Roblox is a popular gaming creation platform that sees millions of users playing daily. So what is Roblox, and why is it always thriving?

Like YouTube, Roblox started two decades ago as an online stage for young creators. Video-game lovers could use the service’s tools to develop inexpensive, low-resolution entertainment.

The average user plays the game for 2.5 hours a day, according to Roblox’s own figures, which were first cited by the Financial Times.
