Race your opponent to tap all your gems first! You can play against the computer to see how many levels you can get through, but the real fun is two-player. Connect to another Android (2.1 or higher) device over Bluetooth and challenge your friends, family, and congressmen to a gem-tapping battle.
Remember to keep your phones fairly close to each other (20 feet) when using multiplayer.
Tested so far on the following:
Samsung Captivate (2.1 and 2.2)
G1 with Cyanogen 2.2
Recent changes are just for 1 player mode.
