Some factors carry more importance than others, so they have a more significant effect on our rankings. This is particularly relevant when ranking for specific categories. For example, when ranking the best online casinos for bonuses and rewards, we obviously place a lot of importance on the sign up bonuses available and how much value there is in the loyalty schemes.
Indeed, not only do many of them have a greater plethora of casino games to choose from that’s far greater than the selection of games available at land-based casinos in comparison, but online gambling sites also have casino bonuses galore, online casino promotions in the dozens and even rewards programs that come across as far more lucrative than those on offer at their land-based counterparts.

In a virtual casino game, the outcome of each game is dependent on the data produced by a pseudorandom number generator (PRNG). This determines the order of the cards in card games, the outcome of a dice throw, or the results produced by the spinning of a slot machine or roulette wheel. PRNGs use a set of mathematical instructions known as an algorithm to generate a long stream of numbers that give the impression of true randomness. While this is not the same as true random number generation (computers are incapable of this without an external input source), it provides results that satisfy all but the most stringent requirements for true randomness.

Our expanded Top 10 Casinos list has been one of the most visited pages on our site since we started in 2003. OCBB tests each of the online casino sites listed by actively playing at these casinos and always using feedback from other players. That data is collected and analyzed and based on the figures tallied, and finally, the casino is assigned a rank based on their payout percentage, overall customer service, the number of games and software. Another important factor is the size of the bonus offered by the casino. When notified of any positives or negatives of a casino that we had not previously taken into consideration, we re-evaluate the casino in question. There are links to read in-depth reviews of each casino, as well as links directly to the casino site.

There’s still a perception by some politicians and gamblers alike that the internet gambling industry operates in a “Wild West” environment where there are no rules, restrictions or regulations. In reality, virtual casinos are quickly accepting oversight similar to their land-based counterparts. All reputable sites are regulated in at least one established jurisdiction that serves to provide oversight and consumer protection for players.


We understand that the world of American online gambling sites can be a confusing one. New US online casino gamblers might not know what to look out for. Our team of reviewers has decades of experience between them and very stringent standards. We know what makes the best Internet gambling sites good. We also know what the warning signs are and we use this to scrutinize casinos during our vetting process and only recommend the best.
