This game is an example of object oriented programming. The goal of the game is to completely cover both the left and right walls (black rectangles) with the balls (red and blue circles) before either the top or bottom walls are completely covered by the balls. The blue balls drop from the top and the red balls rise from the bottom. When selected, the blue balls will go to the right wall and the red balls will go to the left wall.

Click on the balls to send them to the walls. The balls must be completely within the dark grey square around the mouse in order to send them to the walls.
