The goal of the game is to make wheels explode all the wheels on the level by filling them up with the same color ball. You can transfer balls from one wheel to another along tracks, and you can still fill up wheels after they have exploded. The gameplay starts out basic, and gets absolutely frantic due the time bar that's always going down. It resets as soon as a new ball appears, but as long as there are no places available in the wheels, the ball will bounce back and forth on the top of the screen. This requires you to constantly rotate and shift balls around, all while trying to bring the colors together. This game is not for the feint of multitasking! As the game progresses, you come across increasingly difficult levels that will both challenge and frustrate.
