What Is a Casino?

A casino (also spelled casin or casiono) is an establishment for gambling. Originally, the term denoted an establishment offering table games and slot machines, but in modern usage it is often a facility offering a wide range of gambling activities. Some casinos focus on one or more specific types of gambling, such as poker, blackjack, and roulette. Others offer a mix of games, and some are known for hosting top-billed entertainment shows.

Regardless of the type of game, all casinos are built to make a profit. The odds of each game are mathematically determined, and the house always has a significant advantage over players. To minimize this advantage, casinos employ gaming mathematicians and computer programs to ensure fair play. In addition, many casinos employ staff to supervise the games and provide customer service. Casinos also spend millions on determining what colors, sounds, and scents appeal to gamblers, and they use these factors to attract patrons and keep them gambling.

When most people think of a casino, they envision a megaresort in Las Vegas or another exotic destination blazing with neon lights and excitement. But the reality is that most casinos are small businesses that define themselves more by their gambling activities than by their glitz and glamour. Most of these casinos have two specialized security departments: a physical force that patrols the building and responds to calls for assistance or suspicious activity, and a forensics team that operates the casino’s closed circuit television system, known as the eye in the sky.
