Additional bubbles are typically added to the game board when one or more launches are made without making a match. Players earn points by creating groups of bubbles that match and disappear. The goal is to clear the bubbles from the screen by matching three or more bubbles of the same color. They have become a popular and addictive form of casual gaming. Bubble games are games where players aim and shoot bubbles at a cluster of bubbles at the top of the playing screen.
