This depends from casino to casino. Some casino's have got some kind agreement to accept (or pola slot gacor exchange) other casino's chips. These casino's work together in order to maximize a person his gambling and casino experience. There is however not much information to be found on this on casino's websites. So the best thing to do, is ask in a casino if they are willing to accept these chips. The chances of them accepting them are going to be very small.
