Roblox is a platform rather than a single game. One client gives you access to millions of experiences built by other users — obstacle courses, role-play worlds, tycoon simulators, horror games, competitive shooters — and your account, avatar, inventory and friends list travel with you between all of them.
The client is free. Money moves through Robux, the platform currency, which buys avatar items and in-experience purchases. Nothing is required to play, and a large share of the catalogue costs nothing at all.
Creation is the other half of the platform. Roblox Studio is a free tool for building and publishing experiences, using Luau — a dialect of Lua — for scripting. Creators earn a share of the Robux spent in what they build, and the developer exchange programme converts that back to real currency above a threshold. This is why the catalogue grows so fast: the people playing are also the people building.
Roblox runs on Windows, macOS, Android, iOS, Xbox and PlayStation, with cross-play between all of them — a group on phones, console and PC can share the same server. Parental controls cover spending limits, chat restrictions and age-based content filtering, which matters given how much of the audience is young.
Roblox Corporation has run the platform since 2006, developing both the client and Roblox Studio, the free tool its creator community uses to build and publish experiences.
