Sites Like Radiant Optimizer

These projects offer other ways to find browser games. They are independent destinations, with different catalogs, requirements and availability; none is represented by this directory.

• DOS Zone — a large browser-game collection organized by title and genre, with many DOS-era entries.
• Internet Archive’s MS-DOS games collection — a software preservation collection; check individual items for browser-emulation support and metadata.
• RetroGames.cc — a console and arcade catalog organized by system; JavaScript is required for the site.
• Q3JS — a focused Quake III browser multiplayer project with a server browser, rather than a broad archive.

Choose by what you need

Start with a broad collection when you are browsing older titles. Use a project’s own documentation when you need exact file formats, controls or supported browsers. A collection listing is not a guarantee that a particular game loads on your device.
