As before noted, I traveled a lot for work and was able to get to vegas every three weeks for a "surgical strike" on them. Well, maybe just reconnaissance on them. One other loan white guy my age had seen me a few times and we asked each other "Do you live here?" He was from Oregon. I told him that I chase 00 at shift change times and Yes, it doesn't always "happen" but I do real well. He started explaining his scheme and i said it was similar to the Martingale scheme - he looks for a history of red on the history board of roughly 16 of the last spins and, when there were more than 3, he would bet 25.00 on black, then 50.00 on black and 2Xprevious until he got a black. He was there that weekend and I, a table stalker of many hours, saw many history boards with all red for the longest sequences. The whole weekend was red and I never...saw...him...there...again. Is the wheel rigged? You can bet it is.
They really watch you there. In 2010 when my 00 chasing really paid off, I was walking around with a handful of nice winnings and the most down-home looking girl you can imagine stood in front of me and would not move in the crowd. Not ostentatious good looks; just the kind to really get comfortable with. Me in my 50s and getting heavier than I should be and being kind of down-home looking myself, she was the perfect match. The fact that they could roust her out of a staging area (free room for her?) and send a perfect match kind of girl my way is scary. Jeans and a peach colored sweater, no rickets / skanky weight loss from drug use, no tats, just a pleasantly solid girl next door. "D - d - do you want a drink." I asked and we talked. This gambling thing really helped me out of drinking too much. I really love it as a hobby. Also, the cost of 2 (4) drinks at their bar is enough to scare anyone away from drinking. She suddenly changed personality and really wanted to play blackjack with my chips. I answered her nay, that I know not much of that game...at least not knowing how to front-run the casino on that game. She really insisted. What would have been her personal interest in me losing at blackjack? She worked for the house....but the way they "read" me and sent a good match for me kind of tells me that this is a world class city of real experts.
My friend had the same kind of Martingale experience in Laughlin. The girl dealer liked him and was eyeing him fixedly and strangely as he kept betting red until the whole 16 position history board was red. She wouldn't (couldn't) say anything out loud but was sort of beaconing with her eyes that he wasn't going to beat the house this way.
Is it the dealer or is it the house that controls the ball? My theory is that it is an independent security firm that gets permission to monitor (control) the wheel allowing plausible deniability to the casino. "Our customers experience a jump in revenue when they hire us, the biggest firm in vegas." they say, and the casinos DO get more from it because the security folks see what is going on, manipulate accordingly, and the secret stays with fewer people. The dealers and casino don't have to know what's going on. "What about the nevada gaming commission?" the trusting citizen asks, and I offer "What about the SEC and the Madoff scandal and regulatory institutions approving known toxic bonds?" With just one major security firm, the secrecy is maintained.
