Good questions. They load the free play onto your slots card immediately after you've lost up to $100, unlike some other casinos that can take up to 24 hours later. Secondly, you don't have to play all the free play on the same machine. However, I found that a good number of the slots card readers to be malfunctioning or difficult to operate so I ended up reverting to a machine that had a functioning slots card reader. Also, if I recall correctly in order to activate the free play in addition to first needing to enter your P.I.N., subsequently you'll need to insert some money and play those credits first and then the $100 in free slots play credited into your account will be subtracted accordingly. And lastly, I believe that the free play can be downloaded onto any machine. The more important question that you might want to ask the boothling prior to playing is, "will a progressive slot or video poker machine qualify to earn my free play if I lose $100?" Terrible's may not allow you to play and earn the rebate on a progressive machine, I don't know. Something to think about.
