The aim of this chapter is to present an unknown history of the origin and later spread of a popular matchsticks puzzle: Make a polygon from 12 matchsticks with an area of 4 “matchstick squares”. It was first published by Sam Loyd, Jr. in the Year 1925 in the newspaper “The Atlanta Constitution”. In the Year 1934, the puzzle appeared in Soviet Union, published in Russian by Yakov Perelman. Textual details and the presentation of solution suggest that Perelman didn’t invent the puzzle but “borrowed” it from Sam Loyd, Jr. In the Year1954, Boris Kordemsky largely reformulated Perelman’s puzzle, eliminating introductory figure and reducing the sought area from 4 to 3 “matchstick squares”. Puzzle’s big popularity is mainly due to Martin Gardner who published the puzzle in the Year 1957 in the journal “Scientific American” and repeated it in his many books. There was a chance that Gardner could see the puzzle in Perelman’s book “Figures for fun” that was published in English in January of the same year. Nobody of posterior authors gave credit to any one of previous authors, an unfortunate practice in the world of matchstick puzzles. A posterior reformulation of the puzzle, with the sought area reduced to two “matchstick squares”, was suggested to make finding of its solution more difficult. The chapter is closed by describing students’ creative solution of that highly challenging reformulation.
