A casino is a place that houses games of chance and gambling activities. It can offer a variety of other luxuries to its patrons, including restaurants, free drinks and stage shows. It also often features dramatic scenery and luxurious accommodations. However, there have been less elaborate places that house gambling activities and still be considered casinos.

Various tactics are used to draw in gamblers, such as bright lights and loud noises. Many casinos use the color red to stimulate the senses and encourage people to gamble. They also do not display clocks, as it is thought that keeping track of time will distract gamblers from gambling. Elaborate security systems monitor the casino floor and can be viewed in a separate room filled with banks of security screens.

Something about gambling seems to encourage people to cheat, steal and scam their way into winnings, which explains why casinos spend so much time, effort and money on security. Every game offered by a casino has a mathematical expectancy of winning, so casinos make sure that their games are played within the expected parameters. For large bettors, casinos often offer extravagant inducements such as free spectacular entertainment, chauffeured transportation and elegant living quarters.

Despite their immense profits, casinos are not without critics. Studies show that the net economic benefits of a casino are often negative, as it diverts money from other forms of local entertainment and can contribute to gambling addiction. There are also concerns that the tax revenues generated by casinos do not always benefit the community as hoped.
