Edge sorting

Edge sorting is an advantage gambling technique primarily employed in card games such as baccarat and punto banco, where players identify subtle, unintentional asymmetries or imperfections in the edge patterns on the backs of playing cards to determine whether a face-down card is of high or low value.^[1]^[2]^[3] This method relies on manufacturing variations in card decks, particularly those from brands like Gemaco, which can create distinguishable differences between the long edges of cards when viewed from the side, allowing skilled players to sort and track valuable cards (such as six through nine in baccarat) without physically handling the deck.^[1]^[2] To execute it effectively, players often request specific conditions, such as using a particular deck and having the dealer rotate cards 180 degrees during dealing—typically under the pretext of superstition—to orient the cards for edge visibility.^[3]^[1] The technique gained widespread notoriety through its use by professional poker player Phil Ivey and his associate Cheung Yin Sun, who applied it in high-stakes sessions in 2012, winning £7.7 million (approximately $10 million) at London's Crockfords Club casino and $9.6 million at the Borgata Hotel Casino in Atlantic City.^[2]^[1]^[3] In both instances, the casinos withheld the winnings, alleging cheating, leading to prolonged legal battles; the UK Supreme Court ruled in 2017 that Ivey's actions constituted cheating under the Gambling Act 2005 by unlawfully altering the game's conditions, even absent overt dishonesty, while the U.S. case against Borgata was settled out of court in 2020 for an undisclosed amount after initial judgments favored the casino.^[2]^[1]^[3]^[4] Legally, edge sorting occupies a gray area in gambling law, viewed by courts as a form of advantage play that exploits casino procedures rather than traditional cheating like marked cards, prompting casinos worldwide to adopt countermeasures such as more symmetric card designs, automatic shufflers, and stricter dealer protocols to prevent its use.^[1]^[3] Despite the controversies, proponents argue it demonstrates exceptional observational skill, blurring the lines between legitimate strategy and impropriety in casino gaming.^[2]

Overview

Definition and Principles

Edge sorting is a technique employed in advantage gambling, primarily in card games such as baccarat and blackjack, where players exploit minute manufacturing imperfections on the backs of playing cards to identify whether a face-down card is of high or low value. These imperfections arise from inconsistencies in the printing and cutting processes, creating asymmetrical patterns along the edges of the cards that are imperceptible to the untrained eye but discernible with careful observation. Unlike traditional card counting, which relies on probability and memory, edge sorting leverages physical defects to gain predictive information about card identities, thereby shifting the odds in the player's favor without altering the cards themselves.^[5]^[6] The core principle of edge sorting hinges on the exploitation of non-uniform card backs, where decorative patterns extend unevenly to the edges due to imprecise manufacturing tolerances. In ideally produced decks, card backs are symmetrical with white borders to mask such flaws, but in defective decks—often used in casinos for cost reasons—the patterns reveal subtle differences when cards are rotated or viewed from specific angles. Players identify "edge markers," such as elongated or shortened motifs on the long edges, to categorize cards into groups; for instance, in baccarat, distinguishing high-value cards (typically 6 through 9) from lower ones is sufficient, as these determine critical outcomes like player or banker wins. This method requires a deck with consistent defects and minimal shuffling to preserve orientations, allowing players to track cards across multiple hands.^[5]^[6] To implement edge sorting, players subtly influence the dealer's handling of cards during the initial sort or cut, often by requesting specific rotations under the guise of superstition—such as asking for cards to be turned 180 degrees if they are "lucky" or aligned in a certain way—without revealing the strategic intent. Once sorted, the asymmetrical edges enable identification during gameplay, enabling informed betting decisions; for example, wagering heavily on the player hand when a high-value card is detected in the shoe. The technique can yield a significant house edge reduction, with estimates suggesting up to a 6.76% player advantage in baccarat under optimal conditions, though success depends on the defect's visibility and the game's rules. This form of advantage play occupies a gray area between skill-based strategies and manipulation, as it uses observable casino-provided materials without external aids.^[5]^[6]

