Jokers Session

Joker is a special type of playing card found in most modern decks, or else a type of tile in some Mahjong game sets.
Name
It is believed that the term "Joker" comes from a mispronunciation of Jucker, the German/Alsatian name for the game Euchre. The card was originally introduced in about 1860 for games of that family to be used as the highest trump. Catherine Perry Hargrave documents jokers from 1862 and 1865 in her book A History of Playing Cards. The 1862 card has a tiger on it and the label "Highest Trump", while the one from 1865 is inscribed "This card takes either Bower" and "Imperial Bower", or "Highest Trump Card".
