Secret Casino Codes and Hand Signals: The Hidden Language of Casino Floors

Walk into any casino and you'll witness a carefully choreographed ballet of communication happening in plain sight—yet almost entirely invisible to the casual observer. Dealers tap the table in specific patterns. Pit bosses murmur coded phrases into hidden microphones. Security personnel exchange subtle glances. Every gesture, every phrase, every movement is part of an elaborate communication system developed over decades to keep games running honestly and operations flowing smoothly.

This hidden language serves a critical purpose: ensuring that every transaction is visible to the cameras overhead, that supervisors can communicate without alarming players, and that security can respond to threats without creating panic. The language of the casino floor is a fascinating blend of regulatory requirement, historical tradition, and practical necessity.

Blackjack: The Most Signal-Heavy Game

Blackjack has more standardized hand signals than any other casino game, and for good reason. The game involves player decisions that must be clearly communicated and documented for the surveillance teams watching from above. These signals aren't optional—they're required by gaming regulations in most jurisdictions.

Player Hand Signals

The Nevada Gaming Control Board mandates specific hand signals for blackjack to create an unambiguous record of player decisions. This requirement emerged from countless disputes where players claimed they said one thing and the dealer heard another. With hand signals, the cameras don't lie.

In shoe games (where cards are dealt face-up), the standard signals are:

• Hit: Tap or scratch the table behind your cards with your finger. Some players make a beckoning motion toward themselves.
• Stand: Wave your hand horizontally over your cards, palm down, as if saying "no more."
• Double Down: Place an additional bet next to (not on top of) your original wager and hold up one finger to indicate you want only one more card.
• Split: Place a second bet equal to your first next to the original wager and make a "V" with your index and middle fingers (the victory or peace sign).
• Surrender: Draw an imaginary line behind your bet with your finger (though this is rarely offered today and signals vary by casino).

In handheld or "pitch" games (where cards are dealt face-down), the signals differ because you're holding your cards:

• Hit: Scrape the corner of your cards against the felt toward yourself.
• Stand: Slide your cards under your chips without touching them.

Dealer Hand Signals

Dealers have their own required signals, designed to show surveillance that procedures are being followed correctly:

• Clapping out: When dealers leave a table or at specific intervals, they turn their palms up to show they're clean, then clap hands together, and finally turn palms down. This demonstrates they haven't palmed any chips.
• Pushing chips: Dealers push winning payouts toward players with an open palm, never grabbing or placing chips directly.
• Card exposure: When checking for blackjack with a 10-value upcard, dealers use specific peek devices or procedures that prevent them from signaling the hole card—a safeguard against the kinds of collusion detailed in our article on dealer tells and mistakes.
• Drop box procedures: When inserting currency into the drop box, dealers spread bills face-up on the table, announce the amount, then use a specific folding technique before dropping them—all while keeping hands visible.

Craps: The Language of the Dice

Craps is perhaps the most verbally complex game in the casino, with dealers (called "boxmen," "stickmen," and "base dealers") using a vocabulary that can sound like a foreign language to newcomers. The Encyclopaedia Britannica notes that craps terminology evolved from 19th-century street gambling and riverboat casinos, acquiring colorful phrases that persisted into the modern era.

The Stickman's Calls

The stickman (who controls the dice with a curved stick) makes specific calls throughout the game:

• "Coming out!" — Signals the start of a new game, the come-out roll.
• "Seven out, line away!" — The shooter has rolled a 7 after establishing a point, meaning pass line bets lose.
• "Winner winner!" or "Winner on the pass line!" — Pass line bets have won.
• "Craps!" — A 2, 3, or 12 has been rolled on the come-out.
• "Yo-leven!" — An 11 has been rolled. The "yo" prefix distinguishes it from 7, which sounds similar in a noisy casino.
• "Snake eyes!" — A pair of ones (craps on come-out roll).
• "Boxcars!" or "Midnight!" — A pair of sixes.
• "Hard eight!" or "Easy eight!" — Whether the 8 was made with matching dice (4-4) or not (6-2, 5-3).

