How to Make a Game With AI: From Your First Prompt to a Playable Game

You don't need to be an experienced developer to bring a game idea to life. Here's how to use AI to build, test, improve, and share your first game.

Almost everyone has imagined a game they'd love to play.

Maybe it's a puzzle game with a twist, a racing game set in a city you know, or a multiplayer world where players can create their own adventures.

The problem is that turning an idea into a playable game has traditionally required time, coding skills, art assets, and a lot of patience.

AI is changing that.

You can now describe a game in plain English, generate an initial version, and start playing without writing every line of code yourself. Tools like ForgeClan make this process more accessible by bringing AI game creation, live previews, iteration, and publishing into one platform.

But there's an important distinction: getting a game to run is not the same as making a game people enjoy playing.

The real process involves testing your idea, fixing what doesn't work, and improving the experience one step at a time.

Here's how to approach it, even if you're starting from scratch.

1. Start With a Game Idea You Can Actually Build

Before opening an AI game generator, decide what you want the player to do.

You don't need a detailed game design document. A simple idea is enough to get started.

For example:

• A runner where a robot jumps over obstacles and collects coins.
• A puzzle game where the board changes after every move.
• A clicker game where players earn points to unlock upgrades.
• A racing game where players navigate increasingly difficult tracks.

Notice what these ideas have in common: each has a clear gameplay loop.

The player does something, receives feedback, and decides what to do next.

For your first project, focus on one main mechanic. You can add new features later, once the basic game works.

This doesn't mean AI can only build simple games. More complex projects are possible, too. However, games involving multiple levels, inventories, multiplayer systems, or intricate progression generally require more planning and testing.

Starting small gives you something playable sooner, which means you can begin learning from the experience rather than spending all your time planning.

2. Turn Your Idea Into a Playable Game With AI

Once you know what you want to build, the next step is finding a tool that can turn your description into a working game.

One option is ForgeClan, an AI-powered game creation platform designed to help people go from an idea to a playable build.

Instead of assembling a development environment and writing the game from scratch, you describe the experience you want. ForgeClan Studio generates the game and provides a live preview so you can try it.

You can also start with a game template, including options for runners, puzzles, racing games, shooters, and RPGs, then customise the idea to suit your vision.

For example, you could take a standard endless runner and give it a more personal twist:

"A colourful endless runner set in Lagos. The player controls a danfo bus dodging potholes and collecting fuel. The game gets faster over time, and the player earns points for every obstacle avoided."

That gives you a starting point you can test and improve.

The result won't necessarily match every detail of your imagination on the first attempt. That's normal. The initial build is a foundation, not a finished product.

Try it yourself: Open ForgeClan and start with a game idea you've been wanting to explore.

3. Write Better Prompts for Better Games

The quality of your instructions can make a difference to the game AI generates.

A vague prompt leaves too many decisions open. A specific prompt gives the AI a clearer direction.

When writing your first game prompt, include five things.

The genre: What kind of game are you making?

The gameplay loop: What does the player do repeatedly?

The controls: How does the player interact with the game?

The objective: How does the player win, lose, or progress?

The visual style: What should the game look and feel like?

Here's a practical example.

A sample AI game prompt

Create a playable browser-based endless runner featuring a small robot in a futuristic city.

The robot must jump over obstacles and collect energy orbs. Use the spacebar on desktop and a tap control on mobile to jump.

The score increases as the player travels farther. Hitting an obstacle ends the run.

Use colourful pixel art, a readable interface, a start screen, and a restart button.

Make the game responsive so it can be played on desktop browsers and tablets.

This prompt explains the game, the controls, the objective, and the intended appearance.

It doesn't guarantee a perfect build, but it gives the AI fewer things to guess.

You can use this approach with ForgeClan or another prompt-based game creation tool. Start with a clear description, see what the AI produces, and use the result to decide what needs changing.

4. Test Your Game Before Adding More Features

You've generated the game. It opens, the character moves, and the main mechanic seems to work.