Historical Development

The concept of edge sorting, involving the exploitation of manufacturing asymmetries on the backs of playing cards to identify high-value cards, traces its origins to 19th-century discussions of gambling cheats and protections. In his 1891 book Baccarat Fair and Foul, Professor Hoffmann described various manipulations in baccarat, including techniques that relied on card irregularities visible from the edges, highlighting early awareness among game protectors of such advantage plays in European casinos.^[7] By the mid-20th century, literature on detecting gambling fraud explicitly addressed edge-based card identification. Frank Garcia's 1977 work How to Detect Crooked Gambling, Marked Cards and Loaded Dice (2nd edition, pages 101–103) outlined methods for spotting and countering irregularities in card edges that could reveal values without marking, emphasizing their use in table games like blackjack and baccarat. Similarly, Bill Friedman's 1982 Casino Management (page 44) discussed protective strategies against "first-card knowledge" exploits, indirectly referencing edge imperfections as a known vulnerability in casino operations.^[7] The technique evolved into a formalized advantage play method in the late 20th and early 21st centuries, as casinos increasingly used mass-produced card decks with subtle printing flaws. While not newly invented, edge sorting gained practical refinement through professional gamblers targeting specific card manufacturers, such as those producing asymmetrical patterns on long edges, allowing players to sort decks pre-deal for an informational edge of up to 6% in baccarat. This development was driven by broader advancements in advantage play communities, where such exploits were shared discreetly to avoid countermeasures like card rotation or borderless designs.^[8]

Technique

Card Imperfections and Identification

Edge sorting relies on subtle manufacturing imperfections in the backs of playing cards, which create asymmetrical patterns that can distinguish card orientations when viewed from the edges. These defects typically arise during the printing or cutting process, where decorative elements—such as repeating motifs of circles or diamonds—are not perfectly centered or aligned, resulting in one long edge of the card displaying a different proportion of the pattern compared to the opposite edge. This variation is the same for all cards and is often imperceptible when cards are face up but becomes identifiable from the side when cards are oriented differently.^[9]^[10] The identification process begins with selecting decks known to have exploitable flaws, such as those produced by manufacturers like Gemaco, whose cards featured a purple-backed design with white circles that were asymmetrically cut. Players request the use of these specific decks, often citing preferences for brand or color. During the play of initial hands, after cards are revealed, the player collaborates with an accomplice to instruct the dealer to rotate targeted high-value cards (6-9 in baccarat) 180 degrees during collection—framed as a superstition about card orientation or "good luck"—without alerting the casino to the intent. Low-value cards (A-5 and 10-K, scored 0-5 in baccarat) are left unrotated. This rotation alters the edge presentation based on value: when the card is later dealt face down, the player observes the exposed edges (typically a small portion visible in baccarat) to determine if the asymmetry matches the "high-value" orientation. Automatic shufflers, which preserve card facing and rotation, ensure the orientations carry through the shoe, allowing repeated identification without reshuffling disrupting the setup. In the 2012 Borgata case, Phil Ivey and accomplice Cheung Yin Sun exploited Gemaco cards' defects to identify 6-9s, resulting in a player advantage of approximately 6.765% overall, with up to 21.5% on Player bets and 5.5% on Banker bets, depending on visibility and the identified card's impact.^[8]^[11]^[9]^[12] In the Crockfords case, a similar method was applied to a different deck with comparable imperfections, where Ivey requested high-stakes private play and specific card handling to facilitate edge observation. The technique requires exceptional visual acuity and practice to discern differences as small as 0.5 mm in pattern alignment, often under low-light casino conditions. Courts in both the UK and US have described these imperfections as unintentional manufacturing variances, not deliberate markings, but ruled the deliberate rotation and exploitation as cheating under gaming laws. Success depends on the defect's consistency across the deck; not all cards or brands exhibit usable asymmetries, limiting the method to certain suppliers.^[13]^[14]

