Black or Red
Black or Red is an American card game, often played as a drinking game.
In its most basic form it is one of the least complicated of drinking games. Gameplay requires a standard 52-card deck and may be played with any number of participants, to include a single player.
Traditionally each player takes a turn in order, drawing a single card from the top of the deck. Before looking at the card, they must call either "Black" or "Red" indicating their guess as to the color of the card. If they guess correctly their turn is completed and the next player draws. If they guess incorrectly they must drink a specified type and volume of alcohol before their turn is over.
The game may be considered to be finished when the deck is exhausted, or it may proceed indefinitely with cards being recycled back into the deck until a player has played enough.
Score tracking may be done, but is not required.
Some variants include additional rules, such as allowing players who successfully guess a color to select which player will draw next, that players who guess correctly a specified number of consecutive times may enact rules such as "may not guess black", "player must drink from the opposite side of their glass", etc., or that if a player guesses wrongly they must drink the number of sips shown on the card, while if they guess correctly they may distribute that number of sips to other players.[1][2][3][4][5]
