Riffgame: AI 3D Game Maker

Build playable 3D games with a single prompt. No code — your friends play in any browser. Start with 50 free riffs. Made for the vibe-coding generation.

Riffgame is the first AI 3D game maker for your phone.

Type your idea in plain language. An agent reads your prompt, picks the right components from a curated React Three Fiber library, writes the code, compiles it, and tests it in a real browser before publishing. You get a playable URL back. Open it in Safari. Send it to a friend.

HOW IT WORKS

1. Open the chat and describe the game you want. "A parkour runner with rooftops and neon crystals."
2. Watch the agent build it live — every skill it reads, every file it writes, every iteration of the compile and test loop is visible in your chat thread.
3. Tap Play. Your game opens in your phone's browser, full screen, with touch controls already wired.
4. Share the link. Anyone with the URL can play instantly. No App Store, no install, no sign-in.

WHAT YOU CAN BUILD

Endless runners, top-down crime cities, first-person shooters, drift racing, puzzle platformers, tower defense, side-scrolling beat-em-ups, twin-stick shooters, parkour scenes, racing AI cars, low-poly worlds — anything you can describe in a sentence or two.

MOBILE FIRST

Every Riffgame is built for a phone-portrait viewport. The agent automatically adds an on-screen joystick, action buttons, and game state HUDs.

A CREATOR'S WORKFLOW

Riffgame mirrors the way a working coding agent feels. You see the tool calls, the build logs, the smoke tests. When something runs long or hits an issue, the agent tells you, fixes it, and keeps going. The chat is the workspace.

OPEN BY DEFAULT

Games are real React Three Fiber and Three.js projects. Pro subscribers can export the source. Nothing about your game is locked into Riffgame's app.

PRIVATE BY DEFAULT

You sign in anonymously. You can link a Google or Apple account later to back up your library. Your prompts stay yours. Games are public only by URL — no one finds them unless you share the link.

SUBSCRIPTIONS

Riffgame Pro is an auto-renewing monthly subscription. Cancel anytime in iOS Settings, Apple ID, Subscriptions. Optional one-time top-up packs are available for users who prefer to pay as they go.
