For instance, while some markets like Las Vegas “reimburse” you for each spin as you take them, other markets, including many on the East Coast, let you load a bucket of free play into the machine at first, and you have to bet it once through before it’s cash that can be redeemed.
They can distinguish between cash and free play. Slot machines are able to track a lot of things. I’ve had multiple slot players tell me they believe that slot machine payback is impacted depending on whether you’re using free play or actual cash.
