Blackjack is a card game where players try to reduce their hand size to 21 by drawing cards until they reach a dealer blackjack. Aces are high and two through seven are low.
The value of a card is its face value plus any additional wild cards.
One deck of cards is used in blackjack. The standard 52-card deck contains two jacks, two queens, two kings, two tens, two nines, and one spot card, which is the Ace of Spades.
Aces are worth 1 point each, 2 through 10 are worth face value, and any card that is not one of the above ranks is worth zero.
When playing blackjack, the goal is to hit or exceed the dealer’s hand total (usually 21). To achieve this, players generally draw cards until they are either forced to discard or have at least one card that equals or exceeds the dealer’s hand total.
In either case, the player must then replace any cards that were drawn with new ones from their remaining deck.
When playing blackjack online with a real money option, some casinos will weight the deck differently in order to adjust for house edge (the difference between what the casino makes from house bets and what players lose). The higher-value cards (Ace through 10) are usually weighted more than the lower-value cards (two through seven), in order to even out the advantage that higher-value hands have over lower-value hands in traditional casino games like craps and roulette.
