This multiplayer social video game is based on a simple concept:

You play as a plane, and the goal is to take passengers from one place to another. The way to reach the destination is to gain altitude. The higher you go, the more passengers you pick up. You can also watch the rate increase as your rate of climb increases, or you can skip the climb and go straight to the destination.

What makes this game special is the way you interact with the game. As you play, you can talk to other players and even make friends. The more passengers you pick up, the more money you can earn.
