puzzle bobble

At the top of the rectangular playing arena, a number of balls 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 balls in a straight line. The ball, when fired, travels in straight lines, possibly bouncing off the side walls of the arena, before eventually coming to rest either touching one or more of the balls, or at the top of the arena.
