Drinking games are games which involve the consumption of alcoholic beverages. Evidence of the existence of drinking games dates back to antiquity. Drinking games have been banned at some institutions, particularly colleges and universities.
Kottabos is one of the earliest known drinking games from ancient Greece, dated to the 5th to 4th centuries BC. Players would use dregs to hit targets across the room with their wine. Often, there were special prizes and penalties for one's performance in the game.
Drinking games were enjoyed in ancient China, usually incorporating the use of dice or verbal exchange of riddles. During the Tang Dynasty (618-907), the Chinese used a silver canister where written lots could be drawn that designated which player had to drink and specifically how much; for example, from 1, 5, 7, or 10 measures of drink that the youngest player, or the last player to join the game, or the most talkative player, or the host, or the player with the greatest alcohol tolerance, etc. had to drink. There were even drinking game referee officials, including a 'registrar of the rules' who knew all the rules to the game, a 'registrar of the horn' who tossed a silver flag down on calling out second offenses, and a 'governor' who decided one's third call of offense. These referees were used mainly for maintaining order (as drinking games often became rowdy) and for reviewing faults that could be punished with a player drinking a penalty cup. If a guest was considered a 'coward' for dropping out of the game, he could be branded as a 'deserter' and not invited back to further drinking bouts. There was another game where little puppets and dolls dressed as western foreigners with blue eyes (Iranian peoples) were set up and when one fell over, the person it pointed to had to empty his cup of wine.
The simplest drinking games are endurance games in which players compete to out-drink one another. Players take turns taking shots, and the last person standing is the winner. Some games have rules involving the "cascade", "fountain" or "waterfall", which encourages each player to drink constantly from their cup so long as the player before him does not stop drinking. Such games can also favor speed over quantity, in which players race to drink a case of beer the fastest. Often drinking large amounts will be combined with a stylistic element or an abnormal method of drinking, as with the boot of beer, yard of ale or a keg stand.
