Scammers use tricks to target gamblers. Some set up fake gambling sites and use rigged games to deceive players. Fraud has grown over eighty percent in recent years. Victims lose billions of dollars every year because of these scams. The online gambling industry could reach $1.4 trillion by 2030. This report lists types of scams and shows players which warning signs to check before they lose money.
The Scale of Casino Scams Worldwide
Cheating scams cost the industry millions of dollars every year. In 2023, the online gambling market reached over $70 billion. Fraud in online gambling takes about a billion dollars each year.
Consumers told the FTC they lost over $1.4 billion to online gambling and investment fraud in recent years. Statista says at least 977.3 million people will use online gambling by 2029. A 2024 study found that one in four scam victims had taken formal cybersecurity training.
How Do Rigged Online Casinos Trap Players?
Fraudsters set up websites and display licensing seals to appear legitimate. After gaining players’ trust, they program sites that block any chance of winning.
Operators target players who are unaware they are being manipulated through channels.
- Real-money games run with RTPs as low as 70%;
- RNG tampering ensures the house wins far more than advertised;
- Withdrawal freezes occur under false security concerns;
- Malware embedded in downloadable apps steals wallet credentials;
- Play Store lookalikes distribute fake applications tied to illegal gambling websites;
- Fabricated celebrity endorsements lure victims through deepfake videos.
What Makes Card Manipulation Hard to Detect?
Card manipulation involves altering cards by inking, bending corners, or scratching them to create marks, and sometimes collaborating with casino staff to introduce marked decks.
Detection remains difficult. New techniques continue to evolve, making them challenging to identify consistently.
- In 2011, three individuals used specialty contact lenses to read cards marked with invisible ink — Kings and Aces — by a bribed casino employee;
- Special ink visible only through specific glasses or contact lenses is now a documented card-marking method;
- Second dealing — dealing the second card from the top instead of the first — is a technique used by specialists known as card mechanics;
- Past posting, where players place bets after the ball or outcome lands, relies on distractions to the dealer or sleight of hand;
- Hand mucking — secretly switching cards during gameplay — is another form of deck tampering;
- In one baccarat scam, a portable shuffle machine was swapped with a replica fitted with a micro-camera, transmitting card sequences to a phone; casino losses reached $1M–$10M per incident.
Collusion Between Players and Staff
Dealer collusion is among the most difficult types of fraud to detect. Some cheating originates inside the casino rather than outside it, as employees can work with players to cheat casinos.
Tactics shift over time. Each one aims to take money from the house while avoiding detection.
- Dealer signaling – Staff members communicate hidden card values to accomplices at the table;
- Sleight of hand alterations – Dealers manipulate cards or dice during active play to favor specific players;
- Whipsaw moves – Two colluding players constantly raise each other to force others out of the hand;
- Team play positioning – Groups strategically sit at tables to exploit weak dealers or vulnerable games;
- Dice slide scams – One player slides a die to fix the result range while team members create distractions;
- Card theft during delivery – Staff intercept cards before they reach the gaming floor and mark them in advance.
Chip Counterfeiting Methods
Fraudsters make tokens that look real. They put these fakes into games or swap them for cash. When players move during games, real and fake casino tokens mix. Dealers have trouble telling them apart. Holographic images used to help. Now, people can buy holograms online and stick them onto chips.
In 2010, a man took $1.5 million in chips from the Bellagio casino in Las Vegas. Casinos use RFID tags in chips. Staff track chips and check if they are real during games. They also put UV ink on lower-value chips to protect them from counterfeiters. In 2014, a poker player tried to use $2.7 million in fake chips during a Borgata tournament in Atlantic City. Staff stopped the event, and police arrested the player.
Slot Machine Tampering Techniques
Fraudsters target slot machines more than other casino games. Some tamper with a machine’s hardware or software to get odds. When slot machines ran on parts, criminals used tools to break into them. When casinos switched to electronic slot machines, fraudsters changed their methods. Some used lanterns to confuse sensors.
