Blackjack Lingo

In this article on Blackjack lingo, we take a look at all the betting terminology that you should familiarise yourself with to play blackjack. We have all the blackjack terms that you will need to know, so have a read through to find out all the information you need to know.


86’d: Getting told by a casino that you are being trespassed from their property. Usually, this is the direct consequence of using your brain to make wise decisions with your money. Sometimes they try and get you to sign paperwork.


Ace: In Blackjack, an Ace card (A) can be counted as both a value of 1, or 11.

Action: The amount of money that’s been bet. Can refer to an aggregate of the total amounts of bets made over a certain period of time, or it can refer to the amount in play on a particular wager. Usually said by a host or pitboss, wearing a ROLEX and expensive (looking) suit. “That guy’s giving us good action.”

Advantage: The statistically theoretical edge one side has over the other, usually expressed as a percentage of the wager. Usually the casino has the advantage, but card counting can give the player the advantage.

Advantage Player: A gambler who uses strategy to gain a mathematical advantage over the casino.


Back Counting: Counting cards from behind the table as a spectator. Back counting is a great tactic to avoid negative counts. Sometimes referred to as “wonging.”

Back Off: When the casino asks you not to play blackjack anymore. This is usually delivered in the form of a statement like “your game is to strong for us” and sometimes delivered with the good news that “you are welcome to play any other game, just not 21.” Not to be confused with being 86’d.

Balanced Count: A card counting system in which the sum of the negative cards is equal to the sum of positive cards. If the running count at the end of a full deck equals zero, it is a balanced count.

Bankroll: The amount of funds available for wagering. Sometimes refers to the total amount of money available to gamble with, but can also refer to the amount available in a given playing session or for a given time period.

Barred: Permanently prohibited from a property. Used by card counters for when they have been 86’d from a casino, though it can apply to other properties. I.e. “I was eating so much food they had to bar me from the buffet.”


Basic Strategy: The optimal playing strategy for blackjack. The easiest way to find out if someone knows “basic” is to ask them what to do with a soft 18. If they tell you anything that is not on the chart or use words like “sometimes”, “usually”, or “depends” you know they are a fraud.

Bet Spread: The amount of the maximum and minimum bets a player is making during a blackjack playing session. A 1-5 bet spread means that the player is betting a minimum of 1 unit per hand and a maximum of 5 units per hand. When counting, the larger the spread the more money you expect to make.

Card Counting: A strategy for establishing an edge in the game of Blackjack by tracking the ratio of high cards to low cards that have already been played. A card counter raises his bet when the deck offers favorable odds to the player, and lowers his bet when the deck offers less-than-favorable odds to the player. There are multiple card counting systems with varying degrees of efficiency.

As long as you pay your taxes, there’s nothing to worry about.
