This book retells the theoretical and technical breakthroughs made by a group of people into the gambling systems of American casinos. It follows their attempts to solve the complex physics of roulette, which leads them to invent microprocessors that fit into shoes, to use toe switches and body sensors to relay information, and ultimately to make their assault on the gambling palaces of Las Vegas. Along the way the reader is given an insight into the cutting edge of computer science: on chaos theory, strange attractors, and other concepts in contemporary physics: on the history of roulette and the many different systems devised over the years for beating the odds at all sorts of games of chance.
