Use the paddle to hit the ball, or balls. You get points whenever a new ball appears and every second. A new ball appears every 30 seconds until there's 5. Goal: Don't let the balls touch the lava, and get the most points. If a ball hits the lava, the volcano will explode and you will lose. (The island is really unstable!)
