Monte Carlo methods – Why it's a bad idea to go to the casino

When people go to vegas for a weekend, they might have a number in their head they are willing to gamble. If they dont, then that number is their bank account balance. Then they start flipping coins, and often they keep doing this until they go bust. They rarely cash out when up but they always lose when they go bust. They scale the bets as their bankroll grows. Essentially they are flipping coins for infinite time and just waiting to get a bunch of tails in a row, which is inevitable. The behavioral factors are bigger than the house edge.
The idea that people are rational is also absurd. Some people are driving to the slots _because_ they are depressed. Or they are there for fun but they lose a bunch of hands in a row and tilt and now they're betting everything on a longshot to win it all back and win some because they dont want to self-identify as a 'loser'.
You can only spend so much money on drugs and sex. Gambling is the only vice where you can lose billions. And these days, all you have to do is pull out your phone to place a trade or a bet.
"Flipping a coin until you get enough tails in a row" is a really good way to describe long term gambling, though. I'm gonna borrow that.
It's not. The correct way is saying 'flipping a weighed coin'. It can be weighed in or against your favor. If it is weighed in your favor, then you will never really have the 'until' part (i.e. get bust), if you also manage your bankroll wisely.
That's how I read it, at least.
If they would allow me to play a +EV game I can crush them even if they had infinite bankroll by varying my betsize. The 'random walk' argument only works for fixed bet size.
If a business offered a positive EV gambling game, it wouldn't be called a casino and would only last as long as the venture capital lasted.

There are a few catches though. Mostly if you play perfectly (which is not simple) the most you can expect to make is less than eight dollars an hour.
Turns out, you have to go surprisingly high for this to be true/effective on the long run. And the casino will cut you off way below the limit (i.e. there's of course a maximum bet). Plus, with this strategy, each win is a small one... but when you lose (hitting the max bet), the loses are significant.
This is the St. Petersburg paradox: https://en.wikipedia.org/wiki/St._Petersburg_paradox
An approach that I've found to be useful, and have personally used in Vegas:
- Always start off each session with a fixed $X in chips, even if you're flush from previous winnings
- If at any point during the session, you get to $2X or $0 in chips, end the session immediately and cash out everything. Even if you're on a "hot streak"
- Bet large enough that you will get to $2X or $0 in a short/moderate period of time. The longer your session drags on, the lower the likelihood of getting to $2X
- Once a session has ended, have a cooling off period. Eg, no further gambling until after the next show/meal
If done right, gambling can actually be extremely cheap. With a house-edge of 0.5%, you can gamble $10,000 and only lose $50 on average. This makes it far cheaper (and more exciting) than eating out or going to shows.
The usual disclaimers still apply: only gamble what you can accept losing, no more
I think gambling can be fun if you limit yourself and don’t take it seriously. Trouble is Vegas is good at making you feel special. And they serve free booze.
I also the approach you mentioned above, never more than say 20 bucks with maybe another 10 as hard reserve. Quit when I'm ahead by a factor of, again like you, roughly 2x. And playing smaller amounts, meaning not everything at once but reasonably high, provides enough entertainment gambling for at least an hour. So in the end, even if everything is lost, I had my fun. And let's be honest, 20 bucks for on hour of fun isn't that bad a deal.
Fun fact: In total I'm like 100 bucks on top right now, paid for a pair of Nike sneakers for my son back the day!
I wonder what you find entertaining/fun about this. I've been to casinos a couple of times. The only parts I found entertaining were observing people and the free drinks.
Paul Newman - The Color of Money
And yes, the other people are the sometimes the funniest part. And the saddest. Seeing people using what is my month salary in around two hours... On the other hand playing only one or two bucks per game and others reaction is fun.
Personally, my gambling strategy is simple. Whatever amount I’m gambling is considered spent in exchange for the “fun” I get. I expect to walk away with zero. If I’m winning I like to go double or nothing right before I leave on black at roulette, just for the hell of it.
Start with X. Whenever you get above X, skim the surplus and store separately.
You've now capped your losses at X (aka the price of the game night) and feel like you're winning when you can skim some money off your pool.
They took only their winnings and used it to buy entertainment in the casinos where they gambled, which went a long way with the military discounts.
I want to say their original X was $500 or so, and it funded several years of local entertainment.
Weirdly I seem to do quite well in the casino and often have evening where I leave the casino 2-3X ahead of where I started.
My luck at football betting is terrible, I'm even worse at horses.
When you're up it's quite the thrill. You weather the downs as a cost associated with the particular vice.
