The browser era of a mobile phenomenon, why almost every page offering it still exists, and where the builds are actually preserved.
For roughly a decade Angry Birds was genuinely playable free in a browser, first through an official Chrome release and then through a very large number of Flash implementations on game portals. That layer went offline in a single step at the end of 2020 when Flash support ended, and the pages advertising it mostly stayed up.
This entry separates the sources that are current from the preservation projects that hold what remains, with a note on how to tell a live page from a stale one.
Angry Birds arrived on iOS in December 2009 and became one of the defining mobile titles of the following decade. What made "free online" a meaningful search rather than a contradiction was the browser version: a Chrome release in 2011 brought a playable build to the desktop web, and a long tail of Flash implementations, some official and a great many not, spread across game portals for years afterwards.
That whole layer stopped working at once. Adobe ended support for Flash Player on 31 December 2020 and browsers removed the runtime entirely, which took every Flash implementation offline in a single step regardless of who had published it. The Chrome-era build depended on browser technologies that were also superseded. The result is that the great majority of pages still offering the game free online are offering something that no longer runs.
This is unusually clean as an example of a dependency taking content with it. Nothing was deleted for editorial reasons. A runtime was withdrawn, and a decade of pages that were correct when published became dead without anyone touching them.
The publisher and the reference record. Start here for what exists officially, because the aggregator pages in this space are almost entirely stale.
The developer and publisher. The current catalogue here is the authoritative answer to which titles are still supported and on which platforms, which is worth checking first because the series has been repeatedly relaunched, delisted and re-released under similar names.

The encyclopaedia article, covering the original release, the browser versions, and the series that followed. The most reliable route through the naming, which is genuinely confusing: several distinct games share nearly identical titles across a fifteen-year span.

Where the browser-era builds are preserved. Both of these are preservation projects rather than places to play casually, and both are explicit about what they hold.
The Internet Archive runs Flash content in an in-browser emulator, which is the main reason any of this era is still playable at all. Coverage is uneven and depends on what was collected before the runtime was withdrawn, so absence here is not evidence a build never existed.

A dedicated preservation project for browser games, holding a very large collection of Flash and other plugin-era content with its original assets. The catalogue is searchable and documents provenance, which matters in a space where unauthorised reuploads outnumber originals.

Adobe's own end-of-life notice, which is the single event that explains why almost every page promising this game free online no longer works. Worth reading once, because it dates the break precisely rather than approximately.

Search results in this space are dominated by pages that were accurate years ago. Three checks separate them quickly. Look for a Flash dependency, stated or implied by the page's age, because anything relying on it stopped working at the end of 2020. Check whether the page names a specific title in the series or only the series, since the vaguer ones are usually aggregator pages built for search traffic rather than for play. And check the publisher's current catalogue before believing any third party about availability.
The wider pattern recurs across this whole catalog and deserves naming. A page can become wrong without being edited. Content that depended on a runtime, an interface or a data service inherits that dependency's lifetime, and when the dependency goes the page stays up and stops being true.
The report on closed measurement tools documents the same failure in a different domain, where nine services that supplied website figures all closed and left a decade of citations pointing at nothing.
Not in the way the phrase used to mean. The Flash implementations that made up most of that layer stopped working when Adobe ended Flash support on 31 December 2020 and browsers removed the runtime. What remains is preservation: emulated builds inside archive projects, which run in a browser but are collections rather than live services.
Because the pages were never taken down. They were correct when published, they attracted search traffic, and nothing about the withdrawal of a browser plugin causes a page to be edited. The result is a large stale layer that looks live and is not, which is a general property of dependency-driven content rather than anything specific to this game.
The series spans well over a decade, with sequels, spin-offs, seasonal editions and relaunched versions under near-identical names, plus delistings and re-releases. The encyclopaedia article is the most reliable way through it; the publisher's current catalogue is the authority on what is supported right now.
The preservation projects named here document provenance and operate as archives with stated collection policies, which is a different thing from a portal hosting an unauthorised copy for advertising revenue. When using material from this era, the distinction is worth checking, because unauthorised reuploads considerably outnumber preserved originals.