Dealer Hand Signals at Craps

The craps crew uses specific hand signals to communicate across the large table:

• Dice passes: When dice leave the table or must be replaced, the boxman inspects them and signals to the floor supervisor by holding up fingers to indicate how many dice are being returned to play.
• Payment signals: Base dealers tap the table near bet positions to confirm placements and payouts for surveillance.
• Off/On signals: When odds bets are "off" during come-out rolls, dealers place a small "off" button on them—a visual signal that protects both player and casino from disputes.

Roulette: Colorful Communication

Roulette has its own signaling system, focused primarily on identifying bets and managing the chaos of a crowded table where multiple players may be reaching for the same betting areas.

The Dealer's Procedures

Roulette dealers (or croupiers, using the traditional term) follow specific procedures:

• "No more bets" is called and accompanied by a hand wave over the layout as the ball slows, preventing any late betting.
• The dolly: A marker called a dolly is placed on the winning number before any chips are collected, creating a clear visual record of the result.
• Color-up: Each player is assigned colored chips unique to that table, and when leaving, they must exchange these for regular casino chips—a process done with specific spreading and counting procedures visible to cameras.

The history of players trying to exploit roulette through various means—from timing devices to wheel bias analysis—is covered in our article on roulette wheel bias hunters.

Pit Boss Codes and Floor Communication

Perhaps the most intriguing aspect of casino communication is the coded language used by floor supervisors, pit bosses, and security. Much of this communication happens discreetly, designed to allow staff to discuss situations without alarming players or tipping off potential cheaters.

Common Verbal Codes

While casinos guard their specific codes carefully, former employees and industry publications have revealed some commonly used terms:

• "George" — A player who tips well. "He's a real George" means the player is generous with the dealers.
• "Stiff" — The opposite: a player who never tips, regardless of wins.
• "Steam" — A player who's showing signs of frustration or anger.
• "Railbird" — Someone watching games without playing, potentially scouting for opportunities.
• "Mechanic" — A skilled cheater who manipulates cards or dice.
• "Heat" — Increased scrutiny from surveillance or floor staff. As detailed in our article on card counting legality, skilled players often receive "heat" even when doing nothing illegal.
• "86'd" — Banned from the property. The origin of this term is disputed, but it's universal in the gaming industry.

Radio and Earpiece Communication

Modern casinos equip supervisory staff with nearly invisible earpieces connected to radio systems. These allow real-time communication with surveillance rooms and security teams. According to the UNLV International Gaming Institute, the shift to encrypted digital radio systems was driven partly by incidents where cheating teams used scanners to monitor casino communications.

Common radio codes include:

• 10-codes: Many casinos use variations of police 10-codes (10-4 for acknowledgment, etc.).
• Color codes: "Code Red" might indicate a medical emergency; "Code Blue" a security threat. Specific meanings vary by property.
• Location codes: Properties use zone designations that allow responders to locate incidents quickly without broadcasting obvious locations.

"When you hear 'attention surveillance, we have a possible 10-33 at pit 7,' that sounds like police procedure—and it's designed to. We want coordination without creating panic. The guest three feet away from a shoplifter shouldn't know anything's happening until it's handled." — Former Strip casino surveillance director, speaking at a security conference

The Rating System Language

Casinos use a sophisticated vocabulary to rate players for comp purposes—a system deeply connected to how casino hosts manage VIP relationships. This language communicates a player's value without the player necessarily understanding what's being said.

Rating Terminology

• "Theoretical" or "Theo" — The calculated mathematical expected win from a player based on hours played, average bet, and game house edge.
• "ADT" (Average Daily Theoretical) — A player's expected daily value to the casino.
• "Trip worth" — Total theoretical value of a player's entire visit.
• "Green player" or "Black player" — References to chip color indicating average bet size ($25 for green, $100 for black).
• "Premium player" or "Whale" — The highest tier of gambler, as detailed in our casino whales article.

Our comp value calculator demonstrates how casinos perform these calculations to determine what they'll offer in return for your play.

Security Alert Signals

When security issues arise, casino staff use subtle signals to communicate without creating disturbance. Former security professionals have described some common approaches:

Visual Cues

• Touching the ear: Often indicates staff is receiving or transmitting radio communication, alerting nearby colleagues that something's happening.
• Specific positions: Security personnel standing in certain locations might indicate specific alert levels or situations.
• Eye contact patterns: Floor staff learn to make brief eye contact in specific patterns to confirm they're aware of a developing situation.

