Where can I purchase a physical copy?

Talks are ongoing with several major UK retailers. For now, the PDF version is free to download from the Home page—or see the Try page for a web implementation.

What are the rules?

You are free to do (or indeed not do) whatever you please, at any given moment. As such, the prescription of rules felt superfluous.

Can I play along without drinking?

See the previous answer.

Why create a "drinking game"?

I felt that I had exhausted PowerPoint as a storytelling medium.

Are any expansion packs available?

The first expansion pack of 20 cards was created recently, and is included in the web implementation. More packs might follow sporadically over the next year or so.
