Roblox: 4500 Robux
Robux is the in-game currency of Roblox. It costs REAL money to get. It basically lets people buy stuff in games to make them easier or more fun to play. You can also buy certain items like hats, shirts, outfits, etc. with Robux. Some games cost Robux to play at all, though. Most games allow people to buy VIP (private) servers with Robux if they want to play with just their friends. But you don’t need Robux to still have fun on Roblox. You can still play with friends, still get cool outfits and accessories. It’s just harder to.
