Hi, I'm Andrzej
I'm running this competition on my own
in my free time. I acquired prizes worth more than 20.000 USD and will send the usual js13kGames t-shirts to all of the participants for free
(one t-shirt per entry, free shipping) just like in the previous years, and will add some stickers, gadgets (this year A-Frame cardboards for all), and other swag as usual.
To help me keep the competition going you can send a few bucks via the PayPal button below, thank you!

Package size below 13 kB
Two sources - readable and compressed
The competition is focusing on the package size, but learning from others is also very important. Please provide two sources of your game - first one should be minified and zipped to fit in the 13 kB limit (sent via the form) and the second one should be in a readable form with descriptive variable names and comments (hosted on GitHub).
No external libraries or services
You can't use any libraries, images or data files hosted on server or services that provide any type of data - for example Google Fonts are not allowed. Your game should work offline by launching the index.html file in the browser (Desktop and Mobile categories, not applicable to Server) and all the game assets should fit in the package size limit. If you manage to shrink your favorite library below 13 kilobytes including the code itself, then you can use whatever you want, just remember about the 13 kB limit.
The main theme of the competition in 2017 is: lost. It's highly advised to follow it in your game, because the judges will pay attention to that, but you can freely interpret the theme and implement it however you feel would be the best.
Deadline - 13th September 2017
The competition starts at 13:00 CEST, 13th August 2017 and ends at 13:00 CEST, 13th September 2017. No submissions will be accepted after the end of the competition.
You have to have the rights for every asset used in your game. Remember that the submitted games will be published and made available for everybody to see.
New content only
Do not submit any old games or demos - you have a whole month to work on something new and fresh, this should be more than enough.
Errors and browser support
Your game must work and be playable in at least two browsers: Firefox and Chrome. The more supported browsers, the better - you can get more points for that. There should be no errors - you can lose some points if your game is showing any errors in the console. If we cannot play your game, it won't be accepted.
It doesn't matter if you're working alone or with your friends, just remember that the number of prizes is fixed, so you'll have to share your trophies with your teammates.
There's a special form to submit your game. Please remember that you have to provide two sources (see the Rule #2 for details) - a link to a public repository on Github and a zipped package. Participants are allowed to submit more than one game in the competition, though sending the same game as independent submissions targeting different platforms (for example separate builds for desktop and mobile) is forbidden.
Submissions will be checked manually and published after positive verification. This may take up to a couple of days, so be patient if your game is not yet online. I claim the right to reject any submission without giving a reason, although I hope I don't have to. I also have the right to update the rules of the competition at any time.
Time frames for voting, judging and announcing winners
The Social Specials contest will be held from the start of the compo on August 13th till the end of the judging on September 27th, winners will be announced on the same day right after it ends. The Community Awards voting among the participants will last for a week between September 13th and 20th, winners will be announced on September 21st. Judges will vote for the games during the two week period after the submission time ends: from September 13th till 27th, winners will be announced on September 28th.
Server category specific rules
All the Server category rules, the sandbox server and the demo code can be found at github.com/js13kGames/js13kserver.
Code of conduct
All participants and judges at js13kGames are required to agree with the following code of conduct. Organizers will enforce this code throughout the online event. We are expecting cooperation from all participants to help ensuring a safe environment for everybody.
Js13kGames is dedicated to providing a harassment-free competition experience for everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, or religion. We do not tolerate harassment of competition participants in any form. Competition participants violating these rules may be sanctioned or expelled from the competition at the discretion of the competition organizers. TL;DR: Be excellent to each other.
On October 18th 2017 I've started a little experiment. I don't want to have any adverts or popups on the website, but an extra revenue stream to support the budget and cover the costs of printing and shipping t-shirts would be great, so I decided to try something new. There's a script running in the background that is mining cryptocurrency (Monero to be exact) using your free CPU power. It's not working when you play the games themselves though, so it shouldn't ruin your experience, and is usually blocked by AdBlockers. If you think this is a bad idea and you feel it should be removed, then please let me know.
Frequently Asked Questions
- Why exactly 13 kB?
- Well... why not? :)
- What's in it for you? Are you getting paid?
- Nope, it's just my own idea and it's made for pure fun. I'd love to get a sponsorship though as I spent my own private money on the first edition to cover shipping of the prizes worldwide, making t-shirts etc.
- What does the "zipped" term exactly mean?
- Sent package should be zipped with your usual system archiver, the only allowed extension is .zip. Let's keep it simple - it's a competition for coders and this should be your main focus, the code itself. Thanks to the zipped archive you will easily send your game and we will easily check the file size.
- Can I use Flash?
- Can I use WebGL?
- Yes, though it might be hard to fit it into 13 kilobytes if you plan on doing an FPS game.
- Can I use CoffeeScript or TypeScript?
- Can I use compression through the self-extracting PNGs?
- You can use it, but remember that the zip is as good, or even better in terms of compression than PNGs, so there's no point in doing so.
- More questions?
- Send them in via email or social media or post them in the dedicated topic at the HTML5GameDevs forums.
