Angry Birds was created by Finnish game developers in 2009. By 2015, 3 million people downloaded the game. Due to the popularity, many other versions of the game were created for PCs and various gaming consoles. Angry Birds Online, Angry Birds Rio, and Angry Birds Bad Piggies are different versions of the game that were added due to popularity. In 2015, Angry Birds became part of a theme park and a movie was released in 2016. The full version of the app costs $0.99 in the app store as well as the option to download a free version with advertisements.
During gameplay, the player place their finger (on the touchscreen) within the slingshot, causing the next bird in the queue to be instantiated. As the player pulls their finger down and to the left, the bird follows and pulls the slingshot's sling taut. When the player releases their finger, the selected bird is fired to the right across the level, with the goal being the destruction of all green pig enemies. The goal must be completed using only the number of birds provided. Bonus points are awarded for completion of a level with extra bird ammunition remaining. Pigs may be protected by wood, concrete, ice, stone, or other materials in addition to the natural terrain. Using the bird projectiles, the player can hit the pigs directly or through chain reactions using unstable structures and explosive objects. Additional elements are introduced as the game progresses that aid the player in eliminating pigs, such as rocks and explosives. As the player advances through the different levels, players are introduced to different "angry birds", each with different features.
Type of Birds
|Color of Bird||Description|
|Red||This is the only bird used in the earliest levels of the game. As the player advances, additional types of birds become available.|
|Blue||When the screen is tapped, turn into three, small, fast flying birds.|
|Black||When screen is tapped, explodes like a bomb.|
|White||When screen is tapped, drops explosive eggs.|
|Yellow||When screen is tapped, speeds up.|
The size of the pigs varies from level to level. Small pigs are weaker and large pigs are tougher to destroy. Some pigs wear helmets that act as armor, increasing their difficulty to destroy.
Each level has a predetermined bird and pig count. When all of the pigs have been killed, with or without use of all the birds, the player advances to the next level. Points are awarded based on each pig destroyed, damage to each pig and structure, and unused birds. At the end of each level, stars are awarded depending on the score received. The maximum amount of stars for each level is three stars. Levels may be played more than once.
Angry Bird characters have been featured in many advertisements for other products. Characters began appearing in advertisements for Microsoft's Bing search engine. Airlines have also decorated their aircraft with angry birds.

In attempts to expand the Angry Birds brand name, the official website offers plush birds and pigs, T-shirts, iPad cases, Christmas stockings, backpacks, and key chains. Over 10 million Angry Birds toys have been sold thus far.
In May 2011, Mattel released an Angry Birds board game, entitled "Angry Birds: Knock on Wood".
Angry Birds has even received publicity from piracy. Angry Birds’ Chief Executive Mikael Hed didn't denounce piracy and claimed that it could increase business.. Many people are able to "jailbreak" iOS and Android mobile device to download paid versions of the game for free. The extra downloads increase the game's popularity and consequently spurs more interest around the world. Mikael Hed also noted that unlicensed merchandise sold in Asia can actually draw more fans and contribute to the worldwide popularity of Angry Birds.
In September 2011, the Window of the World theme park in Changsha, China opened an unlicensed Angry Birds attraction. Visitors to the park use a large slingshot to launch stuffed versions of the bird characters at green balloons representing the pigs. Upon learning of the attraction, Rovio Mobile was reported to consider working with the theme park to officially license the idea.
On December 11, 2012, the third anniversary of Angry Birds, Rovio announced that plans for producing and financing a full-length feature film surrounding the characters and other properties of the game. John Cohen, producer of the hit animated movie of 2010, "Despicable Me", was a producer of the movie. This was Rovio's first venture into the film industry as the Angry Birds brand was expanded into other sources of entertainment besides just mobile devices. The finished film was released on May 20, 2016, starring Jason Sudeikis and Josh Gad. The film received mixed reviews. Some praised the film's moral, saying that "Agreeability gets you so far in life, but when the chips are down, it helps to lose your temper sometimes." Whereas critics say, "There's a little bit of a moral about being inclusive, but that's not why this movie was made: It's about angry outbursts, birds catapulting through the air, and big explosions."

Other Related Games
On September 27, 2012, the creators of Angry Birds released Bad Piggies.. This game mimics Angry Birds but is from the perspective of the pig characters in the Angry Birds games. The game gives the pigs, who were the victims in Angry Birds, a chance to "fight back" against the Angry Birds. Instead of the original Angry Birds, where the birds are launched at the pigs, this game is based around creating flying machines to create a safe destination for the pigs. Levels allow the user to create contraptions using a variety of different elements and tools in order to transfer the piggies to safety. The game has over 100 million downloads and has a 4-star rating on the App Store and a 4.5-star rating on the Android Store.
