The Rules of Pivit
Here's a visual guide showing how to play Pivit. It's a one-page document that explains the complete rules in 63 words and several pictures.
I think there's something nice about a game this easy to learn. Of course, that's not a guarantee of being fun - so I'm working on a print-to-play version. This will let motivated kickstarters see for themselves what it's like to play Pivit.
Here's a link to the PDF version, which is much more readable than the image below. (Downloading the PDF looks better than in-browser viewing; some browsers don't render the images well.)
That PDF includes a one-page written version of the rules as well, for clarity.
