What winning at blackjack looks like and why you should learn the basics
Blackjack is one of the most approachable casino games because it pairs simple rules with meaningful player decisions. Your goal is straightforward: get a hand value closer to 21 than the dealer’s hand without going over (busting). A two-card 21 (an ace and a 10-value card) is called a “blackjack” and usually pays 3:2, which makes knowing how to play each hand correctly worth the effort.
As you learn, focus on two things: understanding how card values work and recognizing the limited but important choices you’ll make on each turn. With that foundation you can apply basic strategy rules that reduce the house edge and help you make the mathematically best move in common situations.
Table setup, card values, and the choices you’ll make
Table layout and initial deal
Blackjack is dealt at a semicircular table with one dealer and up to seven players. Before cards are dealt you place a bet in your betting spot. The dealer gives two cards to each player and two to themselves—usually one dealer card face up (the upcard) and one face down (the hole card) in casinos that use hole-card rules.
- Objective: Beat the dealer without exceeding 21.
- Blackjack: Ace + 10-value pays 3:2 in most games.
- Payouts: Winning a normal hand pays 1:1; ties (pushes) return your wager.
Card values and hand types
Card values are simple: number cards are worth their face value, face cards (J, Q, K) are worth 10, and aces count as 1 or 11—whichever benefits your hand. That flexibility creates two important hand types:
- Hard hands: Hands without an ace counting as 11 (or where ace must count as 1 to avoid busting).
- Soft hands: Hands containing an ace counted as 11 (e.g., Ace+6 = “soft 17”), which can’t bust with one hit because the ace can revert to 1.
Player options: how you control each hand
Once you see your initial cards, you choose from a short list of actions. Each choice affects risk and potential reward:
- Hit: Request another card. Use to improve low totals.
- Stand: Keep your current total and end your turn.
- Double down: Double your bet, take exactly one more card, then stand. Best when your total has favorable odds versus the dealer’s upcard.
- Split: If you have a pair, split into two hands and place an equal bet on the new hand. Splitting changes strategy dramatically for pairs like 8s or aces.
- Surrender (if offered): Forfeit half your bet to end the hand early—valuable when you face a very unfavorable dealer upcard.
Knowing these rules puts you in control of each decision. Next, you’ll learn the dealer’s rules and the specific strategic guidelines—basic strategy charts and examples—that tell you when to hit, stand, double, split, or surrender to minimize the house edge.
Dealer rules and how they affect your choices
The dealer’s behaviour is automatic and fixed by casino rules—this is the key difference between you and the house. Most casinos require the dealer to hit until reaching 17, but that 17 can be either a “soft 17” (an ace counted as 11 plus other cards) or a “hard 17.” Two common variants:
- Dealer stands on soft 17 (S17): Dealer stops on any 17, including A+6. This is slightly better for the player.
- Dealer hits on soft 17 (H17): Dealer takes another card on A+6. This increases the house edge a bit and slightly changes doubling/splitting strategy.
Casinos that use the hole-card rule (dealer checks for blackjack when showing an ace or ten) prevent players from losing extra money on doubles or splits against a dealer blackjack. If the dealer peeks and has blackjack, your additional actions (extra cards after doubling/splitting) are usually voided—know whether the table peeks before you play.
Basic blackjack strategy: core rules for hard, soft, and paired hands
Basic strategy is a set of mathematically optimal moves based on your hand and the dealer’s upcard. Memorize the key rules below or keep a chart—following them reduces the house edge to its minimum for standard games.
Hard totals (no usable ace)
- 8 or less: Hit.
- 9: Double against dealer 3–6, otherwise hit.
- 10: Double against dealer 2–9, otherwise hit.
- 11: Double against dealer 2–10, hit vs. ace.
- 12: Stand against dealer 4–6, hit otherwise.
- 13–16: Stand against dealer 2–6, hit against 7–ace.
- 17+: Always stand.
Soft totals (ace counted as 11)
- A2–A3 (soft 13–14): Double vs dealer 5–6, otherwise hit.
- A4–A5 (soft 15–16): Double vs 4–6, otherwise hit.
- A6 (soft 17): Double vs 3–6, otherwise hit.
- A7 (soft 18): Stand vs 2,7,8; double vs 3–6; hit vs 9–ace.
- A8–A9 (soft 19–20): Generally stand.
Pairs (splitting)
- Always split aces and 8s.
- Never split 5s or 10s (treat 5s as a 10 and play normally).
- Split 2s and 3s vs dealer 2–7; otherwise hit.
- Split 4s only vs 5–6 (otherwise hit).
- Split 6s vs 2–6; split 7s vs 2–7.
- Split 9s vs 2–6 and 8–9; stand vs 7, 10, ace.
Surrender (when available): surrender 16 vs dealer 9–ace; surrender 15 vs dealer 10 is often recommended. Use surrender sparingly but it’s valuable when offered.
When table rules and number of decks change the strategy
Basic strategy above assumes typical rules (four to eight decks, dealer stands on soft 17). But small changes affect the math:
- Number of decks: Fewer decks slightly improve the player’s odds and can change a couple of doubling/splitting decisions. Single- or double-deck games favor the player more than eight-deck shoes.
- Dealer hits soft 17 (H17): When the dealer hits soft 17, the house edge increases; you should be slightly more conservative with doubles and splits in a few spots.
- Dealer peek and surrender rules: Early surrender vs late surrender and whether the dealer checks for blackjack affects whether you can safely double or split into a likely dealer blackjack.
Before you sit down, scan the table rules. If they differ from the standard assumptions, pull the specific basic strategy chart for that rule set or adjust the few decisions noted above. With rule-aware basic strategy, you’ll make the best possible choices every hand and keep the house edge as small as it can be.
Putting strategy into practice
Learning basic strategy is only the start — real improvement comes from deliberate practice, paying attention to table rules, and managing your bankroll and emotions. Play low-stakes sessions (or use a free simulator) to internalize common decisions, avoid side bets and insurance unless you understand their math, and always check whether the table uses H17/S17 and how many decks are in play. For deeper reading and calculators that adjust for rules and decks, see Wizard of Odds blackjack guide.
- Practice with charts until moves become automatic.
- Adjust to the specific table rules before increasing your bet size.
- Use bankroll rules (session limits, unit sizing) to protect your play and reduce tilt.
Above all, treat blackjack as a skill game where steady, rule-based choices beat impulse decisions. With patience and the right approach you’ll make better choices at the table and keep the house edge as small as possible.
Frequently Asked Questions
Is blackjack a game of skill or luck?
Both. The cards dealt are random (luck), but player decisions — hit/stand/double/split/surrender — directly affect long-term results. Learning and applying basic strategy reduces the house edge and is how skill influences outcomes.
Should I ever take insurance?
In most cases no. Insurance is a separate bet with a negative expected value for players who do not know exact card counts. Unless you are counting cards and have a very strong reason, avoid insurance and focus on basic strategy.
How much do table rules (decks, S17/H17) change strategy?
Table rules can change a few specific decisions and the overall house edge. Fewer decks and dealer stands on soft 17 generally favor the player, while H17 and more decks favor the house. Always check the posted rules and, when possible, use a strategy chart matched to that exact rule set.
