The Martingale Betting Problem
Вставка
- Опубліковано 11 жов 2018
- The Martingale Betting system claims that by doubling your wager after each loss, no matter how many times they lose in a row, a gambler is guaranteed to eventually win big. It’s considered foolproof, and mathematically it is… until it isn’t.
With the aid of a faithful blackjack-dealing robot friend, Kevin puts this 18th-century France gambling strategy to the test. How does expected value play a role? What about exponential growth? Here’s the real question: Does it actually work!?

You do this with bitcoin bits on a 3 to 1 roulette game.....
Oh hi, me!
but what about your video on probability? or the fact that a coin flip landing head 6 times in a row is 1.5625% or 1/64
It's like the old saying goes, "Do you know what casino workers say to someone with a can't lose system? Welcome."
I haven't heard that saying before, I like it.
Unless it really is. Then you shall be Photo banned in all casinos.

Some time ago I tried the martingale strategy.
I went in with $500
Got to about $2000+
And then lost everything.
U should try roulette
U have red and black - odd and even - and big or small and the same game
So when u see 3 or 4 red in a row u can make your bet
When u win u probably have more 3 or 4 odd/even or big/small in a row in a row
So u cut the risk by far

@@uwotmate3812 if there is no margin. If there is any margin you always lose.
@@uwotmate3812 mathematically you're right, but "over time" really means "infinity"... and you play in a real world scenario with betting ceilings and finite sources. In that case, the exponential behavior trumps the linear one easily.
If you can bet infinite sugar cubes and there's no ceil then you would always win.
The law of large numbers very much applies here, too. I used to play "dice games" with cryptocurrencies, and I understood every concept in play... I set myself up with an initial bet that, given what I had available, required a 27 loss streak of a 49.5% chance of winning dice roll in order to bankrupt me.
Yup, still happened.
*Never* underestimate the law of large numbers.

@Aiden Hafer I know right people can be so ignorant some times.
Vector is a cheater.
Just did the coin toss thing (because im sad) Got 98 heads to 102 Tails with multiple runs of 6 two runs of 7 and one run of 9 heads in a row.
I just did it in Excel to try it out :D
If you learn a bit of simple computer programming, you can replace minutes of boring coin tossing with hours of frustration and headaches!
It's worth it in the long run, though. OK, for this particular problem, spreadsheet skills would pay off more quickly. But spreadsheets aren't a viable way of teaching your robot to fist-bump.
@@nex lol I did it in a few minutes typing T or H into notepad and counting the results.
That can totally be a smart way of going about it. E.g. keep hammering T and H simultaneously to achieve decent randomisation, then use the text editor to do the counting in a few keypresses (character count function and find&replace). It's going to be quicker than writing the program, unless you're into competitive programming. (Which is an interesting hobby, but surprisingly irrelevant to both amateur and professional software development.)
But what I'm getting at is that once you've written a program that counts runs of heads, changing it to do millions instead of hundreds of tosses in a row, and to give you the average over many experiments instead of just the one, is super painless.
Still not as effective as just doing the math, but more fun IMHO. I guess it depends on whether you need enough precision to make it worth the confusion and headaches :)
Or you could just use Random.org
Summary of the 2 reasons why the Martingale Betting System won't work in a casino.
1 - There is a bet limit
2 - Your odds of winning are below 50%
The odds of winning doesn't matter with this tactic (except the chances on a losing streak are higher). To prove my point, try it with one dice, and count every time you roll 5 or 6 as a win. As long as you keep te stakes on your sugar cubes in the following pattern 1-2-4-8-16-32-64-etc. (or a multiplication of that pattern, and repeat after every win) your winnings will be your first stake times the time you have won.
How can your odds of winning below %50? If you play a fair game 1vs1 and both have the same skill, same deck, etc then you have %50 chance to win, because you olay again and again then your chance of winning increase.
Please if you can explain it to me, i would love to
@darthvader_alex you don't bet once you bet every time you lose so think the chance you win is 47%, you lose once, you bet again with this system if you lose you bet again. You get my point??? You Don't only bet one time but you bet after you win. Imagine it's a coin flip and you bet it's tail, the chance is 50% if you lose you bet again with this system the chance you win after the second bet is %75. You understand???
@slam zamillion I don't know where do you play blackjack but that's not how i play blackjack in casino, when i play blackjack with the dealer, even if i get bust, the dealer still need to playing (the dealer don't see my card and need to get minimum 17/18) and if the dealer get for example 24 and i get 22 then i still win
@slam zamillion mostly in a gameplay like you say it would be 3:2 if you win, but even if the dealer have 30% chance of losing, with this betting system you will still have more then 50% chance to win
When I was studying card counting it becomes kinda common sense that this technique should be avoided at all costs for the exact reason that if fails you're screwed
Vector is PAINFULLY cute!!

