You can build games without coding experience, but you will need to learn one tool well

Game development starts with choosing an engine — the software that handles graphics, physics, sound, and the logic that makes a game run. The three most common free engines for beginners are Unity, Unreal Engine, and Godot. Each one works differently, runs on Windows, Mac, or Linux, and can publish to PC, mobile, or web browsers. You do not need to know how to code before you start, but you will spend weeks learning whichever engine you pick.

The actual path is: pick an engine, follow its beginner tutorials, build something small, break it, fix it, and build something slightly larger. Most people spend 40 to 100 hours on tutorials before they can make a game that works from start to finish. After that, the time to build a real game depends entirely on what you want to make — a simple 2D puzzle game might take a few months working part-time, while a 3D action game can take years.

Key Takeaways

  • Unity, Unreal Engine, and Godot are free and run on any computer; pick one based on whether you want to build 2D or 3D games and whether you prefer visual scripting or writing code.
  • You will need to learn the engine's interface, its scripting language or visual system, and how to import art and sound — this takes weeks of following tutorials, not days.
  • Start by building a small game from start to finish (a pong clone, a platformer level, a simple puzzle) rather than trying to build your dream game first.
  • Art, sound, and music can come from free asset libraries like OpenGameArt, Freesound, and itch.io, or you can commission them later once you know what you need.
  • Publishing to itch.io, Steam, or app stores is separate from building the game and involves its own steps, but you can test your game on your own computer first.

Choosing an engine: Unity, Unreal, or Godot

Unity is the most widely used engine and has the most tutorials online. It works well for both 2D and 3D games. You write code in C#, which is a real programming language but easier to learn than some alternatives. Unity publishes to PC, Mac, Linux, iOS, Android, PlayStation, Xbox, and Nintendo Switch. The free version has no revenue limit, so you can sell a game made in Unity without paying Unity anything until you earn over $1 million per year.

Unreal Engine is built for 3D games and is what professional studios use. It has a visual scripting system called Blueprints that lets you build game logic by connecting boxes instead of typing code — this is slower than writing code once you know what you are doing, but faster to learn at first. Unreal also publishes to most platforms. The free version charges 5% of revenue after your game makes $1 million.

Godot is smaller and newer but is growing fast. It is lighter on your computer, has a simpler interface than Unity or Unreal, and uses a scripting language called GDScript that is designed specifically for games. Godot is completely free with no revenue share. It handles 2D games better than Unreal and is easier to learn than Unity for beginners, but has fewer tutorials and fewer people to ask for help online.

Start with Unity if you want the most tutorials and the biggest community. Start with Godot if you want the simplest interface and do not mind fewer online resources. Start with Unreal if you are specifically interested in 3D games and like the idea of visual scripting.

Learning the engine through tutorials and small projects

Every engine has an official tutorial section on its website. For Unity, start with the Beginner Tutorials on learn.unity.com. For Unreal, the Learning section on unrealengine.com has guided projects. For Godot, the official documentation includes step-by-step tutorials. These are not optional — you cannot learn an engine by reading about it. You have to open the software, follow the steps, and watch what happens when you change things.

Plan to spend 40 to 100 hours on tutorials before you try to build your own game. This sounds long, but it is the fastest way. Each tutorial teaches you one piece: how to move a character, how to detect when something collides with something else, how to play a sound, how to save data. After you have done 10 or 15 tutorials, you will recognize these pieces and know how to combine them.

After tutorials, build a small game from start to finish. Good first projects are: a Pong clone (two paddles, a ball, score), a simple platformer level (a character that runs and jumps, platforms, a goal), or a match-three puzzle game (click to swap tiles, clear matches). The goal is not to make something fun yet — it is to learn the full cycle of building, testing, and finishing something that works.

Finding art, sound, and music without paying

You do not need to make your own art or sound to build a game. Free asset libraries exist specifically for this. OpenGameArt.org has 2D sprites, 3D models, and backgrounds. Freesound.org has sound effects. Itch.io has game assets, music packs, and complete art sets. Kenney.nl has clean, simple 2D and 3D assets that work well together. All of these let you download and use assets in your game for free, though some require you to credit the creator.

