A casino is a place where gambling activities are carried out. It includes games such as roulette, gaming tables for card and dice, slot machines, and others. These establishments are regulated by government agencies. They are usually located in cities and resorts.

Casinos have been around for many centuries. The exact origin is unknown, but gambling in one form or another has been found in almost every culture throughout history. People like to gamble for money and have fun, but the risks are high. A large amount of money is often involved, and casinos have to invest a lot of time and money in security measures.

In addition to the traditional gambling games, some casinos specialize in exotic games from faraway lands. These include sic bo (which spread to Europe in the 1990s), fan-tan, and pai gow poker. Casinos also invest a lot in technology. Cameras watch patrons, and electronic chips with built-in microcircuitry track their movements. Roulette wheels are electronically monitored to discover any statistical deviations from expected results.

While musical shows, lighted fountains and shopping centers may draw people to casinos, most of the revenue for casinos comes from gambling. Slot machines, blackjack, roulette, craps, baccarat, and video poker all contribute to the billions of dollars in profits that casinos make each year. The downside of gambling is that it can cause addiction. Some studies show that the net value of a casino to a community is negative, due to the cost of treating problem gambling and lost productivity from gambling addicts.
