I love the first game! It's easy to play, and you probably have all the tools you need at home already. 

Monday: "Christmas Cards"

Needed: 2+ people, deck of cards, beer

Instructions: Place the cards face down like a Christmas tree with five rows (one card up top, two in the second row, three in the third, and so on) with one card at the bottom placed sideways that acts as the stump. Start at the stump and flip the card over. If it's red, you take the amount of drinks the card represents and if it's black you give the drinks out. 10 is waterfall, J is "never have I ever," Q is "questions" and Ace is a male rule. However if a K is drawn, it's a shotgun/chug. Drink until all the cards in the tree are flipped over or until you use the actual Christmas tree stand as a urinal.

Thanks to COED for all these games. There are 8 more HERE.
