' 'Angry Birds Friends' Takes Flight on Facebook'.

'Angry Birds Friends flocks to iOS and Android'. 'Angry Birds lands on Facebook a day early'. In March 2016, Angry Birds Friends had a special theme 'Year In Space' to commemorate the return of the American astronaut Scott Kelly and two cosmonauts after spending one year on the International Space Station. These usually include a special gimmick to make them unique, like 20 Halloween introducing zombie pigs, which spawn a extra pig to kill when a new one’s killed. The game's weekly tournaments sometimes feature levels based on the season, such as Christmas themed levels in December and Easter themed levels during Easter. In March 2013, Rovio added the episode named 'Pig Tales', which has fantasy-themed levels, for the Facebook version that features an all-new power-up and a mushroom hat that can be used in the in-game avatars. The levels were removed in December 2012.

The new levels showcased each member of Green Day as a green, bad pig and also featured Green Day's latest single, and an exclusive track. In August 2012, Rovio announced a partnership with the punk band Green Day, which led to 20 new levels of Angry Birds Friends on Facebook featuring all three members of the band. In July 2012, the episode 'Pigini Beach' was added to the Angry Birds Friends Facebook version.

In February 2012, the episode 'Surf and Turf' was added to the Angry Birds Friends Facebook version and it was also added to the original Angry Birds. In addition, the mobile version includes four power-up practice levels where there are infinite power-ups available for use. The top 3 winners each week earn in-game currency, called Bird Coins, which can be used to purchase power-ups or to acquire additional bird slingers. The game requires a login to Facebook to sync progress otherwise one can play without a Facebook account. Unlike the previous Angry Birds games, this game syncs progress with the Facebook version's weekly tournaments between the player, placeholder scores represented by Red and Chuck, and any of the player's Facebook friends who also play the game. The mobile version has six-level tournaments that change twice a week, but there are no episodes like other games or the Facebook version.
