Here's the trick to appear Offline on Roblox on your Windows PC or Mobile Phone and prevent users from communicating with you.

To download Roblox on a PC, you need to be running Windows 7 or newer. The gaming platform is also available on Mac, iOS, Android, and Xbox One.

If you're downloading onto the PC or Mac, head over to the Roblox website and create an account. Click on the play button on any of the games and you'll be prompted to download the Roblox Player.
