The need for bonus
Gambling Operations often need and have to use incentives to lure customers to play on their sites. In the case of traditional casinos in hotels and gambling dens the incentive is usually in the form of complimentary dinners and drinks or other similar forms of enticements. Obviously, as far as an online gaming site is concerned, this scenario is highly unlikely. The only way to lure customers in this case is through cold, hard cash.
Casinos, like any other business will need to spend money on publicity and advertising. For online poker sites, the best sales promotion will be to give away bonuses to their players. This will not only earn them a good reputation attracting more customers, but will also help in building goodwill.
It is true that these bonuses are not going to make you rich, but they add to your bank balance and are beneficial if you decide to play on a wide variety of sites.
However, the casinos make sure that you just don't take your bonus and leave. You are required to play a certain amount of raked hands, before you can avail the benefit of the bonus. Although it varies from site to site, typically, this amount is ten times the bonus that you get.
