Shooting the ball is easy. You simply place your cursor where you want to aim. Then click and watch the ball launch toward your target. The tricky part is when the chain starts to coil in the spiral track. You might want to target the line behind the current one, but you risk hitting the one in front of you. To remove balls faster, look for several balls of the same color and shoot them. When you eliminate a sequence, consider if the balls around them are of the same color. This means the chain reaction will also eliminate those balls. This game is a pleasure to play and is easily addictive.

Expect the same spike in difficulty after the first two levels. The superficial changes do have their advantages, though. Its muted color scheme is easier on the eyes. The music is also less intrusive; you can leave it on as white noise instead of turning it off.
