h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

All the players should sit in a circle. The basic idea is to go round the circle, counting upwards from 1. Th eloser is teh person who says '21'.

To start, the first player says 'To my left (or right, depending what direction they want to go in), one'
The player on their left then says '2', and so on.

However, if a player says two consecutive numbers, ie '3, 4' the direction is reversed. If a player says *three* consecutive numbers, play continues in the same direction, but skips a player. So a typical four-player game might go:

Player 1: 'To my right, 1'
Player 4: '2, 3'
Player 1: '4, 5, 6'
Player 3: ''7, 8'
Player 2: '9'
Player 1: '10'

and so on, if the players were numbered in a clockwise direction.

If (or when!) someone makes a mistake - speaking at the wrong time, hesitating, or saying the wrong thing, the game starts over. The player who fouled up should get a forfeit of some kind. The player who last said a number (correctly) should re-start the game at 1.

When you finally get to 21, the player to say 21 gets a forfeit - usually a drinking penalty. They also make up a new 'rule' - which replaces one of the numbers. For example, 7 could become 'fish', in which case the sequence would be '...5, 6, fish, 8, ...' or it could become an action - like 'touch the floor' or 'run to the bar and back'.

The game ends when everyone is well and truly or fed up with it.

I have tried a variant of this game.
The idea is to pretend you are driving a car.
"Wrom" is the standart sound that just keeps the game going.
"dyyt" (The sound of a horn) = skip a person
"Eeeeh" (Sound of sudden breaking)= change direction
Then there is the acident:
One person says "crach", the next says "bang", the third "babu" and the fourth "babu" (Ambulance sound). During this it is not possible to change direction or skip anybody. Whenever anybody makes a mistake he or she is out of the game and the last person to do it right starts the game off again.
The last person left is the winner.

For the car driving one, there are also actions! For 'Vroom', you move your hand from left to right (or vice versa, depending on which direction the 'car' is going), the horn you have to pretend is an old fashioned rubber bulbed type, which you are squeezing, and barking you have to hold on to the steering wheel as if braking hard.

There are many other variations, which i can't remember at present.
