In Angry Birds, the player controls a flock of multi-colored birds that are attempting to save their eggs from green-colored pigs.[13] In each stage of the gameplay, the pigs are sheltered by structures made of various materials such as wood, glass,[14] and stone resembling children's toy building blocks. The objective of the game is to eliminate all the pigs on the level. Using a slingshot, players launch a limited set of birds with the goal of either striking the enemy pigs directly or damaging their surrounding structures, causing the blocks to collapse and pop the pigs.[15] The player must set the angle and force of the bird's travel by pulling back on the slingshot (using intuitive touch-controls in the mobile versions). The launch process is quick and casual, with no visible trajectory data, and a player simply selects a point in the X-Y field behind the launch post from which the virtual slingshot will be released. In various stages of the game, additional objects such as TNT crates and rocks are incorporated into the structures, and power-ups may be used to enhance the birds to attack hard-to-reach pigs. Also hidden in the levels, players can unlock bonus levels by collecting golden eggs.
There are several different types of birds used in the game, distinguished by their color and shape. In the earliest levels only the basic red cardinal whose name is Red is available.[13] As the player advances through the game additional types of birds become available. Some birds are effective against particular materials, and some have special abilities that may be activated by the player while the bird is airborne.[15] For example, Chuck, a canary speeds up; Bomb, a loon explodes, hence the name; a bluebird named Jay fragments from his siblings, Jake and Jim; a Leghorn hen called Matilda can drop an explosive egg-shaped projectile; a galah named Stella can trap objects in bubbles; Hal, an emerald toucanet boomerangs back; a giant cardinal named Terence, appears and functions similarly to Red, but deals more damage than his smaller counterpart; and a Jamaican oriole named Bubbles expands and inflates.[13] The pigs also vary, with hardiness relative to their size. Small pigs are weaker and are easily vanquished by direct hits or by debris from the damaged structures, while larger pigs are able to withstand more damage before succumbing to defeat. In addition, some pigs wear hats or armor, making them even more resistant to damage.
Each level starts with the quantity, types, and firing order of birds predetermined.[13][15] If all of the pigs are eliminated after the last bird is launched, the level is cleared and the next level is unlocked.[13] If all of the birds run out and the pigs are not defeated, the level is failed and must be repeated. Points are scored for each pig defeated as well as for damage to, or destruction of, structures, and hefty bonus points are awarded for any unused birds. Upon completing each level, players can receive up to three stars depending on the score received. Players are encouraged to repeat any previously beaten levels in which the full three stars weren't awarded in order to fully master them and earn the full three star rating.
In early 2009, Rovio was in a state of bankruptcy; the staff began viewing proposals for potential games. One such proposal came from senior game designer Jaakko Iisalo[16] in the form of a simulated screenshot featuring some angry-looking birds with no visible legs or wings.[17] While the picture gave no clue as to what type of game was being played, the staff liked the characters,[17] and the team elected to design a game around them.[18] In early 2009, physics games, such as Crush the Castle, were popular flash-based web games, so the Rovio team was inspired by these games.[19][20] During the development of Angry Birds, the staff realized the birds needed an enemy. At the time, the "swine flu" epidemic was in the news, so the staff made the birds' enemies pigs.[16] Angry Birds was the studio's 52nd produced game and on its initial release, the game did not sell many copies. After Angry Birds was a featured app on the UK App Store in February 2010 and quickly reached No. 1 there, it reached the No. 1 spot on the paid apps chart in the US App Store in the middle of 2010, staying in that milestone for 275 days.[21][22] The initial cost to develop Angry Birds was estimated to exceed €100,000, not including costs for the subsequent updates.[17] In terms of publishing for the iOS version, Rovio partnered with distributor Chillingo to publish the game to the App Store.[23]
Chillingo claimed to have participated in final game polishing, such as adding visible trajectory lines, pinch to zoom, pigs' grunts, birds' somersaults on landing.[24] Since then Rovio has self-published almost all of the later ports of the game, with the exception of the PSP version, which was produced under license by Abstraction Games.
When Rovio began writing new versions of the game for other devices, new issues came to light. As the team began working on a version for Android systems, they observed a large number of configurations of device types and versions of the Android software.[16] The number of combinations of software version, processor speed and even user interfaces was significantly larger than that for the iOS version.[25] Ultimately, the team settled on a minimum set of requirements,[16] even though that left nearly 30 types of Android phones unable to run the game, including some newly released phones.[25] It was released on October 15, 2010. One month after the initial release on Android, Rovio Mobile began designing a lite version of the game for these other devices.[25]
In early 2010, Rovio began developing a version of Angry Birds for Facebook.[26] The project became one of the company's largest, with development taking over a year.[26] The company understood the challenges of transplanting a game concept between social platforms and mobile/gaming systems. In a March 2011 interview, Rovio's Peter Vesterbacka said, "You can’t take an experience that works in one environment and one ecosystem and force-feed it onto another. It's like Zynga. They can’t just take FarmVille and throw it on mobile and see what sticks. The titles that have been successful for them on mobile are the ones they’ve built from the ground up for the platform."[26] The Facebook version incorporate social-gaming concepts and in-game purchases and entered beta-testing in April 2011;[26] the game became officially available on Facebook in February 2012 as Angry Birds Facebook (later Angry Birds Friends).[27]
Improvements for the game include the ability to synchronize the player's progress across multiple devices; for example, a player who completes a level on an Android phone can log into their copy of the game on an Android tablet and see the same statistics and level of progress.[28]
