A casino is a public place where a variety of games of chance are available and gambling is the primary activity. In addition to gambling, casinos offer restaurants, free drinks and stage shows to attract customers. Some of the most famous casinos in the world are in Las Vegas, but there are many others located around the globe, ranging from lavish resorts to small neighborhood places.

Casinos are also popular tourist destinations, attracting millions of visitors each year. In the United States, some state governments regulate gambling, while others endorse it only for Native American reservations and other restricted areas. Despite state regulations, casinos continue to grow in size and scope. Many feature hotels, spas, restaurants, non-gambling game rooms, bars and even pools.

Security is a major concern for casinos. Due to the large amount of money handled within a casino, employees and patrons may be tempted to cheat or steal. This is why most casinos invest a significant amount of time and money in security measures. These can range from cameras to specialized security personnel.

The casino atmosphere is designed around noise, light and excitement. The walls are often painted with bright colors to create a stimulating environment. In addition, the floors are often carpeted and there is usually music playing. Waiters circulating throughout the casino serve alcoholic and non-alcoholic drinks to customers. There are no clocks on the casino walls, as this is considered a distraction and can cause people to lose track of time.
