Can you provide us on what basis they are ranked or the site used any algorithm script? Whatever it is, I have some concerns about the method you used to determine the rankings as apparently most would not agree to them. For example, I have two favorites here: Fairspin and Betplay Meanwhile Rollbit was not good for me. The withdrawal took too long.
Based on his original post, his ranking and reviews are based on his experience while playing on the website. just like you probably had a bad experience with Rollbit, his bad experience is with Fairspin. as for Betplay, the ranking gap between Rollbit and Betplay is not far.
GamblingBro made those reviews based on his first time experience at every gambling site. And it is normal to face some issues when you play at a gambling site for the first time. A lot of casino process the first withdrawal manually by doing some security check. Most of the casino doesn't offer much bonuses to a new user. If you are a regular gambler at any casino then you will obviously find some differences between your experience and GamblingBro's review. Currently
he use 10 parameters to make his reviews.
