Basic strategy meaning: in blackjack, basic strategy is the set of plays that loses the least on average for every combination of your hand and the dealer’s upcard. It tells you when to hit, stand, double, split or surrender. It lowers the house edge, but it never removes it, so blackjack still costs money over time.
Basic strategy is a chart of the best play for each player hand against each dealer upcard.
It is worked out by computer analysis of the game’s rules, not by hunches or streaks.
Following it lowers the house edge; it doesn’t turn blackjack into a winning game.
Charts change with rules such as deck count, soft 17 and doubling limits, so match the chart to the game.

Basic strategy meaning: the best play for every hand
In our casino glossary, basic strategy is the closest thing blackjack has to a rulebook for players. For each starting hand you can hold, and each card the dealer can show, there is one choice with the best long-run result. List them all in a grid and you have a basic strategy chart.
“Basic” doesn’t mean simple; it means the strategy uses only the information everyone can see: your cards and the dealer’s upcard. It ignores cards dealt in earlier rounds. Strategies that track those cards are card counting, which doesn’t work in online RNG games.
How to read a basic strategy chart
Find your hand type: a pair, a soft hand (with an ace counted as 11) or a hard hand.
Find the row for your total or pair.
Find the column for the dealer’s upcard, from 2 through ace.
Read the letter where they cross: usually H (hit), S (stand), D (double), P (split) or R (surrender).
If the chart says double or surrender and the game won’t allow it, use the fallback the chart gives, usually hit.
Pairs come first because the split decision is made before anything else; then soft hands; then hard. Our soft hand and hard hand entries explain why the same total is played differently with and without an ace.

Where basic strategy comes from and why the chart changes
Charts are produced by computer analysis: every possible decision is played out over vast numbers of simulated hands, and the option with the best average result wins its cell. The answer depends on the rules, so changes such as the number of decks, whether the dealer hits soft 17, and whether you can double after a split each shift a few cells.
That is why one chart doesn’t fit every game. RTG runs several blackjack variants, including Suit ’Em Up Blackjack, which SlotCatalog lists with the dealer hitting soft 17 and blackjack paying 3:2, and six-deck Super 21. Use a chart built for the rules on the game’s help screen.
What basic strategy does to the house edge, in dollars
Third-party RTP figures for RTG blackjack games give a sense of the cost. PokerListings lists Super 21 at 99.6%, and GamesHub’s RTG list (opens in a new tab) gives Suit ’Em Up up to 99.51%. Expected loss is total stakes × house edge, so the cost stays small but never reaches zero.

The last row shows how side bets can push the cost up sharply. Playing hunches instead of the chart raises the edge too, by an amount that depends on the mistakes. For more on the arithmetic, see house edge explained and the question what is the house edge on blackjack.
What basic strategy can’t do
It doesn’t guarantee a winning session; short-term results swing both ways.
It doesn’t tell you how much to bet. Betting systems such as the Martingale don’t change the edge and can drive stakes up fast.
It doesn’t make blackjack a way to earn money; treat losses as the cost of entertainment.
Pair the chart with a budget from our bankroll management guide. If you notice yourself chasing losses, the National Problem Gambling Helpline, 1-800-MY-RESET (1-800-697-3738), offers free, confidential call, text and chat support.

