Roblox is an online game platform and game creation system where users can create, share, and play games made by themselves or others. It was developed by Roblox Corporation and launched publicly in 2006. The platform enables users to program games using a version of the Lua programming language through Roblox Studio, its game development environment. Roblox is free to play, but it features an in-game currency called Robux, which can be used to buy virtual items and game passes, and creators can exchange earned Robux for real money. It has a large user base, especially popular among children and teenagers, and hosts a vast variety of user-generated games and experiences, appealing mainly to families and young audiences.
