Roblox

About

As of 2026, it's 20 years old.

Roblox is less a game than a sprawling digital playground where the games are made by other players — many of them children — which means it's somehow both an empire and a craft project. Launched in 2006, it exploded into one of the most-played platforms on Earth by simply letting kids build the fun for each other.

Its in-game currency, Robux, has fueled a genuine creator economy and an equal number of parental conversations about screen-time spending.

Endless, chaotic, and kid-powered, Roblox is the game that grew up to be a platform — and quietly took over a generation's after-school hours.
