JS13KGAMES – A JavaScript Coding Competition

August 2nd, 2016 | By Jscrambler | 2 min read

Jscrambler will sponsor Js13kGames, a JavaScript coding competition for HTML5 Game Developers.

The fun part of the compo is the file size limit set to 13 kilobytes. The competition will start at 13:00 CEST, on 13th August and will end at 13:00 CEST, on 13th September 2016. The theme will be announced on 13th August. Save the date!

The Js13kGames is a competition where developers are limited to a maximum game size of 13 kilobytes, including all assets like images and sounds. The challenge in this competition is to make the coolest game in only 13 kilobytes. You have exactly one month to work on your game, and win the cool prizes and the admiration of your peers!

All the source codes have to be hosted open source on GitHub, so other developers can learn from your coding skills. You will have to provide both the compressed and the uncompressed versions of the game source files. External libraries are not allowed which means that your game should be able to run offline without the need of loading any external resources. It should also be kept in mind that only pure JavaScript code can be submitted.

There are 3 different categories and they are desktop, mobile, and server. You can submit your game in any of these categories to be part of the competition.


All the participating HTML5 games will be reviewed by experienced people in the HTML5 game industry and JavaScript development. Among the major renowned personalities are Andrzej Mazur, Christer Kaitila, Jupiter Hadley, Pablo Farías Navarro, Robert Podgórski, Jason Weathersby, Elle Chen, and of course our CTO Pedro Fortuna, who has been participating as a judge since last year’s edition.

How can I know if I won?

Judges will review and vote for the games after September 13th and the winners will be announced on September 28th.

How can I join?