It's tempting to immediately add more levels, new characters, better graphics, and extra features.

Hold on for a moment.

Play the game first.

Can you understand the controls without instructions? Does the main mechanic work consistently? Is the objective clear? Does the restart button function correctly?

Try to complete a full round. Test what happens when you lose, when you reach a high score, and when you repeat an action several times.

If possible, let someone else play without explaining how everything works.

You might discover that the game is technically functional but confusing to a new player. Perhaps the obstacles appear too quickly, the score is difficult to see, or the player doesn't understand why the round ended.

These are useful discoveries. They give you specific problems to solve.

The goal at this stage isn't perfection. It's to establish a working foundation before expanding the project.

5. Improve Your Game One Change at a Time

This is where AI game creation becomes an iterative process.

Your first build might work, but the movement feels awkward. The jump is too high, the obstacles are too predictable, or the difficulty increases too quickly.

Instead of rebuilding everything, ask the AI to make a targeted change.

For example:

"Reduce the robot's jump height slightly. Keep its horizontal movement, jump duration, and collision behaviour unchanged."

Then test the result.

If the change improves the game, keep it and move on. If it doesn't, describe what happened and try a more specific adjustment.

This is also where a platform's workflow matters.

ForgeClan supports follow-up prompts, live previews, version history, and build-failure recovery. That gives creators a way to experiment with changes and return to an earlier version when necessary.

It's worth saving a version you like before making significant changes. AI-generated edits can introduce new problems, even when the original instruction seems straightforward.

A few habits make this process easier:

• Be specific. Explain what feels wrong rather than simply asking the AI to make the game better.
• Change one thing at a time. This makes it easier to identify which change caused a problem.
• Test after every important change. Don't assume that a successful build means the feature works correctly.
• Keep working versions. Save your progress before experimenting with major changes.

For example, instead of asking for better gameplay, explain that the player can avoid every obstacle by staying in one lane. Ask the AI to adjust the obstacle patterns so that players must make meaningful decisions.

That's a problem the AI can work toward solving.

6. Fix Common Problems in AI-Generated Games

AI can generate substantial amounts of game code, but it can still make mistakes. Knowing how to describe those mistakes helps you get more useful fixes.

The character falls through the floor

This can indicate a problem with collision detection, movement calculations, or the timing of physics updates.

Rather than repeatedly asking the AI to fix the game, describe the exact behaviour:

"The player sometimes passes through the platform while falling. Inspect the movement and collision logic and fix the issue without changing the jump height."

Then reproduce the problem and check whether the fix works.

For additional technical background, see MDN's guide to 2D collision detection.

The game forgets your progress

You finish a level, refresh the browser, and discover that your progress has disappeared.

This can happen when game state exists only in memory rather than being saved.

For a simple browser game, you might ask the AI to persist the player's score or unlocked levels using localStorage. However, browser storage isn't a substitute for server-side storage when your game needs shared multiplayer data, secure accounts, or synchronisation between devices.

After implementing a save system, test it by refreshing the game and checking whether the intended progress remains.

You can learn more in MDN's Web Storage API documentation.

The controls feel unresponsive

If keyboard presses or touch inputs don't behave as expected, the issue could involve input handling, expensive calculations, or other problems in the game loop.

Explain which action feels delayed and when it happens. Ask the AI to investigate the relevant input logic rather than rewriting unrelated parts of the game.

And if you want people to play on tablets, test the touch controls on an actual tablet or a suitable mobile browser. A game that works with a keyboard isn't automatically comfortable to play on a touchscreen.

The game looks unfinished

Sometimes the gameplay works, but the visual elements feel inconsistent.

The character might have one art style, the background another, and the interface a third. Animations might not match the player's actions.

A consistent art direction can help. Specify a colour palette, visual style, character design, and general atmosphere. For sound and animation issues, identify the event that should trigger each effect.

You don't have to accept every generated asset. Replacing one poorly matched image or sound can be more effective than regenerating the entire game.

