A casino is a facility that offers various forms of gambling, including slot machines, gaming tables and other games. Casinos are located in a wide range of places, but the best known are those in Las Vegas and Atlantic City. In addition to offering gambling opportunities, many casinos also provide entertainment and dining venues.

In a casino, money is handled in large amounts and the risk of theft is therefore present. For this reason, most casinos employ security measures to deter theft by either patrons or staff. These include physical security forces, as well as specialized surveillance departments that operate closed circuit television systems. In addition, most casinos have a number of security cameras throughout the premises, some of which are hidden.

A few places have become almost synonymous with a casino, the most famous being Monte Carlo, in Monaco, but there are casinos in other parts of the world as well. In the United States, a growing number of casinos are being built in states where they were previously prohibited. The proliferation of casinos is partly due to changes in state laws and partly due to the rise of Native American-run casinos. The casino industry has also benefited from the popularity of online gambling, which has led to an increase in online bonuses for players. These bonuses can add up to significant sums, making online casinos a very competitive option for gamblers.
