Casino is an establishment offering various types of gambling. In most cases casinos are combined with hotels, restaurants and other entertainment attractions. While the word casino may conjure up images of Las Vegas and other flashy cities, there are many more casinos scattered around the globe. Some are located in exotic locations like Venice and Monaco. Others feature top-notch hotels and amenities like spas and dining options. The casino industry generates billions of dollars each year for its owners, investors and Native American tribes. The games played at these casinos can be both thrilling and relaxing.

The majority of casino revenue is generated by slot machines. Other popular casino games include blackjack, poker, baccarat and craps. Gambling in some form or another has been a part of human culture for millennia. Evidence of dice games dates back to 2300 BC, and card playing became widespread by the 1400s. In the United States, gambling was legalized in Atlantic City in 1978, and it grew rapidly from there. Casinos also appeared on various American Indian reservations, which were exempt from state antigambling laws.

In addition to stimulating atmospheres, casinos use a number of other tactics to encourage patrons to spend more than they plan to. They frequently offer free items or reduced-fare transportation, hotel rooms and dining. These are known as comps.

Because the amount of money that changes hands in a casino can be enormous, security measures are essential. Cameras are placed throughout the facility and staff members are trained to spot suspicious activity. In addition, many casinos have catwalks that allow surveillance personnel to look directly down on the action on the tables and slots through one-way glass.