When you download an asset, check its license. Most free assets say "you can use this in your game, commercial or not, just credit me" or "you can use this however you want." Some say "you can use this only in non-commercial games." Read the license before you use it, because using an asset wrong can create legal problems later.

You do not need to have all your art before you start building. Many developers build the game first with placeholder art — simple colored squares and rectangles — and swap in real art later. This is faster and lets you test whether the game is actually fun before you spend time on art.

Writing code or using visual scripting to make things happen

Every engine needs you to tell it what to do. In Unity and Godot, you write code in a programming language. In Unreal, you can use Blueprints (visual scripting) or write code in C++. Visual scripting looks like connecting boxes with lines — each box is an action, and the lines show the order things happen. Writing code looks like typing instructions in a text editor.

Visual scripting is easier to learn but slower to write once you know what you are doing. Code is harder to learn but faster once you are comfortable with it. For a beginner, visual scripting (Unreal's Blueprints) or a simple language (Godot's GDScript) is usually faster to start with. You can always learn to code later.

The things you will write code or visual scripts for are: moving a character when the player presses a key, checking if the player touched an enemy, playing a sound when something happens, counting the score, and saving the game. Every game needs these same basic pieces. Once you have written them once, you can copy them into your next game and change the numbers.

Testing your game and fixing what breaks

Every engine lets you press a Play button and test your game right in the editor. Do this constantly — after you add a new piece, press Play and see if it works. If it does not work, the engine will show you an error message. Error messages look scary but they are usually telling you exactly what went wrong and where. Read the error, look at the line of code it points to, and change something small to fix it.

Most of your time building a game is spent testing and fixing. You will press Play, find a bug (something that does not work right), stop the game, change the code, and press Play again. This cycle repeats hundreds of times. This is normal and expected. Experienced developers spend more time fixing bugs than writing new code.

Test on the actual device you plan to publish to. If you are building for PC, test on your PC. If you are building for mobile, test on a phone or tablet. The game might run fine in the editor but break on the actual device because of performance, screen size, or input differences.

Publishing your game to itch.io, Steam, or app stores

Publishing is separate from building. You can build and test a game on your own computer for months before you ever publish it. When you are ready, you have several options.

Itch.io is the easiest. You create an account, upload your game files, write a description, and it is live. Itch.io takes no cut of your revenue if you set a price, or you can let people pay what they want. Most indie developers start here.

Steam requires you to pay a $100 one-time fee per game and fill out a detailed submission form. Steam handles payment, downloads, and updates for you. Steam takes 30% of revenue. You need a finished, polished game to submit to Steam — they reject games that are clearly unfinished.

App stores (Apple App Store and Google Play) have their own submission processes and take 30% of revenue. Apple requires you to own a Mac and pay $99 per year for a developer account. Google Play charges $25 one-time. Both have strict rules about what games they will accept.

Start with itch.io. It is free, has no approval process, and lets you update your game whenever you want. If your game gets popular, you can publish to Steam or app stores later.

Frequently Asked Questions

Do I need to know how to code before I start?

No. Unreal Engine's Blueprints system lets you build games with visual scripting. Godot's GDScript is designed to be beginner-friendly. Even in Unity, you can start with visual tools and learn C# gradually. Most people learn to code by building games, not before.

How long does it take to build a game?

Learning an engine takes 40 to 100 hours. Building your first small game takes another 40 to 100 hours. A medium game (like a complete platformer or puzzle game) takes a few months working part-time. A large game takes a year or more. The time depends entirely on the game's size and your experience.

Can I build a game on a laptop or do I need a powerful computer?

Any laptop from the last five years can run Unity, Godot, or Unreal. You do not need a gaming computer. The engines are free and designed to run on modest hardware. Your game might run slowly while you are building it, but that is normal.

What if I want to work with other people?

All three engines support version control systems like Git, which let multiple people work on the same game without overwriting each other's changes. You will need to learn Git separately, but it is a standard tool. Many game jams (short competitions where people build games in 48 hours) are good places to find teammates.

Can I sell a game I made with free assets?

Yes, as long as you follow the asset's license. Most free assets allow commercial use. Always check the license before you use an asset, and credit the creator if the license requires it. If you are unsure, contact the creator and ask.
