You will need 4 or more players and a quarter to play.

Any person may begin the game. So, spin the quarter with your finger and before it stops spinning slap it down on the table with your hand making sure the quarter is not visible then you can call on any player you wish to guess if it is a bird or man (bird- tails, man -heads) if the person guesses right, it is now his or her turn to spin the quarter and you must take a chug. If the person guesses wrong, they must chug and you continue spinning the quarter until someone guesses correctly.
