What Is a Casino?

A casino is an establishment for certain types of gambling. Casinos are often combined with hotels, restaurants, retail shops or cruise ships and are known for hosting live entertainment events such as stand-up comedy or concerts.

A thriving industry, casinos bring in billions of dollars every year. While dazzling lights, musical shows and lighted fountains may draw the crowds to casinos, the vast majority of profits come from games of chance. Slot machines, blackjack, roulette, craps and baccarat make up the bulk of casinos’ revenues. While there is an element of skill involved in these games, the house always has a mathematical advantage. This advantage is referred to as the house edge. Casinos also make money through “comps,” or complimentary items, given to gamblers.

Despite their large revenue streams, casinos are not without controversy. Some economists contend that they divert money from other forms of entertainment and hurt local economies. Others argue that the cost of treating problem gamblers offsets any economic gains. Still, some state governments allow casinos in their jurisdictions. Casinos can also be found on American Indian reservations and in other countries that have legalized gambling.
