The Moscow Puzzles
This is, quite simply, the best and most popular puzzle book ever published in the Soviet Union. Since its first appearance in 1956 there have been eight editions as well as translations from the original Russian into Ukrainian, Estonian, Lettish, and Lithuanian.Part of the reason for the book’s success is its marvelously varied assortment of brainteasers ranging from simple “catch” riddles to difficult problems (none, however, requiring advanced mathematics).
