On December 11, 2014, in honor of the Angry Birds' 5th birthday, an episode with 30 user-inspired levels was added.[63] On June 23, 2015, Flock Favorites was added with a second and final slate of 15 levels inspired by previous episodes.[64] On December 11, 2015, in honor of Angry Birds 6th birthday, new 15 levels were added to Birdday Party.[65] On November 10, 2016, 21 levels were released as singular episode called "Bird Island" that promoted the Angry Birds Movie, though the levels didn't unlock for players until November 17.[66][67]
On December 10, 2016, in honor of Angry Birds' seventh birthday 15 more levels were released as an addition to Birdday Party (though the levels didn't unlock until December 17).[68] In the following months, a newer episode called "Piggy Farm" would be released as a set of 15 levels on February 27, 2017, with two subsequent updates on March 30, 2017, and May 16, 2017, providing the next 15 levels and final 15 levels respectively.[66][69] On the May 16 update, a dual virtual currency system was also added to the game, in which currency is earned throughout gameplay (or accrued through in-app purchases) and can be used to purchase power-ups and other in-game items. The next subsequent update, which released the first 15 levels of the last chapter "Jurassic Pork" and served to conclude the unresolved plot in "Piggy Farm", arrived on August 23, 2017, followed by an update of 15 more "Jurassic Pork" levels on September 15, 2017.[70][71] The final levels of "Jurassic Pork" and the most recent levels of the game would release as a set of 16 levels on November 20, 2017.[72] In spite of the upcoming 8th anniversary of the game, no new 'Birdday Party' levels would be released and all subsequent updates until the game's 2019 removal would solely feature bug fixes.
Since its initial release for the Nokia N900 multimedia Internet device, and Apple's iPhone and iPod Touch mobile digital devices, Rovio has released versions of Angry Birds for additional devices. An iPad-exclusive version, Angry Birds HD, was released with the iPad mobile digital device in April 2010.[73] In August 2010, Angry Birds was made available to the Palm Pre phone running Palm's webOS operating system through its App Catalog online store.[74] Symbian^3 phones received a version of the game in October 2010,[75] which initially includes only the "Poached Eggs" and "Mighty Hoax" episodes.[76] Angry Birds works on Kindle Fire and Kindle Fire HD.
In May 2010, Rovio announced plans for a version for devices using Google's Android operating system,[77] with a beta version being released through the Android Market (now Google Play) in September 2010.[78] The full Android version of the game was first released instead on GetJar in October 2010,[79] though it was subsequently released on Android Market within days.[80] Rovio officials noted that GetJar had a more global reach than Android Market, and GetJar's availability on other smartphone platforms (including Symbian) would make cross-platform promotion of the game easier.[79] Unlike the previous versions, Angry Birds for Android is a free, ad-supported application, as paid applications aren't available on Android in some nations.[80] An update called "Bad Piggy Bank" enabled players to buy out the in-game ads.[81]
In October 2010, Microsoft suggested on one of its websites that a Windows Phone version of Angry Birds was in development. Rovio complained that Microsoft had not asked permission to make such a statement, noting that at that time it had not committed to design a Windows Phone version. Although Rovio asked Microsoft to revise its site to remove references to the game,[79][82] a Windows Phone version was ultimately released in June 2011.[83]
Near the end of 2010, Rovio stated that it was developing new ports of the game, this time for devices outside of the mobile phone market. In January 2011, three of those ports launched. First, Sony announced the release of Angry Birds for its PlayStation Portable handheld system in the form of a PlayStation mini game that includes nearly 200 levels from the original game; the version is also playable on the PlayStation 3.[84][85] Next, Rovio announced the release of a Windows version of the game[86] on January 4, 2011, available for sale exclusively from the Intel AppUp center, which included 195 levels at launch and plans for exclusive features not available on the smartphone versions.[87] One day after the Windows version was released, the Mac App Store launched, with one of the first offerings being its own version of Angry Birds.[88] Ports of Angry Birds have also been proposed for the Wii[6] and Nintendo DS systems,[89] with the former becoming realized through Angry Birds Trilogy (see below). A 3D-enhanced version of the game was proposed for release on the LG Optimus 3D in October 2011.[90][91]
The popularity of Angry Birds has helped spread the game to other devices that were not initially designed as gaming machines. Barnes & Noble announced that a future update for its Nook Color e-reader will let the Android-based device run applications, including a port of Angry Birds.[92] In June 2011, Rovio announced plans to partner with Roku to include a version of Angry Birds on a new model of its Internet-connected set-top box, the Roku 2 XS.[93]
In May 2011, an in-browser HTML5 version[94] of Angry Birds was released in beta form. The game uses WebGL or Canvas and is distributed through the Chrome Web Store for use with Google's Chrome web browser. It runs on any WebGL- or Canvas-enabled browser, and features exclusive content when played on Chrome, such as exclusive levels[95] and the so-called "Chrome Bombs". The version includes offline playability and features 60 FPS gameplay with a selection of graphics settings to accommodate a variety of hardware capabilities.[96]
