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.

A few things.

Many tables have min/max bets which can put a damper on this, but overall you’re betting so much and winning so little the Casino is fine w/ this bet.
