Casino is a place where gambling games are played. Casinos often offer other attractions to their patrons, such as restaurants and stage shows. Some casinos are known for their glamorous reputation, such as the Bellagio in Las Vegas, and others are famous for their unique architecture or historical significance.

Most people who visit casinos are there to gamble. The atmosphere is designed to encourage people to gamble by providing noise, light and excitement. Many casinos use bright and sometimes gaudy floor and wall coverings that stimulate and cheer the players on, while others provide alcohol and nonalcoholic drinks to their patrons free of charge to encourage them to gamble more. There are also usually no clocks on the walls of a casino because the idea is that people will lose track of time and continue gambling until they run out of money or until their luck changes.

Casinos are also often places where people meet friends and socialize. This social aspect of the casino makes it different from other types of gambling, which are largely solitary activities. Casinos may offer various perks to attract customers, such as discounted or free tickets to events and meals, drink vouchers, and hotel room discounts. This marketing approach is referred to as loyalty marketing. It is effective because consumers are more likely to trust other people than they are to trust a brand. Moreover, loyalty programs are less expensive than other forms of advertising.