Application During Gameplay

Edge sorting is primarily applied in games like baccarat, where players exploit asymmetrical patterns on card backs to identify high-value cards (typically 6 through 9) without physical contact. During gameplay, the technique begins with the player or an accomplice requesting the dealer to orient specific cards in a particular direction, often under the pretext of superstition to avoid suspicion. For instance, in baccarat sessions, the accomplice communicates in a foreign language, such as Mandarin, instructing the dealer to rotate "good" cards (high values) 180 degrees during collection after revelation while leaving "bad" cards (low values) unrotated, ensuring the edge patterns align consistently for later identification.^[12] Once the cards are sorted and placed into the automatic shuffling machine—which preserves their orientation without randomizing rotations—the shoe is prepared for dealing. As cards emerge from the shoe during subsequent hands, the player observes the exposed edge patterns from their position at the table, allowing them to distinguish high from low cards with high accuracy before placing bets. This is particularly effective for identifying the value of the first card dealt, enabling strategic betting on Player or Banker hands to reverse the house edge from approximately 1.06%–1.24% to a player advantage of about 6.76%.^[5]^[15] In practice, as demonstrated in high-stakes baccarat play, the accomplice monitors the edges closely while the primary player, such as Phil Ivey, makes large wagers based on the identified card values, often escalating bets on confirmed high-card outcomes. The method relies on the dealer's compliance during the initial sorting phase and the absence of card rotation in the shuffler, maintaining the exploitable asymmetry throughout multiple rounds until the shoe is depleted. This application requires precise observation and quick decision-making, typically yielding significant wins over repeated sessions without altering the game's rules or using prohibited devices.^[12]

Notable Cases

Phil Ivey at Borgata

In April 2012, professional poker player Phil Ivey contacted the Borgata Hotel Casino & Spa in Atlantic City, New Jersey, to arrange high-stakes baccarat sessions, marking the beginning of a series of visits that employed edge sorting.^[16] Ivey, accompanied by associate Cheung Yin "Kelly" Sun, requested specific conditions to facilitate the technique, including a private gaming pit, a Mandarin-speaking dealer, the use of purple Gemaco playing cards, and an automatic shuffler that preserved card orientation.^[12] During play, Sun directed the dealer to rotate certain cards 180 degrees based on verbal cues in Mandarin—"beautiful" (hao) for high-value cards (6 through 9) and "not beautiful" (bu hao) for others—allowing Ivey to identify card values from their asymmetrical edges when they reappeared in subsequent deals.^[16] This method exploited manufacturing imperfections in the Gemaco cards, granting Ivey an estimated 6.765% advantage over the house's typical 1.06% edge in Punto Banco baccarat by revealing the value of the first card dealt.^[12] Over four sessions in 2012, Ivey won a total of $9.626 million from Borgata.^[16] The first session on April 11 lasted 16 hours with average bets of $25,000, yielding $2.416 million; the second on May 3 spanned 56 hours at $36,000 average bets for $1.597 million; the third on July 17 involved 17 hours at $89,000 average bets, netting $4.788 million; and the fourth in October added $825,000 over 18 hours with $93,800 average bets.^[17] Ivey did not physically handle the cards, adhering to standard baccarat rules, but the coordinated requests and rotations enabled the edge-sorting scheme without detection during the sessions.^[16] Borgata discovered the anomaly after reviewing surveillance footage and card patterns post-sessions, prompting the casino to file a civil lawsuit in May 2014 against Ivey, Sun, and card manufacturer Gemaco Inc. in the U.S. District Court for the District of New Jersey.^[18] The complaint alleged 12 counts, including breach of contract, fraud, civil conspiracy, and violations of the Racketeer Influenced and Corrupt Organizations (RICO) Act, asserting that the edge-sorting constituted cheating under New Jersey gaming regulations (N.J.S.A. § 5:12-115) by deceiving the dealer and manipulating game integrity.^[16] In October 2016, U.S. District Judge Noel L. Hillman ruled in favor of Borgata, finding that Ivey and Sun had breached their implied contract to play fairly and ordering repayment of the full $9.626 million winnings plus $500,000 in accrued interest, totaling over $10 million; however, RICO and fraud claims were dismissed as they did not apply to state-regulated gaming.^[12] Ivey appealed the decision to the U.S. Court of Appeals for the Third Circuit in 2017, arguing that edge sorting was legitimate advantage play akin to card counting, as he had disclosed his preferences to Borgata without violating explicit rules or using devices.^[18] The appeal process extended into 2020, during which Borgata pursued Ivey's assets, including attempts to seize $124,000 from his 2019 World Series of Poker winnings and filings in Nevada courts.^[17] On July 2, 2020, the parties reached a confidential settlement during Third Circuit mediation, vacating the district court's judgment and resolving all related claims, including those against Sun and the Nevada proceedings; specific terms were not disclosed, but the agreement allowed Ivey to resume participation in U.S. poker tournaments without further asset threats.^[18]

