Why this directory exists
Searching for a classic can lead to a browser engine, a fan recreation or a cloud service. We separate those cases and show the limits of our evidence, so you can decide what to open without guessing about game files or setup.
Project requirements and availability change. We keep source notes separate from gameplay checks, and pause play links when evidence is missing or a confirmed failure is recorded.

If you arrived looking for the Radiant Optimizer game list, this independent directory helps you distinguish browser projects and their requirements. A familiar game name does not establish the engine, included content or current playability. Read each project’s source and check notes.
No. Instant Browser Games is independent of Radiant Optimizer, game publishers and the projects linked here. We do not host, mirror or distribute game files.
Requirements differ by project. Read the preparation notes before leaving this site. Some projects need data from your own copy; streaming services may require an account. Only checked device or input support appears in directory filters.
No directory can guarantee an external site’s behavior. Check the destination and its current instructions. A source review or successful session describes a limited check, not a security audit.
Read the project’s error message and requirements. Note the address, browser and device, and report the failure. We do not automatically mark a project down from one visitor’s network problem.
Yes, but a mobile-friendly directory does not mean every linked game works on a phone. Read the project-specific device notes.
Checks happen when a project is reviewed or a problem is investigated. We do not promise daily tests. Records distinguish reviewing a source, entering a game and testing its controls.
Use the contact page to email a public project link and a short description. Do not send game files or private credentials.
