A casino is a gambling establishment which offers a wide range of casino games and other entertainment activities. Casinos are also a popular tourist destination, and many of them are located in scenic areas with easy access to major points of interest. For example, Niagara Falls is just a short drive from Caesars Windsor, while the Point Pelee National Park is within reach of visitors staying at the Fallsview Hotel and Casino.

Most casinos are operated by government-licensed and privately owned companies, or by Native American tribes. Licensed casinos are required to adhere to strict regulations regarding their security, fairness, and honesty. Generally, they have cameras in place that monitor all game play and other operations, and players are expected to act with integrity and respect.

Casinos make most of their money from player losses, but they also derive revenue from other sources such as food and beverage sales, slot machines, and tournament fees. In games that involve some skill, such as blackjack or baccarat, players may be able to eliminate the house edge by applying a strategy. Players who achieve this are known as advantage players.

The term casino originally referred to a public hall for music and dancing, but it came to be used in the 19th century to describe a specific collection of gambling rooms. The first famous casino was the Casino de Monte Carlo in Monaco, which opened in 1863 and continues to be a significant source of income for the principality.
