Full Article: List of Angry Birds levels

In all versions of Angry Birds combined, there are a grand total of 364 levels in Angry Birds, 258 in the original game, and 106 in Angry Birds Seasons. These levels are grouped into "episodes", which consist of one to three worlds each.

Aim of the Game
The aim of the game is to fire the bird in the slingshot to towards the Pigs who apparently stole their eggs. Move the slingshot backwards to make the bird fly forwards to the pig. Make sure you aim it correctly. If you also touch the bird again while it is moving, the bird will do a special trick, besides the Red Bird and the Big Brother Bird which just make weird noises.
 * 1) Poached Eggs - 63 levels, the pigs simply steal the eggs and attempt to escape. Contains 63 levels, which must be conquered before any of the other episodes may be played.
 * 2) Mighty Hoax - 42 levels, the pigs steal the eggs and distract the birds with a cardboard cut-out.
 * 3) Danger Above - 45 levels, the pigs steal the eggs and escape on board a number of makeshift aircraft.
 * 4) The Big Setup - 45 levels, the pigs imprison the birds in a cage to prevent their defeat after stealing the eggs. However, Big Brother Bird is still loose and fights back.
 * 5) Ham 'Em High - 48 levels, the pigs, armed with a lasso and cowboy gear, steal the eggs out of the bird's nest, and escape to the Wild West.
 * 6) Mine and Dine - '45 levels, the pigs steal the eggs and hide underground in an abandoned mine shaft where the birds must stop them.

Angry Birds Seasons

 * 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 Christmas-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.
 * 3) Hogs and Kisses, the Valentines' Day episode, once again does not show an intro, but it is explained that the pigs steal an egg with a bow on it, and the birds attempt to retrieve it so they can pair it with an egg wearing a baseball cap. Contains 18 levels.
 * 4) Go Green, Get Lucky, the St. Patrick's Day themed episode, once again lacks an introduction sequence, but it is stated that the pigs have once again taken the eggs.
 * 5) Easter Eggs, the Easter-themed episode, once again lacks a cutscene, but it is stated that the pigs replace the birds' eggs with Easter ones. Is the only episode in Angry Birds/Seasons with 11 Golden Eggs, the most of any episode to date.
 * 6) Summer Pignic, the Summer-themed episode, uses an advent calendar system very similar to Season's Greedings. It focuses on the Pigs attempting to have a picnic with the Bird's Eggs as the main course.

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

Trivia

 * On the main menu of the original game, when the player touches any of the flying birds, (not including the ones far off into the background), that bird will make its signature noise (The noise the bird makes when it is fired from the slingshot).
 * When they player gets 3 stars on every level in an episode, the corresponding item that flies around on the main menu will have stars on them. (Ex: when Mighty Hoax is completed, all flying cardboard King Pigs will have star glasses.
 * On the Cartoonnetwork show Mad, there is a spoof of Angry Birds called Angry Birds Management.
