Surprised no-one’s mentioned Twenty-Ones yet, but maybe it’s only common in the UK. Anyway, someone starts the game by saying: “I propose a gentleman’s game of twenty-ones, one to my left.” The person to the left then says “Two”, the next person “Three”, etc. However, you may say up to three numbers in a row. So, continuing, “Four” would continue to pass to the left, “Five, six” would reverse the direction so the person to the right says “Seven”. The person to the right of them may then say “Eight, nine, ten”, which would skip the next person. You may not say more than three numbers. The person who is forced to say “Twenty-one” must drink, and can then invent a new rule, e.g. no pointing, no saying the word “drink”, or they can substitute a certain number for a phrase, e.g. “Two” is now “1920s style death ray” so the play now runs: “One, 1920s style death ray, three” etc. It’s harder than it sounds and great fun!
RE: power hour and century club. The best way to do this is to burn a music CD. Just cut each song down to one minute. Everytime the song changes, you take your shot-o-beer. Works much better than a person and a second hand.
My favorites:
Fuzzy Duck - Everyone sits in a circle. One person starts by saying either “fuzzy duck” or “ducky fuzz”. If he says “fuzzy duck”, the person to the right has to repeat “fuzzy duck”. If he says “ducky fuzz”, the person to the left has to repeat “ducky fuzz”. This continues around the table until someone says “does he?”. The direction reverses and the other phrase has to be used. If anyone says something other than “fuzzy duck”, “ducky fuzz” or “does he?”. They have to drink. The reason that this is so much fun, especially with someone who gets embarrassed if they swear, is that after the reverse, people usually say “does he fuck” or “fuck he does”. Hilarity ensues.
Chinese drinking game from the movie “Shangi Noon”. Esentially, the premise of this game is for the two people to each hold out between one and four fingers on one hand. Then both people, at the same time, say (sum of the two sets of fingers) and (sum of the two sets of fingers), who should drink. It would be something like 4 and 4 who should drink. This gets repeated at a fast pace until someone screws up the addition or just says nothing. That person drinks. If you start losing early, you get drunk, which makes the game tougher which means you lose, which means you get drunk…
Oh, I got one more that we used to play with a bartender at my local college bar.
7-14-21:
You start with a cup and 5 dice. The first person rolls and counts the number of ones that they roll. Say you roll 3 1 4 1 5, you would say one, two and roll again. Next time you get 1 4 3 2 6. You would say three and roll again until you roll no ones. Then you pass the dice and the next person rolls and continues counting where you left off.
The person that rolls the 7th one picks the shot, the person that rolls the 14th one buys the shot, the person that rolls the 21st one takes the shot. But there are rules that make it tricky.
If you put the dice in the cup and pass them to the next person, that’s loaded die.
If your roll goes off the bar/table that’s sloppy die.
If you roll the dice and one is on top of another one, you re-roll. If that happens three times in a row, that’s cocked die.
Anyone one of these results in a penalty shot which was free where we played, but it was the cheapest, nastiest liqueur known to man(at least this man).
One last part to this game. After 16, you have the potential for taking multiple shots. If you are “lookin for 17” and you roll 5 ones, you take 5 shots. If you roll 1 one, that die is removed and you roll again. Now you have the potential to take four shots if four ones are rolled. Usually all but the last die is removed and the 21st one is by itself, but I have see double quite abit and have even recieved a triple shot from rolling the last three ones at the same time.
This probably isn’t making much sense, you just have to play it. Let me know if you need clarification.
Lastly, my favorite drinking game ever is the “Gentleman’s Game of Croquet.”
Here are the rules:
The Rules:
The rules marked with * considered a minor violation if not followed.
Those marked with ** are a major violation.
Minor voilations are punished by the offender taking one drink of
beverage and the offender's ball being repositioned with an underhand
loft.
An under hand loft is performed by the person who witnessed the
offense and can only move his/her forearm and hand while lofting. No
movement can
be made above the elbow.
Major voilations are punished by the offender finishing their current
beverage and the offender's ball being repositioned with an overhand
loft.
An overhand loft very much resembles the long arm throw of a
baseball
outfielder. The distance and verocity of the loft is proportional to
the degree of the offence and is up to the discretion of the witness.
At the beginning of a game all members must decide if they will slam a drink for each wicket successfully passed through or will they just take a drink.
A persons ball may also be lofted through a wicket if it is determined (by a vote) that said person is not trying for fear of having to slam another drink.
Rules can be made up on the fly. Simply suggest a rule and have a vote. (Majority rules) Also a dumb idea can also be cause for a loft.
The only time a person’s turn may be skipped is if they left the field of play and do not return after a determined length of time (Usually the rest of the players count down from ten)
Croquet can be played at night or and indoors.
* Use of proper names only. No nicknames or shortened versions of
names shall be used. Only the full first name as seen on the person's
birth certificate may be used. The person can be addressed using that
person's last name if it is immediately preceded by a proper title
(Mr., Duke, Lord, ...)
* The proper term for the ball hitting device is "mallet". The
proper pronunciation is mal-ey.
