If at any point, the total value exceeds 21, you get busted, and you’re out of that round.If needed you can also ask for one additional card at a time in order to reach as close to 21 as possible. You win if the value is less than 21 but higher than the dealer's score.So, a 5 card has 5 points, a 6 card has 6 points, and so on. The numbered cards have a value equal to their numbers irrespective of the suit.Every table has seven boxes and the cards are dealt from a shoe containing six pre-shuffled decks.Blackjack is a game of cards played against the dealer or the house.
