Security is an essential part of running a casino. Not only do employees watch patrons and games, but casinos have elaborate surveillance systems, including cameras that are hidden in ceilings and mounted on windows. The video feeds are recorded and can be reviewed later. Every casino employee is monitored by a higher-up person who has the authority to detect unusual behavior. For example, dealers will shuffle and deal cards, and pit bosses will watch the betting areas and look for patterns of behavior.

Casinos also focus on customer service. They provide perks to entice patrons to spend more money. Often, these perks are free food or drinks. In the 1970s, Las Vegas casinos offered free show tickets and discount travel packages. Those casinos wanted to attract as many people as possible to maximize their revenue. They also offered free drinks and cigarettes to gamblers.

Casinos are also places where the rich and famous go to win big money. The public’s fascination with casinos dates back to the Rat Pack’s film Ocean’s 11. This movie was later followed by sequels starring George Clooney. In fact, millions of dollars flow through the doors of casinos every day. However, this does not mean that casinos are completely safe. Managers must monitor security to protect the public and keep casino patrons happy.

To ensure profitability, casinos use a system called the house edge. The house edge represents the average profit earned by the casino from each game. The longer you play a game, the greater the house edge.