I enjoy "emotionally hedging" sports events - if I want X to win I bet on Y
Do you play any other things (sports or games)? Do you not ever go for low percentage / high risk actions if only for the pleasure of occasionally see them come good?
Think bicycle kick in football, haymaker in boxing, high stakes play in poker, 1-frame combos in Street Fighter, technically difficult riffs in a musical jam.
I feel your line of questioning locks money and all its uses to rationality. Money can be an instrument for pleasure and for many, risk-seeking is a pleasurable activity.
It's really fun to spend money that you feel just fell from the sky. If you employ the right strategy you will still come out ahead 40-45% of the time, and those times can be quite memorable and fun.
You will definitely take losses in the long run but if you play well within your means, they won't have any impact on your life.
Is betting your job or an entertainment for you? If you see it as a job, a means to make money, I feel like that's unhealthy.
When I go see a movie, even if the money is "lost", I still enjoy it. You go to the movie for the emotion it makes you feel, just like you bet for the emotion it makes you fell. It's the trill, the chance of seeing big wins.
At the end of the day, casino can be actually quite cheap if you don't bet too high and there's free drinks too usually ;).
Sure that emotion is simulated, you won't actually win money. The same is true for the emotions you feel during a movie. The fear you may feel in a horror movie isn't real, you aren't in any danger.
In both case though the emotion is really there and that's what you pay for.
That's exactly why loot boxes are essentially gambling even though you get no monetary gains from it. It plays on the sames emotions, the same thrill.
Everyone is attractive, powerful and sophisticated. People look on, impressed at his daring. Everyone has a bow tie on. Beautiful women hand him free drinks with a smile. The atmosphere isn't even slightly tinged with the desperation and regret of gambling addicts.
I can understand losing $50 a day to live out that fiction.
I have no idea whether any casinos offer that experience - the gambling things I've seen in my country have all been far more tawdry.
Had the OP actually properly described how to build a useful Monte Carlo simulation, you could find your article, get the actual rules, run a simulation and check whether 33% was in line with expectations.
> The first time I was in Las Vegas I sat down and figured out the odds for everything, and I discovered that the odds for the crap table were something like .493. If I bet a dollar, it would only cost me 1.4 cents. So I thought to myself, "Why am I so reluctant to bet? It hardly costs anything!"
So I started betting, and right away I lost five dollars in succession--one, two, three, four, five. I was supposed to be out only seven cents; instead, I was five dollars behind! I've never gambled since then (with my own money, that is). I'm very lucky that I started off losing.
One time I was eating lunch with one of the show girls. It was a quiet time in the afternoon; there was not the usual big bustle, and she said, "See that man over there, walking across the lawn? That's Nick the Greek. He's a professional gambler."
Now I knew damn well what all the odds were in Las Vegas, so I said, "How can he be a professional gambler?"
"I'll call him over."
Nick came over and she introduced us. "Marilyn tells me that you're a professional gambler."
"That's correct."
"Well, I'd like to know how it's possible to make your living gambling, because at the table, the odds are .493."
"You're right," he said, "and I'll explain it to you. I don't bet on the table, or things like that. I only bet when the odds are in my favor."
"Huh? When are the odds ever in your favor?" I asked incredulously.
"It's really quite easy," he said. "I'm standing around a table, when some guy says, 'It's comin' out nine! It's gotta be a nine!' The guy's excited; he thinks it's going to be a nine, and he wants to bet. Now I know the odds for all the numbers inside out, so I say to him, 'I'll bet you four to three it's not a nine,' and I win in the long run. I don't bet on the table; instead, I bet with people around the table who have prejudices--superstitious ideas about lucky numbers."
Nick continued: "Now that I've got a reputation, it's even easier, because people will bet with me even when they know the odds aren't very good, just to have the chance of telling the story, if they win, of how they beat Nick the Greek. So I really do make a living gambling, and it's wonderful!"
So Nick the Greek was really an educated character. He was a very nice and engaging man. I thanked him for the explanation; now I understood it. I have to understand the world, you see.
Speak for yourself.
For those that do like to gamble and are not addicted, craps and live 4-8 no-limit hold'em table, 1-2 if you are new. As for pulling out the phone, Liverpool has given me a lovely year.
This opposed to physical, direct investments which are much easier to control, but more labor intensive. Control stock (as in having a control stake) is in-between, and extremely rich people game.
That is not far from truth, I use to work for a company that owned several Casinos, we use to have "whales" spending more than 100k each month, sometimes they lost everything so quick that we gave them 50% back or trip to Bahamas / Paris, Anything to keep them happy and coming back.
