📖 Blackjack Rule Book

The goal

Beat the dealer's hand without going over 21. You win if your total is higher than the dealer's, or if the dealer busts (goes over 21). You don't need 21 — you need to beat the dealer.

Card values

Number cards (2–10) are worth their face value.
Jack, Queen, King are each worth 10.
An Ace is worth 11 or 1 — whichever helps more. A hand using an ace as 11 is called soft (e.g. A-6 is a "soft 17").

Blackjack (a "natural")

An Ace + any 10-value card on your first two cards is a blackjack. It beats any other 21 and pays 3:2 (bet 2, win 3), unless the dealer also has blackjack — then it's a push (tie).

The dealer's rules

The dealer has no choices. They reveal their hole card and must draw until reaching 17 or more, then stop. In this trainer the dealer stands on soft 17 (S17), the more common and player-friendly rule.

Your options each hand

Hit — take another card. You can keep hitting until you stand or bust.
Stand — take no more cards.
Double — double your bet and take exactly one more card. Only on your first two cards.
Split — if your two cards are a pair, split them into two separate hands (each gets a new second card) and play each in turn. You can double after splitting (DAS). Split Aces get just one card each. Up to 4 hands.

How this trainer works

Every decision you make is graded against basic strategy — the mathematically optimal play for each hand vs. each dealer upcard. Then the hand plays out for real: hit as many times as you like, split and play each hand, then the dealer draws and the round is settled win/lose/push. Your accuracy %, streak, and per-type breakdown track your progress toward the 95% mastery goal. Wrong answers and weak categories come up more often.

Basic strategy in one breath

Dealer's 2–6 are "bust cards" — play cautiously, let them bust. Stand on stiff totals (12–16), and double your strong hands to press your edge.
Dealer's 7–Ace are strong — assume they have a made hand, so keep hitting stiff totals until you reach 17+.
Always split Aces and 8s; never split 10s or 5s.
You can never bust by hitting a soft hand (≤ soft 17), so hit or double them freely.

Card counting (Hi-Lo)

Turn on counting mode to train the Hi-Lo system: each 2–6 is +1, each 7–9 is 0, each 10/J/Q/K/Ace is −1. Add these up as cards appear (the running count), then divide by the decks remaining to get the true count. A high positive count means lots of tens and aces remain — good for the player. Counting doesn't change the correct play of most hands; it tells you when the deck favors you so you'd bet more.

Bet sizing — where the money is made

Counting only pays off if you bet more when the count is high. With the bet-sizing trainer on, you'll size each bet before the deal using a 1–12 unit ramp: true count ≤1 → 1 unit, 2 → 2, 3 → 4, 4 → 8, 5+ → 12. Flat-betting a counted shoe earns nothing; the spread is the edge. The Bankroll stat tracks your net units (blackjacks paid 3:2) so you can watch good betting compound over a session.
