Bubble Shooter is based on a 1994 arcade game called Puzzle Bobble (alternatively titled Bust-a-Move). The aim is to make combinations of three or more matching bubbles with your bubble cannon. This will cause the bubbles to pop and vanish. If you miss, more bubbles will trickle down. If the bubbles sink to the bottom of the field, you lose the game! The bubbles come in all kinds of cheerful colors and more new colors will appear as you play. The more different colors, the harder it becomes to create bubble combos though.
