I don't know if he specifically has a Blue Samurai video, although it wouldn't surprise me. He does have a lot of videos showing off the different slots, and he's making more almost daily recently it seems like. As someone not familiar with these types of slots, they all look pretty much the same to me. I must say that it is a bit shocking to see someone gamble without six figure buys like it's nothing. He's seems completely disconnected with the amounts of money he's wagering. I saw him win $400,000+ in a recent video yesterday. I couldn't imagine...
I remember reading in WIRED a year ago that those are house money, so for him it's basically nothing. If he loses - he just asks for more. Those vids are there to show what is possible on this or that particular slot, and sometimes I enjoy watching them, but I would never recommend to anyone to risk such big amounts themselves, and, btw, neither Steve is recommending it. "Do not gamble more than you can afford to loose." - this what I just read under one of his slot videos.
