Puzzle Bubble / Bust-a-move    is a puzzle game from Taito
The object of the Game is to shoot colored balls at angles that bounce off a 
wall and link up other color bubbles. When 3 or more balls of the same color are 
connected then they are removed from the screen, including all bubbles that hang 
below them. In a one-player game there are 30 rounds to complete and in 
two-player mode the object is to clear your screen first. This is the first 
title in the famous Puzzle Bobble series.
