About this site

Radiant Optimizer Games is a directory of games you can play in your web browser. We collect classic PC games, fan remakes and community ports that run in a browser tab, from Quake and Half-Life to Black Ops zombies maps and Skate 3.

For every game we explain what it is, whether it plays instantly or needs your own game files, which devices it works on and how to get started. Genres, filters and collections help you find something to play in seconds, with no account and nothing to install.

We do not host, modify or distribute any game files. Every Play button opens the original project's own site. If you run a project listed here and want it changed or removed, email info@radiantoptimizer.net and we will act quickly. Know a browser game that belongs here? Send it through the Submit page.
