The casino bonus is now so ubiquitous among online gambling sites, that it’s truly the rare online casino that doesn’t offer at least some type of casino bonus.  And with the ever-expanding number of online casinos has come a corresponding increase in competition — something that is always a good thing for the consumer.

In the online gambling industry the increased competition has not only resulted in more online casinos offering bonuses but it has also resulted in increased competition between online casinos to offer the best casino bonus.  Not every casino bonus is the same, however, and it is incumbent upon all online gamblers to learn what’s out there and which one is best for them. 

While most players know about the match-deposit bonuses and no-deposit bonuses and even the sign-up bonuses that some online casinos offer, fewer know about the refer-a-friend casino bonus.  Unfortunately, this casino bonus is not offered at all online casinos so you may have to search around a bit before you find an online casino that does offer one, but it just might be worth your while to do so.  Many online casinos are offering anywhere from $25 to $100 just for referring a friend to their site.  For that amount of money these casinos definitely seem worth the time required to do a little investigating.
