He's talking about the Martingle system. (At least I'm pretty sure.)

This is a fine system, if you have unlimited funds, with unlimited wagering ability. If you hit a streak of 11 misses in a row, which isn't too crazy to think of happening, then ... frankly, you're [censored].

And many casinos have limits on bets.

So, basically, your system has you double your bet each time until you win, then you're up one initial bet. Let's use your system ($200 bet with a $20,000 bankroll (100x$200)

Assume you lose each roll (for the sake of 'bad luck'):
Bet 1: $200 Total down: $200
Bet 2: $400 Total down: $600
Bet 3: $800 Total down: $1400
Bet 4: $1600 Total down: $3000
Bet 5: $3200 Total down: $6200
Bet 6: $6400 Total down: $13000
Bet 7: $12800 Total down: $25800

You can only spin the wheel 6 times until you don't have enough money for the next bet to bring you back up to even.

6 rolls ... could it really land on one color that many times in a row? Well ... why not?

Edit: millions --> unlimited
