A casino is a facility where people can exchange money for chips and play games of chance or skill. They also offer entertainment shows. To gamble at a casino, you must be of legal age and follow the rules and regulations. You can play table games like blackjack and roulette, or slot machines. A casino is often a destination for tourists and business travelers.

Casinos make money by charging a fee for each bet placed. This can be as low as two percent, but over millions of bets it adds up to significant gross profits for the casino. In addition to the vig, casinos earn money by providing services like free drinks and cigarettes while gambling, luxury hotel rooms, reduced-fare transportation and lavish entertainment.

Because large amounts of money are handled within a casino, both patrons and staff may be tempted to cheat or steal, either in collusion or independently. This is why casinos spend a lot of time and money on security measures. Cameras are located throughout the facility, and some have catwalks in the ceiling that allow surveillance personnel to look down through one-way glass directly on the tables and slot machines.

In many countries, casinos are licensed and regulated by the government. However, the presence of a casino in a community is controversial, because studies show that it shifts spending away from other forms of local entertainment and increases crime rates. Additionally, the cost of treating problem gamblers and lost productivity from gambling addicts can erode any financial gains for the casino.
