Edge Sorting in Online Casinos

Edge-Sorting in Casinos: Strategies, Risks, and Effectiveness

  • 23rd, Jun 2023

Edge-sorting in casinos is a method employed by some casino players to gain an advantage in certain games, such as online casino baccarat games and blackjack. It involves recognizing minor differences in the patterns and designs on the backs of playing cards and using that information to make more informed decisions about which cards have been dealt and which are still in the deck. 

Edge-Sorting in Casinos

By examining the minute details on the back of the cards, players can gain a better understanding of what cards remain in the deck, enabling them to make better decisions and increase their chances of winning. Edge-sorting is a technique that some players employ to exploit these details and gain an advantage in certain card games. 

Edge-Sorting History

The world may never have heard of the technique known as “edge-sorting in casinos” had it not been for the famous edge-sorting cases in casinos involving the highly successful gambler Phil Ivey and his accomplice Cheung Yin “Kelly” Sun. In 2012, they won an incredible total of $22 million from Croakfords Casino and Borgata Casino.

To ensure their success, they made several unusual requests to the casinos. They asked for certain cards to be rotated at 180 degrees for religious reasons, that a specific deck be used throughout their games, and that a Mandarin Chinese speaker be allotted to them.

Additionally, they insisted that only an automatic shuffler be used to deal the cards, as their intention was to engage in edge-sorting in casinos. What Ivey and Sun were actually practicing was the technique of edge sorting, wherein they requested a Mandarin-speaking dealer to ensure that their instructions remained confidential and not easily comprehensible to others present in the casino.

Sun had studied the decks at many different casinos and therefore knew which ones had flaws. They rotated the cards so Ivey could read the irregularities and identify high-value cards. Finally, they asked for an automatic shuffler because it makes edge sorting far easier. 

Identifying Small Variations in Playing Card Patterns

Edge-sorting in casinos are employed in the card game that a casino provides, where players keenly observe and identify subtle distinctions in the pattern or design on the back of playing cards. These strategies encompass how to edge-sort by recognizing minute variations in the patterns alignment, the spacing between elements, or even the color scheme employed.

By employing edge-sorting techniques, which involve observing minute discrepancies on the edges of playing cards, the player is able to keep track of which cards have been dealt and which are still left in the deck. 

This meticulous attention to detail grants the player a distinct advantage in the game. So, how to identify edge-sorting in casinos? Look for players who exhibit exceptional focus on the cards’ edges, constantly examining and manipulating them. 

However, it’s important to note the edge-sorting risks involved. Casinos have implemented strict policies against edge sorting, considering it a form of cheating. If caught, players can face severe consequences, including being banned from the casino, legal actions, and reputational damage.

Gaining an Edge in Card Games

By studying the subtle differences between the backs of the playing cards, the player can gain a better understanding of what cards are likely to be dealt in the next round, increasing the edge-sorting effectiveness. 

This knowledge of edge-sorting in casinos can then be used to make more informed decisions when playing games such as baccarat and online blackjack real money, potentially improving the player’s chances of winning.

However, it’s worth considering the edge-sorting future. As casinos become more aware of edge sorting and implement countermeasures, the effectiveness of this technique may diminish over time. 

Casinos have been actively working to enhance their security measures, update card designs, and train their staff to detect and prevent edge sorting. It remains to be seen how the ongoing evolution of technology and countermeasures will impact the viability of edge sorting as a successful strategy in the future.

For example, the player may be able to determine when it is more advantageous to hit, stand, double down, or split depending on the cards that are most likely to be dealt. Edge-sorting in casinos can thus give the player an edge over the casino, allowing them to make more profitable decisions.
