Each round starts with two cards; values: numbered cards equal face value; face cards count ten; Aces count eleven or one, chosen to avoid bust.
Dealer reveals one face-up card; policy varies: in many venues dealer hits on soft 17; stands on hard 17 or higher.
Core rule set guides decisions by total, visible card, deck count. For two-card totals 12 through 16, standing against dealer 2 through 6 improves odds; hitting against dealer 7 through Ace reduces expectation. Doubling down allowed on totals 9, 10, 11 when dealer shows low card; take this move when rules permit.
Practice phase relies on free simulations; memorize core chart; begin with low stakes; log results to refine plan.
House edge under favorable rules remains near 0.3–0.6% when you follow core plan, track outcomes, adjust bets cautiously.
Card Values, Objective of Play
Start by memorizing card values: Aces count 1 or 11; 2 3 4 5 6 7 8 9 carry their face value; J Q K count 10.
This baseline supports quick decisions when dealer shows a card. Total beyond 21 results in bust, hands within 21 stay active.
Goal is reaching 21 or staying below while maximizing hand strength. Soft hands use Ace as 11 for extra flexibility; hard hands rely on numeric totals without 11 from Ace.
Soft vs Hard Hands
Soft hand contains Ace counted as 11; example Ace plus 7 equals 18. Aces can also count as 1 if needed to avoid bust.
Decision Points
Possible moves: hit, stand, double down, split pairs.
Dealer upcard shapes strategy: upcard 2 through 6 often prompts standing on totals near 12 through 16 due to probability of bust; upcard 7 through Ace favors taking another card to improve hand.
Round Flow: From Bet to Payout
Stake placement precedes dealing; minimum 1 unit, maximum 500 per hand; table rules vary by venue; cash or chips must equal chosen stake; adjust chip mix to hit limit precisely.
Shoe usually contains six to eight decks; after bets lock, dealer exposes upcard, keeps one face-down card; dealing proceeds clockwise, giving each participant two cards; players view own totals; dealer hides second card until payoff stage.
Decision phase follows dealing; core moves: hit; stand; double; split; rules vary on splitting pairs (Aces, Eights) plus re-splitting options; soft totals receive special handling; aim to double on soft totals when dealer upcard is 5 or 6 for totals 13 through 18; avoid doubling on hard 12 against 3; these guidelines boost expected value.
Round end triggers outcome resolution; wins yield 1:1 payout; naturals (first two cards totaling 21) pay 3:2; insurance option costs half of initial stake; if dealer upcard is Ace, insurance pays 2:1 when dealer ends with natural; pushes refund; doubled or split hands count as separate bets with corresponding payouts.
Player Actions: Hit; Stand; Double Down; Split
Always hit if hand total ≤ 11, regardless of dealer upcard. Stand on 17 or more, any upcard. Double down on 9–11 when dealer shows 3–6. Split Aces or 8s whenever permissible, avoid splitting 5s or 10s.
These choices shape round outcomes. Note that table values reflect common 2-deck or 6-deck variants; house rules may shift thresholds slightly. For example, 2-deck or 6-deck variants modify splits: avoid separating 10s; split Aces yields two separate hands, creating two chances to improve total.
| Action | When to Choose | Rationale |
|---|---|---|
| Hit | Hand total ≤ 11 | Draw for a chance to reach 12–21; bust risk limited |
| Stand | Total 17–21 | Lock in strong hand; avoid bust by drawing |
| Double Down | Total 9–11; dealer upcard 2–6 | One additional card; maximize edge when dealer shows weak card |
| Split | Pair Aces or 8s; rules vary for other pairs | Two chances to improve hands; Aces allow separate draws; avoid splitting 5s, 10s |
Dealer Rules: Hit on Soft 17, Stand on 18+ (Procedures)
Recommendation: know dealer scheme prior to placing bets. In most venues dealer hits soft 17; stands on 18+ totals.
Soft 17 variant: some tables require hit on soft 17; other setups require stand on soft 17. Verify placard at table before seating.
Hard total rule: totals 17+ stand; totals under 17 hit. With soft totals, decisions vary by variant; always check current rule set.
Strategy note: players waiting on dealer outcomes can compare expected values from table rules; when counting cards, adjust expectations; avoid relying on luck alone.
Natural 21 Payouts: Naturals Payouts Guide
Choose tables offering 3:2 on a natural 21. This payout standard remains common at reputable venues; avoid 6:5 variants which cut player return.
Payout math: win equals 1.5x stake, plus stake returned. Example: bet 100, profit 150, total received 250.
Alternative payout 6:5: win equals 1.2x stake; example: bet 100, profit 120, total received 220.
Long run impact: choosing 3:2 format yields higher overall return; replacing with 6:5 increases house edge by roughly 1.4 percentage points, reducing long term gains.
Strategy tips: check rules before seating; confirm payout on naturals; prefer 3:2; verify dealer stands on soft 17; if late surrender available, use it; avoid tables with 6:5 or worse.
