A variety of games can be played in a casino. Many of these games are considered table games and are characterized by an element of chance. Some of the most popular table games include roulette, blackjack and poker. A croupier or dealer deals the cards in these games. Other popular casino games are video poker and bingo.

Casinos are usually staffed with security personnel who patrol the floors and respond to calls for assistance or reports of suspicious activity. They also have specialized departments that monitor the casino’s closed-circuit television system for signs of criminal activity.

Some casinos also employ mathematically-trained people called gaming mathematicians to determine the house edge of different games and to develop strategies that maximize their profits. These professionals are also known as gaming analysts.

Many people who play online casino games do so on a regular basis, and they also gamble at real-world casinos.
