Angry Birds (game)

If you are looking for the series, see Angry Birds (series).Angry Birds (later remarketed as Angry Birds Classic) is a casual puzzle video game developed by the Finnish computer game developer Rovio Entertainment that started the Angry Birds franchise. Inspired by sketches of stylized wingless birds done by Jaakko Iisalo, the Swine flu epidemic and games like Crush the Castle, the game was first released for iOS and Maemo in December 2009. Since that time, over 12 million copies of the game have been purchased from the iOS App Store, which has prompted the company to design versions for other touchscreen-based smartphones, most notably those using the Android, Symbian, Windows Phone, and BlackBerry 10 operating systems. The series has since expanded to include titles for dedicated video game consoles and for PCs. This game introduced the original five, Red, The Blues, Chuck, Bomb and Matilda, later introducing Terence and Hal into the series. New additions from Angry Birds Seasons (Bubbles and Stella) were later added.

In the game, players use a slingshot to launch the birds at pigs stationed in or around various structures with the goal of killing all of the pigs on the playing field on each level in order to get 3 three stars. As players advance through the game new types of birds become available, some with special abilities that can be activated by the player. Rovio Entertainment has supported Angry Birds with numerous free updates that add additional game content, and the company has also released stand-alone holiday and promotional versions of the game.

Angry Birds has been praised for its success for leveraging a combination of addictive gameplay, comical style, and being free into a viable franchise with long-term potential for profit. The game's popularity has led to the production of additional versions of Angry Birds for personal computers and gaming consoles, as well as a market for merchandise featuring its characters and even spawning a feature film, a television series, multiple spin-offs, including one revolving on the game's antagonists and even more. With a combined tally of over 4.4 billion downloads across all platforms as of March 2019, including both regular and special editions of the software, 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".

It also has 9.2 million daily active users and 66.8 million monthly active users.

In October 2019, this game, along with many other old Angry Birds games, has been removed from the App Store. Rovio has said they removed the games for testing, but if that was the truth they would’ve been back on the App Store by now.

History
More info is available on Angry Birds (series).

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 didn't 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 ($113,869.30), 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, except for the PSP version, which was produced under license by Abstraction Games.

When Rovio began writing new versions of the game for other devices, new issues came to light. As the team began working on a version for Android systems, they observed a large number of configurations of device types and versions of the Android software. The number of combinations of software versions, processor speed, and even user interfaces was significantly larger than that for the iOS version. Ultimately, the team 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 phones. It was released on October 15, 2010. One month after the initial release on Android, Rovio Entertainment began designing a lite version of the game for these other devices.

In early 2010, Rovio began developing a version of Angry Birds for Facebook. The project became one of the company's largest, with development taking over a year. The company understood the challenges of transplanting a game concept between social platforms and mobile/gaming systems. In a March 2011 interview, Rovio's Peter Vesterbacka said, "you can’t take an experience that works in one environment and one ecosystem and force-feed it onto another. It's like Zynga. They can’t just take FarmVille and throw it on mobile and see what sticks. The titles that have been successful for them on mobile are the ones they’ve built from the ground up for the platform." The Facebook version incorporates social-gaming concepts and in-game purchases and entered beta-testing in April 2011; the game became officially available on Facebook in February 2012.

Improvements for the game include the ability to synchronize the player's progress across multiple devices; for example, a player who completes a level on an Android phone can log into their copy of the game on an Android tablet and see the same statistics and level of progress.

Prologue
The plot of the game takes place on Piggy Island. The Flock happily lives together taking care of their Eggs.

Poached Eggs
Suddenly, King Pig and his minions steal the eggs. They attempt to cook and eat eggs. The birds injure Corporal Pig, Foreman Pig, and finally King Pig.

