If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
When is your turn, click on a bubble to inflate it a bit. When a bubble is pumped up to the maximum, it will pop, changing the color of the 4 surrounding bubbles: left, right, above and below. And the value of each of the 4 surrounding bubbles will be increased by one.
