Pop on-screen balloons. 100 turns per game. Pop a group of 3 or more of the same color to earn points. Three balloons of the same color is worth 2^3 = 8 points. Four balloons of the same color is worth 2^4 = 16 points, a group of five of the same color is worth 2^5 = 32 points, and so forth. A group of 20 balloons of the same color, for example, is worth 2^20 = 1,048,576 points! Try to get a whole bunch of the same color to earn a ton of points. 

Two AI's (AI = Artificial Intelligence) provide help as you play. One AI explains the rules, while the other AI tells you your score, and provides encouragement (or scorn ). 

The game keeps track of your high scores as you play.

The iPhone version has less balloons than the iPad version, but each is challenging and fun to play. You can get very high scores on either device.
