Blackjack

Blackjack is a very popular game that probably originated in 16th Century France as vingt-et-un (20 and 1), hence its other name "21". It gained the English name Blackjack since a player who held the Ace of Spades (i.e. a Black spade) and the Jack of Spades as the first two cards would be paid out extra, and the gambler\'s penchant for easy rhymes took over (think "chuck-a-luck", "acey-duecy")
