Kings Cup will not be on this list. It sucks balls. Who wants to play a game where you might have to chug a tequila, zima, martini, and beer mixture? Yeah, I said it...Zima! remember that crap?
Honorable Mentions- Roxanne- One team takes "Red Light;" the other take "Roxanne." Drink every time your word comes up. I believe "Red Light" wins by one.
Never Have I Ever- As featured on "Lost." Say something you haven't done. Anyone who has done it drinks.
Asshole- A complicated card game that comes down to the politics of revenge.
Keg Stands- Who can be lifted upside down on top of a keg, while chugging through the hose the longest? Does this count as a game?
Up the River, Down the River- Everyone gets four cards. You drink or assign when the dealer shows a matching card depending upon where you are on "the River"
High/Low- Call Higher, Lower, or the color of the next card. Drink half the amount of cards played if you lose.
3 man- a fun drinking dice game
Easter Beer Hunt- Everyone buys a six pack of their choosing. The beers are hidden by friends. The first to finish their six pack wins.
Chutes and Ladders- Drink for every level of chute you go down. Assign for every level you climb a ladder. Every time you land on a multiple of 10, make a rule.
5. Century Club- 
Take a shot of beer every minute for 100 minutes. Insane? yes. Fun? Definitely.
4. Transformers the Movie-

The 80's movie. You know, the one for children? Take a drink every time anything transforms. Chug for the length of time Unicron transforms. This will take you back to your childhood. I promise.
3. Edward 40 hands- 
Duct tape to 40's of beer to your hands. You may not take them off until you finish both.
2. Beer Pong-
Look, I am not very good at this game. Which might be why I like it. Every time I play it, I get drunk.
1. Quarters- 
Basically, this is Tiddlywinks for adults. You take a quarter and bounce in into one of three shot glasses. If you make it in you get to assign that shot to a player of your choice. Played with beer.
