Angry Birds (game)



 The Angry Birds'' theme

''If you are looking for the series, see Angry Birds (series).

Angry Birds (later remarketed as Angry Birds Classic) is a puzzle slingshot game, developed and published by Rovio Entertainment Corporation, with the help of ClickGamer and Chillingo.

Development
Undergoing a financial crisis, Rovio Entertainment Corporation got its workforce reduced from 50 to 12 employees, and the staff started looking for proposals to overcome this. One proposal made by Jaakko Iisalo in a simulated screenshot, where limbless birds were launching themselves into geometric shapes, 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, such as Crush the Castle, the developers used them as a model, and added the Slingshot mechanic into the game.

They also noticed the birds had no enemy. In 2009 the swine flu epidemic was popular in the news, such flu was known for affecting pigs and make green spots appear on them. Influenced by this, the developers chose green pigs as enemies for the birds.

The developers also once thought of making the game have a Role-playing mechanic where players could build their own team of birds, but this didn't get past concept. 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 eight months to finish because it was such a low priority for the company.

Rovio partnered with distributor Chillingo to publish the game to the App Store. Chillingo was claimed to have participated in the game's development, 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.

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, it 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

On August 2th 2012 Angry Birds HD got retina display and HD graphics.

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
After the birds went back to the ground, King Pig and his minions kidnapped (or birdnapped) 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
After a rootin' and tootin' adventure, 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
When the birds exit the mine, they 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
After a celebration, 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
When they continuing their journey, 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. This is the first episode to have Chrome designs.

Surf and Turf
Bomb's Shockwave power was good but 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.

Piggy Farm
The birds notice that the eggs were stolen by Foreman Pig and his cow pigs on a farm, they fight them while the pigs get defeated again, but Foreman Pig escapes and enters a Time Machine set to travel back to 65 Million Years.

Jurassic Pork
After entering Foreman Pig's Time Machine, the birds travel to the time of their ancestors, the dinosaurs, while still fighting for the eggs and facing various Prehistoric Animals and Fossil Monsters. The pigs, of course, get defeated, for once and for now.

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.

In the opinion of the general public, the best Angry Birds character to use is either Bomb for his power to blow things up, or Terence, because he could destroy structures.

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.
