A casino is a place where gambling activities are carried out. Casinos may have elaborate stage shows, restaurants and dramatic scenery to attract visitors but in the end they are about gambling. In fact casinos make their money by ensuring that all bets placed on their games have a built in statistical advantage for the house. Even the small bets of many gamblers add up to a huge amount of gross profit for a casino.

Casinos have become a big business and they provide jobs and tax revenues for many state and local governments as well as the corporations, investors and Native American tribes who own them. But the casinos would not exist without games of chance like slot machines, blackjack, roulette, poker and craps which provide the billions in profits raked in each year.

Unlike other gambling establishments such as lotteries or Internet gambling, casinos are social places where people interact with each other and often shout encouragement to their fellow players. Many casinos are decorated with bright and sometimes gaudy colors such as red which are thought to stimulate the senses and increase excitement. In addition the noise level in a casino is usually quite high and waiters circulating through the gaming area offer alcoholic beverages to casino patrons.

People are attracted to gambling because it gives them the opportunity to win lots of money in a relatively short period of time. It is not surprising that a significant percentage of casino visitors are addicted to gambling. Gambling addiction has been linked to a number of psychological problems including depression, alcoholism and drug abuse.
