I shouldn't do this, but I'll give y'all my secret formula for winning at roulette. I made it up, but other people probably made it up before me. It goes as follows:
- Put your money on black for every play.
- Start with a $2 bet.
- Every time you lose, double your previous bet.
- Every time you win, revert back to a $2 bet.
The net effect of this process is that every time you win you'll have $2 more than the last time you won. Since the odds of winning are slightly less than 50%, you'll average about $1 in winnings per play. (Check the math, it works!)
The flaw in the "system" is that you'll eventually encounter a long string of loses in a row. The amount that you have to bet during these strings goes up exponentially, and it quickly exceeds the amount of money that normal people are willing to risk. Even if you have tons of money, the table will have a maximum bet that is allowed.