Phil Ivey at Crockfords

In August 2012, professional poker player Phil Ivey, accompanied by Cheung Yin Sun, visited Crockfords Club Casino in London, part of Genting Casinos UK Ltd, to play Punto Banco, a variant of baccarat.^[19] They were granted access to a high-stakes private room and requested specific conditions, including the use of eight decks of Angel Playing Cards produced by Angel Co Ltd, a Mandarin-speaking female croupier, and an automatic shuffling machine.^[19] These cards featured minute manufacturing imperfections on their edges, allowing for the identification of high-value cards (6 through 9) when oriented correctly, providing an estimated 6.5% advantage over the house.^[19] During the session starting on August 20, Ivey and Sun employed edge sorting by observing the backs of the cards as they were dealt and directing the croupier, Kathy Yau, to rotate certain cards 180 degrees based on whether Ivey declared them "lucky" or "unlucky," under the pretense of superstition.^[19] Ivey did not handle the cards himself but instructed Sun, who spoke to Yau in Mandarin, to ensure the rotations aligned the asymmetrical patterns for later identification from the edges during subsequent deals.^[19] They also requested that the same shoe of cards be reused across hands, preserving the sorted order until the automatic shuffler was used only at the end of the shoe.^[19] Over two days of play, Ivey staked £1 million and won approximately £7.7 million.^[1] Upon reviewing CCTV footage after the session, Crockfords suspected cheating and refused to pay the winnings on August 30, 2012, instead refunding Ivey's original stake.^[19] Ivey subsequently sued Genting Casinos in the High Court, seeking recovery of the £7.7 million plus interest, arguing that his actions constituted legitimate skill and did not breach any casino rules.^[19] In October 2014, Mr Justice Mitting ruled in favor of the casino, finding that edge sorting amounted to cheating under section 42 of the Gambling Act 2005, as it interfered with the game's required element of chance by effectively sorting the deck in advance.^[19] Ivey appealed to the Court of Appeal, which in November 2016 upheld the High Court's decision by a majority, determining that cheating did not require proof of dishonesty under the objective test applicable to civil claims, though one judge dissented on the need for subjective dishonesty per the criminal standard in R v Ghosh.^[19] The case reached the UK Supreme Court, which in a unanimous judgment on October 25, 2017, dismissed Ivey's final appeal.^[19] The Court clarified that cheating under the Act involves any deliberate act that improperly affects the game's outcome, regardless of dishonesty, and affirmed that Ivey's coordinated deceptions—such as the rotations and card reuse requests—violated the implied contractual term for Punto Banco to be played fairly as a game of chance.^[19] As a result, the casino retained the winnings, marking a significant precedent on the boundaries of advantage play in gambling.^[1]

