The platform offers a toolbox with which own games can be built and programmed. At the same time, the company serves as a platform for the infinite number of created game worlds. Every user can choose whether they want to create a game themselves or play existing games. Furthermore, games can also be created in teams. The platform also offers friends and chat functions to get in touch with other players. The Roblox Studio is used to develop your own game worlds. There are no limits to the imagination here. The developers themselves can decide on the design, the type of game, and the rules of the game in their worlds. Each user has his or her own avatar, which can be designed according to preferences. In most cases, the games are available to users free of charge. However, certain areas and items in the game worlds as well as in the avatar marketplace may be blocked and must be bought with the in-game currency "Robux". One euro is equal to 80 Robux. This in-game currency is obtained by playing the game or by exchanging it for real money. Some of the Robux spent in the game are credited to the game developer and can be exchanged back into real money. In this way, game developers can earn extra money.
