Step 1-Calculate necessary sample size to be 99% confident (1% significance level in statistics) with 38 variables (sections on a roulette wheel).
Step 2-Collect sample size 24 hours a day 7 days a week by using a team of players to record outcomes. If ANYTHING on the wheel changes (placement, cleaning, movement, etc) the sample will be deemed invalid and be discarded.
Step 3-Use statistical software to determine the probability that the roulette wheel is biased towards certain numbers or sections.
Sept 4-If the wheel is deemed not to be biased, move onto another wheel. If you determined the wheel is biased, exploit the wheel!
What do you think? I understand that the sample size will be quite large.
Quote: bighitter56What do you think? I understand that the sample size will be quite large.
To the point where collecting statistically significant data on enough wheels to find a biased example would not be likely to occur in the same lifetime as the discovery of a biased wheel. Of course, the location of your hunt might influence the results. The Wiz has recommended continental Europe; I've suggested Caracas and anywhere Argentine outside Buenos Aires or anywhere Brazilian outside of Rio de Janero in the past. Legal casinos in the US having biased wheels isn't something you'll be likely to convince anyone here of without first becoming the Joseph Jagger of Las Vegas, something that's never been done.
Even Dr. Wilson and his bias play crew back in the 1950s got backed off way before they could do any serious damage to the House bottom line. And even way back then he described a primitive mechanical computer that he observed in a Reno casino being using to monitor wheels for bias. They do that with real computers now, more efficiently than AP teams can.

Quote: bighitter56Just trying to use mathematics to gain an edge over the human/mechanical elements (most vulnerable) of the game.
Your best bet would be the Eudaemonic Pie, a book that dealt with two teams of physicists trying to clock a roulette wheel. One for the challenge and one for the money.
If by 'mechanical elements" you mean the construction of the wheel itself then the 1800s would have been perfect for you. Now the methods of construction, maintenance and surveillance are such that its a total waste of time.
The only vulnerability now other than past posting is the "sector prediction" that can be done since casinos find it profitable to allow betting to continue as the wheel slows down and the little ball is spinning around. If anyone can reliably predict the octet that is a prime candidate, he can get bets down. So speed calculations of the wheel and the ball might work (for awhile) but looking at an actual imbalance in the wheel or a slight variation in slot width is not worth the time invested.
My preference is to just bet the last five numbers spun. If the wheel's got any kind of a bias, this will cut the house edge by a little, and if it doesn't, it's no worse than picking five random numbers. I'm down 3.26% for the last 12 months, instead of the 5.26% I'd expect, but again, that could be just variance. It's been worth the money just to hear the croupiers talk about what numbers are due. My favorite was when one implored the table to bet a section of five numbers opposite the one he just hit, "because it almost always goes to the other side on the next spin". If it hit, "see! I told you". If it was close (within about six numbers on either side), "see! it was almost there!". If it wasn't in this 17-number range, he wouldn't say anything.
I love watching the mathematically challenged.

Hold on - he's not proposing a meritless system. His approach seems to make sense. I just don't think it would yield any favorable results. I don't think a wheel would ever be left untinkered with long enough to get the sample size required. Actually, to discover
anything usable would seem to require that the wheel maintained a repeatable bias even after being cleaned, adjusted, whatever.
Quote: FleaStiffHow would cruddy slot bias be shown. It just shows displaced randomness.
Perhaps you need to purchase my "Make $500 A Day Cruddy Roulette Wheel Moneymaking System!" I will let you in on the secret to making money with a cruddy roulette wheel, GUARANTEED! I normally sell it for $599.00 which you could EASILY make back in one day, but if you buy by 1:00 GMT tomorrow I will let you have it for $39.95!
Or maybe one pocket has more crud on it than others, so the ball squishes into place more, meaning you should wager on that number.
Who knows? I doubt it makes a difference that will overcome the 5.26% edge, but betting the numbers that hit recently isn't going to be worse than 5.26%, I don't have any illusions that it's going to be +EV.

