A simple to pick up game, but hard to lay down. You have some flying bubbles, grouped in one piece. The piece can contain either 2, 3 or 4 bubbles according to the level. Your goal is to clear the screen from bubbles, so to pass to the next level. The bubbles explode when three or more come close to each other. Only flying bubbles can commence a reaction. So in order to make reactions, you have to land bubbles on similar ones or nearby similar ones. The new generated bubbles will contain only bubbles found on the screen. So in time number of different bubbles should decrease.Whenever you land the bubbles a new set of bubbles will appear automatically at the bottom of the screen and starts moving automatically.
