A casino uses elaborate surveillance systems to monitor the gambling floor and its patrons. Cameras in the ceiling monitor every table, doorway, and window and can be adjusted to focus on suspicious patrons. The video feeds are recorded and later reviewed. Casino security is so high that there are no live employees watching the slot floors. Instead, a higher-up employee keeps tabs on each of them. Despite the extensive surveillance system, people are not exempt from cheating or getting involved in illegal activities.
Most casino games are based on chance or skill. In general, the house has the edge in games of chance and skill. In most cases, the odds are mathematically determined, meaning that the house always has the advantage. This advantage is called the house edge or rake. Additionally, a casino may offer its customers complimentary items and comps, in addition to winnings. The casino’s payout percentage is the percentage of winnings returned to the players.
A casino’s statistical edge is a factor in how much a patron wins. The house has an edge over the player if the casino pays out more than they can afford to lose. Casinos spend millions of dollars on security, and the odds of winning are overwhelmingly in their favor. But the house advantage is not so high. In fact, casinos are often able to afford these expenses. So the casino will offer free drinks and cigarettes to lure the best customers.
