The task of attracting and retaining customers on the site is important for any commercial project. Especially it is relevant to the virtual casino, because on the Internet almost every day there are new portals offering everyone a huge selection of slot machines (and not only them). Quality design and rich content these days no one can be surprised - go for a variety of bonus programs, which have a very solid history.

At the dawn of virtual casinos

Initially, the bonus program institutions were only affiliate relationship. Roughly speaking - you were charged a certain "plus" for what you attracted to the site of other users. But gradually marketers began to realize the flaw of this approach, and programs of this type began to be more global in nature. Through trial and error, three main areas of bonus programs were identified, which can now be found in any virtual best Australian online casino.

These days

So, the three pillars of the bonus program are:

• Increased winnings for a certain period of time (about a few weeks);
• A given number of free spins for a certain set of slot machines of the virtual casino;
• increasing the amount paid by the user to the deposit (sometimes up to 100%).

It is clear that the first two methods can be implemented only with a certain amount of luck, but the last one you can get a bonus here. Probability theory makes it clear that the game with the slot machine is essentially a series of independent tests. And the "black bar" can easily pursue you during the whole period of the bonus program. But the extra money in the account will not be superfluous - especially if this direction of the bonus program is relevant for the first few operations with the personal account of the user. There is nothing surprising that it is the latter type of bonus program that is most widespread.
