Separate into two teams of 4 players each. Each player should have half a glass of beer. The large glass should be full in the middle of the table. The game starts with one player from each team chugging his/her beer. Upon consumption of that beer, the player will place the cup(rim down) on the edge of the table and attempt to flip it until it lands rim down on the table. Then the next player repeats. Once all players on a team have flipped their cups the other team must finish their beers and drink the center large cup.
