Killer Sudoku 1


Book Description

Just when you thought it was safe to pick up a pencil Killer Su Doku is based on the original Su Doku grid, with the same rules and numbers—1 to 9—but with an added deadly twist. This time there is an element of arithmetic involved and there are few, if any, clues. The aim is to not only complete every row, column, and cube so that it contains the digits 1 to 9, but to also fill in the outlined cubes so they add up to the same number. Hints to solve the puzzle are hidden in the joined squares where only one combination of numbers applies. In the case of joined squares, if the printed number is 3, it should be 1 and 2 that go into the squares. Likewise, in the case of three joined squares, if the printed number is 6, the only combination possible is 1, 2, and 3. To add one final fiendish level, each puzzle also has a time worked out by its Japanese creators so you can try to beat the clock.

The Puzzler


Book Description

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. Convinced that puzzles have made him a better person, A.J. Jacobs—four-time New York Times bestselling author, master of immersion journalism, and nightly crossworder—set out to determine their myriad benefits. 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.
