Roblox is a free-to-play online game creation platform and massively multiplayer gaming ecosystem developed and published by Roblox Corporation — founded in 2004 by David Baszucki and Erik Cassel as a physics simulation tool called DynaBlocks, publicly launched September 1, 2006, and now one of the largest interactive entertainment platforms in the world.

The platform's scale is staggering — 144 million daily active users as of Q4 2025, 380 million monthly active users, 73.5 billion hours played in 2024, and an audience where more than half of US children under 16 are registered users.
