The Only Real Limit Is the Total on Your Cards
You sit down, buy in, and the dealer slides two cards toward you. The question of how many hits you are allowed is less about a rulebook number and more about a hard mathematical ceiling. You can keep asking for cards until your hand total reaches 21 or goes over it. The moment the total passes 21, the hand is dead. That is the actual constraint, and it applies on every hit, every time, regardless of what the dealer is showing.
No casino table posts a sign that says "three hits maximum" or "five hits only." The limit is built into the arithmetic of the game. A hand of 2 and 3 totals 5. You could hit ten times in theory and still be alive if the cards keep coming small. In practice, the deck runs out of small cards quickly, and every hit carries the risk of drawing a ten-value card or a face card that pushes a soft total into a hard one or a hard total over the cliff.
What does change from table to table is whether you are allowed to hit after certain actions. Some rule sets let you hit after splitting aces; many do not. Some let you hit a hand you have already doubled; almost none do, because the double is a commitment. Those restrictions are printed in the table rules or shown on the layout itself, and they are the only place where a "hit allowed" or "hit not allowed" condition appears.
The Sequence of a Round, From Buy-In to Settlement
Understanding hits means understanding where they sit in the round. You buy in by placing cash on the felt; the dealer exchanges it for chips without touching your hand. You place a wager in the betting circle before any cards are dealt. The dealer gives each player two cards face up and takes two for themselves, one up and one down. If the dealer's upcard is an ace, some tables offer insurance, a side bet on the dealer having a natural. That is a separate wager with its own math, and it is not a hit.
Play proceeds around the table. On your turn, you decide what to do with the two cards in front of you. Hit means you want another card. Stand means you are satisfied. Double down means you add a wager equal to your original bet and receive exactly one more card, after which your turn ends whether you like the card or not. Split means you have a pair and you separate it into two hands, each with its own bet and its own sequence of decisions.
After every player has acted, the dealer reveals the down card and plays their own hand according to a fixed rule that is printed on the table. Usually the dealer must hit on totals below a certain number and stand on totals at or above it. The dealer has no discretion. If the dealer busts, every remaining player hand wins. If the dealer makes a total, each hand is compared to the dealer's total, and the higher one wins. A push returns the wager.
What Each Decision Point Means
Most new players treat hitting as the default and standing as the thing you do when you are scared. That is backwards. The decision is about the dealer's upcard, not about your optimism. You are not trying to get close to 21; you are trying to beat the total the dealer is most likely to make, or to survive long enough for the dealer to bust.
A hand of 16 against a dealer's 6 looks weak, but the correct play in basic strategy is often to stand. The dealer has a high chance of busting from that upcard, so hitting risks taking the bust yourself when you did not need to. A hand of 12 against a dealer's 2 is the opposite: standing is dangerous because the dealer has room to build a strong hand, and hitting is the less bad option even though it feels risky. The chart that tells you which action to take is derived from the exact rule set at the table. Change the number of decks, change whether the dealer stands on soft 17, change whether doubling after splitting is allowed, and the chart changes. A chart printed for one rule set is not automatically correct for another.
| Decision | What You Do | What It Commits You To |
|---|---|---|
| Hit | Take another card | You may act again unless the total reaches 21 or busts |
| Stand | Keep your current total | Your hand is final for the round |
| Double down | Add a wager equal to your original and take one card | Your turn ends after that single card |
| Split | Separate a pair into two hands | Each hand gets its own bet and its own decisions |
| Surrender (where offered) | Give up the hand and forfeit a portion of the wager | The hand ends immediately |
Surrender does not appear at every table. Where it does, it is a way to cut your loss on a hand that is very likely to lose, and it is not a hit at all. The table rules state whether it is available and in what form.
The Main Bets and How Their Edges Differ
Blackjack is unusual among table games because the player's decisions affect the expected loss on the hand. The base wager carries a house edge that depends on the rule set, and published basic-strategy charts exist precisely because playing the hand well reduces that edge compared to guessing. That does not mean the player gains an advantage. It means the built-in mathematical advantage the operator holds is smaller when the player makes the choices that the chart specifies for that rule set.
Side bets are a different animal. Insurance, when the dealer shows an ace, is a wager that the dealer has a ten-value card underneath. Perfect pairs, 21+3, and similar side bets pay more when they hit, but they carry materially different house edges from the main game. The table below compares the structural differences, not specific percentages, because those percentages are printed in the game's information panel or the table's rule card and vary by rule set.
| Bet Type | What It Pays On | How It Behaves |
|---|---|---|
| Main wager | Beating the dealer's total without busting | Edge depends on rule set and player decisions; the only bet where decisions change the expected loss |
| Insurance | Dealer having a natural when showing an ace | Separate wager; resolved before the main hand plays out |
| Side bets (e.g., pairs, 21+3) | Specific card combinations on the first cards | Fixed payouts; house edge is set by the pay table and does not change with player decisions |
If you want to know the exact edge on any of these bets at your table, the game information panel or the table's printed rules carry the figures. The rule set in use determines them, and two tables in the same venue can differ.
Procedural Mistakes That Cost New Players
The first mistake is touching the cards. In most shoe-dealt games, the cards are dealt face up and you never touch them. In pitch games where cards are dealt face down, you may touch them with one hand only, and you keep them above the table in view of the camera. Reaching for a hit card that the dealer has not offered, or moving your cards out of sight, will get the hand paused and the floor called over. The hand is not void, but the procedure is broken and the pit will watch you more closely.
The second mistake is signalling wrong. You do not say "hit me" and wave at the same time, because the camera records the hand signal, not the voice. The standard signal for a hit is a tap or a scratch on the felt behind your cards. For a stand, you wave your hand palm down over the cards. If you say one thing and signal another, the signal wins. Learn the signals before you sit down; the dealer will tell you if you ask, and asking is free.
The third mistake is hitting a hand that the chart says to stand, not because you disagree with the chart, but because you never looked at it. The chart is not a guarantee of winning the hand. It is a set of choices that minimises the expected loss under a specific rule set. Playing by feel instead of by chart does not change the built-in edge of the game; it just makes the expected loss larger than it needed to be. If you do not have a chart for the exact rule set at the table, the table's own printed rules tell you the parameters you need to find the right one.
FAQ
Can you hit after you double down?
No. A double down is a commitment: you add a wager equal to your original bet and receive exactly one card. Your turn ends after that card, even if the card is a small one and you would like another. Some rule sets allow doubling on certain totals only, and those conditions are printed on the table layout or the rule card.
Is there a minimum number of hits you must take?
No. You are never forced to hit. You can stand on any two-card total, including a very low one. Standing on a low total is usually a poor choice against a strong dealer upcard, but it is a legal play. The dealer's hand is the only one that follows a mandatory hitting rule, and that rule is fixed and printed on the table.
What happens if you hit and the card makes exactly 21?
The hand is complete. You do not get to keep hitting, because there is nothing to hit toward. A total of 21 stands automatically, and your turn passes to the next player. If the dealer also makes 21, the hand is a push and your wager is returned. A two-card 21 is a natural and pays differently from a 21 made with three or more cards, depending on the table's rules.
