Sure, there are drinking rules for these games out there but none are as hardcore as my group of friends rules we've been using for the better part of a decade and refined over that period of time. Last year I decided to make a large gloss poster for the living room but I figured I'd share our written out rules with the masses too! I lost my higher quality project file in a hard drive crash but I salvaged a Imgur link I had.

Usually we play with the older games 1-4 and have 2 games going at the same time. I'm not sure how balanced these rules are with the newer games but I'd imagine its fine up to 8. I'd say drink responsibly, but I think I'd be lying with this set of rules. Have fun! 20 turns is plenty, we have done a 40 turn round and well most of us don't remember much of that night so uh, I'm going to recommend keeping it short.