Mighty Hoax
In the second part of the plot, King Pig once again stole the eggs, but rather than simply fleeing, he placed cardboard cutout eggs in the birds' nest. The birds weren't fooled by this trick, and once again released their vengeance on the pigs for stealing the eggs the second time. There was also a cardboard cutout King Pig used to distract the birds. however, King Pig was behind it. In the end, the birds didn't defeat him. Instead, they just destroyed the cardboard cutouts.

Danger Above
The birds finally found out about the trick and the real King escaped to the jungle, a city, and the clouds. It turned out they flew out with balloons, stealing the eggs. The birds freed Hal, along their journey, befriended him, then he joined their flock. They get the eggs back.

The Big Setup
Next, King Pig and his minions kidnapped the entire flock to prevent the birds from defeating them and stole the eggs. Terence noticed this and decided to exact revenge on the pigs for kidnapping the other birds. In the meantime, the pigs attempted to reconstruct their forts. Quite anxious, Terence went to destroy the fortresses. He then sees Hal kidnapped again and frees him. Together, they freed the Flock. In the end, Terence and Hal put King Pig in a cage. Terence was given membership into the flock.

Ham 'Em High
King Pig was freed by his friends. He, the Foreman Pig, and a Small Pig use a lasso to drag the eggs from the nest to them, trying not to get too close. This brings both the Birds and the Pigs to the Wild West, where the pigs are wearing cowboy hats and fedoras. The King Pig, on the other hand, is wearing a big sombrero. In the end, the birds rip King Pig's sombrero over his head.

Mine and Dine
Next, King Pig and the other pigs try digging underground. The pigs, wearing mining hats and carrying pickaxes, dig a hole near the birds' nest and swipe the eggs from there. They escape through a giant cave, but the birds quickly follow. In the end, the birds shoved King Pig into his mining helmet.

Birdday Party
After this, The Birds notice that their eggs are gone and pieces of cake are too. Bubbles is worried. The Pigs stole the eggs, along with the missing pieces of cake and a candle. They are covered in frosting. The Birds do not defeat King Pig in the last level because he was not there; however, King Pig was defeated by the birds in the end, covered in frosting. In the new update for this episode, the Moustache Pig takes the King's place when level 18-15 is beaten. He is then defeated in level 19-15.

Bad Piggies
Next, King Pig teams up with Ross and the Mechanic Pig to get the eggs. He is defeated in the end. Strangely, Ross survived unharmed.

Red's Mighty Feathers
Then, The Angry Birds and Bad Piggies are fighting over the Eggs again, but Red is frustrated over a lack of a special ability. Just then, the Mighty Eagle flies by and gives Red a new power. Red joins his fellow birds in their crusade to rescue the eggs.

Short Fuse
The story then turns over to Bomb, where he receives a new power. The Pigs (wearing lab coats) stole the Eggs again and brought them to Professor Pig's laboratory, little do they know that a leaking pipe gave Bomb a new power.

Surf and Turf
Then, King Pig orders his minion pigs to steal the eggs with balloons on the beach, while he and the Foreman Pig watch. In the end, the Birds defeat King Pig yet again.

Flock Favorites and Birdday 5
The flock celebrates their birthday, while still fighting the pigs.

Bird Island
The flock returns to their original home, Bird Island, where they fight the pigs again.

Surf and Turf
King Pig orders his minion pigs to steal the eggs with balloons on the beach, while he and the Foreman Pig watch. In the end, the Birds defeat King Pig yet again.

Piggy Farm
The birds continue their fight on a farm, while the pigs get defeated again.

Jurassic Pork
The birds travel back in time to the time of their ancestors, the dinosaurs, while still fighting for the eggs. The pigs, of course, get defeated, for once and for now.

Golden Eggs
The birds examine multiple gold eggs they've recovered in their journeys defending the eggs. The pigs then try to steal it while the birds defeat them again.

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. The game remembers the trajectory of the previous Bird launched, allowing the player to use it to make any needed adjustments to their next shot. 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.

