Puzzle Bobble (also known in the United States, Canada, and sometimes in Europe as Bust-a-Move) is an arcade puzzle game series created by Taito
and contains elements of Sega's Columns and Atari's Breakout.
At the top of the rectangular playing arena, a number of bubbles of various colours are placed in a prearranged pattern at the start of the level. At the bottom of the screen, the player controls the angle of a fixed cannon that fires semi-randomly coloured bubbles in a straight line. The bubbles, when fired, travel in straight lines, possibly bouncing off the side walls of the arena, before eventually coming to rest either touching one or more of the existing bubbles, or at the top of the arena.
If the bubble manages to come into contact with identically coloured bubbles, forming a group of three or more, those bubbles, and any bubbles hanging only from them, are removed from the field of play, and points are awarded depending on how many bubbles are removed from the screen at once.
