card game popular in the United States, Canada, New Zealand, and Great Britain, especially in Cornwall and the West Country of England. It derives from a 19th-century Alsatian game called juckerspiel from the fact that its two top trumps are Jucker, meaning "jack." This word may also have influenced the choice of the term joker for the extra card introduced into American euchre in the 1860s to act as the "best bower," or topmost trump; bower is from German Bauer, literally "farmer" but also meaning "jack." Euchre is therefore the game for which the joker was invented-the joker being, in effect, a glorified jack
