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.

First things first; Robux isn’t free. Robux is ROBLOX’s premium in-game currency, which means that you have to use real world currency to purchase Robux for yourself to use.
