Let’s be clear about what a ‘System’ is. Most ‘Systems’ are a series of bets designed to give you an advantage. None of these can ever work. Stated formally: “Any number of negative expectation bets, when summed together can never yield a positive expectation.” If you take this to heart, you’ll never have to waste time listening to someone explain how you can win if you always double up on losses (Martingale), or have some other wacky, complicated scheme. And there are some really complicated ones, like the D’Alembert Cancellation system, etc.
However, there ARE ways to beat many casino games. It’s just not true that if the casino offers a game there can be NO way to beat it or they’d be broke. What is true is that there can be no easy way to beat these games. It’s always going to involve some work, and the casinos count on the fact that the average gambler is too ignorant and lazy to learn.
Most people understand that you can beat blackjack by card counting. There are pros out there making six figure salaries from card counting, and the casinos are still standing. Why? Because for every guy who beats the casino card counting, there are ten more who learn just enough to be dangerous, and go in and bet way more money than they should because they think they have the edge when they don’t. And the casinos employ security to make sure the really big money card counters have a very tough time of it and don’t stay long.
Baccarat has been beaten by some card counting teams. Traditional counting techniques are virtually useless, but there are some highly specialized and very difficult counting systems that can return some pretty good value.
Roulette has been beaten by clockers and in the old days, by some computer hackers (read “The Eudaemonic Pie” for a description of a team of guys who used a computer to beat the wheel).
The sports book can be beaten, because the line generally moves with the public, and the public is often wrong. So if you’re a good handicapper, you can make money betting sports. But you’d better be VERY good, with sound mathematical principles behind you.
Poker can be beaten because you’re not playing against the house, but against other players. Their mistakes, minus the house rake, equals your profit. An excellent mid-limit poker player can make up to 2 big bets per hour playing poker. So if the game is 10-20 holdem, they can make as much as $40/hr.
Then there are the casino mistakes. Sometimes they screw up the odds calculations and offer a game that can be beaten. These games never last long, but if you can get to them before the rest of the sharks do, you can make a killing.
A couple of examples: David Sklansky, a famous gambling expert, beat the Stardust up pretty badly because they screwed up the odds calculations for a parlay card they offered in the sports book. Sklansky did the math and realized that if you bet every possible combination on the card, you were guaranteed a profit. Specifically, there were 1024 possible combinations, and if you put a dollar on every one the card would return $1660. He made out like a bandit, but the card only lasted a week at the Stardust.
Another famous episode happened at the Klondike, a small casino with only about 15 blackjack tables. The pit manager there came up with what he thought was a GREAT new game: He even had the name copyrighted, and they planned to market it to other casinos. It was called “Free Ride Blackjack”. In Free Ride Blackjack, every time you got a blackjack you’d get a little disk called a ‘lammer’, which would entitle you to surrender a hand in the future and get all your money back. They thought this wouldn’t change the math very much, but in fact it gave the basic strategy player a 2% advantage over the house. Word got out amongst the pros, who flew into town and filled every seat in the place playing basic strategy (no card counting), and flat betting the table maximim ($500) on every hand.
It took 12 hours for the Klondike to throw in the towel, but not before they actually had to use the general staff as chip runners, going around to the tables and buying back the chips from the players for cash because the casino didn’t have any left.
So you CAN beat Vegas, but it requires brains, sweat, discipline, and a ton of work.