If you lost 2 games in a row.
Stop playing and take a break, because the game will put you in a losing streak. Teach the game you'll only play if you win.
...but the brain secretly likes losing 'cuz it believes that it can win; so, it keeps playing -- once it wins, it validates all the wasted effort it put in to all those games lost 'til it won.
Shruggz Da Str8-Faced Clown Be strong. Brain must resist!
That isn't changing anything though
Shruggz Da Str8-Faced Clown exactly that’s why that “I won’t stop playing until I get a win” is so popular in games. Even though it’s not beneficial at all. Take chess for example. Even if you have a high elo gain for a win and a low elo loss for a loss every game, just a few losses would make you have a loss overall if you stop on the first win
...The game is completely random. Vector is not AI; It can't learn either.
Some say this is exactly why casinos have table limits, however, some tables have no limit. I never knew this as the "Martingale" problem, but I was well aware of it. What I didn't know was the odds of those streaks. That's mind blowing and I'll have to write a program to see just how "random" Apple's random numbers are. This Vsauce guy is so damn interesting, I could watch these all day.

@@henryambrose8607 He was working on the video for a long time. Its a high quality video. He never quit.
I worked on a casino and this happened to me:
The probability of a royal flush on any given hand, assuming you get exactly five cards and don't get to exchange them, is 1 in 649,739.
The probability of any given two hands in a row being a royal flush is 1 in (649,739)^2 = 422,160,768,121.
That's the probability if you only play two hands and walk away and if you play many hands the probability gets better, but still: 1 in almost half a trillion is pretty unlikely. You would have to play only the order of half a trillion times before seeing this happen again. Even if you played a hand every second, you'd need hundreds of lifetimes to see this again.
So yes, I was the dealer and the player made like 10k $ in about 2 minutes.
You did forget to mention one crucial up-side to the Martingale strategy: Winning with a Blackjack after several losses in a row. Let's say you start at a $25 table and lose 5 hands. Your next wager is $800, and let's assume you get a Blackjack and the dealer does not. Your payout for that win is $1200, 3 to 2 odds (Some casinos and tables have different odds). So not only do you win your original $25 wager you started this losing streak with, but you also profit an additional $375 on top of that!
yeah, you could also lose consecutively, then losing again against a dealer with blackjack.
So you're saying I can win 9 times in a row
Yes, for a grand total profit of $225. The problem is that the equally likely loosing streak would cost you $25 575...
@@TheSwiftFalcon if you doubled your bet every time you won and had a winning streak then you could make out like a bandit
@@notquiteordinary almost same thing happened to me. i won 14 coinflips in a row winning 4k$ from 0.5$. that was a crazy day
@@notquiteordinary Yeah, but that requires either precognition or incredible luck to pull off. The point of the Martingale system is to guarantee profit without those things.
@@TheSwiftFalcon I understand what you're saying but what it seems like you don't understand is the way that black jack pays out, you always at least win your bet back plus winnings equal to your bet. Profits would probably be higher than 225. But idk let's see, 5, 10, 20, 40, 80, 160, 320, 640, 1280. Yeah it would be much higher than 225. It would be all these numbers added together. Plus you would have started with an amount equal to these added together, leaving with the total of these amounts x2
The problem is that your luck stats are too low

I've played too many games where I tried the martingale technique. It never ends well. I've seen losing streaks of up to 20 happen with a 50% chance of winning.
That is a probability of 0.000000953, I doubt you have seen many of those
and yet sooner or later it always happens if you actually try

I've been playing Baccarat for 45 years and never lost 14 in a row. I keep track of every hand played. If only there was a casino that would allow an original bet + 13 double-ups, I could live the easy life. P.S. Baccarat is easier to win at than Blackjack.

