Poker Cheaters Allegedly Use Tiny Hidden Cameras to Spot Dealt Cards

Matt Berkey was becoming suspicious.

Berkey, a 42-year-old poker pro known for his presence in some of the highest-stakes cash games in Las Vegas, was playing in a well-known casino poker room over the summer. One player in the game who wasn’t particularly familiar to Berkey and other regulars at the table, but who was believed to be an amateur based on his play style, was displaying some strange behavior.

For one, the player was wearing earbuds—typically a no-no in these kinds of semi-private games where many players have existing friendships.

“Nobody has headphones on during our games,” Berkey says. “The player in question had headphones in, so that’s already a bit off.”

The player’s style of play also raised some alarms.

Texas Hold’em, the game being played, features two individual cards dealt to each player, plus five community cards dealt in stages to the center of the table. Players combine their own cards with the community cards to make the best possible five-card poker hand. There are four rounds of betting: One before any communal cards are dealt, one after the first three communal cards are spread at once (the part of the game known as “the flop”), one after the fourth communal card (“the turn”), and one more after the fifth and final communal card (“the river”).

Berkey noticed that, despite presenting as an amateur who was clearly the least skilled player at the table, the suspicious player never seemed to lose on the river. When he was in a hand that reached that point, he always either folded or showed the winning hand—one of the first red flags seasoned poker players have come to recognize in suspected cheating situations. As the thinking goes, cheaters with knowledge of their opponents’ cards prefer to wait until all communal cards are dealt before making large bets, allowing them to do so with perfect information about who holds the best hand, which often isn’t certain until that final card.

“Playing all rivers perfectly over an eight-hour sample—that’s an anomaly that isn’t really statistically possible, especially from a recreational player,” Berkey says. “When you start to see things that don’t add up, like the least skilled player in the game never showing down a losing hand, that kind of begins to trigger your suspicions.”

The player also had his phone and earbuds case arranged around him, with the case on the felt and his phone on the rail that runs along the table’s edge. While occasional phone usage at poker tables is normal, that kind of arrangement is unusual and is even something many casinos have guarded against for years. Berkey began to wonder if this game was falling victim to a new cheating scheme that word had been spreading about in high-stakes circles for months: Hidden cameras placed at felt level, capturing the faces of cards as they’re dealt and transmitting that intel to an accomplice, who then relays it back to the player at the table through an earpiece.

Berkey also noticed that the player always seemed to sit in the seats directly to the left of the casino’s dealer, even across multiple days and playing sessions. That furthered suspicions, as the rumored cheating method required a player to be in these seats to maximize camera visibility.

Berkey says he quietly alerted other regulars of his suspicions, and the game eventually broke down, but not before the player had made enormous profits. “Not just for his skill level but for the stakes he was playing,” Berkey says. “He was up hundreds of thousands of dollars playing a $10,000 buy-in game.”

Berkey says he and the other regulars in the game flagged the incident to casino staff, but they are unsure what, if any, action was taken. Security for the casino declined to comment on this incident.

Several other such incidents involving the same suspected cheating method have been rumored in various locations over the past 18 months, including one other instance WIRED verified independently. (Specific casinos where these incidents are alleged are not being named in this story to protect the safety of players who confirmed the incidents occurred.) This form of cheating is now a known concern to high-stakes poker players everywhere.

But each of these rumored incidents has lacked a “smoking gun”—proof of the measures, methods, and equipment the cheaters were using to see the cards being dealt. That is, until recently. A breaking case in France has provided revealing new evidence, fueling concerns that this cheating method is rampant around the globe and may be more advanced than anyone had assumed.

What kinds of modern technology can facilitate such a scheme? Should poker players at all levels, not just high-stakes pros, be worried about scofflaws attempting it in games they play, and what can be done to prevent it?

The recent scandal sounds like a rejected Ocean’s movie script.

Following tips of suspicious behavior at a major casino in Enghien-les-Bains, French police with the Central Racing and Gaming Service (SCCJ) launched an elaborate in-person and video surveillance operation around two suspected players at both blackjack and Ultimate Texas Hold’em poker (a type of poker played against the casino rather than against fellow players). Though they were initially in the dark about the method being used, investigators soon noticed a pattern.

