Casino bonuses are one of the most popular methods for the online casinos to attract players. It is a fact that online casinos are able to offer larger bonuses than their land based counterparts, mainly because of their lower overheads. First of all, online casinos do not need any physical property. Apart from that, they need lesser staff and their promotional costs are also lower. 

Because of these reasons, online casinos are able to offer free money, tournament tickets and merchandise to the players in the form of casino bonuses. Their sole aim is that once the players have started playing at their casino, they should stay there.
