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 (3, 2, 1 in sequence). 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.
