A chain is created when at least 5 subsequent shots generate 5 subsequent explosions. At the 5th explosion a bonus of 100 points is awarded. The bonus for every subsequent explosion will be calculated by adding 10 to the previous bonus; the bonus for the 6th explosion would be 110, 7th would be 120, etc.Balls can be fired through gaps created along the curve to cause explosions onthe other side. The bonus ranges from 10 to 500 points. A large gap is worth 10 points, while something closer to the size of the ball is worth 500 (250 in Survival mode). If multiple gaps are cleared in a single shot, the best of the bonuses is multiplied by the number of gaps to figure the scoring bonus.

You can score points by shooting coins that appear in certain areas along the curve. If a coin is shot, a bonus of 1/6th the level's target score (rounded down to the nearest hundred) will be gained. In Adventure or Practice mode, the lowest possible coin value is 500 points regardless of the target score. But in Survival mode, the lowest possible value is 200 points. The target score is equal to the number of points needed to fill the Zuma meter.

Two additional bonuses are scored at the end of each level. A bonus will be given based on the distance from the last destroyed ball to the entrance of the skull's mouth. An award of 100 points per 60 pixels is given.

A second bonus is awarded for speed. The player's time to clear the level is pitted against a unique and static Ace Time. If your time is equal to or lower than the Ace Time, an award of 100 points is awarded. If the Ace Time is beaten (not tied) the difference, measured as a percentage between the two times, is multiplied by 25,000 and awarded in addition to the initial 100 points. If the time was not beaten, no bonus is awarded.
