Gambling establishments, often incorporating a variety of games of chance and in some cases skill, with a focus on slot machines, blackjack, poker, roulette, craps, baccarat and other table games. These establishments are found worldwide and earn billions of dollars each year for casino owners, investors, governmental bodies, Native American tribes, and the people who play their games. Some casinos are standalone, while others are part of larger resorts, theme parks or cruise ships. Casino-style games are also found at racetracks and racinos, in bars and restaurants, and even at truck stops and other small businesses.

Casinos offer an experience that is unique in comparison to other forms of gambling. Rather than a remote and solitary experience, casino gaming is very social, with players sitting or standing around tables and slot machines, often shouting encouragement to fellow gamblers. There is a high energy and excitement in the air, as well as bright and gaudy floor and wall coverings that are designed to be stimulating and cheering. There are usually no clocks on the walls because it is thought that this will distract gamblers and cause them to lose track of time.

There is a large amount of security at casinos, with cameras watching every table, change window and doorway. Casinos use advanced technology to monitor the games, with systems that allow them to check the amount wagered minute by minute and catch any statistical deviations that might indicate cheating. Casinos are also staffed with “higher-up” security personnel who watch over the employees and monitor the patrons to make sure that everyone is behaving as expected.
