Roblox is a free game website in which users can create a Roblox character and interact with other Roblox characters on the site. You can also play a number of free games. Once you create a name for your Roblox you cannot change it unless you create a whole new profile. A new profile will not include any of your old profile's saved information.
Go to the Roblox website. (See Resources.)
Enter your new name and a password. The password must have four letters and two numbers.
Click "Sign Up." Enter your e-mail address and a friend code, if applicable, and click "OK, Done."
