A Casino is a gambling establishment with a range of games for customers to play. These include poker, roulette, baccarat, blackjack, craps and more.

The word “casino” is a portmanteau of the Italian words kasino and casino, meaning “game house”. In some countries, such as South Africa, a casino can be part of a larger resort or hotel.

Casinos often have security measures in place, including video cameras and employees who are trained to identify suspicious behavior or unusual amounts of money. They are also equipped with chips that interact with computer systems to monitor the exact amount of wagers being placed minute-by-minute; roulette wheels are monitored electronically and players who lose money are warned immediately.

While there is no guarantee that a player will win money at a casino, most of them use fair games based on good math to minimize the short-term risk and maximize the long-term profit. The mathematical advantage of the casino over a player on any given bet is called the house edge, and it is what makes a game gambling.
