Blackjack Terms: Complete A-to-Z Glossary
This reference glossary groups the most useful blackjack terms by category, so players at every level can quickly find what they need.
It covers the blackjack words used at the table, the actions that shape a hand, and the rule variations that can change how a game plays.
Gameplay Actions
Hit
A hit means asking for another card during a hand. It applies when your current total is not where you want it to be, but it also increases the chance of busting if the next card pushes you over 21.
Stand
Stand means you keep your current hand and take no more cards. It’s used when you’re satisfied with your total or when taking another card would carry too much risk.
Double Down
Double down means you place an additional bet and receive exactly one more card. It usually applies after your first two cards, and many tables restrict when you can use it depending on the hand value or house rules.
Split
Split applies when your first two cards are a pair, letting you turn them into two separate hands. A second stake is required for the new hand, so the decision changes both risk and potential return.
Surrender
Surrender in blackjack lets you give up your hand and recover half your bet. It’s only available in some blackjack variants and is most useful when the dealer’s upcard puts your hand in a weak position.
Bust
Bust means your hand goes over 21 and loses immediately. The dealer busts on the same rule, but players still need to finish their decisions before that result is settled.
Insurance
Insurance is a side bet offered when the dealer shows an ace. It’s a separate wager tied to the chance that the dealer has blackjack, paying 2 to 1 if they do.
Hand Types and Values
21
21 is the target total in blackjack and the highest value a hand can reach without busting. It’s also the name many players use for the game itself.
Blackjack or Natural
A blackjack or natural is a two-card total of 21, made with an ace and a 10-value card. It’s the strongest possible opening hand and is often paid at a higher rate than a standard win, typically 3 to 2.
Ace
An ace can count as 1 or 11, whichever helps the hand most. That flexibility makes it the most important card in the game, especially when it combines with a 10-value card to form a natural blackjack.
Face Cards
Face cards are the jack, queen, and king. Each counts as 10 in blackjack, which is why they are central to making 20s and blackjacks.
Hand
A hand is the set of cards a player or dealer holds in a given round. The value changes as cards are added, so every decision depends on the current total in front of you.
Hard Hand
A hard hand contains no ace counted as 11. It has a single fixed value, which makes it less flexible than a soft hand and more prone to busting when the total is already high.
Soft Hand
A soft hand contains an ace counted as 11. Because the ace can drop to 1 if needed, soft hands give the player more room to hit without busting.
Soft 17
Soft 17 is a hand totalling 17 with an ace counted as 11 – for example, ace-6. Some tables require the dealer to hit soft 17, while others require a stand. This rule affects the house edge and is worth checking before you sit down.
Stiff
A stiff hand is any total from 12 to 16. It’s the hardest range to play because one more card could easily push the hand over 21.
Pat Hand
A pat hand is a total strong enough to stand on, usually 17 to 21. Players typically stop drawing once they reach a pat hand because the risk of busting outweighs the possible gain.
Pair
A pair is any two cards of equal value, such as 8-8 or king-king. Pairs matter because they can be split into two separate hands, depending on table rules.
Five-Card Charlie
A five-card Charlie is a hand of five cards that hasn’t busted. In some blackjack variants, it’s treated as an automatic win or a strong result, but this rule is not universal.
Push
A push is a tie between the player and the dealer. The original bet is returned, with no win and no loss.
Table and Deck Terms
Dealer
The dealer deals the cards and acts as the house opponent in blackjack. Every player’s hand is compared against the dealer’s result, not against other players at the table.
Hole Card
The hole card is the dealer’s face-down card. It stays hidden until the dealer’s hand is resolved, making it a central source of tension during early decisions.
Upcard
The upcard is the dealer’s face-up card. It’s the key piece of information players use when deciding whether to hit, stand, split, or double.
Shoe
A shoe is the device that holds the cards before they are dealt. Multi-deck blackjack games deal from a shoe rather than from a single pack held in the dealer’s hand.
Cut Card
A cut card is a plastic card used to mark where the shoe will be cut before play resumes. It helps randomise the deal and signals roughly when the shoe is nearing the end.
