Casino Games and Mathematics: Part Three
Summary
A year after his initial findings, Thorp published a book that outlined a winning strategy in simple and clear terms. This publication not only increased the number of gamblers seeking to profit from casinos but also enlightened casino owners about the effectiveness of Thorp's strategy.
Article
A year later, Thorp published a book that clearly detailed the rules for creating a winning strategy, making it accessible even to those with basic understanding. The book led to a surge of individuals eager to profit at the expense of casino owners while also highlighting the strategy’s effectiveness to the owners.
The primary realization for casinos was the necessity to introduce a new rule: thorough card shuffling after each game. This rule invalidated Thorp's strategy, which relied on calculating probabilities based on known card positions.
What Does "Thoroughly Shuffled" Mean?
In casinos, "thoroughly shuffled" typically involves a croupier, a gambler, or an automated device performing a series of monotonic movements with the deck, usually between 10 to 25 times. Each movement alters the card arrangement, with mathematicians referring to these as "substitutions." However, does shuffling 10-25 times ensure a truly randomized deck, such that the probability of drawing a queen as the top card is 1/13?
Mathematically, if the movements are monotonous, this shuffling method proves inadequate. If the "order of substitution" is repeated frequently enough, the cards could revert to their original order, limiting the possible card combinations to just those identifiable moves.
In reality, shuffling involves varied movements. If a person or machine makes random movements, potentially achieving all possible card arrangements, the "quality" of such mixing becomes complex. This intricacy is crucial since many skilled gamblers achieve success by exploiting seemingly thorough but inadequate shuffles.
The Role of Mathematics
Mathematics offers clarity here. In "Gambling and Probability Theory," A. Reni’s calculations conclude: "If a shuffler's movements are random, then theoretically, every card arrangement is possible. However, a large number of movements is required to consider a deck truly reshuffled." This conclusion highlights two points: the shuffling quality is probabilistic and requires significantly more than the typical 10-25 moves observed in casinos.
Testing the randomness of these movements, whether by a person or device, is no small feat.
Conclusion
Returning to the article's central question: Can mathematics help gamblers devise a winning strategy, even in a simple game like twenty-one? Thorp managed to, but only by exploiting temporary rule imperfections. Mathematics won’t offer a foolproof, non-losing strategy. However, understanding the mathematical aspects of gambling can help gamblers avoid costly mistakes and prevent fraud, particularly with card shuffling.
While an all-encompassing winning strategy might be unattainable, a mathematically savvy gambler can still make the best decisions within the game’s limitations. This understanding not only enhances the enjoyment of the game but may also lead to more favorable outcomes.
