Stations does the “reimbursement” freeplay thing, where after you play, it reimburses you the amount you played. If you just cash out, you’ll end up with however much cash you had in the machine.

The only place I can think of off the top of my head where you can just cash out freeplay is places like Dotty’s or gambler’s bonus. I don’t think they’re even considered to be freeplay.
