Short description of Wildball for Windows 21: WildBall is clone of classic Arcade game Jezzball.
The game begins in a large capture chamber with one ball bouncing around (Jezzball from Microsoft has two balls at begin) With a click of the mouse, you can build a new chamber wall and trap the balls in a smaller space. But be careful, if you don't build your wall completely across the chamber before it's hit by a ball, it won't withstand the impact.
