How to build a 3D game with AI — and play it on your phone

Making a 3D game used to mean learning a game engine. With Craftable you describe the game and the AI writes it with Three.js, a popular 3D library for the web. The game runs in the browser, so it works on phones and laptops, and you can share it with a link.

Start with one clear sentence

Say what the player does, how they win or lose, and the setting: “A 3D endless runner in a neon city where I dodge trains and collect coins.” Craftable builds a start screen, controls, score and a best score.

Or remix a free 3D game template

The fastest way to learn is to start from something that already plays well. These free templates cost 0 credits to start from:

• Turbo Rush — 3D racing: dodge traffic and collect coins.
• Sky Guardian — open-world 3D hero: fly over a blocky city, catch robbers, save civilians.
• Nova Strike — 3D space shooter with drones and power-ups.
• Marble Maze 3D — tilt a wooden maze to roll the marble to the goal.
• Sky Hopper — a one-tap 2D arcade game, perfect for a first remix.

Tap Build one like this, then ask for changes: “make the ship red”, “add a boss every 5 waves”, “make it harder after level 3”.

Controls that work on phones

Craftable games are built for touch: drag or swipe to steer, tap to jump or fire, big buttons for pause and restart, plus arrow keys on a laptop. If the controls feel off, just say so — “make steering less sensitive” is a valid request.

Make it yours

• Change the theme: “make it a monsoon Mumbai street at night”.
• Add sound effects and music.
• Add levels, lives, power-ups or a leaderboard saved on the device.
• Rename it and add your own title screen.

Share your game

Publish to get a link you can send to friends, deploy it to Vercel, Netlify or GitHub Pages, or export it as an Android APK.

Which plan for 3D?
