Average prices this year for High Roller Casino are down according to pinpedia to an average price of $1450, Boston pinball says 1800, Pinside says average of 1300 so the average of all those is about $1500.
As far as gameplay I really had fun playing this pin. It sure does not look very pretty but I like the layout. Pretty open playfield a few fun toys. The ball is stopped a decent amount of time so not so much a flow game but as I said I had fun playing it. All in all pretty fun to play so if you can get it at a decent price its worth looking into. Have you ever played it before?
