A casino is an establishment for certain types of gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shops, cruise ships and other tourist attractions. In addition to slot machines and table games, some casinos feature live entertainment.

Gambling in all its forms has been a part of human culture for millennia. The earliest recorded games were played with dice, around 2300 BC in China. Later, in the 1400s, the game of baccarat emerged, followed by blackjack in the early 1600s. In modern times, casino gambling has become very popular. It is legal in most states and is an important source of income for the governments of some nations.

In the United States, casinos are generally licensed by state gaming control boards to operate various types of gambling activities. These include card games, dice, slot machines, racetracks, and more. Some casinos are also known for hosting live entertainment, such as concerts and stand-up comedy acts. The prestigious Caesars Palace in Las Vegas, for example, is famous for its live entertainment venues, having hosted the likes of Frank Sinatra and more recently, Celine Dion.

In general, casinos try to limit the amount of money that patrons can lose. To this end, they use a variety of security measures. For example, many casinos have cameras located throughout the building to monitor activities. In addition, some have catwalks that allow security personnel to look directly down on players at the tables and slot machines through one-way glass.
