The objective is to tap at the specified colored bubbles until they are gone. The levels start off easy and become progressively more difficult.
As users progress through the game the order of the colors to tap becomes important. The colors are tagged with numbers to indicate the order to tap. The numbers are sequential, but are not necessarily linear. The numbers can have a variety of patterns, odds, events, primes, etc.
The tap rate of the game is also computed. By looking at the scores view users can see their history of tap rates as they progress through the game.
