A casino is an establishment for certain types of gambling. Most casinos offer a variety of gaming machines and table games such as poker, blackjack, and roulette. Some casinos also have restaurants, bars, and lounges. Some are located on cruise ships, in hotel towers, and as standalone buildings. The minimum age to enter a casino varies by country and state.

Casinos are often portrayed as seedy backroom gambling parlors, but the majority of them are large, professional facilities that take steps to prevent crime on their premises and off. They hire security guards, monitor their parking lots, and make use of closed-circuit television to observe patrons. They offer a safe environment in which to gamble, eat, enjoy live shows or closed-circuit broadcasts, and generally have a good time.

In casinos where skill determines the outcome of a game, the house edge and variance are carefully calculated by mathematicians who specialize in this field. These calculations are used to maximize the profitability of the casino. Casinos have a legal obligation to report these figures to the authorities.
