Being able to win at Blackjack takes a combination of skill, strategy, and luck.  Naturally, thereís no way for you to know which hand youíll be dealt, but if you set up your own personal strategy and stick to it, youíll find that your luck plays more in your favor than if you play randomly.  Remember that your goal is always to get as close to 21 without going over.  If youíre only playing against the dealer, itís always best to know the dealerís betting rules so that you can take that into account for your own strategy.

One of the older card games that is still enjoyed today is called Whist.  If you are a card player, the odds are that you have played Whist in at least one of its forms at some point in your life.  These forms come and go, but some of the types that have withstood the test of time are Call Ace Whist (a version most popular in Denmark), as well as Minnesota Whist (which hasnít any trump cards), German Whist (which involves only two players), and even Hokm (a version from Iran).  Typically speaking, Whist requires two teams of two ñ that is, four players.

Though bridge is its own card game, it finds its roots as a derivative of another popular card game called Whist.  Bridge was developed back in the 1890ís and exploded in popularity throughout Great Britain and the United States.  The gameís development was heavily impacted by Harold Stirling Vanderbilt, who was not only an avid player of the game, but also helped to solidify its rules and bring it into the form of the game that we recognize today. By 1925, the gameís rules were as they are today, and the number of players were on a quick rise.
