8 Casino Scams That Actually Worked

The average person you'll find in a casino is playing honestly. But some ambitious gamblers come up with schemes to beat the house for millions. Although most cheaters get caught, there are others who manage to hustle casinos successfully ... until they eventually get caught too. Here are eight casino scams that actually worked.   

1. Special Contact Lenses

Four con artists ripped off 64,000 euros (about $88,000) from poker tables at Les Princes Casino in Cannes, France in 2011. One of the cheaters (an employee of the casino) used invisible ink to mark the backs of playing cards—drawing a line for an ace and a cross for a king, for example—while the others used special contact lenses to spot the cards that would give them winning hands. Les Princes Casino grew suspicious of the players when they returned later in the week for a second round of high stakes poker. French authorities found the marked cards and noticed the cheaters' contact lenses after they ruled out cameras and infrared glasses.     

2. Cigarette Pack Radio Transmitters

In 1973, a French roulette dealer at the Casino Deauville, along with his sister and brother-in-law, took the casino for 5 million francs (about $1 million). The dealer built a radio transmitter inside of a pack of cigarettes and a roulette ball with a small receiver inside. When a button was pushed on the pack of cigarettes, the ball could be controlled to land on a specific part of the roulette wheel. The cheating trio had a 90 percent accuracy rate with the scam.

The only reason why they were eventually caught was the casino owner was infatuated with the roulette dealer's sister, who was in charge of pushing the button on the pack of cigarettes. The owner wondered why she always sat at the same roulette table and made very low bets without winning. Along with his growing suspicion and heavy losses at the roulette table, he called in a debugging crew to sweep the casino. The authorities found the radio transmitter and tiny receiver, as they also caught the trio in the act of cheating.

A French film titled Tricheurs (The Cheaters) was made about the trio and its clever scheme in 1984.

3. Edge Sorting

Professional poker player Phil Ivey, Jr. was accused of cheating the Crockfords Casino in London out of £7.3 million (about $11 million) during a high stakes game of Punto Banco in 2012. The casino believed that Ivey used a method of cheating called "edge sorting," which is the practice of keeping track of the tiny and minor imperfections on the back of face-down playing cards.

Edge sorting works because some cards aren’t cut symmetrically. For example, a card with a diamond pattern on the back might have a half diamond on the top right and a quarter diamond on the bottom left. Ivey and his associate had the dealer go through multiple decks until they found one that was asymmetric. Then Ivey had the dealer rotate some of the “lucky” cards to make the sevens, eights, and nines more noticeable (going back to the earlier example, those cards might now have the quarter diamond on the top right). Once they found their lucky deck, Ivey had the table increased from a $50,000 to a $150,000 maximum. While Ivey claims that "there's a difference between increasing one's odds and cheating," British courts ruled that edge sorting constitutes cheating and sided with Crockfords.

In 2014, Ivey won $9.6 million at a baccarat table at Borgata Hotel Casino and Spa in Atlantic City, but the casino refused to pay him; the house believed that he used edge sorting to win.

4. Sector Targeting with Lasers

In 2004, three gamblers used a unique system of lasers and computers called "sector targeting," which calculates the falling descent of an object in motion, to correctly predict the part of the roulette wheel where a ball might land, hustling £1.3 million (about $2.1 million) at London's Ritz Casino. Based on the speed of the roulette ball, it's believed the players would secretly scan the wheel with lasers in their cell phones, which were connected to small computers, to determine where the ball might land. Although the system predicted the area it might land on, it doesn't predict the number or color the ball might fall on. The players would then make bets accordingly.

While the trio managed to take millions from the casino, they were arrested but ultimately not charged with any wrongdoing because there were no laws prohibiting the use of sector targeting at the time. Of course, it is possible that they were just using their phones as stopwatches.

5. Counting Cards

In 2011, Phuong Quoc Truong assembled a team of 30 card counters and blackjack dealers to rip off various casinos in Southern California. Dealers would pretend to shuffle a deck of cards, but they'd just put the corners together to make the sound and appearance of shuffling while actually keeping the cards in the right order for dealing winning hands. A signaler pretended to smoke a cigarette, but was really using a small microphone on the inside of his sleeve to tell an outside person what was on the table. Once the right cards were in place, the outside person would tell the smoker how to place bets, while the smoker signaled the players with his cigarette.

