A casino is a gambling establishment where patrons can gamble. Some casinos also have restaurants, hotels and/or retail shops. Casinos can be located in cities, towns and rural areas. Casinos can also be found on cruise ships, riverboats and at Native American reservations.

Although a casino can provide other forms of entertainment, the vast majority of the profits are generated by games of chance such as blackjack, roulette and slot machines. Musical shows, lighted fountains and lavish hotels add to the glitz of the casinos, but they would not exist without the billions in profits from gambling.

The casino business is a dangerous one, and it is not uncommon for cheating and theft to occur. To combat this, casinos have many security measures in place. Typical security measures include cameras that watch every table, window and doorway. These can be monitored by security workers in a room filled with banks of security monitors. In addition, windows and clocks are rarely seen in casinos, as they allow patrons to lose track of time and spend much more money than intended.

The history of the modern casino began with organized crime and mafia money. Mobster bankrolls helped casinos draw crowds to Reno and Las Vegas during the 1950s, but their deep pockets were not enough to overcome gambling’s seamy reputation. Real estate investors and hotel chains had more money than the mobsters, and they were able to buy out the mob’s stake in casinos. This, combined with federal crackdowns on mob involvement in gambling, forced the mobsters to find new ways to make money.