Amateurs often get caught, while professional fraudsters in slot scams usually avoid punishment. Some people hack slot machines’ random number generators, allowing them to control results. Some users try smartphone apps or USB devices to find and exploit flaws in slot machines. One fraudster made detailed fake slot tokens. A judge sentenced the fraudster to more than six years. The government paid the fraudster $18,000 in consultant fees to explain his methods.
Multi-Accounting and Identity Theft
Fraudsters make accounts by setting up many profiles at once. Criminals use stolen credentials and fake papers to open hundreds of accounts. They use stolen or fake identities when they create these profiles.
Fraudsters use account fraud methods to target operators and players.
- Account takeover fraud – criminals steal login credentials and drain balances or abuse bonuses;
- Location spoofing – VPNs and GPS manipulation hide true locations to bypass restrictions;
- Bot farm operations – automated software controls dozens of accounts simultaneously in poker rooms;
- Affiliate fraud schemes – fake referrals generate commissions without real player activity;
- Card-not-present fraud – stolen payment card data funds accounts without physical verification;
- Credential stuffing attacks – automated tools test leaked passwords across multiple sites.
Money Laundering Through Casinos
Criminals use casinos to launder illicit money. They buy casino chips with illicit funds and blend in with other players. They gamble just enough to avoid attention, reducing the risk of detection. Later, they exchange the chips for cash, making the money appear to come from legitimate gambling winnings. Cryptocurrency has worsened the issue because blockchain transactions can conceal the money’s origin.
Players sometimes engage in chip dumping, intentionally losing at poker tables so their partners can cash out the winnings. Others structure transactions by breaking up large sums into smaller amounts to avoid reporting requirements and detection by anti-money laundering systems. Layering and integration use moves, smurfs, casino credit accounts, and cross-border transfers. Some individuals move money abroad by depositing funds in junket accounts in one country and withdrawing an equivalent amount elsewhere. iGaming platforms present opportunities for money laundering, with people relying on bonus abuse and e-wallet tactics to conceal the origins of funds. In October 2024, European authorities dismantled a major betting ring that used false IDs, VPNs, and forged documents.
AI and Deepfake Casino Scams
Scammers use AI chatbots to pose as customer support representatives. They can set up fake review sites. Some scammers create deepfake videos with celebrities. Technology introduces new scam types in the gambling sector, such as AI fraud and deepfakes.
A person can clone a voice in three seconds. By 2023, people found 500,000 deepfakes online. That number grew to 8 million in 2025. Deepfakes make up 40 percent of all biometric fraud attempts. People saw deepfake fraud attempts rise by 2,137 percent in the past three years. In 2025, AI impersonation scams increased by 1,400 percent from the year before. For online gambling fraud, 41.9 percent happens during deposits.
Why Are Payment Frauds Increasing?
Gambling sites handle deposits and withdrawals every day. This flow of transactions makes their payment systems open to attacks. Carding is one example. Fraudsters take stolen card details and use them to load money onto accounts. They turn funds into winnings this way. When someone uses a stolen card, the cardholder may notice and ask their bank for a chargeback. In these cases, gambling sites lose the money and must pay processing fees.
Payment fraud takes several forms, including stolen credit cards, fake accounts, fraudulent casino sites, and identity theft. The rise of deepfakes and synthetic identities has contributed to a recent surge in these activities. According to Sumsub’s Identity Fraud Report, iGaming fraud has increased in recent years. Attackers also exploit phone top-up abuse. They use phishing and social engineering to convince people to send money through mobile payment systems linked to gambling accounts. Victims of card-not-present fraud often cannot recover their money once the transaction is complete. KYC verification requires individuals to upload personal information, such as scans of government-issued IDs and financial documents. When fraud slips through, it can create weaknesses in AML programs. As a result, compliance teams may face legal consequences and fines.
