Shoot the bubble at the bottom by clicking. Make lines or clusters of 3 or more of the same color. If you don't knock any bubbles off in a round, you will loose a life. Every time you loose all your lives, a new line of bubbles appears at the top and you get some lives again. Don't let the bubbles overflow the board. The multiplier of the points gets bigger after every successful shoot in a row, so the longer sequences you make the more points you get. There is no time limit in the game.
