It’s important to know that the house always has an edge in a casino game. This advantage is known as the “house edge” and is the difference between the true odds of the game and the casino’s payouts. It varies from game to game and is usually expressed as a percentage. A higher house advantage means more money for the casino.
Casinos use computers and video cameras to monitor game activity. They also use a process known as “chip tracking” that enables casinos to monitor the number of bets minute by minute. They also have roulette wheels that are regularly monitored for statistical deviations. Security measures are also used to ensure that patrons and staff do not cheat or steal.
The casino’s house edge is calculated using the house’s mathematical expectation of winning in a particular game. If this were not the case, casinos would be losing money. A casino’s house edge is also called the vig. The house edge is also a commission on certain games. A casino’s pit boss supervises the fairness of the games.
