Modern slot machines develop an unbreakable hold on many players—some of whom wind up losing their jobs, their families, and even, as in the case of Scott Stevens, their lives. 
 
 On the morning of Monday, August 13, 2012, Scott Stevens loaded a brown hunting bag into his Jeep Grand Cherokee, then went to the master bedroom, where he hugged Stacy, his wife of 23 years. “I love you,” he told her. Stacy thought that her husband was off to a job interview followed by an appointment with his therapist. Instead, he drove the 22 miles from their home in Steubenville, Ohio, to the Mountaineer Casino, just outside New Cumberland, West Virginia. He used the casino ATM to check his bank-account balance: $13,400. He walked across the casino floor to his favorite slot machine in the high-limit area: Triple Stars, a three-reel game that cost $10 a spin. Maybe this time it would pay out enough to save him. It didn’t. He spent the next four hours burning through $13,000 from the account, plugging any winnings back into the machine, until he had only $4,000 left. Around noon, he gave up. Stevens, 52, left the casino and wrote a five-page letter to Stacy. A former chief operating officer at Louis Berkman Investment, he gave her careful financial instructions that would enable her to avoid responsibility for his losses and keep her credit intact: She was to deposit the enclosed check for $4,000; move her funds into a new checking account; decline to pay the money he owed the Bellagio casino in Las Vegas; disregard his credit-card debt (it was in his name alone); file her tax returns; and sign up for Social Security survivor benefits. He asked that she have him cremated. He wrote that he was “crying like a baby” as he thought about how much he loved her and their three daughters. “Our family only has a chance if I’m not around to bring us down any further,” he wrote. “I’m so sorry that I’m putting you through this.” 
 
 He placed the letter and the check in an envelope, drove to the Steubenville post office, and mailed it. Then he headed to the Jefferson Kiwanis Youth Soccer Club. He had raised funds for these green fields, tended them with his lawn mower, and watched his daughters play on them. Stevens parked his Jeep in the gravel lot and called Ricky Gurbst, a Cleveland attorney whose firm, Squire Patton Boggs, represented Berkman, where Stevens had worked for 14 years—until six and a half months earlier, when the firm discovered that he had been stealing company funds to feed his gambling habit and fired him. Stevens had a request: “Please ask the company to continue to pay my daughters’ college tuition.” He had received notification that the tuition benefit the company had provided would be discontinued for the fall semester. Failing his daughters had been the final blow. Gurbst said he would pass along the request. Then Stevens told Gurbst that he was going to kill himself. “What? Wait.” “That’s what I’m going to do,” Stevens said, and promptly hung up. He next called J. Timothy Bender, a Cleveland tax attorney who had been advising him on the IRS’s investigation into his embezzlement. Up until that point, he had put on a brave face for Bender, saying he would accept responsibility and serve his time. Now he told Bender what he was about to do. Alarmed, Bender tried to talk him out of it. “Look, this is hard enough,” Stevens said. “I’m going to do it.” Click. 
 
 At 4:01 p.m., Stevens texted Stacy. “I love you.” He then texted the same message to each of his three daughters in succession. He took off his glasses, his glucose monitor, and his insulin pump—Stevens was a diabetic—and tucked them neatly into his blue thermal lunch bag with the sandwich and apple he hadn’t touched. He unpacked his Browning semiautomatic 12-gauge shotgun, loaded it, and sat on one of the railroad ties that rimmed the parking lot. Then he dialed 911 and told the dispatcher his plan. Scott Stevens hadn’t always been a gambler. A native of Rochester, New York, he earned a master’s degree in business and finance at the University of Rochester and built a successful career. He won the trust of the steel magnate Louis Berkman and worked his way up to the position of COO in Berkman’s company. He was meticulous about finances, both professionally and personally. When he first met Stacy, in 1988, he insisted that she pay off her credit-card debt immediately. “Your credit is all you have,” he told her. They married the following year, had three daughters, and settled into a comfortable life in Steubenville thanks to his position with Berkman’s company: a six-figure salary, three cars, two country-club memberships, vacations to Mexico. Stevens doted on his girls and threw himself into causes that benefited them. In addition to the soccer fields, he raised money to renovate the middle school, to build a new science lab, and to support the French Club’s trip to France. He spent time on weekends painting the high-school cafeteria and stripping the hallway floors. 
 
 Stevens got his first taste of casino gambling while attending a 2006 trade show in Las Vegas. On a subsequent trip, he hit a jackpot on a slot machine and was hooked. Scott and Stacy soon began making several trips a year to Vegas. She liked shopping, sitting by the pool, even occasionally playing the slots with her husband. They brought the kids in the summer and made a family vacation of it by visiting the Grand Canyon, the Hoover Dam, and Disneyland. Back home, Stevens became a regular at the Mountaineer Casino. Over the next six years, his gambling hobby became an addiction. Though he won occasional jackpots, some of them six figures, he lost far more—as much as $4.8 million in a single year. Did Scott Stevens die because he was unable to rein in his own addictive need to gamble? Or was he the victim of a system carefully calibrated to prey on his weakness? Stevens methodically concealed his addiction from his wife. He handled all the couple’s finances. He kept separate bank accounts. He used his work address for his gambling correspondence: W-2Gs (the IRS form used to report gambling winnings), wire transfers, casino mailings. Even his best friend and brother-in-law, Carl Nelson, who occasionally gambled alongside Stevens, had no inkling of his problem. “I was shocked when I found out afterwards,” he says. “There was a whole Scott I didn’t know.” When Stevens ran out of money at the casino, he would leave, write a company check on one of the Berkman accounts for which he had check-cashing privileges, and return to the casino with more cash. He sometimes did this three or four times in a single day. His colleagues did not question his absences from the office, because his job involved overseeing various companies in different locations. By the time the firm detected irregularities and he admitted the extent of his embezzlement, Stevens—the likable, responsible, trustworthy company man—had stolen nearly $4 million. 
 
 Stacy had no idea. In Vegas, Stevens had always kept plans to join her and the girls for lunch. At home, he was always on time for dinner. Saturday mornings, when he told her he was headed into the office, she didn’t question him—she knew he had a lot of responsibilities. So she was stunned when he called her with bad news on January 30, 2012. She was on the stairs with a load of laundry when the phone rang. “Stace, I have something to tell you.” She heard the burden in his voice. “Who died?” “It’s something I have to tell you on the phone, because I can’t look in your eyes.” He paused. She waited. “I might be coming home without a job today. I’ve taken some money.” “For what?” “That doesn’t matter.” “How much? Ten thousand dollars?” “No.” “More? One hundred thousand?” “Stace, it’s enough.” Stevens never did come clean with her about how much he had stolen or about how often he had been gambling. Even after he was fired, Stevens kept gambling as often as five or six times a week. He gambled on his wedding anniversary and on his daughters’ birthdays. Stacy noticed that he was irritable more frequently than usual and that he sometimes snapped at the girls, but she figured that it was the fallout of his unemployment. When he headed to the casino, he told her he was going to see his therapist, that he was networking, that he had other appointments. When money appeared from his occasional wins, he claimed that he had been doing some online trading. While they lived off $50,000 that Stacy had in a separate savings account, he drained their 401(k) of $150,000, emptied $50,000 out of his wife’s and daughters’ ETrade accounts, maxed out his credit card, and lost all of a $110,000 personal loan he’d taken out from PNC Bank. 
 
 Stacy did not truly understand the extent of her husband’s addiction until the afternoon three police officers showed up at her front door with the news of his death. Afterward, Stacy studied gambling addiction and the ways slot machines entice customers to part with their money. In 2014, she filed a lawsuit against both Mountaineer Casino and International Game Technology, the manufacturer of the slot machines her husband played. At issue was the fundamental question of who killed Scott Stevens. Did he die because he was unable to rein in his own addictive need to gamble? Or was he the victim—as the suit alleged—of a system carefully calibrated to prey upon his weakness, one that robbed him of his money, his hope, and ultimately his life? Less than 40 years ago, casino gambling was illegal everywhere in the United States outside of Nevada and Atlantic City, New Jersey. But since Congress passed the Indian Gaming Regulatory Act in 1988, tribal and commercial casinos have rapidly proliferated across the country, with some 1,000 now operating in 40 states. Casino patrons bet more than $37 billion annually—more than Americans spend to attend sporting events ($17.8 billion), go to the movies ($10.7 billion), and buy music ($6.8 billion) combined. The preferred mode of gambling these days is electronic gaming machines, of which there are now almost 1 million nationwide, offering variations on slots and video poker. Their prevalence has accelerated addiction and reaped huge profits for casino operators. A significant portion of casino revenue now comes from a small percentage of customers, most of them likely addicts, playing machines that are designed explicitly to lull them into a trancelike state that the industry refers to as “continuous gaming productivity.” (In a 2010 report, the American Gaming Association, an industry trade group, claimed that “the prevalence of pathological gambling … is no higher today than it was in 1976, when Nevada was the only state with legal slot machines. And, despite the popularity of slot machines and the decades of innovation surrounding them, when adjusted for inflation, there has not been a significant increase in the amount spent by customers on slot-machine gambling during an average casino visit.”) 
 
 “The manufacturers know these machines are addictive and do their best to make them addictive so they can make more money,” says Terry Noffsinger, the lead attorney on the Stevens suit. “This isn’t negligence. It’s intentional.” Noffsinger, 72, has been here before. A soft-spoken personal-injury attorney based in Indiana, he has filed two previous lawsuits against casinos. In 2001, he sued Aztar Indiana Gaming, of Evansville, on behalf of David Williams, then 51 years old, who had been an auditor for the State of Indiana. Williams began gambling after he received a $20 voucher in the mail from Casino Aztar. He developed a gambling addiction that cost him everything, which in his case amounted to about $175,000. Noffsinger alleged that Aztar had violated the 1970 Racketeer Influenced and Corrupt Organizations Act by engaging in a “pattern of racketeering activity”—using the mail to defraud Williams with continued enticements to return to the casino. But the U.S. District Court for the Southern District of Indiana granted summary judgment in favor of Aztar, and the U.S. Court of Appeals for the Seventh Circuit instructed the district court to dismiss the case, declaring, “Even if the statements in these communications could be considered ‘false’ or ‘misrepresentations,’ it is clear that they are nothing more than sales puffery on which no person of ordinary prudence and comprehension would rely.” 
 
 Four years later, Noffsinger filed a suit on behalf of Jenny Kephart, then 52 years old, against Caesars Riverboat Casino, in Elizabeth, Indiana, alleging that the casino, aware that Kephart was a pathological gambler, knowingly enticed her into gambling in order to profit from her addiction. Kephart had filed for bankruptcy after going broke gambling in Iowa, and moved to Tennessee. But after she inherited close to $1 million, Caesars began inviting her to the Indiana riverboat casino, where she gambled away that inheritance and more. When the casino sued her for damages on the money she owed, Kephart countersued. She denied the basis of the Caesars suit on numerous grounds, including that by giving her “excessive amounts of alcohol … and then claiming that it was injured by her actions or inactions,” Caesars waived any claim it might have had for damages under Indiana law. Although Kephart ultimately lost her countersuit, the case went all the way to the Indiana Supreme Court, which ruled in 2010 that the trial court had been mistaken in denying Caesars’s motion to dismiss her counterclaim. “The existence of the voluntary exclusion program,” the judge wrote, referring to the option Indiana offers people to ban themselves from casinos in the state, “suggests the legislature intended pathological gamblers to take personal responsibility to prevent and protect themselves against compulsive gambling.” (Caesars did not respond to repeated requests for comment.) 
 
 Noffsinger had been planning to retire before he received Stacy Stevens’s phone call. But after hearing the details of Scott Stevens’s situation—which had far more serious consequences than his previous two cases—he eventually changed his mind. Unlike in his earlier gambling cases, however, he decided to include a products-liability claim in this one, essentially arguing that slot machines are knowingly designed to deceive players so that when they are used as intended, they cause harm. In focusing on the question of product liability, Noffsinger was borrowing from the rule book of early antitobacco litigation strategy, which, over the course of several decades and countless lawsuits, ultimately succeeded in getting courts to hold the industry liable for the damage it wrought on public health. Noffsinger’s hope was to do the same with the gambling industry. When Noffsinger filed the Stevens lawsuit, John W. Kindt, a professor of business and legal policy at the University of Illinois at Urbana-Champaign, described it as a potential “blockbuster case.” Even by the estimates of the National Center for Responsible Gaming, which was founded by industry members, 1.1 to 1.6 percent of the adult population in the United States—approximately 3 million to 4 million Americans—has a gambling disorder. That is more than the number of women living in the U.S. with a history of breast cancer. The center estimates that another 2 to 3 percent of adults, or an additional 5 million to 8 million Americans, meets some of the American Psychiatric Association’s criteria for addiction but have not yet progressed to the pathological, or disordered, stage. Others outside the industry estimate the number of gambling addicts in the country to be higher. 
 
 Such addicts simply cannot stop themselves, regardless of the consequences. “When you’re dealing with an addict active in their addiction, they’ve lost all judgment,” says Valerie Lorenz, the author of Compulsive Gambling: What’s It All About? “They can’t control their behavior.” Gambling is a drug-free addiction. Yet despite the fact that there is no external chemical at work on the brain, the neurological and physiological reactions to the stimulus are similar to those of drug or alcohol addicts. Some gambling addicts report that they experience a high resembling that produced by a powerful drug. Like drug addicts, they develop a tolerance, and when they cannot gamble, they show signs of withdrawal such as panic attacks, anxiety, insomnia, headaches, and heart palpitations. Approximately 3 million to 4 million Americans are pathological gamblers—and one in five gambling addicts attempts suicide. Neuroscientists have discovered characteristics that appear to be unique to the brains of addicts, particularly in the dopaminergic system, which includes reward pathways, and in the prefrontal cortex, which exerts executive control over impulses. “We’ve seen a disregulated reward system,” says Jon Grant, a professor in the department of psychiatry and behavioral neuroscience at the University of Chicago. “The frontal parts of the brain that tell us ‘Hey, stop!’ are less active, and parts that anticipate rewards tend to be stronger.” 
 
 Gambling addicts may have a genetic predisposition, though a specific marker has not yet been uncovered. Environmental factors and personality traits—a big gambling win within the past year, companions who gamble regularly, impulsivity, depression—may also contribute to the development of a gambling problem. Whatever the causes, there’s widespread agreement that certain segments of the population are simply more vulnerable to addiction. “You can’t turn on and turn off certain activities of the brain,” says Reza Habib, a psychology professor at Southern Illinois University. “It’s an automatic physiological response.” Scott Stevens’s story is not anomalous. Given the guilt and shame involved, gambling addiction frequently progresses to a profound despair. The National Council on Problem Gambling estimates that one in five gambling addicts attempts suicide—the highest rate among addicts of any kind. There are no accurate figures for suicides related to gambling problems, but there are ample anecdotes: the police officer who shot himself in the head at a Detroit casino; the accountant who jumped to his death from a London skyscraper in despair over his online-gambling addiction; the 24-year-old student who killed himself in Las Vegas after losing his financial-aid money to gambling; and, of course, Stevens himself. 
 
 The Vorhees 
 
 Problem gamblers are worth a lot of money to casinos. According to some research, 20 percent of regular gamblers are problem or pathological gamblers. Moreover, when they gamble, they spend—which is to say, lose—more than other players. At least nine independent studies demonstrate that problem gamblers generate anywhere from 30 to 60 percent of total gambling revenues. 
 
 Casinos know exactly who their biggest spenders are. According to a 2001 article in Time magazine, back in the 1990s casino operators bought records from credit-card companies and mailing lists from direct-mail marketers. One of the latter, titled the “Compulsive Gamblers Special,” promised to deliver the names of 200,000 people with “unquenchable appetites for all forms of gambling.” The casinos used these records and lists to target compulsive gamblers—as Caesars was alleged to have done with Jenny Kephart. These days, the casinos have their own internal methods for determining who their most attractive customers are. According to Natasha Dow Schüll, an NYU professor who spent more than 15 years researching the industry, culminating in her 2012 book, Addiction by Design: Machine Gambling in Las Vegas, 70 percent of patrons now use loyalty cards, which allow the casinos to track such data points as how frequently they play electronic gaming machines, how long they play, how much they bet, how often they win and lose, what times of day they visit, and so on. Each time a patron hits the Spin or the Deal button, which can be as frequently as 900 to 1,200 times an hour, the casino registers the data. Even gamblers who choose to forgo loyalty cards do not necessarily escape the casino’s watchful eye. In some machines, miniature cameras watch their faces and track their playing behavior. 
 
