A casino (also spelled as
Some casinos are open to the general public; others are private clubs or member-only establishments. The games offered in a casino are usually controlled by one or more dealers and may include traditional table games such as blackjack and poker, as well as video slots and other electronic devices. Casinos are often operated by private companies and are subject to government regulations.
In modern times, casinos have increased the use of technology for both security and supervision of the games themselves. For example, chips with microcircuitry allow casinos to oversee the exact amounts wagered minute-by-minute and warn players of any anomaly; roulette wheels are electronically monitored regularly to discover statistical deviations from expected results. In some cases, the games are completely automated and players bet by pushing buttons.
Casinos are a major source of revenue for many governments and are regulated in most countries around the world. However, there are concerns that the large profits from these establishments lead to gambling addiction and can have negative social impacts. Some jurisdictions have prohibited casinos entirely, while others regulate them strictly or limit their size or location.
