As per blackjack rules, multiple deck games typically consist of an even number of decks, but these blackjack rules are not set in stone. The two main reasons many casinos use multiple decks in blackjack: rules of thumb can show that they allow the dealer to deal more hands, and they reduce advantage gained from card counting.
Blackjack Rules – Double Down
Players can do most anything they want as far as hitting and standing. Should a player get a Blackjack, rules state that the payoff is 150% more than the original bet. Doubling down is restricted to 2-card hands, usually totaling 9, 10, or 11, although some blackjack rules allow doubling down on any 2-card hand. If your first two cards provide you with the appropriate total and your cards were dealt face down, turn them over and put them on the dealer’s side of the betting square, as blackjack rules dictate. If your first two cards provide you with the appropriate total and your cards were dealt face up, point to them and say “double” when the dealer prompts you for a card and put an equal amount of chips next to those already in the betting box. The dealer will give you one more card only, and then he/she will move on to the next hand, as per traditional blackjack rules.
Blackjack rules on splitting are tricky. Blackjack rules explain that if you split a pair, you have to place an equal amount of chips for the other card. Blackjack rules emphasize that you are now playing two hands, each a separate hand of blackjack. Rules mention that if you split two aces, you only get one card. If it’s a ten, the total is 21, but is not considered a Blackjack. Rules to know!