Frequently asked questions
What does basic strategy mean in blackjack?
Basic strategy means the set of decisions that gives the best average result for every pairing of your hand and the dealer’s upcard. It covers hitting, standing, doubling, splitting and surrender, and it always says to decline insurance. It is usually shown as a color-coded chart. Our blackjack basic strategy guide has the full chart.
Does basic strategy beat the house?
No, basic strategy reduces the house edge but doesn’t remove it. Third-party listings put the RTP of RTG blackjack games such as Super 21 at 99.6%, which still means an average cost of $4 per $1,000 staked. Short sessions can end in profit, but the long-run expectation is a loss. See our house edge entry for how that cost works.
Is basic strategy the same for every blackjack game?
No, the chart changes with the rules. The number of decks, whether the dealer hits soft 17, doubling limits and surrender all move a few decisions. Variants with special rules may need their own chart. Read the game’s help screen first, then match it to a chart; our online blackjack page covers the standard RTG version.
Can you use a basic strategy chart online?
Yes, you can keep a chart open while you play online blackjack, since the game runs at your pace and nobody watches your screen. Many players learn the pairs and soft hands first because those are the least intuitive. Practicing in a free demo mode, where offered, lets you learn without risking money.
Is basic strategy the same as card counting?
No. Basic strategy uses only your cards and the dealer’s upcard; card counting also tracks cards from earlier rounds. Counting needs a deck that isn’t reshuffled every hand, so it doesn’t work in online RNG blackjack. Basic strategy works the same in every hand. Our card counting entry covers the history and theory.
What is the most important basic strategy rule?
No single rule matters most, but a few cover the costliest mistakes: always split aces and 8s, never split 10s, double on 11 against most dealer cards, and never take insurance. Standing on stiff hands against a dealer 7 or higher is a common error. Our split and insurance entries explain these in dollars.
Should you hit or stand on 16 against a dealer 10 in basic strategy?
Basic strategy says to hit hard 16 against a dealer 10, or to surrender it if the game allows surrender. Both choices lose money on average, because 16 is one of the weakest hands in blackjack, but standing loses more often against a strong upcard. The same row of a typical multi-deck chart says to hit hard 13 to 16 against any dealer 7 through ace. It feels wrong to many players, which is why it's one of the most common mistakes. Our hard hand entry and surrender entry explain the reasoning.
Does basic strategy work in Super 21 blackjack?
A basic strategy approach works in Super 21, but a standard chart may not fit it exactly, because the game's rules differ from regular blackjack. PokerListings lists RTG's Super 21 as a six-deck game with a 99.6% RTP, which means an average cost of about $4 per $1,000 staked with correct play. Other rule details weren't published in our sources, so read the game's help screen and use a chart built for those rules where you can find one. Our Super 21 page covers the game, and how to play blackjack explains the standard rules it changes.
Is the basic strategy chart different when the dealer hits soft 17?
Yes, a few cells on the chart change when the dealer hits soft 17 rather than standing on it. The rule changes how often the dealer improves a soft total, so the best play shifts in a handful of cells, mostly doubles and surrenders. SlotCatalog lists RTG's Suit 'Em Up Blackjack with the dealer hitting soft 17 and blackjack paying 3:2, so a chart labeled for 'dealer stands on soft 17' isn't the best match there. Check which rule the help screen shows before choosing a chart. Our soft hand entry and Suit 'Em Up Blackjack page explain the detail.
Is basic strategy any use for blackjack side bets?
No, basic strategy covers only the main hand and does nothing for side bets. Side bets such as Perfect Pairs or Suit 'Em Up's suited bonus are settled on your first cards before any decision is made, so the chart can't change their odds. GamesHub gives RTG's Blackjack + Perfect Pairs an RTP range of 95.9% to 99.59%, and at the low end, $2,000 of play costs about $82 on average against about $8 at 99.6%. Skipping side bets is one of the simplest ways to keep costs down. Our Blackjack Perfect Pairs page and what is Blackjack Perfect Pairs answer cover the bet.
Can I use basic strategy to clear a casino bonus on blackjack?
You can, but blackjack usually clears bonuses slowly or not at all. Silver Oak's terms set 60x on table games against 40x on slots, and SlotoCash's welcome terms exclude table games and void winnings from them. As a worked example, if 60x applied to a $200 balance, you'd need $12,000 of blackjack bets, which at about a 0.5% edge, close to third-party figures for RTG's Super 21 and Suit 'Em Up, would cost about $60 on average and take a long time. Always read the eligible-games list first. Our best bonus for blackjack page and game weighting entry explain the rules.
Is online blackjack with basic strategy legal in Connecticut?
Yes, online casino games, including blackjack, are legal in Connecticut at sites licensed by the state, which authorized them in legislation signed in May 2021, Public Act 21-23. The Department of Consumer Protection's Gaming Division regulates them. Using a strategy chart is simply how you play the game, and it isn't a legal question. Offshore casinos, including the partners on this page, hold no Connecticut license, so they sit outside the state's player protections. Our Connecticut online casinos hub and states with legal online casinos page explain the licensed options.