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, green bird boomerangs back 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 can withstand more damage before succumbing to defeat. Besides, 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 killed, the level is incomplete and must be repeated. Points are scored for each pig killed 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 may re-attempt unlocked levels as many times as they wish to complete them successfully or to earn additional points to get more stars.

Power Ups
You may also use Power-Ups in levels of the game. Power-Ups can help you improve your scores in levels and help you get more stars. There are 4 Power-Ups, and you can use 2 per level. Here are the 5 Power-Ups


 * Power Potion / Super Seeds: They can turn any bird on the slingshot bigger.
 * King Sling: Upgrades your slingshot so that when flung, birds can go faster and farther than before.
 * Sling Scope: Allows you to see where your bird is going to crash/land go before you fling them, you can activate this Power-Up for 5 minutes on the shop.
 * Birdquake: Rumbles the ground in a level and can make pig's structures fall.
 * Shockwave: Bomb with the Shockwave ability to demolish the blockers and pigs.
 * Red’s Mighty Feathers: iOS exclusive, Gives a Red bird that can fly into a targeted area, buy and use it at any level. Only available for purchase during the (RED) update.
 * TNT Shield: Used on the Mighty League, it prevents you to go back to a lower league if you couldn't enter a high leaderboard on the daily levels.

Power-Ups are limited, and if you run out, you must purchase more to have more with these exceptions.


 * Slot Machine: In Angry Birds Classic, you can play any level daily to receive a free daily Power-Up from the "Angry Birds Power-Up Slot Machine". Whatever Power-Up you get three in a row in the Slot Machine, that'll be the Power-Up you'll receive. For example, get three Birdquakes in a row in the Slot Machine, you'll receive a Birdquake. Be aware that the Slot Machine goes only once every day, so once you received your free daily Power-Up, you will have to wait until the next day to receive another Power-Up from the Slot Machine. Unlike the Space Eagles from Angry Birds Space, which are received normally after the hour you received one when the next day comes if you start any level, the Slot Machine appears anytime.
 * Watching an Ad: It's a free way to earn a Power-Up by watching an ad, it gives you only 1 determined Power-Up and it's automatically used in the level.

Characters
There are currently nine different styles of playable birds (ten if you count the Mighty Eagle). They are shown in the order they are first presented to the player.

Each bird has a different ability, such as being able to boomerang back, splitting into three, or exploding. These abilities are activated by tapping or clicking the screen while the bird is flying. Below is the list of birds along with their real names.

Reception and Critical Acclaim
Reviews for Angry Birds have been mostly 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 wrote that "going for the maximum number of stars certainly adds a lot of replay value to a fairly extensive game".

Reviews for the first versions of the game that did not use a touch-screen, the PlayStation 3/PSP version, and the Windows version, have also been positive, but with some disagreement over the different interfaces. Will Greenwald of PC Magazine, in his review of the PlayStation Network version, said that the control scheme on these platforms is good, "but they're not nearly as satisfying as the touch-screen controls found on smartphone versions", and that the PlayStation 3 version appeared "blocky and unpleasant, like a smartphone screen blown up to HDTV size". Conversely, Greg Miller of IGN preferred the analog control setup of the PSP version, saying it "offered me tiny variances in control that I don't feel like I get with my fat finger on a screen". While giving the game a positive review, Miller concluded, "There's no denying that Angry Birds is fun, but it could use polish – such as sharper visuals, a better price, and smoother action." Damien McFerrin of British website Electric Pig reviewed the PC version, saying "the mouse-driven control method showcases many distinct advantages over its finger-focused counterpart".

Angry Birds has also been described critically as impossible to understand the playing rules criteria by game critic Chris Schiller of Eurogamer.net, which has 'a contemptuous attitude towards its players, keeping them just frustrated enough not to switch off and play something else instead.'

