Cards Against Humanity is a fun, crass fill-in-the-blank party game, played using a set of question cards and answer cards. (You can get an idea for the game here, but be warned it’s largely NSFW.) You can print out the game yourself (it’s available for free online), or order professionally made card packs from the creators. These are probably the nicest way to play, but they also cost quite a bit?—?about £100 for the base game and all the major expansions. Playing with tree carcasses is so last century, so let’s look at some cheaper and more convenient high tech alternatives.
