A casino is a building that houses a variety of games of chance and where gambling is the primary activity. A typical casino will add a host of extra luxuries to help attract customers, such as restaurants, free drinks and stage shows. There have also been less lavish places that house gambling activities, and these would still be considered casinos.

Casinos have become a major source of income for many cities, including Las Vegas and Atlantic City, and many nations have legalized them. Despite this, the casino industry has its downsides. For example, there are concerns that casino gambling can lead to gambling addiction and other negative health effects. It is important for people who plan to visit a casino to be aware of these risks and take steps to protect their mental and physical well being.

Some casinos are designed to be tourist attractions in their own right, showcasing architectural design and other aspects of the local culture. The Bellagio in Las Vegas, for instance, is world-famous for its fountain show and luxurious accommodations. Other famous casinos include the Casino de Monte-Carlo in Monaco, and the Casino Lisboa in Lisbon.

There are a number of ways that casinos protect their patrons. Some are staffed with trained security guards, while others have elaborate surveillance systems that provide an eye-in-the-sky view of every table, window and doorway. These systems can be adjusted to focus on suspicious patrons, and they can record videos that can be reviewed later.
