The purpose of this football game and skill is to keep the ball in the air as long as possible without it touching the ground. Do not juggle with one ball is not that easy! Proof!
The contact between the mouse and the ball can boost up to it. Many bonuses are possible by rotating the mouse cursor around the ball (once or twice). Combinations of these rotations chained one after the other providing additional bonuses, up to 300 points with three sequences of double rotation in a row.
