That was my thought too, when I read the question. But it appears that (I've only seen this game in Bond movies...)
- each game is independent; the outcome of the previous game does not change the next game in any way.
- each of the N outcomes in a game is equally likely.
- there are a bunch of bets that select multiple outcomes and payoff factors
There is nothing interesting here...
Unless you believe there is a way for the dealer to affect the outcome, which seems to be what the question is about. I'm pretty sure it would be possible to build a robotic dealer that could target half of the wheel with some degree >50% of accuracy. If I was a bored, minimum wage dealer, I'd almost certainly be trying to see if I could somehow do that. Then the question becomes "can I tell after 40 games (the first 20 minutes of a 30 minute run for a dealer) how to place a bet for the last 10 minutes?" because some of the multiple outcome bets do target sectors of the wheel.
The little bit of research I just did was kind of crazy. The site I wanted to reference had a section on monopole magnets, so I'll leave that out. I'm going to clear my cookies now.
