Angry Birds (also known as Angry Birds Classic or AB Classic) is a puzzle slingshot game released in December 2009 on iOS and Maemo, later being released on Android in October 2010. The game was developed and published by Rovio Entertainment Corporation with the help of Clickgamer, and later Chillingo. Their fifty-second, Angry Birds was supposed to be Rovio's last game, but the game's success not only saved the company from bankruptcy, but started the entire Angry Birds media franchise.
In the game, the player launches the Angry Birds from a slingshot at pig fortresses containing the Bad Piggies who stole their eggs. Seven flock members debut in this game (Red, The Blues, Chuck, Bomb, Matilda, Hal and Terence), while two others (Bubbles and Stella) migrated from the indirect sequel, Angry Birds Seasons. Six types of pigs also appear, including three sizes of Minion Pigs, along with the Corporal, Foreman and King Pigs. There are over 700 levels in the game, spanning over 17 episodes, along with the Golden Eggs scattered across the game that the player can find.

One proposal made by Jaakko Iisalo in a simulated screenshot, where round birds were launching themselves into squares, drew attention to them by wondering what was happening in such image and approved it. The developers then started to further develop it. 
As the picture gave no clue of what was being played, they started to wonder how the gameplay could be. As cannon games were famous back in the day, the developers used a similar concept.
They also noticed the birds had no enemy. Jaako Iisalo liked to draw animal characters and pigs were something natural that came in his sketches. He never saw them as malicious, for him, the birds are the aggressive side while the pigs are just mischievous. The Swine Flu outbreak had a bit of influence when designing them, but wasn't a direct influence.
The game initially had some Role Playing elements where the player could modify the flock of birds .
The estimated initial price to develop Angry Birds was to exceed €100,000 ($113,869.30). 
Angry Birds was made by a team of four people and took at least eight months to finish.
Rovio partnered with distributor Chillingo to publish the game to the App Store. Chillingo has claimed to have participated in the game's development, as they were said to be responsible for adding trajectory lines, pig grunts, zoom option and birds' athletic jumps before going to the slingshot and waiting.
Since then, Rovio has self-published almost all of the later ports of the game, except for the PSP version, which was produced under license by Abstraction Games.
In December 11th, 2009, the game was released for IOS and Nokia devices. The game was initially paid and didn't sell many copies.
After Angry Birds was made a featured app in February 2010 on the United Kingdom, it reached the 1st position in a small period of time, and then reached the 1st position on the paid apps chart in the United States App Store in the middle of 2010 and stayed there for 275 days. 
In April 1, 2010, Angry Birds HD was released, featuring a retina display and HD graphics.
Knowing this, the developers started to develop an Android version of the game. They observed that Android had much different configurations; The combinations numbers of software versions, processing speed, even the user interfaces were significantly larger than the iOS version. The team then settled on a minimum set of requirements, even though that left nearly 30 types of Android phones unable to run the game, including some newly released devices.
In October 15th, 2010, the game was launched for Android devices, and the developers then started porting the games to other devices. The game's beta for Android hit more than one million downloads in three weeks
In April 2019, the game was unlisted in the app stores but came back and received a new update. Afterwards, it was then unlisted again in July 2019. Rovio Entertainment Corporation stated that they had removed the games for testing purposes, but never explained what the test was. Later, the statement was changed to say that the game was removed because Rovio did not want to keep updating the game.
In June 2021, it was announced by Rovio on Twitter that efforts were going to be made to bring some of the original Angry Birds games back to online stores sometime in the future.

- For information about each episode's plot, see the Episodes section.
The game takes place in the isolated Piggy Island. A flock of rare multi-colored birds, led by Red and containing the Blues (Jay, Jake and Jim), Chuck, Bomb and Matilda, guarded a nest containing three eggs. However, from the distance watched the Bad Piggies, led by the greedy King Pig Smooth Cheeks. These pigs have been relegated to eat grass, and King Pig, who, unlike his ancestors, has never eaten eggs and needs to keep that fact a secret, has had enough. Meanwhile, Red witnessed a mosquito touch one of the eggs. Furious, Red tried to fight the mosquito, but it got away (though in the cinematic trailer, he managed to defeat it). King Pig saw his chance, and, along with other high-ranking pigs Corporal Pig and Foreman Pig, stole the eggs while Red wasn't looking. Red and his comrades spotted the empty nest, and screamed in shock. Red, along with Bomb and Matilda, mourned the loss of the eggs, while the Blues spotted footprints leading to the pigs, whom Chuck had spotted. Using a slingshot, the birds slung themselves towards structures made by Foreman Pig, and managed to defeat all three elites and get their eggs back.
Afterward, the multiple episodes show the pigs trying new ways to get the eggs. The birds meet more members of their species along the way (Hal and Terence), and the battle continues to places such as a forest, a desert, a mine, a beach, a laboratory, and more. After the birds take out King Pig in a laboratory, his comrade, Foreman Pig, starts to get more control over the plans. He steals the eggs while the birds are visiting a farm, and after the birds defeat him there, he enters a time machine and goes back to the Triassic period of the world. The birds destroy many structures based on prehistoric animals before the pigs are defeated for what was seemingly the last time. The birds celebrate their victory while the pigs ride dinosaurs.
In Angry Birds, to play the game, the player needs to press the Episodes button, that will show the episodes. The player starts with the Poached Eggs episode.

In order to beat the level, the player has to defeat all of the pigs in the level. In order to defeat pigs, the player needs to hit them with birds, which can be done by using the slingshot.
The player can sling a bird by pressing the slingshot and holding while dragging the rubber. The longer the rubber is dragged, the farther the bird will fly. The rubber can be dragged to all sides, except in the middle. Leaving the bird in the middle will cancel the launch.
After a bird is launched, it will fly until its momentum ends. While the bird is in the air, it can activate its own ability. The birds are the following:
