Thanks Mandogone and thanks Bluecat.
I am a little confused on where you get the "combinging free chips and real money" part... Please let me know if I missed something.

There would obviously be limits, such as max cashouts, etc... but I think the appeal that you have the opportunity to win (even if a limited amount) without being labeled a "bonus abuser" and worrying about getting winnings would bring a lot of players in and keep them playing.

I would assume with the system (whether there be a cap on the amount of free chips between deposits or not) would work for both the player.
With the increased playthrough it would become harder to reach and thus cashout, but you would still have the chance. And for a small deposit you would be able to set the playthrough back to the minimum for your next free chip....

Keep the ideas coming! Not sure if this could ever go anywhere but I like the idea anyways!
