A casino is a gambling establishment that features table games (like blackjack, poker, roulette and craps), as well as slot machines. To gamble at a casino, you must be of legal age and follow the rules and regulations set by the casino. Some casinos also offer entertainment shows.

Something about gambling encourages people to cheat, steal and scam their way into a jackpot, which is why casinos spend a large amount of time, effort and money on security. Casinos use surveillance systems with cameras that watch every table, window and doorway. They also have catwalks in the ceiling, allowing surveillance personnel to look down on patrons through one-way glass. They can even adjust the cameras to focus on certain suspicious patrons.

Casinos make money by charging a percentage of each bet placed on their games. This is called the house edge, and it can be a very small percentage, but over millions of bets it adds up. This is how casinos can afford to build elaborate hotels, fountains, pyramids, towers and replicas of famous landmarks.
