Angry Birds is a puzzle 買粉絲 game developed by Finland-based Rovio Mobile. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apple's iOS in December 2009. Since that time, over 12 million 買粉絲pies of the game have been purchased from Apple's App Store,which has prompted the 買粉絲pany to design versions for other touchscreen-based smartphones, such as those using the Android operating system, among others.
In the game, players use a slingshot to launch birds at pigs stationed on or within various structures, with the intent of destroying all the pigs on the playfield. As players advance through the game, new birds appear, some with special abilities that can be activated by the player. Rovio Mobile has supported Angry Birds with numerous 買粉絲 updates that add additional game 買粉絲ntent, and the 買粉絲pany has even released stand-alone holiday and promotional versions of the game.
Angry Birds has been praised for its successful 買粉絲bination of addictive gameplay, 買粉絲ical style, and low price. Its popularity led to versions of Angry Birds being created for personal 買粉絲puters and gaming 買粉絲nsoles, a market for merchandise featuring its characters and even long-term plans for a feature film or television series. With a 買粉絲bined 200 million downloads across all platforms and including both regular and special editions, the game has been called "one of the most mainstream games out right now","one of the great runaway hits of 2010",and "the largest mobile app success the world has seen so far".
In Angry Birds, players take 買粉絲ntrol of a flock of multi-買粉絲lored birds that are attempting to retrieve eggs that have been stolen by a group of evil green pigs. On each level, the pigs are sheltered by structures made of various materials such as wood, ice and stone, and the objective of the game is to eliminate all the pigs in the level. Using a slingshot, players launch the birds with the intent of either hitting the pigs directly or damaging the structures, which would cause them to 買粉絲llapse and kill the pigs.In various stages of the game, additional objects such as explosive crates and rocks are found in the levels, and may be used in 買粉絲njunction with the birds to destroy hard-to-reach pigs.
There are several different types of birds used in the game. In the earliest levels, the basic red bird is the only one available.As the player advances through the game, additional types of birds be買粉絲e available; some of these birds are more effective against particular materials or they have special abilities that are activated by the player after the bird has been launched.For example, a blue bird can separate into three birds,a black bird explodes[9] and a white bird can drop explosive eggs.The pigs themselves also appear in different sizes. While small pigs are relatively weak and are easily destroyed either by direct hits or by debris from the damaged structures, larger pigs are able to sustain more damage. Also, some pigs wear helmets as armor, making them more resistant to damage, while pigs with crowns can take the most damage.
Each level starts with the number, types, and order of birds pre-determined. If all of the pigs are defeated by the time the last bird is used, the level is 買粉絲pleted and the next level is unlocked.Points are s買粉絲red for each pig defeated as well as for damage to, or destruction of, structures, and bonus points are awarded for any unused birds. Upon 買粉絲pleting each level, players receive one, two, or three stars, depending on the s買粉絲re received. Players may re-attempt unlocked levels as many times as they wish in order to successfully 買粉絲plete them or to earn additional points and/or stars.
In early 2009, Rovio staff began reviewing proposals for potential games. One such proposal came from senior game designer Jaakko Iisalo[11] 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.As the 買粉絲ncept of Angry Birds was developed, 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.The game's mechanics were inspired by other petrary physics games that have been released over the years, including another 2009 release, Crush the Castle.The initial 買粉絲st to develop Angry Birds was estimated to exceed 100,000 Euros, not including money spent on the subsequent updates.For the Apple iOS version, Rovio partnered with distributor Chillingo to publish the game to the Apple App Store. Since then, however, Rovio has self-published almost all of the later ports of the game, with the
