Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs.

On Crosswords covers three major, interrelated topics: crossword history, kinds of crosswords and how crosswords relate to everything else. Readers will meet the personalities who have made the art form what it is today, and walk away with the most complete understanding of the form that any single book can give.

With his characteristic talent for finding the connections between writing and the stuff of our lives (most notably in his earlier hit Maps of the Imagination: The Writer as Cartographer), Peter Turchi ventures into new, and even more surprising, territory. In A Muse and a Maze, Turchi draws out the similarities between writing and puzzle-making and its flip side, puzzle-solving. He teases out how mystery lies at the heart of all storytelling. And he uncovers the magic—the creation of credible illusion—that writers share with the likes of Houdini and master magicians. In Turchi’s associative narrative, we learn about the history of puzzles, their obsessive quality, and that Benjamin Franklin was a devotee of an ancient precursor of sudoku called Magic Squares. Applying this rich backdrop to the requirements of writing, Turchi reveals as much about the human psyche as he does about the literary imagination and the creative process. With the goal of giving writers new ways to think about their work and readers new ways to consider the books they encounter, A Muse and a Maze suggests ways in which every piece of writing is a kind of puzzle. The work argues that literary writing is defined, at least in part, by its embrace of mystery; offers tangrams as a model for the presentation of complex characters; compares a writer’s relationship to his or her narrator to magicians and wizards; offers the maze and the labyrinth as alternatives to the more common notion of the narrative line; and concludes with a discussion of how readers and writers, like puzzle solvers, not only tolerate but find pleasure in difficulty. While always balancing erudition with accessibility, Turchi examines the work of writers as various as A. A. Milne, Dashiell Hammett, Truman Capote, Anton Chekhov, Alison Bechdel, F. Scott Fitzgerald, Antonya Nelson, Vladimir Nabokov, Charles D’Ambrosio, Michael Ondaatje, Alice Munro, Thomas Bernhard, and Mark Twain, elaborating and illuminating ways in which their works expand and deliver on the title’s double entendre, A Muse and a Maze. With 100 images that range from movie stills from Citizen Kane and Butch Cassidy and the Sundance Kid to examples of sudokus, crosswords, and other puzzles; from Norman Rockwell’s famous triple self-portrait to artwork by Charles Richie; and from historical arcana to today’s latest magic, A Muse and a Maze offers prose exposition, images, text quotations, and every available form of wisdom, leading the reader step-by-step through passages from stories and novels to demonstrate, with remarkable clarity, how writers evolve their eventual creations.

The Gathering 4 Gardner is a biannual conference founded—and for many years organized—by Tom Rodgers to celebrate the spirit of Martin Gardner. While primarily concerned with recreational mathematics, most of Gardner's intellectual interests are featured, including magic, literature, philosophy, puzzles, art, and rationality. Gardner's writing inspired several generations of mathematicians by introducing us to the joy of discovery and exploration, and the Gathering's aim is to continue that tradition of inspiration. This volume, a tribute to Rodgers and Gardner, consists of papers originally presented at the Gathering 4 Gardner meetings. Recreational mathematics is strongly prominent with contributions from Neil Sloane, Richard Guy, Solomon Golomb, Barry Cipra, Erik Demaine, and many others. There are games and puzzles, including new Nim-like games, chess puzzles, coin weighings, coin flippings, and contributions that combine art and puzzles or magic and puzzles. Two historical articles present the stories of combinatorial game theory and the search for God's number for Rubik's Cube. Anyone who finds pleasure in clever and intriguing intellectual puzzles will find much to enjoy in Barrycades and Septoku.

Puzzlesmiths of all skill levels will find original logic puzzles that will flex the brain, challenge assumptions, and entertain for hours. In addition to offering 200 logic puzzles, this puzzlebook includes a short tutorial on how to play each game, along with a complete back-of-book answer key.

This volume is a collection of papers on emerging concepts, approaches and ideas in information systems research. It examines theoretical and methodological issues related to both information systems development in general and the complexity of information systems as socio-technical systems. The book draws on invited papers selected from the proceedings of the 25th International Conference on Information Systems Development (ISD) held in Katowice, Poland, August 24 - 26, 2016. The invited conference papers were revised and expanded and present research that is focused on context, creativity, and cognition in information systems development. These issues are significant as they provide the basis for organizations to identify new markets, support innovative technology deployment, and enable mobile applications to detect, sense, interpret, and respond to the environment.
