Radiant Optimizer Games Not Working: Troubleshooting Steps
When a Radiant Optimizer game does not open, the issue may be the original host, a large first download, browser storage, or device compatibility. These checks separate a temporary load problem from a broken source link.
Confirm the original host
Open the detail page and verify the destination host before trying another mirror.
A source outage cannot be fixed by changing the directory URL.
Try a clean browser session
Use a current desktop browser or a private window to rule out stale cache and extension conflicts.
Allow JavaScript and keep the tab open while assets load.
Check controls and device
Click the game canvas to focus keyboard input.
If the entry is marked Desktop, do not expect a complete mobile control layout.
Report a persistent issue
Include the title, browser, device, source URL, and visible error text when reporting a broken link.
Do not install unknown EXE, ZIP, or extension files to make a browser game work.
Frequently asked questions
Should I keep refreshing?
No. One refresh is reasonable; repeated refreshes can restart a large asset download and make diagnosis harder.
Who fixes the original game host?
The original project host controls its server and build. The directory can check and update its link.
