Not freeplay, but one of the casinos I go to has a drawing almost every time I go there. Never heard my name for years, so really didn't pay much attention to the announcements. Sure enough, one day they called my name and said to meet at a specific location. My friend was playing right next to me and I just shouted, "that's ME!" and ran, leaving my players card and cash in the machine. Had to run back and get my players card and then I got to pick a key from a basket and scan it to find out how much I had won. It was $200 cash. I was thrilled!
