The risk of getting caught card counting in blackjack involves attracting suspicion from the casino due to unusual betting patterns, especially when bets increase during favorable counts. Casinos monitor players closely with surveillance, and if they suspect card counting, they may ask the player to leave or ban them from the property. In response to suspected counters, casinos might also alter game conditions, such as reshuffling more frequently or increasing the number of decks. While card counting is not illegal, casinos have the right to refuse service, and players caught counting may face uncomfortable pressure or restrictions.
