Wish I could give it a negative 5 star. Even if you do win a few dollars they claim they can't pay out to Mastercard or visa but claim to pay out by way of same as deposited funds. According to "Les" at worldwinner they only pay to PayPal or by paper check by mail. Now correct me if I'm wrong but ain't PayPal a Mastercard... and NO WHERE does it state this "no visa or Mastercard refunded" BEFORE you deposit money... waste of time... literally worst app ever...
