Sun International review: payout

Hi

My name is Robin

I have played at Grandwest Casino and became a MVG cardholder i stayed away in the beginning and recently went back i have since gone from the Maroon Card to the Silver Card and from my Silver Card i have gone to a Gold Card

so far everytime i visit i play at least a R1000 or more and i have never won a Jackpot or a big amount

take for example i was cashing out one evening and i witnessed how a Platinum Card Holder Won R40000+ twice in a row on a slot machine in it put me off because that meant in order to win an amount that big i would have to play to get to platinum which take very long and then only start winning big

Are the Cards Fixed to lose?
