The casinos must have the criteria that they used to determine the payment processors that they are going to take. It is very obvious that some of them will receive MasterCard and some other forms of payment gateways like the Paypal etc. There must be a reason why they would accept the payment system that they chose. Most of the casinos do not have the same payment processors, they decide to choose the one that suits them.
