Right. Bellagio has a bank of quarter (or 50 cent?) progressive VP machines.
Royal Flush of course is progressive, but also, the 4OKs and SF, etc.
All the progressives require a hand pay, which is really annoying for the small wins, to have your machine lock up and have to sit there and wait.
On the positive side, they are usually pretty quick to come and pay, since no paperwork is involved.
