What Is Blackjack?

Blackjack is one of the most popular casino card games in the world, and for good reason — it combines simplicity with strategy, giving players a genuine opportunity to influence the outcome through skillful decisions. The core objective is straightforward: get a hand value closer to 21 than the dealer without going over (busting).

Card Values in Blackjack

Before you sit down at a table, you need to know what each card is worth:

  • Number cards (2–10): Worth their face value.
  • Face cards (Jack, Queen, King): Each worth 10 points.
  • Ace: Can be worth either 1 or 11, whichever benefits your hand most.

A hand containing an Ace counted as 11 is called a soft hand. A hand where the Ace must count as 1 (to avoid busting) is a hard hand.

How a Round Is Played

  1. Place your bet before cards are dealt.
  2. Cards are dealt: Each player receives two cards face up. The dealer gets one card face up and one face down (the hole card).
  3. Players act: Starting to the dealer's left, each player decides their action.
  4. Dealer reveals: After all players act, the dealer flips their hole card and plays by fixed rules.
  5. Payouts: Winning hands are paid, losing hands are collected.

Player Actions Explained

ActionWhat It Means
HitDraw another card to increase your hand value.
StandKeep your current hand and end your turn.
Double DownDouble your bet and receive exactly one more card.
SplitIf you have two cards of the same value, split them into two separate hands (each with a new bet equal to the original).
SurrenderForfeit half your bet and end the hand early (not available at all tables).

Dealer Rules

Unlike players, the dealer doesn't make strategic decisions. Dealers must follow fixed house rules:

  • The dealer must hit on any hand totaling 16 or less.
  • The dealer must stand on any hand totaling 17 or more.
  • Some tables use soft 17 rules, requiring the dealer to hit on a soft 17 (Ace + 6). This slightly increases the house edge.

What Is Blackjack (Natural)?

A "blackjack" or "natural" is when your first two cards are an Ace and any 10-value card. This typically pays 3:2 (though some tables pay only 6:5 — always check before playing). If the dealer also has a natural, it's a push (tie) and your bet is returned.

Insurance Bets

When the dealer's face-up card is an Ace, players are offered an insurance bet — a side bet of up to half their original wager that pays 2:1 if the dealer has blackjack. From a mathematical standpoint, insurance is generally a poor bet for most players and is best avoided unless you are an experienced card counter.

Basic Strategy at a Glance

Blackjack has a mathematically optimal way to play every hand, known as basic strategy. A few key principles:

  • Always split Aces and 8s.
  • Never split 10s or 5s.
  • Double down on 11 (almost always).
  • Stand on hard 17 or higher.
  • Hit on hard 8 or lower.

Learning basic strategy can reduce the house edge to well below 1%, making blackjack one of the best-value games in any casino.
