Casino is an indoor amusement park for adults, and its games of chance make it possible for the owners to reap billions in profits each year. Floor shows, lighted fountains and shopping centers lure visitors, but the real money comes from games of chance like blackjack, craps, roulette, poker, baccarat and slot machines.

A large amount of currency is handled within casinos, making it tempting for patrons and staff to cheat or steal. To combat this, most casinos have a variety of security measures. Video cameras are commonly found, and employees at table games regularly inspect their betting patterns to ensure that no one is cheating. Electronic systems can monitor the exact amounts wagered minute by minute, and statistical deviations are quickly detected.

Besides security, casinos focus on customer service. To encourage gamblers to spend more time and money at their establishments, they offer perks such as free drinks, all-you-can-eat buffets and room rates. Casinos also offer “comps” to those who visit often and play high-stakes games, giving away free hotel rooms, show tickets and even limo service or airline tickets.

Casinos are also considered to be a major source of revenue for some local governments, although critics claim that gambling addicts divert spending from other forms of entertainment and that the cost of treating problem gamblers offsets any economic gains they generate. In addition, many critics argue that casinos are harmful to the environment and contribute to crime.
