What Is Blackjack?
Blackjack is one of the most widely played card games in both land-based and online casinos. The objective is straightforward: beat the dealer by getting a hand value closer to 21 without going over. Despite its simple goal, blackjack rewards players who understand the rules and apply consistent decision-making.
Card Values
- Number cards (2–10): Worth their face value.
- Face cards (Jack, Queen, King): Each worth 10.
- Ace: Worth either 1 or 11, whichever benefits the hand more.
A hand containing an Ace counted as 11 is called a soft hand. For example, Ace + 6 = soft 17. A hand where the Ace must count as 1 is a hard hand.
How a Round Works
- Players place their bets before any cards are dealt.
- Each player and the dealer receive two cards. Players' cards are typically face up; the dealer has one card face up and one face down (the "hole card").
- Players act on their hands in turn.
- The dealer then reveals the hole card and plays out their hand according to fixed rules.
- Hands closer to 21 than the dealer's win; ties (pushes) return the bet.
Player Decisions Explained
Hit
Request an additional card to increase your hand value. You can hit multiple times, but if you exceed 21 you bust and lose the bet automatically.
Stand
Keep your current hand and end your turn. Typically chosen when your total is strong enough to compete with what the dealer might have.
Double Down
Double your original bet and receive exactly one more card. This is an aggressive move best used when you hold a total of 9, 10, or 11 and the dealer shows a weak upcard.
Split
When dealt two cards of the same value, you can split them into two separate hands, each with its own bet equal to the original. Common wisdom: always split Aces and 8s; never split 10s or 5s.
Insurance
Offered when the dealer's upcard is an Ace. A side bet worth half your original stake that pays 2:1 if the dealer has blackjack. Most basic strategy guides advise against taking insurance, as it carries a high house edge.
Dealer Rules
Unlike players, the dealer has no choices to make. Standard rules require the dealer to:
- Hit on any hand totalling 16 or less.
- Stand on any hand totalling 17 or more.
- In some variants, hit on soft 17 (Ace + 6) — check the table rules before playing.
Blackjack Payouts
| Outcome | Payout |
|---|---|
| Winning hand | 1:1 (even money) |
| Natural Blackjack (Ace + 10-value) | 3:2 (standard) or 6:5 (avoid this) |
| Insurance win | 2:1 |
| Push (tie) | Bet returned |
Note: Always seek out tables that pay 3:2 for blackjack. Games paying 6:5 significantly increase the house edge.
Getting Started
Blackjack is an excellent entry point into casino table games. Once you're comfortable with the rules, consider learning basic strategy — a mathematically derived set of decisions for every possible hand combination. Playing correct basic strategy dramatically reduces the house edge and gives you the best possible chance over the long run.
