I know the machines were the demise of many of the casinos from talking to slot people at them. A few were just to far out of the way for enough tourists to walk through. The Luxor from what I have observed had the highest number of people playing for them AND keeping them of any casino out there. That was likely due to the beautiful designs on their strikes. They had more play on average than even the Four Queens has had. Bad part was I could win 5 strikes and the slor people have to come over after each play and mess with the hopper. I bet they are back once the new machines come into play assuming they work well.
