You can find 9/5 JOB on $1 machines and up and there are several; one machine was $1 8/6 JOB. I also saw numerous full-pay Bonus Pokers at 99.17% at the $1 level.
As for finding out information about getting a point per coin-in, or other necessary inputs to get to the cash back rate -- it's was a fool's errand.
I did stay around for their "party pit" and I hate to say it but it sucked. I remember when Harrah's in Reno had these hot looking dealers dress up in eye-catching swimming outfits or corsets and it was done with style. That was Harrahs in Reno, this is Shingle Springs, CA, enough said.
