Playing Roblox on a school Chromebook can be rather tricky. These Chromebooks may come with built-in safeguards that prevent you from accessing games and certain websites.

Play Local Games With Steam Or Google Play Store If your Chromebook has beefy enough hardware, you can run games on the computer itself using the Google Play Store or Steam.
