Since its creation, the Cube has become many things to many people: one of the bestselling children’s toys of all time, a symbol of intellectual prowess, a frustrating puzzle with 43.2 quintillion possible permutations, and now a worldwide sporting phenomenon that is introducing the classic brainteaser to a new generation. In Cracking the Cube, Ian Scheffler reveals that cubing isn’t just fun and games. Along with participating in speedcubing competitions—from the World Championship to local tournaments—and interviewing key figures from the Cube’s history, he journeys to Budapest to seek a meeting with the legendary and notoriously reclusive Rubik, who is still tinkering away with puzzles in his seventies. Getting sucked into the competitive circuit himself, Scheffler becomes engrossed in solving Rubik’s Cube in under twenty seconds, the quasi-mystical barrier known as “sub-20,” which is to cubing what four minutes is to the mile: the difference between the best and everyone else. For Scheffler, the road to sub-20 is not just about memorizing algorithms or even solving the Rubik’s Cube. As he learns from the many gurus who cross his path, from pint-sized kids to engineering professors, it’s about learning to solve yourself.

    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. Almost a million copies of the Russian version alone have been sold.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). Many of the puzzles will be new to Western readers, while some familiar problems have been clothed in new forms. Often the puzzles are presented in the form of charming stories that provide non-Russian readers with valuable insights into contemporary Russian life and customs. In addition, Martin Gardner, former editor of the Mathematical Games Department, Scientific American, has clarified and simplified the book to make it as easy as possible for an English-reading public to understand and enjoy. He has been careful, moreover, to retain nearly all the freshness, warmth, and humor of the original.Lavishly illustrated with over 400 clear diagrams and amusing sketches, this inexpensive edition of the first English translation will offer weeks or even months of stimulating entertainment. It belongs in the library of every puzzlist or lover of recreational mathematics.

    Tens of millions of Americans solve crossword puzzles regularly, but few know a thing about their genesis. Who writes crosswords, how--and for God's sake, why? Matt Gaffney is one of two dozen people who earns a living as a cruciverbalist. In Gridlock he provides an insider's look at the people who put that puzzle in your paper every day. With verve and gusto, Gaffney traces his own starving-artist struggle to find paying puzzle gigs, including marketing hip crosswords to the Gen-X market. He then moves on to topics like the effect of computers on crossword writing, including a man versus machine battle he stages to see who writes better crosswords; the ever-evolving crossword puzzle book market, where a top-selling series now has books shaped like a toilet seat; and a trip to the American Crossword Puzzle Tournament, where the "Cru" (collective slang noun meaning "the crossword puzzle writing community") hangs out in person once a year. Gridlock also features an interview with crossword rock star Will Shortz.
