Hi

It is not possible to play Roblox directly on now.gg. now.gg is a website that allows users to earn virtual currency called Robux for the online gaming platform Roblox, by completing surveys, watching videos, and participating in other activities on the site.

To play Roblox, you will need to download the game or access it through a web browser, and create or log in to an account on the official Roblox website.
