Rigged Poker Games

The Department of Justice has indicted thirty-one people over the high-tech rigging of high-stakes poker games.

In a typical legitimate poker game, a dealer uses a shuffling machine to shuffle the cards randomly before dealing them to all the players in a particular order. As set forth in the indictment, the rigged games used altered shuffling machines that contained hidden technology allowing the machines to read all the cards in the deck. Because the cards were always dealt in a particular order to the players at the table, the machines could determine which player would have the winning hand. This information was transmitted to an off-site member of the conspiracy, who then transmitted that information via cellphone back to a member of the conspiracy who was playing at the table, referred to as the “Quarterback” or “Driver.” The Quarterback then secretly signaled this information (usually by prearranged signals like touching certain chips or other items on the table) to other co-conspirators playing at the table, who were also participants in the scheme. Collectively, the Quarterback and other players in on the scheme (i.e., the cheating team) used this information to win poker games against unwitting victims, who sometimes lost tens or hundreds of thousands of dollars at a time. The defendants used other cheating technology as well, such as a chip tray analyzer (essentially, a poker chip tray that also secretly read all cards using hidden cameras), an x-ray table that could read cards face down on the table, and special contact lenses or eyeglasses that could read pre-marked cards.

The odds of making a mint playing poker surely can’t be great. But illegal poker?

What’s that poker proverb? If you look around the poker table, and you don’t know who the patsy is …

From the recent indictment:

… Victims of the Rigger Poker Scheme (the “Victims”) believed they were participating in “straight” illegal poker games and that they were gambling against other participants on equal footing.

To be fair, the technology involved is relatively advanced. WIRED’s Hacklab has an awesome video about the inner workings of the Deckmate 2, and associated ‘technologies’.

It’s reported that just in these Rigged Games, the ROI was over $7 million. Plus an indictment, I guess.

Those scammers had already earned millions through their “football” careers. But apparently that was not sufficient.

@George: Just for the record, I believe the alleged scammers are basketball players, not football players.

NEW YORK (AP) — The head coach of the Portland Trail Blazers and a player for the Miami Heat were arrested Thursday along with more than 30 other people in two criminal cases alleging sprawling separate schemes to rake in millions by rigging sports bets and poker games involving Mafia families, authorities said.

The Trail Blazers and the Heat are both NBA teams.

@ Bruce, ALL,

This is in reality a “technology update” that is,

“Old sour wine in new bottles.”

Most of these tricks have been done before.

And the use of X-Rays certainly not required to “see through a table”, much lower non Visible EM frequencies will do the same if the cards and table top are selected with care.

Think about how what looks like a smoked glass table top can be “under lit” with Infra Red, and if the ink used on the cards is designed to be highly reflective to that IR frequency, a suitable camera under the table would be sufficient…

Another old variant is a “shiner” think about a highly polished metal cigarette case it works almost like a mirror. And has been used by the person “dealing the cards” to “read them into their “memory”.

But these sorts of cheats are often not used in “money games” but “status games” to get bragging and similar points.

In bridge for instance it’s known that pairs of players will use vocal and finger codes to pass information from player to player thus enabling rigged bids etc. It’s where the word “finessing” passed into Cryptography terminology from Bridge playing at Bletchley Park during WWII.

You’re saying the rigged machines reported the final order of the cards, right, not that they influenced it? I first read it as saying the order generated was the same each time, and that obviously doesn’t work (players would notice), and going back I see that’s not what you said.

I guess that this can be seen as additional evidence for the claim that poker is a game of skill (a claim I think I first noticed in Heinlein’s Glory Road). Though not in the sense that Oscar Gordon meant.
