A casino, also known as a gambling house, is an establishment that allows people to gamble. Casinos are most often found in hotels, resorts, cruise ships, and other tourist attractions, but they can also be standalone. Some casinos specialize in specific types of gambling, such as card games or keno. A casino may also offer additional services such as restaurants, bars, and entertainment.

Most casino games have a built-in long-term advantage for the casino, known as the house edge or vigorish. Players whose skills can overcome this disadvantage are known as advantage players. Casinos use sophisticated statistical analysis to determine the house edge and variance for each game offered. This is done by skilled mathematicians and computer programmers known as gaming analysts.

Many cities around the world are famous for their casino scene. These include Las Vegas, which attracts millions of tourists every year. This is largely due to the fact that it offers a wide variety of things to do and see.

In modern casinos, security is usually split between a physical security force and a specialized department that runs the casino’s closed circuit television system. The physical security force patrols the casino and responds to calls for assistance or reports of definite criminal activity. The specialized department monitors the casino’s video surveillance system, which is commonly called “the eye in the sky.” In addition to this technology, some casinos have catwalks above the casino floor that allow security personnel to look down on tables and slot machines through one way glass.
