There can be no draw in this game, either you clean all the bubbles off, or they move all the way down on you. Various skill levels differ by the number of shots that you are allowed to fire without success. The number of misfires allowed before bubbles will advance again, is shown in the bottom left corner. If your shot fails to detonate any bubbles, you get a foul, and when there are several fouls, a new line of bubbles appears at the top.
It is well worth trying to arrange such avalanches, as they will give you ten times more points than ordinary bursts. Besides, those bubbles that fell apart from the rest will explode too. The more bubbles blow up at one shot, the increasingly more points you gain (six ones at one shot is better than two three-bubble shots). Point your mouse to where you want the next bubble to go (the arrow at the bottom will indicate that direction), and click to fire the shot. You shoot at them with more bubbles, and when three or more of the same color come together, they all explode. Your goal is to clear all the bubbles from the board, scoring as many points as possible.
