A variation of quarters.
Required are 5-6 shot glasses(or more for more players-you will need one glass more than the number of players), Beer of choice, Hard liquor of choice and a quarter.
The rules(other than the normal rules). One glass filled with liquor in the middle- the rest filled with beer forming a circle around the center glass.
Play quarters as usual- if the shooter gets the quarter into any glass of beer he/she chooses the drinker.
If the shooter gets the quarter in the center liquor glass- all players must down their beer as quickly as possible. Whomever's glass is last to the table must also shoot the liquor glass.
