Pop touching bubble clusters and drop the rest.
Tap or click a bubble in a matching cluster. Single bubbles do nothing. Use Start and Restart.
Clear as much of the board as you can. The round ends when no group of two remains.
Bubble Pop is a grid-based matching puzzle. Bubbles sit in a packed field. A group is two or more neighbors of the same color. Tap that group and it bursts; bubbles above drop into the gaps. Singles do nothing. You keep clearing until the board is empty or no group of two remains. The shape of the field changes after every pop, so a greedy first tap can isolate colors you needed later.
Aim and time five penalty kicks.
