As a player, the fewer deck the better. Also, the fewer the decks, the fewer hands per hour you play because the dealers need to shuffle the cards more often. The house also has an advantage in the way the cards are dealt when more than two decks are used Blackjack is a simple game to learn. Each card has a numerical value. For example, a five is worth five, seven is worth seven, and so forth.
All face cards are worth ten, as are all tens.
Aces are worth either one or eleven. If you're dealt an ace, it's up to your discretion to count it as one or eleven. For example, if you have an ace and a seven in your hand, it can be counted as eight or eighteen. Because you have the option of playing the ace either way, a hand containing an ace is called a soft hand. A hand with no aces is in turn called a hard hand.
