At the start, it is customary for the initiating players to make a toast, after which the first member of each team drinks the entirety of their beverage. When finished, the cup is placed open side up at the edge of the table, and the player who drank it attempts to flip the cup, by flicking or lifting the bottom of the cup until it flips and lands face down on the table, If a cup is knocked over in the chain whilst moving to the next cup the player must go back and re-flip. The player may not use two hands, or blow on the cup to guide it to flip over. If the player is unsuccessful on the first try, the cup is reset and re-flipped. Only after the first teammate is done flipping successfully can the next person proceed. Additionally, subsequent players may not touch or manipulate their cup until the previous player has successfully flipped their cup. Whichever team finishes drinking and flipping all its cups first wins.
Batavia Downs flip cup varies slightly from the original version. Batavia Downs flip cup takes place around a circular table and requires a minimum of four players. Two players standing opposite of each other, start at the same time. As each player successfully drinks from and flips their cup the next person to their right (counter clockwise) goes. In addition, after each successful flip, players must refill their cup in the event that the player standing directly left of them successfully lands their cup. The game continues as a circular race until a player is unable to successfully flip their cup, before the person directly to their left flips theirs.
The game starts exactly the same as the original version but once a team loses a round they must vote off one member of their team. That team is still responsible for drinking the same number of cups as their opponents in the next round and thus must designate a player to flip more than one cup. A team wins when their opponents have no remaining players to vote off.
