What Is Blackjack?

Blackjack — also known as "21" — is one of the most widely played casino card games in the world. Unlike many casino games where you compete against other players, in blackjack your only opponent is the dealer. The goal is straightforward: get a hand value closer to 21 than the dealer without going over.

Card Values Explained

Understanding card values is the first step to playing blackjack confidently:

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

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.

The Basic Flow of a Blackjack Round

  1. Place your bet before any cards are dealt.
  2. Two cards are dealt to each player and the dealer. Players receive both cards face up; the dealer gets one face up and one face down (the "hole card").
  3. Players act on their hands one at a time, choosing from the available actions.
  4. The dealer reveals their hole card and plays according to fixed rules.
  5. Hands are compared and bets are settled.

Player Actions

Once you've seen your initial two cards, you have several choices:

  • Hit: Request another card. You can hit as many times as you like until you stand or bust.
  • Stand: Keep your current hand and end your turn.
  • Double Down: Double your original bet and receive exactly one more card. Best used on totals of 9, 10, or 11.
  • Split: If your two cards are a matching pair, you can split them into two separate hands, each with its own bet.
  • Surrender: Available in some variants — forfeit half your bet and withdraw from the round.

How the Dealer Plays

The dealer follows a strict, fixed set of rules — they don't make judgment calls. Typically:

  • The dealer must hit on any hand totalling 16 or below.
  • The dealer must stand on any hand totalling 17 or above.
  • In some versions, the dealer hits on a "soft 17" (Ace + 6). Check the table rules before sitting down.

Blackjack — The Premium Hand

If your initial two cards total exactly 21 (an Ace plus any 10-value card), that's a natural blackjack. This typically pays 3:2, meaning a £10 bet returns £15 profit. Be aware that some tables offer 6:5 payouts — this is less favourable, so seek out 3:2 tables wherever possible.

Key Takeaways for New Players

  • Always check whether the table pays 3:2 or 6:5 for blackjack before playing.
  • Learn the dealer's fixed rules — they're the same at every reputable table.
  • Blackjack rewards skill: learning basic strategy can meaningfully reduce the house edge.
  • Start at lower-stake tables while you're getting comfortable with the flow of the game.
