Blackjack, in it’s simplest form is a card game comparing your hand to the dealers’. Blackjack's precursor was twenty-one, a game of unknown origin. When twenty-one was introduced in the United States, gambling houses offered bonus payouts to stimulate players' interest. One such bonus was a ten-to-one payout if the player's hand consisted of the ace of spades and a black jack (either the jack of clubs or the jack of spades). This later became the namesake for modern day 21
