A casino is a place where people can play games of chance. There are a variety of games available at casinos, and the odds on each one are calculated mathematically. Often, the house has an advantage over the players, but this varies depending on the player and the game.

The most common casino games are poker and roulette. Most casinos offer multiple versions of each. In the United States, for example, there are Texas Hold’em, Omaha, and other types of poker. There are also video poker machines.

In addition to the games offered, there are many other attractions. Most casinos have restaurants and hotels, as well as shopping malls. A number of artists perform there.

Security is a major concern in a casino. A specialized surveillance department operates the closed-circuit television system. It works closely with the casino’s assets to ensure that patrons are safe. They also have a physical security force that monitors the casino.

Casinos have security cameras in the ceiling and in each doorway. They keep a watchful eye on every table. They also record video feeds that can be reviewed later.

Typically, a specialized surveillance department, known as the “eye in the sky,” works with the casino’s security staff to prevent crime. They work primarily to protect the casino’s assets. This includes monitoring the betting patterns of the tables, as well as detecting suspicious behavior by patrons.

There are also cameras that monitor the wheels of the roulette tables, as well as the betting spots on the table. This allows the casino to spot blatant cheating.