Rule Variants
Major markets typically offer 3:2; some venues adopt 6:5 or even 2:1 in special promotions; always read paytable; note promotions may apply only to regular hands not naturals.
Bottom line: under standard rules natural yields solid value; trend toward 3:2 remains common across modern venues; verifying paytable before play prevents surprises.
Common Scenarios: When to Double Down or Split
Double on hard 11 against 2–10; against Ace, hit.
Hard 10: double on 2–9; otherwise hit against upcard 10 or Ace.
Hard 9: double on 3–6; otherwise hit.
Soft 13–14 (A-2, A-3): double on upcards 5–6.
Soft 15–16 (A-4, A-5): double on upcards 4–6.
Soft 17 (A-6): double on upcards 3–6.
Soft 18 (A-7): double on upcards 3–6; otherwise hit.
Pairs: Aces, 8s always split.
2s or 3s: split versus 4–7; otherwise play as a single hand.
4s: split versus 5–6 if DAS allowed; otherwise keep as a total of 8.
5s: never split; treat as 10; double on 9–11 against upcards 2–9 when possible.
6s: split versus 2–6; otherwise hit.
7s: split versus 2–7; otherwise hit.
9s: split versus 2–6, 8–9; stand versus 7, 10, Ace.
10s: never split.
Table Rules and Effects on Your Odds
Pick tables with S17; DAS; late surrender. This combination trims house edge by roughly 0.2% to 0.5% depending on deck mix.
- Deck count: 2- to 4-deck formats yield a tighter edge for players; 8-deck formats push edge higher by roughly 0.2% to 0.6% when other rules stay constant.
- Payout on natural: 3:2 advantages players; switching to 6:5 raises house edge by about 1.4 percentage points; seek 3:2 where possible.
- Dealer stance: soft 17 rule; dealer stands on soft 17 reduces edge by ~0.2% to 0.3% compared with hitting soft 17.
- Doubling after split: DAS lowers edge by ~0.20% to 0.30%; availability depends on table.
- Re-splitting Aces: allowing aggressive Ace re-splits boosts player edge by roughly 0.10% to 0.30% depending on overall rules.
- Late surrender: option to surrender after initial two cards reduces edge by around 0.08% to 0.20%.
Practical steps: before seated, check rule set; favor S17; DAS; late surrender; note deck count; verify payout on natural; avoid tables with 6:5 payout or H17 rule.
Bankroll Management for 21-Card Table

- Loss ceiling per session: 6% of funds; upon reaching, halt play for this session.
- Win target: 4% of funds; reach target, halt; resume after next budget refresh.
- Risk per hand: 0.5–2% of funds; adapt unit size as funds change; monitor volatility during runs.
Tracking & Table Selection
- Log: date, starting funds, ending funds, profit in units; compute ROI per session.
- Table rule set: favor S17, DAS, late surrender; prefer single-deck options when available; verify payouts before seating.
Q&A:
What is the goal of blackjack and how do you win a hand?
The aim is to have a total as close to 21 as possible without going over. You play against the dealer, not against other players. A hand wins by beating the dealer’s final total or by getting a blackjack on the first two cards (an Ace plus a 10-value card), which usually pays 3:2. If you and the dealer both reach 21, the higher total wins; if totals are equal, it’s a push and your bet is returned. If you go over 21, you bust and lose the bet. The dealer also busts if their total exceeds 21.
How are card values determined in blackjack?
Cards 2 through 10 are worth their face value. Face cards (Jack, Queen, King) count as 10. An Ace can count as 11 or 1, whichever keeps your total from busting and gives you the best chance to reach 21. This flexibility with the Ace creates soft totals, which let you adjust your hand when you draw another card. For example, an Ace with a 6 can be a soft 17 (either 7 or 17 depending on your next card).
What actions can you take on a hand and how does each one work?
Common choices are: Hit (take another card to improve your total), Stand (keep your current total and end your turn), Double Down (double your bet, receive one more card, and then stand), Split (when you have a pair, you split into two hands and play them separately, often with a second bet), and Surrender (forfeit half your bet to end the hand if the option is offered). Insurance is a separate side bet offered when the dealer shows an Ace; it pays 2:1 if the dealer has blackjack, but it is usually not favorable for the player.
What is basic strategy and how can beginners use it to improve odds?
Basic strategy is a set of rules that tells you the best move for every combination of your hand and the dealer’s visible upcard. It separates decisions by hand type: hard totals (no usable Ace), soft totals (a usable Ace), and pairs. Following a standard strategy chart helps you decide when to hit, stand, double down, or split. A few practical tips: always split Aces and Eights; avoid splitting tens or fives; use doubling when the dealer shows a weak upcard for strong hands; and consider surrender if allowed when your hand is weak against a strong upcard. Keep in mind that house rules vary, so adjust to the table you’re at.