 Several companies supply casinos with ATMs that allow patrons to withdraw funds through both debit and cash-advance functions, in some cases without ever leaving the machines they are playing. (Some of the companies also sell information on their ATM customers to the casinos.) “The whole premise of the casino is to get people to exceed their limits,” says Les Bernal, the national director of the advocacy organization Stop Predatory Gambling. “If you’re using the casino ATM, it’s like painting yourself orange.” All of these data have enabled casinos to specifically target their most reliable spenders, primarily problem gamblers and outright addicts. Despite those customers’ big losses—or rather, because of their losses—the casinos lure them to return with perks that include complimentary drinks and meals, limo service, freebies from the casino gift shop, golf excursions for their nongambling spouses, and in some cases even first-class airfare and suites in five-star hotels. They also employ hosts who befriend large spenders and use special offers to encourage them to stay longer or return soon. Some hosts receive bonuses that are tied to the amount customers spend beyond their expected losses, which are calculated using the data gathered from previous visits. As Richard Daynard, a law professor at Northeastern University and the president of the Public Health Advocacy Institute, explained at the group’s forum on casino gambling in the fall of 2014, “The business plan for casinos is not based on the occasional gambler. The business plan for casinos is based on the addicted gambler.” 
 
 Casinos have developed formulas to calculate the “predicted lifetime value” of any given individual gambler. Gamblers are assigned value rankings based on this amount; the biggest losers are referred to as “whales.” These gamblers become the casinos’ most sought-after repeat customers, the ones to whom they market most aggressively with customized perks and VIP treatment. Caroline Richardson, for example, became a whale for the Ameristar Casino in Council Bluffs, Iowa. In 2011 alone, she lost nearly $2 million, primarily on the casino’s slot machines. The casino allegedly allowed her to go behind the cashier’s “cage,” an area normally off-limits to patrons, to collect cash to gamble. It increased the limits on some slot machines so that she could spend more on single games. It also made a new machine off-limits to other customers so that Richardson could be the first to play it. Management assigned Richardson an executive host, who offered her free drinks, meals, hotel stays, and tickets to entertainment events. So claimed a suit brought against the casino by Richardson’s employer, Colombo Candy & Tobacco Wholesale. Richardson, the company’s controller, embezzled $4.1 million over the course of two years to support her gambling addiction. (In 2014, Richardson, then 54, was sentenced to 14 to 20 years in prison for the crime.) The thefts ultimately put the company out of business. The suit claimed that the casino had ample reason to presume that Richardson, who earned about $62,000 a year, had come into the money she gambled by fraudulent means. (A representative for Ameristar Casino declined to comment on the lawsuit.) 
 
 The U.S. District Court for Nebraska agreed that Colombo had sufficiently proved its initial claim of unjust enrichment, which the casino would have to defend itself against. The suit, however, stalled when Colombo’s president and CEO, Monte Brown, and his wife, Jenise, ran out of money to pay their attorneys and had to file for personal bankruptcy. “They found someone who had the addiction and the ability to steal, and they exploited it,” Monte Brown says. “The casino embezzled from us through an employee.” Jenise adds, “For people to do that to other people, it’s evil.” Clay Rodery Walk into the Mountaineer Casino in West Virginia, and the slot machines overwhelm you—more than 1,500 of them, lights blinking, animated screens flashing, the simulated sound of clinking coins blaring across the floor. The machines have names such as King Midas, Rich Devil, Cash Illusions, Titanic, and Wizard of Oz. It’s a Tuesday afternoon, and here inside the windowless, clockless, cavernous space, a few patrons are clustered around a craps table, a roulette table, and a handful of card tables. But the vast majority sit at the slot machines. Slots and video poker have become the lifeblood of the American casino. They generate nearly 70 percent of casino revenues, according to a 2010 American Gaming Association report, up from 45 percent four decades ago. Three out of five casino visitors say their favorite activity is playing electronic gaming machines. Their popularity spells profits not only for casinos but for manufacturers as well. International Game Technology, which, as the world’s largest manufacturer of slot machines, has made many of the 900,000-plus slot machines in the U.S., earned $2.1 billion in revenues in fiscal year 2014. (That year, Gtech, an Italian lottery company, acquired IGT and adopted its name in a $6.4 billion deal.) 
 
