Riches of Zeus Casino Game

This one is much better than all the rest I have played. But, when you get down to the meat of the game, its just like all the rest. They want you to buy credits, and that is the one thing I refuse to do. As long as I can play for free, I will, but not for money, Ive worked to hard for mine. Its a lose, lose situation!
Also, what are the "gems" good for? Can you use them?
