Eggsteroids

Eggsteroids is an episode of Angry Birds Space that is the Space version's equivalent of the Golden Eggs episode of the classic Angry Birds. Golden Eggsteroids are found within levels themselves. When an Eggsteroid is obtained, the user is transported via a wormhole to the Eggsteroid level. When the level is completed/player gives up, he/she will be transported back by wormhole to the level where the Eggsteroid was. From that moment, the player can freely access the Eggsteroid level by going to the Eggsteroid world in the episode selection screen. The background of the eggsteroids episode has a large egg-shaped planet in the middle with eggsteroids floating all over the place. The background also has a yellow sky and stars.

Eggsteroids is the only episode in Angry Birds Space to have levels with YELLOW gravitational force fields instead of BLUE gravitational force fields. The only Eggsteroid level with BLUE gravitational force fields is the Samsung Bonus Eggsteroid.

Locations
Each Eggsteroid level revealed so far except one is an homage to a classic video game.

Gameplay
Unlike Golden Egg levels in Angry Birds and Angry Birds Seasons, the Eggsteroid levels can be completed for one to three stars. However in newer released updates of Angry Birds and Angry Birds Rio you are now able to earn three stars and features the same setup as, average Angry Birds levels. This gameplay is similar to the Trophy Room episode Angry Birds Rio.
