KISS - Keep it simple and short. Simple: Simply pop the bubbles or fling them out of the screen. Short: Less than 1MB to download.
The goal of the game is to pop all bubbles within the time limit. You will get score based on the number of popped bubbles, their size, and the time elapsed. You can also fling the bubbles out of screen but you can't score for it. You may change the time limit from TIME SETTINGS in the menu bar.
