1 deck of cards
Arrange all cards in concentric circles face down. The object is to guess the proper suit of the card which will be turned over. Begin on the outer circle.
1. The first player will call 'red' or 'black', and;
a) if correct, the other player must drink the number on the card.
b) if incorrect, the flipper drinks that many drinks.
2. This continues until the circle is finished, but every time you reach the end of a circle, the number of drinks are doubled for the interior circles.
