How to Play Blackjack: Rules, Strategy, and Tips

Blackjack is a card game where you compete against the dealer, aiming to get a hand total as close to 21 as possible without going over. Number cards are worth their face value, face cards are worth 10, and aces can be 1 or 11. Getting exactly 21 with your first two cards is called a 'blackjack' and pays 3:2.

Each round begins with the player placing a bet and receiving two cards face up. The dealer receives one card face up and one face down. You then decide to hit (take another card), stand (keep your hand), double down (double your bet and take one card), or split (if you have a pair).

Basic strategy is a mathematically optimal way to play every hand. It tells you exactly when to hit, stand, double, or split based on your cards and the dealer's upcard. Following basic strategy reduces the house edge to approximately 0.5%.

Popular variations include European Blackjack (dealer doesn't peek for blackjack), Spanish 21 (played without 10s), and Blackjack Switch (you play two hands and can swap top cards). Each variation has slightly different rules that affect the house edge.

Always follow basic strategy rather than gut feelings. Never take insurance—it's a sucker bet with a high house edge. Start with low-stakes tables to learn the game without risking too much. Look for tables that pay 3:2 for blackjack rather than 6:5.
