What is a Casino?


A casino is a place where gamblers risk their money on games of chance, such as slot machines and table games. Most casinos have a built in advantage over the players, called the house edge. This advantage can be a small percentage, but it adds up over the millions of bets placed by casino patrons each year. Casinos make their money from the house edge, or vig, and from the fees charged on some games, such as poker.

There are many famous casinos in the world, including the Bellagio in Las Vegas, which has featured in countless movies and TV shows. Other popular casino destinations include Monte Carlo in Monaco, the City of Dreams in Macau and the Casino de Lisboa in Portugal. Casinos are also popular tourist attractions, with visitors flocking to their glamorous entertainment offerings and luxurious accommodation options.

Because of the large amounts of cash handled within a casino, both patrons and staff may be tempted to cheat or steal, either in collusion with each other or independently. To prevent this, casinos have extensive security measures. These may include a high-tech eye-in-the-sky system that watches every table, window and doorway, or cameras in the ceiling that can be adjusted to focus on suspicious patrons.

Some casinos have their own security teams, but others outsource this work to independent companies that specialize in gaming analysis. This involves calculating the house edge for each game, and determining the variance (how much of an expected profit or loss a casino will experience). The mathematicians and computer programmers who do this work are known as gaming mathematicians or analysts.
