Blackjack (sometimes called Twenty-One) is a popular card game at casinos. An introduction to
the rules of the game can be found at the United States Play Card Company’s website:

In Blackjack, suits are not important. Each card is worth a certain number of points, and the goal
is to accumulate a point total which is higher than the dealer’s point total, without going over 21.
Most cards are worth the number of points printed on the card (for example, the Four of Clubs is
worth 4 points). However, Jacks, Queens and Kings are worth 10 points, and Aces are worth 1
point or 11 points (player’s choice).
