I will play a $10 bill at my machine of choice, no matter what denomination, before moving on.

By the way, yes, I believe the computer chip is random within a slot machine, but, contrary to Casino Player magazine's constant mantra that the machine payouts are set at the machine manufacturer and never changed, I believe that the casino's can change the individual payout on a machine.

One morning, very early (4:00 am), I was on the casino floor (it was very empty) in Atlantic City. In the next aisle was a slot machine tech. I'm tall enough to clearly see over the top of the machines (I mostly stand when I play). The tech had a screen open on a bank of 5 machines. On the screen was a lot of categories and choices--I was clearly able to read them. One of the choices was Payout Percentage. I noticed for the 5 machines, each had different payout percentages, ranging from the high 80%'s to a little over 100% (by the way, the 5 machines were all the Bewitched slots).

Random yes, but set (or re-set) by the Casino, also yes.
