Riffgame: AI 3D Game Maker

Describe a game in a sentence. Riffgame's AI builds it, tests it, and hands you a playable link.

Type "a parkour runner across neon rooftops" or "a drift racer through a night city". An AI agent reads your idea, writes the code, compiles it, and plays it in a real browser to check it works. A few minutes later you tap Play and your game opens full screen, with touch controls already wired.

Then send the link to anyone. They play instantly in their browser. Nothing to install.

HOW IT WORKS

1. Open the chat and describe the 3D game you want.
2. Watch the AI build it live — every file it writes and every test it runs streams into your chat.
3. Tap Play. Your game opens in your phone's browser with an on-screen joystick and buttons.
4. Share the link. Anyone who opens it plays straight away.

WHAT PEOPLE MAKE

Endless runners. Open-world driving. First-person shooters. Drift racing. Puzzle platformers. Tower defense. Survival and horror scenes. Space shooters. Parkour courses. Low-poly worlds. If you can describe it in a sentence or two, the AI will try to build it.

BUILT FOR A PHONE

Every game targets a phone screen in portrait. The AI adds an on-screen joystick, action buttons and a HUD without being asked. The chat composer is built for one thumb.

YOU CAN SEE THE WORK

Riffgame shows you what the agent is doing rather than hiding it behind a spinner: the files it writes, the builds it runs, the tests that pass and fail. When something breaks, it tells you what it is trying next.

REAL PROJECTS, NOT A WALLED GARDEN

Games are genuine React Three Fiber and Three.js projects running on WebGL. They play in any modern browser on any device. Pro subscribers can export the full source, so nothing you make is trapped here.

YOURS BY DEFAULT

You start anonymously — no email, no sign-up form, nothing to fill in. Your library lives on your device, and purchases restore whenever you need them. Your games are reachable only by their link and are never listed in search.

RIFFS

Building a game spends riffs. New accounts get a free grant to start with, and you can top up with one-time packs or subscribe.

RIFFGAME PRO

Riffgame Pro is an auto-renewing subscription billed monthly at the price shown in the app. It includes a monthly riff allowance, up to three builds at once, and source export. Payment is charged to your Google Play account at confirmation of purchase.
