A casino is a facility where people can play games of chance for real money. A casino may also offer other types of entertainment such as concerts and shows. In the United States, there are many casinos, and they are often located in cities with large populations of tourists.

Some casinos are known for having a high level of security. This is especially important because of the large amounts of cash that are handled within a casino. The security measures may include cameras, employees who monitor activities on the casino floor, and other methods. In addition to these methods, some casinos also hire specialists known as gaming mathematicians or gaming analysts who can help them keep track of the house edge and variance for different games.

In general, the house advantage in a casino game is the percentage of net income that the house expects to generate from the games it offers. This profit is calculated by dividing the total amount of bets made by the number of winning bets. In games that have a skill element, the house advantage can be eliminated by players using optimal strategies. These players are referred to as advantage players.
