Category : Juvenile Nonfiction
Languages : en
Pages : 102
Book Description
SOLVE MORE PUZZLES! HAVE MORE FUN! Why would a white-haired grandmother decide to write a "how-to" Sudoku book? Clearly, one reason is because she is very good at solving Sudoku puzzles. Another good reason is that she also knows how to teach. In this book she discloses her three-step Sudoku solving system in an easy-to-read-and-learn-from manner. In her three steps there are none of the strange-named techniques that are commonly used in solving Sudoku puzzles. Instead she leads you slowly and carefully through seven easily understood techniques. She believes that, like a good crossword puzzle, most Sudoku puzzles are meant For The average person to solve and not for mathematicians, analysts, computer experts, or geniuses. At the same time, she does require you to work at learning to solve them. "You do have to THINK, darlin'." She expects you to practice the techniques as you go through the steps. Her three-step system does give you a good mental workout. She says that the result of this effort should be an ability to solve almost all the puzzles you find in newspapers, magazines, and Sudoku puzzle books. For those who want to learn a little more she includes a chapter giving hints about three directions they might take. Granny wrote this book for adults like herself who want to stretch their brains, solve more puzzles, and have more fun. However, if you're willing to help them, she says that most 5-6 year-olds should be able to learn Step One, most 9-10 year-olds should be able to learn Steps One and Two, and children over 12 years should be able to learn all three steps. So, sharpen your pencil, get comfy, and let Granny hold your hand as she lovingly guides you into a lifetime of pleasure in the world of Sudoku.
