Angry Birds Friends is a popular social puzzle game that allows players to team up with their Facebook friends to defeat the greedy pigs who have stolen their precious eggs. Developed by Rovio Entertainment, Angry Birds Friends is available on both iOS and Android devices.

In this game, players use slingshots to launch a variety of angry birds at the pigs' structures. The ultimate goal is to destroy all the pigs and their structures with as few birds as possible to earn high scores and stars. Each level has a different layout, and the pigs become increasingly difficult to defeat as the player progresses.

The game also features a variety of power-ups that can be used to help players defeat the pigs. These power-ups include explosive birds, birds that split into multiple birds, and birds that can change direction in mid-flight. Players can also earn coins by completing levels and daily challenges, which can be used to purchase additional power-ups.

One of the unique features of Angry Birds Friends is the ability to compete with friends in weekly tournaments. Players can challenge their Facebook friends to see who can earn the highest score on a set of levels. The top players on the leaderboard at the end of the tournament win rewards such as power-ups, coins, and new bird characters.

In addition to the weekly tournaments, Angry Birds Friends also has a variety of special events throughout the year. These events often include new levels, power-ups, and exclusive rewards for players who participate.

Overall, Angry Birds Friends is an engaging and addictive game that offers hours of puzzle-solving fun. With its social features, players can challenge their friends to see who can achieve the highest score and earn bragging rights as the ultimate Angry Birds champion.
