Roblox is bringing AI game creation to mobile.

The new Build tool allows users to generate basic playable games directly within the Roblox mobile app using natural language prompts. The system handles gameplay mechanics, environments, and characters, letting creators iterate on and publish their projects without leaving the app.

Testing begins in New Zealand on July 28 for age-verified users aged 9 and older. While a basic version will be free, Roblox plans to offer paid options with advanced capabilities.
