Edge sorting is a technique used in gambling to gain an advantage over the house. Players use specialized cards with asymmetrical edges to identify specific cards in the deck. This allows them to predict which cards will be drawn next and adjust their bets accordingly. Synonyms for edge sorting include card marking, card reading, and sorting shuffles. Some players also refer to it as "advantage play" or "advantage gambling." While edge sorting can be a highly effective strategy, it is also considered cheating and is illegal in many casinos around the world. Any player caught engaging in edge sorting could face severe penalties, including fines and jail time.
