A casino is a gambling establishment that provides a variety of games where chances are a factor in winning or losing. It also offers dining, drinks and other luxuries to encourage people to gamble. A few casinos also have stage shows and dramatic scenery to make the atmosphere more exciting. There have been many types of gambling houses throughout history, but they all have similar characteristics.
Most of the games that people play in a casino involve some chance and others require skill. Regardless of the game, most have a built in house advantage that ensures that the casino will win over time. This advantage can be expressed mathematically by the concept of expected value, or more simply, as the house edge. The casino gets its money by charging a commission, known as the rake, on each bet. Casinos also give out free goods and services to players, a practice known as comping.
There are many games that can be played in a casino, but the most common are poker, blackjack and slot machines. Other popular games include baccarat, craps and roulette. Some casinos specialize in one or more of these games, but most offer a wide variety of options.
Something about the atmosphere of a casino and the presence of large sums of money attracts people to cheat, steal or scam their way into a jackpot. That’s why casinos spend a great deal of time, effort and money on security. Casino security is usually divided between a physical security force and a specialized surveillance department. The physical security officers patrol the casino and respond to calls for assistance or reports of definite crime. The surveillance staff monitors video cameras and oversees the games themselves. They look for betting patterns that might indicate a player is cheating.