“They were putting [something] beside the [dealing] shoe,” Stéphane Piallat, commissioner of SCCJ, alleges to WIRED, referring to the tabletop container a dealer pulls from to draw new cards. “But it was quite difficult to understand why.”

Both players were arrested inside the French casino in late July after weeks of surveillance, with police recovering a variety of items from both their person and their hotel rooms (including ID cards from casinos around Europe that suggested a prolonged scheme). The technology seized by law enforcement amazed even a seasoned gambling fraud officer like Piallat, both for its ingenuity and its relative simplicity.

The players had allegedly modified existing smartphone cameras with simple mirrors, allowing them to capture footage on a phone’s camera sensor laterally, while the phone was in a flat position. Sitting in the seat nearest to the dealer’s shoe, they placed these devices either on the felt (concealed in some situations by a hat or another piece of clothing) or within pockets of their own clothing (with tiny holes cut out to afford the camera a view of the cards). Police say they used these devices to capture card faces as they were dealt from the shoe—a stunning realization given that casino shoes are quite literally designed to prevent card exposure by allowing the dealer to slide new cards directly onto the felt. Clearly, some exposure was still being captured.

“It’s quite incredible,” Piallat says. “They didn’t need to mark cards … Those cards were normal cards.”

Police also recovered basic communication devices that transmitted these feeds to an outside accomplice, believed to be sitting in the casino parking lot. (As of WIRED’s interview with French police, this accomplice remains at large.) The accomplice is thought to have relayed information about which cards the dealer was holding back to their partner at the table, but not through a standard earbud.

“This device is so small that you can’t take it off with your fingers,” Piallat says of the hearing device recovered by police. “You need a magnet to pull it off, otherwise you can’t do it. It looks like a typical James Bond movie device.”

Due to the ongoing nature of the investigation, police declined to provide any pictures or further details about the specific items used to facilitate this scheme. A simple look at available technology, though, offers a number of cheap, simple candidates, including several that don’t require pairing with a phone or any other large device.

“The same kind of modules that are used in your iPhone or your DSLR, you can just buy them,” says John Coles, the director of technology for the VR company Rezzil, who has also spent years working in camera and broadcast technology.

The alleged cheaters in France used simple techniques to conceal their cameras, like hiding the devices in their clothing, but much more robust options exist on the open market. A device that looks like a battery charger may not cause alarm if it was spotted sitting on a poker or blackjack table, at least in casinos where devices are generally allowed (some have stopped allowing any devices on tables); one can find a 4K, Wi-Fi capable “hidden camera powerbank” on Amazon. (It’s marketed as a “nanny camera” for surveilling your child’s babysitter, naturally.) Even smaller options exist, like a “spy camera pen” or a pinhole camera that could easily be inserted into various items. And that’s just a fraction of the true marketplace, says Coles: “If that’s what you know about publicly, the stuff that exists behind closed doors is like 10 times what you’re aware of.”

“You could probably build that into a lighter,” Coles says of a typical tiny camera rig. “There are lighters and pens that have modules integrated that still work as those items so they’re less conspicuous.”

For bad actors at traditional poker tables that feature “pitch”-style dealing instead of a more secure casino shoe, the video quality demands are even lower. Card faces are visible for exponentially longer when pitched from a dealer’s hand situated a foot or so above the card table.

The transmission element of the scheme is similarly attainable using today’s technology. You can buy a “mini spy earpiece” from Amazon that receives signals from an inductive coil for just $18. An entire industry of earpieces appears to exist for exam cheating purposes, from tiny Bluetooth earpieces that connect to a phone to setups contained within glasses and pens. It’s easy to imagine these methods converted for use in cheating at the card table, especially when aided by basic video-calling technology and access to the Wi-Fi networks offered at most casinos. In fact, while police say the suspects in France allegedly used separate devices for capture and transmission, Coles believes it would be simple enough to handle the entire operation with a single device.

“I think it’s kind of surprising that a lot of these things don’t happen sooner, to be perfectly honest,” Coles says, noting that many of these cameras, earpieces, and transmitters have existed for a decade or more.

