The game is pretty easy to start.

You need to guess four distinct number ranged from 1 to 9. The system will respond a message, which formatted as: a2b1. This means you have 2 right numbers in the right positions, and also 1 right number in the wrong position.

You could not win the game unless you have all those four numbers right and also located in the right position.

Required:
Android OS: 2.3.

Set up hardware device (Samsung Nexus S) for developping on Ubuntu 10.04+

The most of the steps are from official android develop link.
