Fill the Pumpkin
A card game filled with thrills and chills? Yes, please! For this game, make sure you have a plastic pumpkin (or any other container) that doesn't leak. Spread out a deck of cards face down, and assign different rules to each card.
For example, each time someone draws a "king," that person must take a sip of their drink. Or each time a person draws a "queen," they can make someone else drink. The rules are up to you to decide, so have fun and be creative! Just remember to assign certain cards to be the cue for people to pour shot-size portions of their drinks into the pumpkin (or container.)
Finally, when someone draws the "ace," they have to drink whatever is in the pumpkin. As you can probably imagine, this game works best when everyone is drinking different kinds of beverages.
