How Casinos Make Money

There are many ways for casinos to make money, but the biggest is through gambling. Slot machines, black jack, roulette, craps and keno are the major games that casinos use to generate billions of dollars in profits each year.

Poker is another big part of a casino’s business, and most US commercial casinos will have a few tables. The world-famous World Series of Poker is held out of Las Vegas, and most casinos will have live poker tournaments and televised events.

How Casinos Stay Safe

Security at a casino is a complex and multi-layered system, which includes cameras and rules of conduct that all players are expected to follow. But there are also a few more subtle aspects that can help security workers keep an eye on the action at a casino.

The Math Behind Casinos

Without the mathematical edge that makes casino games profitable, casinos would not exist. This advantage, called a house advantage, is created through the way that a casino combines different factors to determine how much it will win.
