It does sometimes feel like this is the case. However I think it just comes down to variance but taken from the entire game roster rather than just individual games. I remember winning huge on 32red only to think that I will never win on there again however this was not the case I still had some wins but also loses. I doubt that casinos have the ability to manipulate the RNG in order to re-coupe payouts. I would just put it down to variance if in doubt just register at a new casino
