The Best Prompts to Create an HTML5 Game with AI

You want to create a game with an AI, but the result is bland: limp mechanics, a confusing scoring system, or just a game that's unplayable. It's frustrating. Yet these same tools can create incredible games for you. The only difference is the prompt.

What is a good prompt?

An effective prompt always spells out these 5 things:

The format. A single HTML file, with no external resources.
The orientation. Portrait 9:16 for mobile.
The controls. Mouse and touch.
The goal. Score, end condition, replay button.
The feel. Animations and visual feedback.

If you leave one out, the AI will hand you a result of random quality.

Keep this base prompt handy, and simply replace the "Concept" line:

Create an HTML game for me in a single standalone file (HTML, CSS and JavaScript included in the same document, no external resources, no libraries to download). Portrait 9:16 format, playable with mouse and touch. The game starts immediately on load, with no start screen. Concept: [your idea in one sentence]. Add a score at the top, a game over screen with the final score and a "Play Again" button. Polish the animation and visual feedback.

For the general method behind this kind of prompt, see our guide on creating a game with ai.

Prompts by type of game

The endless runner, Flappy Bird style

The great mobile classic: simple, addictive, perfect for a first try.

Create a Flappy Bird-style game in a single standalone HTML file (HTML, CSS and JS included, no external resources). Portrait 9:16 format. The character goes up with every tap or click and falls back with gravity. Obstacles scroll from right to left with a gap to get through. Score +1 per obstacle cleared, shown at the top. Collision = game over screen with the score and a "Play Again" button. Add a small visual effect on a successful pass and a slight speed-up over time. The game starts on the first tap.

The clicker

No reflexes needed and a satisfying progression, ideal for testing a world idea.

Create a clicker game in a single standalone HTML file (no external resources). Portrait 9:16 format. One big central button: each tap adds points. Offer three upgrades you can buy with points (for example auto-click, multiplier, bonus), listed under the button. Animate a small floating "+1" and a bounce on every click. Score clearly visible at the top, kept in memory during the session.

The brick breaker

Rhythmic, visual, satisfying, perfect for showing off a bit of game feel.

Create a brick breaker (breakout) game in a single standalone HTML file. Portrait 9:16 format. Paddle at the bottom controlled by finger and mouse, a bouncing ball, rows of bricks at the top. Score +10 per brick, shown at the top. Three lives: losing the ball costs a life, zero lives = game over screen with a "Play Again" button. Victory when all the bricks are broken. Add an effect when a brick breaks and a ball that speeds up slightly.

The obstacle dodger

Simple, tense survival, where the difficulty rises on its own.

Create an arcade dodging game in a single standalone HTML file. Portrait 9:16 format. A character at the bottom moves sideways by finger and mouse, obstacles fall from the top at increasing speed. The score is the survival time, shown at the top. Collision = game over screen with the score and a "Play Again" button. Add particles on collision and a slight screen shake.

For two other formats that are just as easy to generate, see our guides on creating a snake game with ai and creating a 2048 puzzle game with ai.

Three prompts to go from prototype to real game

Once you have your first version, don't start over. Send these requests in the same conversation.

To adjust the difficulty.

The game is too easy or too hard. Add progressive difficulty: speed up and thicken the obstacles over time, and show a small level message every ten points.

To add game feel.

Add some feel: particles at key moments, a slight screen shake, small sounds generated with Web Audio (no external file), and a satisfying animation on the "Play Again" button.

To lock down mobile.

Make the game perfectly playable on mobile in portrait: smooth touch controls, large tap areas, page scroll blocked during play, and fit to the phone's full screen.

Publishing the game you got

Once the game is done, you can download it as an .html file, and to make it playable by the whole world, go to hooragames.com and click the purple "Import" button in the left-hand menu, then drop in your file. It's free, and the only limit is a maximum file size of 100 KB. If the file is already sitting in your downloads, our guide to turning an html file into a playable online game covers the same steps.

The Import button in the Hoora website side menu

Your game instantly becomes playable by the Hoora community! You'll find it on the website as well as in the app, which you can install from Google Play or the App Store.

You have your game, now the platform brings you the players. For the step-by-step import, see our guide on publishing your ai creations.

Frequently asked questions about HTML5 game prompts

Do these prompts work with every AI? Yes. ChatGPT, Claude, Gemini, Mistral or Copilot all produce usable standalone HTML. The result depends mostly on how precise the prompt is and how many iterations you do, not on the model. To compare, see our guide on which AI to choose to create a game.
Why always ask for a single HTML file? Because a standalone file runs everywhere, with no installation and no dependency that breaks. It's also the format that imports and publishes in one click.
My game is too hard or too easy, what can I do? Don't start over. In the same conversation, use the difficulty adjustment prompt above: the AI edits the existing code.
The game doesn't work well on mobile, why? Most often because it was built for a keyboard and a big screen. Explicitly ask for portrait 9:16 and touch controls, then see our guide to testing an html5 game on mobile.
Do you need to know how to code to use these prompts? No. You copy, paste, and get the file back. Reading a bit of code helps with fine-tuning, but it's not needed to publish.
How do I bring players to my game? The feed brings in some of them, and the rest comes down to a few simple moves, covered in our guide on how to promote and publish your video game.
Where do I publish my game once it's made? On the Hoora website, with the "Import" button. It becomes playable by the community, with no hosting to set up.

Now it's your turn to play! Pick a game, iterate two or three times, test it, and by the end of the evening you'll have a great game to share with the world.
