What Is a Casino?

A casino is a gambling establishment that offers patrons the opportunity to win money through games of chance. These games may include blackjack, poker, roulette, craps, and slot machines. In addition to offering these games, casinos also provide food and drinks. They are often located near hotels, restaurants, retail shopping, cruise ships, and other tourist attractions.

Casinos make their money by charging a vig, or rake, on each bet placed in the games they offer. This percentage can be anywhere from two percent to ten percent of the total amount wagered by patrons. Some casinos also offer comps, or complimentary items, to their patrons. These items can range from free shows and meals to hotel rooms and even expensive vacations.

Given the large amounts of money handled within a casino, staff and patrons can be tempted to cheat and steal, either in collusion or independently. To counter this, most casinos have extensive surveillance systems. Cameras are mounted throughout the facility and can be controlled by security personnel in a separate room filled with banks of monitors. This “eye-in-the-sky” system can be adjusted to focus on specific suspicious patrons by security workers in the control room. Casinos also have special cameras that monitor each slot machine to see if the payouts are consistent with the odds displayed on the screen.

In order to maximize profit, casinos typically concentrate their investments on high rollers. These gamblers place bets in the tens of thousands of dollars. In return, the casinos offer these big bettors with extravagant comps like free spectacular entertainment and luxury living quarters.
