Aim and shoot bubbles to form groups of three or more of the same color. The larger the group, the higher your score. If your shot does not connect to a matching bubble, you receive a strike. After several strikes, a new row of bubbles is added at the top. The game ends if the bubbles reach the bottom of the screen.
On a computer – Use your mouse pointer and left-click to shoot the bubble accurately.
On a mobile device – Tap on the screen with your finger to launch the bubble.
