Bubble Number is the best free online Bubble Shooter game. Combining two popular arcade mechanics - virus games and marble popper, this game will keep you entertained for hours. Shoot bubbles to make groups of three or more of the same color. Each shot changes the group's color and increases the numbers within. Be careful not to let the bubbles touch the bottom of the screen, as you can only pop the bubbles featuring 5. With a limited number of turns, use helpful options such as changing the order of the balls or blasting the lowermost row of bubbles. Clearing the board earns you bonus points and raises your skill rank. If you're a true fan of online bubble games, you won't want to miss this exciting twist on a classic arcade game.
