What Is a Casino?

A casino is a facility where people gamble on games of chance or skill. There are a variety of casino games, and the most common include poker, roulette, blackjack and video slots. Some casinos also offer food and drinks, as well as other entertainment. Casinos have a variety of security measures in place to keep their patrons safe. These measures include cameras, security guards and rules of conduct for players.

Something about gambling (and perhaps the presence of large sums of money) encourages cheating and stealing, so casinos spend a lot of time and effort on security. Casino employees watch over every game, looking for blatant cheating such as palming cards or marking dice. They also make sure the players’ betting patterns don’t signal any type of pattern that could indicate cheating.

Casinos earn their profit by allowing people to play games of chance or skill and taking a small percentage of the wagers, called commissions or rakes. Most casino games have a mathematical expectation of winning or losing, and the house has a large advantage over the players, which is known as the house edge. Some casinos are so profitable that they are able to give away free goods and services to gamblers, known as comps.

Many communities depend on casino tax revenues to fund local services and infrastructure projects. However, it is important to understand that this type of revenue is not a panacea. For example, if a casino taxes $100 million per year for education, total educational spending will still be below what it would have been without the casino.
