    old article from 1999 but still a very good one

Manziel may only be 6 feet tall, but he has size 15 feet. And he has HUGE hands. I know some NFL scouts so I know what I am talking about.

    This has been discussed here before.

    Obviously this article is obsolete, in that the same tactics could never be used on 2017 sites -- not even the smaller ones.

    At least these guys were ethical enough to report the vulnerability, rather than exploit it.

    Planet Poker was pretty inept. It was the first site I ever played on. I signed on there in January 2001.

    By mid-2001, they made a major blunder and released an update which was broken, and couldn't connect to their server (not even to get future updates). You had to uninstall and reinstall to get it to work again.

    Many people didn't figure this out, and thought the site just went down.

    The traffic fell sharply and never recovered.

    True Poker then took its place as the #2 poker site (behind Paradise Poker). Then Party Poker came on the scene and blew them all away.

    In 2002, Pokerstars launched. By early 2003, it was rapidly gaining steam, and it claimed the #1 spot it would never relinquish.

    I was the #1 limit holdem winner on Pokerstars in 2003. I also held that title on the Boss Media Network in 2005, Absolute Poker in 2007 until August when I quit due to the superuser scandal, and Bodog in 2010.

    Ahhh... the good old days.

    I didnt even know how to play poker back then..

    But if my current poker status is any small indication,, it must have been great back then..

    Im actually offended if i dont have a winning session right now..lol..

    But then again , i only make notes. No huds or seat scripters or angle shooting bum hunting. I just sit and try to out play my opponent (honestly)

    Check it out druff... lol if people think things like what is discussed in the article are not going on or being attempted with/on online poker/gaming sites.

    "But Alex couldn’t just cash out as if he owned an ordinary startup because his business operates in murky legal terrain. The venture is built on Alex’s talent for reverse engineering the algorithms—known as pseudorandom number generators, or PRNGs—that govern how slot machine games behave. Armed with this knowledge, he can predict when certain games are likeliest to spit out money—insight that he shares with a legion of field agents who do the organization’s grunt work.
    These agents roam casinos from Poland to Macau to Peru in search of slots whose PRNGs have been deciphered by Alex. They use phones to record video of a vulnerable machine in action, then transmit the footage to an office in St. Petersburg. There, Alex and his assistants analyze the video to determine when the games’ odds will briefly tilt against the house. They then send timing data to a custom app on an agent’s phone; this data causes the phones to vibrate a split second before the agent should press the “Spin” button. By using these cues to beat slots in multiple casinos, a four-person team can earn more than $250,000 a week."



    "Alex also claims to be engaged in selling his milking system to interested parties. One of his customers, he says, was a New York-based crew of alleged Russian and Georgian mafiosi, 33 of whom were indicted in June for racketeering, fraud, and other crimes. According to confidential government informants, this crew, known as the Shulaya Enterprise, brought an Aristocrat Mark VI slot machine to a Brooklyn aparment in September 2016; four months later, the group began fleecing casinos in Pennsylvania by using “electronic devices and software designed to predict the behavior of particular models of electronic slot machines.”


    https://www.wired.com/2017/02/russia...asinos-no-fix/


    Recognizing those patterns would require remarkable effort. Slot machine outcomes are controlled by programs called pseudorandom number generators that produce baffling results by design. Government regulators, such as the Missouri Gaming Commission, vet the integrity of each algorithm before casinos can deploy it.
    But as the “pseudo” in the name suggests, the numbers aren't truly random. Because human beings create them using coded instructions, PRNGs can't help but be a bit deterministic. (A true random number generator must be rooted in a phenomenon that is not manmade, such as radioactive decay.) PRNGs take an initial number, known as a seed, and then mash it together with various hidden and shifting inputs—the time from a machine’s internal clock, for example—in order to produce a result that appears impossible to forecast. But if hackers can identify the various ingredients in that mathematical stew, they can potentially predict a PRNG’s output. That process of reverse engineering becomes much easier, of course, when a hacker has physical access to a slot machine’s innards.
    Knowing the secret arithmetic that a slot machine uses to create pseudorandom results isn’t enough to help hackers, though. That’s because the inputs for a PRNG vary depending on the temporal state of each machine. The seeds are different at different times, for example, as is the data culled from the internal clocks. So even if they understand how a machine’s PRNG functions, hackers would also have to analyze the machine’s gameplay to discern its pattern. That requires both time and substantial computing power, and pounding away on one’s laptop in front of a Pelican Pete is a good way to attract the attention of casino security.
    The Lumiere Place scam showed how Murat Bliev and his cohorts got around that challenge. After hearing what had happened in Missouri, a casino security expert named Darrin Hoke, who was then director of surveillance at L’Auberge du Lac Casino Resort in Lake Charles, Louisiana, took it upon himself to investigate the scope of the hacking operation. By interviewing colleagues who had reported suspicious slot machine activity and by examining their surveillance photos, he was able to identify 25 alleged operatives who'd worked in casinos from California to Romania to Macau.
