A casino is a place where gambling activities are carried out. It offers a variety of games of chance for players to gamble and it may be combined with restaurants, hotels and other entertainment venues.

The modern casino is more like an indoor amusement park for adults than a traditional gambling den, with musical shows, lighted fountains and shopping centers helping to draw in the crowds. But the vast majority of the profits (and losses for the owners) still come from gambling. Slot machines, blackjack, roulette and other games of chance generate the billions of dollars in annual revenues that casinos rake in.

Something about gambling attracts people who want to cheat, steal or scam their way into a winning jackpot. As a result, casinos spend a large amount of money and effort on security. Modern casino security is typically divided between a physical security force and a specialized surveillance department. The physical security force patrols the casino and responds to calls for assistance or reports of suspicious or definite criminal activity. The specialized surveillance department operates the casino’s closed circuit television system, commonly known as the eye in the sky.

Although gambling has been around since primitive times, when dice made of cut knuckle bones or carved six-sided ones were used, the idea of a dedicated venue for the practice didn’t develop until the 16th century. At that time, a gambling craze was sweeping Europe, and wealthy Europeans would gather in places called ridotti to play cards and other casino games.
