Sam Loyd (1841-1911) was the all time greatest inventor and developer of puzzles. He is described by Martin Gardner, the author of the "Mathematical Games" column in Scientific American, as "America's greatest puzzlist and an authentic American genius". His fame is world wide and books of his puzzles have been published in Russian and many other languages. This book, Sam Loyd's Cyclopedia of 5,000 Puzzles Tricks & Conundrums with Answers, was compiled by his son and published in 1914 after his death. Although many books have been written about some of Loyd's puzzles, this remains the most complete volume of all of his puzzles. This is considered to be the most fabulous and exciting collection of puzzles ever assembled in one volume. The puzzles come with wonderful illustrations.
