A casino, also known as a gaming house or gambling house, is an establishment for the conduct of various types of gambling. Typically, casinos offer table games, slot machines, and poker rooms in addition to hotel rooms and restaurants. They may be standalone or integrated into hotels, resorts, or other tourist attractions. In some countries, casinos are licensed and regulated by the government.

While some casinos are open to all ages, many are designed for adults. Research by Roper Reports GfK and TNS shows that the typical American casino gambler is a forty-six year old female from a household with above average income. These people are more likely to be single or married without children and have the most available vacation time and spending money.

In addition to focusing on noise, light and excitement, casinos attempt to persuade people to gamble by offering free food, drinks and other perks. The most lucrative inducements are given to high rollers. These people receive discounted or free show tickets and meals in the hotel, free transportation and rental cars, and other benefits.

Security is another major component of a casino. The employees on the floor keep their eyes peeled for blatant cheating or other suspicious behavior. Other personnel, such as pit bosses and table managers, watch over the tables with a broader perspective, looking for betting patterns that might indicate cheating. Elaborate surveillance systems give the casino an eye-in-the-sky view of all activities on the floor.
