Can AI Really Make a Video Game? We Put It to the Test

On social media, two camps are at war. On one side, vibe coders saying "I made a game in one minute with ChatGPT". On the other, irritated developers pointing out that a video game isn't three hundred lines of JavaScript.

Both are right, and that's exactly what makes the question interesting. So we took it seriously: we asked AIs to create games and we tested the results.

Can AI create a complete video game?

First we have to agree on words, because "video game" means two very different things.

The studio game: out of reach

Dozens of hours of content, entire teams, proprietary engines, six figure budgets. Nobody serious claims an AI produces that today, and it isn't the subject of this article.

The mini game: the real testing ground

A few minutes of fun and one good mechanic. That's the format an AI can genuinely aim for, and the one we focused all our tests on.

So our question was the right version of the question: can an AI produce a complete, genuinely playable mini game?

Our test protocol for having an AI create a game

We deliberately kept a method anyone can reproduce at home.

• Five genres tested: an obstacle runner, a brick breaker, a quiz, a 2048 style puzzle, a small platformer.
• Three AIs: ChatGPT, Claude and Gemini, in their consumer versions.
• One absolute rule: not a single line of code written or fixed by hand. Everything goes through plain language requests.
• One imposed format: a single self-contained HTML file, with no external resources, so the game opens in any browser.
• One success criterion: the game has to be playable from start to finish by someone who read no explanation, on desktop and on a phone.

What AI genuinely gets right when it makes a game

Games with simple rules

Runner, brick breaker, Snake, fixed shooter: in those cases the first draft is almost always good. The game loop works, the score goes up, the run ends. The result isn't a broken prototype, it's a game.

That makes sense: those mechanics are so well documented that the model reproduces them reliably. If you're starting out, start there. A Snake or a brick breaker is the best possible first try, and our guide on creating a snake game with ai gives the exact prompt.

Quizzes and puzzles

This is where AI is most impressive, because it generates both the code and the content. A twenty question quiz on a specific theme, with a score and explanations, arrives complete on the first try.

Screens and presentation

Title screen, end screen, best score kept for the session, clean display: ask for them and you get them. That's what makes a game look like a real game, and AI does it very well.

What AI gets wrong when you ask it for a video game

Four flaws come back every time, whatever the model:

• Game feel: that's where it breaks. This is the main weakness. AIs almost always miscalibrate: games too hard from the first second, mushy jumps, excessive speeds. The code is correct, the fun isn't there. Good news: these are the easiest flaws to fix in plain language. "Slow the start down and ramp the difficulty up progressively" is often enough. We cover those settings in our guide on creating a platformer game with ai, the most demanding genre on that front.
• Mobile: forgotten by default. Across the five tests, no game was usable with a finger unless we asked explicitly. AIs write for a keyboard. You have to demand touch controls and vertical full screen every time, then check on a real device following our guide on testing an html5 game on mobile.
• Long projects: losing the thread. Beyond a certain size (roughly three or four interlocking mechanics and several hundred lines), fixes start breaking what used to work. You fix the jump, the enemies stop spawning. That's the hardest limit of the process.
• Graphics, sound, multiplayer. Visuals stay geometric: shapes drawn in code, no hand drawn sprites. Sound works if it's generated in code, not if you want real music. And online multiplayer is out of reach: it needs a server, so real development.

The verdict: yes for a mini game, no for a studio game

After the test, the answer is clear and not at all binary.

Yes, for a complete, publishable mini game

An AI can create a playable mini game on its own, start to finish. Count on fifteen minutes to two hours depending on the genre, with two or three rounds of fixes. Of the five genres tested, all ended up playable: quizzes and puzzles effortlessly, the platformer at the cost of several iterations on the jump.

No, for an ambitious project

It replaces neither a studio, nor an engine, nor a developer as soon as the project grows. And that's fine: it simply isn't the same category of product.

Reproduce our test: the prompt we used

Copy it, replace the brackets, and judge for yourself:

Build a complete web game in a SINGLE self-contained HTML file.
Mandatory technical constraints:
- all the HTML, CSS and JavaScript in the same file
- no external resources (no images, no fonts, no libraries)
- playable with a keyboard on desktop AND with a finger on mobile, full screen
The game: [your idea in two sentences]
Rules: [how you win, how you lose]
Difficulty: easy for the first 15 seconds, then progressive
Display: score and best score at the top, end screen with a "Play Again" button
Style: [colors, mood]
Give me the complete file, ready to open in a browser.

More variants, tailored to each genre, are gathered in our pick of the best prompts to create an html5 game.

The three fixes that improved our results the most

• "It's too hard from the start, slow it down and make the difficulty ramp up progressively."
• "Add touch controls and adapt the layout to phone screens."
• "Add an end screen with the score, the best score and a Play Again button."

Publishing the video game the AI made for you

Since the real obstacle is no longer building the game, you may as well tackle the one that remains: finding players.

Three steps to put your game online

For that there are platforms like Hoora that let you post your game for free and reach a pool of players already on the app. Go to hooragames.com and click the purple "Import" button in the left menu.

Drop in the .html file the AI gave you, keeping it under 100 KB, and you get a playable preview, the best way to check whether your game holds up before showing it. Title, description, publish. It's free, and your players install nothing and create no account. Every screen is covered in our guide on publishing your ai creations.

What the stats teach you

Your game joins the Hoora feed and you get a creator profile where players can follow you and see your other games.

It's also the best possible test of this article's question: does your AI generated game entertain players? The numbers answer better than any opinion. The app, available from Google Play or the App Store, also offers built in AI creation, if you want to test all this without even touching a file.

Frequently asked questions about AI creating a video game

• Can AI create a video game entirely on its own? Yes for a mini game, provided you accept two or three rounds of fixes. A fully successful game from a single request is still luck.
• Which AI should you choose to create a game? All three big ones hold up on mini games. See our comparison of chatgpt vs claude vs gemini for the detail.
• Do you need a paid plan for good results? Free versions are enough for a mini game. Paid versions mainly help hold longer files together across several fixes.
• Does the AI made game belong to me? You remain the creator of what you publish. The terms of AI tools regarding generated code keep evolving: worth a look at their conditions if you're aiming at commercial use.
• Does it replace a developer? No. It replaces the barrier to entry. A developer stays essential as soon as the project grows.
• Do players notice the difference with a handmade game? On a well tuned mini game, no. What they notice is badly set difficulty or broken mobile controls, so work on those two points.
• Once the game is published, how do you find players? The feed brings some, the rest is covered in our guide on how to promote and publish your video game.
• Do you need to code to run this test? No, everything happens in plain language. Our guide on creating a video game without coding starts from zero.

So the question is no longer whether AI can create a video game, but which one you'll ask it for first. Run the test yourself, the verdict fits in one evening.
