The goal of Blackjack is to get a higher hand value than the dealer, but without going over 21. You may hit as many times as you like to add to your hand. For your first move, you may also choose to double, which doubles your bet and gives you exactly one more card. You can split your first two cards if they have the same value. If the dealer shows an ace, you can buy insurance against the dealer having a natural 21.
All number cards are worth their face value. Jacks, queens and kings are worth 10. An ace can be worth either 1 or 11. The dealer must hit until he has at least 17.
Before the cards are dealt, click on the chips to increase your bet. You can bet a minimum of $5 and a maximum of $25.
