Some casinos like Tamarack Junction (sister property to Silver Legacy) in Reno allow you to download free play without juicing it with a buck (or higher bill) - you just need to churn/bet the free play in order to withdraw it. Also you can accumulate comp points during the free play rundown there. Others are more stingy and are as you describe. One trick you can use is to find a low value TITO, like a penny, and stick it into the machine. Then you can download the free play without any usage of a federal reserve note.