Given that not everyone's account balances are zero, plenty of people gamble for entertainment without going broke. I'm occasionally rational and enjoy playing craps. It is social, rolling dice is fun, and it gives a huge range of betting opportunities. I will also almost always play until I lose. The point is to have fun playing, and not to win money at a game where my EV is negative.
If I want to win money, I play poker. The problem with poker is that I'm not good enough to play games where I can win big (10s of thousands) money. The second problem is that playing winning poker is a grind and can be quite boring.
The real cause of the financial crisis -- An MIT Blackjack Team perspective by Semyon Dukach http://semyondukach.blogspot.com/2009/01/real-cause-of-finan...
I beg to differ, good sir.
Sad how prevalent this is. At least I have to fly to Vegas - the stock market is on my phone.
MCM are not strong if the tail variance isn't an important feature of what is being modeled. I've seen simulations where the modeler starts with an analytic model - from which they could trivially calculate the mean and variance of a KPI - then used a MCM simulation to find out essentially what the mean and variance of the KPI.
So I get that this code is just for illustrative, educational purposes. That is fine. Well done Christof, thanks for the contribution to education. But if anyone is actually using MCM to simulate well known probability distributions they should really put the effort in to learning how to work with well known probability distributions. I feel pretty confident that simulating the Bernoulli in a professional setting is a mistake, because I've seen it done and it was a mistake. For amateurs who aren't confident with math then they can use MCM if they like; but statistics is dangerous and they should be aware that they are using the wrong tool for the job and it is a tell they will get other things wrong. You get a lot of insight from a good analytic model.
If there is some interesting tail issue (eg, maybe after 3 heads there is guaranteed to be a tails and your insurance contract pays out on a tails) then sure, use MCM. Great tool if you have the right problem.
or would you rather perturbate your variables and resolve mean and variance. My philosophy drives me towards the computational approach over the analytical mathematical approach.
The calculations should be arriving at the same numbers in the end, and implementing a simulation vs. an error propagation tree isn't going to favour the simulation for simple scenarios.
MCM is great for when doing usual error propagation is infeasible. It is sloppy when the error propagation could be done with a one or two analytic formula. Simulation isn't appropriate for problems that are easy analytically. For example, in practice, most of the examples in the article are not suitable problems for breaking out MCM (and although the author probably knows that, maybe not everyone on HN does). The Pi one might be a standard application, but even there Pi in particular is not a great choice for a showcase because Pi has some very nice analytic approximations.
If a modeler has assumed two different models of a situation and are getting vastly different results then that is evidence something is wrong, but it is also evidence that the modeler is out of their depth. It is not appropriate to fit two different models and then claim that the differences are delivering insight. The differences are revealing big gaps in the modelers understanding of key influences, rendering both models highly suspect. They should not be creating models, they should be putting more time into understanding the thing they are modeling.
There are times when a modeler would have two different models, but they should certainly not be surprised that they give different results. Indeed, they should be assuming two different models because they are going to give completely different results. There will probably be other edge cases, but in my experience they are rarer than people just making mistakes about where MCM is appropriate.
Using it for an answer you could easily get analytically isn't very useful outside of education/fun.
For something as straightforward as Bernoulli, where you plug values into a formula and are done, there is no reason to use MCM. However, I am in agreement that in more complicated cases (e.g. a probability distribution is based on some result of one Markov or Markov-like calculation — or possibly multiple), and the theory is slightly or much more complicated then there is a lot of value in Monte Carlo methods.
If I were using simulation it is because I think that something fishy happens in extreme events (eg, maybe stock returns all starting to become highly correlated in a liquidity crisis, destroying i.i.d assumptions). Or as other commenters mentioned because the thing being simulated has a distribution that is not analytically tractable. But there has to be some phenomena in there that is more complicated than standard distributions or a steady state Markov model, because they are more productive models when they work.
> Is there a way to constrain the MC sampling to the tails of a distribution?
You could sample 100 numbers at a time and drop out the middle 95? The question is maybe not well posed.
This example isn't so much different; MCM = screw driver, problem = nail and learning proper statistics = driving to the hardware store and buying a hammer.
The only aspect where the comparison is somewhat lacking, is that the costs of having a hammer (both aquisition and storage) are minimal compared to in-depth knowledge about statistics.
