A High-tech Wheel of Fortune
tcp writes "The BBC is reporting that the London police have detained three people, for allegedly beating the roulette wheel at a London casino. Using a cell phone, a computer and a laser scanner, they were able to predict where the roulette ball would land, winning more than 1.5 million dollars in the process. This technique was not new, and as I recall was the plot of a movie once. The suspects have not been charged yet. The UK has been behind in bringing their gambling laws to deal with new hi-tech threats unlike the US and Las Vegas."
I've seen computerized card counters - but being able to read a roulette wheel, that's something...
:)
some people who would consider themselves professionals do the same thing by eye - make a guesstimate based on when the roulette employee releases the ball - but to do it with computers - well, that's just wrong
but if it ain't illegal, it'll be hard to prosecute - it's like counting cards...not illegal, but you'll get your butt booted from the casino pronto -

Randomness is really sometimes just a proxy for "too complex to be understood". Afterall, in any form of mixing bin, all of the balls inside do have to obey the laws of physics. If you knew the starting positions and details about all of the activities that are going on in the bin, you could possibly solve for which ball is going to be the one selected.
That's why it's essential that some details of the mixing situation should not be disclosed to the public while betting is still going on. I think what makes most daily blower-bin based lotto games unpredictible is the fact that the exact to-the-nanosecond time at which the bin is opened is being determined by a presenter who is also responsible for talking at the same time. Therefore, they can't possibly have enough control of their hands know what exactly their influence on the outcome is going to do. Since nobody else can really predict down to the fraction of a second what the presenter is going to do, everybody's on a level playing field.
I think the ultimate solution to this roulette wheel issue will be to call a stop to betting before the ball and wheel are put into motion. Therefore, by the time the information needed to determine the result of this spin is available, it will be too late to act upon it.
Ball Control
Although no casino will admit to its existence and very few dealers will nod in acknowledgement, this method is very powerful and easy to disguise. One cannot deny that a roulette event is heavily influenced by a human dealer. After all, it is the dealer who kicks up the rotor speed and launches the little white ball isn't it? These actions definitely affect where the ball will land. And after years of repeatedly spinning, the dealer develops what athletes call "muscle memory" or a consistent delivery system. I will admit it to you right here, as someone who has dealt the game of roulette, SOME DEALERS CAN CONSCIOUSLY INFLUENCE THE RESULT OF THE GAME. There, I said it! I know that deflectors may knock a ball off its original course or the ball may spatter when it crosses onto the rotor and hits a pocket fret, but even if a skilled dealer could navigate around the heavily bet sectors on the wheel only 10% of the time, the casino's edge would be 100% for those spins! The house's edge would then be [(9) x 5.26% + (1) x 100.00%] all divided by 10. This averages out to a whooping 14.73 % edge! To further add to this dilemma, there is no way to prove that the dealer is trying to cheat you, unless you can read minds! My general observations have led me to believe that "male" roulette dealers are more territorial. If you begin to win steadily at their tables, they feel challenged and may spin against you... that is unless you're a shapely female wearing a low-cut dress. I've also seen first-generation immigrants working as dealers, who are staunchly loyal to their new employers. If the issue of ball control troubles you, you can simply wait for the dealer to spin before placing your bets. You might actually turn this technique in your favor. If you recognize a skillful dealer and can build a rapport with him or her, you may be able to exploit their ability. One way to induce a dealer into hitting your number is to bet a sector or continuous section on the rotor of say, five pockets. Place a toke out for the dealer on the number situated at the sector's center. The dealers seem to appreciate a crack at collecting 35 times their original toke if they exhibit some control. If they miss your center number by one or two pockets, then you still win on the neighbors contained in that sector.
Source
The greatest hack I ever pulled off involved an online casino. The casino used a Java applet for the gaming - everything from Blackjack to slot machines. Bored on a weeknight, I downloaded the Java applet (JAR file) to my computer and used a java decompiler to restore the original source code. Unfortunately, the code was obfuscated, but what I found next surprises me to this day. The java applet was using the client machine to generate the random numbers used in many of the games, namely the slot machine. I modified the code slightly to increase the chances of winning on the slot machine and then recompiled the code. There was a small problem, however. The code was written so that a response from the client to the server was sent indicating how much was bet, the payout and the winning combination (or hand). Thus, it was possible for them to statistically analyze my gamblings and calculate that I was winning more than I should have been. So instead of winning of the slot machine, I would win at Blackjack by modifying the code to display on screen what the dealer's cards were, and what the next card in the deck was. Thus, it was possible for me to decide on when to hit and when to stand. I will not tell you how much I won but I will tell you that I have never been caught.
As a roulette dealer myself, I can assure you that this is a conceivable position but not an agreeable one. Spinning the wheel faster does cause the frets to have a greater influence on the ball, but its still statistically going to stick to that section.
As well, as the article notes, PLAYERS don't like it! There are only so many rule changes you can make in the interest of cheat reductions before the legitimate players get fed up and leave. (One of these is disallowing blackjack players to increase the number of hands they play mid-shoe). As an aside, in the Province of Alberta, casino dealers are to stop betting two ball revolutions BEFORE THE DROP, not after the spin commences. As in many gambling areas, the regulations must be changed: the casino can't just create rules (even sensible ones) out of the blue.
For this reason, speeding up the wheel and reducing bet times are not good ideas. It will prevent cheating, because the legitimate players will stop playing and the game will be shut down!
The best way to prevent wheel tracking I've found is just to constantly (every spin) change the speed of the wheel and the ball. I like to let the wheel slow and then push it with the ball just before I spin. This would require these cheats to constantly re-compute, increasing the likelihood of detection.
That's the point really. There is a way to predict the outcome. Like a lot of games, it is not a game of pure skill, it has an element of chance and an element of skill in the form of predicting where the ball will land. Just like blackjack is a game of chance and skill. The skill comes in when you try to predict what cards are going to be dealt based on statistics and your knowledge of what cards have been dealt so far. Of course, the casinos consider people who are too good at "counting cards" to be cheaters as well.
The problem here is that the argument that you cannot use technological devices to help you in gambling is a slippery slope argument. I've never heard of a casino banning anyone for glasses or contacts, even if they help people see better and therefore enhance their natural gambling skills. What about future visual aids. Lets say you have a low resolution artificial retina for blind which cannot see as well or in the same way as a normal retina and makes up for it by, for example, using a computer to track motion and plotting courses for objects in Heads Up Display? Or how about if it allows the user to rewind their vision to specific bookmarks, allowing them to supplement their memory (helpful in remember what cards have already been dealt, for example). Are the disabled going to be banned from future casinos?
All this is really beyond the point in my opinion. Random redistribution of wealth at casions is stupid. Redistribution of wealth based on exceptional skill at gambling is considered cheating by the casinos. The government, when they allow private gambling to interfere on their own gambling monopoly, seem to agree with the casinos in these matters. So, the end result is that, on the whole, the only people who actually win at casinos are the odd successful gambler, the cheaters who do not get caught, and the casinos themselves. In other words, casinos are dumb. I guess I hold the view that people should be allowed to gamble if they want to, but I think they are stupid to do so.
