Buying Robux worth $100 in Roblox and the process of buying it On May 15, 2007, Robux was created as a substitute for Roblox points. Robux was not the sole legitimate in-game currency at the time.

Robux is the in-game currency that is core to Roblox. Users can purchase various items, accessories, avatar upgrades and developer products and can even access games within the platform’s ecosystem.

Robux is a portmanteau of “Roblox” and “Bucks.” Robux is known as the primary currency, and currently, items in the avatar shop are sold in exchange for it.
