How to Build a Game With AI

If you have been wondering how to build a game with AI, the practical answer is that it takes one prompt and about five minutes. You describe a character, something the player collects, and something the player avoids, and the model builds you a playable browser game while you sit and watch. There is no coding step, no engine to install, and no experience required.

I ran this live with a group of founders this week. I set a five minute timer and gave everyone the same starting prompt. By the time the timer went off, each of us had a game running in a browser tab. One founder looked at what they had made and said they were pretty blown away by it, off a simple prompt and about three and a half minutes of work.

How to Build a Game With AI in One Prompt

Here is the prompt I handed out, exactly as I wrote it:

That is it. Fill in the three brackets with anything you want and send it.

Mine became a dinosaur game for my son. He runs around collecting gems and avoiding dinosaurs. One prompt in, it was already playable.

The three blanks are doing real work. They force you to make the only three decisions a simple game needs, which is why the model can go straight to building instead of asking you a round of clarifying questions.

What Should Your First AI Game Actually Be About?

Make it something you would enjoy for its own sake.

That sounds like a waste of a session. It pays for itself inside five minutes. The founders on that call each picked something personal and the results told me more about them than an hour of coaching would have. One built a game where you collect assets and dodge liabilities, modelled on the Robert Kiyosaki cash flow game. One built a game about collecting good deeds and avoiding unkind ones. One built a cave explorer starring their own kid.

Every one of those took a single prompt. Every one of them worked.

The useful part shows up later. Right now you are buying yourself the experience of watching an idea in your head turn into a thing that runs, which is the experience that changes what you think you are allowed to attempt next.

How to Build a Game With AI That Looks Better Than Your First Try

Your first version will be flat. Mine was. Left, right, collect the gem, avoid the dinosaur.

So run one more prompt. Here is the one I used:

Two prompts in, my dinosaur game had a jungle, a buggy to drive, water and rocks that actually looked good, and sound effects. It is designed as a thirty second game and it went from a toy to something I wanted to show people.

If you want to push further, the next move is to feed it references. Ask the model to explain world class game design theory, then find games whose look you admire, screenshot them, and upload the screenshots as reference material.

One practical tip from the live session. If a build seems to be hanging for too long, stop it, edit your message, add a space, and send it again. That is the move I reach for whenever it happens.

Do You Need Coding Experience to Build a Game With AI?

No. Some of the people on that call had barely opened the new model before we started, and it made no difference to what they shipped.

What you need is a willingness to say the thing out loud. The model handles the rest of it. My whole approach to this is that you ask for what you want, look at what comes back, and then ask for the next thing. I have written more about that starting point in Claude Code for non-developers, and the same instinct applies to every tool you will touch this year.

If a build comes back wrong, you say what is wrong with it in plain language and send it back. That loop is the entire skill.

What Does Building a Game Teach You About Your Business?

This is the part I actually care about.

Once you have built one yourself, you can build one about the business you are actually in. You will not know another person who has built a video game with AI, and the more you see, the more you can see.

On that call, one founder said they get bored with the day to day of running their business but felt genuinely excited doing this, and wondered aloud whether they should spend three days building games and see if any of them stuck. Then they landed somewhere better. They said there is probably a way to gamify the most boring part of what they already do, and that they would start with their own team.

That is the whole return on a five minute toy. Someone who had been dragging themselves through their own operation found a live idea for it by building something with no business purpose at all.

I have written before about what's possible with AI and about how to dream bigger. Building a game is the cheapest way I know to make either of those real instead of theoretical.

How Do You Turn a Game Into Something Your Business Can Use?

Take the thing you already made and point it at work.

The move is to look at whatever your team dreads, whatever gets done late and grudgingly, and ask what it would take to make that feel like the game you just built. Scoring, streaks, a board people can see. You now know it is one prompt away, which is the part you did not know yesterday.

There is a second habit worth building here. When you make something you like, ask the model to turn it into a reusable template right away. Give it the version you liked as the reference, have it produce a template version, and keep that. Next time you want another one, you hand over the template instead of starting from a blank prompt. If you want more range on how you ask for things, how to get better output from Claude or ChatGPT covers the mechanics.

One caution while you are playing with image and video generation alongside this. I have no interest in AI headshots of myself looking jacked, because that tends to come at the expense of doing the actual work. I would rather show myself at the gym doing the thing. Use these tools in the way that serves you.

Your Next Five Minutes

1. Open your AI tool of choice and paste the three blank prompt. Fill in a character, a collectible, and an obstacle that make you smile.
2. Set a five minute timer. Do not plan it. Send it and watch.
3. Run the upgrade prompt on whatever comes back.
4. Show it to one person today.
5. Write down the most boring recurring task in your business and one sentence on what a game version of it would look like.

Impress Yourself This Week

The assignment I gave that group was simple. Between now and next week, build something that impresses you. Something you have never attempted before. Something where you look at it and think that is frontier level, and then bring it to show everybody.

That is the bar worth holding for yourself. Build the thing that makes you say you cannot believe you just did that.

And if you hit a point this week where you feel low or overwhelmed or ground down, open up an AI tool and make something. Get that juice back. Then point it at the work that matters.
