A casino is an establishment for certain types of gambling. Often casinos combine a gaming floor with hotel rooms, restaurants, retail shops and other entertainment venues. The term casino may also refer to an entire city or region. The word is derived from the Latin cazino, which means “to try” or “to wager.” Gambling has long been an integral part of human culture and history. The precise origins of gambling are unclear, but it is believed to have evolved in many different societies throughout the world and into modern times.

Casinos make money by offering games of chance, such as slots, poker and roulette. Each game has a built in advantage for the house, which can be less than two percent of the total amount wagered on a particular game. This edge earns the casino enough to cover overhead and pay employees, while still leaving a substantial profit for the player.

Because of this built in advantage, it is very rare for a casino to lose money on any one game or day. This virtual assurance of gross profit allows casinos to offer big bettors extravagant inducements like free spectacular entertainment and transportation, luxury living quarters and reduced-fare food and drinks while gambling.

Because of the large amounts of currency handled within a casino, security is a major concern. Patrons and staff may be tempted to cheat or steal, either in collusion or independently; casinos have strict security measures to prevent these activities.
