball is attracted to the spheres whenever it has a line of sight. This property gives rise to interesting solutions to the levels in the game. There are 25 levels in all!
