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.

How had no one said the answer yet? Have you people never been to a casino?

The reason you can’t martingale is because tables have maximum and minimum bets. Lets say it’s a $5 minimum table. The maximum would be $500.
So your martingale goes 5,10,20,40,80,160,320…. Then you can’t double it again.

7 in a row streaks are not as uncommon as you might think. Also in this case you’ve risked $645 to win $5. It’s really not a good play.

Also the people mentioning gamblers fallacy are incorrect here. Each spin is independent but the chance of consecutive occurrences is to be treated as one outcome with a probability 1/2^n
