Do you have anything urgent to do? If you do, you should not even think about playing Bubble Shooter Pro. Your goal is to remove all the bubbles from the board, scoring as many points as possible. Match 2 or more bubbles of the same color with the color of the ball you shoot to remove them.
The more bubbles you manage to blow up in one shot, the more points you gain. If you fail to detonate bubbles, you get a foul, and when there are several fouls, a new line of bubbles appears at the top.
