The Experiment Proving that Betting Systems Are Useless

A man in a tuxedo with a bow tie makes a big bet

In multiple articles, reviews, and comments published on Casinoz, we have repeatedly claimed that betting systems (not to be confused with optimal strategies) do not lower the house edge in online casino games.

The conclusion is obvious:

Betting systems do not help you beat the casino.

We have provided indisputable facts, offered articles by famous mathematicians, and engaged in open debate with software vendors. In short, we made every effort to present the truth to you.

Nevertheless, some of our readers remain unconvinced. Many people still believe that there is a betting system that can help them win at roulette or pokies. We will not retreat and will continue to struggle with the illusions.

This article will tell you about the practical experiment conducted by Michael Shackleford, the owner of Wizard of Odds, one of the most influential English-language web resources about casinos and gambling. If you still believe in the efficacy of betting systems, be sure to keep reading.

Michael Shackleford's Challenge

Between 1999 and 2005, Michael challenged all betting system supporters by offering them a bet. He bet $20,000 against $2,000 that any system proposed by the reader will not be effective within one billion hands, spins, rolls dice, etc. To check it, he suggested using a computer simulation.

Naturally, many approached him during this time, but nobody agreed to participate in the bet. The reasons for refusal were different.

  • Some did not trust Shackleford (or tried to justify this), although he was not opposed to the involvement of third parties, which would ensure fairness.
  • Others doubted that the simulator would give the correct results (too weak " excuse ").
  • Some people tried to cheat Michael, convincing him to play by the rules that give a mathematical advantage to the client.

It seemed that practical tests would never happen...

The First Competitor

But in 2004, Daniel Rainsong dared to challenge Shackleford. Moreover, he was so confident that he offered to double the bet: $40,000 of Michael against his $4,000. The owner of Wizard of Odds agreed.

After a lengthy exchange of emails, participants met in person to discuss the details and conduct the experiment. Daniel set a condition: if he won, Michael would tell about their contest on his website and recommend Rainsong's book. Shackleford agreed.

Then they signed a notarized contract. The entire amount of the bet was transferred to an independent judge. It was a professional card counter with a degree in statistics (his name was not revealed).


For the experiment, they chose blackjack with the following rules :

  • The game is played with two decks.
  • The dealer stands on "soft 17."
  • Split can be done up to four times.
  • Double after split is allowed.
  • No resplitting aces.
  • One card is dealt to split aces.
  • No surrender is allowed.
  • The dealer cuts a quarter of the cards in the shoe.
  • There are no unusual rules.

In such conditions, the house edge is 0.26% if the player does not count cards or use other professional techniques.

Daniel Rainsong's procedure was unrelated to card counting and did not depend on the depth of cutting decks in the shoe. Michael did not want to disclose the details, so he did not share them with readers.

Practical experiment proving the uselessness of betting systems

Daniel said he used the latest scientific discoveries in genetics to develop the technique. This system allowed him to win more than eight thousand in thirty-three thousand hands at a starting bet of one dollar.

To explain the method, Rainsong attempted to pressure the proposal to give him only half of the forty thousand without calculation. But, of course, Shackleford refused that "tempting" offer.

The Experiment on Betting Systems

The game was held in October 2004. It took about fourteen hours for the simulator to generate one billion hands. The opponents decided to track the outcomes. They agreed to stop the experiment if the resulting data was apparent.

At first, the system won, but it shifted to the read after 170,000 game rounds. Then, the result worsened. After ten million deals, it became clear that the method was a failure. Rainsong admitted his defeat.

The results were as follows:

  • Number of deals: 10,000,000
  • Total bet amount: 10,357,394
  • Final bankroll -30,381.5
  • The final hand with a positive bankroll: 168,621
  • Fixed house edge: 0.2933%

As you can see, the numbers speak for themselves. If the experiment continued until the end (i.e., up to a billion hands), the casino advantage would likely have decreased and approached the 0.26% level, but it would not disappear entirely.

The author of this technique continues to sell his book on how to win at the casino on eBay and even asks Shackleford to recommend it to his readers. And it does not amaze us because fools will buy this product and try to apply it in practice. Some people are surprisingly persistent in their pursuit of realizing impossible dreams.

The End

Although no one else wanted to participate in the experiment, many wrote to Michael, but no one agreed to bet. In 2005, Shackleford announced that he would no longer accept challengers.

