    Surprised they're so open about what they do!

    It's one thing to say you do something, it's an entirely different thing to say how you do it. For example, saying that you have an RFID chip in every casino chip is one thing. Having a monitoring system that can quickly and automatically identify a RFID position and movement anomaly among millions of active casino chips is something else.

      One of the major points of the RFID in the chip is that when a chip is played in a slot machine or some such, they can check if there is a chip there and if it's valid. If it's not, the machine can automatically alert the casio at that moment that there is someone using fraudulent chips and arest the person. Same could be done on a table when the dealer collects chips. It's not neccessisarily about finding out who is doing what when and their patters (although they want that), it's about finding fraud faster.
      • I've never seen a slot machine that accepted casino chips. They take coins.
    • Also, no harm in letting everyone know what you can do.

      "We know everything about you."

      In general, I'm sure the casinos would consider it preferable to advoid cheating, than to catch cheating. In the same way, police will often patrol an area that might be more likely to have crime (like a concert) BEFORE any crime is done.

    There was a special about a month ago on Discover or one of those channels about this guy who made his own tokens for use in casinos and how he went about doing it, including having to figure out the right metal combinations, making the dies, getting giant press machines to form them, and everything. It was facinating. The way they finally caught him was the counts of tokens would come out high (they should have 100 $50 tokens at the end of the day, they'd have 120). Then from that they were able to go find him (eventually spotted him using them in a slot machine, and when the machine didn't like a token he put in, he just kept going where anyone else would complain LOUDLY about it).

      If a game is not a game of chance, but a game of skill, then the law does not allow casinos to host that game. So on one hand, casinos want to ban card counters, but on the other hand they don't want to admit that skillfull players can play better than players relying purly on luck.

      Basically, they get to throw you out if they catch you counting because it's a private establishment. They can throw you out if they don't like the color of your shirt.

      Honestly, I agree with you: it's dumb to throw out players just because they can play better than you allow yourself to. (The percentage comes mostly from the fact that the dealer must hit on 16 and soft 17 no matter what the count looks like. A smart dealer would have a huge advantage, with the player having a chance to bust first, but they don't want to make it a skill vs. skill contest.)

      In Atlantic City, it's actually getting harder to find a straight 21 game. They have a lot of variants of it, and although I haven't done the math I bet they eliminate your percentage in the game. Your percentage is small and it's not that hard to eliminate it with a few rule changes. But I guess the Vegas houses feel strongly about the traditional game.

      Still, it would be a lot cheaper to change the game than to try to catch people based on what's in their heads. (Or in their shoes, if they're using an illegal computer. At least there they're trying to restrict the game to skill, including memory, although again a rules change could eliminate the advantage of having a computer.)

      I suspect that they like the fact that people know that there's a percentage to the player in 21, even though most people don't know how to get it. And unless you're playing on a team it's hard to make money fast at it. (If you can play well enough to get a 1% advantage, you win an average of $1 per hand at the $100 table, which comes out to perhaps $30 an hour. Real money, certainly, but a lot of work for it.)

      So if there are 6 players at the table and 5 of them are losing because they don't play the game very well, and they can catch you if you're making the big money playing on a team, it may still be to their advantage to leave the rules as they are. I've never heard of them messing with a small-time card counter, even though it's obvious they're counting.

      Sounds dumb to me. There's a lot more vigorous cheating going on (stealing chips when people aren't looking, for example) that's easier to catch.

      No, they aren't. Sure, if you play Keno, your odds suck. But if you play basic strategy (not hard to learn) and find a decent Blackjack game (NOT 5:6, etc.), the house edge is frequently below 0.5%.

      And cheating is cheating. If you don't like the house edge, don't play. Stealing chips from a casino is exactly the same thing as stealing real money.

      Remember, the cameras aren't just there to prevent you from cheating - they are also there to prevent the house from cheating. The NGC is, thankfully, a bunch of hard-asses who will pull licenses if the casinos don't play on the straight and level.

      In Vegas, the games are fair. Sure, the house has the edge, but the deck isn't stacked and the slots really are random.

