The object of the game is to get the hand as close to a value of 9 as possible. Aces are worth 1, face cards and 10s are worth 0 and all other cards are worth the points indicated on the card.
In the European version, players bet on either the hand-holder or the dealer to win the hand. In the American version, players are betting on themselves to win. Dealer and player each get two concealed cards and have the option to take a third card.
While there is some choice on taking a card or not in the European version, the American version has a set sequence of events and the player's play is basically predetermined, making it a game of luck.
