The casino business model is a highly profitable one. The house edge is a mathematical formula that ensures the casino has an advantage over the players. The casino edge is sometimes referred to as a “rake”.
The casino’s business model is based on a system of rewards. “Comps” are given to customers who play games of skill. They are based on their level of play, length of time spent in the casino, and stakes placed on their games.
Casinos have security measures to prevent the theft of money or other property from customers. These measures include cameras and surveillance. They also use video feeds to monitor games. Security cameras can also be adjusted to focus on suspicious patrons.