Quote: SOOPOOI think if someone wants to actually help him they could give information on how many spins will occur on a roulette table over 24 hours, and how biased the wheel would have to be to state with some level of certainty that the wheel is biased enough to overcome the 5.26% house edge.
The answer to the second question is, in virtually all casinos, "too biased for the casino not to catch it before you do." You can only profit from a biased wheel if you can identify it before the casino does (and takes corrective action), *and* if it is sufficiently biased to overcome the house edge. The American game makes this virtually impossible at any properly-operated casino.
Physical appearance of a wheel is not really a good indicator of bias unless the wheel has been removed from its casement and you're observing the underside. This forum's go-to guy on Roulette bias play, Dr. Alan Wilson, found a very old and worn-looking wheel in a basement lounge in Reno in the 1950s; some of the numbers on the wheel were almost totally worn away and had never been repainted. He and his team got really excited and started taking notes. But they never did find a bias to it, unlike the new-looking wheel upstairs, which proved to be unquestionably biased as a result of a misguided (but essentially invisible) repair attempt.
Incidentally, I cannot recommend Dr. Wilson's book highly enough to anyone interested in Roulette bias play. Unfortunately long out of print; search Amazon for "The Casino Gambler's Guide" and you ought to be able to locate a reasonably-priced used copy. I feel like our bias play discussions here would be a lot shorter if everyone had read it. :)

Yeah, absolutely! Avoiding public scrutiny and review of the results is the absolute best way to both win respect of your peers, and develop great scientific discoveries. Way to go!
I agree. Or at least I would agree that there is a reasonable belief implied in his comments.
>and he actually is NOT proposing a 'system'. He is making an hypothesis that PERHAPS there is a biased wheel.
Yes, although that is more implied than overtly stated.
Let us perhaps shift our thinking momentarily away from a roulette wheel and aim it at the world of computers.
We've all heard the term "bug" and we all know that the term was coined when a programmer found a moth on a circuit board.
So if we restate the problem and be a bit more explicit about it then it becomes is there a bug in the system (crud) and is the bug a serious one that can be exploited for profit since the bug creates a biased wheel.
So let us say, solely for argument purposes, that yes. Crud on the surface of the slot edges and entrances does affect the ball. Let us say that the crud is not equally distributed. This ball that, but for the crud would fall on a red number actually falls on the neighboring number which is black because as the ball slows crud at the entrance to the slot does "something" to the ball's path.
The trouble I have is that its obvious crud has no effect until the ball is slow and approaching the slots and any interference with its "ordained" path is slight. If it were crudless one particular spin was ordained to be Seven Red but the crud caused it to be Black. However, the crud is more or less all over the wheel so any interference is just as likely to divert the ball to the adjacent slot all the time.
So you start out with a house edge of 5.26 percent and you wind up with a house edge of just about the same thing. The "bug" does not affect the house edge in any way that will allow a player to exploit the wheel. IF the player somehow knew that "the next spin would be Seven Red and the player also knew that the "crud factor" would make it actually wind up in the adjacent slot then it would be exploitable, but the cruddy wheel is acting upon the ball only at that final moment. And there is no way to say that a known cruddy wheel is anything other than 5.26 percent.
No it is a very popular topic, its just that people seem to believe that a bias simply must exist, but dirty frets and dirty slots seem to be a source of distraction to some and disgust to others ... but not a source of bias.Quote: statmanAdvantage play at roulette is an unpopular topic in this forum.

That's classic. Garcia-Pelayo made "many simulations" using the built-in RNG from MS-DOS QBasic.
The RND function in QBasic is a simple LCG, hardly the best choice for MC simulation because it has some pretty serious problems. Also, if the screenshot of the source code in that video was accurate, it's buggy in the same way that your simulator is buggy:
RANDOMIZE TIMER
X = INT(RND * 39)
X will be in the range [0 .. 38]. That's one too many for an actual roulette wheel. Whoops.

Not a land-based casino with physical wheels. I have done so for online casinos with RNG-driven games.
Alcohol tends to make roulette system players winners.
So the conventional wisdom is that in most cases the wheel is too good to be biased and in a few cases its too old or has suffered some trauma but its bias is discovered by the casino before there has been statistically valid bias determination which would consume a few weeks of some AP's time.
I guess somewhere there might exist a gaffed wheel but I can't jot down numbers all day long for a few hours or analyze them on a supercomputer to find out.
So what to do? Trek to Timbuktu and hope to find a gaffed wheel?
Wait for rumors of a gaffed wheel to reach me? That would be unlikely. They would most likely reach the casino first.
I mean lets face it folks, even a dumb croupier from a foreign country is going to detect bias before anyone else. He will either tell his supervisor or his brother in law. And this pre-supposes that the casino doesn't already have a computer that monitors the results and flags a few outliers.

