BLACKJACK BASIC STRATEGY CHART 2026

Blackjack basic strategy is a mathematically optimal set of decisions for every hand combination — when to hit, stand, double down, split, or surrender based on your cards and the dealer's upcard. Using correct basic strategy reduces the house edge from 2–4% to approximately 0.5%. The decisions are fixed and can be memorised from a strategy chart, which is legal to use at most casinos.

Quick Reference: Strategy Summary

Basic Rules of Blackjack

Blackjack is played against the dealer, not other players. The objective is to build a hand value closer to 21 than the dealer without going over.

Card values: numbered cards (2–10) are worth their face value; Jack, Queen and King are worth 10; Ace is worth 1 or 11, whichever benefits the hand. A hand containing an Ace counted as 11 is called a "soft" hand (it cannot bust on the next card).

Gameplay: you receive two cards face-up; the dealer receives one face-up and one face-down. You then choose to hit (take a card), stand (end your turn), double down (double your bet and take exactly one more card), split (separate a pair into two hands), or surrender (forfeit half your bet and end the hand). A natural blackjack — Ace plus any 10-value card — pays 3:2 at standard tables. Avoid 6:5 tables entirely.

Blackjack Basic Strategy Chart

The full strategy chart below applies to 4–8 deck games where the dealer stands on soft 17 (S17) — the most common online blackjack rules. Print it or keep it open while you play. Using it is legal at every online casino.

Hit or Stand

The core principle: always assume the dealer's hidden card is a 10-value card (there are more 10-value cards in the deck than any other single value). This means when the dealer shows a 6, you treat their hidden card as a 10 — giving them 16, which means they must hit and have a high chance of busting.

Stand on hard 17 or higher — always. Stand on hard 12–16 when the dealer shows 2–6 (let the dealer bust). Hit hard 12–16 when the dealer shows 7 through Ace — the dealer is unlikely to bust, so you need to improve your hand.

Double Down

Doubling down means doubling your original bet and receiving exactly one more card. It is the highest-value play in blackjack when used correctly — and one of the most under-used by casual players.

• Double hard 11 against all dealer upcards except Ace (in some rules, double vs Ace too)
• Double hard 10 against dealer 2–9
• Double hard 9 against dealer 3–6
• Double soft 13–17 (Ace + 2 through 6) against dealer 4–6
• Double soft 18 (Ace + 7) against dealer 3–6

Split Pairs

Splitting turns one hand into two, each starting with one of your paired cards. You place an additional bet equal to your original.

• Always split: Aces and 8s — no exceptions
• Never split: 10-value pairs (you already have 20) or 5s (treat as hard 10)
• Split 9s against dealer 2–6 and 8–9; stand against 7, 10, or Ace
• Split 7s against dealer 2–7
• Split 2s and 3s against dealer 2–7
• Split 6s against dealer 2–6

Surrender

Surrender allows you to fold your hand and recover half your bet before play continues. It is the correct play when your winning probability falls below 25% — which means surrender saves money compared to playing out the hand.

Correct surrender decisions (where late surrender is available):

• Surrender hard 16 (not a pair of 8s) against dealer 9, 10, or Ace
• Surrender hard 15 against dealer 10

If the table does not offer surrender, skip these plays and hit instead.

Basic Strategy in 10 Essential Rules

If you cannot memorise the full chart, these ten rules cover the most common decisions and eliminate the worst mistakes:

1. Stand on hard 12–16 when the dealer shows 2–6 — let the dealer bust
2. Hit hard 12–16 when the dealer shows 7 or higher
3. Always stand on hard 17 or higher
4. Always split Aces and 8s
5. Never split 10-value cards or 5s
6. Double down on hard 11 against dealer 2–10
7. Double down on hard 10 against dealer 2–9
8. Surrender hard 16 against dealer 9, 10, or Ace
9. Never take insurance — it carries a house edge of approximately 7.4%
10. Only play 3:2 blackjack — 6:5 payout tables add 1.4% to the house edge

Common Blackjack Mistakes

Free Bet Blackjack: Rules and Strategy

Free Bet Blackjack is a casino variant developed by Shuffle Master (now Scientific Games) where the house funds your double-down and split bets at no cost to you — you keep the winnings but lose nothing extra if those bets lose.

The trade-off: if the dealer busts on exactly 22, all non-busted player hands push (tie) rather than win. This rule takes back most of the value from the free doubles and splits.

Free Bet Blackjack Rules

• Free doubles: Hard 9, 10, and 11 — the house places the second chip
• Free splits: All pairs except 10-value cards — each split hand gets a free token
• Re-splits: Allowed up to 4 hands (including Aces)
• Push 22: Dealer busts on 22 → all non-busted hands push instead of winning
• Standard blackjack pays: 3:2

RTP with correct strategy is approximately 98.4% — slightly lower than standard blackjack (99.5%) but the free bets make the game feel more action-packed and reduce variance on individual session outcomes.

Strategy Adjustments for Free Bet Blackjack

• Take all free doubles and free splits — they cost nothing to take
• Stand on hard 12 vs. dealer 2 and 3 (push 22 makes busting less punishing, but staying safe still applies)
• The push-22 rule slightly reduces the value of standing on stiff hands vs. low dealer upcards — but the standard chart remains a close approximation

Blackjack House Edge by Rule Variant

The biggest single factor is payout: a 6:5 blackjack table adds over 1.3% to the house edge versus a 3:2 table. This alone makes many blackjack variants unplayable from a pure odds standpoint. Always verify the payout ratio before sitting down.
