Kill green pigs and revenge the theft of bird eggs in the physics-based puzzle video game called Angry Birds. This video pits angry birds catapulted from a large slingshot into various buildings, castles and structures in order to kill the green pigs and advance to the next level. Angry birds offers new challenges with each level that must be completed to move on to the next level.

The easiest way to complete each level is to watch videos and read advice from other players who have already conquered each level. This video game guide will allow you to quickly learn how to get three stars on level 2-20 in Angry Birds.

When level 2-20 first appears, take a minute to survey the landscape and plan your strategy. One green pig is fortified in a medium-size castle on the right-hand side of your screen. Two pigs are located behind T-shaped obstructions that are laid on their side.

From the slingshot located on the left side of the screen, launch your angry bird towards the green pig in the fortified castle. The goal is to have the structure collapse onto the other two green pigs on the ground so you do not have to fire a second shot.

Fire your second shot onto any remaining green pigs. A second shot may not garner you three stars, so you will likely need to replay the level to earn three stars by using only one shot.
