It looks like Rollbit has got some huge fans out there, who would like to create a brand just like them, but then they are too lazy to do so from scatch and instead choose shortcuts. Some hours back, Playz.bet was caught pant's down trying to copy the Rollbit layout including the branding/logo and when they were called out, the just deleted the thread and moved it to archival hoping no one ever sees it again 
Well, it isn’t a bad idea to thread the steps of a casino that have been known to work but, when they are you competition, it only paints them to be your better in a lot of ways. The more reason why, the gambling site in question should look for uniqueness of designs and features while employing the services of those that are truly creative.If they get lazy on little things like mascot and logos, what would gamblers be expecting on the casinos interface and game offerings.
