Use the official Roblox download page to find the app for your device. Fantasy Game does not host the Roblox installer or operate a Roblox login service.
Desktop installation
Roblox’s installation guide describes opening an experience after signing in and choosing Play. If Roblox is not installed, follow the installation prompt, then return to the experience and open it again.
When the browser asks to open the installed application, confirm that the request came from the official Roblox page you intended to use. Opening an experience page in a browser is different from running the experience in the app.
Mobile installation
Follow the device links from Roblox’s download page to the relevant official app store. Check the listed publisher and device compatibility before installing. Store availability and supported operating systems can change, so use the current listing instead of an old version number from a guide.
If the app will not open
Identify the stage that failed: download, installation, launch, sign-in or joining one specific experience. Record the error text and consult Roblox’s desktop troubleshooting page when appropriate. A problem with one experience does not necessarily mean the app needs reinstalling.
Before the first session
Review account privacy and purchase settings. For a child’s account, use Roblox’s documented parental controls rather than sharing a password. Installing the app is separate from optional purchases made inside it.