Sickwan Gaming Commission finally caught the gang, but not until after they took nearly $7 million from 25 different casinos. Truong and most of his accomplices pled guilty and are serving sentences that range from probation to six years in prison. Truong also forfeited his two luxury homes in San Diego, a Porsche, a diamond-encrusted pendant, and a Rolex watch for his part in the crimes.

6. The ATM Job

In 2012, ringleader Ara Keshishyan recruited 13 people to pull an Ocean's 11-esque bank heist on Citibank ATMs throughout casinos in Southern California and Nevada. The scam involved exploiting the security protocol on Citibank’s cash advance kiosks, which allowed multiple withdrawals at 10 times the amount deposited—if the transaction was made within 60 seconds. The scam would then result in hefty cash payouts from casinos. Keshishyan also instructed his gang to keep withdrawals under $10,000, so their illegal activities would not be reported to the government. The team would use the stolen money to gamble and thus have casinos give them complimentary rooms, food, drink, and entertainment based on their "high roller" gambling level.

Ultimately, Citibank noticed the discrepancies and alerted the FBI. The scammers were caught and faced up to five years in federal prison and a $250,000 fine. Keshishyan was ultimately sentenced to 57 months in prison and ordered to repay Citi the $1,045,585 he stole from them.

7. Counterfeit Coins

Louis "The Coin" Colavecchio successfully made counterfeit coins and tokens to use at slot machines at various casinos across the country. He used his ties with organized crime as well as his day job as a jeweler to make perfect dies. Casinos figured out they were being scammed when they discovered a surplus of tokens and slot machine coins in their vaults.

Colavecchio was arrested in 1998 and sentenced to six years in prison. In 2006, he was arrested when he started to reproduce fake casino tokens again. The History Channel made a documentary about Colavecchio called Breaking Vegas; many casinos now use special paper vouchers instead of tokens when players want to cash out of slot machines.

8. Roulette Scam

Ohio Casino Control Commission believed that 50 to 70 people were involved in an elaborate casino scam at roulette tables throughout the Buckeye State in 2012. The hustle involved players entering busy roulette games with bets as low as $1 and swiping casino chips while their accomplices distracted roulette dealers. The players would then go to areas in the casino that were not under surveillance like public restrooms to pass along stolen chips to other players, who would return to use them to buy more chips at a higher rate and cash out.

Scammers were caught in casinos throughout Ohio pulling the same gambit, with groups taking as much as $1000 to $2000 per job. Authorities believed that the group was based in New York City and hit multiple casinos in 18 different states. Many of the roulette scammers are still at large, while a small handful were caught and face strict penalties in Ohio, such as a $2500 fine and one year in prison.

25 Offbeat Holidays You Can Celebrate in December

Whether you're a holiday fanatic who wants even more to celebrate, or a Scrooge with a burning desire to buck tradition, we've got plenty of offbeat observances to put on your calendar.

1. December 1: Giving Tuesday

After indulging on Thanksgiving, and shopping on Friday, Monday, and probably the whole weekend in between, Giving Tuesday—which occurs annually on the Tuesday following Thanksgiving—encourages people to engage in charitable activities.

2. December 4: National Cookie Day

December isn’t exactly lacking in opportunities to indulge in sweet treats, but today it’s your offbeat-holiday-given right to mix, bake, and/or eat as many cookies as you can handle.

3. December 5: Bathtub Party Day

There's a lot to be done between now and the end of the year. Take a minute to breathe, relax, and take in a soak.

4. December 5: International Ninja Day

The official website of Ninja Day alleges this holiday not only honors all things stealth and nunchucks, but also combats the more nautical offbeat holiday Talk Like a Pirate Day, which takes place in September. Creep, sneak, or redirect all of your URLs to Ninja activity—as long as you forgo the “arrrr matey’s” and eye patches for ominous silence and masks, you’re correctly celebrating this international holiday.

5. December 6: National Pawnbrokers Day

If you thought good ol' St. Nicholas was the patron saint of reindeer and stockings, think again: The actual Nikolaos of Myra was the patron of things like the falsely accused and pawnbrokers, and on this day we acknowledge the latter.

