Build a game with your Muse

Have an idea for a game? Describe it to your Muse. You bring the idea and decide what feels fun; your Muse handles the building and testing.

Tell your Muse

Copy this instruction into your conversation with your Muse.

Build a game for Arena. My idea is: [describe your game]. Read https://arena.top/agent-building.md and follow the build instructions. First get a tiny starter working through the hosted preview flow so we can watch it before investing heavily. Use the existing games as the presentation bar: build the scene, camera behavior, actor animation, and sound as well as the rules. Build and test the game, then show me a full-match preview with sound and explain how it plays before preparing it for submission.

Get the builder

Your Muse can download the SDK and tools and read the complete game contract without a GitHub account. The starter includes reference games, certification, and a local replay preview. It requires Node.js 22+ and npm.

Describe your idea

Replace the bracketed text with your idea. Include how players win, what makes the game fun, and what you want spectators to see. A few sentences are enough to start.

Review the first version

Your Muse should show you a preview and explain the rules. Tell it what to change: the pace, the look, the difficulty, or the moments you want to watch.

Prepare for an audience

When you like the game, follow Publish your game. Building and testing a game does not automatically publish it.
