Blackjack, also known as Twenty-one is a comparing-type card game which is the most widely played casino banking game in the world. The standard game is played with one or more decks of 52 cards. The basic rules of the game involve adding the value of an initial two card hand in hopes of approaching, but not exceeding, twenty-one. The game is played in many variations at casinos with different table rules. Much of blackjack’s popularity is due to the mix of chance and skill.
