The Parent Developer's Guide to Building Games With AI

How to use ChatGPT or Claude to build browser games with your kids — no coding or game dev experience required

My son and I recently built a delivery truck maze. You drive delivery trucks through a maze of city streets to the right destination (bread truck to the bakery, flowers to the flower shop). There’s sparkles and audio feedback when you complete a delivery, points awarded, and increasing maze difficulty with each level.

I’ve been a developer for over a decade — web apps, APIs, infrastructure — but game dev always felt like a different discipline. Engines, physics libraries, sprite sheets. Then my three-year-old said “make me a game where a red car goes fast” and I opened Claude instead of Unity.

We made it. It was playable. He loved it. We’ve built dozens since.

Here’s everything I’ve learned about the process.

What You Actually Need

An AI chatbot. Claude, ChatGPT, Gemini — any of the major ones. The technique is the same across all of them.

A web browser. That’s it. We build simple HTML/CSS/JavaScript games that run in a browser tab. Completely sufficient for young kids. No installs. No build tools. No dependencies.

A kid with opinions. (This is the easy part.)

You do NOT need game development experience, knowledge of any game framework, art skills, sound design skills, or a CS degree (though it helps for debugging).

The Basic Flow

Here’s how a typical session goes in our house:

Step 1: The kid has an idea. “I want a game where a delivery truck drives through a maze.”

Step 2: You help translate it into a prompt. “Create a simple HTML game where the player drives a delivery truck through a maze using arrow keys. There are houses along the route — when the truck reaches a house, it delivers a package and the house lights up. Add a counter for deliveries completed. Keep it simple and colorful, suitable for a 3-year-old.”

Step 3: The AI generates code. You get back a complete HTML file with embedded CSS and JavaScript. Save it as .html, open it in your browser.

Step 4: The kid reacts. “Make the truck yellow.” “Add more houses.” “I want a warehouse where you pick up the packages first.”

Step 5: You iterate. Feed the feedback back to the AI. “Change the truck color to yellow. Add a warehouse at the start where the truck loads packages before delivering. Add more houses to the route.”

Step 6: Repeat steps 4-5 until the kid is satisfied or hungry.

That’s the entire game development cycle. Your kid’s imagination, an AI that writes code faster than you can explain what you want, and a browser.

Prompting Tips (The Practical Stuff)

After building a lot of these, here’s what works:

Start way simpler than you think.

Your first prompt should describe a game that a first-year CS student could build. One mechanic. One interaction. One thing on screen. You can always add complexity later, but starting complex usually produces buggy, tangled code that’s hard to iterate on.

Good first prompt: “Make an HTML game where a red circle follows the mouse cursor and collects yellow stars that appear randomly.”

Too ambitious first prompt: “Make a 2D platformer with multiple levels, power-ups, enemies with AI pathing, and a save system.”

Specify the audience.

Always mention that this is for a young child. It changes the AI’s output in useful ways: bigger click targets, brighter colors, simpler controls, more forgiving collision detection.

Ask for everything in one file.

“Put all HTML, CSS, and JavaScript in a single HTML file.” This makes it trivial to save and run. No build step, no dependencies, no module imports that break.

Request mobile/touch support.

“Make it work with both mouse/keyboard and touch.” Toddlers are surprisingly good with touchscreens, and this means the game works on your phone or tablet too.

When things break (and they will):

Copy the error from the browser console and paste it directly to the AI. “When I click the truck, I get this error in the console: [error]. Fix it.” Or if there’s no error, describe it: “When I press the down arrow, the page moves instead of the truck.” AI is excellent at debugging its own code.

What Your Kid Actually Learns

Here’s the part that surprised me: building games this way is sneakily educational, even though it feels like pure play.

Decision-making. Every feature request is a design decision. “Should the truck be fast or slow?” “What happens when you crash?” Your kid is learning to think about cause and effect in a system.

Iteration. The game is never right on the first try. Your kid learns that making things is a process of attempt → evaluate → adjust. That’s the most important meta-skill in all of technology.

Systems thinking. “When I added the dinosaur, the truck stopped working.” Things are connected. Changes have consequences. Welcome to software.

Creative expression. Your kid’s game is their game. Not a game they downloaded. Not a game someone else designed. It has their ideas, their aesthetics, their dinosaur-on-a-garbage-truck vision. That ownership compounds interest.

Common Pitfalls

Don’t optimize too early. Your kid doesn’t care about code quality. They care about whether the dinosaur is big enough. Ship the feature, clean up later (or don’t — these are throwaway games).

Don’t take over. It’s tempting to start adding your own ideas. “What if we add a leaderboard? What about particle effects?” Let your kid drive. Your job is to translate their ideas into prompts, not to impose your own.

Don’t expect polish. AI-generated games look like AI-generated games. They’re functional and fun, but they won’t win any design awards. That’s fine. Your kid genuinely does not care that the truck is a rectangle with two circles for wheels.

Don’t make it a lesson. The moment you say “this is teaching you about algorithms,” the magic dies. Just build. The learning happens in the background.

One More Thing

The games we build might be objectively terrible. The collision detection is approximate. The graphics are basic shapes. The physics are suggestions at best. My son’s current favorite is a car wash game – you literally wash a car. Click on water, click the car. Click on soap, click the car. Some elements overlap others and there’s a bug when you click on the sponge too early – but it’s fine. It works well enough and he’s played it about a hundred times already.

He made it. That’s why.

You don’t need game dev experience to give your kid that feeling. You need an AI, a browser, and the willingness to build a really, really bad game about garbage trucks.

It just might be the best thing you ship all year.
