Card Counting Detection
Countermeasures
The methods and procedures used by surveillance and floor personnel to identify players who are counting cards in blackjack or other card games to gain a mathematical advantage. Detection indicators include bet spreading (large increases in wager size when the count is favorable), playing deviations from basic strategy, team signaling, and concentration patterns. Surveillance monitors player behavior through camera observation and may use specialized software to analyze betting patterns for count correlation.
In practice
Card counting is not illegal under federal law or in most jurisdictions, but casinos may exclude known or suspected card counters; some jurisdictions have specific regulatory frameworks for handling advantage players.
