You have to amass 100 "daily" points to be eligible for one. I went to the casino - didn't have my card - played slots and won a few jackpots. Then got a card but of course had no daily points on it because the casino did not "know" of my fun victories. So no mask for me. They are black and have the Soboba wooden log/feather logo on them. Maybe at some future visit when I am carded jackpotted and the supply holds out . . . I can get one.
