Casino Facebook Aplication

I want an aplication on facebook where the users can play many games of casino like blackjack, roulette, etc. but they can play the casino with points, NO money; so for example i add the aplication then i get 10000 points for welcome; with this points i can make bets and win more points; so the total points must be saved on facebook and the user can change or buy stuff in my site with the points that they earned in the aplication. My site is made with joomla using jomsocial and in this site the facebook users aplication should change their points for articles
