Blackjack
The Deck Remembers
Get closer to 21 than the dealer without going over, playing from a six-deck shoe. You choose whether to take another card; the dealer does not, and must draw to 17, hitting a soft 17. Doubling and splitting let you put more money on the hands where the odds have moved your way.
Why the Odds Shift as Cards Leave
Every card dealt is a card that will not appear again until the shoe is reshuffled, and that is what makes blackjack different in kind from roulette. A wheel has no memory: the odds on the next spin are identical to the last. A shoe has nothing but memory. When the cards already played were mostly small, what remains is rich in tens and aces, which favors the player - more natural twenty-ones, more hands worth doubling, and a dealer who busts more often. This is sampling without replacement, and it is the reason blackjack, unlike roulette, can have a beatable edge.
How to play
- Hit (H) takes another card, stand (S) ends your turn, and double (D) takes exactly one more for twice the bet.
- A pair can be split (T) into hands played separately, up to four; surrender (R) gives up half the bet instead.
- The dealer's face-up card is the most useful piece of information on the table.
- Going over 21 loses immediately, whatever the dealer does afterward.
