There are bonuses for collecting coins (usually through gaps), for causing explosions through gaps of other balls, and for having a streak of always causing an explosion with each consecutive ball (coins and chainbonuses are a quick way to fill the bar). Time bonuses are also awarded if a player completes the level within ace time - ranging from thirty seconds to four minutes depending on the level.
Four different types of power-ups show up in balls, which can be activated by exploding the ball with the power-up. The backwards ball pushes the furthest-out chain (depending on if all of the balls are connected) backwards for a short length of time. The slow-down ball slows the speed of the chain of balls for a short length of time. The accuracy ball allows quicker shots and points an arrow at where the ball will be shot (this stays active for about the same amount of time as the slow-down ball; however, size of balls must be considered). The explosion ball explodes all of the balls within a small radius of the ball at the spot and time of its explosion. If not exploded quickly, power-up balls will return to their regular state after some time.
