What Is Blackjack?
Blackjack is one of the most popular card games in online casinos worldwide. Also known as "21," the objective is straightforward: beat the dealer by having a hand value closer to 21 without going over. Despite its simple goal, blackjack offers layers of strategic depth that keep players engaged for decades.
Basic Rules of Blackjack
The game is played with one or more standard 52-card decks. Card values work as follows:
- Number cards (2–10): Face value
- Face cards (Jack, Queen, King): Worth 10 points each
- Ace: Worth 1 or 11 points, depending on what benefits your hand
Each round begins with players placing their bets. The dealer then distributes two cards to each player (face up) and takes two cards themselves — one face up, one face down (the "hole card").
Player Actions Explained
Once cards are dealt, players choose from the following actions:
- Hit: Request an additional card from the dealer.
- Stand: Keep your current hand and end your turn.
- Double Down: Double your initial bet in exchange for receiving exactly one more card.
- Split: If you have two cards of equal value, split them into two separate hands, each with its own bet.
- Surrender: Forfeit half your bet and end the round early (not available in all variants).
Understanding the Dealer's Rules
Unlike players, the dealer follows fixed rules with no room for strategy. In most variants, the dealer must hit on 16 or less and stand on 17 or more. Some versions use a "soft 17" rule where the dealer hits on a soft 17 (Ace + 6), which slightly increases the house edge.
What Is a "Blackjack"?
A "blackjack" (also called a "natural") is when your initial two cards total 21 — typically an Ace paired with a 10-value card. This usually pays out at 3:2 odds, though some tables pay 6:5, which is less favorable for the player.