      Playing BS Blackjack at $10 a hand, with a decent game (house edge 0.5%) costs only $.05 a hand. At 100 hands an hour, that works out to $5 an hour. It's every bit as cheap as a movie, and you get free drinks. Moreover, if you play for a few hours, you can probably get a comp for the buffet.

      Know how much you're willing to lose (and stick to it), know which games to play (and what the house edge is), know the rules, know the basic strategy, and have fun.

      It's not really known how often collusion takes place on internet poker sites. Most reputable sites at least claim to monitor playing habits and look for patterns that might indicate cheating. But who really knows how often they catch people. It certainly seems like it would be in their best interest to catch cheaters. Although stricting speaking the cheats don't steal money from them since they still get a rake of every pot, if a site has a bad reputation players will be less likely to use their site and switch to a more reliable one.

      They can monitor to see how often specific players play at the same table and observe the betting patterns of those players. One technique colluders will use is to gang up against a player who is going all in to increase the odds that player will lose the hand. If player X pushes all his chips in with pocket aces and 3 colluding players call with decent hands there is a good chance the aces will not hold up and one of the colluders will win the pot.

      There have also been accusations of poker sites doing the cheating. By altering the odds, they can generate bigger pots and therefore bigger rakes. Take a simple example. Deal one player pocket aces and another player pocket kings. Both players are likely to push a lot of chips with those hands and make a big pot. Drop a king on the flop to give one player a set and you're really going to see sparks. The bigger the pot, the higher the rake the house gets. I'm not saying this actually occurs at most poker sites, but it's an interesting thought experiment.

      Uh, no you can't do that. Gaming regs here prevent casinos from doing that. If you advertise a 99% payout on a bank of slots, those slots HAVE to have a 99% payout (mind you, it's over the lifetime of the machine).

      Payout schemes are locked in each machine in the presence of a gaming control agent. They have ways to tell if a machine has been tampered with. Gaming in Vegas is quite on the level- people just forget that a casino won't engage in a game of chance unless it is favored to win.

      And there's plenty of homeless people on the streets here in Vegas, so come on down with your roll of cash...

      No, they can't. First of all that's illegal, and is tracked. Second the machines simply aren't built to allow that. Slot machine have a locked "theoretical hold" value which is the theoretical long term amount that the machine will retain as a percentage of turnover. It is fixed, tracked and cannot be changed - certainly not at the click of the mouse.

      What a casino can and will do is lay out the machines on the floor with theoretical hold as a consideration. That is, they will endeavour to put a bank of relatively low hold nickel or dime machines near the entrance (not at the entrance mind you, the machine right at the front will be dollar machines or the like: they want casual gamblers wandering by to play the high stake slots) so you get to hear the sound of people winning. The rest of the floor layout is just as carefully designed, taking into account the theoretical hold, popularity of the game type, denomination of the game, quality of the floor space (harder to quantify), and so on to maximise profit. I used to work in the R&D department for a software company that helped casinos do this more effectively, so believe me, I know how exacting they are.

    back when i worked in a casino i had this guy buy in for a couple hundred bucks on a crap game. i was handing the money into the box person and was joking that the money looked fake. he thought i was serious and so looked at it a little more then i had. turns out it was counterfeit and security pulled the guy off the game. turns out after talking to him and running back the tape, he was passed the bogus money from our our cash cage!

    the RFID in the chips is a good idea. we once had some bogus 100's come in one afternoon and everyone knew about them but i was still finding them a day later in "clean" banks. if they were all RFID'd you could scan a whole bank and see if it matches what you have down on paper as the proper amount. short a few 100 then there must be some bogus chips in there someplace better take a good long look.