 These are not your grandma’s one-armed bandits. Today’s electronic gaming machines, or EGMs, feature highly sophisticated computers driven by complex algorithms. Old-fashioned three-reel slot machines consisted of physical reels that were set spinning by the pull of a lever. Each reel would have, for example, 22 “stops”: 11 different symbols, and 11 blank spaces between the symbols, for a total of 10,648 possible combinations. If the same symbol aligned on the payline on all three reels when they stopped spinning, the player would win a jackpot that varied in size depending on the symbol. The odds were straightforward and not terribly hard to calculate. The big breakthrough in slots technology was the invention of “virtual reel mapping” in 1982. According to NYU’s Schüll, about 20 to 30 percent of slot machines today resemble the old-fashioned ones, with physical spinning reels. But where each reel stops is no longer determined by the force of a good pull of the lever. Rather, a computer chip within the machine chooses an outcome using “virtual reels,” which may include different quantities of the various symbols—more blank spaces, for instance, and fewer symbols for big jackpots. The physical reels are not spinning until they run out of momentum, as it might appear. Rather, the chips “tell” them where to stop the moment a customer pulls the lever or pushes the button. Thus it is possible for game designers to reduce the odds of hitting a big jackpot from 1 in 10,648 to 1 in 137 million. Moreover, it is almost impossible for a slots player to have any idea of the actual odds of winning any jackpot, however large or small. 
 
 Virtual reel mapping has also enabled a deliberately misleading feature, the “near miss.” That’s when a jackpot symbol appears directly above or below the payline. The intent is to give the player the impression of having almost won—when, in fact, he or she is no closer to having won than if the symbol had not appeared on the reel at all. Some slot machines are specifically programmed to offer up this near-miss result far more often than they would if they operated by sheer chance, and the psychological impact can be powerful, leading players to think, I was so close. Maybe next time. (As I. Nelson Rose, a professor at Whittier Law School and the author of Gambling and the Law, has written, Nevada regulations operate on the theory that a sophisticated player would be able to tell the real odds of winning by playing a machine long enough. The gambling industry maintains that deceptive near misses do not occur in North American gaming machines, but as Schüll has noted, it has developed a more narrow definition of deceptive near misses, which still allows for “subliminal inducements.”) “The business plan for casinos is not based on the occasional gambler. The business plan for casinos is based on the addicted gambler.” Research has shown that an elevated number of near-miss results does increase playing time. Indeed, as early as 1953, B. F. Skinner, the godfather of modern behaviorism, noted, “ ‘Almost hitting the jack pot’ increases the probability that the individual will play the machine.” This effect is even stronger for gambling addicts, whose brains respond to near misses more like wins than like losses. “The near misses [trigger] the same brain response as a win,” says Reza Habib, the Southern Illinois University psychology professor. 
 
 Yet another feature made possible by virtual reel mapping is the uneven distribution of winning symbols among virtual reels, known as “starving reels.” For instance, a 7 may come up four times on the first virtual reel and five times on the second but only once on the third. The first two reels are thus much more likely to hit a 7 than the last one, but you wouldn’t know this by looking at the physical reels. Just as the craps player expects the dice to be numbered 1 to 6 and the blackjack player expects the dealer to use conventional decks of 52 cards, it’s natural for the slot-machine player to expect equal odds on each of the reels, says Roger Horbay, a former gambling-addiction therapist and an expert on electronic gaming machines. “Unbalanced reel design enables EGMs to present to the player screens which are rich in symbols but which are designed to limit winning combinations in a manner incommensurate with the appearance of the screen,” Horbay writes in “Unbalanced Reel Gaming Machines,” a paper he co-authored with Tim Falkiner in 2006. Astonishingly, the patent application for virtual reel mapping, the technology that made all these deceptive practices possible, was straightforward about its intended use: “It is important,” the application stated, “to make a machine that is perceived to present greater chances of payoff than it actually has within the legal limitations that games of chance must operate.” Countries such as Australia and New Zealand have outlawed virtual reel mapping because of the harm the inherent deception inflicts upon players. 
 
