Use mouse pointer to move paddle. Try not to let the balls touch the bottom of the screen. Note: very hard to get all 3 balls to not touch the bottom. Note: may have to hit the green flag twice to start. I don't know why.
If you hit a ball with the paddle you get a point, and if a ball hits another ball you also get a point.A green button appears for 1 second every 10-20 seconds hit it with another ball for extra points.
