the QR Code JavaScript Jam is a Game Jam where you should upload a game that is written in JavaScript (Use any libraries that you want) and fits into a QR code.

You are allowed to compress your code using any tool, but obviously, you'll need to incorporate resources into the JS file itself, because QR codes can only encode one file.

Also, it's not necessary to make a game in this jam, as you can also make a Fantasy Console, from example, for the js1k 2016 competition, someone uploaded the Marmorodde-1K, which is inspired from Comodorre systems, and the code is also compressed, to make it fit into 1K, but QR codes can hold even more than 1K, because they can hold a bit more than 2,8 KB. Yeah, Almost three times the size of the Marmorodde-1K!

Fortunately there's an exception to the rule that it need to fit in one QR code, because you can split the game/fantasy console into multiple QR codes, as long as the total capacity of the QR codes combined is maximum 2,8 KB.
