Every official site gets pinged on each sweep and every fact links to a source. The oldest listed game launched in 1997. Online means the official homepage answered; it doesn't mean every server is busy.
Era 1
Text MMOs, Java/Flash-era portals, persistent strategy and community sites.
55 games →
Era 2
Instant-join arena games in the mould of Agar.io (2015) and Slither.io (2016): type a name, press play.
55 games →
Era 3
Newer independent multiplayer games built on HTML5, WebSockets and WebGL: party games, puzzles, sims and worlds.
47 games →
History
How multiplayer games moved into the browser: text strategy games in 1995, Java card rooms, the Flash golden age, Facebook farms, the .io boom of 2015–2016 and today's WebGL and WebAssembly games.
Preservation
What actually happened when Adobe Flash Player reached end of life on December 31, 2020, which games closed or moved, and how emulation (Ruffle) and archiving (Flashpoint) stepped in.
Play together
Drawing games, word games, board games, shooters and party games that let you make a private room or share an invite link, with each game's own words on how it works.
.io
From the originals (Agar.io, Slither.io, Diep.io) to shooters, survival builders and territory games: every .io game we track, grouped by type, with live status.
Old guard
Text RPGs, space empires, football managers and virtual pet sites from the 1990s and 2000s that are still answering, with launch years and sources.
Some games outlive their owners: fan revivals, open-source remakes and emulators that keep old Flash worlds playable.
