Pop Adventure is a bubble shooter: you fire coloured bubbles up into a cluster, and three or more of a colour touching each other pop and fall away — along with anything they were holding up.
That last part is what separates good play from average. Detaching a whole section by removing its anchor clears far more than popping bubbles one group at a time.
By popping the bubbles that anchor them to the ceiling. Anything left unattached falls, so removing an anchor clears far more than popping the same number of bubbles at the bottom.

Yes — tap to aim and fire. Nothing to install.
