Google has launched Playground, a free tool that lets people make video games just by describing them.

Playground runs in a web browser and is open now to people in the U.S. who are 18 or older, The Verge reported. Google calls it an "experimental gaming platform" that does not require any coding. "With Playground's conversational interface, you can direct the game just by typing what you want to build," the company said.

Users can start from a blank page, remix a starter idea or follow step-by-step help. They can pick a 2D or 3D game, 9to5Google reported. Then they can ask Playground to change the physics, rewrite the rules or redesign the characters and world. Games can be played on a phone or laptop.

Finished games can stay private, be shared with a link or be posted to a public gallery called Playground Explore. Players can rate games, and some genres support leaderboards and multiplayer. Google says games are screened against its community rules, and users can report problems.

Playground is built on Google's existing AI models, Gemini, Nano Banana and Lyria, a Google spokesperson told The Verge. It is free, but Google One subscribers get higher weekly limits.

Google and game-engine maker Unity also showed Unity Spark, a more advanced tool for building games with others. Games made with Spark can be shared on Playground. A closed test is set to start later this year, and people can join a waitlist now.

Google is not alone. Meta recently said it will let people build games with AI for its Horizon platform, and Roblox is testing a similar feature, The Verge reported.

What we know: Playground is free for U.S. adults, with more use for paying Google One members.
What we don't: When Unity Spark will open widely.
