A casino is a gambling establishment that provides tables for card games and dice, slot machines and other gambling equipment. A casino also hires employees to supervise the game play. The establishment is regulated by state laws and may be operated by individuals or businesses.

The modern casino is like an indoor amusement park for adults, with the vast majority of the entertainment (and profits for the owners) coming from gambling. Slot machines, black jack, roulette, craps, keno and poker help make up the billions of dollars in profits that casinos rake in every year. Musical shows, lighted fountains and shopping centers help draw in the customers, but casinos would not exist without these games of chance.

Gambling in a casino is not just about winning or losing; it is also about taking risks and learning to recognize when you are on the edge of a bad bet. The odds in most casino games give the house a built-in advantage over the players. This advantage is known as the house edge.

Security in a casino starts on the floor, where staff members keep an eye out for blatant cheating. Dealers are heavily focused on their game and can quickly spot a crooked card or dice shuffle, while table managers and pit bosses have a much broader view of the table games and can spot betting patterns that could signal cheating. Casinos also use technology to monitor their games. For example, poker chips have built-in microcircuitry that interacts with a computer to oversee the exact amounts wagered minute by minute; and roulette wheels are electronically monitored regularly to discover statistical deviations from expected results.
