The gameboard is a plastic sheet covered with large colored circles, which is spread out on the floor. Any number of people can play, though more than 3-4 is a tight fit.
The game has one spinner, divided into fourths by color; each quadrant specifies left foot, right foot, left arm, or right arm. After spinning, the combination is called; players must move the part to a matching location. No two people can have a part on the same circle (rules are different for more people). Due to the scarcity of colored circles, players will often be required to put themselves in unlikely or precarious positions, eventually resulting in someone's fall.
Because of the high-paced and frivolous nature of the game, the close proximity it causes the participants to be to each other and the ease with which the frequent losses can be given forfeits (such as stripping or drinking - the latter leads to a vicious circle) make it highly popular at college parties.
