Reports have come in that one of the four $1 10/7 DB machines at the 4Q has been downgraded/disabled/taken out back and shot. However, the other three remain, for now at least. These are probably the most lucrative remaining machines in Vegas, even with the halved players club benefits. APs have been playing them constantly, especially during promos.
So many have asked the question; why have they only altered one? Why not all four? One person who asked was told it was "a business decision"--an insulting non-answer. I have a pretty good guess, though.
Slot department managers aren't the brightest bulbs in the chandelier. I've noticed in particular that they believe in "lucky" or "unlucky." When pondering the wholesale execution of a group of good VP machines, they often decide to do it one or two at a time. And their criterion is: which machine is losing the most/winning the least? That's the one that gets uprooted/downgraded.
Now, you know how stupid that is: fair machines with identical games and pay tables should return the same percentage to the house over time. But astonishingly, many slot managers still believe there are such things as unlucky machines. I've been told this by slot techs at Stations, Boyd, and most recently Arizona Charlie's, as the inventory of good VP was slowly whittled down. The "unlucky" machines went first.
So the "business decision" machine at the 4Q probably coughed up one too many royals. I'm sure that all the machines know they can be punished for that. So if you're playing the good machines at the 4Q (if any remain), and you hit a royal, whisper gently, "I'm sorry," and kiss the machine. It's the least you can do.
