How can it happen?

There is a player at the casino which I work that consistently wins on roulette, and by consistently I mean around 98% of the times he visits. He is one of the higher end players however prefers to play on the lower limit tables. His betting seems to follow that he will bet on the neighbors of the last winning number, both on straigh-ups and splits. He plays on multiple tables for up to 8 hours and a time. Management have tried all things to curb his wins, from ensuring the wheel speed is at a faster rate, ball speeds are varied, maximum wagers reduced and differing ball sizes. All wheels are scalloped to increase randomness when the ball drops. Nothing seems to work. Seriously, after a 4 day visit he will be winning in excess of $10k approx 95% of the time. He may have a loss one day but will always recuperate the loss in the other days he's here. Statistically there is no way that over a period of 6 years he should be consistently winning like he is.

Is there anything else that anyone can recommend might help?

You have God visiting your casino? (He's throwing in the occasional loss to make himself look more natural.)

Haha...maybe.

But seriously, this is becoming a major pain in the butt for management who are putting it on to us.

Any suggestions???

By multiple tables I assume you mean that he is not following a particular croupier. Does he attempt to shake hands with anyone?
Does he sit in the same position with reference to the wheel each time?
Does he have any confederates playing also?
When you record a series of spins when he is NOT present, would his strategy prove profitable just as often as when he is present?
Look at the wheel under a multi-spectral light, any streaks of any sort?

Stop sweating it and let him play any way he wants. Someone's got to get lucky once in a while and if management can't understand this simple fact then they have no idea how casinos work and should either take a statistics couse or get another job.

On the other hand he could be from the future.

No, he doesn't follow any particular dealer, usually stands at the far end of the table away from the wheel and doesn't have anyone with him. No physical interaction is permitted with staff, so no shaking hands etc. He plays multiple tables at once, by placing bets on one, moving to another and doing the same. He does seem to like number 29. All wheels are rotated around the tables on a bi monthly basis. Haven't checked under special light source and haven't recorded spins when not there. Will get that sorted.

Yeah, someone has to get lucky once in a while, but when it is consistently the same person and on a very consistent basis you have to wonder if there is something that isn't being done or if there is some other factor involved. being a smaller casino this is a major concern for the performance of the floor.

I don't know how to formularize it, but in just about every casino game, even one with a huge negative expectation like roulette, there will be, statistically and in practice, SOMEONE who consistently whups the game's butt. We had an LOL who played keno every day, forty, fifty games in a row, and she was definitely WAY ahead lifetime--she just hit those six-spots far more often than she "should" have. It happens. Anomalies happen.

So if the management at your casino wants to drive away a good customer, they should bar this guy. And make themselves look pretty stupid in the process. If not, let him play; bring him free drinks and dancing girls.

Does he attract a following? Other bettors mimicking his bets?
If not, perhaps he is not such a winner as you think.

Probably using a well concieved and semi-hidden 1-1-3-1 system, which provides winning sessions in excess of 85%.

In the long, longterm however, it still makes the game unbeatable for the casino patron.

Guessing the fella is raking you over the coals with comps, correct?

There's a new-ish field called "Extreme Value Theory" which tries to quantify the probability of extreme events taking place, such as huge natural disasters, equity losses, etc. In short, over enough trials, someone or something has to be the most extreme. Like mkl said, the probability of SOMEONE winning a lot of money at roulette in your casino tends to 1.

You can quietly check your wheels, but if I was the casino, I would not sweat the money...

If he was cheating roulette in general, not colluding with a dealer or following a biased wheel, then he would move from casino to casino, right?
Even if he had invented a winning betting system, judged by our potentates of gambling to be impossible, he would still go from casino to casino, right?


So the casino should ask him if they can feature him in ads like you see the state lotteries do with people.

THIS PERSON HAS WON THOUSANDS OF DOLLARS EVERY DAY PLAYING ROULETTE AT OUR CASINO!

I swear it's a no brainer!

Meantime make sure he hasnt figured out how to cheat, sure, but they are wasting good publicity on this guy!

I like odiousgambit's idea of asking him to be in a promotion. Give him some serious comps for his time (after all he should have earned them by now).

Oh! the life of the guy living past 3 standard deviations!

On the right side that deviation of course.

I totally agree!

I thought the Over 85% system was to bet the last two numbers that are stamped on your parking ticket?

I would LOVE to be able to do this, but due to very strict government regulations regading casino advertising we can't.

Is this player now a multi-millionaire or was the whole thing just a wind-up?
