Whether it’s hitting the slots, laying it all down on the roulette wheel or throwing a dice at a craps table, casinos are where people go to satisfy their gambling cravings. And while a trip to the casino doesn’t have to break the bank, there are certain things to keep in mind.

First and foremost, know that casino security is a big deal. A lot of thought and money goes into making sure the gambling floor is safe for all. This includes a high-tech eye-in-the-sky surveillance system that keeps tabs on every table, window and doorway. Cameras can be angled to zoom in on suspicious activity, or adjusted to focus on a particular person. Casinos also use bright and sometimes gaudy floor and wall coverings to create a stimulating, cheering effect. Red is a popular color because it’s believed to make people lose track of time. And you won’t find any clocks on casino walls.

While most gambling games are based on chance, some have an element of skill, such as blackjack and video poker. The casinos still make their money through the mathematical advantage they have over patrons, known as house edge or expected value. In games such as baccarat and trente et quarante where players play against each other, the house takes a fee or rake to cover its expenses.

The average patron may not have an expectation of winning much, but a few lucky gamblers can make a fortune. As a result, casinos regularly offer comps to good players, which can include free hotel rooms and dinners, limo service or even airline tickets.
