Online casinos are similar to land-based casinos.  The only major differences is that live casinos offer comps, while online casinos offer players comps in the form of bonuses.  Bonuses are one of the most attractive features of online casinos, because bonuses allow you to play and even win big cash prizes without even using any of your money.
The internet-gaming industry is growing on a daily basis, and there are currently over 1200 online casinos on the net.  This means that online casinos have to compete for customers.  Online casino bonuses are a great way for online casinos to attract new players.  Bonuses include free money, offered to new and potential players, as an incentive to join the online casino.  Online bonuses are a percentage of you initial sign up deposit usually, 50 percent, but, because of the fierce competition, some casinos are offering bonuses as high as 100 and 200 percent.  Each online casino has its own bonus program and its own policies concerning bonuses, so, before you join the casino, be sure to read the rules and terms for that particular site.
Online casinos have individual rules and policies concerning bonuses, but there are rules that all casinos must follow.  For example, bonus money cannot be used when playing certain games, including Blackjack, Roulette, and Craps.  In order to cash out bonus money, a player has to wager their initial deposit and the bonus for a certain number of times, usually between two and five times.
It is good to look around for the best site before joining a casino.  There are many online casinos that offer very good bonuses.  Some of the best online casinos, in terms bonuses, are Platinum Play Casino, Millionaire Casino, Golden Casino, Riverbelle Casino, Rome Casino, Rushmore Casino, etc.
When you are looking for a casino to join, avoid casinos that offer bonuses that are unrealistic, because you will get caught in an online-casino bonus scam.  You will be disappointed to find out that you can’t even claim your bonus.  Most people who have not read the fine print on most of these casinos have found themselves in this predicament.  The best way to choose an online casino to join is not by bonuses, but by the reliability, reputation, customer service, types of games, and other features, such as tournaments, offered at the casino.
