How to play

Blackjack from zero

Everything you need to sit down at a table for the first time. Five minutes, no jargon left unexplained.

The goal

You are not playing against other players — only against the dealer. The goal is to end the round with a card total higher than the dealer's without going over 21. Go over 21 and you bust: you lose immediately, no matter what the dealer has.

Card values

Cards 2 through 10 are worth their printed number.
Jack, Queen and King ("face cards") are each worth 10.
An Ace is worth 1 or 11 — whichever helps you more, decided automatically. It counts as 11 unless that would bust you, in which case it counts as 1.

A hand containing an ace that is currently counted as 11 is called a soft hand (for example, Ace + 6 is "soft 17"). It's called soft because you can never bust by taking one more card — the ace simply drops to 1 if needed. Any other hand is a hard hand (10 + 7 is "hard 17").

The flow of a round

Bet. Place your wager before any cards are dealt.
Deal. You receive two cards face up. The dealer gets two cards: one face up (the upcard) and one face down (the hole card).
Blackjack check. If your first two cards are an Ace + a ten-value card, that's a blackjack (or "natural") — the best possible hand. It wins immediately at 3:2 unless the dealer also has blackjack, in which case the round is a tie. If the dealer's upcard is an Ace or a ten, the dealer peeks at the hole card first to check for their own blackjack.
Your turn. You act as many times as you like, choosing from the actions below, until you stand, bust, or double.
Dealer's turn. The dealer reveals the hole card and plays by fixed rules — no decisions (see below).
Settle. Hands are compared and bets are paid.

Your actions

Hit: Take one more card. You may keep hitting until you stand or bust.
Stand: Take no more cards. Your total is locked in and the turn passes on.
Double down: Double your bet, receive exactly one more card, and stand automatically. Allowed on any two-card starting hand at this table. High reward when the odds favor you, but you give up the right to keep hitting.
Split: If your two cards are the same rank (a pair), you may split them into two separate hands, placing a second bet equal to your first. Each hand gets a new second card and is then played on its own. Split aces are an exception: each ace receives just one card.
Surrender: Give up your starting hand immediately and take back half your bet. Only available as your very first decision, and only worth it in a few clearly losing spots (the analyzer will show you which).

Dealer rules

The dealer has no choices. They must hit on 16 or less and stand on 17 or more — at this table, that includes standing on soft 17. The dealer never doubles, splits or surrenders. If the dealer busts, every player hand still standing wins.

This fixed behavior is the entire reason strategy exists: because the dealer's play is mechanical, the correct response to every situation can be calculated — which is exactly what the rest of this site does.

Payouts

Blackjack (natural): pays 3:2 — bet 10, win 15.
Regular win: pays 1:1 — bet 10, win 10.
Tie ("push"): nobody wins; your bet is returned.
Loss or bust: your bet is gone.
Surrender: you lose exactly half your bet.

Insurance and even money

When the dealer's upcard is an Ace, you'll be offered insurance: a side bet of up to half your stake that pays 2:1 if the dealer's hole card turns out to be a ten — that is, if the dealer has blackjack. If you hold a blackjack yourself, the same offer is dressed up as even money: a guaranteed 1:1 payout instead of risking a push.

Decline both, always. For insurance to break even, the hole card would need to be a ten more than 1 time in 3. It's actually a ten about 4 times in 13 — roughly 30.8% — so the bet loses about 7.7% of its value on average, making it one of the worst wagers on the table. Even money is mathematically the identical bet in disguise: your blackjack is worth more played straight.

Side bets

Many tables offer optional side bets placed alongside your main wager — the most common are Perfect Pairs (betting your two cards will be a pair) and 21+3 (betting your two cards plus the dealer's upcard form a poker hand). They pay big multiples and cost nothing to skip.

Skip them. Side bets typically carry a house edge between 2% and 10% or more — several times worse than the main game played with basic strategy. They exist because they're profitable for the casino, not for you.

Quick glossary

Bust: A total over 21. An immediate loss.
Soft hand: A hand with an ace counted as 11. Can't bust on the next card.
Hard hand: A hand with no ace, or with every ace forced to count as 1.
Push: A tie with the dealer. Your bet is returned.
Basic strategy: The mathematically best action for every hand vs. upcard combination — the strategy behind every number on this site.
Shoe: The box holding the shuffled decks (six of them at this table) that cards are dealt from.
Pat hand: A hand of 17 or more that you'd normally stand on.
Stiff hand: A hard 12–16: too weak to feel safe, risky to hit. Where most of the hard decisions live.
First base / Third base: The seats that act first and last each round. Position doesn't change your odds.
Paint: Any face card — Jack, Queen or King.
Snapper: Old-school slang for a blackjack.
Monkey: What a player hoping for a ten-value card yells for. Nobody fully agrees on why.
Burn card: A card discarded face-down after the shuffle before dealing begins.
Toke: A tip for the dealer, often bet on their behalf.
Heads-up: Playing alone against the dealer, no other players at the table.

Common beginner mistakes

Taking insurance or even money. Covered above — it's a losing bet wearing a safety vest.
Copying the dealer (hitting to 17, never doubling or splitting). The dealer's rules only work because players must act — and bust — first. Mimicking them roughly quintuples the house edge.
Never doubling or splitting. These are the only moments you can press money onto the table when the odds favor you. Skipping them gives that edge back.
Splitting tens. A 20 wins about 85% of the time when it wins or pushes — breaking it up turns one near-certain winner into two average hands.
Playing hunches and streaks. The shoe has no memory. A dealer who has busted three times in a row is exactly as likely to bust again as the table on this site says.
Betting systems like the Martingale (doubling your bet after every loss). No betting pattern changes the expected value of a single hand; it only changes how quickly a bad run empties your pockets.
Sitting at a 6:5 table. Some tables pay blackjack at 6:5 instead of 3:2. That single rule change costs you more than every playing mistake on this list combined. Read the felt before you sit.

Card counting, in brief

Card counting is not memorizing every card — it's tracking one running number that estimates whether the remaining shoe is rich in tens and aces (good for the player) or small cards (good for the dealer). In the common Hi-Lo system, low cards (2–6) count +1, high cards (10–A) count −1, and the player bets more when the count is high. It works because a ten-rich shoe produces more player blackjacks at 3:2 and more dealer busts.

It is legal everywhere — it's just thinking — but casinos are private businesses and may shuffle early, restrict your bets, or ask you to leave if they suspect it. In practice, modern six-deck games with frequent shuffling and continuous shuffling machines have made counting largely impractical for casual players. Treat it as interesting math, not an income plan.

Frequently asked questions

What's the house edge if I play perfectly?: Under this site's rules, roughly 0.5–0.6% — among the lowest of any casino game. Played by feel, it's commonly 2–4%.
Does the dealer win ties?: No — ties push and your bet is returned. That rule belongs to informal home games, and it's brutal: it alone would swing the edge massively to the house.
Do other players' decisions hurt my odds?: No. A bad player "taking the dealer's bust card" is exactly as likely to take the card that would have beaten you. It feels real; it isn't.
Does my seat at the table matter?: Mathematically, not at all.
Is there a blackjack odds calculator on this site?: Yes — the hand analyzer computes the exact expected value of every action for any hand.
Where do I start as a complete beginner?: Learn the flow of a round on this page, then memorize the strategy chart a section at a time — hard totals first, since that's where most hands land.
