Cards Against Blockchain is a fork of Cards Against Cryptography, and based on Cards Against Humanity. Cards Against Humanity describes itself as "a party game for horrible people", and Cards Against Blockchain strives to be equally mean. If you don't like crude or offensive humor, this game may not be for you. We hope this game is played in a spirit of fun, and even played on-chain.
See RULES.md for the rules.

The top-level Makefile can be used to recompile printable PDF and PNG versions of the cards:
make PDFs PNGs
This should work on reasonable Linux or macOS systems. You need to have xelatex, python3, and ImageMagick's convert command in your path. One of the cards uses the Comic Sans font, so you need to have that on your system as well, possibly by installing the TeXLive packaging comicsans or installing it in your operating system's fonts folder.
You can build specific releases of the cards using environment variables, e.g.
make PDFs PNGs WHITE=white-ec19-expansion BLACK=black-ec19-expansion
Since Cards Against Humanity was released under a BY-NC-SA 2.0 license, the "non-commercial" aspect of that license implies that we cannot sell you a copy of this game. You can make your own printed copy in three ways.
- Print at home. Under the
PDFs-to-printfolder, there are printable PDFs of all the cards, formatted for 2-sided printing on either A4 or letter paper. You'll use up all the toner if print pages and pages of all-black backgrounds, so you should probably use the gray background. - Print at a local printshop. You could also take the PDFs to your local print shop and have them print it on cardstock (80-pound or higher). Use a paper cutter to cut out the cards.
- Print via a commercial custom card manufacturer. We printed our version of Cards Against Cryptography using MakePlayingCards.com. The folder
PNGs-to-printcontains the PNG images required to print a deck of cards at MakePlayingCards.com's US Game Deck Size, along with a bi-fold (4 side) instruction booklet. At the time we wrote this, 1 set of cards, along with a booklet and plain white box, is $34.35 (US dollars), plus shipping (approximately $10 for standard shipping to most countries). Uploading the images and configure the project takes about 10 minutes.
The first edition of Cards Against Cryptography was released at the rump session of Asiacrypt 2018. There was an expansion pack at the rump session of Eurocrypt 2019, and a special "work"-from-home virtual expansion pack at the virtual rump session of virtual Eurocrypt 2020.
