Bubble Shooter is one of the most-played casual games ever made. A cluster of coloured bubbles hangs at the top of the screen; you fire bubbles at it from below, and any group of three or more of the same colour that forms pops — along with anything hanging beneath it.
That last part is the whole strategy. Popping a group that supports a large section drops the entire section, which is worth far more than clearing bubbles one cluster at a time. Bank shots off the side walls are how you reach the awkward supports.
Target the bubbles that support large hanging sections. Dropping a whole section scores far more than popping a cluster of three, and bank shots off the walls are how you reach those supports.
Any bubble not connected to the ceiling — directly or through other bubbles — falls and counts toward your score.
Yes — tap to aim and fire. Nothing to install.
