Gameplay

In Angry Birds, the player controls a flock of multi-colored birds that are attempting to retrieve their eggs, which have been stolen by a group of hungry green pigs. In each stage of the gameplay, enemy pigs are sheltered by structures made of various materials such as wood, glass, 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 squash the pigs. 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 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 bird is available. 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. For example, a yellow bird speeds up, a blue bird fragments into three birds, a black bird explodes, a white bird can drop an egg-shaped projectile, a pink bird can trap objects in bubbles, a green bird boomerangs back, a giant red bird (similar to the original red bird) does more damage to structures than their smaller counterparts, and an orange bird expands and inflates. 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. If all of the pigs are eliminated after the last bird is launched, the level is completed and the next level is unlocked. If all of the birds run out and the pigs are not defeated, the level is incomplete 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 receive one, two, or 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.

Development

In early 2009, Rovio staff began reviewing proposals for potential games. One such proposal came from senior game designer Jaakko Iisalo in the form of a simulated screenshot featuring some angry-looking birds with no visible legs or wings. While the picture gave no clue as to what type of game was being played, the staff liked the characters, and the team elected to design a game around them. 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. 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. 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 and then stayed there for 275 days. The initial cost to develop Angry Birds was estimated to exceed €100,000, not including costs for the subsequent updates. For the iOS version, Rovio partnered with distributor Chillingo to publish the game to the App Store. Chillingo claimed to have participated in final game polishing, such as adding visible trajectory lines, pinch to zoom, pigs' grunts, birds' somersaults on landing. 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.
