Platinum players reward card

I do gamble once in a while whenever and I find Ceasars Entertainment a great place to chill out and hang out in their restaurants. I have a platinum players reward card where I get to win rewards whenever I play. This is unlike other gambling sites where there is no reward for choosing them as a preferred betting site. I am trying to see the kind of reward I can get with this service. If they are a scam I will come and let you know. As a responsible gambler, I have won several times though not large amounts of cash and they have been prompt in paying. So far, nothing negative to say about them, but will do it in case I see something fishy.
