Roblox

Roblox is an online platform and game-creation system where users build, publish, and play 3D experiences made by other users. Rather than producing its own games, Roblox provides the engine (Roblox Studio), hosting, social layer, and a virtual currency (Robux) that lets a global community of creators turn ideas into playable worlds - and, increasingly, into income. With roughly 132 million daily active users and more than $1 billion paid out to creators in a single year, it has become one of the largest user-generated entertainment platforms in the world.
