Almost every casino has some form of security measures in place to protect its patrons. Typically, these are divided into a physical security force that patrols the casino and responds to calls for assistance, and a specialized surveillance department that watches the entire casino.

Casinos use a wide variety of tricks to attract gamblers, including free drinks and stage shows. Guests also receive a set amount of chips to use while playing.

High rollers pay more for gambling than the average casino visitor. Casinos earn much of their profits from these gamblers. These high rollers are also awarded complimentary items, luxury suites, and lavish personal attention.

In 2005, the average casino gambler was a 46-year-old woman from a household with an above-average income. Nearly half of Americans had some college credits.

The National Profile Study, conducted by Roper Reports GfK NOP, interviewed more than 2,000 adults in the United States. About 24% of Americans visited a casino in the past year.

Casinos usually make their money from a combination of taxes and fees, and gambling. In some states, casino-type game machines are permitted in truck stops and other small businesses.

Most casinos also have security cameras, a closed circuit television system, and elaborate wall coverings. Some casinos even have catwalks that allow surveillance personnel to look down into the casino. Those cameras can be adjusted to focus on suspicious patrons.

Gambling in casinos encourages cheating and stealing. It also shifts spending from other forms of local entertainment. In addition, gambling addiction can harm people.
