To get your Roblox login, all you need to do is create a username and password, then add your birthday and gender. And then, after you’ve accepted all the necessary terms and conditions, you’re ready to start your Roblox download. The Roblox download is only a small one, too, at roughly 2MB.
To download Roblox, play most of the games it hosts, and sign up, is completely free. But there are some games, cosmetic items, and building tools that require Roblox’s virtual currency: Robux.
Robux can either be bought with real money or earned by creating popular games. If you create a game that pulls in many players you can get a share of the revenue from in-game ads and even charge for access to your games. You can also choose to pay for the optional Roblox Builder’s Club which lets you go ad-free and join more groups.