The aim was to create a single page anybody could link to that proves without a doubt the abysmal odds of making money off the roulette with the martingale technique. Instead of pre-written probabilities, charts and 'obscure complicated math' that people could easily dismiss. I wanted to give people the ability to run simulations of playing at the casino in the browser. The idea being that people would end up building the probabilities/charts themselves through simulations.
It is running Monte Carlo simulations inside the webpage and outputs the result as charts dynamically using js and D3. What it does is it repeatedly simulates going to a casino with a certain starting amount of money and an objective of how much you want to win. It then plays the roulette using the martingale technique until you got your target winnings or you lost your money.
Unfortunately I don't think I wrote the article really well and the 'generate yourself the charts proving it doesn't work' doesn't come across really well. I should have put a 'run' button instead of needing a page refresh for a start.
I once saw 13 be hit 4 times in a row (and once more within my 45 min rotation at the nearby table). Don't think I've personally seen any other 4 number streaks.
A lof of people won a lot of money during the two last ones.
I've only played a few slot games online and visited a real casino as a guest once, where I bought chips for $150 and left with $5400. The goal was losing it all and at the end I was putting $1500 on the table at a time, and dipped below $500 just a few minutes before making the $5400 and leaving.
One of the best nights I had while working was a regular from the poker room coming to my Black Jack table trying to win back the $15k he was down. Had the 'chef' (senior position at the casino floor, poker equivalent would be 'brush') there talking to him since he wasn't doing well. He managed to win it back which was a great relief.
- Many players were plainly cheating in some way, by marking cards and sometimes colluding with the dealer, but the casino didn't appear to mind because they were cheating in an ineffective way and still losing money to the house edge.
- (Related: you would just be banned if you won an amount of money that showed you were beating the house edge: see also the Phil Ivey lawsuit)
- Some players were gambling large sums of money generally on games with a small house edge, and looked bored like they were there to do a job. I assume from their behaviour they were laundering money.
Contrast this when I was at the Monte Carlo casino in Monaco where they somehow sucked the fun out of craps.
European casinos seem to be selling something else.
I wish that more depth was presented here: what percentage of the time do you get favorable vs unfavorable outcomes with each strategy? For further depth, use different types of players (with different exiting conditions).
Perhaps I should write such a blog post at some time..
Same offer goes for anyone else who's putting a lot of work into a post they hope will interest HN.
Yes, you can at times win and come out ahead. But on the whole, you will lose. My father's advice has always been: "Son, treat it as entertaiment and spend only what you can afford to lose like every other form of entertainment. If you think you can win, you be the fool and will lose more than you can afford." I have also found that gambling institutions are so depressing a venue to be in.
3:2 payouts for Blackjack were gone years ago, but more recently no even money for Blackjack if dealer shows an Ace, only split once for two Aces...not worth it at that point.
The one and only time I was convinced to give roulette a try I lost everything pretty quickly (I mean the small pot I'd set aside for gambling - I'm not stupid enough to keep withdrawing money and bet more than I can afford).
Seems blackjack can be pretty lucrative if you're willing to walk away at the right moment. I seriously doubt it would work as any kind of long term strategy, however. Of course you also have to have the discipline to spend the rest of the night drinking beer and watching your friends get poorer and poorer.
Gambling: Return on Investment < 0
For the casinos, it's an investment, for the customers, it's gambling.
Similar conclusion, once u win enough, you leave; once you lose enough, you leave. Never bring your whole bank account to a casino, or the figures will be move closer to 0.
Of course you should always try to have a deeper understanding if you want to make serious conclusions. But I felt this article got the concept across really concisely! Nice work.

FWIW I was looking a betting website recently [0] and they were offering DOUBLE your initial deposit for signing-up, up to $1000. So to reiterate, they are willing to give up to $1000 for FREE just for creating an account. All I can imagine is that they would only do this if the numbers are vastly not in your favor.
[0] I'm not going to post the name of said website.
The mathematics doesn't really matter because if you find a systematic way of winning then they just ban you.
No, for creating an account, funding it AND making a significant amount of wagers. The details vary by site, but there are always restrictions in the fine print -- either you only "earn" the bonus a few percent at a time, or you aren't allowed to withdraw until you've made enough bets, or some similar restriction. I'd guess that some or all of the "free" $1000 is inaccessible until you've made a 10x rollover, or $10,000 in wagers.
I did this. Bet the bonus on some super low odds trots race to place that was as good odds as anything to get my money back and then bet the other half on a 36:1 long shot that Bernie would win the nomination.
I got my money back with the low odds Trotter, otherwise I would have bet the balance on another low odds event. Obviously didn't win the long shot.
