Overview

"Beat the Dealer" by Edward O. Thorp, first published in 1962, is widely credited with introducing card counting to the general public. Thorp, a mathematics professor, applied probability theory to blackjack and demonstrated that the game could be beaten with proper technique.

About This Review

This review summarizes the book's content, historical significance, and relevance based on publicly available information about the text and its impact on gambling literature. The Ace Score reflects an assessment using our book review criteria.

We encourage readers to consider that casino conditions have changed significantly since the book's publication in 1962.

Author Background

Edward O. Thorp is a mathematics professor who has taught at MIT and UC Irvine. Beyond gambling, Thorp made contributions to quantitative finance and is credited with pioneering work in applying mathematical models to financial markets.

Key Lessons and Themes

Core Concepts:

  • Mathematical proof that blackjack can have a positive expected value for players under certain conditions
  • Introduction of the Ten-Count system for card counting
  • Basic strategy optimization based on probability
  • Bankroll management principles

Main Arguments:

  • Blackjack is not purely a game of chance when deck composition changes
  • Tracking the ratio of high to low cards remaining provides useful information
  • Betting adjustments based on deck composition can shift the edge

Teaching Style

Thorp writes from an academic perspective, presenting mathematical proofs alongside practical applications. The book includes:

  • Statistical analysis and probability calculations
  • Charts and tables for strategy reference
  • Discussion of the methodology used to develop the system

The writing assumes some comfort with mathematical concepts, though Thorp attempts to make the material accessible.

Depth and Usefulness

Strengths:

  • Rigorous mathematical foundation
  • Historical documentation of early computer simulations
  • Foundational concepts still referenced today

Considerations:

  • Casino countermeasures have evolved significantly since 1962
  • Multi-deck shoes and continuous shufflers have changed the landscape
  • Some specific strategies may need updating for modern conditions

Long-Term Value

"Beat the Dealer" holds significant historical importance:

  • Credited with changing how casinos approach blackjack
  • Influenced subsequent gambling mathematics literature
  • Remains a foundational text in advantage play discussions

The book is often recommended for understanding the history and theory of blackjack advantage play, even if practitioners today use more modern resources for current techniques.

Who May Benefit From This Book

  • Readers interested in gambling mathematics history
  • Those seeking to understand the theoretical foundation of card counting
  • Students of probability and game theory
  • Anyone curious about the origins of advantage play

Consider Other Resources If

  • You want current, applicable card counting techniques
  • You prefer less mathematically dense material
  • You need information specific to modern casino conditions

Important Note

This book describes mathematical concepts and historical techniques. Success at blackjack is not guaranteed, and casino conditions vary widely. Readers should understand that casinos have implemented countermeasures and that gambling involves financial risk.

The book does not promise or guarantee winnings.

Our Verdict

"Beat the Dealer" earns an Ace Score of 9.2 based on its foundational importance to blackjack strategy and advantage play. While casino conditions have changed since 1962, the mathematical principles Thorp introduced remain relevant to understanding blackjack.
