How to Play
It is ludicrously simple. When the referee calls start, all players must start drinking a full pint of beer. The first person to finish indicates they have done by placing the inverted glass on their head. First one to neck the pint wins. Anyone with beer left in their glass when the first person finished, must pour it over their heads.
If someone inverts their glass before they finish, they must consume another beer until they get it right.