Not sure why I did it as I don't normally gamble but generally curious and though it was a fun way to risk a small amount to potentially win a "free" holiday.
Scarne’s Complete Guide to Gambling
What you will probably take away from this book is that the house wins when you win. And the reason they win is that they don't pay actual odds.
Take the roulette wheel as a simple example. There are 37 (or 38 in the case of 0 and 00 wheels) slots. If you bet on a single number, they pay 36:1.
TFA mentioned doubling down when you lose. That's known as the Martingale Strategy. As banks and real estate lenders discovered in 2007, regardless of your model, there will be some condition where the near-impossible will happen.
If you want to use the roulette wheel again as an example, and even if you want to ignore the green 0/00 slots, you have half black and half red. You can simply play one color and double your bet if you lose... until you finally win it all back.
The problem there is that while it's true that for millions of spins, about half should land black and half should land red... but in short periods it is possible for there to be 10 or 15 or 20 or more spins of the same color. We can all do exponential growth, so it's easy to see how doubling down will empty your wallet eventually.
But just to be sure that strategy won't work, most casinos will set a table limit. That limit will be designed to prevent you from doubling your bet too many times (5-7ish times? depends on the place). Of course, if you discuss in advance with the casino, you may be able to set a personal table limit based on your initial bet. So you can bet 1 million on the first spin in order to set your table limit to 1 million. But that's truly a gamble.
There is one element you can control when gambling: that is when you increase or decrease your bets, and ultimately when you stop playing.
Yes, you can count cards in blackjack; but that's generally frowned upon (where "frowned" means you will be escorted out and told to never return -- and they are very serious). Even levels of indirection of counting such as employed by the fascinating experience of the MIT crews of yore (https://en.wikipedia.org/wiki/MIT_Blackjack_Team) have become obvious. So the short of it is, unless you only play a little, bet big, and get lucky for your limited period (and then stop so you don't get banned), you will otherwise lose more than you win.
Now for my personal opinion :). Casinos used to be a fun place. Now they are so optimized and commercial that they are like Walmart. Yes you can go, but you'd probably rather not. For modern thrills, we now have crypto exchanges with 50:1 or more leverage.
No matter what you bet, your take is only equal to your initial bet * number of rounds/hands played.
You can, for a given number of plays, use Martingale to make the odds of winning greater than the odds of losing. However what you can't do, is change the expected value of that set of plays. So what you've really done is created a situation where you have a high chance of winning a small amount of money, and a low chance of losing a lot of money.
(There's also the gambler's calculus that while they're losing money playing, they're being comped drinks/rooms/meals/shows/etc at a resort.)
Played until my wrists ached on $5.
It's not that the advantage is small (if it were, the MIT team would never have been so successful in the first place). It's that most people who try aren't good enough to do it well, so the casino is happy to let them try (and fail), thereby making money for the casino.
USE the count? Typically no, unless you're betting very small and consistently.
Basically, the way to annoy them and either get kicked out or only allowed to flat bet is to vary your bet size with the count (E.g. bet a lot when the count is favorable, and the table minimum otherwise). That's the only way to really make money counting. Much easier to detect these days with the eye in the sky.
You can use the count to inform certain decisions that lower the house edge a bit, but typically not enough to actually be +EV. For instance, insurance is normally a very bad bet, but at certain counts it becomes +EV, but not +EV as a whole to make it worth...having to play blackjack.
Casinos will shuffle all the cards before you have a significant knowledge advantage. They may adjust their shuffle point based on whether they detect a counter. If there are no counters at the table, then it's more efficient (for the house - hands played per n period) to play until close to an empty shoe. But if they detect a counter, they may shuffle much earlier - half shoe even. At that point, the counter has very little advantage.
Regardless of the rules and what casinos choose to allow, they will stop a player that they believe will, over time, really hurt the house. In some cases, however, skilled players will be allowed to count and win big for a period if the house believes that player will take that money and lose it elsewhere on the property. Or if that player is influential and attracts/brings other less successful or disciplined whales, the house may ignore the cost of the one successful counter.
In the end, it's about bottom line... unless the player pisses off someone important on the property. In that case, it doesn't matter what the player does - they're gone, banned, and probably blacklisted from other quality properties.

(with slight modifications), then you get continuously-updated histograms of the results.
1. If I could find an optimal way of playing the game to maximize my profits.
2. If I could find a bias towards certain numbers.
The result was:
1. I found a way with 1/3 chance of winning big and paying back all expenses you played for the past 20 years. It is a significant investment and everyone will think you are crazy, but you have a very high chance of early retirement.
