Free game-making skill v1.0.0

Got an idea for a game? This free skill helps AI tools such as Claude Code and Codex bring it to life. They write the code. You choose what to make and try it as it grows. Add your own brand, or just make something for fun.

Why we made it.

Matt and Steve made games together at Luna Labs before Atlas51. The Arcade lets us bring that fun back.

Our first game took about a week. More recent ones have taken hours, mostly with Claude Code and sometimes Codex. When someone can play an idea, it is easier to see what feels fun and what needs work.

Watch one idea grow.

Make it move

You and your helper

Start with one small thing you can play.

Find the look

Your coding helper

Try a few ideas for how it could look.

Build the detail

Your coding helper

Bring the chosen look into the real game.

You

Play Tuk-Tuk Pakistan

Play it. Say what you think. Change it. Play again.

An example of a Tuk-Tuk going from simple shapes to detailed artwork. The first three pictures are illustrations. The last is from our game. Yours might stay 2D or take a different route.

First, you and your coding helper agree what the game is for, what the player does, how it should work on a phone and what done means. Your helper makes a small version you can play and a picture of how the game could look.

You play it, choose what you like and say what needs work. Your helper adds detail to the real game, checks the controls and performance, then fixes things. You can jump in whenever you like. You make the final call on whether it is ready.

Our tip: if you have an image tool you like, bring it along. It's a handy way to try out a few looks and show your coding helper what you have in mind. You can make a game without one, though. Image tools come separately, so yours may need a little setup, an account or a paid plan.

Nobody wants to wait around for a game to load. The skill gives your coding helper a target of under 5 MB for the initial gameplay download, with checks to help it get there.

What you get for free.

OpenAI skills documentation

You need Claude Code, Codex or a similar AI coding tool on your computer. It needs to work in your project folder and test the game. The skill is free. Your coding tool, AI use and optional tools can cost money.

Pick only the tools you need.

The skill helps your coding helper choose optional tools such as Godot, Blender and Three.js. They do not come in the download. Before it uses one, your helper checks what you have and explains any setup you need. It can help with setup when your computer lets it.

Simple browser game

The included starter is a web game. You do not need any of the tools below.

Three.js

A tool for making 3D scenes in a browser. Add it only when your game needs it. Follow the installation guide.

Godot

An app for making a game and putting it on the web. Install it separately if your game needs it. Web versions also need its extra export files.

Blender

An app for making 3D models and art. Install it separately if your game needs it, then make it available to your coding helper. See Blender setup.

Start with your idea.

Add a few details, then copy this into your AI coding tool after installing the skill. It stays in your browser until you copy it. Your coding helper is the AI tool that writes and changes the game code for you.

Your game request

Paste this into Claude Code, Codex or another coding helper after you install the skill.

Use the make-it-playable skill to turn this into a small browser game.

Game idea: [Describe the game idea]
Players: [Who is going to play it?]
Do not add a brand or make one up.

Start with a short plan, then make a small first version I can play in a browser. Ask me to try it and use what I say before spending more time on artwork or sound. Check the controls and how hard it feels. Make sure it works in a browser and is easy to start. Try to keep the first game download under 5 MB. Check the download size and tell me what you tested and what still needs work. Leave me a game I can run, with clear steps to try it.
