About the game
Blackjack is the classic casino card game: draw cards to get as close to 21 as possible without going over, while beating the dealer's hand.
How to play
Hit to take another card or stand to keep yours. Face cards are 10, aces are 1 or 11. If your total exceeds 21 you bust; otherwise you win by beating the dealer.
Tips & strategy
["Stand on 17 or more against a dealer's weak card.", 'Double down when the math favors it.', "Assume the dealer's hidden card is a 10."]
Advanced guide
Blackjack is won by basic strategy, not hunches. Memorize the hit/stand rules by dealer up-card: stand on 12-16 when the dealer shows 2-6 (likely to bust), and hit when they show 7 or higher. Treat an ace as 11 unless it would bust you, and avoid insurance.
History & origins
Blackjack descends from 18th-century French card games and is the most-played casino table game.
