Google launches Playground, a Gemini-powered platform for building playable games with prompts
Google has introduced Playground, an experimental gaming platform that lets users create playable 2D and 3D games through natural-language prompts instead of traditional coding workflows. The system is designed around a chat interface, allowing users to start from scratch, modify starter prompts, upload images such as pet photos, and iteratively adjust gameplay, physics, characters, and environments after a game is generated.
According to Google, Playground is built with a combination of Gemini, Nano Banana, and Lyria, alongside a custom harness developed internally and refined through in-house games and evaluations. Gemini handles language and code-related work, Nano Banana focuses on image generation and editing, and Lyria generates music. Google has also added a sharing layer through Playground Explore, where users can publish games, distribute playable links, and in some cases enable multiplayer modes and leaderboards through Play Games integration.
At the same time, Google and Unity announced Unity Spark, a new product planned for a closed beta later this year. Unity Spark is expected to keep the prompt-based creation model while adding more advanced development features, including complex game mechanics, high-fidelity 3D, and Unity Runtime. Unity CEO Matt Bromberg said AI can reproduce an existing game, but that alone does not make someone "the next Hideo Kojima."
