The gameplay is very simple. You start with a set of bubbles. Tap the
screen to add a bubble. You can multitouch to create several bubbles at
the same time. Every time you add a bubble, a ripple forms and expands
outward from the center of the bubble. Whenever a ripple contacts a
bubble, the bubble is dragged along with the ripple a little bit, but the
bubble remains. If two ripples reach a bubble at the same time, the bubble
bursts. The game ends when you run out of bubbles to add and all the
ripples fade away.