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 a few weeks later, where it remained until October 2010. Since release, the free, limited version of Angry Birds has been downloaded more than 11 million times for Apple's iOS, and the full-featured paid version has been downloaded nearly 7 million times as of September 2010. The Android version of the game was downloaded more than 1 million times within the first 24 hours of release, even though the site crashed at one point due to the load, and over 2 million downloads in its first weekend. Rovio receives approximately US$1 million per month in revenue from the advertising that appears in the free Android version.

According to Rovio, players log more than 5 million hours of game time each day across all platforms, along with 200 million monthly active users. In November 2010, Digital Trends stated that "with 36 million downloads, Angry Birds is one of the most mainstream games out right now". MSNBC's video game news blog has written that "[n]o other game app comes close" to have such a following. The Christian Science Monitor has remarked, "Angry Birds has been one of the great runaway hits of 2010". In December 2010, in honor of the first anniversary of the release of Angry Birds, Rovio Entertainment announced that the game had been downloaded 50 million times, with more than 12 million on iOS devices and 10 million on Android. By January 2014, the game had reached 2 billion downloads, including Angry Birds, Angry Birds Seasons, Angry Birds Rio, Angry Birds Space, Angry Birds Star Wars & II and Angry Birds Go!. On Christmas Day 2011 alone, 6.5 million copies of the various Angry Birds games were downloaded across all supported platforms.

In the history of the Apple App Store, Angry Birds holds the record for most days at the top of the Paid Apps chart, having spent a total of 275 days at the No.1 position; Angry Birds Rio has been No.1 for a total of 23 days, ranking ninth on the list. In Apple's "iTunes Rewind" list of the most popular iTunes Store media for 2011, Angry Birds was the top-selling paid iPhone/iPod app on the App Store and its free version was fourth-most downloaded. The game's two special-edition versions, Angry Birds Seasons and Angry Birds Rio, were also ranked in the top 10 for paid iPhone/iPod apps, while its iPad-exclusive Angry Birds HD versions were the top-selling and top-downloaded iPad apps for the year. Mattel also made a few board games based on the app. These were called Angry Birds: Knock on Wood, Angry Birds: On Thin Ice and Angry Birds: Mega Smash.

Awards
In February 2010, Angry Birds was a nominee for the "Best Casual Game" award at the 6th annual International Mobile Gaming Awards in Barcelona, Spain. In September 2010, IGN named Angry Birds as the fourth best iPhone game of all time. In April 2011, Angry Birds won both the "Best Game App" and "App of the Year" at the UK Appy Awards. At the 2011 Webby Awards, Angry Birds was awarded "Best Game for Handheld Devices".

Angry Birds Classic for Kakao
Angry Birds Classic for Kakao is the Korean version of Angry Birds Classic. The game was released on February 16, 2015. It is only available on Google Play for the Korean marketplace.

The gameplay is still the same as the original version, but the only difference in the Kakao version is it has a life system and an adventure map-like level select, like Angry Birds 2.

However, the ratings of Korean users are the lowest among the Angry Birds series games.

Unused Content
'Main Article: Angry Birds (Classic)/Unused Content'

StellaLevel
There is an unused level in the game called StellaLevel (sic). The level refuses to load. It is thought to be a level where you only use Stella, who was not included in the game back then.

Bubbles
Bubbles, unlike Stella, is actually able to load. However, the level is always messed up and will give you a score of zero. The slingshot is stuck in the ground, so it is impossible to fling a bird. To add fuel to the fire, there are also no birds included in the level.

Design Update
There is an unused poster of a new update. It is a file with a poster that has a texture of buttons and a wood background but is not playable. They are:
 * 1) 2 Chuck's (new game design)
 * 2) 1 Bubbles
 * 3) 2 Minion Pigs (new game design)
 * 4) The background for Red's Mighty Feathers levels.

All of the characters use their Toons Designs. The sprites are very similar to Angry Birds Friends!'s new Toons sprites.

This poster appeared when the player paused the game, it was promoting the game.
