How to beat roulette A good story about the cat-and-mouse hunt for someone who, in typical casino anti-hero style, is able to beat the odds and (at least for a time) walk away with a substantial sum of money from a high-end British casino. [archive link], via the amateur
It wasn’t the amount of money at stake that made the Ritz security team anxious. […] It was the way these three were winning: consistently, over hundreds of rounds.

There’s one surefire way casinos could stop prediction: calling “no more bets” before the ball is in motion. But they won’t.
That seems to be the nub of it to me. Never played, but I assumed that was the rule.

I'd like to believe that it is possible to predict the outcome of roulette in a sub rationale way, with 'feels' as it were, that you could train yourself by watching. It feels like an artifact of negotiating the gods cryptic press releases in times past, maybe a fundamental tendency to believe in the possibility of oracles. I guess I feel so drowned in the dogma of materialism (if that is the right word) that the idea of a slightly mysterious talent has so much appeal for me in contrast to the dirge like list of cognitive biases and gamblers fallacies that are so cynically exploited by the "gaming industry" and the democratic state's video poker and lottery games with their cold statistical precision.

If anybody hasn't read 'The Newtonian Casino' I would recommend it.
The true story of how a group of young physicists and computer scientists developed a computer to predict the results of roulette. They then smuggled the device into the casinos of Las Vegas, hidden in the soles of their shoes.

I have another theory. It's the dealer that makes the difference.
Here's a job where you are doing the exact same motion every 90 seconds for hours at a time, day in and day out. You develop a particular muscle memory without even thinking about it. A dirty dealer can probably put it in a zone whenever they want, a clean dealer can probably still signal their zone without realizing it.
And when you put up a video display of the last 15-20 rolls in view of everyone, including the dealer, you're literally inviting a bored dealer to try and hit the same number twice.

the idea of a slightly mysterious talent
I kind of like that it doesn't feel mysterious. If true, it's a kind of subconscious pattern recognition, focused on a very very narrow domain of interest. So much of what our brains do behind the scenes is pattern recognition; what patterns around us could we recognize if we focused on just a tiny sliver of the world exclusively?
Meanwhile if more journalists put as much effort into tracking things down as the author of this article did (or had the budget/time to do so), journalism would look different.

I remember seeing the original story 20 years ago, about a gang using lasers to knock over a casino. It’s quite pleasing to see the follow up all these years later.

my theory with roulette is that as long as the 0s don't come up it's even money
The 0's would have to be removed from the board completely for that to be true. Just the possibility of them coming up (whether they do or not) is enough to affect the odds.

This thread would be incomplete without a couple choice quotes from Croupier:

haven't got no class. I want to
live with a writer. Not a fucking
croupier. I don't even know what

Eudamonic Pie is the US title, Newtonian Casino the UK one, same book.
One of the stories out of that book was a discussion in which they discover that a croupier can throw particular numbers with some reasonable reliability. And, of course, most things that can be predicted by computer can probably be learned.
To some extent I wonder if the gambling business doesn't benefit from the occasional "no, really, {roulette, or whatever} is a game of skill, and millions of dollars, so glamorous" story. This is the sort of story I'd made sure got published if math education was getting a little too strong for the industry.

Zero may be your best bet in America.* The house edge on any single bet is 5.26%, and the probability for loss goes up the more times you bet on even payouts, and goes down with more single bets with 35x payouts. So bet according to how long you intend to roulette.
Odds Betting Straight Up Single Numbers
The probabilities when betting single numbers multiple times a row in American Roulette shift radically. Those bets which you can place on any single number, including the 0 and 00 are called “Straight Up”. The odds of winning such a bet are 1:37 while the payout is 35:1.
Betting on Single Numbers 5 Times
If you bet $100 on single numbers in American Roulette 5 times, the probability of winning at least once is 12.5% and with one win over 5 spins, you stand to win $3,100. The maximum loss is only $500 (when you lose all 5 bets).
Betting on Single Numbers 20 Times
If you bet $100 on single numbers in American Roulette 20 times, you need to win at only 1 of those bets to turn a profit. This happens in more than 41% of all cases.
Betting on Single Numbers 100 Times
If you bet $100 on single numbers in American Roulette 100 times the probability of turning a profit is over 49%. Those are the exact probabilities:
*America has two green spots, while Europe has one, making the latter much preferred, and the former a ripoff.

what's the chance that this is... not true? The house edge in roulette is pretty big, and a wheel seems pretty hard to predict. There are at least two possible explanations here:
a) it's possible for someone to predict roulette well enough to beat the house
b) Sometimes people say they can beat the house when they in fact can't (and maybe sometimes those same people are lucky, and do beat the house, and point to that as evidence of their prowess), and people like to accept those claims as true and write about them.
Anyone got evidence to support one explanation over the other? (I lean toward B, but who knows)

I'm guessing you haven't been to Vegas in a while because now they all have triple zero roulette.
Even worse, some casinos hide the third green position as a "logo" on the felt, which is a extra layer of bullshit on top of the 7.69% house edge.

that's just it -- if the 0/00/000 slots said "Bankrupt" like Wheel of Fortune and you couldn't bet on them, ISTM the house rake only happens when 0/00/000 are hit.
But I got the Monty Haul problem wrong originally so I'm not saying I'm right or anything, it's just the way I look at the actual cost of each session vs. the generalized e-v of the bets over the long run.

The house advantage is from shorting the payout from true odds. The scenario where there are a limited few bankrupt or losing pocket implies that all other pockets are payouts, when they are in fact mostly losing pockets.

They might be nudging people to the roulette machines, to save labor costs and to help pay for the new machines.

I'm not a gambler, but sometimes I think there should be legal restrictions on how and when casinos can change their own rules, and even if an exploit is found they have to live with it until the next opportunity where they can roll out a "patch". Or better yet, maybe walking through the door is a click-through license where you agree to the rules as they are at that moment and the casino is also bound to respect them as long as you are inside the building.
Like they couldn't force you to give up your previously-unknown edge because it wasn't against the rules when you entered the building, but they could still do all sorts of harm reduction like trying to distract you with free meals or (more extreme) closing parts of the casino floor entirely as you wander around.

Cat-and-mouse games are much more interesting to read about when the playing field has been leveled. It's no fun when the casino can just call the police and kick someone out just on the suspicion of them having found a way to beat the system.

I had a great system playing craps against my computer a long time ago. Looks like the odds have changed though. Wait for 6 or seven rolls without a 7, and then bet 2 on the field. If you lose, bet another 2 on the field. Then bump it to four for two more rolls, then 8 etc.
The old odds made it so that you would always win, unless you hit the table limit.
Made so much pretend money in that app. Seems like the casinos have nipped that in the bud.