Burn Card
A burn card is the top card removed and set aside after the shuffle. It prevents any advantage from knowledge of the first card in the shoe.
Box
A box is the designated area on the table where a player’s cards and chips are kept. It’s also a common way to refer to a player’s position at the table.
First Base
First base is the first seat to receive cards and is located to the dealer’s left. It’s the first position to act after the initial deal.
Anchor or Anchorman
Anchor – also called anchorman or third base – is the last seat to act before the dealer. Some players prefer this position because they see more of the table’s decisions before making their own.
Heads Up
Heads up means a one-player game against the dealer. It’s the simplest table format and removes the influence of other players’ choices.
Pontoon
Pontoon is a British blackjack variant with its own terminology and rules. It’s closely related to blackjack but is typically used to describe the British version rather than the standard casino game.
Betting and Bankroll Terms
Action
Action means the total amount wagered, either on a single hand or across a full session. Players also use it to describe the pace and level of betting at a table.
Bankroll
A bankroll is the money set aside for play before a session starts. Keeping it separate from everyday spending and setting clear limits helps you stay in control.
Bet Spread
Bet spread is the gap between a player’s smallest and largest wager. It shows how much a player varies their stake from hand to hand.
Buy-in
A buy-in is the amount placed to enter and start playing. Always check the table minimum before sitting down to make sure it fits your budget.
Chip Up
Chip up means increasing your wager from the previous round. Players do this when they want to raise their stake based on their read of the game.
Chip Down
Chip down means reducing your wager from the previous round. It’s a simple way to protect your bankroll during a difficult run.
Flat Betting
Flat betting means staking the same amount on every hand. It keeps risk more predictable than adjusting your bets from hand to hand.
Side Bet
A side bet is an extra wager placed alongside the main hand. It is separate from the core blackjack result and usually comes with its own odds and payout structure.
Win Rate
Win rate is the percentage of hands a player can expect to win over time. In blackjack, played with basic strategy, that figure is approximately 42.22%, with a push occurring around 8.48% of the time. It is not a short-term guarantee.
Rules and Strategy Terms
Basic Strategy
Basic strategy is the mathematically tested way to play each hand against each dealer’s upcard. It does not remove the house edge, but it helps players make the lowest-cost decision in common situations.
House Edge
House edge is the casino’s built-in mathematical advantage. In blackjack, it shifts with the rule set, deck count, and player decisions, which is why checking table rules before you play matters.
21+3
21+3 is one of many blackjack side bets based on your first two cards combined with the dealer’s upcard. It targets poker-style combinations, making it very different from the main blackjack hand.
D9
D9 means you can only double on hands totalling 9, 10, or 11. It narrows where double down is available and reduces player flexibility.
DA2
DA2 means you can double on any two cards. It’s a player-friendly rule that allows more freedom than the D9 restriction.
DAS or NDAS
DAS stands for double after split; NDAS means no double after split. This rule determines whether a split hand can be improved with an extra stake and one more card.
RSA or NRSA
RSA stands for resplitting aces; NRSA means no resplitting aces. Where resplitting is allowed, a split pair of aces can be split again if another ace appears.
Double Exposure
Double exposure is a blackjack variant in which both dealer cards are dealt face up. The extra information shifts strategy considerably, and the game usually compensates with adjusted payouts or tighter rules elsewhere.
Late Surrender
Late surrender allows a player to surrender only after the dealer has checked for blackjack. It’s a narrower form of surrender and is not available at every table.
Ace Poor or Ace Rich
Ace poor and ace rich are terms used when tracking how many aces remain in the shoe relative to expectation. An ace-rich shoe tends to be more favourable for strong opening hands; an ace-poor shoe less so.
Cold Deck
A cold deck is a shoe that appears to be producing weak results over a run of hands. It’s a player’s description of a bad run, not a formal game term.
Colour Up
Colour up means exchanging smaller chips for larger denominations before leaving the table. It’s standard etiquette and keeps the table organised.
True Count
True count is a card-counting measure that adjusts the running count for the number of decks still to be dealt. It gives a more accurate picture of deck composition than the raw count alone.
