Roblox is an online game platform and game creation system made by the Roblox Corporation. It allows people to create games and play games created by other people. It was created by David Baszucki and Erik Cassel in 2004 and released in 2006. The platform has many different types of games. "Roblox" began to grow fast in 2021. Roblox can be used on iOS and many systems, as it cannot be played on a browser. For example, if you try to play a game on a web browser, a message will come up telling you to open the game in the app.