    as far as the cheating goes. the only place it's even worth trying is on a crap game with two of the dealers in on it. when the stick person is watching the dealer who's in on it, that's when you pass off a stack of chips. nothing too high for you might call attention, maybe $100.00.you only do a few hundred a night on a BUSY game other wise they will spot you quick, greed is bad. craps is a very verbal game, unlike BJ where everything is done with hand gestures and easy for servailance to watch. in the years that i dealt craps never did servailance call down and ask about a payout we made or about any of the action on the game. it moves too fast and is too verbal for them to know what's going on. if you have a busy game and no box person or floor watching, you could very easy hand off a "payout" that was not legit and nobody would ask or care. there were many many times where i would book a bet verbaly without seeing the actual money on the table and the dice would roll and the person would either win or lose and they would payup or i'd pay them and there was NO money any where to be seen before that moment for the camera. which is why you are always nice to the crap dealer in front of you and watch what you joke around about, i've booked bets that people were joking about, at that point they pay up or they get escorted out of the casino. that was always my favorite way to get rid of people that pissed me off.

    The odd aren't just stacked in the casinos favor, they also throw out players who win too much. Casinos use the surveillance systems and facial ID systems to detect and bar players who are card counters. Card counters are not cheaters, they are people who are really good at math who carefully observe what cards have been played and place bets accordingly--just as expert poker players do consciously or unconsciously. Cardcounting can give these blackjack players an extremely small edge. But casinos don't like to lose even to legitimate players. Rather than make adjustments to the game of blackjack, casinos throw winning cardcounters out and pass a blacklist of photos to other casinos around the country. This unethical practice of baring players merely for winning should be illegal, but the gambling influenced laws in places like Las Vegas fully support it. Casinos hold out the promise that you can win if you are good, but balk at actually letting you play if you are really good. Using high tech security to bar non-cheating players for winning is unethical and should be banned. The article should be condemned for giving the false impression that casino security is only used to catch cheaters.

    Under law it's illegal to tamper with slot machines, use slugs, play with tampered cards, etc. It's also quasi-illegal to do things like posting, which means changing your bet after the game has started. There are tons of gambler cheats.

    The most common "cheat" which isn't a cheat, however, is card counting in Black Jack. Casinos have been known to harass and eject gamblers who are expert card counters. The process is not illegal but they are labelled as cheats anyway. Card counting is little more than being really good at math and concentration and coming up with a consistent pattern. Casinos don't appreciate it because most games have an automatic "profit margin." Roulette, for example, has lots of ways to bet, but if you were to down the same amount of money on every number, you'd end up with winnings of only 80-90% of what you initially put down, essentially losing money. Mathematically they are designed to win unless you cheat.

    Blackjack is not the same. You can beat blackjack because the odds say if you play things right, you can come out on top even in the long run. That's why so many organizations have popped up in the past few decades running "black jack" companies. They are made up of math wizzes who train at card counting.

    Then the casinos find them, repeatedly showing up, figure out they are counting cards, and then eject them from the casino. It's completely legal so they can't arrest you, but because it's a private company they can refuse your business and ban you from their business, and future excursions to their casino would be considered trespassing.

    It's pretty scummy, though I must say it's an improvement over getting your knee caps shot off for being a good poker player, like in the good old mob days.
    • Funny TFA insists the house always wins while admitting they are looking for counters.

      One correction though: no need to be a math whiz to win at Blackjack. And in Canada, it's illegal for the Casino to eject you for counting, although they can take some countermeasures.

    A few of us took a couple days off in vegas this weekend. After about ten hours at the tables over friday and saturday, I got a tap on the shoulder...

    Three men in dark suits introduced themselves and explained that I was welcome to play any other game in the casino, but I am not allowed to play blackjack anymore.

    Ah well, I guess my blackjack days are over. I was actually down a bit for the day when they booted me, but I made +$32k over five trips to vegas in the past two years or so.

    • Card counting at blackjack is actually pretty easy to pick up, and you don't need expensive high tech systems to do it. You just need staff who know what the signs are and are reasonably vigilant. It takes some time to really make a lot of cash at card counting, and in general casinos are entirely capable of picking up on it quickly enough that it really makes very little difference to them. There are some interestign and elaborate schemes I've seen that can actually get past these basic measures but they r

    among the millions of stupid players

    At its crudest level this would stop the appearance of counterfeit chips and would also catch players trying to sneak an extra chip onto their stake upon winning.

