Play Best Free Online Games

Ever thought about making your own browser game?

You’re playing a simple game online, maybe dodging blocks or matching colors, and suddenly you wonder—"Wait, could I build something like this myself?"

The answer is: absolutely yes.

You don’t need to be a coding wizard. You don’t even need to know what half the buttons in your code editor do. If you’re curious, a little patient, and okay with breaking stuff and fixing it again, you’re already halfway there.

This guide walks you through the basics of making your very first HTML5 game. No complex jargon. No huge downloads. Just you, your browser, and a little bit of code.

What You’ll Need (It’s Not Much)

• A computer with a browser (Chrome or Firefox works great)
• A simple code editor (try Visual Studio Code)
• A cup of coffee or tea doesn’t hurt either

Languages You’ll Be Using

Don’t worry—we’re keeping this lightweight:

• HTML for the game layout
• CSS for how things look
• JavaScript to actually make the game work

It’s like building a mini website, but it moves.

Let’s Build a Simple Game: The Jumping Box

1. Set Up Your Files

Create a new folder called jumping-box and inside it, make these files:

• index.html
• style.css
• script.js

2. Add Basic HTML

In index.html, put this:

  

3. Style It Up

In style.css:

body { margin: 0; background: #eee; }

#game-box {

  width: 50px; height: 50px;

  background: crimson;

  position: absolute;

  bottom: 0;

  left: 50px;

}

4. Make It Jump

In script.js:

const box = document.getElementById('game-box');

let isJumping = false;

window.addEventListener('keydown', function(e) {

  if (e.code === 'Space' && !isJumping) {

    isJumping = true;

    box.style.bottom = '150px';

    setTimeout(() => {

      box.style.bottom = '0';

      isJumping = false;

    }, 300);

  }

});

Now open index.html in your browser. Tap the spacebar. Boom—your red box jumps!

Where to Go From Here

This is just a taste. From here, you can:

• Add obstacles and collisions
• Make the game track score
• Add sound effects and a start screen

Once you're feeling confident, you can explore game frameworks like Phaser or Three.js to build more advanced stuff.

Where Do You Host It?

Try platforms like:

• GitHub Pages – free and easy to set up
• Netlify – drag-and-drop site hosting
• itch.io – great for sharing indie games

You can also embed it directly on your own website if you’re running one.

Final Tip: Don’t Worry About Making It Perfect

Your first game won’t be a masterpiece, and that’s totally fine. The fun is in building something that actually moves, reacts, and (eventually) entertains someone.

Start small. Break things. Fix them. Repeat.

And most of all—enjoy the process. You’re now officially a game developer (even if your box only jumps).
