Bet 5 on black, if lose bet 10, if lose bet 20, if lose bet 40, when win go back to origional 5 bet and repeat.... in theory for 30 spins an hour you should win 50% of time, so 15 x $5 is $75 hourly rate.... aslong as your rolled to cove a big loss streak you will always make $5 on a win and break even on a loss because you make second bet bigger!!!.will casino ban you from doing this??? What else can effect this???

the flaw is table limits

I was going to type something sarcastic but instead I will take the higher road and give you a real answer.
Tables are generally $5-$1000 (or $500 in a lot of cases)
I have seen 1 color cover an entire electronic board which I believe is 20 numbers. I have also seen this more than a handful of times and I do not play all that often. If you start at $5, your 9th bet would be $1280. Ok so even if you are "lucky" enough to have 2 people sharing a plan your 10th bet is $2560 so you are already over the limit. What if you find a $5-$5000 table? you 11th bet is over the limit already. When this happens you will be completely screwed. You could probably go tonight and make money doing this, you could probably go every day for the next week and make money but as soon as you hit that one huge downswing you just lost all of your profits for a week and probably plus some.

In another thread I did my own "system" which of course was debunked by everyone on here. I ended up playing enough to get the top tier level at my casino and I stopped. I ran well and made a little money but I obtained my goal. If you have a realistic type goal it is worth a shot but if you think that you can make a boat load of money then move on to your next idea.

Not really.

Google geometric progression

The flaw is in thinking previous winning numbers have any bearing on future winning numbers.

It's not even really that usually. There are people who do this in sports betting as well. Bet 10 bucks on a game, if they lose pick another game with a bigger bet, if they lose that pick another game with a bigger bet, etc. The flaw is playing a losing game. Table limits, wheels not having a memory, and the like don't have much if anything to do with it. I mean to go back to the table limit thing brought up a couple of times in this thread do people really think that's what breaks these system players? Of course it isn't. It's that they run out of money. Casinos will risk $5 to break a million dollar martingaler...it's not the table limits.

ETA - and regarding the flaw being wheels not having a memory...again, I really don't think that's much of what the martingaler thinks. If he does he's really stupid because he shouldn't martingale he should just watch the wheel and bet against/for streaks after the fact. The heart of the martingale alure is the progession thing and this idea that they can just "get up when they're ahead" and somehow magically be winners by getting in their car and taking a drive before playing their next hand. Really silly but again doesn't have much to do with table limits or wheels/cards not having memories.
