Why can’t people go to the casino playing roulette and bet on black, and if they lose, double what they lost and bet on black again until they win?

If you bet $100, your odds of winning are around 50% and if you lose, bet $200, and so on and so forth until you win, and then cash out with a guaranteed profit. Assuming odds of black are 47.37% as per American roulette, your odds of not winning a single one after 6 tries are 0.02125 (I think) and decrease exponentially after each subsequent try.

I want to emphasize your odds are always less than 50%. It’s possible to get neither red nor black off of roulette due to the presence of the green 0 and 00.

Now if you’re playing a video game that has a Save/Load then there’s usually a way to cheese the system because you have infinite money. But it’s typically faster to bet on a single digit 34 times in a row before reload since a single payout of 35x carries less risk multiple 2x wins in a row. This only works because you can reload if you don’t win. Also the randomness can a bit off and somewhat predictable.
