Some people live on a Fantasy Island, don't they!
The only way a Dealer can "hit" a single number deliberately, is to stop the wheel, and physically place the ball in that pocket!!!
HOWEVER, He/She could repeatedly "hit" a number or sector in what appears to be a predetermined decision, and have that misinterpreted as so-called "skilled-target-shooting", and the "proof" then passes into the archives of folklore as fact!
The MYTH is further qualified, when the Dealer announces or otherwise signifies, (prior or post spin) that the result was/is predictable and the result of his/her ball/wheel control.
In truth, if the Dealer (a priori), announced the predicted result, then actually "hit" the exact number he forecast, it is still a random coincidence, that is as much of a surprize to the Dealer, as it is to anyone else present at the event.
I have personally seen this EXACT situation occur many times during the last Fifty or more years, and have often used a qualification response to burst the developing "incredibility" bubble, "Bravo, Amazing, -Could you do that AGAIN?-(but let us get our wagers in place first)
What a predicament our Croupier is in, because he knows, the Inspector knows, the Pit Boss knows, and I know, that the chances of him repeating his random prediction result is exactly the same as prior to the previous result, 36 to 1, minus the 2.7 percent for a single number result. -R.
