Blackjack Strategy Chart Generator

You cannot rely on a single universal blackjack chart. Basic strategy depends on the table rules: the number of decks, whether the dealer hits or stands on soft 17, and whether double after split is allowed. The right blackjack chart for a 6-deck S17 DAS table is not the same as the right chart for a single-deck H17 no-DAS table — and using the wrong one costs real money over time.

This generator builds the correct blackjack basic strategy chart for the rules you choose. The default view shows the most common Vegas/Atlantic City setup (4-8 decks, S17, DAS allowed). Change any rule and all three charts — hard totals, soft totals and pairs — update instantly. The result is print-friendly so you can take a small printed cheat sheet to the table.

How to Read the Blackjack Strategy Chart

Each chart cell tells you the mathematically optimal play for one specific situation: your hand against the dealer’s upcard. The notation:

• H — Hit. Take another card.
• S — Stand. End your turn.
• D — Double down. Double your bet and take exactly one card. If doubling is not allowed (already split, or table restriction), Hit instead.
• Ds — Double if allowed, otherwise Stand. Used on some soft hands.
• P — Split the pair into two hands.

The dealer upcard runs across the top (2 through Ace). Your hand runs down the side. Read across the row, find the dealer card, take the action shown.

Basic strategy is the mathematically correct play before any card counting. It minimizes the house edge to roughly 0.4-0.6% on a typical 6-deck S17 DAS game. It does not flip the odds — the casino still has an edge. To gain a player edge, you must add card counting on top of basic strategy. See the Blackjack Card Counting Calculator for the next step.

Which Rules Change Basic Strategy?

Three rules meaningfully change the basic strategy chart. A fourth common rule (3:2 vs 6:5 blackjack payout) does not change strategy decisions — it just changes the house edge. Avoid 6:5 tables regardless of strategy.

Surrender (typically Late Surrender against 9, 10 or Ace) is another rule that alters a few cells, mainly in the 14-16 range against high dealer cards. This generator does not include a surrender toggle — for surrender-aware index plays, use the Blackjack Deviations Calculator, which covers the Fab 4 surrender deviations alongside the Illustrious 18.

Hard Totals, Soft Totals and Pair Splitting

The strategy chart is split into three sections because each hand type has different decision logic.

Hard Totals

A hard total is any hand without an Ace, or with an Ace counted as 1 (because counting it as 11 would bust). Examples: 10+5 = hard 15, A+5+10 = hard 16. Hard totals are the most common hand type and the most rule-dependent for doubling decisions.

Key cells:

• 11 vs Ace: Double in single-deck and H17 multi-deck. Hit in S17 multi-deck.
• 9 vs 2: Double in single-deck. Hit in multi-deck.
• 12 vs 2 and 12 vs 3: Hit, even though it feels safer to stand. Dealer’s 2 or 3 makes 17+ more often than busting.
• 16 vs 10: Hit if no surrender. The worst hand in blackjack — both options lose more than half the time.

Soft Totals

A soft total is any hand with an Ace counted as 11. Examples: A+6 = soft 17, A+7 = soft 18. Soft totals cannot bust on the next hit because the Ace can drop to 1, which makes them ideal for aggressive doubling against weak dealer cards.

Key cells:

• A,8 (soft 19) vs 6 H17: Double if allowed, otherwise Stand. The classic H17-only Ds cell.
• A,7 (soft 18): The most rule-sensitive soft hand. Stand on 2/7/8, Double on 3-6, Hit on 9/10/A under S17.
• A,2-A,5: Double only on dealer 4-6 (or 5-6 for the lowest soft hands). Otherwise Hit.

Pairs

Splitting turns a pair into two starting hands. The decision depends heavily on whether DAS is allowed, because doubling on the post-split hands changes the value of splitting itself.

Key cells:

• A,A and 8,8: Always split, every rule set. Two separate good (or recoverable) hands beat one bad combined hand.
• 10,10: Never split. 20 is too strong to break apart.
• 4,4: Split only against dealer 5 or 6 with DAS allowed. Otherwise Hit.
• 5,5: Treat as a hard 10 — Double vs 2-9, Hit vs 10/A. Splitting 5,5 is one of the worst plays in blackjack.
• 2,2 / 3,3 / 6,6: Split more pairs with DAS than without DAS.

Printable Blackjack Strategy Chart

The generator includes a Print Chart button. Clicking it opens your browser’s print dialog and lays out the three tables (Hard, Soft, Pairs) in a clean, color-coded format that fits on a single page. The rule selectors and notes are hidden in the print view so the chart is ready to use.

Most casinos allow players to bring a small printed strategy card (about credit-card size) to the table. Phones and electronic devices are typically not allowed at live tables — under Nevada NRS 465.075 and similar laws elsewhere, using a device to assist play is a serious offense. A printed chart is the legal alternative and is widely accepted.

Practical tips for printing:

• Print at 100% scale, not “fit to page” — color contrast matters more than size.
• Generate the chart for your specific casino’s rules before printing. Vegas Strip is usually 6-deck H17 DAS; Atlantic City is 8-deck S17 DAS; Reno and downtown Vegas often use S17 with deeper penetration.
• Laminate the printout if you plan to use it across multiple sessions.

Strategy Chart Generator vs Hand Calculator

This page and the Blackjack Basic Strategy Calculator answer different questions, even though both rely on the same underlying basic strategy math:

• Strategy Chart Generator (this page): Builds the entire chart for a rule set. Use this when you want to study the full strategy, compare rule sets side-by-side, or print a cheat sheet for the table. Output is three full tables.
• Basic Strategy Calculator: Answers a single hand question. You input one player hand and one dealer upcard, and it returns the correct play with an explanation. Use this when you have a specific hand to check, not the whole chart.

For card counting deviations on top of basic strategy (the Illustrious 18 and Fab 4 plays), see the Blackjack Deviations Calculator. For the count itself and recognition speed, use the Blackjack Card Counting Calculator.

Common Rule Profiles by Region

If you are not sure which rules your local casino uses, these regional profiles cover most cases:

The default chart in the generator (4-8 decks, S17, DAS) is also the safest fallback if you don’t know the exact rules.