2. I found no obvious difference between the frequency of numbers.
The idea is to spread your betting numbers as far apart as possible in order to follow the normal distribution. If you reduce the overall gap between your numbers, your chances of winning is significantly reduced.
[1] http://www.millipiyango.gov.tr/sonuclar/_cs_superloto.php
AFAIK uniform distribution means any number is equally likely to be drawn, regardless of distance to your other picks.
Just to check if I got that right: does that mean that playing 333333 and 666666 in a 6 digits lottery had a higher chance of winning that picking 333333 and 333334? If so, why? And, since playing more numbers will reduce the overall gap. Does that mean the optimal strategy is playing a single number?
Did you test your method via simulation? I can't see how it works with my little knowledge of statistics. Can someone chime in?
Not exactly sure why.
But it's only a part of the problem. Second part - money and gaming easily can be addictive like drugs.
Not the drugs are addictive, feeling good is.

What's interesting though is that it's easy to observe a ton of gamblers for a long time. And since there is usually also a chat, interacting is also possible. These sites usually have 14 numbers for roulette where 1-7 is red and 8-14 is black, 0 is green which gives 14x your bet. Red and black give you 2x.
If you observe enough gamblers long enough (which I did), you see the same pattern over and over and over again. It goes like this: 1. Gambler starts out with a random amount of money (could be high or low). 2. Gambler wins big (usually like 1-3 times on green) 3. Gambler feels lucky and gives out money to 'passive' beggars* in the chat. ( Sometimes I would feel bad for the gamblers and hint them in the chat that they should cash out, no one ever listened ) 4. Gambler continues and might win some more, or lose some but not all. 5. Gambler has been betting for such a long time that he/she is back at where he/she started. ( Beggars keep begging but gambler says he is down so doesn't give out money right now ) 6. Gambler suddenly wins big on green again (or went all in) and feels like a king again. 7. Now Gambler cashes out (by buying a skin) the money with which they started and continues with what his/her leftovers. 8. Gambler loses the leftover money on the website. 9. Gambler deposits the skin that was previously withdrawn again. 10. Gambler loses everything now and the beggars focus on a different big gambler. 11. Gambler usually comes back within a week or month and loses more money. 12. The cycle continues.
* People, usually kids, that lost their (usually small amount of) money earlier and our now cheering for some big gamblers so these gamblers might send them money on the website.
I personally also lost a (for me) quite big amount of money on these sites over a decent period of time. Later, I was able to sort of stop my addiction and I made a bot which predicted random results (red/black/green) in the chat. It got me like 30 dollars of tips from people that had probably used the bot but the website changed some things so my bot stopped working and I have been too lazy to fix it.
Last thing: I also kept some stats of the roulette because I had to know the timing of the roulette so my bot wouldn't predict if it was already rolling. I added an extra feature for myself so I could see how many times red/black and green were rolled and how many times my bot got the predictions right. Obviously this always ended up in a big loss for my bot (in terms of predictions, I did not bet money with my bot) in the long term.
Playing a minimum bet for a long time, then suddenly increasing to the max near the last half of a shoe is a good way to get a casino to ask you to stop playing blackjack.
Of course you should always back yourself. So more power to you if you're winning in this way. At least you get to keep playing :)
> The System, a Channel 4 special in which Brown shared his "100 percent guaranteed" method for winning on the horses, was first shown on 1 February 2008.
> The show was based around the idea that a system could be developed to "guarantee a winner" of horse races. Cameras followed a member of the public, Khadisha, as Brown anonymously sent her correct predictions of five races in a row, before encouraging her to place as much money as she could on the sixth race.
> After Brown had placed a bet of £4,000 of Khadisha's money on a horse in the final race, he explained how "The System" worked. He had started by contacting 7,776 people and split them into six groups, giving each group a different horse. As each race had taken place 5⁄6 of the people had lost and were dropped from the system. Brown had a different person backing each horse in each race, and one individual, Khadisha, won five times in a row.

One example where he had a good yield was playing shitty races (there are different tiers of horse races, from fancy ones like the Belmont Stakes to down to older or younger horses) in bad turf conditions. He’d look at what horses scratched and which trainers usually scratched and make different bets as the odds would be screwy and in his favor.
He bought toys with his winnings, and his process was making him a decent buck, at least until he retired and we lost touch.
If casino gambling hadn’t gone mainstream, there would be a lot of interesting activity in throughbred racing — now it’s a legacy backwater sport.
