How do you play blackjack?

The 60-second version

Blackjack is a card game between you and the dealer. You each try to build a hand that totals closer to 21 than the other — without going over. Number cards score their face value, face cards (J, Q, K) count as 10, and an Ace counts as 1 or 11 (whichever helps). If your first two cards are an Ace plus a ten-value card, that's a natural blackjack and usually pays 3:2.

Everything else in the game — hitting, standing, doubling, splitting, insurance — is just deciding how to build that hand once you've seen your first two cards and the dealer's up-card.

The table and the players

A blackjack table seats one dealer and up to seven players. Every player plays against the dealer, not against each other. That's the single most important rule to internalise: what the other players do at your table has no mathematical effect on your expected value. A bad player on third base does not "take the dealer's bust card" — the next card is random either way.

Each seat has a betting circle. Before any cards are dealt, you place chips in your circle. Once the dealer says "no more bets", the deal begins.

The deal, step by step

1. You bet. Chips go in the circle.
2. First card, face up, to every player. Left to right.
3. Dealer's first card, face up. This is the up-card — the single most important piece of information in the game.
4. Second card, face up, to every player.
5. Dealer's second card, face down. This is the hole card.
6. Insurance offer (only if the up-card is an Ace).
7. Each player acts in turn, left to right, and decides what to do with their two cards.
8. Dealer reveals the hole card and plays out their hand under fixed rules.
9. Payouts.

That's one round. In our fantasy league, each round is one hand — win, lose, or push — and every hand adjusts your chip stack, which is what the weekly leaderboard ranks.

What your options actually mean

Once it's your turn, you have up to five choices. Not all are available on every hand.

• Hit — take another card. You can hit as many times as you want until you stand or bust.
• Stand — take no more cards. Your hand is locked.
• Double down — double your bet, take exactly one more card, and stop. Only allowed as your first action on a two-card hand. This is the move that makes basic strategy profitable — doubling a hard 11 versus a dealer 6 is one of the highest-EV plays in the game.
• Split — if your two cards are the same rank (two 8s, two Aces, two 6s), you can put up a second bet equal to the first and play each card as its own hand. Aces almost always get one card each and then stop.
• Surrender (not offered everywhere) — give up half your bet and end the hand immediately. Useful on a hard 16 versus a dealer 9, 10, or Ace.

How the dealer plays

The dealer doesn't get to think. They follow a fixed rule set that you should memorise:

• Dealer hits any total of 16 or less.
• Dealer stands on 17 or higher.
• Soft 17 rule: some tables have the dealer hit soft 17 (called H17), others stand (S17). H17 is slightly worse for you — about 0.2% worse house edge — because the dealer draws more cards to a hand that could otherwise stiff and bust. Our fantasy league runs H17 so basic-strategy deviations line up with the majority of live casinos.

Because the dealer's hand is mechanical, you can compute exactly how often they bust from every up-card. The short version: dealers bust most often on 4, 5, and 6 (the "bust cards") and least often on 9, 10, and Ace.

How your hand pays

• Win: 1:1 on your bet. Bet 100, get 100 profit back plus your original 100.
• Blackjack (Ace + ten on the first two cards, and the dealer doesn't also have blackjack): 3:2. Bet 100, get 150 profit. Never sit at a 6:5 blackjack table — it triples the house edge.
• Push (you and the dealer tie): bet returned, no profit, no loss.
• Lose or bust: bet lost.
• Insurance (side bet when the dealer shows an Ace): pays 2:1 if the dealer has blackjack. Mathematically a bad bet unless you're counting cards and know the deck is ten-rich.

A worked example

You bet 100. You're dealt a 10 and a 6 (hard 16). Dealer shows a 10.

You look at basic strategy: 16 versus 10 is one of the worst spots in the game. If surrender is available, surrender — lose 50 instead of an expected 54. If not, hit. Standing on 16 versus 10 loses about 54% of the time; hitting loses about 54% of the time too, but by fractionally less, and the small edge compounds over thousands of hands.

You hit. You catch a 4. Now you have 20. Stand.

Dealer flips the hole card: 7. Dealer total is 17. They stand.

You win. +100 chips. That's one hand — the smallest unit in the fantasy league, and the reason a few thousand well-played hands can climb an entire tier.

Frequently asked

Do I need to count cards to win? No. Basic strategy alone brings the house edge under 0.5% on a standard game. Counting is what turns a small edge into a player edge — you can get very good at blackjack without ever counting.

Is blackjack a game of skill or luck? Both. Any single hand is luck. A thousand hands is skill: correct basic-strategy players lose about 0.5% of their action, random players lose 2–3%. Over a weekly league round, the skill gap is enormous.

Is 21 the same as blackjack? Casually yes. Strictly, "21" is the target total; "blackjack" is the game, and also the specific two-card 21 that pays 3:2.

Can the dealer hit after they reach 17? Only on soft 17 at H17 tables. Any hard 17 or higher, they must stand.

What's the smallest thing I can do today to get better? Learn the four sentences of basic strategy for hard totals: always hit 8 or less, always stand on 17+, stand on 12–16 vs a dealer 2–6, hit 12–16 vs dealer 7–Ace. That single rule captures roughly 70% of the EV of the full chart.
