In Blackjack, the objective is to try to beat the dealer by getting closer to 21. If the total value of your hand is closer to 21 than the dealer's hand, you win an equal amount to what you have bet. If you have a blackjack hand, you win 3:2 times your bet (example - a $5 bet will win $7.50), as long as the dealer does not also have blackjack. Aces have a value of either 1 or 11, face cards as 10 and the cards that are left are valued as their face numbers. Because you can play an Ace either way, a hand with an ace is called a soft hand.
If the total of your hand is over 21, you'll bust and lose your bet. If you have the same card total as the dealer, from 17 and up, you get your bet back in a push as neither have won. Blackjack beats a count of 21.
The dealer must draw cards until they have at least 17 and must stand at 17 or higher.
