aim and shoot shoot bubbles so that they attach to other bubbles, creating three or more of the same color to clear them clumps. The more you take down the foam with a single shot, the more points you will score. If you are not taken to remove any air bubbles made ??a mistake, a new line of bubbles will sometimes appear. The game will end when either you clear the board or when the bubbles have reached the bottom of the screen.
