A casino is a facility that offers various forms of gambling, including slot machines and table games like poker, blackjack and roulette. It also often includes restaurants and entertainment shows. To gamble at a casino, you must be of legal age and follow the rules and regulations set by the establishment. Casinos are typically regulated by government agencies and offer players a variety of security measures.

Beneath the varnish of flashing lights and free drinks, casinos stand on a bedrock of mathematics engineered to slowly bleed patrons of their cash. For years mathematically inclined minds have tried to turn the tables by using their understanding of probability and game theory to exploit flaws in a rigged system. But despite the many strategies published in books and online, the truth is that luck, not skill, determines most of the outcome of a casino game.

There are dozens of casinos in the United States, each offering their own unique mix of table games and slots. Some are as big as a small city, while others are tucked away in remote corners of the country. The most famous casino in the world is probably Las Vegas, but there are plenty more to choose from.
