Most people who gamble in casinos do so because they believe they have a chance, however small, to win some money. Casinos use this hope to lure patrons in and keep them betting, which earns them a mathematical edge. This advantage can be as low as two percent, but it adds up over time.

Video cameras constantly monitor game play; electronic systems record the amount of each bet placed minute by minute, and detect any statistical deviation from expected results.

Even so, casino security personnel still rely on the familiarity of routines and patterns in casino games to spot suspicious behavior.
