Look, do what I did. Took my daughter out to eat, no pics, after she got off work. I was playing golf in the area and called her at work to set it up. Met her at her apartment and showered and off we went. It was at the casino so after our dinner we strolled over to the casino. She was only 21 at the time and never ever gambled at a casino. So we strolled around the tables, slots, craps etc., and gave her my limited knowledge of the games. We get to the roulette table and she asks how does this work? I say it's simple, you just put money on a number, color, first, second or third twelves blah, blah, blah. I said you wanna play and she says yea sure. So I throw 40 on the table and get forty chips of a color at dollar each. I tell her she has to bet the minimum at least or bet it all at one time. So she randomly puts chips on different numbers and they roll the ball. She hits. We high five, laugh, enjoy the moment and they pay her 35.00 smackers. She says do we quit now, I said yea if you want but I threw 40.00 win or lose. So she does it again with different numbers. She hits. Woo hoo, high fiving yea we got this. I said that's good, but this doesn't often only betting the minimum. Loses the next spin, wins the next after the losing spin. Cash out a little later, get my forty and she keeps the rest. 50.00 dollars or more. And leave. Now, do understand the probability of that?

i get what you are saying, but what you are missing or scarily overestimating is time.

Sure... over thousands of hours the "probability" of every number being hit somewhat equally is expected.

I watched a guy buy in for about 30k and play six numbers until they hit. He was progressive betting. He lost every dollar. I think he started out with $25 on each number. Good luck!

So your daughter put several dollar bets on the table, one of which was the number that hit right? If you bet on a number and it hits, it pays $35 to every $1.

If you want to "beat" roulette, there is one possible way to do it, but it will require you to have a good bit of money...
You keep it simple. Bet on red or black. First roll you bet $5. You lose. The next bet you bet $10. you lose so then the next roll you bet $20. You hit and you win so you win $20. At that point you will be up $5. So then you lay down $40. If it hits then you win $40 and now have a total of $80.

At that point you can put $25 in your pocket. At that point if you lose all the money on the table you at least break even. So you have $55 to work with. Start off again. $5 bet. If you win, put another $5 in your pocket. Bet the $5 you won, if you lose then bet $10, if you win.. You win $10. Put $10 in your pocket and bet $5... Yall get the point, but you have to be really careful doing this.

No, there are zero possible ways to do it.

What happens when you hit green, Mr. Martingale?

I'm sure someone has mentioned it in this thread, but the probability of losing on 36 straight spins is actually closer to 38%.

I always play black or red.




Black or red pays 2:1 and you had a ~48% chance there. Playing one of the 3 "Columns" pays 3:1. You can easily put yourself in a well hedged position.

Assuming you are playing only one number each spin you have a 2.63% chance of winning each time the wheel is spun. Multiplying by 36 does not give you a 94.7% chance to win your money back. It only means that you have a 2.63% chance of hitting the number each time the wheel is spun and having a 7.3% chance of winning your money back in those 36 spins.

If he hits green he loses, so he just doubles the bet again next spin. He’s right I think, I’m that you could always just double your bet each time you lose and come out $5 ahead once you win. You’d better have a shite ton of money to play this way though haha.

No, you have a 63.7% chance of winning (at least) 1 of 38 times. The math is not fine.


I think you’re approaching this incorrectly. I’m not saying that playing flip a coin means that you have a 100% chance of flipping a heads after 2 flips. What I am saying is that a pay off of 3x of your bet means you’re making 1 dollar a flip on average if you play indefinitely.

ETA: When I said his math is correct I wasn’t referencing the 94%, I was lazy and just kind of glanced over the thinking

The point was that a single green slot makes the chances of winning to get even on any one spin less than 50% if you're playing black/red. That's less than 50% and you're ALREADY in the hole. Every loss makes that hole in your bankroll bigger. Two green slots makes it even worse. You cannot win over time with that strategy, even with a shite ton of money. Eventually, you will hit a string of losing hands that will wipe you out unless you have an infinite bankroll. Casinos don't make a metric frickton of money because people are good at math.

It's all a moot point anyway, really.

Spin 1: $10, lose
Spin 2: $20, lose
Spin 3: $40, lose
Spin 4: $80, lose
Spin 5: $160, lose
Spin 6: $320, lose
Spin 7: $640, lose
Spin 8: $1280, "I'm sorry, sir, $1000 table limit"

While it is true that you will ALWAYS lose in the long run with a martingale if you are giving odds to the house or you don't have an infinite bankroll, the house DOESN'T have an infinite bankroll, either, so in reality it could theoretically be broken before you are. Table maximums end that shite right quick and rip the guts out of a martingale strategy and dangle it in front of it as it dies.

Tell me how the probability is wrong

You are assuming that in the 38 hands you play each number has to hit. That’s not true. The chances of hitting any number on any given spin of the wheel is 1/38 no matter how many times you spin it.

OP:
"you would have a 94.7% probability to at least win your money back"


Wrong! Your chance of winning is 2.63% on every, single, role. Your chance of winning on roll number 38 is still 2.63%. How many times you roll is immaterial.

Not true when talking about probability of one number hitting. Over time when one number does not hit, the likelihood of that number hitting goes up.


Lmao

I’m laughing at the thought that someone of this level of intelligence could actually become the AG of Louisiana.

You're completely wrong. Past results don't affect future outcomes in a game like roulette. Every single spin has a 1/38 chance of landing on a specific number


He’s acting like they remove the winning number from the board after every spin, like it’s a damn Bingo Game or something.

Some people worry about potential employers digging up racist shite they said in TD, you just have to worry about them digging up dumb shite.
