ROBLOX used to be playable on its home page on the website; however, that has since changed as many more games created on ROBLOX have become more demanding. When downloading ROBLOX onto your PC, make sure that you are downloading it from the ROBLOX.com website only. Other sources may cause harm to your computer, and the only trustworthy source of the ROBLOX client download is via ROBLOX themselves. Firstly, make sure you have created a ROBLOX account here . It's really quick and simple, only requiring your birthday, custom username, and password to sign up. If you're below the age of 13, make sure you have a parent or guardian's permission before setting up an account. Once you've created an account, you'll be taken to a home page (as seen below), showing a profile image of your Avatar, which is your in-game character, username, and a set of games recommended for you and different games in different categories.
