Rovio introduced the game to iOS and Android's Google Play on Thursday. Rovio has confirmed in a message posted to Twitter that in less than three days of availability, the company has seen more than 10 million downloads. Angry Birds Space takes the familiar birds versus pig battle into space, where the gravitational pull of Earth does not apply and each planetary body has its own gravitation. This changes the gameplay from the ground up, allowing different combinations and taking some more time to calculate the right trajectories for the space birds.