 In the United States, by contrast, the federal government granted the patent for virtual reel mapping in 1984. IGT purchased the rights to it in 1989 and later licensed the patent to other companies. “Imagine sitting around a boardroom table, thinking of what’s fair, and coming up with this,” says Kevin Harrigan, a co-director of a gambling-research lab at the University of Waterloo, in Ontario. “It just seems wrong to me.” The Nevada State Gaming Control Board approved virtual-reel slot machines in 1983. Interestingly, during hearings on the subject, Ray Pike, the attorney representing IGT—the very company that would subsequently buy the rights to the patent for virtual reel mapping and manufacture hundreds of thousands of slot machines—called these overrepresented near misses “false advertising,” adding, “There is a deception involved with this kind of a machine.” Yet he also stated that if the board approved virtual reel mapping, “certainly we would like to be able to do that”—create the appearance of near misses above and below the payline—“because I think that is a competitive advantage.” Of course, classic, spinning-reel slot machines make up only a fraction of the electronic gaming machines available at most casinos. Technology has evolved such that many machines lack physical reels altogether, instead merely projecting the likenesses of spinning symbols onto a video screen. These machines allow “multiline” play, an innovation that became common in the 1990s. Instead of betting on one simple payline, players are able to bet on multiple patterns of paylines—as many as 200 on some machines. This allows for more opportunities to win, but the results are often deceptive. For instance, if you bet $1 on each of five different patterns and then get a $3 payout on one pattern, the machine will treat you like a winner, with flashing lights and congratulatory videos and the requisite clinking of virtual coins. The reality, of course, is that you have lost $2. 
 
 “The brain somehow registers a win,” Kevin Harrigan says. “No matter what you think, physically you’re being affected by these things—the lights, the sounds, the graphics—as a win. You can get 150 to 200 of these false wins, which we also call losses, an hour. That’s a lot of positive reinforcement.” Losses disguised as wins also create a “smoother ride,” as some within the industry call it, allowing a machine to slowly deplete a player’s cash reserves, rather than taking them in a few large swipes. Because the machine is telling the player he or she is winning, the gradual siphoning is less noticeable. Related to the video slot machines are video-poker terminals, which IGT began popularizing in 1979. The standard five-card-draw game shows five cards, each offering players the option to hold or replace by drawing a card from the 47 remaining in the virtual deck. The games require more skill—or at least a basic understanding of probabilities—than the slot machines do. As such, they appeal to people who want to have some sense of exerting control over the outcome. But over time, designers of video-poker machines discovered that they could influence gamblers’ behavior by manipulating game details. They saw, for instance, patrons going more often for four of a kind than the royal flush, a rarer but more lucrative hand, and they adjusted the machines accordingly. Video poker also offers its own version of losses disguised as wins. Today’s “multihand” video-poker machines—triple-play, 10-play, and even 100-play—allow patrons to play multiple hands simultaneously. This creates an experience similar to multiline slots, in which players are likely to “win back” a portion of each bet by frequently hitting small pots even as they are steadily losing money overall. ||||| Whiting estimates the number of successful advantage players to be in the hundreds. Cumulatively, they rake in large profits from games that were designed to be unbeatable: While some bettors might get lucky and win in the short run, over time they are supposed to lose and the casinos are expected to win, statistically speaking. In recent years, however, Whiting says the ranks of advantage players have swelled. Several factors are responsible. One is the ease with which gamblers can find each other online and share tactics. Grosjean has a blog called Beyond Numbers, for example. Another is the proliferation of books like Grosjean’s “Beyond Counting,” which he published in 2000 and updated in 2009 as a self-published edition (though he claims that if he doesn’t know who you are, he won’t sell you a copy). And because regulated casino gambling now takes place in at least 40 states, casinos compete for customers in part by introducing new games, some of which turn out to be vulnerable. 
 
 Common advantage-play techniques include “hole carding,” in which sharp-eyed players profit from careless dealers who unwittingly reveal tiny portions of the cards; “shuffle tracking,” or memorizing strings of cards in order to predict when specific cards will be dealt after they are next shuffled; and counting systems that monitor already dealt cards in order to estimate the value of those that remain in the deck. Richard Munchkin, a professional gambler who is the author of “Gambling Wizards” and a co-host of the radio show “Gambling With an Edge,” claims to have mastered all of these techniques. “I think every game can be beaten,” he says. (Munchkin, whose real first name is Richard, chose his professional surname because of the fact that he stands slightly taller than five feet.) “For example, certain slot machines must pay off their jackpots once they have accumulated $30,000. At $28,000, a slot machine might be a play” — gambling argot for something that can be bet on advantageously — “and there are slot teams that specialize in this. I know people who clock roulette wheels and others who can control a single die at craps.” 
 
