I know you can bet on every spot on the table and win. All through bet manipulation.
I prefer the even bets particularly red/black. If you know the probability of a certain number in a row and you have a system that can beat it you can win. I am not suggesting to anybody to double up on anything. Was merely pointing out that it was a successful system, and these systems revolutionised the game by bringing the maximum bet to where it is today. What it did was say, yes we can be beaten, and when we do we will simply change the rules...
Instead of doubling up and when you have 1 win you are in front, why not increase a little slower and cash in on a few of yours in a row...

All this is presuming you have a truly random situation. A dodgy spinner unless on a packed table or a mate of yours would not be a situation I would 'gamble' on.....
