Description of the judge.
Description of the judge.
There will be two different categories with top 10 games in every category.
You can submit your game to only one or both categories - it's up to you.
There will also be a Twitter, Facebook and Google+ Specials just like a year and two ago.
Full power of the hardware.
Mobile touch devices.
Package size below 13 kB
All your code and game assets should be smaller than or equal to 13 kilobytes (that's exactly 13,312 bytes, because of 13 x 1024) when zipped. Your package should contain index.html file and when unzipped should work in the browser.
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 (Desktop and Mobile categories, not applicable to Server) and all the game assets should fit in the package(s) 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.
Main theme - will be announced soon
The main theme of the competition will be announced on 13th August 2014.
Deadline - 13th September 2014
The competition starts at 13:00 CEST, 13th August 2014 and ends at 13:00 CEST, 13th September 2014. 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 in at least one browser. 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. You'll get extra points if your game supports any mobile devices.
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 will be 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.
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.
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 CoffeeScript or TypeScript?
- Can I use compression through the self-extracting PNGs?
