A casino is a public place where players can engage in a variety of games of chance. Although gambling is the primary activity, a typical casino adds a number of other luxuries to attract players. These include stage shows, free drinks, and restaurants. Some casinos also offer free gaming, free food, and other perks.

Casino chips have different colors, each one representing a different value. Red chips, for instance, stand for $5, green chips for $25, and black chips, for $100. These value varies regionally and nationally. Therefore, different casinos may use different colors for different types of chips. Casinos usually brand chips to avoid players from buying fake chips.

Casinos typically have two types of security, a physical security force and a specialized surveillance department. The former patrols the casino floor and responds to requests for assistance from patrons, while the latter runs the casino’s closed-circuit television system, also known as the casino’s “eye in the sky.” These two departments work together to prevent crime and ensure guest safety.

Casinos spend a lot of money on security. They employ mathematicians and computer programmers who study casino game statistics. These professionals oversee the fairness of the games. Their work enables them to determine how much money they will make from players.
