A casino is an establishment for gambling. These buildings often combine with hotels, resorts, restaurants, retail shopping, cruise ships or other tourist attractions. The term may also refer to a place that has been licensed and regulated by a state government or national gaming authority. These casinos are required to adhere to certain rules and regulations to ensure that players are treated fairly and the games are kept in check.

Modern casinos have become more like indoor amusement parks than the traditional gambling houses. They feature lighted fountains, elaborate themes, high-end shops and even Michelin-starred restaurants. Yet, the vast majority of their profits still come from games of chance. Slot machines, roulette, blackjack, baccarat and other table games all contribute to the billions of dollars in annual revenues that casinos generate.

The modern casino is usually divided into a physical security force and a specialized department that oversees the closed-circuit television system, known in the industry as “the eye in the sky.” Both departments work together to identify suspicious behavior and prevent crime inside the establishment.

Casinos frequently offer free goods and services to “good” players, such as hotel rooms, meals, show tickets and limo service. They are designed to make the patron feel like a special guest and to keep them coming back for more. This is also known as comping.
