       | A couple of notes from my own experience in casino hacking fun:
       | 
       | 1. if they spot you singularly winning way too hard, they will
       | cut you off 2. if you can distribute the wins wide enough between
       | enough individuals you might get away with it
       | 
       | There ARE exploits and you can get away with them. People find
       | them pretty regularly and the ones who get away with it are
       | really organized.
       | 
       | My favorites over the past years: Weak PRNG in the Buffalo slot
       | machines [1], and people cleaning that, and the guy who figured
       | out an exploit in the game king brand video poker machines [2] -
       | One got away with it and the other didn't, it's worth being aware
       | of how.

         | You're assuming there's some basic aspect of "fairness" between

         | statistical odds is obvious of course, but most people assume
         | if someone _could_ somehow magically overcome the odds to win
         | consistently without breaking any rules they 'd be allowed to
         | do so. While that's a reasonable assumption, and one casinos
         | encourage, it's not the reality. A friend of mine who worked at
         | a high-level in casino management once told me, "There are many
         | documented rules but they are all governed by one unwritten
         | rule: the house must always win in the long-run."
         | 
         | The net effect is that if you start to win meaningful amounts
         | on a consistent basis, 'fairly' or not, the casino will simply
         | ban you from playing. Players misunderstand the relationship
         | between players and the house. Casinos however are under no
         | illusions. The role of players, in the aggregate and over time,
         | is _only_ to lose. If you don 't fulfill your role they won't
         | let you play. Beating the house in the long-run isn't possible
         | because casinos have no interest in losing.
         | 
         | Hypothetically, if you were somehow able to consistently win
         | meaningful amounts at casino gambling games through some kind
         | of fictional magic or psychic ability which could not be
         | countered, the only way you'd be able to monetize that ability
         | would be to either: 1) Win such small amounts you remain
         | unnoticed (probably less than a couple thousand dollars a
         | week), or 2) Continually travel the world seeking out new
         | casinos that haven't yet banned you. As the article shows,
         | casinos work together and word spreads quickly so neither
         | option is very appealing. If you had such magical powers it
         | would be dumb to monetize playing gambling games against
         | casinos. Much better to either play games against other players
         | or to pursue large open markets like stocks and commodities.
         | Even then you'd have to put up with constant investigations by
         | the SEC suspecting insider trading. You'd also need to
         | meticulously pay all taxes and comply with every regulation due
         | to all the attention you'd attract. It would probably be a good
         | idea to create your own 'explanation' by operating as a hedge
         | fund, investing in creating a large research department and
         | hire a bunch of quants to devise proprietary algorithms. Even
         | then, it would be smart to never "win" too much more than the
         | best legit hedge funds. If you're too much of an outlier for
         | too long, some people will take increasingly extreme measures
         | to determine your "secret."

             | Better than equal. Most Blackjack is -0.6% EV playing basic
             | strategy, but with counting, each true count is an extra
             | ~0.5% of EV, leading to big betting on high count hands
             | with EV of 1-3%. Of course, that's why casinos kick out
             | counters. They're literally "too good" at the game, and
             | they don't want that.

           | Anecdotally, I used to travel to a coastal city 650km away
           | every two weeks for around 5 years. My Saturday afternoons
           | during this time were usually free and I was bored. For two
           | months I spent those Saturday afternoons (til around
           | midnight) sitting in the casino noting the frequency of each
           | pie slice of the wheel on as many different roulette tables
           | that I could simultaneously view (between 6 and 8 at a time).
           | 
           | Divide the wheel into 5 pie slices (one will be a different
           | size from the rest) and make 5 columns on a small page - one
           | for each pie slice. Each time that slice "wins" (no matter
           | what the number is) simply make a checkmark in that column.
           | Over time this forms a histogram. If any one of those columns
           | is an outlier, then that wheel is biased.
           | 
           | I found _one_ biased wheel (casino had maybe 14 tables in
           | total?), which remained unfixed and remained biased for the
           | next 13 months or so, and I repeatedly just placed small bets
           | on all numbers in that slice that was biased.
           | 
           | I made a respectable amount of money (about 40k ZAR) over 13
           | months.
           | 
           | I have no illusions that had I been placing maximum bets on
           | each spin, I'd have been escorted out of the casino after the

       | "Breaking Vegas" covers another way to beat roulette but without
       | requiring computers or communications devices in the casino or
       | timing anything. Archive.org has a copy of that episode [1].
       | 
       | A family went to casinos around Europe and observed the roulette
       | wheels, keeping extensive records on where the ball landed. They
       | were not covert about it. They'd just openly write down the
       | results.
       | 
       | You might think casinos would not allow that, but actually they
       | love people who do things like that. A person taking notes is a
       | person who thinks they can invent a system to beat the casino,
       | and those people often lose a lot of money before giving up.
       | 
       | The family took all that data and analyzed it to find wheels that
       | had slight consistent biases that were big enough that bets based
       | on them would come out ahead long term. They then went around
       | making those bets and won long term.
       | 
       | The family members had spent so much time looking at wheels that
       | they could recognize individual wheels by things like scratches
       | and discolorations and other ordinary visible wear and tear, so
       | even if a casino moved a wheel the family would recognize it and
       | know which bets to place.
       | 
       | There are a couple other "Breaking Vegas" episodes I remember as
       | standing out.
       | 
       | "Ultimate Cheat" [2] is about another way to win at roulette, but
       | this one involved a team cheating on the bets using a twist on an
       | old cheating method.
       | 
       | There's an old way to cheat on bets where you place small bets
       | that consist of a stack of minimal value chips. You adjust the
       | stack so that the croupier cannot actually see the bottom chip.
       | You and your teammates all do this.
       | 
       | If one the bets wins you try to use sleight of hand to replace
       | the stack with a stack that consists of minimal value chips
       | except for a high value bottom chip, still arranged so the bottom
       | chip is not visible to the croupier. Your teammates can help by
       | trying to distract the croupier so your sleight of hand won't be
       | spotted.
       | 
       | When the croupier goes to your winning bet you point out the
       | amount is wrong and point out the high value chip in the stack
       | that the croupier missed.
       | 
       | Casinos are on to that, and if they suspect at all that you are
       | doing it before paying out they will go to the security tapes to
       | make sure no one tried any sleight of hand on the winning stack.
       | 
       | The team in this episode realized they could work this the other
       | way. Instead of trying to retroactively raise the value of
       | winning bets they could retroactively lower the value of losing
       | bets.
       | 
       | So now the first stack is a stack of low value chips with a high
       | value chip on the bottom with the stack askew to hide the high
       | value chip. If the bet wins no sleight of hand is needed. The
       | high value chip is already in place. If the bet loses that's when
       | they try sleight of hand to switch it for a stack with all low
       | chips. That's easier than switching a winning stack because the
       | croupier is paying attention to the winners.
       | 
       | If the casino goes to the tape after a win no problem. The tape
       | will show no tampering because there was none.
       | 
       | The casino security people knew the team was up to something for
       | quite a while and were scrutinizing every one of their wins and
       | getting really annoyed and frustrated that they couldn't figure
       | out what the heck was going on.
       | 
       | "Counterfeit King" [3] was about counterfeit casino tokens.
       | Manufacturers incorporate a variety of anti-counterfeiting
       | measures in their token designs, but Louis Colavecchio was able
       | to match them all. The only reason anyone knew there was
       | counterfeiting going on was casinos were finding themselves
       | gaining token. No one, including the token manufacturers, were
       | able to figure out which tokens were genuine and which were
       | Colavecchio's.
