A casino is a facility where gambling is legal and where various games of chance are played. It is also a place where food and beverages are served, as well as entertainment such as shows or live music. A casino can be as large as a full city block or as small as a single card room. The casino industry brings in billions of dollars each year for owners, investors, and Native American tribes. In addition, it provides employment and tax revenues for local governments.

A typical casino offers a wide variety of games of chance and skill, such as blackjack, roulette, and poker. Some casinos specialize in specific games, such as sic bo (which became popular in European and American casinos in the 1990s), fan-tan, or pai gow. Others feature an array of table games, including baccarat and craps. Some casinos even have video poker and slot machines.

The casino business is highly competitive, and it is common for gamblers to be offered free drinks, food, or hotel rooms as inducements to spend more money. Casinos often feature a high-end restaurant and an impressive interior design, which can include exotic architecture or replicas of famous structures.

Although casinos bring in large sums of money, they are not without their critics. Some economists argue that the money spent by casino gamblers could have been used for other forms of local entertainment, and that the cost of treating problem gambling addicts offsets any economic gains from the casino.
