Up Jenkins

Up Jenkins, also known by the shortened name Jenkins, is a party game in which players conceal a small coin (or ring, button, etc.) in their palm as they slap it on a table with their bare hands. The goal of the game is for the players on the team without the coin to correctly identify which hand the coin is under. The game typically consists of two two- to four-player teams, one on each side of a table. There are no official rules, so rules may vary widely, the game is often played with alcohol beverages with which to drink as a forfeit.
