I think it will be very good to give something more to the players that they give money for the game.for example is good to take with 80 tokens and 5 green,5 red,5 blue or a ball with gifts inside or a gift anyway,or some game money,or something but not only tokens!depending on the circumstance of the money that the player give!
Also in the same *tab* again some times i wish send to my friends some facebook credits for tokens OR some tokens instantly,this will be very good to!
