A casino is a place where a variety of gambling games can be played. It may include table games like blackjack and roulette, as well as video poker and slot machines. Some casinos offer other forms of entertainment such as shows and fine dining. It is not uncommon for a casino to have an enormous stage that hosts big name entertainment.

Modern casino security is usually divided into a physical security force and a specialized surveillance department. The physical security force patrols the casino, responding to calls for assistance and reports of suspicious or definite criminal activity. The surveillance department operates the casino’s closed circuit television system, known as the eye in the sky. The eye in the sky allows casino security personnel to watch every table, doorway, window and change room at a moment’s notice. Casinos use this technology to monitor their patrons’ actions, and it is often used to detect cheating and other crimes.

Most casino games have built-in advantages that give the house a mathematical expectation of winning. This is why casinos must spend a large amount of time and money on security. They also rely on rules of conduct and behavior to protect themselves from people who try to cheat or steal. These measures are important because something about gambling seems to encourage irrational behavior in some people, making them want to scam or rig the game instead of simply placing their bets and hoping for the best.