If it's a group of serious experienced players and don't take a year to make a move yes it's bit on the fast side I do agree but not inpossible
That’s kinda long for a single player and single dealer.
"Serious" players in casinos tend to play multiple hands at the same time, since each hands only have to beat the dealer to win.
i use online casino
so is use of that data was very helpful for my eyes to see.
Have you ever been to a casino?
I used to play a coin flipping game while in a live stream chat and at times, I swear, there was this evil presence controlling the flips. You see things like: an hours play and your longest losing streak is 9 so you hit another at 9 and bet is all figuring there is no way it could happen again and of course , it did. It always seemed that the more I tried to guess the streak it would up the record to catch me up. My eventual record of losses in a row got very high.
And Kevin said there is 1/3 chance a 9 streak will occur
... and by the 12th losing hand, you're indebted to the local Mafia loan shark, and might lose your kneecaps along with the next bet.
And then they bury you, still alive, in the desert with your brother on top of you.

In case anyone is wondering, that's the Prism Night deck of playing cards - the nicest of the Prism series. This deck looks fantastic - if you never use it. The deck isn't well made to begin with. It's printed in China, not Taiwan, so the paper stock quality is inferior. To compensate for this as well as make the cards tolerate humidity better, they are extra thick - some of the thickest cards made, actually. 10 of them measure over 3.13mm. This makes them unpleasant to handle compared to Cartamundi or Taiwan printed Legends or Expert playing cards. As with almost all black decks, when the sides get worn they lose the black color and once the edges start showing white the deck starts to look bad.

When I was younger I played around with computer simulations of using this system (I used the odds of hitting red/black in a roulette spin). No matter how I tweaked the parameters, the simulation would end up with an integer overflow at some point. When you play against the house there is one inescapable fact you can't overcome: In the long run the house is going to take a percentage of every dollar you wager, so if you keep playing, you are eventually going to end up with zero dollars. If you employ a strategy that involves betting billions of dollars, and you never stop playing, then you are inevitably going to lose billions of dollars. No magic math trick can get you out of that. If you like to gamble all night, the only sensible advice is to keep your bets so small that you are unlikely to go broke before sunrise. Better still: Don't play losing bets
martingale assumes infinite money, and actually for a finite budget it has a negative (or at best zero) expected value! In the long term the chance of bankrupting yourself being such a big deal balances out the more likely situation of you winning a tiny amount so that overall it's not worth it for any finite budget (or even if your opponent has a finite budget and they'll cut you off if you win too much).
no one has an inifinite budge. The casino has a budget that makes yours look like pocket change and they make the rules.

When I first started following the three Vsauce channels a few years ago, Vsauce2 was my least favorite one. It had a few interesting topics, but most of the videos just weren't my thing.
But I have to say that for at least the past year, I got to like your channel the most, partly because you're the only one who still uploads with a reasonable frequency, but now I also really like the content you make a lot more.
Thanks for these videos and keep up the good work!
Nicely explained! I wrote a VB Script back in 2001 to calculate the potential of betting systems against both Black Jack and Roulette, and was frustrated that the variables required to virtually guarantee success would mean sitting at casino tables for hours each day with very meagre return. That's why I'm not a betting man; all the games are rigged in favor of the house.
it gets worse when you factor in the house edge. in your example you assumed 50/50 odds but no casino gives odds that good. the smallest edge the house has is in blackjack where if you play perfectly, they have about a 1% edge.
you showed there's a 32% chance to lose 9 in a row after 200 coin flips, but if you only have a 49.5% chance to win a hand of blackjack, the odds of losing 9 in a row jump to almost 35%. go to the roulette wheel where the house has an even bigger edge and the odds of losing 9 in a row become 46%.
Yes, but it's even worse. Since you sometimes have to double your bet to get to that 1% edge so the odds of winning a single hand are lower than 49.5%. This math only works for roulette. What if you bet 64 cubes and you double your bet since you have 11 and the bank has a 6. If you win, you have 65 cubes profit.
Yea, when I've used the Martingale before I made sure the largest losing streak would have less than .01% chance of occurring. This usually means that the initial bet is very very small, so you can account for something like a 15 loss streak.
But his argument is 30 percent in 200, not a smaller sample size. That 9 consecutive in a row in a smaller sample around the size of 9, is much less than 30 percent. His argument is kinda collapsed here.
@@cloudcover540 An initial $1 bet will call for a $33k bet after a streak of 15 losses. Starting at a penny and we're still talking $328 for that 16th bet. How many places are going to have a 1 cent minimum with a maximum >$300?
@@rosen380 Pretty much all bitcoin gambling sites have a minimum bet of 1 satoshi, which is currently about $.0043. Max bets vary, usually around 5 btc so right now $18k. You can also play around with odds of winning, so each consecutive bet doesn't have to be doubled.

