The game is available at nearly all online casinos.
Blackjack's low house edge and acceptable variance make it an excellent choice for playing through bonuses when allowed.
Blackjack hands are scored according to the sum of card values.
For example, a hand composed of a 4, 5, and 6 is scored as 4 5 6=15. Aces can be valued as either 1 or 11, so an ace and 7 could be scored as either a 8 or a 18.
The objective in blackjack is to have the highest card sum that does not exceed 21. If the player busts, he loses his bet, regardless of the dealer hand.
A 2-card 21 is known as a "blackjack" and is the highest ranking hand.
The player receives a bonus for having a blackjack. After placing a bet, the player and dealer are each given two cards.
One of the dealer's two cards is face up and visible to the player.
Under standard rules, if the dealer has an ace or 10-point card showing, he will peek for a possible blackjack.
If the dealer has an ace showing, the player has the opportunity to buy "insurance" against the blackjack.
Insurance pays 2:1 if the dealer's remaining card is a 10 or face card to form a blackjack.
With single-hand play, the house edge on the insurance bet of is 2-15%, depending on decks and cards played.
