A Guide to Essential Casino Terms

Welcome to the world of casinos, where the chips are stacked, the dice are rolled, and the thrill of the game is all around you. Understanding the unique casino language can make all the difference in your experience, regardless of your skill level. 

From the basics of betting and house edge to the more advanced strategies of card counting and the Martingale system, this guide will take you on a journey through essential casino terms. 

Basic Gambling Terms

Let’s start with the basics because you’re bound to come across the following terms, no matter if you play brick-and-mortar or online casinos

House Edge

The house edge is the casino’s statistical advantage over the player in a given game. It represents the percentage of each wager that the casino expects to win in the long run.


This term can be described as the heartbeat of the casino floor. The sound of chips clacking, dice rolling, and card shuffling all constitute the rhythm of the action. And with every turn, every roll, and every deal, the excitement rises until someone hits the jackpot.


In the context of casinos, a wager refers to the act of placing a bet on the outcome of a game or event.


Bet is one of the most common terms in casino lingo. It refers to a single wager in a game. It also means risking or gambling a specific amount of money because the outcome of the game is unknown. 


The payout is the magical moment when the stars align and you hear the sweet sound of coins clanging together as the machine spits out your winnings. It’s a beautiful thing, really.


A bankroll refers to the funds available for betting purposes. Players should practice good bankroll management to avoid losing their money fast. 


A casino game’s jackpot is the top prize that a lucky player wins. Jackpots can be set amounts or progressive, which means they increase until someone finally wins. It’s the grand prize, the pot of gold at the end of the rainbow, the holy grail of gambling. Will you be lucky enough to catch it?


In casino terminology, chips are little round tokens that represent cash. Players use them to place wagers and cash out winnings. Chips come in all shapes, sizes, and colors, and they have a specific weight to them. Moreover, if you win big, you get to experience the joy of scooping up a pile of chips and feeling like a high roller.


A dealer is a casino staff member who controls the game and deals cards or spins the wheel. They’re calm, cool, and collected and have eyes in the back of their head (or so it seems). Just don’t let their soothing voice and friendly smile fool you—they’re after your money.


The croupier is like the fancier, more sophisticated cousin of the dealer. They’re the ones you’ll find at high roller tables, wearing a tuxedo and looking sharp. They exude confidence and class, and they’re there to make you feel like a VIP.

House Rules

All casino games are played according to a certain set of rules known as “house rules.” This gambling slang refers to the rules that everyone has to play by to ensure fairness and consistency. Different casinos and games may have different regulations.


A casino may extend credit to a player in the form of a marker. When money is no longer an option, players can use a marker to keep playing. It’s the casino’s way of saying, “We trust you (to a certain extent).” It’s a convenient way to keep playing when you’re running low on cash, but beware—it’s still real money that you’ll have to pay back.

Pit Boss

A pit boss is a casino employee who manages several table games in a specific area of the casino. They oversee everything that’s going on, from the dealers and players to the security team. They’re the ones you want to impress if you’re hoping to score some free drinks or other perks.


In a casino game, a shoe is a container used to carry several decks of cards. During the game, the dealer or croupier removes cards from the shoe and deals them to the players.


Surrendering in gambling terminology is like saying, “I’m waving the white flag.” It’s a way for players to cut their losses and salvage some of their money. Think of it as a strategic retreat because sometimes it’s better to live to fight another day.


It’s that feeling of frustration and desperation that can set in when you’re on a losing streak. It’s the moment when you start making irrational bets and taking unnecessary risks. Tilt can be a player’s worst enemy, but it can also be a wake-up call to take a break.

Blackjack Terms

Let’s shuffle the cards and dive into the world of blackjack terminology.


Splitting is an option that’s available when a player is dealt a pair of cards with the same rank, such as two 7s. The player can choose to split the cards into two separate hands, with each hand having its own bet. It’s a way to increase the chances of winning and turn a losing hand into a winning one.


In casino lingo, “paint” refers to any card with a picture on it, i.e., king, queen, or jack. This term is often used in blackjack. For instance, if a dealer tells you that you’ve got “paint,” it means you’ve been dealt a face card.

Double Down

Doubling down is available when a player is certain that they have a strong hand. The player can choose to double their original bet and receive only one additional card. It’s a way to maximize the potential payout and turn a good hand into a great one.

Craps Terms

Craps is a high-energy, fast-paced game of chance that has become a common game in many casinos around the world, especially American, so let’s go over some key terms.


You have to roll the exact pair of numbers to get a hardway combination. That means betting on the 4, 6, 8, or 10 as a pair, such as two 2s or two 5s, which is considered “hard.” When they’re not rolled as a pair, they’re considered “easy.” The goal is to bet that the dice will land “hard” before they land “easy” or before a 7 is rolled. 

Big 6 and Big 8

In craps, it’s another term for bets placed on the 6 or 8 to be rolled before a 7. While they have a higher payout than a bet on the 6 or 8, they also have a higher house edge and are considered a sucker bet by more experienced craps players.

Poker Slang

Are you looking to brush up on your poker vocabulary and understand the casino talk used in the game? Let’s go over some of the most common ones.


Ante is the price of admission to the poker party. Just like a VIP ticket to your favorite concert, the ante gets you a seat at the table and a shot at the big prizes.


Bluffing in poker is like being a master of disguise! It’s a strategy that involves making a bet or a raise with a weak hand in an attempt to manipulate your opponents into thinking that you have a strong hand. It’s a way to gain an advantage over your opponents and win the pot even when you don’t have the best cards.


Nuts is the best possible hand at any given moment in a particular game. Knowing that you have the nuts can give you a significant advantage in the game, as it means that you can’t be beaten. It’s a rare accomplishment that every poker player dreams of.


In gaming terminology, rake is the percentage of the pot that the casino takes as a fee for hosting the game. The rake can vary depending on the stakes and the casino, but it’s typically around 5% of the pot. While the rake can seem like a nuisance to players, it’s a necessary part of the game that helps to keep the casino in business.


The flop is the first three community cards that are dealt face up in the middle of the table in games like Texas hold’em. The flop is a critical point in the game, as it gives players a glimpse of the potential strength of their hand and helps them make strategic decisions about whether to fold or continue playing.


A fish, in poker, refers to an inexperienced player who often makes mistakes and loses money. More experienced players might look for “fish” at the table as an opportunity to win more pots.


A “shark” in poker is a highly skilled player who preys on less experienced or weaker players, much like a shark in the ocean. These players often have a deep understanding of the game and are able to read their opponents well.

Scatter symbols are symbols that can appear anywhere on the reels and pay out regardless of whether they’re on a payline or not. They’re like the little jokers in the deck, adding a bit of excitement and unpredictability to the game.

Wild Symbols

Progressive Jackpots

A progressive jackpot continues to grow as more players place bets, often reaching astronomical sums of money. They’re the ultimate goal for every slot machine player, and the chance to hit one is like winning the lottery.

High Roller

Kelly Criterion

It’s a mathematical strategy that helps players determine the optimal amount to bet based on the perceived advantage and potential payout. It’s a way to minimize risk while maximizing potential winnings.

Random Number Generator

A random number generator, or RNG, is a computer program that ensures that the outcomes of games are random and fair. It’s like the invisible hand that guides the spinning of the slot machine reels and the shuffling of the deck.

The odds of success are rather low because it’s a challenging draw. 


A George is the ideal player from the dealer’s point of view. This term refers to a player who tips well and consistently. So, if you want to be popular among the casino staff, try being a George.
