You're missing the point. With 10 roulette wheels spinning 24/7 2 times per minute on average you get 1.7 million spins per day. There's a 1 in 54,000 chance that any three spins will be the same as the previous spin. Therefore, 4 in a row is a routine occurence. It happens every day. The pit boss won't even notice it, much less think his wheel's broken. Of course, a wheel could be broken, but 4-in-a-row is no indication of this. A normal wheel will get 4-in-a-row frequently. It is simply not that rare or remarkable.

And it's still orders of magnitude rarer than your moon example!
