The number of shots between each drop of the ceiling is influenced by the number of bubble colors remaining. After every few shots, the 'ceiling' of the playing arena drops downwards slightly, along with all the bubbles stuck to it. If a bubble touches identically-colored bubbles, forming a group of three or more, those bubbles-as well as any bubbles hanging from them-are removed from the field of play, and points are awarded. The fired bubbles travel in straight lines (possibly bouncing off the sidewalls of the arena), stopping when they touch other bubbles or reach the top of the arena. After clearing the arena, the next round begins with a new pattern of bubbles to clear. Bubbles will fire automatically if the player remains idle. The objective of the game is to clear all the bubbles from the arena without any bubble crossing the bottom line. The color of bubbles fired is randomly generated and chosen from the colors of bubbles still left on the screen. At the bottom of the screen, the player controls a device called a 'pointer', which aims and fires bubbles up the screen. At the start of each round, the rectangular playing arena contains a prearranged pattern of colored 'bubbles'.
