I never read casino reviews. I think all these reviews are biased because they are paid. But maybe I'm wrong. And if I want to play in a casino, I just go to the site and try everything I like, I do not need to read the review. I can only give one piece of advice to those who write casino reviews, make them as short as possible. I like short reviews.
Do you want the reviews to be as short as possible or that they should be of honesty without biases 
You know they can still be short and bias.We know that most of these reviews we see online about casinos many are paid reviews which are made to portray a good and reputable name to the respective casino's, nevertheless there are a few among those paid reviews that are made by honest users who based on their experience with the casino poured out their mind as it is without bias which is why I would encourage you to try read reviews about a casino before making use of it for you might extract some atom of truth from one honest review among many bias reviews. Just jumping into a casino site trying everything blindly can be risky as you may not be privy to the real deal not until you had made a deposit there and then some hidden terms would now be revealed.
