Angry Birds (game)

Angry Birds is an application for the iOS, webOS, Android and Maemo mobile operating systems. It was released by Rovio Mobile and made in Helsinki, Finland. The objective of the game is to eliminate pigs and destroy their buildings and structures at the same time. This is done by the birds launching themselves out of a giant slingshot and hitting the pigs' various constructs, henceforth eliminating them. Each level allots the player a certain number of birds, which must be used in the order provided.

Birds
There are currently seven different styles of birds, shown in the order they are first presented to the player. Each bird has a different ability, such as being able to boomerang back on itself, or exploding, these abilities are activated by tapping the screen while the bird is flying.
 * Red Bird
 * Blue Bird
 * Yellow Bird
 * Black Bird
 * White Bird
 * Boomerang Bird
 * Big Brother Bird

These is also the Mighty Eagle, which can be summoned to automatically complete any level, but can only be used once an hour on non-completed levels.

Pigs
The bird's nemesis are a colossal group of pigs, and much like the birds, the pigs are also provided in different varieties, shown below:
 * Small Pig
 * Medium Pig
 * Large Pig
 * Armor Pig
 * Mustache Pig
 * King Pig

 * 1) Trick or Treat, the Halloween-themed episode, shows the pigs scaring the birds, distracting them from the eggs, which allow the pigs an easy opportunity to swipe them. Contains 45 levels.
 * 2) Season's Greedings, the holiday-themed episode. It does not show an episode introduction cutscene, although the basic plot remains the same. Has the form of an advent calendar that releases one new level each day from December 1st to 25th.

There are also Golden Eggs scattered throughout the game, which unlock hidden levels when collected.

Reception
The reviews of Angry Birds have been generally very positive. Chris Holt of Macworld called the game "an addictive, clever, and challenging puzzler", and Pocket Gamer's Keith Andrew said Angry Birds is "a nugget of puzzling purity dished out with relish aplenty." Jonathan Liu of Wired News noted that "going for the maximum number of stars certainly adds a lot of replay value to a fairly extensive game." The game was nominated for the "Best Casual Game" award at the 6th annual International Mobile Gaming Awards, announced in Barcelona, Spain in February 2010.

Angry Birds became the top-selling paid application on Apple's UK App Store in February 2010, and reached the top spot on the US App Store in the spring of 2010.