 Among the most susceptible games these days are blackjack and poker variations like Ultimate Texas Hold ’Em, in which play is against the house rather than other gamblers. Teams of advantage players — which usually require one person to bet and another to spot dealers’ hole cards (those turned down and not supposed to be seen), track shuffles or count cards — have become so prevalent that they often find themselves in the same casino, at the same time, targeting the same game. “We had a blackjack game in Atlantic City with a weak dealer,” recalls Bobby Sanchez, known as the Bullet, a frequent playing partner of Grosjean’s. “We had our key seats locked up when players from two other crews tried jumping into the game. Elbows were thrown and there was a lot of jostling around the table. An older civilian accidentally got in the middle of it. His son thought I had hit him, and the son jumped on my back.” Things ultimately calmed down and an agreement was reached via surreptitious cellphone conversations: Members from the other teams would be able to sit and play at the table and use information from Sanchez’s spotter, but their betting would be capped at $800 per hand. “Meanwhile I bet three hands of $3,000 each,” Sanchez says. “Unfortunately, the dealer got pulled out after about 90 minutes. Following all the tumult, the table was being watched and somebody figured out what was going on. Still, we managed to win around $100,000 that night.” 
 
 One Friday night I accompanied the slimly built Grosjean, who wore baggy jeans, a red polo shirt and a hat with its bill riding low, as he strolled across the carpeted mezzanine of the Potawatomi Indian tribe’s Grand Casino Hotel and Resort in Shawnee. As I walked beside him, I tried to appear casual, with the tail of my untucked shirt covering the notepad in the back pocket of my slacks. 
 
 Grosjean passed an escalator and headed down a back staircase. To experienced surveillance people, he is a known advantage player; at any time he could be spotted, matched to his picture in a database of such players and asked to leave a casino. If that happens, the security guard could also read him the trespass act, meaning Grosjean would risk arrest if he tried to return. Getting away, on the other hand, would give him an opportunity to come back on some future day and perhaps go unnoticed. So if security was waiting for him at the bottom, Grosjean needed to be able to run back up in the opposite direction with the hope of avoiding a confrontation. He couldn’t do that on an escalator. 
 
 Down below on the gaming floor, ringed by wall-mounted TV monitors silently showing a sporting event, slot machines chirped and crowded blackjack tables buzzed with action. Grosjean sidestepped a cocktail waitress and approached the casino’s only craps game, the one in which cards are used instead of dice. 
 
 Grosjean had explained earlier the reason for this quirk: The Grand happens to be located in a jurisdiction where it is illegal for dice to determine financial outcomes in games of chance. Two sets of six playing cards, numbered one through six, one set with red backs, the other with blue backs, serve as de facto dice. A player rolls a giant numbered cube, apparently made from plastic foam. The cube determines which cards are turned over. It is a way to make the game feel like craps without dice directly producing a monetary outcome. 
 
 After that, standard rules apply. A gambler might bet, for example, that the sum of the first two cards in play will total 7 or 11. If the sum equals 2, 3 or 12, he loses. If 4, 5, 6, 8, 9 or 10 come up, a “point” is established, and he wins if subsequent cards add up to that number. If a total of 7 comes first, he loses. Over the course of the game, players can wager on other combinations, like two 5s turned over (which pays out 7 to 1). Such proposition, or prop, bets favor the casino. After every two-card set is turned over, the cards were machine-shuffled before the next roll.
– What was Michael Phelps doing before he was arrested on DUI charges early yesterday? According to TMZ and its "casino sources," he was on an eight-hour "gambling binge." The sources say Phelps was playing blackjack and drinking beer in a private VIP room at Baltimore's Horseshoe Casino starting around 5pm Monday; he left around 1am was pulled over around 1:40am a few miles from the casino. He's said to be a regular there, usually playing poker; it's not clear whether he played other card games Monday. Phelps apologized on Twitter yesterday: "I understand the severity of my actions and take full responsibility," he wrote. "I know these words may not mean much right now but I am deeply sorry to everyone I have let down."