Conclusion

We do not want our readers to make wrong conclusions. The fact that Rainsong's system was in the black for the first 170,000 hands does not mean that players can use it to beat the casino and need to quit at the right moment.

It is only a matter of luck. If you repeat the experience, you might start losing from the very first hand. And the longer you play, the closer your results will be to the theoretical house edge.

You can have an advantage over the casino when it comes to blackjack. To do this, find the offline casino offering the best rules, play by the optimal strategy, count cards, and use other professional tricks. But in practice, it is much more complicated than in theory. And at online casinos, it is impossible.

We hope the story about this awesome experiment convinced you that betting systems would help you beat the casino. However, studying optimal strategies for games such as blackjack, video poker, and table poker can be beneficial. They help to achieve better results.

Additionally, Casinoz recommends reading an article by an American professor of mathematics on betting systems and the house edge.

Frequently asked Questions

🎰 Why do people believe betting systems work?

Many people are drawn to betting systems because they offer a seemingly logical and structured approach to a game of chance. They provide a sense of control and a mathematical framework, leading players to believe they can outsmart the inherent randomness of casino games. The human mind often seeks patterns and predictability, and these systems tap into that desire, offering a false promise of guaranteed wins or minimized losses through disciplined play. The allure is in the idea that one can beat the house through intellect or strategy rather than simply luck.

💰 Are there any betting systems that genuinely work?

No, there are no betting systems that can genuinely alter the fundamental odds of a casino game or guarantee a profit in the long run. Every casino game is designed with a built-in house edge, which ensures that over a large number of plays, the casino will always come out ahead. While a betting system might appear to work for a short period due to random fluctuations in outcomes, it cannot overcome this mathematical advantage. Whether you double your bet after a loss or adjust it based on previous outcomes, the probability of winning or losing on any given play remains independent and unchanged, rendering all systems ultimately ineffective against the house's inherent edge.

❔ What is the "house edge" and how does it relate to betting systems?

The house edge is the mathematical advantage that a casino has over players in any given game. It's expressed as a percentage and represents the average profit the casino expects to make from each bet placed over the long run. For example, if a game has a 2% house edge, the casino expects to keep 2 cents for every dollar wagered over time. Betting systems cannot circumvent or reduce this house edge. They merely dictate how you place your bets, not the underlying probabilities of the game. Even with a sophisticated system, the casino's inherent advantage remains constant, ensuring that over an extended period of play, you will inevitably lose money equal to the house edge multiplied by your total wagers.

🤑 Why do some people claim to have success with betting systems?

Claims of success with betting systems often stem from short-term luck and cognitive biases. When a player experiences a winning streak while using a system, they may attribute their success to the system itself rather than acknowledging the role of chance. This is a common psychological phenomenon where people selectively remember outcomes that confirm their beliefs and disregard those that contradict them. Additionally, some individuals may only focus on their peak winnings, forgetting or downplaying their subsequent losses that eventually lead to a net negative outcome. The inherent randomness of gambling means that even with a "losing" system, a player can experience temporary positive variance, which can be mistakenly interpreted as the system's effectiveness.

💲 Does managing your bankroll make a betting system effective?

While responsible bankroll management is crucial for any gambler to avoid significant losses and extend their playing time, it does not magically transform a flawed betting system into an effective one. Bankroll management is about setting limits on how much you are willing to risk and sticking to those limits, regardless of whether you are winning or losing. It's a strategy for financial discipline, not for altering game probabilities. A betting system, on the other hand, attempts to dictate the size or pattern of your wagers to influence outcomes. Even with perfect bankroll management, if you are employing a system that doesn't overcome the house edge, you will still, in the long run, lose money at the rate determined by that edge. Bankroll management helps you control how much you lose, not whether you lose.

🎲 If betting systems don't work, what's the best approach to casino gambling?

The most realistic approach to casino gambling, given that no system can guarantee wins, is to view it as a form of entertainment with an associated cost. Acknowledging the house edge is paramount. The best strategy is to play games you enjoy, understand their rules and odds, and gamble responsibly within a predetermined budget you are comfortable losing. Focus on the experience and the thrill rather than expecting to make a profit. Some players might find value in learning basic strategy for games like blackjack, which can reduce the house edge to its lowest possible point, but even then, it doesn't eliminate it. Ultimately, accepting the entertainment value and setting strict limits is the most sensible and sustainable way to approach casino gambling.
