Was there last month and my slot jammed so the slot worker came over and opened up the machine with her key. She had trouble getting the machine back on line and had to re-boot the system. It displayed a PC DOS like script on the screen, which I wasn't supposed to see, and it had all the stats and data about that machine scrolling by. I distinctly saw the payout % that the machine was set to. 84.6%... I thought most slots were usually set to 90-95%. If I play long enough to bet $1k I will lose $160 on average. However, I do believe the high roller area has more loose slot %'s based on my experience.