    You mean these readers are good enough to read the RFID's of chips stacked directly on top of each other? There must be some sort of random delay to prevent collisions. Be interesting to know more about the technology of reading a lot of simultaneous RFID chips in close proximity to each other.

    a player laying $5 bets while sitting with $100,000 of chips in his or her pocket. This is certainly no cause for concern in its own right but such behaviour would in the past have caught notorious card counters waiting for the odds to fall in their favour or getting their eye in and honing a system.

    Oh, card counters are nororious now? Last time I checked, card counting is not illegal. Casinos will certainly try to keep you from doing it, but it is a skill for an Advantage Player, and not a cheat. It's only PR that tries to tell you otherwise, but the bias in this article is already apparent.

    And btw, since when are casinos entitled to know the contents of your pockets? Time to get out the aluminum foil for the pockets.

    Subsequent players, one replacing the other at a table, whose bets vary greatly in size but whose chips originate from the same batch could also be identified as potential partners in a system.

    I'd say any cheat team will quickly learn to acquire their checks (casino-speak for chips) separately soon enough.

    Carol Pride, CIO of Caesars Palace, told silicon.com that many casinos favour chips and playing cards marked around the edges with invisible inks and barcodes, enabling optical monitoring of their movement and authenticity.

    Great! The casino's are marking my decks for me now. Well, if a tv camera can see it, then there will be a way for me to see it too. It's not an invisible ink if they can read it.

    Say what they want, but there are very few people serving jail time for cheating a casino in this country.

  • Back in '99-00 I was spending a lot of time at Las Vegas casinos. At the peak, I was visiting every other weekend, and I was card counting. Unlike the sensational stories popularized in the media, I was not a "big time" gambler. I was not doing this for a living, and I wasn't do it to strike it rich; I was doing it for fun.

    Typically, I'd go out there with $500, find a place with 2 deck blackjack (single deck in true form doesn't exist... the places that advertise it typically cut the deck so deep that you'll only get two hands out of each shuffle), and spend 40-50 hours over the weekend playing. At lower limit tables, even playing perfectly, that doesn't amount to much. On average, with that $500 stake, I'd live with about $700 in my pocket, up $200 for the weekend. This works out to about $5 an hour, less then minimum wage.

    Sometimes, if I was lucky, I'd come out with more, but I didn't always win. There were times where I'd leave with 5 crisp $100 in my pocket and return home with nothing but a few good stories.

    My favorite experience was at the Excalibur. One night, while playing low limit blackjack an older man sat down at my table. He was flanked on both sides by attractive women nearly half his age, and he was really, really drunk. He pulled a giant wad from his pocket of tightly rolled $100 bills, peeled off a few of them and laid them on the table. The dealer picked them up and said "Changing 300", to which this man yelled "no, damnit I don't want any chips that's my bet!" "money plays".

    He lost. He did it again. He lost. When he would win, he'd throw his winnings back on the table and give them back to the casino. Chips, he explained loudly, were "unlucky". His play was horrible; he'd hit a 16 with a 5 showing, double down on an 8 against an Ace. Meanwhile, I just sat there quietly plunking down my $5 bets, occasionally raising them to $10 or $15 when the count was good. This guy was attracting so much attention from the casino staff that my small potato attempt at card counting (which wasn't on that night anyway) went by unnoticed.

    At one point, he put $800 down on the table. This was a min $5, max bet $500. "I'm sorry sir, but the maximum bet here is $500". Almost instantly, the pit boss swooped down said "This man can bet as much money as he likes". Of course; this man was a drunken idiot trying to impress the those two woman (I don't know if they were prostitutes or what) by loosing as much money as he could. During the 45 minutes or so he was there, he lost about $20 grand. After that fat roll of $100s were gone, he got up with the help of his lady friends and stumbled out of the casino with a big grin on his face.

    I pretty much stopped playing seriously after three losing trips in a row. Now when I get to Nevada I might spend a few hours at the tables, but the all night sessions are a thing of the past. To this day, I still don't consider myself a "cheater"
