The word casino, which means “gambling house” in Italian, refers to a place where people can play a variety of games of chance for money or other prizes. Modern casinos are often combined with hotels, restaurants, shopping centers, and entertainment venues. They offer a wide range of gambling options, including slots, poker, blackjack, roulette, craps, and baccarat.

Casinos are designed to appeal to the senses of sight, sound, touch, and smell. Bright lights, flashing symbols, and the clang of coins hitting the slot machines draw people in. Patrons are encouraged to shout encouragement, and alcoholic drinks are readily available from waiters circulating the casino. Casinos employ a variety of security measures, because they handle large amounts of cash and patrons may be tempted to cheat or steal, either in collusion with each other or independently. Cameras throughout the facility and a separate room filled with banks of monitors enable surveillance personnel to watch every table, window, and doorway.

Although lighted fountains, musical shows, and elaborate hotel themes help draw people in, casinos would not exist without the games of chance that provide the billions in profits they rake in each year. Each game of chance has a built in advantage for the casino, which is known as the vig or rake, and this edge can add up over time. The vig is the primary source of revenue for casinos, and it gives them the funds to build impressive hotels, casinos, and theme parks.
