Chemin de Fer is one of the more well-known games bet on in betting houses. Blackjack is also known as 21 or Chemin de Fer. The game is a mix of luck and ability coupled with choices. The game has evolved over a period of time. Players have specialized in specific abilities like "card counting," which allows them to turn the odds of the game in the players direction. The card game has been in existence since the 18th century. References can be seen in historical documents to a game referred to as "vingt-et-un," which in French means 21, and is thought of as the ancestor to black jack.

The game was initially not so popular in the united states of america. This led to the gambling houses attempting a number of features like offering a bonus in case of a ten to one payout, if the blackjack player was dealt a "black" jack and an ace of spades. The jack could be either the jack of clubs or jack of spades. After the game became well-known, the bonus pay out quickly disappeared from the rules.

Any hand which achieves a sum of 21 is considered a winner. The total can not be in excess of 21, if it does the hand is said to be "bust." The goal of every player is to defeat the croupier. If the blackjack player and the croupier both have the identical hand value, it’s called "push," with not either the player or the croupier winning the hand.