For the benefit of the starter of this thread, MathExtremist is the member of this forum I most respect, however his specialty is slots, not roulette. He is one of the few people who knows what goes on inside those tricky boxes. He pointed out the error in my simulator earlier and I corrected it.
The video shows Garcia-Pelayo at his computer, but I don't see how anyone could figure out how to beat a wheel using a simulation. What you would be analyzing is your own wheel, not the casino's. The workflow would be Data -> Analysis -> Conclusion. The X2 analysis used by Murphy is the one used by the Wizard in response to an inquiry from Macau as to whether or not a wheel was biased. The thread is at (https://wizardofvegas.com/forum/off-topic/general/3760-is-this-roulette-wheel-biased/3/#post98249).

Quote: KeyserAnd just curious, exactly why would you need a super computer? For that matter, why would you need a computer at all
You don't need a "super computer", but the reason to use computers to detect bias is to free up manual labor from having to collect the data for subsequent analysis. Many major roulette vendors offer wheel reporting software. If a casino chooses not to look at the data, that's on them, but it's not like it's not being collected.
You seem to think that a single player (or team of players) can gather wheel bias information faster and/or better than the computerized monitoring system hooked up to the wheel. Why is that?

I don't believe I've ever commented about the speed of data collection. But since you touched on the subject, what makes you think casinos track the wheels?
I guess I should clear something up from the start. In the US, most casinos view the double zero roulette game as a carnival game. Very few casino have the software upgrade required to track these specific wheels, since they consider the game as being a suckers bet.
They do have the software on the rapid roulette games because of the shuffle master interface, but a wheel is not going to be removed from service if it's making money - even if it were to test positive for bias.
Only recently, have a few casinos aquired to the newest software interface available with the latest TCS readerboards.

Most casinos in the US regard the games as being for suckers, and for a good reason. In Europe and other locations wheels are carefully scrutinized, but not here because of the extra zero. Casinos here are run more like the parks and rec. dept found in most cities. Most casinos here also won't pay for the upgrade required. They simply want the cheapest hubcap that they can get that will spin for a long time.

So take it easy on the flagging people.
Take any random variable (wear/dust/grime/defect) that forces the ball off the track at a set point. Now should the ball only possibly cover even 90% of the wheel from the drop point, there is an edge. Remove one number from a European wheel and it's a dead even game, remove two and the player has an edge.
As the original post states, there will be too many hours lost scrapping data samples due to cleaning and routine maintenance.. better to recognize a bias that develops quickly and capitalize..

Yes, you actually wrote what's going on there, "random variables". If the wheel where truly-random, the ball would NEVER drop. It's those effects you mention which make the thing variable. Besides, do you really even believe that some dust, etc, will rule out 10% of the drop-zone?

Quote: KeyserWhy?
That is a fair question, the thing being not cut-and-dried as the indeterminancies posed by perpetual, straight-line motion (or translation). But a watered-down version of that, analogous to the sort of randomness of the irrational numbers' decimal places, the square-root of seven, eg. Unlike those numbers, which are already set out for us, if not infinitely-at-hand, live roulette involves some processing. And that's where those "frets", "diamonds", and even the dirt, egs, come into play.
In practice, the former sort of randomness exists primarily and seemingly-sporadically in what's commonly called "quantum states"... a finite (in positive matter), mapped-out (by probability) set of rules for the tiny, "loose" wave/particles thereby governed. So far, and despite much effort, no one has in any substantial way, theoretically or physically, unified quantum-science with the other sciences... to bring our world's understanding into the quantum's. A quantum-state remains that, separate and aloof, either-or, until its "wave-function collapses", supposedly upon having incredibly-quickly (forward and backward through space-time, and back to itself,) has "physically" calculated out enough optimally-possible paths for the universe to continuously yield a "fresh" one for everyone/thing involved. It's either that sort of completely-unpredictable, unstoppable randomness, or the predictable (, even if we don't yet posses the practical tools to well do so,) outcomes like roulette; but never, it seems, both at once.
The math, whichever, is relatively-easy... it's living and breathing it, that's the hard-but-fun part. How to begin to explain things most mathematicians take for granted, like infinities (which often cancel out on those own), or the physical bases for their operational ones?