There are concerns about Angry Bird's use of of violence. The slingshots used to kill the pig characters sparked controversy as well as claims arguing that Angry Birds promotes animal cruelty. Commonsense Media, a website for parents to evaluate video games for their children, declares Angry Birds as appropriate for those eight years old and older, giving it a rating of 2/5 for violence.  This differs from the Apple Store advertising the application as appropriate for ages 4+. In 2012 UK Labour MP Keith Vaz petitioned the House of Commons in efforts to make stricter guidelines and warnings for video games. In his case, he likened Angry Birds to other target-based shooting games including first-person shooters. He received criticism from The Guardian contributor Martin Robbins for equating the levels of violence between the two categories of games.
Battery Life for Advertisements
The Verge reported Angry Birds as an instance of a resource-heavy application, with claims that it consumes nearly twice as much battery than necessary. Most of the drainage is occurs in the free version of the game, utilizing 70% of the application's resource usage to access and upload information as well as download advertisements. The premium version is $0.99 and does not include these features and battery concerns.
Other apps on the Android Market face the same battery consumption issues between premium and free versions. Angry Birds is more commonly known for this problem due to its widespread popularity. 
Video Game Addiction
Angry Birds has been linked to video game addiction. The fifth and most recent version of the [| Diagnostic and Statistical Manual of Mental Disorders] names "Internet Gaming Addiction" as a condition that should be studied more and potentially added to the next edition . On-line Gamers Anonymous is a community for those who have experienced side effects from "excessive game playing" and was formed in 2002 by a mother whose son committed suicide from what they speculated to be a video game addiction . In 2017, Dr. William Klemm wrote in Psychology Today that video game addiction is noted by a changes in mood and behavior. . reSTART is another video game addiction support network that hosts therapy and retreats to promote healthy use of digital media..
The initial simplicity of the game encourages players to move up through levels and invest more time into the game as there are many levels that are relatively short, which allow the players to improve their skills. The game incorporates a difficulty curve which increases expected playtime per level as the game progresses. Despite the increase in difficulty with proceeding levels, the general simplicity of the game allows players to have a difficult time separating themselves from the screen.
Angry Birds also encourages players to replay previously completed levels. More skillful completions of a level award players with more stars and points, which creates player competition to achieve higher scores. These mechanics have been shown to raise endorphin levels, increasing the risk of addiction.
While some Angry Birds require an upfront purchase of the content, most games are free to download and later include in-app purchases. Users often enter the gaming environment expecting to have all of the content in the game available to them as they advance in their play. When a user reaches a point in the game where a purchase will advance their game-play significantly, users agree to pay a small dollar amount and might continue doing so. The price of freemium models like Angry Birds can result in significant cost to the user. The App store on iOS devices has attempted to remedy these concerns by displaying whether an application offers in-app purchases at the time of download.
Concerns about in-app purchases have increased with the introduction of new versions of the game. Angry Birds 2 was met with criticism for its style of gameplay which has been said to encourage in-app purchases.  Users are given five attempts within a certain amount of time to beat a level. If the user fails within those five attempts, they must either wait until their lives are replenished after a certain amount of time or they can redeem gems for more lives. These spending incentives influence users to buy in-app purchases and raise concerns for younger users. In-app purchases on Angry Birds can convince younger users to pay for in-app accessories to enhance their gaming experience or allow them to continue playing the game when their lives run out, capitalizing on the lack of awareness from a younger user. Although users are able to collect gems through completing challenges within the game, they can also purchase them with cash in the game's store.
Angry Birds tracks the location of players and collects their data to make personalized advertisements. Advertisers use user data because privacy laws are evolving at a slower rate than technological innovations, creating vulnerabilities in the system. This raises concerns among users that have downloaded the game but do not want the application to utilize their personal information. Leveraging consumer data can cause ethical concerns when a device is personalized with target ads. If the device changes to a new person, such as in a workplace, the advertisements shown may reveal private information about the previous user. Applications often do not share privacy policies with the user, and if they do, the user cannot use the application unless they agree to the terms. Free apps face greater ethical scrutiny because their revenue comes from advertisers as well as developers who sell personal data.
The Children's Online Privacy Protection Act (COPPA) prohibits advertisers from collecting personally identifiable information from anyone under the age of 13. There have been many allegations about advertisers going around this law to collect information in order to advertise to them. Many advertisers are able to find easy loopholes to target children and it becomes the responsibility of the parent to monitor where their child is leaking information. Companies are able to collect data on their users, whose age is often not apparent. They can then categorize users as children based on their actions and target relevant advertisements at them. There are many applications specifically built to help protect these consequential scenarios. For example, apps such as "App Lock" and "Net Nanny" can refrain children from using an app without parental permission. Requiring a passcode on the iPhone is also another example of this.
