Bewersdorff manages a game design company in Germany and also works for a German maker of money-changing machines. He attributes both the entertainment of games and the hope of winning to uncertainty, of which he says there are three types: chance, logic, and bluff. He discusses the mathematics of each type in turn, demonstrating with a specific game or game fragment. The level of mathematics varies from chapter to chapter, but he generally tries to avoid speaking only to the adept. The original Glück, Logik und Bluff was published in 2001 by Friedr. Vieweg and Sohn Verlag, Wiesbaden. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
