A casino is a gambling establishment where players can gamble money on games of chance. The most common type of casino is a hotel-casino, although there are also tribal casinos and online casino sites.

Poker is a popular game in many casinos. Nearly all commercial casinos and tribal casinos in the United States offer poker events and regular poker games.

Slot machines and (from the 1980s) video poker machines are the economic mainstay of most American casinos, with high volume, rapid play at sums ranging from five cents to a dollar generating a significant income. Other forms of casino gambling include baccarat, chemin de fer and blackjack.


Security is a major concern at casinos, particularly for children and minors. In addition to cameras and other technology, casinos enforce rules of conduct and behavior. Often, this involves the use of microcircuit betting chips to monitor player behavior and make adjustments as necessary.

In some cases, the use of these devices makes it difficult for a player to cheat and steal from other players. The casinos are able to track the movements of the player and their reactions to each other, and these details help security personnel to spot suspicious behaviors.


Some casinos offer free perks and benefits to their “good” players. These are typically offered in the form of discounted travel, hotel rooms, meals and tickets to special shows. While comps are often given to people who place large bets or spend large amounts of time playing slots, they can also be offered to lesser spenders.
