Google Labs Playground makes games from a prompt

Google Labs has launched Playground, an experimental browser platform where you describe a game in chat, test it, and ask for changes to the rules, physics, or characters.

You can keep a game private, share it by link, or publish it to the Explore gallery. Playground is open to people 18 and older in the U.S., with tiered creation access rolling out based on a Google AI subscription.

A Unity Spark integration is planned but isn't available yet.
