Blackjack
Blackjack — also called Twenty-One — is the most widely played casino banking game in the world. Unlike most casino games, blackjack involves meaningful player decisions that directly affect the outcome. With perfect basic strategy, the house edge can be reduced to as low as 0.28% on single-deck games, making it one of the best-value games in the casino. The game originated in French and Spanish casinos in the 18th century and spread globally after the publication of Edward Thorp's Beat the Dealer in 1962, which proved that card counting could give players a mathematical edge.
Rules & Gameplay
The objective is to beat the dealer by having a hand value closer to 21 without exceeding it ('busting'). Card values: Ace = 1 or 11, face cards = 10, all others = face value. Each player and the dealer receive two cards; the dealer's second card is face down (hole card). Players then choose: Hit (draw a card), Stand (keep current hand), Double Down (double the bet and draw exactly one card), Split (divide a pair into two hands with equal bets), or Surrender (forfeit half the bet and end the hand). If the dealer's upcard is an Ace, an Insurance bet of up to half the original wager is offered. A natural blackjack (Ace + 10-value) pays 3:2 (beware games paying 6:5). The dealer must hit on 16 or below and stand on 17 or above (rules vary for soft 17).
Basic Strategy
Basic strategy is a mathematically derived set of decisions for every possible player hand versus dealer upcard. Key principles: always split Aces and 8s; never split 5s or 10s; double down on hard 11 against dealer 2–10, on hard 10 against 2–9, on hard 9 against 3–6; stand on hard 17+; hit hard 12–16 against dealer 7+; surrender hard 16 against dealer 9, 10, or Ace (where allowed). On soft hands: always hit soft 17 or below; stand on soft 19+; double soft 18 against dealer 3–6. Memorise a basic strategy chart before playing — deviating from correct strategy adds 1–4% to the house edge. Avoid insurance (even money), which carries a 7.7% house edge.
