What Can You Find on the js13kGames Website?

Updated

js13kGames is a coding competition for web game developers, built around a hallmark 13KB size limit. The website at js13kgames.com is the competition's main hub: it's where you can browse and play past entries, read announcements and rules, and find out how to take part in the current edition.

Past competition entries you can browse and play

The core of the site is its archive of submitted games. Because every entry has to fit inside 13KB, the collection is a showcase of what developers can do with a tiny budget of code, art, and audio.

  • Games are organized by edition, so you can look through a specific year's theme and submissions.
  • Entries are typically playable directly in the browser, since they're built with web technologies.
  • You can use the archive to see how different developers approached the same constraint and theme.

If you're evaluating whether the competition is worth your time, playing a handful of past entries is the fastest way to understand the expected scope and polish.

Competition information and announcements

Beyond the games themselves, the site carries the practical details of the event:

  • The current year's edition and its theme.
  • Rules and the 13KB size limit that defines every submission.
  • Announcements, results, and news about the competition.

This makes js13kgames.com the primary entry point for anyone who wants to follow or join the competition, rather than relying on secondhand summaries.

  2. Browse the games archive by edition to play entries in your browser.
