Move your finger to aim and lift your finger to shoot. If you match at least three bubbles of the same color, they'll pop. Your goal is to pop the star rainbow bubble before the bubbles overflow and time runs out!

Keep an eye on the bubbles that'll help you: Bomb bubbles will clear the surrounding bubbles, lightning bubbles will clear an entire row, clock bubbles will slow down time, and one rainbow bubble will give you three rainbow bubbles, which will pop any color of bubbles.
