A casino is an establishment for certain types of gambling. It is also known as a gaming house or a gambling den. Casinos are most often built near or combined with hotels, restaurants, retail shopping and other tourist attractions. Some states have special laws regulating the operation of casinos.

Many casinos have security measures to prevent cheating and stealing by both patrons and staff. These may include video surveillance systems, armed security guards and rules that require players to keep their chips visible at all times. Something about the large amounts of money handled by roulette online a casino encourages people to try to cheat or steal, either in collusion with other patrons or independently; this is why casinos spend so much time and effort on security.

In addition to the obvious games of chance, many casinos offer poker, blackjack and other card games. These games are sometimes played against the house, where the casino takes a percentage of each pot (or charges an hourly fee). The other way to play is at “ring” or “live” tables, where patrons face each other.

The largest casinos are found in Las Vegas, Nevada; Atlantic City, New Jersey; and Chicago, Illinois. There are also a number of Indian casinos, which are not subject to state antigambling statutes. Some casinos are owned by major hotel and resort chains; others are independent. The MGM Grand in Las Vegas, for example, includes a large casino as well as a world-class restaurant, retail shops and a three-ring rotating stage for live entertainment.
