Free HTML5 Games with Source Code

1. HTML5 Delta

And that’s about it folks! I might revisit this prototype again in the future and add more variety to the alien patterns, along with power ups and boss aliens.

2. Tower Platformer

If you’ve been around long enough you might have played Nebulus on the c64 (I think it was called ‘Tower Toppler’ on other platforms). It pushed the limits of what the c64 could do graphically, but it was also a great game to play with challenging level design.

3. PixelDefense

PixelDefense is one of the most beautiful and perfectly designed examples of open source HTML5 and JavaScript games. It is based on the tower defense game genre. In this game you have to place the towers in the specified places to prevent the incoming monsters from entering your homeland. You will be pleased to hear that the source code of this outstanding game is freely available for download from the Github repository. It will be a great opportunity for you to understand the mechanics of online game development if you are familiar with the basics of HTML5 and JavaScript.

4. Clumsy Bird

Remember Flappy Bird? The game that took the app stores by storm and made everyone wonder how can such a simple yet hard to play game be so addictive? Well, now you can find the source code of its clone made in HTML5, using MelonJS and is named Clumsy Bird. This game is developed by Ellison Leão and he has made an easy customizing guide also available for his game, in case you get inspired to clone this clone.

5. Javascript Pseudo 3D Racer

This is an Outrun-style pseudo-3d racing game built in HTML5 and JavaScript by Jake Gordon and licensed with MIT license. He has written a tutorial about how he built this racing game. You can also read his other tutorials on JavaScript Pong as well as JavaScript Snakes games to learn about game development with JavaScript.
