A beloved classic of recreational logic, by Hungarian mathematicians György Bizam and János Herczeg, first published in Budapest in 1972 and here translated by Yuri Danilov, a prolific and respected Soviet translator of popular science and mathematics. The book was originally conceived under the working title "School of Thinking," as the translator's preface explains, and teaches the reader to approach logical puzzle problems systematically through play rather than rote calculation, centering on a table-based method for tracking combinations of elements that the authors develop into an unusually powerful and flexible tool for solving logic puzzles of increasing sophistication. Aimed at the broadest possible readership of recreational-mathematics enthusiasts rather than specialists, requiring no formal mathematical training beyond logical reasoning itself, the collection of 85 problems became one of the most fondly remembered Soviet-era logic puzzle books, valued by generations of Russian-speaking puzzle enthusiasts and now a nostalgic and sought-after title among collectors of Soviet popular-science and recreational-mathematics publishing.
