A casino is a place where games of chance are played. While modern casinos include many luxuries to attract customers such as restaurants, free drinks and stage shows, gambling remains the primary activity. While gambling probably predates recorded history, the first places specifically designed to house a variety of games under one roof did not appear until the 16th century, when a gambling craze swept Europe and Italian nobles held private parties at venues known as ridotti.

Casinos generate their profits by charging a percentage of each bet placed to players, known as the rake. The rake is a major reason why some people consider gambling to be a vice and not just a form of entertainment. Casinos also offer free goods and services to high rollers, called comps. These may include meals, rooms, show tickets and even airline tickets and limo service.

Something about the casino environment seems to encourage cheating, stealing and scamming. So casinos invest a lot of money and effort into security. This includes cameras that watch every table, window and doorway and that can be adjusted to focus on suspicious patrons by security workers in a room filled with monitors.

Casinos vary greatly in size, layout and style. Some are designed to be reminiscent of European palaces, while others are themed after Las Vegas or other popular cities. And some, like Macau, are located off the beaten path. Macau is considered the Monte Carlo of Asia and has a distinct Portuguese feel, making it worth visiting even if you don’t plan on gambling.