7. Know When to Stop Prompting and Try Another Approach

Prompting is useful, but it isn't always the fastest way to solve a problem.

If the same bug survives several attempts, pause and reconsider the approach.

Is your instruction specific enough? Does the AI understand the behaviour you want? Is the problem caused by another part of the game?

You can ask the AI to inspect the relevant code and explain the likely cause before attempting another fix.

If the problem persists, a small manual code edit might be more reliable.

You don't need to become an expert programmer to benefit from understanding basic concepts such as variables, functions, event handlers, and collision checks. Even a little knowledge can help you recognise when a proposed fix doesn't address the actual problem.

The aim isn't to avoid code at all costs. It's to use whichever approach gets your game working reliably.

8. Publish Your Game and Let People Play It

A game becomes much more interesting when someone other than its creator can play it.

Once you've tested the main mechanics, controls, restart flow, and overall experience, consider sharing it with friends or other players.

ForgeClan lets creators publish games to the ForgeClan Store and share playable links. Players can try published games directly, giving creators a way to get their work in front of an audience.

You can also update and republish a game as you improve it.

Before publishing, run through a short checklist:

• Does the game load correctly?
• Are the controls clear?
• Do the win and lose conditions work?
• Can players restart the game?
• Have you tested it on the devices you intend to support?
• Have you checked for obvious bugs?

Then share the game and ask for feedback.

Watch where people get confused. Ask what they enjoyed and what they'd change. Their answers can help you decide what to work on next.

Can you make money from an AI-generated game?

Potentially, yes, although creating a game doesn't guarantee that it will attract players or generate income.

ForgeClan allows creators to publish games as free or paid listings in its Store. According to its published pricing information, the platform takes a 2% fee on paid sales, with the remaining amount going to the creator's wallet, subject to the platform's payment and withdrawal arrangements.

Before charging for a game, make sure you understand the platform's current terms, any third-party asset licences, and the responsibilities involved in selling digital products.

For your first project, focus on making something people genuinely want to play. Monetisation can come later.

9. Which AI Game Creation Tool Should You Choose?

There's no single tool that's best for every project. The right choice depends on what you want to create and how much control you need.

ForgeClan is worth exploring if you want to describe a game, generate a playable build, refine it through prompts, and publish it through the same platform. It also offers templates and a Store for sharing games.

General-purpose AI assistants can help you write game code, debug problems, and learn programming concepts. However, depending on your setup, you may need to handle the preview environment, hosting, and publishing yourself.

Other dedicated AI game creation tools may offer different approaches to generation, editing, and asset creation. Compare them based on the actual workflow you need rather than their marketing promises.

How much does ForgeClan cost?

ForgeClan's published pricing page lists a free Starter tier with 10 credits. Its paid credit packs are one-time purchases rather than monthly subscriptions:

• Starter: free, with 10 credits.
• Creator: $10 for 50 additional credits.
• Pro: $25 for 125 additional credits.
• Studio: $60 for 300 additional credits.

One credit corresponds to one build, including a build that creates or changes a game. The pricing page says failed or stopped builds are refunded.

Prices are listed in USD. Check the official ForgeClan pricing page for the latest terms before purchasing.

You don't need to buy several tools or subscriptions to get started. Begin with a small project and choose a workflow that fits your needs.

Final Thoughts: Your First Game Is a Starting Point

AI has made it easier to experiment with game ideas without first mastering an entire development environment.

You can start with a prompt, generate a playable prototype, test it, and gradually turn it into something more interesting.

But the process still requires creativity, patience, and judgment. You'll need to decide what makes your game fun, recognise when something isn't working, and test whether your changes improve the experience.

Start with one mechanic. Write a clear prompt. Play the result. Fix the biggest problem, save your progress, and repeat.

And when you're ready to bring your idea to life, ForgeClan is one place to start building, experimenting, and sharing your game with other people.

Your first game doesn't have to be perfect. It just has to be playable enough to begin.
