Flip Cups: a Drinking Game
Players: 6 and up
Materials: Beer, and one cheap plastic cup per person.
Here's a quick, fun game. The rules are as follows. Players line up in two rows on either side of a table. Each has his cup in front of him; it is ~1/3 full.
Starting at one end, both players at the same time pick up their cups and drink them as fast as possible. Then, when the cups are empty, they are placed right-side-up on the edge of the table. The players then attempt to flip their cups by hitting the bottoms, until the cups land on the table upside-down. When this is accomplished, the next player in line may go.
First team to flip all their cups wins.
