No, I'm willing to bet it's about as random as flipping a coin.  You might say, huh?!  I think my theory is interesting but this isn't really a maple question although perhaps we can make it into one, it would be that much more interesting.  I haven't done so yet, but anyone is welcome to.

With practice, I can flip a coin and get 30 heads in a row no problems.  Now say for a roulette wheel operator who uses it constantly, you don't think he's gained some skill in using it don't you?  Of course he has.  Maybe not with razor number accuracy but I'm sure he can skew the results quite readily.  How? 

These are the number sequences for the roulette wheel (just for interest)

Single-zero wheel
0-32-15-19-4-21-2-25-17-34-6-27-13-36-11-30-8-23-10-5-24-16-33-1-20-14-31-9-22-18-29-7-28-12-35-3-26
Double-zero wheel
0-28-9-26-30-11-7-20-32-17-5-22-34-15-3-24-36-13-1-00-27-10-25-29-12-8-19-31-18-6-21-33-16-4-23-35-14-2

First divide the wheel in half, then it becomes like flipping a coin.  I'm sure the roulette operator could easily place the ball in one half or the other, even you and I (with some practice) could probably do the same.  As he becomes more skilled and talented I'm sure he could place the ball within a certain quarter or even 1/8th of the wheel.  Why would he do this?  Obviously because making the odds even more house favorable they can make more profit.

Now, he would quickly scan the bets and see which region the ball should land to give the least payout.  I almost wonder if you could use the same idea to increase your own odds of winning ie place your bet close to a section of the wheel where the number of bets are minimum?
