10 Oldest Browser Games Still Playable in 2026

Most “old” browser games died with Flash in 2020. Many more died when Java applets got pulled from mainstream browsers around 2017. But a stubborn minority survived — either because they were ported, because they used technology that didn’t need plugins, or because someone with too much spare time and a server keeps them running. Here are ten of the oldest browser games still playable in 2026, ordered by how early their original version dates back.

1. NetHack (1987) — playable in browser today

NetHack started life in 1987 as a fork of Hack (1985), which was itself a descendant of Rogue (1980). The codebase is in continuous development as of 2026. The game is a turn-based dungeon crawl rendered in ASCII characters. You descend through procedurally generated dungeons, fight monsters, collect items, and try not to die — or, more famously, ascend by completing a specific quest sequence.

Browser ports of NetHack run in any modern browser. The interface looks like a terminal, because it is a terminal. There’s a learning curve, but the game’s depth is unmatched — many roguelike enthusiasts consider NetHack the genre’s high-water mark even today.

2. MUDs (1978 onward) — still playable via web Telnet

The first MUD (Multi-User Dungeon) was created by Roy Trubshaw and Richard Bartle at Essex University in 1978. The genre seeded MMORPGs decades later. Many original-era MUDs (Achaea, BatMUD, MUME, DikuMUD descendants) are still online and still have active player bases. They run on Telnet, but browser-based Telnet clients let you play them in a tab without installing anything.

The gameplay is entirely text. You type “look,” the server describes the room. You type “go north,” you’re in a new room. Combat is real-time but command-driven. This is what online gaming looked like before graphics existed.

3. Pong (1972, recreated countless times)

Pong is older than the personal computer. The arcade cabinet shipped in 1972. The browser-based Pong recreations are not the original — there is no surviving Atari source playable in a browser — but dozens of HTML5 Pong clones recreate the game faithfully. The Wikipedia entry for Pong covers the original development if you want the full history.

If you want the simplest game on this list, this is it: paddle up, paddle down, hit the ball.

4. Tetris (1984, modern web recreations)

Tetris started on a Soviet computer in 1984. The legal status of unauthorized clones is a long story — the Tetris Company is aggressive about enforcement. That said, several authorized web versions exist, and the open-source clones (which often use different naming to avoid trademark issues) are easy to find in 2026.

The original gameplay holds up forty years on. Falling blocks, rotate to fit, clear lines.

5. Snake (origin in 1976, web versions everywhere)

Snake’s lineage starts with Blockade (1976) and continued through hundreds of variants on calculators, phones, and PCs. The Nokia mobile version in 1997 cemented it as a cultural fixture. Browser recreations of the basic Snake game are everywhere and trivially playable.

Google’s “Easter egg” Snake — accessible by searching “play snake” — is one of the most-played browser games quietly running today.

6. Yahoo Games archives (1998-2014)

Yahoo Games launched in 1998 as a portal for Java-applet board and card games — Chess, Spades, Hearts, Backgammon, Reversi, and many more. The service shut down in 2014. The games themselves were Java applets and stopped working in modern browsers years ago. However, an archive at the Internet Archive’s web archive preserves the game lobby pages, and a small number of dedicated fan projects have ported the gameplay (not the original code) to modern JavaScript.

This is the closest you can get to playing 1998-era browser games in 2026: archive screenshots, occasional fan-ported recreations, and a strong dose of nostalgia.

7. The Wayback Machine’s Flash game archive

The Internet Archive partnered with the Ruffle emulator project starting in 2020 to make Flash games playable in modern browsers. The archive hosts thousands of Flash games dating back to the late 1990s — including the original Stick Page, Newgrounds favorites, and countless one-off flash hits. The Ruffle emulator runs them in pure JavaScript and WebAssembly, no Flash plugin required.

The full archive lives at archive.org/details/flashgamearchive and equivalent collections.

