A casino, also known as a gambling house or gaming establishment, is a place where people can gamble and play games of chance. Some casinos offer only table games while others feature slot machines, blackjack, poker and other card games. In addition, many casinos offer a variety of entertainment such as comedy shows and concerts. Casinos are usually located in or near hotels, restaurants, tourist attractions and shopping centers. Some states have laws against gambling while others endorse it.

The largest casino in the world is WinStar World Casino, located in Oklahoma. The casino has 60 large plasma TVs and accepts wagers on American football, boxing, martial arts and soccer, among other sports. The casino is also a major draw for its entertainment offerings, with famous names like Frank Sinatra, Liberace and Elton John having played there in the past.

Due to the large amounts of money handled in a casino, patrons and staff may be tempted to cheat or steal. For this reason, most casinos have security measures in place. These can range from cameras to rules of conduct and behavior that prevent theft. In addition, many casinos hire private security companies to patrol the premises.