Legality

Key Legal Rulings

In the landmark case Ivey v Genting Casinos (UK) Ltd t/a Crockfords UKSC 67, the UK Supreme Court unanimously ruled that Phil Ivey's use of edge sorting in Punto Banco (a variant of baccarat) at Crockfords Club constituted cheating under section 42 of the Gambling Act 2005.^[20] The court determined that Ivey's actions—requesting specific card orientations and using an accomplice to identify asymmetrical patterns on card backs—manipulated the dealing process in a way that exploited manufacturing imperfections, thereby gaining an illegitimate advantage not intended by the game's rules.^[20] Although the judgment primarily addressed civil contract law, it clarified that cheating does not require proof of dishonesty under the criminal standard, but in this instance, Ivey's conduct was deemed inherently dishonest by objective standards.^[20] As a result, the casino was not obligated to pay out the £7.7 million in winnings, and the contract was voided, restoring the parties to their pre-gaming positions.^[20] A significant broader impact of the ruling was the overhaul of the test for dishonesty in English law. The Supreme Court rejected the second limb of the R v Ghosh QB 1053 test, which had required assessing whether the defendant realized their actions were dishonest by ordinary standards.^[20] Instead, it established a two-stage objective test: first, ascertaining the facts as the defendant believed them to be; second, evaluating whether those actions would be considered dishonest by reasonable and honest people, without regard to the defendant's subjective belief.^[20] This shift, while originating in a gambling dispute, has since influenced criminal law cases involving fraud and theft.^[20] In the United States, the federal district court in Marina District Development Co., LLC v. Ivey (No. 1:14-cv-02283, D.N.J. 2016) held that Ivey and his associate Cheung Yin Sun breached their implied contract with the Borgata Hotel Casino & Spa by employing edge sorting during high-stakes baccarat sessions in April 2012.^[21] The court found that the technique violated the New Jersey Casino Control Act (N.J.S.A. 5:12-115(a)(2) and (b)), specifically prohibitions against using marked or altered cards, as Ivey's requests for card rotation and pattern identification effectively turned the deck into a marked one, providing "first card knowledge" and skewing the odds.^[21] Although the casino's claims of fraud and Racketeer Influenced and Corrupt Organizations Act violations were dismissed for lack of sufficient evidence of intent to defraud, the breach of contract claim succeeded because the players failed to adhere to the casino's rules and the statutory framework governing gameplay.^[21] The court ordered Ivey and Sun to repay $9.6 million in baccarat winnings plus $500,000 in related craps comps, totaling $10.13 million, to restore the status quo ante.^[21] This ruling emphasized that edge sorting, while not traditional sleight-of-hand cheating, undermined the integrity of regulated casino games by circumventing house rules without altering physical equipment.^[21] Ivey's subsequent appeals were denied, leading to a 2020 settlement where he repaid the amount, though the core legal findings on contract breach and regulatory violation stood.^[18] A related U.S. ruling occurred in Sun v. Mashantucket Pequot Gaming Enterprise, 309 F.R.D. 157 (D. Conn. 2015), involving Cheung Yin Sun's edge sorting during baccarat at Foxwoods Resort Casino in late 2011. The federal district court granted summary judgment for the casino, finding that Sun's technique violated tribal gaming regulations under the Indian Gaming Regulatory Act (25 U.S.C. § 2710) and the Mashantucket Pequot Gaming Procedures, as it involved improper marking of cards through orientation requests. The court denied Sun's claim for $1.148 million in withheld winnings, affirming that such advantage play breached the implied contract and gaming integrity rules.^[22] These rulings from multiple U.S. jurisdictions and the UK have set precedents distinguishing edge sorting from legitimate advantage play, such as card counting, by classifying it as a form of prohibited manipulation.

Ethical Distinctions from Other Methods

Edge sorting occupies a controversial position on the ethical spectrum of gambling advantage techniques, positioned between legitimate skill-based methods like card counting and illicit cheating practices such as marking cards or using hidden devices. Unlike card counting, which relies solely on mental acuity to track visible card values and probabilities without any deception or alteration of game conditions, edge sorting involves deliberate requests to casino staff—often framed as superstitions—to orient cards in ways that exploit manufacturing asymmetries. This element of inducement has led courts to view it as introducing dishonesty, distinguishing it ethically from pure observational skills. For instance, in the proceedings of Ivey v. Genting Casinos, the trial court noted that edge sorting "is quite different from the advantage which may accrue to a punter as a result of counting the cards," classifying it as cheating under civil law due to the manipulative steps taken to fix the deck order.^[5] In contrast to outright cheating, which typically entails active sabotage of the game's integrity—such as physically marking cards, employing sleight of hand, or deploying electronic aids—edge sorting leverages pre-existing imperfections in card production without any physical tampering by the player. Proponents argue this preserves the game's randomness, as the defects are inherent to the equipment provided by the casino, akin to how advantage players might exploit procedural flaws like predictable shuffles. However, legal analyses highlight that the technique's reliance on dealer complicity through misleading instructions crosses an ethical threshold by undermining the implied contract of fair play, even if no statutes explicitly prohibit it. The New Jersey Superior Court in Borgata Hotel Casino & Spa v. Ivey (2016) ruled that edge sorting breached the Casino Control Act by allowing players to "unilaterally adjust the odds of a casino game in [their] favor," in violation of the essential purpose of legalized gambling.^[21]^[12] Ethically, some gambling experts equate edge sorting to other forms of advantage play, asserting that it merely exploits systemic vulnerabilities much like card counting or hole carding, without violating information symmetry through illegal means. Professional poker author Ed Miller, reflecting on Ivey's cases, noted, "I really see very little difference between what Ivey did and what we did [in card counting teams]," framing both as legitimate gamesmanship against casino-imposed edges like the house advantage in baccarat (typically 1.06% for banker bets).^[23] Yet, this perspective remains debated, as edge sorting's requirement for specific accommodations—such as custom card sets or language-specific dealers—introduces a layer of potential collusion that pure skill methods lack, placing it closer to ethical gray areas on the advantage play continuum. Analyses from the International Association of Gaming Advisors position edge sorting squarely in the middle of the advantage play spectrum, creating challenging legal questions due to its intermediate nature between innocent techniques and outright cheating.^[6]

