Famous Gambling Grifters

If you’ve ever snuck a peek at my bio, you may know that I have a history degree. I love an opportunity to marry two of my passions; history and gambling!

At times, we’ve looked into some of the history of gambling, including a fantastic overview of the history of our beloved bingo.

We’re always telling our players that gambling is just a bit of fun and is not a way to seek a fortune. Some players get very lucky and win a jackpot but most do not! As we always say, it’s just another form of entertainment, like going to the cinema.

However, these five historical figures did not heed our warning and tried to cheat their way into making their fortune. Crime never pays; the house, and the law, always wins!

We run down five of history’s most notorious gambling grifters and criminals who attempted to lie, cheat and steal to make their fortunes. Each, in their own way, contributed to high tech, high security games that we’re used to today!

Tommy Carmichael

Tommy Glenn Carmichael took the casino world by storm in the 1980s, giving a famous quote;

“Give me a slot machine and I’ll beat it.”

He was a wiz with mechanics and spent his life developing a series of devices to try to cheat the old-fashioned slot machines.

Way back when Vegas were still using mechanical slots, Carmichael invented a wire-rigged trap called the top-bottom joint. This tiny chip could induce an instant pay-out when put into the coin slot. However, he was caught red-handed relatively quickly and thrown in prison. A lot of people speculate that Carmichael used the majority of his sentence coming up with even more tricks and cheats!

When finally free from jail time, Carmichael went straight back to his favourite cheat testing ground, only to discover slot machines now featured random number generators (RNGs). It was time for a bit of undercover reconnaissance.

Carmichael disguised himself as a casino employee, convincing a manufacturer to show him the inner workings of new slot machines. He then came up with the “light wand,” a simple electronic contraption that could trip the internal sensor on a machine, causing it to pay out coins.

It seems the man never learned his lesson. He was caught and arrested again in 1996, then several more times over the next few years.

You can thank Carmichael for the rapid development of slot security as he forced casinos to come out with increasingly advanced technology, resulting in the high tech slots we have today!

Louis Colavecchio

Louis Colavecchio, nicknamed The Coin, ran one of the most incredible coin counterfeiting operations of the 20th Century. However, Colavecchio wasn’t imitating actual money, but casino tokens!

Tokens are unique to the casino they come from, so Colavecchio was forced to steal a single coin each from several casinos in North America. By using them as a template alongside highly complex materials and technology, Colavecchio didn’t just create imitations, but somehow managed to produce exact replicas, previously believed to be impossible!

Experts estimate Colavecchio managed to steal around $500,000 before the feds finally caught on to him – raiding his Colorado home to discover laser-cutting tools and a 150-pound press imported from Italy.

Ida Summers

Ida Summers was the femme fatale of gambling throughout the 60s and 70s, back when it was still very much a man’s world. She was known to be extremely beautiful and sociable, using her charms to distract from the sleight of hand tricks she favoured. Plus, her slim frame and 5’3 height made her appearance as small, unintimidating and innocent as possible.

Many Vegas casinos had mob connections in the 1960s, so cheating could be downright suicidal. Summers was a cool calm criminal. Using techniques like ‘hand mucking’ and switching in ‘coolers’ at the Blackjack tables, it is estimated she robbed the Vegas scene of well over tens of thousands of dollars, evading capture for one of the longest stretches of time in gambling history.

Summers continued to grow increasingly cocky, bringing ‘cold decks’ (pre-stacked decks) into play. This is an incredibly dangerous manoeuvre, but somehow she pulled it off, and right in the middle of a crowded casino too. Summers became a legend; no one in their right mind had ever attempted to insert a cold deck before.

Eventually, rumours spread and the FBI got involved, teaming up with gaming officials to bring the vixen down. However, even in court Summers managed to charm the crowd with a bit of ‘razzle dazzle;’ she only got probation – no jail time or fines were issued.

Ron Harris

Ron Harris is one of the most notorious cheats in Vegas’ gambling history, blacklisted from all casinos across the world and even inducted into the online cheaters’ Hall of Fame.

He was a computer programmer for one of the biggest casino gaming providers in Nevada. He worked in the early 1990s finding flaws and bugs in software that ran computerized casino games. He soon found a much more illegal use for these talents.

Taking advantage of his expertise, reputation and access to source code, Harris was able to modify certain slot machines, tricking them into paying out enormous real money jackpots when a specific sequence and number of coins was inserted.

It is estimated that Harris and his accomplice, Reid McNeal, stole thousands of dollars from all the top Vegas casinos at the height of his scamming streak between 1993 and 1995. This soon became one of the most successful undetected fraud scams officials had ever encountered. However, partners in crime cannot always be trusted, and it was the accomplice McNeal who proved to be the end of this operation. Casino bosses became suspicious at Bally’s Atlantic City Casino Hotel when McNeal attempted to redeem a high value winning keno ticket. He showed a lack of excitement and surprise that immediately put witness suspicions on edge. An investigation was launched.

It didn’t take long for the authorities to find a link to Harris’ involvement, especially considering his occupation as a casino computer programmer. After a trial, Harris was sentenced to seven years in prison. He was released after serving 2 years, and apparently still resides in Las Vegas, which is rather ironic in our opinion!

Harris became so notorious that his story can be seen on the Bio Channel, History Channel and Discovery Channel program Breaking Vegas, which features interviews and re-enactments of some of Harris’ memorable moments in his casino-breaking scheme. In the opinion of some casino experts, Harris is one of the most “infamous cheats” of modern times.

Archie Karas

Archie Karas broke records with the largest and longest documented winning streak in gambling history from 1992 to 1995. The poker player came to Las Vegas with $50 in his pocket and left after three years with a $40 million high-stakes fortune.

Unfortunately, he later lost the majority on baccarat and dice games within just three weeks! Karas returned to poker several more times since, usually backed by rich investors. He ended up crushing many of the world’s best players.

However, Karas was caught marking cards at a California blackjack table. He was pulled from his Las Vegas home into police custody, charged with burglary, winning by fraudulent means and cheating. This wasn’t the first time Karas was caught cheating either.

Enforcement chief, Karl Bennison, said in a statement that:

“The Nevada Gaming Control Board has investigated Karas on multiple occasions resulting in four arrests… Karas has been a threat to the gaming industry in many jurisdictions.”
