Euchre or eucre is a trick-taking card game most commonly played with four people in two partnerships with a deck of 24, or sometimes 32, standard playing cards. It is the game responsible for introducing the joker into modern packs; this was invented around 1860 to act as a top trump or best bower (from the German word Bauer, "farmer", denoting also the jack). It is believed to be closely related to the French game Écarté that was popularized in the United States by the Cornish and Pennsylvania Dutch, and to the seventeenth-century game of bad repute Loo. It may be sometimes referred to as Knock Euchre to distinguish it from Bid Euchre.
