You’ll get points for combos-two or more explosions caused by firing a single ball-and you can collect power-ups by detonating special balls that appear in the chain, such as “Accuracy,” which gives you a special aiming beam in and increased firing speed, “Backwards,” which rolls the chain back up the track a bit, “Bomb,” which blasts everything in its path, and “Slowdown,” which makes the chain slow down.

Two or more explosions caused by firing a single ball nets you points in Zuma, which also lets you collect power-ups like a Backwards ball.