Although I think your conclusion is correct, one small thing: in Blackjack, unlike tossing a coin, wouldn't the results of hands be slightly connected (as long as the deck wasn't reshuffled in between)?

I used to use this strategy pretty commonly on a discord server with a lotto based economy centered around coin flips. Because there were no real life implications, those of us who used the system realized a lot about it because we went ham with it. Firstly, you should note that as you say in the video, losing streaks are incredibly common. Once I lost a total of 15 flips in a row. However, the same can happen with winning. If you’re lucky, you will make a lot of money. The amount of currency we’d bet was pretty similar to what you’d expect in a real bet. I personally made it all the way into the millions multiple times and others made it into the ten millions. We always saved a thousand or so no matter what but we definitely lost all of our money a lot. So in short, it completely depends on luck, but it’s very likely that you’ll either get rich or go bankrupt. And finally, statistically, you’d always be back where you started. When you actually think about it, statistically you should always end up with a net gain of 0. While the method is supposed to work well in getting you money, the system has no effect whatsoever on whether you will come out with more or less in the long term. You always go into it with exactly the chances of profit as the game. Know your game
Another great example of how mathematics don't always work out in the real world, but, also, you were getting hustled by that robot. You just need to get an unbiased third party to control the deck, because, clearly, that little guy will do anything to win.

Exelent quality content Kevin, i had fun watching it. Greetings from Croatia
You are the only thing keeping VSauce alive 😂
The strategy works better with a 1/3 chance of winning, with a reward of 3 times what you bet though, as each time you lose, the profit increases. (If you're still doubling your bets) You have to bet as minimal as possible though, as you have to account for the losing streak.
That's a terrible strategy. You're increasing your chances of losing by an additional 17%, which means longer losing streaks, causing your betting to snowball faster, meaing you approach the upper ceiling of your funds and betting limits faster.
2:55 even I couldn’t help laughing this time

Vector is just amazing.
I'm reminded of game theory. Tossing a coin is a good example. Say the coin shows heads six times in a row, your encouraged to think that 'chances' are the following toss is greater than 50/50 coming up tails.
But this in fact is untrue.
No matter how many consecutive heads show,
the following toss will always still be 50/50.
Same dilemma.
@Vsauce2: where can I get my hands on that awesome deck of playing cards!? Got a link for those?
Nobody can replace Cozmo.
Edit: Vectors still cool tho

