The New York Times bestselling author of The Year of Living Biblically goes on a rollicking journey to understand the enduring power of puzzles: why we love them, what they do to our brains, and how they can improve our world. “Even though I’ve never attempted the New York Times crossword puzzle or solved the Rubik’s Cube, I couldn’t put down The Puzzler.”—Gretchen Rubin, author of The Happiness Project and Better Than Before Look for the author’s new podcast, The Puzzler, based on this book!

Be it the formation of new cerebral pathways, their close link to insight and humor, or their community-building properties, they’re among the fundamental elements that make us human.

And maybe, in the process, solve the puzzle of our very existence. Well, almost. In The Puzzler, Jacobs meets the most zealous devotees, enters (sometimes with his family in tow) any puzzle competition that will have him, unpacks the history of the most popular puzzles, and aims to solve the most impossible head-scratchers, from a mutant Rubik’s Cube, to the hardest corn maze in America, to the most sadistic jigsaw. Chock-full of unforgettable adventures and original examples from around the world—including new work by Greg Pliska, one of America’s top puzzle-makers, and a hidden, super-challenging but solvable puzzle—The Puzzler will open readers’ eyes to the power of flexible thinking and concentration. Whether you’re puzzle obsessed or puzzle hesitant, you’ll walk away with real problem-solving strategies and pathways toward becoming a better thinker and decision maker—for these are certainly puzzling times.

Puzzlewright Guide to Diagramless Crosswords


Book Description

A complete introduction to solving diagramless crosswords, featuring dozens of puzzles! Diagramless puzzles (crosswords where the black squares aren't included, and solvers must figure out where they go) have been a popular crossword variant for decades, but they only appear rarely in newspapers and magazines. This means that there's a shortage of puzzles out there for diagramless fans. But this also causes another problem: if you've never solved a diagramless crossword before, they can seem intimidating, and there aren't a lot of opportunities to practice them. This book offers beginners extra help with solving, while offering plenty of puzzles for everyone. The extensive introductory guide woven through the book will provide step-by-step instruction, and some of the tips and tricks might be new even to veteran solvers. Starting a diagramless puzzle is the most challenging part, so multiple hints for each puzzle will help smooth the way for new solvers, while experienced solvers can go it alone without any hints for maximum challenge or pick and choose as they wish. Puzzles will start out easy and get more challenging, with crosswords of many different sizes and shapes included--and each grid's shape relates to its theme, adding to the solving satisfaction.