The "Back Off" Process

When casinos decide to bar a player (usually for advantage play rather than cheating), a specific communication chain unfolds:

1. Surveillance identifies the player and communicates to the floor.
2. A pit boss receives the notification, often through earpiece.
3. The pit boss approaches the player calmly, often with a security officer positioned nearby but not obviously involved.
4. Using carefully scripted language, the pit boss informs the player their play is no longer welcome.
5. If the player cooperates, they're escorted out discreetly. If not, security becomes visibly involved.

This choreography is designed to handle the situation professionally while minimizing disruption to other guests—and ensuring the entire process is captured on surveillance cameras for legal protection.

Chip Color and Denomination Language

Casino chips have their own universal language, with colors representing specific denominations that staff use in verbal shorthand:

• White or blue: $1
• "Nickels" (red): $5
• "Quarters" (green): $25
• "Blacks": $100
• "Purples" or "Barneys": $500
• "Flags" (orange/yellow): $1,000
• "Chocolates" or "Melons": $5,000
• "Cranes" or "Grays": $25,000

These terms allow quick communication about bet sizes and payouts. "He's betting blacks" instantly conveys a $100 average bet to anyone in the industry. The security measures surrounding high-denomination chips are discussed in our article on casino chip counterfeiting.

Table Games Procedures: The Ritual Language

Beyond hand signals, table games follow strict procedural routines that function as a form of communication with surveillance and regulators:

The Card Shuffle Dance

Dealers follow specific shuffle routines that must be executed consistently:

• Wash: Spreading cards face-down and mixing them in circular motions, usually for a mandated minimum time.
• Riffle and strip: The specific number of riffles and strips varies by casino policy, documented and verified by surveillance.
• Cut card placement: Players cut the deck with a colored card, and its placement determines how deep into the shoe games will be dealt—a countermeasure against the card counting techniques that made the MIT Blackjack Team famous.

The evolution of shuffling procedures, including the introduction of automatic shuffling machines, represents casinos' ongoing efforts to maintain game integrity.

The Fill and Credit Process

When a table needs more chips (a "fill") or has excess chips to remove (a "credit"), an elaborate verification process occurs:

1. The dealer requests the fill through a pit boss.
2. A casino cashier prepares the chips with documentation.
3. A security escort brings the chips to the table.
4. Both dealer and pit boss sign paperwork confirming the count.
5. Chips are added to the tray in a specific arrangement visible to cameras.

Every step generates paper trail and video record. The purpose isn't paranoia—it's protection. Multiple employees must collude to steal during this process, and the documentation makes anomalies easier to detect.

Learning the Language: Training New Employees

Casino dealers undergo extensive training in this communication system before ever touching a live table. Dealer schools, both independent and casino-operated, spend weeks drilling procedures until they become automatic.

The Bureau of Labor Statistics reports that gaming dealers typically complete 6-12 weeks of training, with much of that time devoted to procedural accuracy. They must demonstrate perfect execution of signals, calls, and chip handling before being certified to deal live games. Even then, new dealers work under close supervision while their procedural habits are evaluated.

"The signals become second nature," explained one dealer with fifteen years of experience. "I don't think about clapping out anymore—my hands just do it. Same with the chip pushing, the card procedures, everything. But in training? They make you do each motion hundreds of times until it's muscle memory."

Regional and International Variations

While many casino signals are standardized, regional variations exist. European casinos may use slightly different roulette terminology. Asian gaming markets, particularly Macau, have developed their own vocabulary influenced by Cantonese and Mandarin—a topic tangentially covered in our article on Macau junket operators.

Some differences in international casino communication include:

• UK casinos often use traditional terminology like "croupier" and "punter" (for player) that has faded from American usage.
• Macau casinos incorporate Cantonese lucky number terminology and superstition-acknowledging phrases.
• Australian casinos use some unique slang, calling a good tipper a "punter's friend" rather than a "George."

However, the core hand signals for player decisions remain relatively standardized globally—a necessity as the gaming industry has become increasingly international.