“You could do it with a very cheap investment,” Piallat says. “You won’t need a lot of money.”

Clearly, these schemes are out there and available. So should poker players everywhere be concerned?

Mini-camera cheating is now an open secret in the poker community, from its references in forums to an entire August episode from Berkey’s Only Friends podcast that covered the alleged methods in detail. And if casinos and law enforcement weren’t aware of it much earlier, they certainly are now; Piallat confirmed to WIRED that his unit dispersed information about the case around the globe through Interpol networks.

What can casinos, players, and law enforcement do about it, though?

The first step is simple vigilance, something all these parties are well-versed in. Policing of suspicious players happens at casino level. WIRED independently confirmed a separate alleged incident at a different casino in June that included an individual reportedly earning seven-figure profits before disappearing. The alleged cheater in this case hasn’t been seen since, and Berkey wonders if he was banned from this and possibly other casinos.

“It would seem as though the Vegas casinos have acted,” Berkey says.

Those are retroactive measures, though; what about stopping this cheating as or before it happens?

Some Vegas casinos, per multiple sources, have begun banning phones from being set down at felt level on tables. Many casinos have long had policies prohibiting phone use during hands, and some have even banned phones entirely in prior years, and now these efforts are growing more widespread. However, with the knowledge that today’s miniature cameras can be built into lighters, pens, and other non-phone devices, is that enough of a safety measure? A true “no items on the table whatsoever” rule feels more prudent, but will casinos view that as too invasive toward their clientele? Then there’s a whole separate conversation about placing devices on the rail, which is where players rest their elbows and which sits slightly higher than the felt itself.

“There will be guys who want to watch the game at the table and have their phone propped up,” Berkey says. “That should just be fine. It’s a fine line; it’s a gray line.”

Berkey even suggested some sort of hybrid arrangement where phones or other devices are allowed so long as they sit behind chips or some other item that blocks their view of the felt. These solutions, though, also fail to account for rings or other jewelry that may contain a concealed camera.

The device removal tactic would have run into another big snag when the arrests in France took place: One of the suspects had nothing on the table at all. He allegedly concealed a camera in his clothing. If that scheme worked to capture card faces out of a dealer’s shoe, it would definitely work for the traditional dealer-pitch style used in Vegas.

The better long-term solution, one Berkey and others in the poker world support, involves retraining the dealers—a process that’s already begun.

The European Poker Tour has introduced a new form of dealer pitch known as slide dealing, where the deck remains on the table and the dealer slides each top card off individually to greatly minimize or eliminate any exposure. EPT tournament director Toby Stone directly cited issues of camera cheating as the impetus behind this change, which took effect within the past couple of months.

Casinos could take it even further; some have been cracking down for years. The Star casinos in Australia, for instance, have long used a modified version of a blackjack shoe meant for a single poker deck, which sits at the center of the table and allows cards to slide out from within it. This ostensibly makes it much harder to capture cards than from the traditional blackjack shoe placed at the very side of the table, closer to potential cameras. Anecdotally, these contraptions also seem to limit or eliminate other common risks like bottom-dealing or cards flipping over while being dealt.

While it might take time to retrain the world’s legion of poker dealers to mitigate these schemes, that could be the eventual outcome here.

“I’ve spoken to a few of the [casino] higher-ups, and it seems they’re all open to the idea of retraining dealers,” Berkey says.

Maybe even that eventual move wouldn’t completely eliminate mini camera cheating. As the suspects in France allegedly showed us, today’s video technology is truly amazing. Would you ever have guessed a mini camera could accurately capture which cards are being dealt during the split second they’re exposed as they’re pulled from a blackjack shoe?

Anyone putting their money down at a casino, particularly higher up the stakes spectrum, should at least be aware of the risk of bad actors—particularly in a game like poker, where your opponents are other patrons rather than the casino itself. Whether to combat this or any other potential scheme, a dose of diligence goes a long way.

“As long as there’s a fair game to be offered, there will be people who will try to corrupt it,” Berkey says. “The best we can do is continually work hard to keep the game as fair as possible.”
