You'll hear this all the time on forums. The group of "You can't win against roulette" misfits will spout this over and over, it's everywhere. "Does it win flat betting ?" If it doesn't - then your method/system/idea has NO merit whatsoever. This is what they preach to us/you and they love to bring this up. When I see someone say it in a post I have to laugh, clearly they have little-to-no knowledge of math, random or roulette to say such nonsense - yet it's one of their favorite lines to combat someone's worthy idea. So let's just lay this one to rest - and don't worry, there will be posts after this one telling me how I'm wrong and lack knowledge - but it's up to the reader to know who is pulling BS over their eyes and who's telling them the truth. It's up to the reader and their common sense (always prevails). The same crew of people have infested every forum for literally YEARS and they always spout the same bad information, from the Fallacy that doesn't exist - to Law of Thirds (or whatever name you want to call it) being something that doesn't exist - to "Flat betting" being the only way to prove something working or not. All of these are nonsense and those who know better understand this - but the new people have no idea. Enjoy reading the responses below this post. Why does the house typically win ? The house edge. A guy betting $1.00 per spin or a high roller betting $200.00 per spin or higher are faced with the EXACT same house edge. One might win $10.00 and the other might lose $20,000 - they never at any time faced a different "enemy" at the table, it's always the same. To prove this nonsense about flat betting - here's a good example. It's a way that no one on earth would play, but it has to be shown this way to prove the math and make the point. Nothing is different between these two players..neither is using ANY bet selection or system/method whatsoever - they are just sitting there riding out the 37 spins. Player A) flat bets $1 every number, every spin for 37 spins. After 37 spins his balance is -$37.00 Here's the house edge based on his bets.. House edge clearly 2.70% Player B) starts with $1.00 every number, and increases using a progression +$1.00 on every number, every spin for 37 spins. He's not flat betting, he's using a progression. After 37 spins his balance is -$703.00 Here's the house edge based on his bets.. House edge clearly 2.70% Both players lost different amounts, of course. Both players did NOTHING to change the house edge because they used the same identical strategy. Flat Bet vs Progression = the SAME. It's HOW you bet, where you bet and why - which makes this 2.70 change. Player A) doing his "thing", Player B) doing his "thing" either flat betting or progression will each either end up or down. The "progression" does nothing to change the house edge. *They'll agree to this and try to post how "nothing can work then" because the house edge never changes - yet it does. It's silly to argue this but they will. A slot machine for example that pays off 98% is a good example. Players can play all day and lose, another player can win the jackpot. The house "expects" it's edge to be 2% over time with all players combined. In roulette it "expects" it's edge to be 2.7% over time with all players combined. They never (at the end of the day) go "Oh look, 2.7% !" in their profits. One day it could be much more than this, other days much less. But regardless - saying proof of something working ONLY if you show it via flat betting and not using a progression is nonsense. They are both the same. They want to compare apples and apples and pretend there is a difference. If your bet selection is good and produces a profit - it will work flat betting and will work better (in $ profit) using a progression. If it's bad and produces a loss - a progression will mean a much higher $ loss in the end due to the increase in betting amounts. On a side note - tomorrow I'm going to be at (a) casino. I expect my edge to be 20% (not -2.7%). Making such a claim seems absurd to them, but I know ahead of time that I can accomplish a 20% edge in my favor. I'll even flat bet - the edge I end with will be the same exact value whether I flat bet or use a progression - the only thing that would change is the $ profit amount, not the math, not the edge - not one bit. So when you see "If it doesn't win flat betting, it can't win" just remember they are more than likely clueless to the fact that the amount you bet (either flat or progression) won't change the math 1% in either direction.
