A casino is a place where people gamble with cash or chips on various possible random outcomes or combinations of outcomes. Casinos use cameras and other technological measures to enforce security, and they also employ rules of conduct and behavior to promote responsible gambling.

Some casinos offer free drinks and snacks to their guests, while others require players to pay for those amenities. Some casinos are operated by government agencies and are subject to strict regulation. Other casinos are privately owned and operate independently.

There are three general categories of casino games: gaming machines, table games, and random number games. Gaming machines, such as slot machines, allow a single player to play at a time and do not involve the involvement of casino employees. Table games, such as blackjack or poker, involve one or more players who compete against the house and are conducted by casino employees known as croupiers or dealers. Random number games, such as roulette or craps, generate random numbers from a computerized system.

The Monte Carlo Casino, a famous landmark in the city of Monaco, is often associated with James Bond novels and films. It has been the setting for many fictional adventures of spies, dispossessed royals, and wartime adventurers. It has also served as the backdrop for a variety of music events, including the 1958 and 1959 Eurovision Song Contests. It is a popular destination for both locals and tourists.
