I actually played it last night, it used to be 150bb max which was very odd for 2/5. They must have changed it to 1k recently which is cool. Also 3+1 rake which I think is the cheapest in town for 2/5.
I think they pay quads or better, then you get to play a hand on a video poker machine and if you draw the same hand you get like 50k, kind of an odd promo.
