Typically, a casino is a large building where people can play games of chance. The establishment is often accompanied by restaurants, retail shops, and live entertainment. It is also sometimes a location for conferences, conventions, and corporate events.

Casinos are a highly profitable business, but the odds are in the house’s favor. That is why most casinos are equipped with security measures. These security measures are usually divided into a physical security force and a specialized surveillance department. The physical force responds to calls for assistance and the specialized department monitors casino games.

The specialized surveillance department is commonly known as the “eye in the sky,” and its staff works closely with the casino’s assets to ensure the safety of guests. The department uses a closed circuit television system to monitor casino games.

Casinos typically offer incentives to “good” players, including free drinks and cigarettes. Some casinos also offer reduced-fare transportation for “big bettors.” These incentives may be given as a reward for playing a specific number of hands, completing a certain number of rounds, or winning a certain number of games.

Some casinos offer a “chip tracking” system, which means that the casino monitors the exact amounts wagered minute by minute. This method enables casinos to minimize the casino’s house edge.

The “chip tracking” method also allows casinos to monitor all of their winnings. Casinos have a mathematical expectation of winning, and they use the on-board computer chips to calculate that expectation.
