Robux is the currency for roblox
Robux is virtual currency in roblox search it on google and you will see what is it used for.
Robux is the currency on Roblox, which you can use for buying cosmetics such as hats, different color etc. You can only get it from buying it as far as I know, and gamehag buys it for you when you get the reward Robux. I don't think it would be a really good idea for you to get that reward on this website since you don't use Roblox anyways. But it is your choice of course.
