Zwingo

Zwingo is a simple but very addictive game that is similar to marbles. However, instead of trying to shoot balls out of the circle, you want to keep the one ball in the circle! There is one large ball that sits in a circle. At least part of the ball needs to stay within the circle for the game to continue. Black balls will come at it from all sides, trying to knock it out of the circle. You control a ball that you can use to knock a black ball out of the way and off the screen. Move your mouse on the screen to control the ball and move it around.
