I can’t particularly point out only Referback, but can honestly say that ALL microgaming casinos for me produce no results, yet Playtech and RTG give me brilliant results across the board.
I don’t know whether it is a case of many gamblers already having accounts at the older microgaming casinos, but then why aren’t they playing? because I am not even seeing any existing players playing let alone new players.
In the past I have always pushed microgaming casinos and still do, in the hope that I will eventually get players…but when it comes to the top positions on my sites – they don’t go to microgaming casinos anymore – they go to playtech!
