It is played multiple decks of 52 cards, and is the most widely played casino banking game in the world.
How to Win
- Get 21 points on the player’s first 2 cards (called a “blackjack” or “natural”), without a dealer blackjack
- Reach a final score higher than the dealer without exceeding 21
- Let the dealer draw additional cards until their hand exceeds 21
Player Decisions
After receiving an initial 2 cards, the player has up to 4 standard options: “hit”, “stand”, “double down”, or “split”. Some games give the player a fifth option, “surrender”.
- Hit: Take another card from the dealer.
- Stand: Take no more cards, also known as “stand pat”, “stick”, or “stay”.
- Double down: The player is allowed to increase the initial bet by up to 100% in exchange for committing to stand after receiving exactly one more card.
- Split: If the first two cards of a hand have the same value, the player can split them into 2 hands, by placing a second bet equal to the first. The hands will now be treated as 2 separate hands with equal bet amounts.