8. AdventureLand text adventure (1978 lineage)

Scott Adams’s Adventureland (1978) was the first commercial text adventure. The game’s source code has been preserved and ported multiple times — a JavaScript port runs in modern browsers without any plugin. Two-word commands, room descriptions in prose, treasures to collect. This is text adventure in its earliest commercial form.

9. Falling Sand games (early 2000s lineage, modern ports)

The original Falling Sand Game (early 2000s, by Dofi-Blog) was a Java applet that became a browser-meme phenomenon. The Java version died with applet support, but several modern ports — Sandspiel being the best-known — recreate the original mechanics in pure JavaScript with extras. The lineage is over twenty years old; the gameplay is unchanged.

10. Town of Salem and Werewolf (online versions of older social deduction games)

Werewolf as a social deduction game predates the internet (Russian mathematician Dimitry Davidoff invented it in 1986). Online versions started appearing in the mid-1990s as IRC bots and BBS games. Modern browser versions (Town of Salem, Werewolf.com) are direct descendants. The mechanics — secret roles, lynch by vote, player elimination — haven’t changed in nearly forty years.

What stopped working and why

Most of the iconic 1995-2005 browser games are gone. The two main reasons:

• Java applets were the dominant interactive-browser technology from 1995 to about 2017. Modern browsers no longer run them. Most original Java browser games stopped working without warning between 2015 and 2018.
• Flash was the dominant technology from 2000 to 2020. Adobe ended support on December 31, 2020. Browsers immediately disabled the plugin. Hundreds of thousands of Flash games went offline. The Ruffle project and the Internet Archive recovered some; many are gone for good.

The games on this list survived for one of three reasons: they’re text-based (no plugin needed), they were ported to JavaScript or HTML5 by the community, or they predated the web entirely and were ported in.

Why the survivors survived

Notice the pattern: the games that lasted are either text-based (NetHack, MUDs, Adventureland) or so mechanically simple (Pong, Snake, Tetris) that any developer can recreate them in an afternoon. The complex Flash and Java-applet games of the late 1990s and early 2000s mostly died because no one was willing to port them and the originals required defunct plugins.

This is also why the Chrome Dino game — added to Chrome in 2014 — will likely be playable in 2050. It’s open-source, written in plain JavaScript, and the source code is mirrored across countless forks. You can play it right now in the browser Dino game on this page.

Where to find more

The Internet Archive’s collections of Flash, MS-DOS, and ZX Spectrum games are the deepest preservation effort online. Their browser-based emulators handle most of the platforms. If you want a deep dive into web game preservation, that’s where to start. For text adventures specifically, Frotz interpreters in browser can play any Z-machine adventure ever published, going back to the original Zork (1980).

Frequently asked questions

What is the oldest browser game still playable in 2026?

NetHack, in continuous development since 1987 and playable in modern browsers via official web ports. If we count online text-based games, MUDs dating back to 1978 are still playable via web Telnet clients.

Can I still play Flash games?

Yes, via the Ruffle emulator. The Internet Archive’s Flash game archive hosts thousands of titles that play in modern browsers without the discontinued Flash plugin.

Why don’t old Java browser games work anymore?

Modern browsers stopped running Java applets between 2015 and 2018 for security reasons. Most original Java browser games have no replacement; a small number have been ported to JavaScript by fans.

Is the original Chrome Dino game old enough to count?

The Chrome Dino game was added in 2014, so it’s only about a decade old. Compared to NetHack or MUDs, it’s recent. But it’s likely to outlast newer Flash-dependent games because it’s built on open web standards.

Where can I find a comprehensive archive?

archive.org hosts the most complete collection of preserved browser games — Flash, MS-DOS, ZX Spectrum, and other platforms. Their emulators run most of the archive directly in your browser.

The takeaway

The web’s gaming history is fragile. Most of what existed in 2002 doesn’t run in 2026 without an emulator. The games that survived survived because they were simple enough to port or because their source code was open and durable. For a contemporary example of a game built on durable web standards — and one that’s likely to keep running for decades — try the Chrome Dino game on this site. Open source, no plugins, no expiry.
