The online play offered by a new type of casinos generated some controversy about the advantages of both. While many remain controversial, it is clear that online casinos were able to successfully prevail in a very short time, collecting old traditions of any physical casino while transforming many of its old patterns.

The physical casinos are bounded and limited to specific areas. The mobile casinos are banned by most national legislations. Their schedules of activities (different for each country and often for different types of casinos) are also bounded. These two elements are a real limit to the number and people can stay in a given time within that space. On the other hand, necessarily involves the transfer of the player instead of game. Online casinos are open 24 hours a day, 7 days a week throughout the year. There are no fixed boundaries in virtual space, so there may be thousands of people playing at the same time and from anywhere in the world where a computer and a connection to the Web.

Operating costs for a physical casino are usually high (large number of personnel, high costs for heating or air conditioning, electricity, maintenance and building improvements, maintenance of furniture, fixtures and equipment, etc.).. Much of those costs disappear in the casinos operating online, and have been cleverly used to offer more services to its customers in bonuses, additional points of the game, all kinds of promotions and prizes for the player changes the possibilities of juices, rise in the betting structure, more and better customer services, the use of different languages, technologies increasingly safer, more variety and choices of games, the creation and adoption of clear rules to ensure fair play.

All these improvements and attracted more customers, generating other demands were quickly met by the online casinos, including the power suit players of varying levels (whether economic or game) with more options for play and bet level. And the wheel continues to turn up today, but it appears that the upward trend in online casinos can be reversed.