* No use of golf terms.
* No unnecessary yelling. (This is a gentleman's game). One may only
use a raised voice if it is necessary to communicate with someone
who's ball has been lofted.
** No going out of turn. The order has to be set at the beginning of
the game and can not change.
** No swearing. Anything that you would not say to your parents at
the age of 6 is considered swearing.
If you swore at your parents at the age of 6, you are ineligible for
this game.
** Under no circumstances shall your drink (except to refill or
replace with a full one) or mallet leave your hand. These are both
vital tools for the games and cannot be abandoned.
* No destruction of the course. Knocking over wickets is a common
example of breaking this rule.
Anything that is disturbed during the course of one's turn must be
returned to it's original condition as much as possible.
-**Dangerous Play - If you are hitting your ball towards players or
spectators, you need to yell “two” to warn them of the incoming ball.
If you do not yell two and you hit somebody, its an overhand loft. If
you do yell two, and hit a player, their ball is to be lofted. “Two”
has to be yelled loud enough for all to hear. Hitting vehicles or other
spendy objects is also an overhand loft.
-Defense(not a violation) - If another player is getting into position
to “send” your ball, or in the act of “sending” said ball, you may use
your mallet to rub them in any area of their body to try and make them
miss, thus, playing defense. I recommend the crotchal region from
behind.
-*Trying - The Gentleman’s Game of Croquet is meant to be a long game.
If you feel that another player is trying to hard to finish the course,
their ball may be lofted at any time to slow them down. This loft will
be at the discretion of the rest of the group, not including the loftee.
-When playing near a street with storm drains, it is acceptable to use
another player as a gutter guard(to keep your ball from going down the
drain)when somebody is lofting your ball down the street.
-There is no “out-of-bounds”. Even if the neighbors say you cannot use
their lawn, they have to understand that this is CROQUET.
-“Helper Loft” - The helper loft is used in the rare occasion that a
player hits a great shot through a wicket. The “helper loft” is an
underhand or overhand loft, lofted by the person who deemed the shot
great, that places the player’s ball closer to the next wicket.
-“Killer Ball” - When and if you go down and back through the wickets,
your ball is deemed a “killer ball” and any ball that your ball touches
from then on is out of the competition.
-To truly win a game of Croquet, you have to kill everybody else’s ball.
We did this when we made a drinking game out of “Trivial Pursuit”. You took a drink every time you got an answer right, and when you got a pie wedge you got to make a rule. Yes, the drinking does start to pile up as there are more rules to remember. I don’t think I have ever seen my sister more shit-faced than that night.
There was another one we played in college, where you would get about a half dozen or so people in a circle and everyone had their own personal hand gesture. Then to start the game someone would clap make their gesture then make someone else’s gesture. That person would then have to make their gesture, then make someone else’s gesture. If someone didn’t recognize their gesture, or couldn’t think of someone else’s gesture fast enough after theirs, then they had to drink. I think maybe there was some clapping involved too to help keep a rhythm to the game but I forget exactly how it went. (That was twenty years ago!)
We simplified. We played a game called “You drink.” One person starts, points at another and declares, “You drink!”, then that person drinks and points at another person and declares, “You drink!”.
I don’t think I ever won that game. I don’t think anyone ever won.
We usually played this because we had misplaced the dice and cards.
OK I played Zoom -Shwartz-Pafigliano", “Quarters” and “Mexican”. A coupleo fothers.
Quarters Chasers: Usually played with 5-8 people. You have two quarters and each person has a cup/glass in front of them, all touching, and there is a larger, slightly taller one in the middle with beer in it. The two quarters start at opposite sides of the circle of people and you try and to make it in. When you finally do you pass it to your right. If you end up with both wuarters you lose and have to chug the beer in the middle. If you bounce it into the beer in the middle you have to chug that beer. If you make it in someone else’s glass you have to drink from your own beer before you can continue trying to make your quarter.
Sink the Bismark: You have a pitcher of beer and you float a cup in it about halfway filled with beer. People take turns pouring their beer into the cup until finally someone fills it up to the point where it sinks. At first folks pour fairly liberally, but ten it gets to a point where folks are trying to just put a drop in, not easy. The loser fishes it out and drink the whole beer. Not very hygenic to say the least.
Less of a game, more of a general atmosphere - the Intenational Rules of Drinking !
- Saying the words “drink” “drunk” or any deriative of those words means you must drink.
- If you point at someone or something, you must drink.
- If you swear, you drink.
- You may only drink with the hand that is not your dominant one.
There’s other stuff too that we added sometimes. It’s surprisingly hard to keep track of, especially if you’re also playing some other game. A friend of mine is terrible at it;
Us: Hey, which one is (name of a person present)
Friend: Uh, him points
Us: You pointed!
Friend: Oh, fuck. drinks with her dominant hand. Fuck, I have to drink again.
It’s entirely possible to get her stuck on a loop of penalty drinks. Very fun to watch. 
Very interesting that there are three posts about drinking games in a row by somone with the SDMB handle of, Brewha!
