When the dealer is getting lucky i.e. winning quite a lot of times, it might be a good idea to just stop and watch a couple turns. At most of the casinos, the cards when dealt are faced down to prevent any kind of cheating. The dealer always receives one card down and one card up.
The value of the cards are as follows:
All numbers except an Ace, Jack, Queen, and King are special cards. While all the numbers from 2 -10 represent their card number, numbers such as 10, J, Q, K are all equivalent to 10. An Ace could be used as 1 or 10. You can easily “hit” or “stay” by using the options on the computer screen.
The dealer has another important rule to obey: If it has numbers adding to less than 16, then he must take another card. If the number exceeds 17, he cannot hit again thus has to “stay”.
When a player gets a Blackjack with the first 2 cards, he is paid 150% of the original bet. So, for example, if someone bets $100, then he will be paid $150.
