The term casino is most often associated with a place where gambling games are played. It has also been used to refer to places that add a host of other luxuries, such as restaurants, free drinks and stage shows. But there have also been less lavish places that house gambling activities and could still be called casinos.
A casino makes money by charging bettors for the opportunity to win a jackpot, either through random chance or with some skill. Many casinos employ a number of security measures to discourage cheating and stealing (by patrons or by staff). Security cameras are an essential component of any casino.
Most casino games have built-in statistical advantages for the house. The house edge may be small, but it can generate huge sums of money over time. It is this revenue that has enabled casinos to build elaborate hotels, fountains, pyramids and towers.
Something about the presence of large amounts of money encourages people to attempt to cheat and steal, whether independently or in collusion with crooked employees. This is why casinos spend a large amount of time, effort and money on security.
Online casinos have to take care of transaction costs, so they usually instate several T&Cs that make it difficult for players to simply deposit a bonus and walk away with the money. For example, some casinos require that you wager your bonus a certain number of times over before you can withdraw it. This is known as the rollover, or playthrough requirement.