I'm watching this in September, nearly a year after he first uploaded it.
Poor Vsauce2, thought showing glow-in-the-dark cards, would cause me to click faster! :)
so the revere of martingale should pay better? if you bet double every time you win. and bet starting bet every time you lose?
When will Vsauce1 finally make free videos?
Idk man
There's already a ton.
What is this question
Whenever I hear this betting strategy one of the fallacies that always gets mentioned is the fact that you only win your starting bet. This is only true for doubling.
For instance:
If you triple your bets instead of doubling and win at some point, then you are guaranteed to win at least half your last bet and it will be at least 1/3 times the total amount you bet.
If you quadruple each time and win at some point, then you will get at least 2/3 of your last bet and it will be at least 1/2 times the total amount you bet.
...
If you n-tuple each time and win at some point, then you will win at least (n - 2)/(n - 1) times your final bet and it will be at least 1 - 2/n times the total amount you bet.
Still the other fallacies mentioned hold true and are even stronger for the cases I mentioned. So it's not advised to go to a casino and dodecatuple your bets in the hopes to win at some point 10/11 of your last bet and 5/6 of your total bet. You will hit the casino limit pretty fast.
Tripling and quadrupling is a risky business.
@@patrickhecker853 That's why I said: "So it's not advised to go to a casino and dodecatuple your bets"
But that will lead to hitting table maxes far more often. At a $1 table with a $100 max:
double: a 7 game losing streak ruins it
triple: a 5 game losing streak ruins it
quadruple: 4 games
quintuple: 3 games
I simulated 200 hand sessions, 10000 times, assuming 50% odds (so more like a hypothetical roulette wheel with no 0 or 00 and betting on red/black/even/odd/1-18/19-36, I guess :))
On average doubling worked out to +$6 per 200; tripling -11, quadrupling -$2, quintupling +$3 and septupling -$1. Also did straight $1 bets and predictably came out at $0.
There doesn't seem to be any real benefit over the long haul to using different multiples. And the differences between them on average are rounding error relative to the total mounts you are betting.
FWIW, here are the best and worst end-of-200-hands for each:
1x -53 to +$51
2x -$1290 to +$126
3x -$2122 to +$625
4x -$2688 to +$929
5x -$2597 to +$1328
6x -$2450 to +$1445
These are just ending points- almost certainly there were times within 200 hand runs where you were outside of these ranges.
no casino is going to permit a bet spread that makes martingale betting viable, even *if* our imaginary bettor has a theoretical bankroll equal to infinity.
But might it be worth it if at the time you win you also have a chance of getting a black jack giving you also 20% (depending on the table) extra winning ?
Can you do a video explaining the math behind if you double your bet every time you won and then half your bet every time you lose? What would this result over the course of 200 black jack games?
While I agree with you in the basic problem of Martingale, this video contains several rudimentary errors that exaggerate the problem.
1) You examine only the possibility of a streak, but don’t take into account that a winning streak is fine. Not all streaks are equal in other words, but this video treats all streaks the same.
2) Starting with $25 is silly. Nobody playing Martingale is going to start with a $25 bet because of the exponential growth shown.
3) Part of the strategy of Martingale is that player blackjack pays back at better than 1:1, often 3:2. So if you get blackjack after a 6 game losing streak, in your $25 scenario, you make $425, not just $25.
In casino terms, you “stacked the deck” for your video.
Reed Smith if you were on a winning streak, you wouldnt use this bettinn system in the first place
I'm also wondering if he used "basic strategy" also... perhaps the methodology got a little screwed up, as the strategy could also impact your chances of winning and losing.
im a little bit curious. How can a betting system impact your chances of winning or losing?
Even starting at $1 (are there even $1 tables anymore?), a 5 game losing streak puts you at -$31. Follow that up with a five game winning streak and that puts you at +$5. There is a lot more downside than upside.
If there was a $100 maximum, a losing streak of seven games would require a $100 win followed by 27 wins (without hitting the max bet again) just to get back to break even. An eight game losing streak, now you need 127 wins to get back to even (again without hitting the max bet again)
--
3:2 wins would help, but "often"?? I get the odds of being dealt a blackjack at 4.8%. Of course, when you get a blackjack, the dealer also has a 4.8% chance of getting one themselves, so your odds of actually collecting that 3:2 drops a bit to about 4.6% of all hands. I'm not sure that puts much of a dent in the downside of the martingale betting scheme.
@@rosen380 many tables at vegas have a $10000 bet maximum. So if you start at $1, you would need a losing streak of 13 in order to reach the maximum. I used an online "streak calculator" to calculate that, with 3:2 odds of winning, if you play 1000 games, there is only a 0.4% chance of getting a 13-game lose streak
Now try driving to vegas with your friends laughing like hyenas the whole way with 8 bets only to lose it on your first martingale
these videos with math and statistics are amazing
Do a whole video about playing blackjack with vector please.
*Was never so early on a vsauce video.Nice*
*Edit:That robot is so cute.*
The duel arena has taken all my sugar cubes
even then, without counting cards, the house has slightly better odds making it even more likely you’d hit a big losing streak