Countermeasures

Casino Detection Strategies

Casinos employ several strategies to detect edge sorting during gameplay, primarily focusing on behavioral cues and procedural anomalies that deviate from standard play. One key method involves training dealers and floor staff to identify suspicious requests from players, such as repeatedly asking for cards to be rotated or turned in specific orientations, which is a hallmark of edge sorting to align imperfections for later identification.^[24] Surveillance teams monitor these interactions in real-time, often using overhead cameras to observe patterns in player-dealer exchanges that could indicate exploitation of card backs.^[24] Another detection approach centers on analyzing betting patterns and win rates. Casinos track deviations from expected outcomes, such as unusually high win streaks in games like baccarat or blackjack, prompting immediate reviews of footage and session data. For instance, in high-stakes sessions, security may flag players who consistently bet large amounts on hands likely to benefit from sorted edges, as seen in investigations following significant payouts.^[6] Internal audits, including post-session reviews of card decks for handling irregularities, further aid detection by correlating player actions with any preserved orientations.^[24] To enhance detection, many casinos integrate technology and procedural checks. Surveillance systems monitor for anomalous behaviors, such as frequent requests for new decks or specific seating arrangements that facilitate edge viewing. Staff are also trained to note accomplices, like interpreters or associates, who may assist in signaling or confirming card identities without direct manipulation.^[6] Once suspected, casinos initiate discreet investigations, reviewing video recordings and player histories to confirm edge sorting before intervening, often resulting in withheld winnings or bans.^[6]

Industry Prevention Measures

Casinos have adopted modified shuffling procedures to counteract edge sorting by randomizing card orientations during the shuffle process. A common technique involves incorporating a "turn," where the dealer rotates one half of the divided deck 180 degrees relative to the other half before interleaving them, ensuring that card backs are not consistently aligned for edge identification. This method disrupts the predictability of edge patterns that players might exploit, and it has become a standard practice in many baccarat games following high-profile incidents. Additionally, some casinos require all bets to be placed before any cards are exposed, preventing players from adjusting wagers based on observed edges during the deal. To address manufacturing imperfections at the source, the industry has shifted toward using decks with symmetric back designs or uniform borders that eliminate exploitable asymmetries. Cards featuring white borders around the pattern or precisely mirrored motifs on opposite edges make it difficult or impossible to distinguish high-value cards from low ones based on edge views alone. These higher-quality decks, though slightly more expensive, are increasingly adopted by casinos to minimize the risk without altering gameplay aesthetics significantly. Technological innovations have also emerged as prevention tools, such as the Shield Card Shoe developed by UNLV student Brittney Martino in 2015 (US Patent 9,895,599, issued February 6, 2018).^[25] This patented device fits into standard dealer shoes and uses integrated LED lights to project a uniform color overlay or white background onto the backs of cards as they are dealt, obscuring any edge imperfections and rendering sorting ineffective. The invention, born from a gambling innovation class, aims to provide a non-intrusive solution that maintains game integrity while allowing clear visibility for legitimate play once cards are fully revealed. While not yet universally implemented, such tools represent ongoing efforts to adapt to advantage play techniques through engineering rather than procedural changes alone. As of 2025, additional measures include the use of ISO-certified shuffling machines, which enhance randomization of card orientations to further mitigate edge-sorting risks.^[26]
