Aim, shoot, and pop matching bubble groups.
Press Start. Drag on the field to aim. Tap Shoot to fire the ready bubble. A shot that makes a group of three or more of the same color pops that group. Bubbles no longer attached to the top fall. If any bubble reaches the lower danger line, the run ends. Clearing the cluster finishes the round.
Drag on the play area to aim. Tap Shoot to fire. There is a short lock after each shot so a double tap does not fire twice.
Match the color or the word before time runs out.
