In order to become a member of the Slot Club you MUST earn 500+ points. Because the "new member" cards are not assigned to people, you can find them all over the casino. Check the number of points on the cards, If your lucky, you will find one with over 100 points on it. I don't know how much coin in it takes but I'm sure it's over $3000 - $5000 coin in to get your name on a card!