6. December 9: Weary Willie Day

Professional clown Emmett Kelly created one of the more memorable clown characters of the 20th century: “Weary Willie.” Unlike many of his clown predecessors, Weary Willie opted out of white face paint and broad slapstick for the “tramp” look popular among Depression-era derelicts. One of his signature routines involved attempting to sweep up after circus acts, and failing in spite of himself—to the delight and empathy of the audience.

7. December 10: Jane Addams Day

December 10 is the day that the Nobel Prize Award Ceremonies have been held every year since 1901. Consequently, there are a lot of firsts that fall on this date, like the first American woman to be honored. That would be Jane Addams, founder of our current social work industry and prominent women's suffrage leader. On the anniversary of that award, given in 1931, we remember her life and work.

8. December 11: Official Lost And Found Day

Visit a thrift store, see if you can find that book you’ve misplaced, or invest in a memory-boosting regime so you’ll be losing things less frequently.

9. December 12: Poinsettia Day

This day doesn't just celebrate the festive flower—it also marks the death of its namesake, Joel Roberts Poinsett. The botanist (and first U.S. Ambassador to Mexico) brought clippings of Euphorbia pulcherrima back to the States from southern Mexico, and grew the plant at his South Carolina home.

10. December 12: Gingerbread Decorating Day

Whether you’re a craftsman or an eater, today is the day for you.

11. December 13: National Day Of The Horse

In 2004, the Senate signed legislation to officially make the second Saturday of December the National Day of the Horse. We really shouldn’t have to explain the reason horses need to be celebrated—just look at them!

12. December 13: National Cocoa Day

The weather outside is starting to get frightful, but what better cure for the temperature blues than a nice cup of hot cocoa? A down coat or a wool hat simply can’t compete in the taste department.

13. December 14: Monkey Day

Officially, Monkey Day is an “annual celebration of all things simian, a festival of primates, a chance to scream like a monkey and throw feces at whomever you choose.” The origins of the holiday are unknown, though it has been observed since at least 2003.

14. December 15: Cat Herders Day

Technically this day is for all those who work jobs that could be described as like trying to herd cats, but it’s also probably acceptable to celebrate by trying to wrangle a cute feline.

15. December 16: Barbie And Barney Backlash Day

nicescene/iStock via Getty Images

Doesn’t seem like a coincidence that this holiday occurs in December: It’s the one day a year when you can tell your kids that Barbie and Barney don’t exist.

16. December 17: Wright Brothers Day

Made an official holiday in 1963 by Presidential Proclamation, this holiday marks the day in 1903 when Orville and Wilbur Wright achieved the first ever successful (documented) controlled airplane flight near Kitty Hawk, North Carolina.

17. December 18: Underdog Day

Observed annually on the third Friday of December since 1976, this is a reminder to honor the little guy. We’re always rooting for them, but there’s a holiday to celebrate, too.

18. December 21: Humbug Day

Michael Burrell/iStock via Getty Images

Get out all your bahs and scowls and growls now: no one will tolerate them come Christmas.

19. December 21: Phileas Fogg Win A Wager Day

In Jules Verne's 1873 classic novel Around the World in 80 Days, Phileas Fogg bets that he can travel the entire globe, between 8:45 p.m. on October 2, and 8:45 p.m. on December 21. Keep an eye out for him on this day.

20. December 22: Forefathers’ Day

On December 21, 1620 (it was a Monday) the Pilgrims aboard the Mayflower landed in Plymouth, Massachusetts, and since that basically kick-started our country's history since then, we celebrate it.

21. December 23: Festivus!

SafakOguz/iStock via Getty Images

For those who shy away from the more traditional December holidays, there’s always Festivus for the rest of us. Created by a Seinfeld writer's father and popularized by Frank Costanza, this secular holiday that involves gathering around an aluminum pole and airing your grievances has continued to gain a following since its introduction in 1997. If you haven’t seen the episode, there’s an entire website that spells out how to celebrate Festivus from start to finish. (Test your Festivus knowledge with this quiz.)

22. December 25: A’phabet Day

A pun on noel, this offbeat ce'ebration is designed to high'ight the arbitrary nature of many of the year's si''ier ho'idays.

23. December 26: National Whiners Day

In case you needed another reminder of the inevitable passage of time and/or an occasion to reevaluate how those 2019 resolutions are going!

25. December 31: Make Up Your Mind Day

Tomorrow’s a new year! Time to fight that indecisiveness and make a decision—maybe even a resolution, if you will.
