We received the following question:

When receiving free money for slot play are the odds for using that money the same as real money. Example: I receive $25 for free slot play and insert it in a machine for play would the odds for winning be the same as if I used real $25 money. I never win with their money and needed to ask the question and if there is no difference would there be a law against doing it.

And here is our answer:
The machines do not differentiate between free play and real money.

They are both treated the same.
