๐ฎ Build Your First Browser Game with Phaser โ A Beginner's Guide
Ever wanted to build your own web-based game โ something you can share instantly with friends in a browser? Good news: with Phaser, you can.
Phaser is a powerful yet beginner-friendly HTML5 game framework that makes it easy to create fast, beautiful 2D games using JavaScript (or TypeScript). In this tutorial, you'll learn what Phaser is, how to set it up, and how to create your first playable game step-by-step.
๐ง What Is Phaser?
Phaser is an open-source framework built specifically for browser games. Itโs the engine behind thousands of popular indie games and prototypes.
Why developers love it:
- โ๏ธ Works in any browser (desktop or mobile)
- ๐น๏ธ Handles physics, animation, sound, and input easily
- ๐ก Supports both Canvas and WebGL rendering
- ๐ Great for 2D games: platformers, puzzles, shooters, clickers
If you can write a little JavaScript, you can make a game in Phaser.
๐งฐ Step 1: Setting Up Your Environment
You donโt need anything fancy to get started โ just a text editor and a browser.
Option 1 โ Local setup
- Create a new folder:
my-phaser-game - Inside it, add an
index.htmlfile and agame.jsfile. - Download Phaser from the official site or use a CDN:
<script src="https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.js"></script>Option 2 โ Online editor You can also start instantly in CodePen, JSFiddle, or Phaser Sandbox.
๐ Step 2: Basic Game Structure
Every Phaser game needs a configuration and a scene. Here's the simplest template to get you started:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>My Phaser Game</title>
<script src="https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.js"></script>
</head>
<body>
<script>
const config = {
type: Phaser.AUTO,
width: 800,
height: 600,
backgroundColor: '#87CEEB',
physics: { default: 'arcade' },
scene: {
preload: preload,
create: create,
update: update
}
};
const game = new Phaser.Game(config);
function preload() {
this.load.image('player', 'https://labs.phaser.io/assets/sprites/phaser-dude.png');
}
function create() {
this.player = this.physics.add.image(400, 300, 'player');
}
function update() {
// Simple movement logic
const speed = 200;
const cursors = this.input.keyboard.createCursorKeys();
if (cursors.left.isDown) this.player.x -= speed * 0.016;
if (cursors.right.isDown) this.player.x += speed * 0.016;
if (cursors.up.isDown) this.player.y -= speed * 0.016;
if (cursors.down.isDown) this.player.y += speed * 0.016;
}
</script>
</body>
</html>โ
Run it by opening index.html in your browser.
You'll see a little Phaser character that moves with your arrow keys.
๐จ Step 3: Adding Visuals and Interactivity
You can easily add sprites, backgrounds, and animations.
function preload() {
this.load.image('background', 'https://labs.phaser.io/assets/skies/space3.png');
this.load.image('star', 'https://labs.phaser.io/assets/sprites/star.png');
this.load.image('player', 'https://labs.phaser.io/assets/sprites/phaser-dude.png');
}
function create() {
this.add.image(400, 300, 'background');
this.player = this.physics.add.image(400, 300, 'player');
this.star = this.physics.add.image(200, 200, 'star');
this.physics.add.overlap(this.player, this.star, collectStar, null, this);
}
function collectStar(player, star) {
star.disableBody(true, true);
alert("You collected the star!");
}Now you've got a collectible item and a mini interaction!
โก Step 4: Adding Physics and Motion
Phaser includes several built-in physics engines. The most common one is Arcade Physics, perfect for simple collisions and gravity.
You can easily make your player fall or jump:
this.player.setCollideWorldBounds(true);
this.player.setBounce(0.2);
this.player.setGravityY(300);Combine that with input handling, and you can build a platformer in just a few lines.
๐ Step 5: Adding Sound and Score
Phaser also supports sound effects and music.
function preload() {
this.load.audio('ding', 'https://labs.phaser.io/assets/audio/SoundEffects/p-ping.mp3');
}
function collectStar(player, star) {
this.sound.play('ding');
star.disableBody(true, true);
}Add a score counter this.add.text() and update it every time you collect something.
๐ Step 6: Export and Share
Phaser games run natively in browsers โ no installation required. You can easily:
- Host it on GitHub Pages, Netlify, or Itch.io
- Embed it on your personal website
- Share the link directly with friends or players
Because it's HTML5-based, your game works on desktops, mobile devices, and even smart TVs.
๐งฉ What's Next?
Now that you've got the basics, here are some directions to level up:
- Add multiple levels/scenes with the Scene Manager
- Use tilemaps for platformers
- Add enemies, AI, or power-ups
- Try TypeScript with Phaser 3 for cleaner, modular code
You'll find hundreds of free examples in the Phaser Labs gallery.
๐ฎ Complete Phaser Game Code (HTML + JS)
Save this as index.html, open it in your browser โ and boom! Youโve got a running game.

Output of the Game
๐ง How It Works
- Phaser Config: Defines the canvas size, physics, and scene lifecycle (
preload,create,update). - Preload: Loads all game assets (images, spritesheets).
- Create: Builds the world (player, platforms, stars, bombs).
- Update: Runs continuously to handle movement and interactions.
- Collect & Collide: Player earns points by collecting stars; bombs end the game.
๐ก Try Customizing It
Here are fun tweaks you can experiment with:
- ๐จ Change the background image or colors
- ๐ Add background music with
this.sound.add() - ๐ Make new enemy types or power-ups
- ๐ฌ Add a start screen or โPlay Againโ button
๐น๏ธ Final Thoughts
Phaser makes game development approachable โ even for total beginners. It abstracts away the complex aspects of rendering and physics, allowing you to focus on creativity and gameplay.
Whether you're making a simple 2D clicker or your next indie hit, Phaser gives you all the tools to turn imagination into interaction โ right in your browser.
