The core question investigated is whether a disciplined, systematic approach to roulette can consistently overcome the house edge to defeat the bank. Norman Leigh, a professional gambler, details his 1966 operation at the Casino Municipale in Nice, where he employed a team of thirteen individuals to execute a specific betting progression. The book serves as both a historical account of this high-stakes endeavor and a technical explanation of the methodology used to challenge casino probability.

Experts and gambling enthusiasts frequently cite this work as a classic account of casino strategy and team-based betting. Readers often note the narrative clarity of the author's experience, though they caution that the system described is subject to the inherent limitations of table limits and casino surveillance.
